    A CONTROL UNIT FOR INTERFACING WITH A BLASTING PLAN
    LOGGER BACKGROUND OF THE INVENTION: Field of the Invention: The present application generally relates to blasting operations. In particular, the present appli- cation relates to a control unit for interfacing with a blasting plan logger.
    Description of the Related Art: Planning and implementing a blasting operation currently requires typically at least four separate de- vices: a purpose-built Global Positioning System (GPS) device, a computer, a purpose-built logger device and an initiating device.
    The purpose-built GPS-device is used to obtain GPS locations of the bore holes. Alternatively, GPS lo- cations of the bore holes are not obtained at all. Such purpose-built GPS-devices are typically accurate but expensive. The computer has design software usually pro- vided by detonator manufacturer (s). Typically, a blast- ing plan can only be created with this software. A com- pleted blasting plan is transferred from the computer to the purpose-built logger device via a Bluetooth or cable connection. The purpose-built logger device is o then used to scan barcodes or Quick Response (QR) codes > of the detonators that will be used at the blasting O field. This information is sent to the initiating device 7 which is used to blast the field. Finally, the initiat- A 30 ing device will be connected to a primary wire of the E field, and the field will be blasted with the initiating LO device. N Typically, the current devices needed to access 2 the blasting plan and program the detonators are hand- N 35 held devices in the sense that at least one hand (and typically both hands) is required to hold and operate these devices. In other words, the user's (i.e. the blasting person setting the detonators and explosives for the bore holes at the field) hands are not free for other tasks.
    Furthermore, the user's field of vision needs to be fixed on these devices (e.g. looking down and focusing on the display of the logger device that the user is keeping in his/her hands).
    The above leads to diminished efficiency and safety during work. This is a particularly significant disadvantage when the work includes dangerous tasks, such as working with detonators and explosives.

    DETAILED DESCRIPTION OF THE INVENTION: Reference will now be made in detail to embod- iments of the present invention, examples of which are illustrated in the accompanying drawings.
    The detailed description provided below in connection with the ap- pended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be con- structed or utilized.
    The description sets forth the functions of the example and the sequence of steps for constructing and operating the example.
    However, the same or equivalent functions and sequences may be ac- complished by different examples.
    Figure 1 illustrates an overview of an example system 100 in which various embodiments of the present disclosure may be implemented.
    An example representation of the system 100 is shown depicting a network 170 that connects entities such as a wearable system 200, an initiating device 110, an optional computing device 120, and a remote database 130. The network 170 may be a centralized network or may comprise a plurality of sub- networks that may offer a direct communication between the entities or may offer indirect communication between the entities.
    Examples of the network 170 include wire- less networks, wired networks, and combinations thereof. o Some non-exhaustive examples of wireless networks may > include wireless local area networks (WLANs), Bluetooth O or Zigbee networks, cellular networks and the like.
    Some 7 30 non-exhaustive examples of wired networks may include YT local Area Networks (LANs), Ethernet, Fiber Optic net- E works and the like.
    An example of a combination of wired LO networks and wireless networks may include the Internet.
    N The wearable system 200 may include e.g. the 2 35 wearable system 200 of Fig. 2A.
    The optional computing N device 120 may include e.g. a smart phone, tablet com-
    puter, laptop computer, a two-in-one hybrid computer, a desktop computer, a network terminal, or the like.
    As described in more detail below, software deployed in a control unit 220 of the wearable system 200 may be used or may function as a blasting plan logger.
    Herein, the “blasting plan logger” refers to software and/or hard- ware for facilitating planning and/or implementing blasting operations.
    The control unit 220, the initiating device 110 and/or the optional computing device 120 may utilize the remote database 130. For example, bore hole maps, topo- graphic maps and/or blasting plans utilized in the var- ious embodiments described herein may be stored in the database 130 in addition to storing their local copies in the control unit 220, the initiating device 110 and/or the optional computing device 120. The system 100 further includes electronic det- onators 141, 142. As is known in the art, electronic (or digital) detonators are designed to provide precise con- trol necessary to produce accurate and consistent blast- ing results in a variety of blasting applications e.g. in mining, quarrying, and construction industries.
    Typ- ically, delays for electronic detonators may be pro- grammed in one-millisecond increments from 1 millisecond to 16000 milliseconds.
    The delay assigned for an elec- tronic detonator is programmed to a chip comprised in the electronic detonator.
    An electronic detonator fur- ther comprises a detonator wire which is used to connect > the electronic detonator to a primary wire of the blast- N ing field.
    The primary wire in turn is connected to the 3 30 initiating device 110. Each electronic detonator also ™~ has an associated identification code which may be Ek unique to the electronic detonator.
    The identification * code may be comprised in an identifier 141 1, 142 1 of = the respective electronic detonator 141, 142. In at 3 35 least some of the embodiments, the identifier 141 1, S 142 1 may comprise a NFC tag.
    Alternatively, the iden-
    tifier 141 1, 142 1 may comprise a visual identifier,
    such as a barcode, a OR (quick response) code, or nu- merical code.
    Figure 1 also shows a blasting field 150 with one or more bore holes 161-168 configured to receive explosives and one or more electronic detonators 141,
    142. The blasting field 150 may be located e.g. in a mine, a quarry, a construction site, or the like. Typ- ically, there are several bore holes in a blasting field. For example, a blasting field in a quarry may have two hundred or more bore holes. Often, the bore holes are arranged in a grid like pattern. The distance between two bore holes may be e.g. substantially two meters in direction and substantially three meters in another direction. The depth of a bore hole may be e.g. substantially 2-30 meters.
    The locations of the bore holes 161-168 are indicated in a bore hole map and transferred to a blast- ing plan. The bore hole map and the blasting plan may also include other information related to the bore holes 161-168, such as depth and/or diameter and/or inclina- tion of each bore hole. When a given bore hole is as- signed to receive two or more detonators, these detona- tors are typically arranged at different depths in the bore hole. In such a case, the blasting plan may also include information about the assigned depth of each detonator in the bore hole, and/or information about the assigned order in which the detonators are to be placed > in the bore hole (the detonator to be placed first in N the bore hole will typically be the one closest to the 3 30 bottom of the bore hole, and the detonator to be placed ™~ last in the bore hole will typically be the one closest Ek to the surface of the bore hole).
    * The locations and dimensions of the bore holes = 161-168 together with the associated detonator delays 3 35 may be used to control the direction of the power of the S blast, e.g. away from nearby buildings, electric power lines, roads, and the like. The initiating device 110 is used to initiate the blasting of the field 150.
    Figure 2A is a block diagram of a wearable system 200 in accordance with an example embodiment. The wearable system 200 is configured to facilitate hands- free interfacing with a blasting plan logger.
    The wearable system 200 comprises a headset 210 and a control unit 220 for interfacing with a blasting plan logger. The wearable system 200 may further com- prise a handset 230.
    As shown in Figure 2B, the headset 210 com- prises a wearable display 211. The headset 210 may fur- ther comprise a first short-range wireless (such as Bluetooth or the like) transceiver 212, a microphone 213, a digital camera 214, and/or a speaker 215. The wearable display 211 may be comprised e.g. in a safety helmet visor or in smart glasses. The headset 210 may comprise e.g. an augmented reality (AR) headset, a vir- tual reality (VR) headset, or a mixed reality (MR) head- set.
    As shown in Figure 2D, the handset 230 com- prises a wearable near-field communication (NFC) tag reader 231. The wearable near-field communication tag reader 231 may be comprised e.g. in a glove (such as a working glove or the like), or the wearable near-field communication tag reader 231 may be e.g. wrist-attach- able. The handset 230 may further comprise a third = short-range wireless (such as Bluetooth or the like) N transceiver 232. 3 30 As is known in the art, NFC is a short-range ™~ wireless connectivity technology standard designed for =E simple and safe communication between electronic de- * vices. The technology is an extension of the ISO/IEC = 14443 proximity-card standard. In an embodiment, the 3 35 near field communication comprises radio-frequency S identification (RFID). As is commonly known, the term “radio-frequency identification” refers to a technology that uses communication via electromagnetic waves to exchange data be-tween a terminal and an object such as a product, animal, or person for the purpose of identi- fication and tracking, for example. As shown in Figure 2C, the control unit 220 for interfacing with a blasting plan logger comprises one or more processors 221, and one or more memories 222 that comprise computer program code 223. The control unit 220 may further comprise a second short-range wire- less (such as Bluetooth or the like) transceiver 224, and/or a long-range wireless transceiver 226 for com- municating with the external communication network 170. Furthermore, the control unit 220 may be connected to a high-accuracy positioning unit 225. The high-accuracy positioning unit 225 may be integrated with the control unit 220, in which case the control unit 220 may be connected to the high-accuracy positioning unit 225 via a suitable internal interface. Alternatively, the high- accuracy positioning unit 225 may be external to the control unit 220, in which case the control unit 220 may be connected to the high-accuracy positioning unit 225 via a suitable external interface. Although the control unit 220 is depicted to include only one processor 221, the control unit 220 may include more processors. In an embodiment, the memory 222 is capable of storing instructions, such as an op- erating system and/or various applications.
    = Furthermore, the processor 221 is capable of N executing the stored instructions. In an embodiment, the 3 30 processor 221 may be embodied as a multi-core processor, = a single core processor, or a combination of one or more = multi-core processors and one or more single core pro- * cessors. For example, the processor 221 may be embodied = as one or more of various processing devices, such as a 3 35 coprocessor, a microprocessor, a controller, a digital S signal processor (DSP), a processing circuitry with or without an accompanying DSP, or various other processing devices including integrated circuits such as, for ex- ample, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a mi- crocontroller unit (MCU), a hardware accelerator, a spe- cial-purpose computer chip, or the like. In an embodi- ment, the processor 221 may be configured to execute hard-coded functionality. In an embodiment, the proces- sor 221 is embodied as an executor of software instruc- tions, wherein the instructions may specifically con- figure the processor 221 to perform the algorithms and/or operations described herein when the instructions are executed.
    The memory 222 may be embodied as one or more volatile memory devices, one or more non-volatile memory devices, and/or a combination of one or more volatile memory devices and non-volatile memory devices. For ex- ample, the memory 222 may be embodied as semiconductor memories (such as mask ROM, PROM (programmable ROM), EPROM (erasable PROM), flash ROM, RAM (random access memory), etc.), or the like.
    In an embodiment, the blasting plan logger may be implemented as software, and stored e.g. in the memory 222 of the control unit 220. In another embodi- ment, the blasting plan logger may be implemented as a device or software external to the wearable system 200, and the control unit 220 may be configured to communi- cate with the blasting plan logger e.g. via the long- = range wireless transceiver 226.
    N The high-accuracy positioning unit 225 may com- 3 30 prise a positioning unit capable of positioning accuracy = of at least substantially 50 centimeters, and/or capable Ek of utilizing Lb positioning signaling. Examples of po- * sitioning systems include global navigation satellite = systems (GNSS), such as Global Positioning System (GPS), 3 35 Global Navigation Satellite System (GLONASS), Galileo, S and the like.
    The 15 frequency band is used at least by GPS. This frequency falls into a range for aeronautical nav- igation, with little or no interference under any cir- cumstances. The L5 consists of two carrier components that are in phase quadrature with each other. 15 (also known as "the third civil GPS signal”) is planned to support e.g. safety-of-life applications for aviation and provide improved availability and accuracy.
    An example of the high-accuracy positioning unit 225 includes GPS chip BCM47755 from Broadcom, and the like.
    The control unit 220 for interfacing with a blasting plan logger is connected at least to the head- set 210 comprising the wearable display 211. The control unit 220 is connected to the headset 210 via a first interface 240, as shown in Figure 2A. In an embodiment, the control unit 220 and the headset 210 are physically separate devices, and the first interface 240 may com- prise e.g. a first short-range wireless connection be- tween the first short-range wireless transceiver 212 and the second short-range wireless transceiver 224.
    In another embodiment, the control unit 220 and the headset 210 are integrated in a single device, and the first interface 240 may comprise e.g. an internal interface, such as a suitable centralized circuit or the like. The centralized circuit may be various devices configured to, among other things, provide or enable > communication between the control unit 220 and the head- N set 210. In certain embodiments, the centralized circuit 3 30 may be a central printed circuit board (PCB) such as a ™~ motherboard, a main board, a hand-held apparatus board, =E or a logic board. The centralized circuit may also, or * alternatively, include other printed circuit assemblies = (PCAs) or communication channel media. 3 35 In embodiments comprising the handset 230, the S control unit 220 for interfacing with a blasting plan logger is connected to the handset 230 via a second interface 250, as shown in Figure 2A. In an embodiment, the control unit 220 and the handset 230 are physically separate devices, and the second interface 250 may com- prise e.g. a second short-range wireless connection be- tween the third short-range wireless transceiver 232 and the second short-range wireless transceiver 224. In an embodiment, the control unit 220 and the handset 230 are integrated in a single device, and the second interface 250 may comprise e.g. an internal in- terface, such as a suitable centralized circuit or the like. The centralized circuit may be various devices configured to, among other things, provide or enable communication between the control unit 220 and the hand- set 230. In certain embodiments, the centralized circuit may be a central printed circuit board (PCB) such as a motherboard, a main board, a hand-held apparatus board, or a logic board. The centralized circuit may also, or alternatively, include other printed circuit assemblies (PCAs) or communication channel media. In embodiments in which the control unit 220 is physically separate from the headset 210 and the handset 230, the control unit 220 may be comprised e.g. in a portable computing device, such as a smart phone, a smart watch, or the like, that can be kept in a pocket or otherwise carried in a hands-free manner, so as not to hinder the hands-free operation of the described em- bodiments. > In an embodiment, the control unit 220 may be N comprised or integrated in a smart phone (or the like), 3 30 such that the various functionalities of the control ™~ unit 220 described herein are implemented as software Ek executed by the hardware of the smart phone. That is, * at least the at least one processor 221 and the at least = one memory 222 may be those of the smart phone. In this 3 35 embodiment, an interface between the control unit 220 S and the smart phone may comprise a software interface.
    Further in this embodiment, the headset 210 and/or the handset 230 are physically separate from the smart phone comprising the control unit 220, and the control unit 220 may communicate with the headset 210 and/or the handset 230 via a suitable wireless interface (s) of the smart phone, such as a suitable radio interface(s) of the smart phone.
    In an embodiment, the control unit 220 may be comprised or integrated in a smart watch (or the like), such that the various functionalities of the control unit 220 described herein are implemented as software executed by the hardware of the smart watch. That is, at least the at least one processor 221 and the at least one memory 222 may be those of the smart watch. In this embodiment, an interface between the control unit 220 and the smart watch may comprise a software interface. Further in this embodiment, the headset 210 and/or the handset 230 are physically separate from the smart watch comprising the control unit 220, and the control unit 220 may communicate with the headset 210 and/or the handset 230 via a suitable wireless interface(s) of the smart watch, such as a suitable radio interface(s) of the smart watch.
    The control unit 220 as illustrated and here- inafter described is merely illustrative of a control unit that could benefit from embodiments of the inven- tion and, therefore, should not be taken to limit the scope of the invention. It is noted that the control > unit 220 may include fewer or more components than those N depicted in Fig. 2C. 3 30 The at least one memory 222 and the computer ™~ program code 223 are configured to, with the at least Ek one processor 221, cause the control unit 220 to at + least operate the wearable display 211 via the first = interface 240 to display information from the blasting 3 35 plan logger to a user on the wearable display 211. S Herein, the "user” refers to a user of the control unit 220 and thus the user of the wearable system 200, such as a person setting detonators and/or explosives for bore holes at a blasting field.
    The information from the blasting plan logger may include e.g. information re- lated to the operation of the blasting plan logger, and/or information related to a blasting plan.
    For ex- ample, the information from the blasting plan logger may include information related to a bore hole map associ- ated with the blasting field 150 the user is currently working on.
    Examples of such information may include locations, depths, diameters, and/or inclinations of bore holes, as well as information about assigned depth of each detonator in a bore hole, and/or information about a assigned order in which detonators are to be placed in a bore hole (when a given bore hole is assigned to receive two or more detonators). As discussed above, the headset 210 may op- tionally comprise the microphone 213. The at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to operate the microphone 213 via the first interface 240 to receive a voice command from the user of the control unit 220 for operating the control unit 220 and/or for interacting with the blast- ing plan logger.
    Furthermore, in this optional embodi- ment, the at least one memory 222 and the computer pro- gram code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to > execute the received voice command.
    Examples of voice N commands for operating the control unit 220 may include 3 30 e.g. voice commands for activating/deactivating the con- ™~ trol unit 220 and/or other devices connected to it (such Ek as activating/deactivating the wearable display 211) and * any other operational voice commands.
    Examples of voice = commands for interacting with the blasting plan logger 3 35 may include e.g. voice commands for operating the blast- S ing plan logger and/or for accessing/entering/updating information related to a blasting plan.
    For example, the voice commands for interacting with the blasting plan logger may include voice commands for operating access- ing/entering/updating detonator delays for a bore hole.
    The at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to operate the microphone 213 via the first interface 240 to receive a voice sample from the user. Further- more, in this optional embodiment, the at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to perform voice recognition on the received voice sample.
    Herein, voice recognition (also called speaker recognition) refers to the identification of a person from characteristics of voices (i.e. voice biometrics). In other words, voice recognition aims to recognize who is speaking. More specifically, herein voice recognition may be used to verify that the speaker is a person authorized to set the detonators and explosives for the bore holes at the blasting field.
    As discussed above, the headset 210 may op- tionally comprise the digital camera 214. The at least one memory 222 and the computer program code 223 may further be configured to, with the at least one proces- sor 221, cause the control unit 220 to operate the dig- ital camera 214 via the first interface 240 to read a 2 visual identifier of an electronic detonator 141, 142.
    N The visual identifier of an electronic detonator may 3 30 comprise e.g. a barcode, a QR (quick response) code, or ™~ numerical code (such as a serial number or the like).
    Ek The at least one memory 222 and the computer * program code 223 may further be configured to, with the = at least one processor 221, cause the control unit 220 3 35 to operate the digital camera 214 via the first inter- S face 240 to record a video log about activities of the user. Recording a video log allows maintaining a com- plete record of everything that happened e.g. when set- ting the detonators and explosives for the bore holes at the blasting field. This can be useful e.g. for ful- filling legal requirements, for determining what hap- pened if something goes wrong, and for training pur- poses. The at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to operate the digital camera 214 via the first inter- face 240 to receive a video feed at least partially covering an eye of the user. Furthermore, in this op- tional embodiment, the at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to perform biometric user identification based on the received video feed. Such biometric user identi- fication based on the received video feed may include e.g. iris recognition and/or retinal scanning. Herein, biometric user identification based on the received video feed may be used to verify that the user is a person authorized to set the detonators and explosives for the bore holes at the blasting field.
    As discussed above, the control unit 220 may optionally be connected to the high-accuracy positioning unit 225. The at least one memory 222 and the computer = program code 223 may further be configured to, with the N at least one processor 221, cause the control unit 220 3 30 to determine the location of the user based on signaling ™~ received by the high-accuracy positioning unit 225. I As discussed above, the control unit 220 may * optionally be connected via the second interface 250 to = the handset 230 comprising the wearable near-field com- 3 35 munication tag reader 231. The at least one memory 222 S and the computer program code 223 may further be con- figured to, with the at least one processor 221, cause the control unit 220 to operate the wearable near-field communication tag reader 231 via the second interface 250 to read an identifier of an electronic detonator 141, 142 comprised in a near-field communication tag 141 1, 142 1 associated with the electronic detonator 141, 142.
    In an example, the user or blasting operator sets the detonators 141, 142 and primary explosives to the bore holes 161-168. The setting is performed with the control unit 220 by opening an accepted blasting plan that has e.g. been downloaded and stored to the control unit 220 from the remote database 130. Here, each detonator 141, 142 may contain an identifying NFC tag 141 1, 142 1 which is read e.g. with the wearable near-field communication tag reader 231. At the same time, the high-accuracy positioning unit 220 will pro- vide coordinates of the location in which the NFC tag was read. All the detonators may be set this way at every bore hole. The control unit 220 may update the blasting plan with information about the read and iden- tified detonators.
    Alternative to using the high-accuracy posi- tioning unit 225, the at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to determine the location of the user based on one or more received voice commands. In this case, the > location may be e.g. relative to a bore hole map. As an N example, a voice command may include the phrase "row 3 30 one, bore hole one” or the like, indicating that the ™~ location of the user is at bore hole one of row one of Ek a current bore hole map. * The at least one memory 222 and the computer = program code 223 may further be configured to, with the 3 35 at least one processor 221, cause the control unit 220 S to operate the wearable display 211 via the first in- terface 240 to provide visual feedback to the user. As an example, the visual feedback may include a visual indicator for successfully/unsuccessfully performing a task related to operating the blasting plan logger and/or to accessing/entering/updating information re- lated to a blasting plan.
    For example, when the user successfully enters/updates a detonator delay for a bore hole, this may be confirmed with a suitable visual in- dicator, such as changing the color of a display inter- face element.
    The at least one memory 222 and the computer program code 223 may further be configured to, with the at least one processor 221, cause the control unit 220 to operate the speaker 215 via the first interface 240 to provide audio feedback to the user.
    As an example, the audio feedback may include an audible indicator for successfully/unsuccessfully performing a task related to operating the blasting plan logger and/or to access- ing/entering/updating information related to a blasting plan.
    For example, when the user successfully enters/up- dates a detonator delay for a bore hole, this may be confirmed with a suitable audible indicator, such as a beep or the like.
