    专利说明:
    [0001] The invention is related to a beacon tracking system, and more particularly to a portable real-time tracking system for providing personal offshore/inland location/danger alert and precautionary safety protection functions for marine activities. BACKGROUND OF THE INVENTION
    [0002] With the progress of technology, people tend to embark on various kinds of marine activities. These activities include, for example, canoeing and kayaking, sea fishing, snorkeling, and scuba diving. Before starting these activities, such as scuba diving, the personnel's location must marked firstly to protect him from being hit by vessels, and secondly in case of drastic change in marine weather, the player in water might become untraceable and highly endanger his/her life. Therefore, it is necessary to be able to send a distress signal with location to notify nearby vessels or salvage units to rescue operation.
    [0003] Here are several examples of marine accidents happened in recent years. On March 5, 2017, a scuba diver from Hong Kong with ten other divers in the Barracuda point of Sipadan island, Malaysia and was perished in a drowning accident. In the early of 2014, a Chinese diver in Phuket island, Thailand was hit in the head by a raging yacht when she surfaced. Besides, in February 2014, seven Japanese tourists went scuba diving in Bali island, Indonesia and were drifted away by strong current to end up with two of them missing. Hence, when people are engaging in marine activities or diving, locator beacon and distress alert are extremely vital for the vessels to identify the position of neighboring divers and marine activity players for avoidance of impacts. When a diver encounters emergent events, a DISTRESS signal is also needed to be sent immediately to request rescue operation.
    [0004] Please refer to FIGS. 1a and 1b, which respectively show a conventional surface marker buoy 100 used by the divers and a diver holding such surface marker buoy 100. As shown in FIG. 1a, the surface marker buoy 100 is 100-150 centimeters in length and 10-15 centimeters in diameter and is tangerine colored. The surface marker buoy 100 is used to protect the diver from being hit by vessels when he/she breaks the surface. Nowadays this surface marker buoy 100 fails to transmit wireless signal and can only help if the visuality is good. In the event of loss of contact by drifting, the surface marker buoy is of little help for rescue operation.
    [0005] In addition, another conventional marine distress alert system is a personal locator beacon (PLB). Though PLB possesses DISTRESS function, the major shortcoming of PLB is that once the distress signal is sent, the Cospas-Sarsat system notifies salvage unit to start rescue operation. As a result, there is no way to verify its reliability before an accident. Besides, the PLB can either provide real-time tracking for the vessels to avoid an impact accident. Moreover, under normal (non-distress) conditions, the PLB cannot be used to call the vessels to pick up the divers. Also, the waterproof performance of commercially available PLB is not suitable for divers(IP67).
    [0006] Furthermore, a walkie-talkie type marine safety device for diver has been proposed. This device employs analog signal with communication range typically less than 3 kilometers. If a great number of people use this device at the same time, mutual interference would occur. Due to limited effective communication range, this device is help little in marine rescue. Other relevant device uses AIS (Automatic Identification System) channel to send the distress signal in event of accident to pretend as a shipwreck accident. However, the AIS distress signal requires the Maritime Mobile Service Identity (MMSI). This means that the diver must have a MMSI for his own, and the nearby vessels must be equipped with a VHF AIS receiver to make the distress call to be valid. Unfortunately, a lot of countries do not allow individuals but ships to apply a MMSI. In other words, the distress call may be disregarded in many countries/regions.
    [0007] There is another marine safety device that is commercially available for tracking the GPS coordinate of individuals at sea by radio frequency (RF) transmitter/receiver. Nonetheless, divers rarely use this kind of marine safety device. This is because: (1) the effective transmission range of this marine safety device is about 10 kilometers only, and thus this marine safety device can only provide limited help for the rescue operation of missing persons at sea; (2) it lacks of suitable communication protocols. If many people use this device at the same time, mutual signal interference might occur, and would in turn result in communication difficulties; (3) The receiver is 5 kilograms not suitable for travel; (4) The functional design of the software does not include precautionary alerts such as : Impact Alert between diver and vessel, Out of Safe Zone Alert; and Loss of Signal Alert.
    [0008] In conclusion, the conventional technology for personal safety in marine activities has deficiencies in performance. Therefore, there is necessity to adapt the design of the marine beacon system to ensure the safety of people involved with marine activity. SUMMARY OF THE INVENTION

    [0013] In the above descriptions, the transmitter and the receiver can be integrated into a transceiver which can be set for operation of a transmitter or a receiver by switching the switches.
    [0014] The front of transceiver is designed with five slide switches, including: (1) an illumination switch; (2) a receiver setting switch; (3) a transmitter setting switch; (4) a transmitter DISTRESS function switch; and (5) a transmitter OK function switch. By simultaneously turning on the receiver setting switch and the transmitter setting switch, transceiver can be set to an auto-testing mode for the transmitter thereof to transmit the auto-testing data to the receiver of another transceiver and display these data on the touch screen of a corresponding smart device through Wi-Fi communication.
    [0015] In the above descriptions, the transceiver can be set to a transmitter mode. The tracking data can be sent by the transmitter setting switch and a built-in firmware. The tracking data include: (1) an identification code; (2) a latitude and a longitude; and (3) a status code. The status code can indicate four status: OK status, DISTRESS status, DISTRESS TERMINATING status and TESTING status. Under the TESTING status, the transceiver can transmit the auto-testing data.
    [0016] The auto-testing data include: a model number of the transmitter; an indication of whether switching functions of all the switches is normal; a remaining power level of the battery; and an indication of whether the GPS positioning is successful and its positioned latitude and longitude.
    [0017] In the above descriptions, the transceiver can be set to a receiver mode. The receiver can receive the identification code of the transmitter, the latitude and the longitude; the status code, and the auto-testing data at the same time, and send these data to a corresponding smart device through Wi-Fi communication. The central processing unit (CPU) of the corresponding smart device can execute the App for real-time tracking and manage, analyze, record, and share these data to provide the distress alert and precautionary safety protection functions by manipulating the touch screen.

    [0024] BENEFITS OF THE INVENTION: One of the advantages of the invention is that the receiver and the transmitter can be integrated into a single transceiver. This can simplify the manufacturing process, enhance the yield, simplify the certification procedure in different countries and lower the certification cost.
    [0025] Another advantage of the invention is that all the modules within the transmitter and the receiver are not connected to each other with cables but with board-to-board connectors. This can suppress the adverse temperature effect against the sheath of the cables, thus enhancing the yield of assembly and prolonging the lifespan of the transceiver.
    [0026] Another yet advantage of the invention is that the transmitter and the receiver employ inductive magnetic switch and a wireless charging technique to render a seamless housing surface, which would in turn result in a high-level hermetic and waterproof performance.
    [0027] Besides, the invention possesses an advantage that the transmitter and the receiver employ a built-in communication protocol and a time-division technique to achieve multiple (transmitters) to multiple (receivers) communication simultaneously with a single RF channel.

The waterproof O-ring is placed between the outer upper housing 421 and the transparent outer lower housing 422 to form an outer housing 480. The multiple screws 441 are used to lock and seal the outer upper housing 421 and the outer lower housing 422. The transparent outer lower housing 422 is mounted outside the internal housing 430 to wrap around the internal housing 430. The switch guiding plate 410 is mounted on a front surface of the outer lower housing 422 with the five slide switches 411-415 mounted thereon (the five slide switches 411-415 will be discussed in detail later). Each slide switch can be slid left and right along a sliding track in one of five sliding grooves of the switch guiding plate 410. When the slide switches 411-415 are slid to the rightmost place of the sliding groove, it indicates an ON state; when the slide switches 411-415 are slid to the leftmost place of the sliding groove, it indicates an OFF state. The illumination LED cover 450 is round, and the display bezel 460 is rectangular. Viewed from the front surface of the internal housing 430, both the illumination LED cover 450 and the display bezel 460 are mounted on the right side of internal housing 430. The company logo 470 is oval and is mounted on a top surface of the external upper housing 421. The projecting RF antenna 423 of the outer upper housing 421 is sheathed for protection. The transparent outer lower housing 422 is provided with a bottom bolt 442 to fasten its bottom. When the transceiver is in a transmitter mode, a rope may be used to fix between transceiver and the person using it. When the transceiver is in a receiver mode, other accessory may be used to fix the receiver to the vessel.

    [0041] Next, referring to FIG. 8, the Security Patrol Interface (or Safety Surveillance/Monitoring Interface) of the portable marine beacon system according to the invention is illustrated. This interface has the following functions: (1) monitor the ID/location/status of all transmitters on a real-time basis; (2) in the event of hazard, automatically trigger an audible alarm and an alert notification 850 on the screen. Each alert notification has four types of alerts, as shown in FIG. 8, including precautionary alerts for safety protection : (2a) human-vessel impact (collision) alert; (2b) loss of signal (over time) alert; (2c) out of safe zone (over distance) alert; and (2d) DISTRESS (SOS) alert 840. Reference numeral 860 indicates the coordinates of a vessel, i.e. the coordinates of the smart device 230. In Fig. 8, the vessel is located at the center of the radar chart. Each icon(circle or star shape) indicates ID/location/status data of a person (transmitter). The upward pointing arrow 833 indicates the exit point (out of the water) of a dive group. The downward pointing arrow 834 indicates the entry point (into the water) of a dive group.
    [0042] In the above descriptions, the precautionary alert for collision 810 in (2a) is used to provide a collision warning on the monitoring screen and an audible alarm with respect to any transmitter data detected inside a hazardous zone with risk of collision between human and vessel. Reference numeral 811 represents the area of the hazardous zone. This hazardous zone includes a sector of 135° ahead of the vessel (receiver) with a radius 1 kilometer and a circular area with a radius 500-meter within which the vessel is located. If a person (transmitter), such as Jim 812, is detected to be located within this hazardous zone, the alert is triggered. When this alert is triggered, the icon of person and alert 810 shown on the screen will blink together with an audible alarm.
    [0043] The loss of signal (over time) alert 820 in (2b) is triggered if a person (transmitter), for example Joe 821, does not send data by the end of the planned exit time, the alert 820 and the icon(last coordinates) of Joe will blink together with an audible alarm.
    [0044] The over distance alert 830 (2c) is triggered if a person (transmitter), for example Lee 831, is located outside a safe zone, the alert 830 will blink together with an audible alarm and the icon of the person will be blinking. The circle zone 832 represents the safe zone for activity configured for a group of persons.
    [0045] The distress (SOS) alert 840 in (2d) is initiated by a transmitter 841 (person 012). When this alert is triggered, the alert 840 will blink together with an audible alarm and the original icon of the person issuing the distress call will be replaced by a red star. After a DISTRESS Status is triggered, only swapping between DISTRESS status and DISTRESS TERMINATING status is allowed. Once the Distress status is ended, the transmitter will automatically issue a distress terminating notification which will be shown on the screen as a green star 842 (persons 010, 017) continuously for one hour, allowing the neighboring ships to know that the person has been rescued to avoid futile rescue.
    [0046] In FIG. 8, the left-side pull-down function menu includes: 891: Tx/Redirect to the Transmitter Management Interface, 892: Plan/Redirect to the Activity planning Interface (or Alert Setting Interface); 893:Surv/Redirect to the Security Patrol Interface (or Safety Surveillance/Monitoring Interface); 894: Center/Mark the coordinates of the vessel at the center of the screen; 895: PB/Redirect to the Record Playback Interface (or History Playback Interface); and 896: Help/Get help from users guide.
    [0047] In the above descriptions, the icons of the transmitter in screen will be marked by different color and shape in radar chart to handle various status. However, the drawings of the present invention are prepared in black and white instead of colorful drawings.
    [0048] Eventually, referring to FIG. 9, the Record Playback Interface (or History Playback Interface) in the portable marine beacon system according to the invention is illustrated. In FIG. 9, this interface has the functions to replay/share/delete recorded historical data of all transmitters in entire activity. The user first selects the date 930 from the right-side pull-down function menu and then selects the recorded data 910 of the person 940, Sam. Sam's coordinates will then be shown on the screen. The backward/forward buttons 920 and 921 can be clicked to show the previous/next data. The left-side pull-down function menu includes: 991: Tx/Redirect to the Transmitter Management Interface, 992: Plan/Redirect to the Activity Planning Interface (or Alert Setting Interface); 993: Surv/Redirect to the Security Patrol Interface (or Safety Surveillance/Monitoring Interface); 994: PB/Redirect to the Record Playback Interface (or History Playback Interface); 995: Center/Mark the coordinates of the vessel at the center of the screen; 996: Share/share or delete the recorded historical data; and 996: Help/Get help for operations.
    [0049] In the present invention, the transceiver can attain high-level hermeticity and waterproof by means of the following special designs:1. Inductive magnetic switch: The aforesaid five slide switches each contains a magnet sealed therein. When the slide switch is moved to the leftmost position (OFF) or to the rightmost position (ON), the magnetic sensors will convert magnetic variation into voltage high/low alteration as an ON/OFF control signal to the microprocessor, thereby accomplishing the ON and OFF operation. As a result, the invention can rule out the disadvantage of conventional switches that water could permeate into the housing through the apertures on the surface of the housing caused by the switches mounted on the housing. Hence, the invention can ensure the integrally formed nature and the waterproof quality of the housing. 2. Wireless charging: The traditional charging method using wire requires the use of a power socket, which is against the requirements of the housing for being integrally formed and waterproof. The present invention uses wireless charging at the absence of any socket and wires, so there is no sacrifice in waterproof requirement due to charging needs.
    [0050] By virtue of the design of the invention, the transceiver of the invention is resistant to a underwater pressure up to 13 Bar, and in turn is suitable for technical diver at a depth of 120 meters or more.
    [0051] The portable marine beacon system invention can integrate a receiver and a transmitter into a single transceiver to simplify the manufacturing process and enhance the yield. Also, the invention can simplify the certification process and lower the certification cost in various countries and increase the flexibility for use.
    [0052] INDUSTRIAL PRACTICABILITY: In summary, compared to the prior art, the invention is advantageous over the prior art in terms of the following aspects: 1. The invention provides a Marine Beacon Manager App for real-time tracking application. This App provides operations of the Transmitter Management Interface, the Activity Planning Interface (or the Alert Setting Interface), the Security Patrol Interface (or the Safety Surveillance/Monitoring Interface), and the Record Playback Interface (or the History Playback Interface) through the touch screen. Thus, the invention can provide the user with positioning/distress alert at sea and in land and precautionary safety protection functions comprehensively. 2. The transceiver employs inductive magnetic switch and a wireless charging technique to accomplish a seamless housing, thereby achieving the high-level hermetic and waterproof performance. 3. The invention employs a single RF channel and a time-division technique to conduct multiple (transmitters) to multiple (receivers) communication without occupying excessive frequency channels. 4. The invention can conduct autonomous communication without the need of any other network or Internet. Hence, the invention can be applied in a remote area onshore or offshore, even in a marine accident or in case of a devastating earthquake ravaging the existing communication systems.
