    [0002] Surveying instrument security device
    [0004] OBJECT OF THE INVENTION
    [0006] The present invention falls within the technical field of topographic instruments, and refers in particular to a security device for topographic instruments, configured to act, firstly, as an anti-theft element and, secondly, as an element that allows monitoring of the position of the instruments in the event that they have been stolen.
    [0008] To do this, the device comprises an external casing, which can be attached to the tribrach and to the platform of the most common topographic and geodetic instruments, inside which a plurality of electronic elements are housed that allow both anti-theft warning and remote monitoring actions. .
    [0010] BACKGROUND OF THE INVENTION
    [0012] The instruments usually used in the field development of topographic and geodetic works are composed of a plurality of elements, from the simplest such as levels, to others much more sophisticated such as GNSS receivers, laser scanners, or those known as total stations, whose Market value can reach tens of thousands of euros.
    [0014] A total station is called an electro-optical device that basically consists of the incorporation of a distance meter and a microprocessor to an electronic theodolite. Some of the elements it presents are liquid crystal displays, warning LEDs, independent lighting from sunlight, calculator, distance meter or trajectory-tracking elements, all of this in electronic format to allow the dumping of data and measurements made on equipment. IT. They are also usually equipped with various simple programs that allow, among others, operations such as calculating coordinates in the field, setting out points easily and efficiently, or calculating azimuths and distances.
    [0016] Field work methods require the field technician to move considerable distances away from the instrument and sometimes for long periods of time. The The most extreme case is the one corresponding to jobs that make use of GNSS receivers, in which there is a fixed base that communicates with a receiver carried by the technician, which can be found miles away.
    [0018] On other occasions, the very type of work to be carried out allows automations that make the presence of a field technician unnecessary, as in the case of auscultation operations on railways, large structures, dams, tunnels, etc., where they are used Robotic total stations that operate autonomously and programmed, sending data to an external control station, which may be located at a great distance from the place where the measurements are made.
    [0020] The high price and the low surveillance conditions to which the instruments are subjected for long periods of time cause thefts to occur on a regular basis, with the understandable inconvenience and damage that this causes, both to surveying professionals and companies. instrument insurers. The negative impact caused is very significant, and translates into high replacement costs, delays in delivery and project execution schedule, time spent locating equipment, formalizing complaints, etc.
    [0022] In the current state of the art, various mechanical devices that can be attached to topographic instruments are known, conceived to make subtraction difficult, mainly trying to be a more dissuasive than effective element, since they do not allow any type of monitoring and / or location of the instruments in in case the robbery ever takes place. Alternative solutions are also known, mainly based on remote locking and unlocking systems for the operation of instruments in the event of theft, which are not particularly effective either.
    [0024] US Patent Publication Number US2012185168 describes a tracking system that includes a dispatch system and a mobile object module. The delivery system includes a processing device, a position information receiver configured to receive position information associated with a moving object, a position data store, and a report module configured to report position information to a first. non-proprietary entity, where the reporting module includes a verification unit. The moving object module determines the position information corresponding to the moving object and transmits the position information to the position information receiver.
    [0025] Said American patent is focused on a tracking device specially configured for coupling with specific models of total stations. This device, in combination with a specific application, allows remote monitoring of the equipment, by paying an annual subscription.
    [0027] From the foregoing it can be deduced that surveying and geodesy equipment are constantly threatened by theft both in field work and even during storage. It is estimated that in the year 2013 in the USA these equipment were stolen for a value of more than 300 million dollars. Only 21% of the stolen equipment could finally be recovered.
    [0029] Therefore, the need arises to have a security device specifically configured for the peculiarities of topographic instruments, which has a deterrent and anti-theft effect and which also allows remote monitoring and location of said instruments. It is also desirable that said device have a simple, inexpensive construction and easily attachable to any topographic instrument, regardless of its type, brand or model.
    [0031] DESCRIPTION OF THE INVENTION
    [0033] The object of the invention consists of a topographic instrument security device designed to, firstly, deter the theft of said instruments, secondly, send a warning signal in the event that theft is taking place and, thirdly , permanently position the instruments, in case it has finally been stolen.
    [0035] As is known, topographic instruments, of whatever type, are usually arranged on a ground anchoring support, known generically as a tripod, with the intermediation of a tribrach, designed to allow a correct adjustment. Tripods usually have three supports, which coincide with each of the respective tripod legs, as well as a temporary coupling element with said tripod, usually consisting of a hole through which a screw can be screwed into an upper end of the tripod body. .
    [0037] The tribraches have a front face, confrontable to the instruments, and a rear face, confrontable to the tripod and from which the aforementioned supports project from below.
    [0038] The safety device comprises a base support, consisting of a platform that can be coupled with a tribrach for surveying instruments, and electronic equipment, housed inside a housing that can be coupled to the support.
    [0040] The support consists of a preferred embodiment of the device in a disk-shaped plate, which comprises legs, which can be linked with the respective supports of the tribrach, a fixing element with the tribrach, and a housing for inserting the electronic equipment. , delimited by the aforementioned legs.
    [0042] It is also envisaged that the legs of the support have a through hole, in order to introduce through them additional security elements such as cables for physical anchoring with the instruments.
    [0044] The housing of the electronic equipment houses a GPS receiver, an accelerometer, a microcontroller and GPRS modem and a power supply battery, as well as the corresponding circuitry. Thus, any unwanted displacement of the topographic instruments in which the safety device is attached will involve the generation of a warning, preferably of an acoustic type, in which it is indicated that the instruments are being monitored, followed by a continuous beep or alarm signal. .
    [0046] Subsequently, a response is generated from the accelerometer, which will send a short warning SMS message with an Internet address to be able to proceed with the monitoring of the instruments.
    [0048] Since the housing with the internal electronic equipment is easily attachable and detachable from the support, once the instrument has been working and dismounted from the tripod and tribrach, said housing can be removed from the support to be inserted into a slot or housing the box or carrying case for said instruments, so that it would fulfill the same warning and monitoring function when the instrument is stored in the warehouse, construction site or transport vehicle.
    [0050] The surveying instrument security device thus described supposes a simple, economical and versatile solution, which avoids the aforementioned drawbacks and is applicable to any topographic instrument, regardless of its age or complexity.
    [0051] DESCRIPTION OF THE DRAWINGS
    [0053] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:
