Description

Device and system for detection of radio signal Field of the invention

The invention relates to a device and a system for detection of a radio signal for the measurement, evaluation and analysis of the intensity of the radio signal for the purpose of early detection of an intruder in the guarded area.

Background of the invention

From the current state for the protection of areas there are used various types of fencing, combined with the electronic components of an attack signaling. Fencing is mainly made up of ioad-bearing structure such as pillars, which carries the fillers such as mesh, carrying also the electronic sensors and materials, which create a protective field. In the event of a intrusion of the protective field the alarm is triggered. It is known the solution according to the utility model CZ2800, whose essence is that the perimeter fencing consists of at least one row, while between the rows there is modified connecting field, where on the mesh each row has attached sensor cable sensing the vibration of the mesh. A substantial disadvantage of this solution is the need to surround the guarded space by the tensioning rods and pipes for placing of a sensor cable and also the high costs on the professional installation of cabling. Another disadvantage is also the interruption of the detection zone in the points of entry into the guarded object. Another significant disadvantage of this solution is the fact that the detection cable does not have long service life thanks to the action of UV radiation of the sun on this cable and after about 10-15 years has to be replaced due to its reduced sensitivity. The disadvantage of this solution is the fact that the detection cable in its length works as an unwanted antenna. In storm activity and atmospheric discharges it then brings up a very big risk of induction of the atmospheric energy into this cable, what results in the destruction of the control units directly connected to this cable. The disadvantage of the solution is also a very exacting repair of the system in case of intentional sabotage by cutting of the sensing cable.

Further, there are known the ways of guarding of a territory by using the special sensitive cables stored in the land around the fence, which detect an intruder on the principle of pressure, tremble and induction or magnetic changes. The disadvantage of this method of guarding a territory are the high costs for the preparatory works and works on the placing of the cabling and the very high costs of the technology itself. Another disadvantage is difficult overcoming of the territorial barriers such as roads, where there must be an interruption of the protective zone. This solution does not have 100% detection of the intruder, in the event that he comes through the detection zone through the layer of ice and frozen land under the ice. Again, the disadvantage of this solution is very exacting repair of the system in case of unintentional interruption of the cable in the land works going on the same estate.

There are known also the ways of guarding of the territory by using the sensors for a microwave barrier, where the sensors between each other detect the interruption of the microwave waves. The disadvantage of this solution are the demands of both the technical shield of the track of the waves, so to avoid their interruption, further the demands, that between the transmitting and receiving parts there cannot be in the vicinity the flat surfaces reflecting the microwave energy in the direction of their spread (such as a very smooth concrete surfaces, water level, etc.). A considerable disadvantage there are also high financial demands on the technology and its installation. This solution is entirely inappropriate for guarding the perimeter, which is adjustable in height and very often ragged.

Furthermore, it is known the solution with using the infra-latches, whose disadvantages relate both to the technical shield of infra-rays and ensuring a flat surface with no barriers between the particular sensors, and again in the high financial demands on the installation of the technology. Another disadvantage are the high demands on the need for the maintenance of the optical system of the infra- latches in clean condition. Strong disadvantage of this solution are the false alarms caused by the principle of the technology and the inability to properly detect the IR rays from the transmitting part of the infra-barrier in the case that into the optical system of the receiver the sun's rays of great intensity are directly hit. This solution is entirely inappropriate for guarding the perimeter, which is adjustable in height and very often ragged.

Furthermore, there is also known solution according to the application of the invention no. 2010-821 , whose essence is a way of protection of the guarded space using the RFID acceleration detectors so that at defined moments the hardware control unit activates the integrated vibration driver. This integrated vibration driver handles the response of the acceleration sensor, thereby performs the function control of the acceleration sensor and the active self-calibration RFID of the acceleration detector. In this way of the protection of the perimeter security using RFID acceleration detectors there happens a gradual synchronous transmission of data in a circle with the possibility of ignoring and reporting of the potential RFID of the acceieration detector in the failure and in the event of intrusion or sabotage with possibility to speed up the forwarding of the information to the nearest RFID monitoring unit, which will ensure the rotation of the camera to the place with the detection of intrusion or sabotage. The disadvantage of this solution is that the intruder must get in direct contact with the fencing part in such a way that fencing panel must by this contact get into the proper movement in order to activate the alarm system.

Summary of the invention

Mentioned disadvantages are removed by a device and system for the detection of a radio signal according to this invention, whose essence consists in the fact that it consists of at least two detectors, when each detector represents a separate module containing at least one communication unit providing the flow of radio signal, where the received intensity of the radio signal is evaluated by the integrated software component of the measurement of the intensity. The communication unit is also adapted for the transformation of data and communication with the data information. Further, the detector includes at least one hardware control unit, which is equipped with the integrated software component of the analysis and evaluation of data information.

It is appropriate that the communication unit and the hardware control unit were arranged together into a compact whoie. In the variant implementation the communication unit and the hardware control unit can be arranged as separate elements. It is advantageous that the communication unit is provided by an external and/or internal omnidirectional antenna for receiving and broadcasting an encoded radio signal.

It is also advisable to have the hardware control unit of at least one detector connected with external computer technology, which is equipped with compatible receiver of data information, while the transmission of the data information is provided by a communication unit. The external computer technology can take the form of a dedicated device, a personal computer, a tablet, a smart phone or other facility eligible for these purposes. In a convenient implementation the reciprocal link is wireless.

Furthermore, it is advisable to have the hardware control unit of at least one detector connected with the monitoring technology, which is equipped with compatible receiver of data information, while the transmission of the data information is provided by a communication unit. The monitoring technology can be preferably the industrial cameras or other tracking systems. In a convenient implementation the reciprocal link is wireless.

It is appropriate that each detector contains at least one measuring unit with at least one reclining sensor for detecting the position and/or at least one acceleration sensor for detection of impact and/or at least one thermal sensor for detecting the temperature and/or at least one acoustic sensor for detecting the sound.

It is also appropriate that the measuring unit is further affixed to at least one test element for detecting the current state of the sensors for the control of sensors and for self-control of the detection module.

It is advisable that the detector contains its own power source and/or was equipped with its own solar panel for power generation.

A substantial advantage of the device according to the present solution is that it allows the monitoring of the designated area, which is defined by the mutual distance between the two detectors that are mutually wlrelessly connected. In the case of an increase or decrease of the intensity of the radio signal outside the specified range, and by the evaluation and by the analysis of the changes in the intensity of the radio signal between the detectors, there can be detected the mere passive presence of an intruder in the monitored area, without causing the contact with an intruder, or of any person or animal entering into the guarded space with fencing panels.

Advantageously a device and system for the detection of a radio signal can be used for monitoring the perimeter, where the detectors are placed on the particular parts of the fence. Variant solution of the location of the detectors is on the roof of the guarded object or on the walls of the buildings, but also the placing directiy on the surface of the land.

An indisputable advantage of the device and system for the detection of a radio signal is its flexible use.

An indispensable advantage is completely accurate and targeted monitoring of the designated area with the possibility of regulation of the time interval of the broadcasting of the radio signal.

Other benefits of the device and system for detection of a radio signal can be seen in the simplicity of the structural arrangement and in the variability of its use for a wide variety of fencing kinds.

Examples of embodiment of the invention

Exemplary implementation of a device and a system for detection of a radio signal is realized so that it contains a system of two detectors 1 and 1², from which each represents a separate module. Each detector 1¹ and 1² of the system includes at least one communication unit 11 providing the flow of the radio signal, whose intensity is evaluated by the integrated software component 111 of the measurement of the intensity. The communication unit 11 is advantageously a radio module for radio- frequency broadcast in bidirectional flow. This communication unit 11 is also adapted for the transformation of data and communication with the data information. Detector 1¹ and 1² of the system further includes at least one hardware control unit 12, which is formed of a commercially available microprocessor. The hardware control unit 12 is provided with an integrated software component 121 of the analysis and evaluation of data information. In an advantageous implementation the communication unit 11 and the hardware control unit 12 are arranged in a compact unit. In variant implementation a communication unit 11 and the hardware control unit 12 may be arranged as separate elements. To ensure the flow of the radio signal the communication unit 11 includes an external and/or internal omnidirectional (or directional) antenna 13 for receiving and broadcasting an encoded radio signal. The internal antenna is advantageously a chip antenna or it is an antenna in the form of a motive on the printed circuit board. The external antenna is advantageously represented as the antenna emitter.

In an advantageous implementation the communication unit 11 of at least one of the detector 1¹ and/or 1² of the system is configured for communication with the receiver 21 of the data information computing technology 2. Computer technology 2 is in a convenient implementation in the form of visualization and/or communication elements (personal computer, smart phone, etc) with links to the usual means of information technology, e.g. for alarm signaling technology.

In an advantageous implementation the communication unit 11 of at least one of the detector 1¹ and/or ² of the system further communicates with the receiver of data information 31 of monitoring technologies 3. Monitoring technology 3 is in an advantageous implementation represented as the camera system and/or tracking system. in an advantageous implementation the device according to the above, each individual detector 1 and 1² of the system contains at least one measuring unit 14, which is provided with at least one reclining sensor 141 for detecting the position and/or with at least one acceleration sensor 142 for detecting the impact and/or with at least one thermal sensor 143 for detecting the temperature and/or with at least one acoustic sensor 144 for detecting the sound. Furthermore, the measuring unit 14 of the detector 1¹ and 1² of the system includes at least one test element 145 for detecting the current state of the sensors, for the control of sensors and for self- control of the detection module. In an advantageous implementation each detector 1¹ and 1² of the system includes its own power source 15 and/or its own soiar panel for power generation.

Detectors 1¹ and 1² of the device system and system for the detection of the radio signal are affixed to the fencing of the guarded area; most often this fencing is in the form of fence with fencing panels, and also areas of the roofs or walls of a building, etc.

The communication unit 11 of the detector 1¹ of the system at regular predetermined intervals sends out a radio signal. The communication unit 11 of the detector ² of the system receives a radio signal, and using the software components 111 of the measurement of the intensity the intensity of the radio signal is measured. This value of the intensity of the radio signal is by a communication unit 11 transformed into the data format and transmitted to the hardware control unit 12. Communication data transfer is realized by the standard way using the data bus.

The hardware control unit 12 of the detector 1 of the system using software components 121 analysis and evaluation of data information analyzes the received data and evaluates their status size. If the current size of the data is in the defined allowable range, which is operatively provided by the hardware control unit 12 of the detector 12 of the system, this situation is evaluated as a standard. The adopted value of the size of the intensity of the received radio signal is stored in memory of the hardware of the control unit 12 of the detector 1² of the system for the future determination of the defined permitted range of a radio signal. If the current size of the intensity of the radio signal is not in the defined allowable range, the situation is evaluated as alarming.

The hardware control unit 12 of the detector 1² of the system will send information to the communication unit 11 , and later it shall transmit the alarming report transformed into the desired format to the compatible receiver 21 of the data information computing technology 2, which indicates the alarming report by a standard way. At the same time, the communication unit 11 transmits the alarming report transformed into the desired format to the compatible receiver 31 of the data information of the monitoring technology 3.

Compatible receiver 21 and 31 of the data information is a communication interface, allowing working with the data information on the ordinary means of information technologies.

Monitoring technology 3, the most commonly as industrial camera, turns to the places, from where an alarm report was sent and the obtained image forwards to the computing technology 2, where the image is displayed the most commonly on the monitor of the personal computer, laptop or mobile phone.

Computer technology 2 evaluates the alarming report by the prescribed procedure.

In variant implementation it is possible to set the return flow of the radio signal, when after the receiving of the radio signal by the communication unit 11 of the detector 1², this communication unit 11 of the detector 1² sends a radio signal to the communication unit 1 of the detector 1¹, which receives this signal it and using the software components 1 1 of the measurement of the intensity the intensity of the radio signal is measured. This value of the intensity of the radio signal is by a communication unit 11 of the detector 1 transformed into the data format and transmitted to the hardware control unit 12 of the detector 1 . The hardware control unit 12 of the detector 1 by the use of software component 121 of the analysis and evaluation of data information analyzes the received data and evaluate their size. This return flow of the radio signal is the control of the basic receipt.

An exemplary implementation of a device and system for detection is the system containing the number of detectors 1 to 1^N. The communication unit 11 of the detector 1¹ of the system at regular predetermined intervals sends out a radio signal. This radio signal is received by the communication unit 11 of the detector ² of the system and it is received also by the communication unit 11 of the detector 1³ to 1 ^N of the system. The communication units 11 of the detectors 1² to 1^N of the system receive a radio signal and using software component 111 of the measurement of the intensity of the individual communication units 11 of the detectors 1² to 1^N of the system the intensity of the radio signal is measured. This value of the intensity of the radio signal is by a communication unit 11 of each of the detectors 1² to 1^N of the system transformed into the data format and transmitted to the relevant hardware control unit 12 of each of the detectors 1² to 1^N of the system. The hardware control unit 12 of the detectors 1² to 1^N of the system using software components 121 of the analysis and evaluation of data information analyzes the received data and evaluates their current value, and according to this size the situation, comparing according to defined parameters, is evaluated as standard or alarming, the next process is identical with the above mentioned.

The communication unit 11 of the detector 1² at regular predetermined intervals sends a radio signal to the communication unit 11 of the detector 1³ to 1^N of the system and at the same time in an advantageous implementation sends a backward radio signal to the communication unit 11 of the detector 1¹ of the system for receipt confirmation. Subsequently, the communication unit 11 of the detector 1³ of the system at regular predetermined intervals sends a radio signal to the communication unit 11 of the detector 1⁴ to 1^N of the system and at the same time in an advantageous implementation broadcast the backward radio signal to the communication unit 11 of detectors 1² to 1^N of the system for receipt confirmation.

The communication unit 11 of each of the detector 1¹ to 1^N of the system using software components 11 of the measurement of the intensity measures the intensity of the radio signal both in the basic direction, and in the advantageous implementation even in the backward direction of the radio flow. The value of the intensity of the radio signal is by a communication unit 11 of each of the detectors 1¹ to 1^N of the system transformed into the data format and transmitted to the hardware control unit 12 of the detectors 1¹ to 1 ^N of the system. The hardware control unit 12 of the detectors 1¹ to 1^N of the system using software components 131 of the analysis and evaluation of data information analyzes the received data and evaluates their current size. If this size is in in the defined allowable range, which is operatively provided by the hardware control unit 12 of the detectors 1¹ to 1^N of the system, this situation is evaluated as standard. Received state size of the intensity of the received radio signal is stored in memory of the hardware of the control unit 12 of the detectors 1¹ to 1^N of the system for the future determination of the defined permitted range of a radio signal. If received state size of the intensity of the radio signal is not in the defined allowable range, the situation is evaluated as alarming, next process is identical with the above mentioned.

This principle of transmitting and receiving a radio signal in the basic direction always to all and/or to only certain pre-specified, following communication units 11 of each detectors 1¹ to 1^N of the system in a row of and also in an advantageous implementation the backward confirmation to all individual and/or of the system secures both the maximum provision of the flow of the radio signal and also eliminates the signal failure or malfunction of a detector of the system in a row without it, that there was not ensured the flow of the radio signal, and thereby ensured the guarded area.

In the case of contact of an intruder with fencing panel there occur the shocks, vibrations or other mechanical influences, which are read by the measuring unit 14, which is provided with a reclining sensor 141 for detecting the position and/or acceleration sensor 142 for detecting the impact and/or thermal sensor 143 for detecting the temperature and/or acoustic sensor 144 for detecting the sound. The measuring unit 14 of each of the detector 1 to 1 ^N of the system contains at least one test element 145 for detecting the current state of the sensors, for the control of sensors and for self-control of the detection module. In an advantageous implementation of the detector 1¹ to 1^N of the system contains its own power source 15 and/or a solar panel.
