Description

The utility model relates to electronic monitoring devices that provide the ability to search, detect, determine the current location and track the movements of moving ground objects, and is intended for monitoring controlled persons, remote individual identification and tracking of their location.

A new type of criminal punishment has appeared in Russia - “house arrest”, i.e. a ban on leaving the house or is allowed to be outside the house, but only in certain places and for a certain time (see article 107 of the Code of Criminal Procedure of the Russian Federation). The essence of house arrest is that if there are grounds for his election by court decision, the suspect (accused) is subject to restrictions related to the freedom of movement of the suspect (accused). Implementation of the norms of Article 107 of the Code of Criminal Procedure of the Russian Federation became possible after the introduction of such electronic tracking systems for the movements of a controlled person as an “electronic bracelet” (hereinafter - EB).

The practice of using EB has appeared in Western countries. Electronic surveillance of prisoners at home is particularly widespread in the United States. For many years, Americans sentenced to short sentences can ask the judge to replace them with jail with electronic “house arrest”. In this case, special EBs are put on them, periodically through the line (special devices, but the line is normal), to which an ordinary telephone can be connected or transmitting signals to the police station via a cellular communication channel. This allows you to control the stay of convicts at the place of residence at certain hours of the day, making it possible to leave the house only for the duration of the work.

From the prior art according to US patent No. 4918432, IPC G08B 29/04, published 04/17/1990 known surveillance system for home arrest containing an identification device mounted on a controlled person, and the identification device includes: a power source; a monitoring device (monitoring unit) for monitoring the set conditions, a transmitter for periodically transmitting data including information that uniquely identifies the monitoring device and environmental information received by the monitoring device, a receiver receiving signals from the transmitter of the monitoring device, and a processing unit data analyzing the data received from the monitoring device by determining the time of receipt of the periodic signal and identification information of the monitoring device containing Please refer to the data received by the receiver.

The known system does not allow to control the integrity of the control device (passive monitoring unit).

An EC is also known, which contains a sealed housing with a sensor for monitoring the unauthorized removal and opening of the latter, elastic belts with a system of their integrity, a microprocessor connected to the power supply unit, configured to generate a signal and transmit an encoded signal, with a temperature sensor and a quartz resonator, a lock with an integrity sensor a lock and belts (see, for example, Equipment of IT Corporation LLC, http://www.itcrp.ru/advanced.html).

The closest to the claimed utility model in terms of technical nature and the technical result achieved by using the utility model is an Elmo-Tech electronic module containing a case, a strap with a number of alternating holes, a fastener and detachable electrical input of control signals (http: //www.elmotech. com / default). The control strap has two collet connectors for connecting the conductors of the strap to the transmitter body, equipped with a pair of pin contacts for inputting electrical control signals. The transmitter mounting strap consists of two parts, each of which contains a pair of conductors made in the form of a flexible printed circuit board, to the current-carrying parts of which collet detachable contacts are soldered on one side to connect to the contacts of the electrical input signals of the housing, and on the other hand, one of the parts strap - pin contacts for connecting a fastener containing an electric jumper. The conductors of the other part of the strap, equipped with holes, form a closed half-loop in the form of printed conductors connected to the collet connectors of the contacts for connection to the transmitter body. The clasp of the strap is made in the form of two interlocking parts with a pair of coaxially located pin guides and receiving holes, as well as an electric jumper for the pin contacts of the first part of the strap, made of conductive rubber in the form of cylindrical cavities worn on the pins when the two parts of the clasp are closed along the coaxial guides.

When operating a well-known electronic device and immersing a strap with a fastener in sea water or exposing detergents to a controlled person, the contact resistance of pins and conductive rubber irrevocably increases (from tens of ohms to 1000 ohms in nominal) and leads to a false triggering of the removal control system (unfastening) of the strap .

Another disadvantage of the known electronic device is the low security of the design of the straps from unauthorized removal of the bracelet by bridging the signal conductors in the body of the straps with a pair of sharp (thin) needles connected by an electrical conductor and blocking the signals in both parts of the straps, which allows you to unfasten the clasp or cut the second part of the strap to remove EB from the suspect’s arm or leg.

The task underlying this utility model is to create an electronic circuit free from the indicated drawbacks inherent in technical solutions representing the prior art, and to ensure the integrity control of electronic batteries.

The problem underlying this utility model is solved by the fact that the electronic bracelet of the monitoring system of controlled persons, containing a sealed polymer case with a sensor for monitoring the unauthorized removal and opening of the latter, elastic belts and a lock with an integrity control system, connected to an autonomous power source microcontroller, made with the ability to generate a signal and transmit an encoded signal, with a temperature sensor and a quartz resonator, it is additionally equipped with a microcontroller RFID triaxial tract and position sensor belts are made with closed collet detachable contacts and a metal plate inside the mortgage, wherein a locking plug inserted with a bridge from the conductor.

In addition, the belts are made of durable, hypoallergenic reinforced plastic with round or square holes.

The presence of the RFID path allows you to change the configuration or change the operating mode without removing the electronic components, changing the electronic software without opening the case, provides high cryptographic strength (software) of the electronic components, does not require breaking the latch to access the contacts to remove the “alarm” signal, and does not require corrosion resistance contacts.

The proposed utility model allows to maintain safety for the health of the controlled person, to exclude the possibility of uncontrolled removal and opening, and to be relatively inexpensive to manufacture and maintain.

A comparative analysis of the proposed technical solution with identified analogues of the prior art, from which the utility model does not explicitly follow for a specialist in the field of electronic monitoring, showed that it is not known, and taking into account the possibility of industrial serial production of an electronic bracelet for a monitoring system of controlled persons, it is possible to make Conclusion of eligibility for patentability.

EB is a self-powered radio transmitter (Fig.4 pos.13), which is mounted on the ankle or wrist of a controlled person. The EB emits an encoded signal that has a propagation range of up to 100 m in open space. Elastic belts (Fig. 3, Pos. 2, 3) and a lock with an integrity sensor (Fig. 4, Pos. 19, Fig. 3, Pos. 6, 7, 10) are made of durable, hypoallergenic reinforced plastic, which avoids skin irritation and other discomfort.

EB is designed to be worn continuously and is specially designed to achieve maximum structural strength. EB is completely tight and waterproof.

To prevent unauthorized removal, the EC has an integrity sensor for the lock and belt (Fig. 4, pos. 19). Any attempt to cut or remove the belt will trigger the sensor (Fig. 4, item 19) and generate a message on the server of the electronic monitoring system of controlled persons (SEMPL).

The electronic circuit contains: a sealed polymer case (Fig. 4, Fig. 3, pos. 1), elastic belts (Fig. 3, pos. 2, 3), a lock with an integrity sensor for the lock and belts (Fig. 4, pos. 19, Fig. 3 , pos. 6, 7, 10).

The presence of the RFID path allows you to change the configuration or change the operating mode without removing the electronic components, changing the electronic software without opening the case, provides high cryptographic strength (software) of the electronic components, does not require breaking the latch to access the contacts to remove the “alarm” signal, and does not require corrosion resistance , the second microcontroller does not require power for the RFID path to work, it is possible to uniquely identify the bracelet in case of power failure of the first microcontroller.

Figure 3 shows the sequence of Assembly of the EB, which includes the following steps.

A cover 4 is mounted on the housing 1 with the soldered EB circuit board, then the seam of the housing 1 and the cover 4 is sealed around the perimeter by ultrasonic welding. Install the belt 2 on one side of the housing 1, aligning the contacts, the tabs with the mating sockets. Install the clamp 11 on the belt 2 in the place of application to the housing 1, fix it with two screws M3 × 8 pos.12 and lock the screws with EP51 paint. Install the belt 3 on the other hand on the housing 1, aligning the contacts, the tabs with the mating sockets. Install the clamp 11 on the belt 3 in the place of application to the housing 1, fix it with two screws M3 × 8 pos.12 and lock the screws with EP51 paint. The upper lock pos.6, the lower lock pos.8, the plug pos.10 and the locking device are completed in the delivery of the product. Final assembly is carried out locally on a controlled entity by an IRUI employee (see FIGS. 5 and 6). In this case, an EB is installed on the wrist or ankle of a controlled person. Fix the short belt 2 first using the lower lock 7, then install the long belt 3 in the guide bushings of the lower lock 7. Insert the plug 10 into the collet holes of the short belt 2. Using the locking device, lock the lock 5. This forms a closed chain "conductor -the loop". A closed circuit in belts 2 and 3 is provided by: a metal embedded plate inside the belts, closed collet detachable contacts 9 and a lock 5 with an integrated plug 10 with an electric jumper from the conductor.

The operation of electronic electronic devices is as follows.

In the initial state, the bracelet does not emit signals over the air. To transfer the radio telegrams to the radiation mode, it is necessary to send the appropriate command through the RFID path. After turning on the radiation, it is necessary to adjust the range of the bracelet, through the RFID path the bracelet is transferred to a special mode in which it is convenient to adjust the sensitivity of the control system (ElmoTech does not have this mode. Usually, only after this the bracelet is put into the regular active mode of operation.

In active mode, the EB continuously radiates signals over the radio channel to the control device (KU). The radio signal contains a permanent tag protected from counterfeiting; including:

- individual unique identification number of electronic books;

- information about the condition of the housing of its transmitter, the integrity of the belt and its fastening;

- information about the absence / presence of attempts to break into the housing and / or belt;

- information about the status of the power source;

- information on the duration of the EB in the on state;

- information about the absence / presence of errors in the firmware;

- information about the prolonged, at the discretion of the relevant official, lack of movement of a controlled person with electronic gear worn.

The electronic signal transmits a radio frequency signal containing messages that include information about the serial number of the bracelet and the electronic state - the current voltage of the autonomous power source, electronic temperature and the following alarm statuses:

- violation of the integrity of the EB belt;

- violation of the integrity of the electronic housing;

- discharge of an autonomous power supply of electronic devices;

- prolonged lack of movement of a controlled person with a worn EB (more than 6 hours);

- restarting the electronic program.

The EB transmits information about the emergency state of the power source at least 72 hours before it is turned off.

To save battery power, it is possible to transfer the EB to a mode in which it does not emit a radio signal for a time when it is not in use.

If the controlled person is absent in the specified area for a certain time, KU records the absence of the EB signal and writes the fact of the absence of the controlled person in its internal memory as an event. When KU determines the fact that there is no controlled entity, it connects to the SEMPL server and transmits information about the event to the server. The data is analyzed on the server, the alarm level is determined and further actions are formed according to the service regulations.

EB has the following operating modes:

1) “Off” (sleep mode) - a mode in which the electronic power supply is not used, the electronic transmission system does not transmit any data, the autonomous power supply is almost not used;

2) “On” (active mode) - in this mode, the electronic control unit controls the movement of the controlled person and regularly transmits signals with information to the control unit.

3) “Test” - the EB mode used during initial installation in the zone of control of movement of a controlled person. In this mode, the power of the EB signal received in the control unit is calibrated. This allows you to correctly configure the boundaries of the controlled movement zone and configure the reception of radio signals in the control unit. If the EB is in the “Test” mode, then the control unit does not save any events about the movement of the controlled person. In the "Test" mode, the EB transmits a signal at intervals convenient for tuning. The “Test” mode lasts for a “time of sufficient adjustment” and can be terminated forcibly or automatically at the end of a certain time, then the electronic switch automatically switches to the “Off” mode. In the "Test" mode, if the control unit is in the "Deactivated" mode, it will emit sound signals that confirm the reception of signals from the electronic control unit.

If the person under control tries to remove the electronic device (for example, cut the strap or destroy the electronic case), the electronic device immediately transmits a signal containing the highest priority event. This instructs the control unit to immediately connect to the SAMPL server, creating an alarming warning (attempt to remove the bracelet). This warning is shown in the SAMPL software as a warning of the highest or critical level.

This utility model is industrially applicable, since its implementation is designed to use remote access networks and RFID technology, which today is a well-established means.

The utility model provides a strong and reliable fastening due to a metal embedded plate inside the belt, reliable electrical contact due to a jumper from the conductor, allows enhanced functionality and reliable protection against access to electronic contacts due to the presence of the RFID path.
