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 controlled persons, and can be used to monitor controlled persons, remotely identify and track their location.

The system of remote control of convicts in many countries has become a common punishment for small robbers, hooligans, car thieves, etc. The use of electronic tracking devices allows you to monitor controlled persons for 24 hours a day, which allowed it to be used to establish complete electronic control over the life of the convict during his stay under house arrest. In recent years, this type of punishment has become increasingly popular. In Sweden, those who are sentenced to sentences of up to 3 months can choose bracelets and total control at home instead of prison. Mostly this applies to petty thieves and drivers who have committed an accident. In Germany, the decision to transfer prisoners to electronic "house arrest" is taken by the prosecutor's office, mainly at the request of the convicts themselves. Moreover, not only those sentenced for short terms can choose bracelets, but also everyone who can count on parole. In Austria, since 2008, electronic anklets have been decided to wear on those on parole who were sentenced to up to 3 years. In the United States, electronic monitoring is used in 49 of the 50 states.

The prior art surveillance system for home arrest (see, for example, US patent No. 4918432, IPC G08B 29/04, publ. 04/17/1990), 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.

Also known is an electronic bracelet (hereinafter - EB), containing 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, lock with integrity sensor of the 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 housing, means for its fastening - a strap with a number of alternating holes, a clasp, and an electrical detachable 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, a means for attaching it, a lock, an integrity monitoring system connected to an autonomous power source, a microcontroller configured to generate a signal and transmit encoded signal, with a temperature sensor and a quartz resonator, is additionally equipped with a microcontroller with an RFID path and a three-axis position sensor of an electronic bracelet a, the means for attaching the case is made in the form of a sealed plastic belt equipped with a cable loop, eliminating removal without violating its structure, and electric jumper knives built into the case for closing the belt and creating a closed conductor-loop circuit, while at the base of the case for closing detachable collet contacts are located with latch latches, and holes are made coaxially last at the ends of the belt.

In addition, the body is made of durable, hypoallergenic plastic, and its base is made in an arc.

In addition, the belt is made of durable, hypoallergenic plastic, with trunnions corresponding to the holes in the base of the belt at the points of contact with the housing on the inside of the belt.

In addition, the electric jumper knives are ∐-shaped, made with pointed ends made of stainless sheet material.

In addition, the bracelet integrity monitoring system includes an unauthorized removal and tampering sensor and a belt integrity sensor.

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.

2. produce ultrasonic welding of the cover 3 with the base 8 of the housing 1 of the electronic bracelet.

3. check the tightness of the weld by the method of hydraulic testing.

Final assembly is carried out locally on a controlled entity by an IRUI employee. In order to put the EB on the ankle of a controlled person, two latches 4 are taken out of package No. 1, belt 2 of the required size from package No. 2 and:

4. install the belt pos.2 on one side on the base 8 of the housing 1 of the EB, while the pins 6 of the belt 2 should go into the holes pos.7 of the base of the housing 8 EB.

5. install the latch 4 on the belt 2, while the latches 21 of the latch 4 should go between the guide holes of the belt 2 and enter the collet detachable contacts 9.

6. squeeze the latch 4 and the belt 2 with the base of the bracelet body 8 to the stop.

A fixture for locking the latch and belt with the base of the housing is included in the scope of delivery of the electronic module.

Put EB on the ankle of the controlled person and repeat points 4, 5 and 6.

They check how the EB is worn, the reliability of its fastening and whether it causes discomfort to the person under control.

The work of electronic devices is as follows.

EB is a self-powered radio transmitter), which is mounted on the ankle of a controlled person. The EB emits an encoded signal that has a propagation range of up to 100 m in open space. After activation, 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 (over 6 hours).

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 EB is not used, the EB does not transmit any data, almost no autonomous power supply is 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.

The utility model provides a strong and reliable fastening due to a flexible cable loop inside the belt, reliable electrical contact due to jumper blades for closing the belt from the conductor, allows expansion of functionality and reliable protection against access to electronic contacts due to the presence of the RFID path. Compared with the known electronic devices, the design of the belt is simplified, due to its connection to the case of the bracelet, a board with collet contacts is excluded. In addition, the housing design is simplified by eliminating threaded metal fittings for screwing in screws, while eliminating the need to unscrew the screws securing the belt to the housing due to their absence.
