Description

Electronic bracelet of the monitoring system of controlled persons

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 an integrity system, 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 the lock and belts (see, for example, Equipment LLC IT corporation,.. htm I).

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 clasp, and an electrical detachable input of control signals (). 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 task 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, elastic belts, a lock, an integrity control system, a microcontroller connected to an autonomous power source, is configured to generate a signal and transmit an encoded signal , with a temperature sensor and a quartz resonator, is additionally equipped with a microcontroller with an RFID path and a tilt sensor, belts are made with closed collet connectors Mami and mortgages cable loop inside belt edge in places with a clamping body provided with swellings at an angle to the plane of the latter, with the castle built board with electrical contacts.

In addition, the housing is made of durable, hypoallergenic plastic.

In addition, the belts in the places of the thickenings are beveled and form a smooth arc with the body.

In addition, the belts are made of durable, hypoallergenic reinforced plastic with grooves for fixation, while on the outside of the belts there are transverse recesses for cutting the last necessary length.

In addition, the lock is made integral with the lock made integral with built-in electric knives, jumpers.

In addition, the bracelet integrity control system includes a case integrity sensor and a lock and belt control 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.

The EB contains: a sealed polymer housing 1 (Figs. 1-3, Pos. 1), elastic belts (Figs. 1-3, Pos. 2 and 3), a lock 5 with a sensor 16 for the integrity of the lock and belts (Fig. 5, pos. 16, Fig. 4, item 6, 7, 10). Case 1 can be made of durable, hypoallergenic reinforced plastic. Elastic belts with a flexible cable loop (Fig.1-3, pos.2 and 3) and a lock 5 with a sensor 16 integrity of the lock and belts (Fig.5 pos.16, Fig.4, pos.6, 7, 10) made of durable, hypoallergenic reinforced plastic to avoid skin irritation and other discomfort.

In a sealed polymer housing 1 (figure 5) are located:

a microcontroller 12 with a radio transmitter 13, a temperature sensor 14 and a quartz resonator (clock) 15;

- microcontroller 19 with RFID path;

- tilt sensor 18;

- sensor 17 integrity of the housing 1;

- autonomous power source 11.

Belts 2 and 3 are made at an angle to the plane of the housing 1 EB, closer to the housing, have a bevel and form a smooth arc with it (figure 2 pos.2). The design of the belts provides a more snug fit of the EB to the ankle or wrist of the controlled person, which reduces the number of attempts to remove the belts. Inside the belts 2 and 3, a cable (cable cable) with tinned copper conductors, in PVC insulation, a flexible and flat and closed collet detachable contacts for closing with the housing (Fig.3 pos.9) is laid. Belts 2 and 3 are made with grooves for fixing, while on the outside of the belts are applied transverse recesses for cutting the latter of the required length.

EB is a self-powered radio transmitter (Fig. 5, item 11), 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. 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 belts (Fig. 5, item 16). The integrity control of the electronic bracelet of the monitoring system of controlled persons comprises: a belt and lock integrity sensor 16, a housing integrity sensor 17.

Any attempt to cut or remove the belt triggers the sensor (Fig. 5, pos. 16) and generates a message on the server of the electronic monitoring system of controlled persons SEMPL.

A closed conductor-loop circuit is formed when the conductor-loop closes when the EB is worn.

Closed circuit in belts provide:

- cable loop inside belts 2 and 3;

- closed collet detachable contacts 9 for closing belts with the housing 1;

- lock 5 with integrated electric knives, jumpers 10 for closing belts.

The electric contact is provided by the upper 6 electric knives-jumpers 10 of the U-shaped form (2 pcs), which are built into the lock, for closing the belts, creating a closed "conductor-loop" circuit (Fig.3 pos.10). The electric jumper blades 10 are made of stainless sheet material with pointed ends.

The tilt sensor detects a change in the position (angle) of the EB (in a normal state, even if a person is sleeping, he turns).

If there is no change in position (angle) for a certain time, a message is transmitted to the SEMPL server, an alarm is generated, which is available to the criminal executive inspection officer (UII) (several options: CMC, information on a computer screen, etc.).

An electronic circuit uses an RFID path with an operating frequency of 125 kHz from NXP Semiconductors using the HITAG2 cryptography algorithm. The presence of the RFID path allows you to change the configuration 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 lock to access the contacts to remove the “alarm” signal, and does not require ensuring the corrosion resistance of the contacts.

Figure 4 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. 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 (the pin contacts embedded in the electronic housing are connected with detachable collet contacts to close the belts with the housing, creating a closed conductor-loop circuit (see remote element in FIG. .3). Fasten with two screws M3 × 8. 109.12 × 18H10T, GOST 17473-80 (see pos. 8 in figure 4). Locking of the screws is carried out with type EP51 paint. Install the belt 3 on the other side on the housing 1, aligning the contacts, protrusions with mating sockets.Fasten with two screws M3 × 8. 109.12 × 18H1 0T, GOST17473-80 and lock the screws with EP51 paint. The upper lock 6, the lower lock 7 and the locking device are completed with the product. Final assembly is done locally on the face under control by an IIDG officer. At the same time, put the EB on the wrist or ankle controlled by the person and fix the belts 2 and 3 in the guide grooves of the lower lock (see figure 4 pos.7). Combine the protrusions of the lock of the upper 6 with the mating slots of the lower lock 7 and use the device for locking the locks to snap the lock.

The work of electronic devices is as follows:

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 case and / or

a 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 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 belts, reliable electrical contact due to jumper blades for closing belts from the conductor, allows for enhanced functionality and reliable protection against access to electronic contacts due to the presence of the RFID path.
