Mounting bracket 4 is made a plate with the ends 31, respectively two lateral curved rounded edges 8 and has at least four longitudinal ribs 10 5.2 mm in height. The ribs 10 are oriented by the ends to the curved ends 31 of the plate and are located at a distance of 10-12 mm from each other from the side of the mounting panel 6. The mounting panel 6 is made with the cover 11 of the power compartment and with the cover 12 of the SIM card holder. The front panel 5, the mounting panel 6 and the cover 11 of the power compartment on the mounting panel 6 are connected by internal locking connections 15 with gaskets around the perimeter. The front panel 5 is equipped with optical fibers 13 of the signal LEDs 14 and is made with a flexible section in the form of a key 23 for interacting with an internal switch in the form of a button 24. The basic support elements 3 and mounting pads 2 are located for mounting the control unit board 22 with gaps between rounded 8 and flat side faces 9 of the front panel. The basic support elements 3 and installation sites 2 are made for installing the navigation receiver 16, the internal antenna GSM 17, the GSM modem 18, the internal antenna GLONASS 19, the cryptographic protection unit 25, the SIM card holder 12 and the tamper sensor 26 at the board 22 of the control unit with sides of the mounting panel 6 and for installing the switching voltage switch 27, the inductor 20 and the capacitors 21 at the control unit board 22 from the front panel 5 side.

In the particular case of its implementation or use, the housing 1 may include a mounting bracket 4, which is equipped with suction cups 28, and the mounting panel 6 is made with a protective protrusion 29 of the power cable 30 for connecting to the on-board network of the vehicle.

The on-board device for charging for the use of roads, made in housing 1, includes a user interface module with optical fibers 13 of the signal LEDs 14 on the front panel 5, a power supply module with an inductor 20, capacitors 21, a switching voltage switch 27 and a battery located in the power compartment, communication a module with a GSM modem 18 and an internal antenna GSM 17, a positioning module with a navigation receiver 16 and an internal antenna GLONASS 19, a module for monitoring the integrity of the housing with a sensor in covering of 26, SIM-card inserted in the holder, cryptographic protection unit 25, the control unit 22 with the card and a motion detector.

For operation, the on-board device can be mounted on suction cups 28 in the cab of, for example, a heavy vehicle.

The device is started by pressing on a flexible section of the housing 1, made in the form of a key 23, which transfers pressure to the internal switch in the form of a button 24 or automatically when a power supply is applied or a signal is received from the motion detector.

The glow of the signal LEDs 14 on the front panel 5 of the housing 1 indicates the readiness of the device for operation.

When the car is moving, the control unit (microcontroller with RAM, RPZU) controls the operation of all modules that are part of the on-board device. Built-in RAM is a memory intended for temporary storage of data and commands necessary for the microcontroller of the device to perform various operations. RPZU is used as a software carrier. A distinctive feature of RPZU microcircuits is their ability to repeatedly (up to 10 thousand) reprogramming.

The positioning module receives positioning data from GLONASS and GPS systems. This module defines:

- geographical latitude and longitude in the coordinate system P3-90.11;

- direction and speed of movement;

- time;

- accuracy parameters in horizontal and vertical planes;

- height;

- the number of satellites used;

- the number of visible satellites.

The communication module (wireless module - GSM / GPRS modem) supports data transmission over GSM networks of the frequency ranges GSM900, GSM1800, supports communications using GPRS services of class 10 and higher. To receive / transmit data by the specified module, the internal antenna of the GSM module is used.

The power supply module provides the possibility of power supply from the on-board network and ensures operability with the on-board network voltage of 10 V ^{+ 5%} _-15 % to 50 V ^{+ 5%} _-15% . In addition, it provides protection operation when the supply voltage exceeds 50 V ^{+ 5%} _-15% when the polarity of the connection is violated.

The battery provides the possibility of autonomous operation of the BU SVP-01 for at least 30 minutes in the absence of connection to the vehicle's on-board network, or its absence.

The power supply module monitors the battery charge and ensures that it is maintained at the desired level: the battery is put into charging mode if its charge level drops below 50% of the nominal one, it tracks the number of full battery charges for subsequent reading and monitoring.

The on-board device automatically switches to battery operation when the supply voltage is below 9 V, and vice versa, when the on-board power is connected, it switches to on-board operation.

A motion detector (accelerometer) measures the acceleration of the vehicle to convert these accelerations into a signal used to determine the parameters of its motion path.

The user interface module is used to inform the driver about operating modes, the state of the on-board device using visual indications (LED indicators) and sound (buzzer). The module also includes a mode control button.

The cryptographic protection unit implements cryptographic information conversion algorithms and provides registration of information in an unadjustable form in a protected memory, conversion of GLONASS signals into data on the current time and on the coordinates of the vehicle location in an unadjustable form.

In case of undesirable mechanical impact on the body of the on-board device, indicating an attempt to unauthorized access to its elements, the tamper sensor 26 of the module integrity control module provides an appropriate signal.

In case of accidental impact on the front panel 5 of the device, the housing 1 transfers the arising load to the mounting bracket 4 through longitudinal ribs 10 with a height of 2-5 mm, which are oriented by the ends to the curved ends 31 of the plate and are located at a distance of 10-12 mm from each other from the side of the mounting panel 6.

In the event of a device falling onto the cab floor, the mounting bracket 4 assumes the main shock load, since the part of the device with the mounting bracket 4 is its heavier part.
