The disadvantages of the known solution is the complexity of removing the CIPF block, as well as the inability to replace the CIPF block not in a specialized workshop, but by the end user of the tachograph.

The objective of the patented solution is to eliminate the shortcomings of the known solutions.

The technical result of the utility model is to increase the reliability of the tachograph design, reduce the time and simplify the replacement of the CIPF unit with the NKM of the tachograph by the user without removing the tachograph from the installation site, with the exception of unauthorized replacement of the CIPF unit with the NKM of the tachograph, and increasing the accuracy of the transmitted data.

The technical result is achieved when using a tachograph with an CIPF block with NCM, containing a housing, inside of which are placed:

- a central processing unit configured to provide tachograph functions,

- an additional processor designed to interact with the central processor and provide the functions of a telematics unit: data transfer, voice communication, connection of additional equipment,

- installation board for the CIPF block with NKM and a connector for connecting NKM to the tachograph and GPS / GLONASS antenna,

- modem for remote data and voice communication

- external power supply,

- an internal power supply, made with the possibility of control through the central processor,

- as well as input device, display, card reader, printer,

at the same time, the board with the CIPF block with NCM is installed in the compartment, in which the sensor for the presence of the CIPF block board is installed and closed by a lid, made with the possibility of its automatic opening/closing by an electrically controlled latch with the possibility of control by means of the input device and the central processor.

Ease of replacing the CIPF unit by the user is achieved through the use of an electrically controlled latch and the presence of a board on which a connector for the CIPF unit with NCM and connectors for connecting the CIPF to the tachograph and GPS/GLONASS antenna is installed. An electrically controlled latch allows access to the compartment with the CIPF block board with NCM after the tachograph is switched to the state of replacing the CIPF unit with NCM, while the connection of the CIPF unit board with NCM to the tachograph connectors and the GPS / GLONASS antenna occurs automatically when the board with the CIPF unit is installed ( NKM) into the tachograph housing to the working position. When the board is removed from the tachograph, it is automatically disconnected from the connectors, and the sensor for the presence of the board of the cryptographic information protection unit with NKM is also triggered. In case of activation of the sensor for the presence of the CIPF block board (NKM), the tachograph detects the removal of the CIPF block from the tachograph. If the tachograph is in the CIPF replacement state, then it is considered that an authorized replacement of the NKM is taking place. If the tachograph is not in the CIPF replacement state, then an attempt of unauthorized CIPF replacement is recorded.

The patented solution makes it possible to replace the CIPF with NKM without the need to remove the tachograph from the car, there is no need to disassemble the elements of the tachograph case and manually connect/disconnect the CIPF (NKM) connectors. This leads to a decrease in the likelihood of damage to the elements of the tachograph and the CIPF (NKM), and also allows for authorized replacement of the CIPF (NKM) by less qualified personnel.

Thus, there is a simplification of the replacement of the CIPF unit with the NCM, a reduction in the replacement time, and also to exclude damage to the tachograph when replacing the unit, even by personnel without special training.

Due to the presence of external and internal power supplies, uninterrupted operation and constant data transfer are ensured.
