The technical result achieved by the implementation of the developed device is to increase the reliability of the security control system and communications of the passenger train by reducing the possibility of system failures due to interruptions in the power supply of the system and its individual nodes.

To achieve the specified technical result, it is proposed to use the developed Central Control System of the passenger train safety and communication control system. The developed Central Management System contains a metal case, inside of which are installed a mini-PBX motherboard, on which a DECT base station controller is installed, a cross-board with connectors for external connection to the mini-PBX motherboard interfaces, a metal platform is located above the motherboard, on which the PBX power supply, antenna heating board are located, a fuse is installed to protect the input circuitry of the antenna heating board, made with the possibility of at least two antennas are connected to the car’s electric power supply system, and the mini-PBX motherboard is connected to the antenna modules, the system telephone and the ACCH-2 unit via the cross-board, and at least two antenna antennas are connected to the central control system of the passenger train safety and communication control system modules, each of which contains two DECT base stations connected to the PBX motherboard, while the antenna modules are located on the roof of the car with the radio compartment and connected to the connectors of the PBX motherboard and the output time removing the antenna heating board installed on the case of the central control system of the passenger train safety and communication control system.

The developed system may additionally contain a UPN interface controller, capable of supporting up to 8 DECT base stations or other UPN-compatible devices, the UPN controller is connected to a group of two mini-PBX motherboard expansion pads. A group of two blocks is called a slot, so one UPN interface controller is connected to one slot of the PBX motherboard, and one slot consists of two blocks. Its use allows to increase the number of simultaneous connections of subscribers served.

The antenna heating board is preferably configured to heat at least two antenna modules containing metal bases, on which two DECT base stations are located, covered by a cover, which in turn is covered with a sealant, and also two heating elements, each of which is installed with the possibility of heating one of the DECT base stations at negative outside temperatures, and the DECT directional antenna, which is connected to the DECT base stations, with a thermostat placed inside each antenna module, moreover, the DECT base stations and the thermostat are configured to be connected to the central control system via cables and connectors installed on the basis of the antenna module, and the heating elements through the cable and connector installed on the basis of the antenna module, through the antenna heating board, which is located in the central control system are connected to the electric power supply system of the carriage, while the antenna module is closed by a radio-transparent cover.

The Central Control System (CSC), controlling the DECT base stations, emits the DECT signal along the entire length of the train through the DECT directional antennas. This supports the operability of all alarm relay devices (UPAS repeaters) and wearable DECT terminals of the train.

The UPAS repeater used is:

- receiving a DECT signal by means of an antenna connected to it and installed on the roof of the car, amplification and radiation of it inside the car;

- monitoring the hazard signaling button and existing car alarm systems, and if triggered, generating voice messages with their subsequent sending to the train crew by a certain algorithm;

- registration of the wearable terminal of the conductor in the Security and Communication Control System of the passenger train.

Each UPAS repeater has a dynamic registration (binding) in the central control center. The indicated function is implemented due to the ability to install various electronic registration keys in the UPAS repeater. Electronic registration keys are permanently registered in the NCC. Thus, depending on which central control center a set of magnetic keys will be used in such a headquarters car, specific UPAS repeater and wearable conductor terminal will be registered.
