During the search in the scientific, technical and patent literature, no source of information was identified that characterizes the testing tool of the above passenger safety and communication control system (SKBiSPP).

The technical problem solved by the proposed developed complex is to develop a device that provides monitoring of SKBiSPP.

The technical result obtained by the implementation of the proposed complex is to increase the safety of operation of the passenger train by providing the possibility of objective control of the elements of SKBiSPP.

To obtain the specified technical result, it is proposed to use a mobile measuring complex of the developed composition. The mobile measuring complex contains a test module and auxiliary equipment, the test module comprising a central control system, at least three wearable terminals, at least two Huber + suhner pin antennas, at least three electronic registration keys and a network power cable, and the auxiliary equipment includes a small-sized electric generator, a power supply module and an extension cord on the reel.

Preferably, the module and accessories are housed in shockproof, waterproof cases.

The test module is preferably a sealed high-strength case, inside which a central control system, a DECT base station, two whip antennas of the Huber + suhner type, a charger for three wearable terminals and three electronic registration keys are installed.

The central control system (NCC), made on the basis of a microprocessor, combines the functions of switching equipment and connection control devices in SKBiSPP. A DECT base station and a charger for three wearable terminals are connected to the DCC. The central control center supplies power from an external power source through a power cable with a 2PM14 connector. The base station is designed to organize DECT standard radio channels with subscriber devices.

The whip antenna is designed to receive and transmit DECT standard radio signals in the range from 1880 to 1900 MHz. The wearable terminal (hereinafter referred to as NT) is made on the basis of a microprocessor and is designed to connect the subscriber via a radio channel to the central control center. The NT of the train chief, train electrician, police officer is charged from one triple charger. All NTs are shockproof, dustproof, and waterproof.

An electronic registration key (ECR) is a device designed to register an alarm transmission device — a repeater (UPAS repeater) and an NT conductor of the tested car in a mobile test complex (MIC). ECRs have serial numbers 1, 2, and 3. The base station and the charger for the three wearable terminals receive power from the DCC.

As an auxiliary equipment, a HONDA EU10i type electric generator is usually used: power 1 kW, power supply module in a portable suitcase-container: 220 V AC / 110 (55) V DC, 600 W with an interference suppression filter and an outlet block, extension cord on a coil 25 m, as well as a network power cable P1 and a network power cable P2.

The test module used must comply with the following technical specifications:

The standard for the base station and wearable terminals is DECT / GAP. The operating frequency range of wearable terminals and the base station is from 1880 to 1900 MHz. The gain of the whip antenna is at least 3 dB. The polarization of the whip antenna is vertical. The impedance of the antenna-feeder path is 50 Ohms. The rated radiated power of DECT devices is not more than 10 mW. The communication range between the test module and the wearable terminal is up to 300 m with direct visibility. The communication range between the test module and the SKB and SPP equipment installed in the service compartment of the conductor is up to 300 m subject to direct visibility.

Power Supply:

- from a direct current source with voltage from 75 to 150 V.

- from an alternating current source (50-60 Hz) with voltage from 100 to 240 V.

- from the on-board network of the car with a voltage of 110 V. Power consumption - no more than 100 watts. The wearable terminal is powered by an internal Ni-Mn rechargeable battery with a capacity of 650 mA / h, which provides talk time for 8 hours and standby time up to 75 hours. The time of a full charge of the battery is no more than 4 hours.

The number of simultaneously checked sets of SKB and SPP equipment installed in the service compartment of cars does not exceed three. The operating time, without connecting to the power supply, is determined by the time of continuous operation of the generator. Operating time from external networks 110 V and 220 V is not limited.

As indicated earlier, the MIC is designed to test the operability of the equipment of the SKB and SPP system of the service compartment of the conductor. During the work of the MIC, it is ensured that the head of the train, train electrician and the transport police officer receive voice messages about emergency situations in the tested cars, as well as checking the internal communication. MIK allows the simultaneous verification of SKB and SPP equipment of three train cars. Verification of the arrival of voice alarm messages is carried out by initiating an emergency in the checked car. Verification of internal communication consists in establishing radio communication between the wearable terminal of the car conductor and the wearable terminals of the MIC.

Using the developed mobile measuring complex allows you to check the operation of SKBiSPP in the conditions of finding wagons equipped with the specified system in the depot and in the absence of power supply wagons.
