technical characteristics

The NYJ 1 EMU is a hydraulic single-layer diesel EMU. The power cars at the front and rear ends of the EMU have the same structure, with a trailer in the middle. The standard grouping is two movements and four tows (Mc+4T+Mc), which can be adjusted according to users' needs. If it is extended to five or more trailers, the maximum speed of the train will be reduced. The front of the motor car is streamlined, and the car body has a low-height drum-shaped section. It also adopts electrically controlled pneumatic automatic plug door, sealed toughened glass window, fully sealed folding shed windshield, integrated glass fiber reinforced plastic toilet and toilet.

From front to back, the interior of the motor car is arranged in turn as driver's room, power room, cooling room, auxiliary power generation room, power distribution room and passenger room. The power room is equipped with a 3508B diesel engine with a load power of 1000kW, which is manufactured by Caterpillar Company of the United States. The transmission device is arranged in the cooling room, and adopts the same SF20 10 hydraulic transmission box as the Dongfanghong 3 diesel locomotive, and the cooling device, 33kW starting auxiliary generator and 22kW electric air pump set are arranged above it. Install a 200 kW auxiliary diesel generator set in the auxiliary generator room to supply power to the train air conditioning unit, electric heater, electric tea stove and lamps. The distribution room is equipped with auxiliary generator control panel, air conditioning control panel, charging device, fireworks alarm controller, fire extinguisher, shaft temperature alarm device, plug door centralized control device, etc. The rear of the bullet train is a passenger compartment with 38 seats.

The first and second motor cars are electrically reconnected by microcomputer, and their control systems are the same and interlocked with each other. The tail train control system receives the control instruction of the first train through the train communication network, and controls the whole train of the motor train at the same time. The monitoring information of the tail car can be displayed on the driver's desk of the head car through the communication network, and the driver can control the operation of the two motor cars on the head car. The train control and communication network system is based on the C805 1F040 microcontroller of Silicon Laboratory. The train communication network is divided into two levels according to TCN standard, and the 1 level is the wired train bus WTB, which realizes data communication between vehicles. The second level is the multi-function vehicle bus MVB, which mainly realizes the data communication between the functional control units in the same vehicle.
