Example Embodiment

[0025] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] The hydrogen safety control system for hydrogen fuel cell bus of the present invention is such as figure 1 Shown:

[0027] The hydrogen system controller, fuel cell controller, and vehicle controller simultaneously monitor the safety status of the vehicle in real time; moreover, the hydrogen system controller, fuel cell controller, vehicle controller and instrumentation communicate through the CAN network. Among them, the hydrogen system controller is connected with concentration, pressure, and temperature sensors, and mainly monitors the temperature and pressure of the bottle mouth of the hydrogen storage bottle and the concentration of hydrogen in the area that is likely to cause hydrogen leakage; the output of the vehicle controller and the collision sensor is connected through a hard wire, The status signal of the proximity s...

Abstract

The invention provides a hydrogen safety control method and system for a hydrogen fuel cell bus. Under the situation that a vehicle control unit monitors that the bus does not have severe alarm information, a hydrogen system controller monitors that a hydrogen storage bottle is in a normal state and a fuel cell controller monitors that a fuel cell is in a normal state, operation of a hydrogen bottleneck electromagnetic valve is unlocked and is locked otherwise. According to the hydrogen safety control method and system for the hydrogen fuel cell bus, active safety of a fuel cell bus system isstrengthened while relative national standard requirements of the safety of a hydrogen system of the fuel cell bus are met.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel cell buses, and in particular relates to a hydrogen safety control method and system for hydrogen fuel cell buses. Background technique [0002] At present, hydrogen fuel cell vehicles are favored by major automakers for their short refueling time, high driving range, zero pollution and many other outstanding advantages, and they have stepped up research and development efforts. In the field of buses, hydrogen fuel cell buses are becoming the mainstream development direction of new energy buses in the future. [0003] However, compared with the existing new energy buses (pure electric buses, plug-in hybrid vehicles, etc.), the national standard "GB / T24549-2009 Safety Requirements for Fuel Cell Electric Vehicles" has special requirements for fuel cell vehicles, including: fuel filling : The vehicle fuel system should include a function that can cut off the fuel supply to the fuel cell system...
