Problems solved by technology
At present, the air source system of rail vehicles controls the automatic start and stop of the compressor through the pressure switch signal, but it is unable to monitor the status of the air source system, such as the wind capacity and compressed air quality. The corresponding state automatically starts the emergency treatment measures, which reduces the driving safety of the vehicle

The invention discloses a control device and method for a wind source system of a rail vehicle. The control method comprises the following steps: while a vehicle has power failure, automatically cutting off a main blast line by an electric-control cut-off valve, reducing leakage loss of total wind pressure, and reducing wind hitting time while the vehicle is activated next time; in a vehicle operation process, monitoring a dew point temperature of a dryer and a total wind pressure change rate of the main blast line in real time to realize monitoring on wind hitting ability of a compressor; while the dew point temperature is abnormal, switching to different dryers, compressors and even another air source system through an electric-control gas path switching mechanism, and guaranteeing quality of output compressed air; and while the total wind pressure change rate is abnormal, controlling the electric-control cut-off valve to act or simultaneously starting multiple sets of air source systems to guarantee sufficient supply of compressed air.
Description
technical field [0001] The invention belongs to the technical field of wind source system control, and in particular relates to a control device and method for a rail vehicle wind source system. Background technique [0002] Rail vehicles are equipped with an air source system to generate clean and dry compressed air, and the air source system is also used as the driving medium for the vehicle braking system and other air-using equipment (such as doors, kitchens, toilets, etc.). The brake system is an important subsystem related to the driving safety of the vehicle. The work of its key pneumatic valve components will affect the safe parking of the train. Therefore, the storage capacity and quality of the compressed air as the driving medium will have an important impact on the safe running of the train. At present, the air source system of rail vehicles controls the automatic start and stop of the compressor through the pressure switch signal, but it is unable to monitor the...
