Different vehicle speeds and different advancing directions of the rail vehicle in the advancing process can be simulated, so that the safety and reliability of circuits such as a corresponding sensor system and a feedback control system including a brake system or an alarm system in the rail vehicle can be tested.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle sensor system detection, and in particular relates to a rail vehicle speed simulation experiment device and a working condition simulation method. Background technique [0002] The traction control, braking force control, vehicle emergency braking, vehicle speed limit and door zero-speed protection function of rail vehicles and the judgment of special working conditions of the vehicle all need to be determined in combination with the vehicle speed. Speed ​​acquisition is the safety of the whole vehicle. One of the key factors of protection control, so it is particularly important to test the function of the speed sensor and the protection function under the special working conditions of the vehicle during the production and debugging of the vehicle. [0003] Metro vehicles generally use Hall-type sensors. Hall-type sensors can collect vehicle speed through non-contact measurement. When the ve...
