In order to improve the detection efficiency and stability of auto-detection platform for train tail host, and reduce the instability of the system caused by frequent start-up of the electromagnetic valve, by the way of principle modeling, the basic nonlinear mathematic model structure was established for gas circuit control system of auto-detection platform for train tail host. The method of Least Squares Method (LSM) was used to identify modeling parameters. A new scheme based on precise calculation on gas circuit control system of auto-detection platform for train tail host was proposed. The performance of gas circuit control system was improved by this way, and the precision and stability was enhanced.
