AI Technical Summary
Technical Problem
The existing platform clearance compensators and door systems of rail vehicles are nested together, making it impossible to control them independently, which increases costs.
Method used
A clearance compensator with extension and retraction functions and a corresponding control air circuit are installed on the platform. The control system, consisting of a cylinder block, cylinder rod, reversing valve and sensor, enables independent control of each clearance compensator.
Benefits of technology
Independent control of each gap compensator was achieved, reducing costs and ensuring passenger safety and equipment integrity.

Abstract
This invention provides a control system for a clearance compensator, a rail vehicle, and a control method for the rail vehicle. The control system includes: a cylinder body, a cylinder rod, a reversing valve, and a sensor. The cylinder rod is retractably mounted within the cylinder body. The free end of the cylinder rod is connected to the door clearance compensator of the rail vehicle. The reversing valve is connected to both the cylinder body and the main air duct of the rail vehicle. The sensor is positioned along the path connecting the reversing valve and the cylinder body. The sensor is connected to the rail vehicle's control network to provide feedback on the air pressure value along the path. This invention achieves clearance compensation between platforms by installing clearance compensators with extension and retraction functions and corresponding control air paths at the platforms, ensuring independent control of each clearance compensator and significantly reducing costs.
