Latest Patents

One of Meng Shi's latest patents is a parking brake control method for an electromechanical brake system of urban rail vehicles. This method includes an operation instruction mechanism, a brake control mechanism, an electromechanical actuating mechanism, and an auxiliary mechanism. The operation instruction mechanism outputs a control signal to the brake control mechanism, driving the action of the electromechanical actuating mechanism to achieve braking application and relief of the vehicle. The auxiliary mechanism serves as a redundant power supply system for the brake system, featuring a zero-speed state monitoring mechanism and an energy storage battery mechanism for backup power supply. This innovative method allows urban rail vehicles to achieve brake application and relief in both parked and dormant states.

Another significant patent by Meng Shi is a vehicle body contour-based derailment detection method for rail vehicles. This method involves measuring distances between measuring points and rails using a range finder mounted on the vehicle's underframe. It calculates the transverse displacement of the vehicle body and measures its inclination angle through an inclination sensor. By referencing the vehicle body size and measuring point distribution, the method obtains a dynamic outer contour of the vehicle body, converting it into a dynamic outer contour in the rail coordinate system. This invention enhances the safety of rail vehicles by providing a reliable derailment detection mechanism.
