Latest Patents
One of his latest patents is the "Emergency braking extension device for urban rail vehicle." This device includes an emergency braking extension loop, a first emergency braking extension train line, and a second emergency braking extension train line. The emergency braking extension loop features a protective circuit breaker, a normally open contact of an emergency braking button, and an emergency braking extension relay, all connected in series. Additionally, a normally open contact of the emergency braking extension relay is linked to a pantograph lowering control loop. The device also incorporates normally closed contacts connected to the return line and power supply negative loop of a train emergency braking control loop, enhancing the overall safety of urban rail vehicles.
Another significant patent is the "Vehicle body contour-based derailment detection method for rail vehicle." This method involves measuring distances between measuring points and rails using a range finder mounted on the underframe of a vehicle body. It calculates the transverse displacement of the vehicle body in a coordinate system and measures the inclination angle through an inclination sensor. By referencing the size of the vehicle body and the distribution positions of the measuring points, the method obtains a dynamic outer contour of the vehicle body, which is crucial for ensuring safety and preventing derailments.
