Title: Pengcheng Dai: Innovator in Train Control Systems

Introduction

Pengcheng Dai is a notable inventor based in Nanjing, China. He has made significant contributions to the field of train control systems, holding 2 patents that enhance safety and efficiency in railway operations.

Latest Patents

One of his latest patents is a "Single-door control circuit for train." This innovative circuit includes a first circuit for controlling a single door when the train is in a sleep state, and a second circuit for controlling a door when the train is in a wake-up activated state. In the sleep state, the first circuit operates while the second circuit remains inactive. The door control unit is powered by a storage battery, and the single-door control is activated by an electric unlocking switch or a single-door button. Conversely, in the wake-up activated state, the first circuit is cut off, and the second circuit is energized, allowing the single-door control to be triggered only by activating the single-door button in the cab when the train is at zero velocity.

Another significant patent is the "Emergency braking control circuit based on coupler coupling detection." This circuit includes a coupler status detection circuit and a coupler status relay connected in series with the train power loop. When a coupler is coupled normally, inductive proximity sensors at the knuckle and central pivot drive the coupler status relay, ensuring that the emergency braking loop is closed. In the event of abnormal coupling or accidental uncoupling, the sensors disconnect, powering off the coupler status relays and applying emergency braking.
