System Introduction

It adopts microcomputer control technology, collects vehicle digital signals and receives communication instructions, performs logical operations, and transmits control instructions to the input and output board through the bus channel to control and drive vehicle-related control circuits, low-voltage switch devices, microcomputer units and other external interface objects. It realizes vehicle power supply, traction, braking, door and other functions. It is used to replace the hard-wired relay circuit in train control and realize the corresponding logical control function.
