摘　　要：空电联合制动是一种新的制动技术。由于其工况和所需条件相对复杂,需要一种中继装置用于转化、记录变化的压力信号为易于传输、控制的电模拟信号,文章研究、设计了一种压差转换装置,该装置能精确用于电力机车空电联合时空气制动力信号控制电制动力大小。Electric-pneumatic blend brake is a new brake technology.Because of relatively complex working situation and required conditions,a relay device is required to transform and record the changeable pressure signal into an electric simulation signal which is easily to be transferred and controlled.This paper mainly studies and designs a pressure difference conversion device,which can accurately use air brake power signal to control brake power magnitude at the time of electric-pneumatic blend for electric locomotives.

关 键 词：空电联合 压差转换 列车管减压 可编程逻辑阵列
