前言意外紧急制动指示器是一种检测工具,用以辅助寻找引起意外紧急制动的制动管破损、制动软管未连接或者脱开或者其他引起空气制动装置紧急制动的原因。它通过检测首、尾车紧急制动状况并把信号传送到机车上,由机车确定和显示意外制动源的位置和原因。后端信号传送到机车上,是由无线电设备传送的(本文不叙述无线电设备);前端信号是由连接前车放风阀开关的电缆传送的。
Preface The Unexpected Emergency Brake Indicator is a test tool to assist in finding brake pipe damage that has caused unexpected emergency braking, the brake hose is not connected or disconnected, or other causes of an emergency brake on the air brake. By detecting the emergency braking status of the first and last car and transmitting the signal to the locomotive, the locomotive determines and displays the location and reason of the unexpected brake source. The back end signal is transmitted to the locomotive and is transmitted by the radio equipment (this article does not describe the radio equipment); the front end signal is transmitted by a cable that connects the switch of the front car vent valve.
