A BRAKE MONITORING DEVICE FOR RAILROAD CARS

摘要

A brake monitoring device for railroad cars is provided with a first comparison means which compares the electrical brake power equivalent signal with a first standard value, judges whether or not electrical brake power is generated and closes the locomotive brake deficit check circuit with an interlock means when such electrical brake power equivalent signal is smaller than such first standard value and which opens the locomotive brake deficit check circuit when it is larger. Such brake monitoring device also includes a second comparison means which compares the electrical brake power equivalent signal with a second standard value which judges whether or not electrical brake power is supplied to the brake power of the trailer car. Such device closes the trailer car brake deficit check circuit with such interlock means when the electrical brake power equivalent signal is smaller than the second standard value and opens the trailer car brake deficit check circuit when it is larger. Thus, in cases where brake power is not supplied to the trailer car, even if brake power is generated, it is still possible to greatly improve the safety and simplicity of the delayed-action control brake device.
