Abstract

The invention discloses a monitoring device of an air source system dryer. The monitoring device comprises a dryer monitoring module, a master control module and an air compressor control module, wherein the dryer monitoring module outputs desiccant state signals, drainage valve state signals and power state signals of the dryer; the master control module is connected with the dryer monitoring module, receives the desiccant state signals, the drainage valve state signals and the power state signals and gives out an air compressor start-stop instruction after judging that one or more of the desiccant state signals, the drainage valve state signals and the power state signals are abnormal; the air compressor control module is connected with the master control module and controls an air compressor to stop operating when receiving the air compressor start-stop instruction. By means of the monitoring device of the air source system dryer, real-time monitoring of the work state of the dryer in an air source system is achieved, the air source system can be timely controlled to be stopped when the dryer is monitored to be abnormal in the work state or stop working, and affection of normal operation of a locomotive brake system is avoided.

Description

technical field [0001] The invention relates to the technical field of locomotive braking, in particular to a monitoring device for a dryer of an air source system. Background technique [0002] The air source system of a locomotive is a component that provides an air source for the braking system of the locomotive. The safety, reliability and stability of the air source system are particularly important. If there are hidden dangers, it will pose a serious threat to the safe operation of the locomotive. [0003] In the locomotive air source system, a dryer is used to dry and purify the compressed air to ensure that dry and clean compressed air is provided to the locomotive braking system. In the prior art, the dryer in the air source system is openly controlled, that is, the locomotive control system cannot monitor the working status of the dryer, so when the dryer is in abnormal working status or stops working, the dryer cannot effectively Dry and clean the compressed air,...
