Problems solved by technology
When the wheel rubs against the brake shoe, the temperature of the wheel and the brake shoe will increase, and the surface of the brake shoe friction block will be worn. When the friction block wears to a certain extent, if the brake shoe cannot be replaced in time, it will bring great harm to the train security risks
[0003] At present, the degree of wear of train brake shoes is determined by drawing lines on the friction blocks. When the train stops, manual observation is used to check whether the brake shoes need to be replaced, which is not only time-consuming and laborious, but also has visual errors. Cause waste of friction blocks or potential safety hazards

The invention provides a train brake shoe abrasion detection device which comprises a brake shoe abrasion detection electronic tag installed on a train brake shoe as well as an RFID reader-writer anda ground train monitoring system which are installed on the ground, wherein the brake shoe abrasion detection electronic tag detects the abrasion degree of a brake shoe friction block by detecting thechange of the thickness of the brake shoe friction block and transmits a detection result to the RFID reader-writer in a wireless transmission mode, and the RFID reader-writer is connected with the ground train monitoring system. The invention further provides a train brake shoe abrasion detection method. The train brake shoe abrasion detection system and method have the beneficial effects that the train brake shoe abrasion condition can be monitored in real time, the brake shoe with the life cycle completed is replaced in time, compared with manual visual brake shoe abrasion inspection, theefficiency of workers is improved, visual errors are prevented, automatic train brake shoe abrasion inspection management and brake shoe replacement traceability management are achieved, brake shoe waste is reduced, the train operation safety is improved, and the operation cost is reduced.
Description
technical field [0001] The invention relates to a train brake shoe, in particular to a train brake shoe wear detection device and a detection method. Background technique [0002] The brake shoe is a brake part that directly rubs against the wheel to stop the train when the train is running and braking. It is a tile-shaped brake block made of cast iron or other materials. Friction between the wheels stops the wheels from turning. When the wheel rubs against the brake shoe, the temperature of the wheel and the brake shoe will increase, and the surface of the brake shoe friction block will be worn. When the friction block wears to a certain extent, if the brake shoe cannot be replaced in time, it will bring great harm to the train security risks. [0003] At present, the degree of wear of train brake shoes is determined by drawing lines on the friction blocks. When the train stops, manual observation is used to check whether the brake shoes need to be replaced. This is not o...
