Portion's circuit carries out high speed processing and communicates, and its operating temperature range is that-40 degree are to 105 degree.Panel is overall
Use PC104 bus structures, be used in real time, rapidly process brake switching value, analog quantity, network lead to
News data and brake information based data, it is achieved locomotive brake gear simulation and logic control, brake state
Monitoring and fault detect, diagnose, show, alert, the storage of data record, network communication, brake unit
The functions such as automatic test.
Brake controller use technical solutions of the utility model substitute traditional hard disk class storage with upper
Machine-readable take, material cost and time cost will be greatly reduced, utilize USB flash disk to obtain easily and be stored in
The data such as the daily record in flash memories 5, the human time that can reduce brake regular maintenance consumes, and improves
Efficiency, facilitates the reading of the data such as daily record, simultaneously.USB interface 4 can also be used to expand other in future
Function, it is also possible to the storage chip arranging in pairs or groups different uses.It addition, the daily vibrations of brake working environment are relatively big,
This utility model uses flash memories this welding class memorizer to add this scheme of USB interface unloading than tradition
