Fig. 2 is locomotive parking brake applying method flow chart of the present invention.
Fig. 3 is locomotive parking brake remission method flow chart of the present invention.
Detailed description of the invention
In conjunction with accompanying drawing 1 to accompanying drawing 3, the present invention is described further, the locomotive parking brake control method of the present invention
As follows:
1) the gentle switching signal that solves of the applying of parking brake is controlled other than through hardware circuitry, passes through locomotive main simultaneously
Control microcomputer applies/alleviates instruction as instruction output end, output parking brake.
2) distance perspective induction sensor is increased between parking brake brake shoe and wheel pair, for judging applying or the alleviation of parking brake
State.Supplementing as parking brake reservoir pressure switch.
3) being controlled by locomotive main control microcomputer, when locomotive loads, no matter parking brake is in what state, all output is stopped
Put release of brake signal, and brake-cylinder pressure switch all represent with range sensor be in relieved state after can load.
4) realize the disconnected power supply that controls of locomotive and automatically apply parking brake function.
5) realize, when locomotive speed is more than 0km/h (this velocity amplitude can pass through software modification), not allowing applying to park system
Dynamic function.
Microcomputer judges that parking brake applies or relieved state, the most single dependence parking brake reservoir pressure switch, but
Judge that brake shoe and wheel are adjusted the distance sensor signal simultaneously, can decision state set up when two groups of signals are satisfied by requiring.
