Power supply is controlled, relay controls electromagnetism valve events, implements locomotive brake application.
The control method includes that locomotive parking brake applies control method and locomotive parking brake alleviation control method；
The locomotive parking brake apply control method the following steps are included: driver applied by parking brake switch to
Locomotive main control microcomputer issues parking brake and applies signal, and locomotive main control microcomputer judges locomotive speed signal, when locomotive speed
When spending V=0, after meeting parking brake application condition, output parking brake applies instruction, and electromagnetism valve events work as brake-cylinder pressure
Switch motion and brake shoe and wheel adjust the distance sensor when having signal output, and locomotive brake applies successfully, after locomotive shutdown, takes charge of
Machine-cut is broken locomotive control power, and parking brake applies automatically.
The locomotive parking brake alleviate control method the following steps are included: driver alleviated by parking brake switch to
Locomotive main control microcomputer issues parking brake mitigation signal, and output parking brake alleviates instruction, and electromagnetism valve events work as brake-cylinder pressure
Switch motion and brake shoe and wheel adjust the distance sensor when having signal output, and locomotive brake is alleviated successfully,
When locomotive main control microcomputer receives locomotive load instruction, microcomputer judges whether locomotive state meets loading environment, symbol
Conjunction then exports parking brake and alleviates instruction, and brake-cylinder pressure is switched after being in relieved state with range sensor and can be carried out
Load.
The beneficial effects of the present invention are: elevator car intelligent level can be in phase without manual operation
Parking brake is applied and alleviated automatically in the case where answering.Increase the decision condition of parking brake state, increasing locomotive can
By property.Perfect parking brake control logic reduces accident occurrence probability.
Detailed description of the invention
Fig. 1 is locomotive parking brake control system functional block diagram of the present invention.
Fig. 2 is locomotive parking brake applying method flow chart of the present invention.
Fig. 3 is that locomotive parking brake of the present invention alleviates method flow diagram.
Specific embodiment
Now in conjunction with attached drawing 1 to attached drawing 3, the present invention is described further, locomotive parking brake control method of the invention
It is as follows:
1) the gentle solution switching signal of the application of parking brake is controlled other than through hardware circuitry, while passing through locomotive master
Microcomputer is controlled as instruction output end, exports parking brake application/alleviation instruction.
2) increase between parking brake brake shoe and wheel pair apart from inductive pick-up, for judging the application or alleviation of parking brake
State.Supplement as parking brake cylinder pressure switch.
3) it is controlled by locomotive main control microcomputer, when locomotive load, no matter what state parking brake is in, and output stops
Release of brake signal is put, and brake-cylinder pressure switch indicates to be loaded after relieved state with range sensor.
4) realize that the disconnected control power supply of locomotive applies parking brake function automatically.
5) it realizes when locomotive speed is greater than 0km/h (velocity amplitude can pass through software modification), does not allow to apply the system of parking
Dynamic function.
Microcomputer judges parking brake application or relieved state, no longer single by parking brake cylinder pressure switch, but
Judge brake shoe simultaneously and wheel is adjusted the distance sensor signal, can determine that state is set up when two groups of signals, which are all satisfied, to be required.
Locomotive parking brake control system includes the following: parking brake application/alleviation switch, and brake shoe and wheel are adjusted the distance sensing
