In order to more clearly describe implementation of the invention, the present invention also provides a kind of automatic drain valve control method,
As shown in Fig. 2 including：
Step 101, after receiving air compressor machine startup control command, controls the normally opened contact 1-2 of drain knob 102 to disconnect,
So as to obtain currently the first controlling brancher 100 be off, and the first air compressor is controlled to start the normally closed of controller 202
Contact 11-12 disconnects, the second air compressor of control starts the normally opened contact 21-22 closures of controller 203, control air compression
The normally opened contact 11-12 closures of machine start and stop time-delay relay 204, so as to obtain currently the second controlling brancher 200 be off,
And current first magnetic valve 300, the second magnetic valve 400 and the 3rd magnetic valve 500 are in unactivated state.
In the present invention, with the draining of draining valve be associated the working condition of air compressor in advance by the present invention.
A feedback signal can be sent to train control system when the normal air feed operation of air compressor, and train control system is detected
After the feedback signal, control command is started based on feedback signal generation air compressor machine and is sent to Auto-drainage valve controling circuit, with
Inform that Auto-drainage valve controling circuit air compressor carries out air feed operation.Now, air compressor keeps operating condition,
First air compressor starts controller 202, the second air compressor and starts controller 203 etc. and must electrically activate, i.e., now the
The normally-closed contact 11-12 that one air compressor starts controller 202 disconnects, the second air compressor starts the normal of controller 203
Open the normally opened contact 11-12 closures of contact 21-22 closures and air compressor start and stop time-delay relay 204.Now second
Controlling brancher 200 is still in off-state.
Simultaneously as the drain knob 102 in the first controlling brancher 100 is not operated, the normally opened contact of drain knob 102
1-2 is remained open, and the first controlling brancher 100 is also at off-state.
It should be noted that in the present invention during train normal operation, when air compressor is not actuated, the first air
The normally-closed contact 11-12 closures of compressor start controller 202, the second air compressor start the normally opened contact of controller 203
21-22 disconnects and the normally opened contact 11-12 of air compressor start and stop time-delay relay 204 disconnects, now the second controlling brancher
200 are off.The normally opened contact 1-2 of the drain knob 102 in the first controlling brancher 100 is constantly in off-state,
First controlling brancher 100 is off.The first controlling brancher 100 and the second controlling brancher 200 i.e. now is in breaking
Open state, the first magnetic valve 300, the second magnetic valve 400 and the 3rd magnetic valve 500 are also in unactivated state.
Step 102, after receiving air compressor machine stopping control command, controls the normally opened contact 1-2 of drain knob 102 to disconnect,
So as to obtain currently the first controlling brancher 100 be off, and the first air compressor is controlled to start the normally closed of controller 202
The normally opened contact 21-22 that contact 11-12 closures, the second air compressor of control start controller 203 disconnects, control air compression
The normally opened contact 11-12 of machine start and stop time-delay relay 204 disconnects after the time delay set time.
Wherein, the set time can be 15s, i.e. air compressor start and stop time-delay relay 204 normally opened contact 11-12 exist
Disconnected after time delay 15s.
In the present invention, when train control system detects air compressor stops air feed operation, also can be to Auto-drainage
Valve controling circuit sends an air compressor machine and stops control command, to inform that Auto-drainage valve controling circuit air compressor has completed to supply
Wind operation is, it is necessary to open draining.
After Auto-drainage valve controling circuit receives air compressor machine stops control command, the first air compressor of control starts
The normally-closed contact 11-12 of controller 202 is closed, the normally opened contact 21-22 of the second air compressor startup controller 203 disconnects,
And the normally opened contact 11-12 of air compressor start and stop time-delay relay 204 disconnects.Yet with air compressor start and stop time delay
The characteristic just disconnected after the time delay set time that relay 204 has in itself, air compressor start and stop time-delay relay 204 it is normal
It is not to disconnect at once to open contact 11-12, but is just disconnected by after time delay set time 15s.
Within the 15s times, the first air compressor starts normally-closed contact 11-12 closures, second air of controller 202
The normally opened contact 21-22 of compressor start controller 203 disconnects and the normally opened of air compressor start and stop time-delay relay 204 touches
Point 11-12 is closed, and is not disconnected, and the second controlling brancher 200 now is in the conduction state.And now the second controlling brancher 200
In second control power supply 201 provide electric current sequentially pass through the first air compressor start controller 202 normally-closed contact 11-
12nd, 204 and second diode of air compressor start and stop time-delay relay 205 flows into draining valve activation train-line so that draining valve
Activation train-line is powered, have activated the first magnetic valve 300, the second magnetic valve 400 being connected respectively with draining valve activation train-line
Draining is performed with the 3rd magnetic valve 500.
After draining continues 15s, the normally opened contact 11-12 of air compressor start and stop time-delay relay 204 disconnects, with this
The first air compressor starts the normally-closed contact 11-12 closures of controller 202, the second air compressor and starts controller simultaneously
203 normally opened contact 21-22 disconnects, and the second controlling brancher 200 returns to off-state, the first magnetic valve 300, the second magnetic valve
400 and the 3rd magnetic valve 500 stop draining.
During the actual operation of train, the operation mode of train includes half train operation pattern, single vehicles operation mode
Or multiple row car weight connection operation mode.Wherein in multiple row car weight connection operation mode, draining valve activation train-line passes through multiple unit socket
It is attached.Above-mentioned Auto-drainage valve controling circuit disclosed by the invention and control method are applied to the various operation moulds of train
Formula, and control circuit is simple, reliability is high.
In actual applications, many air compressions may be included when train uses single vehicles operation mode, in system
Machine, such as T1, T2.During train normal operation, starting an air compressor T1 can meet train wind demand, and
For balance wears away, there is single even-numbered days control model, i.e. odd number day and start T1 cars in the startup management of air compressor, even number day starts
T2 cars.But train is in first time starts daily, it will usually while starting two air compressors, the wind time is beaten to shorten.
Now above-mentioned technical proposal of the invention can also be：
When two air compressors are not actuated, the first air compressor starts the normally-closed contact 11-12 of controller 202
The normally opened contact 21-22 that closure, the second air compressor start controller 203 disconnects and air compressor start and stop time delay relay
The normally opened contact 11-12 of device 204 disconnects, and the second controlling brancher 200 is off, the first magnetic valve 300, the second magnetic valve
400 and the 3rd magnetic valve 500 be in unactivated state.
