It states.
Wherein, as shown in Figure 1, trailer system acquires four kinds of direction signals altogether, comprising: to after (No. 4 lines), rigid line before rigid line
It is backward (No. 2 lines) to (Line 1) and network before to (No. 3 lines), network；Meanwhile speed sensor signal is acquired, to judge to run
Speed.
Fig. 2 is a kind of flow chart of vehicle traction system direction selective method, this method it is total include: acquisition hard signal
And network signal, compare the direction of hard signal and network wire size；Hard signal and network signal one of them or it is more
When a traffic direction is inconsistent, speed signal is acquired；If the current speed of service is zero, traction convertor is blocked, if network is believed
Number direction and controller direction are inconsistent, cut off network signal；Judge whether rigid line direction is consistent with controller direction, if direction
Unanimously, continuous service is to terminal.
Wherein, when hard signal is consistent with network signal direction, the traffic direction of train is maintained, continues to run or opens
Motor-car.
Wherein, driver pushes controller directional lever forward or backward, and traction convertor acquires hard signal and network letter
Number, hard signal includes before rigid line to backward with rigid line, and network signal includes before network to backward with network, comparison two-way totally four
Whether a direction signal, confirmation direction signal are consistent.
Wherein, in one embodiment, speed sensor signal is acquired by traction convertor in real time, according to velocity pick-up
Device signal judges car speed.
Wherein, in one embodiment, if the current speed of service is not zero, indicate that vehicle is currently running, operation side
To consistent with controller direction.Traction convertor is not blocked at this time, vehicle is maintained to continue to run, and pops up failure letter on a display screen
Breath prompts driver.
Wherein, in one embodiment, if the current speed of service is zero, indicate that vehicle has stopped, block is led at this time
Draw current transformer, vehicle is unable to run, while popping up fault message on a display screen.
Wherein, in one embodiment, the traffic direction and controller traffic direction on display screen are compared, if direction one
It causes, then proves that the network signal of display screen display is correct, then confirm releasing traction block, run according to the direction of network signal
Vehicle.
Wherein, in one embodiment, if traffic direction and controller direction are inconsistent on display screen, then it is assumed that display screen
The network signal of upper display is incorrect, is confirmed as network failure, and operation is gone to contingency mode, network signal is cut off at this time, tastes
Try motor-car.
It is wherein, in one embodiment, when confirmation rigid line direction and controller direction are inconsistent or still faulty when quoting,
Traction convertor is then blocked, vehicle is out of service, waits for rescue.
Specifically, in one embodiment, by controller forward for be described in detail.
Wherein, this method includes comparison direction signal.Specifically, driver pushes forward controller directional lever, and traction becomes
Device acquisition hard signal and network signal are flowed, is obtained about rigid line forward signal, rigid line backward signal, network forward signal and net
Network backward signal, and rigid line direction signal and network direction signal are compared, 16 kinds of composite types can be generated, see the table below, wherein 0 generation
Table is invalid, and 1 represents effectively.
| Composite type | Before rigid line to | Rigid line is backward | Before network to | Network is backward | Trailer system judging result | Remarks |
| 1 | 0 | 0 | 0 | 0 | Block traction | Normally |
| 2 | 1 | 0 | 1 | 0 | Forward direction operation | Normally |
| 3 | 0 | 1 | 0 | 1 | Backward operation | Normally |
| 4 | 0 | 0 | 1 | 1 | Direction signal is inconsistent | Failure |
| 5 | 1 | 1 | 0 | 0 | Direction signal is inconsistent | Failure |
| 6 | 1 | 1 | 1 | 1 | Direction signal is inconsistent | Failure |
| 7 | 1 | 0 | 0 | 0 | Direction signal is inconsistent | Failure |
| 8 | 1 | 0 | 1 | 1 | Direction signal is inconsistent | Failure |
| 9 | 0 | 1 | 0 | 0 | Direction signal is inconsistent | Failure |
| 10 | 0 | 1 | 1 | 1 | Direction signal is inconsistent | Failure |
| 11 | 0 | 1 | 1 | 0 | Direction signal is inconsistent | Failure |
| 12 | 0 | 0 | 1 | 0 | Direction signal is inconsistent | Failure |
| 13 | 1 | 1 | 1 | 0 | Direction signal is inconsistent | Failure |
| 14 | 1 | 0 | 0 | 1 | Direction signal is inconsistent | Failure |
| 15 | 0 | 0 | 0 | 1 | Direction signal is inconsistent | Failure |
| 16 | 1 | 1 | 0 | 1 | Direction signal is inconsistent | Failure |
Only when hard signal and network signal select one respectively, while hard signal is consistent with network signal, it is believed that
Direction signal is normal.Wherein, that is, the 1-3 of the composite type of table as above, wherein rigid line and network signal are all zero, are in
The state or rigid line and network for blocking traction be all before to being perhaps all backward to be run in preceding to operation or backward
State, train operation are normal.In addition to this remaining 13 kinds of situation, it is inconsistent to belong to direction signal, is in malfunction.
When direction signal is normal, vehicle can be continued to run or started；If direction signal is inconsistent, further to judge
The speed of service of train.Speed sensor signal is acquired in real time by traction convertor, is judged according to speed sensor signal
Car speed.If car speed is not zero, indicate that vehicle is currently running, traffic direction is consistent with controller direction, does not seal at this time
Traction convertor is locked, vehicle is maintained to continue to run, pops up fault message on a display screen, prompts driver；If car speed is zero,
It indicates that vehicle stops, blocking traction convertor at this time, vehicle is unable to run, and pops up fault message on a display screen.
Then, the traffic direction and controller traffic direction on display screen, if the two direction is consistent, network signal are compared
Correctly, confirmation releases traction block, runs vehicle according to the direction of network signal；If traffic direction and controller side on display screen
To inconsistent, then it is assumed that network failure goes to contingency mode, cuts off network signal at this time, attempts motor-car.
Finally, driver pushes controller directional lever, only hard signal at this time judges whether are traffic direction and controller
Direction is consistent, if direction is consistent, continues to run until terminal, if direction it is inconsistent or it is still faulty quote, block traction, wait
Rescue.
