Embodiment
Below in conjunction with the control of the locomotive logic control element in the diesel locomotive, content of the present invention is done detailed description to electromagnetic chain control coil and fuel pump control coil.
Simultaneously, two the corresponding relay coil 1ZJA in contact, 2ZJA link to each other with switching controls end OUT1, the OUT2 end that described numeral is gone into out plug-in unit respectively, constitute a switching controls branch road separately, in order to guarantee that two normally opened contacts of 1ZJC, 2ZJC can be in closure state in handoff procedure, respectively two normally opened contact 1ZJB, 2ZJB are connect ground end, thereby two relay coils of 1ZJA, 2ZJA have been communicated with into self-holding circuit with the ground end with+110V power end, and have formed the self-sustaining of relay 1ZJ and 2ZJ.Thereby,, realize uninterrupted handoff functionality with self-holding circuit and standby work loop by described switching circuit.
In relay coil 1ZJA, the 2ZJA loop also respectively series connection advanced two normally closed contact 3ZJB and 3ZJC, described normally closed contact 3ZJB and 3ZJC are by controlling with the described numeral relay coil 3ZJA that the control end of plug-in unit links to each other that comes in and goes out.
During operate as normal (during non-switching state), cut-off control end OUT3 and pilot relay coil 3ZJA that numeral is gone into out on the plug-in unit constitute and cut-off control loop, must not be electric by the described control end OUT3 pilot relay coil 3ZJA that cut-offs, two normally closed contact 3ZJB, 3ZJC are remained closed.Simultaneously, numeral go into out switching controls end OUT1, OUT2 on the plug-in unit drive respectively transfer relay coil 1ZJA, 2ZJA get electric, thereby four normally opened contact 1ZJB, 1ZJC, 2ZJB, 2ZJC are all closed.Like this, relay coil 1ZJA just is in the closed electric loop: the normally opened contact 1ZJB → ground end of the normally closed contact 3ZJB → closure of+110V power end → transfer relay coil 1ZJA → closure.In like manner relay coil 2ZJA also is in the closed electric loop: the normally opened contact 2ZJB → ground end of the normally closed contact 3ZJC → closure of+110V power end → transfer relay coil 2ZJA → closure.
When numeral is gone into out plug-in unit moment dead electricity, when promptly entering in the handoff procedure, described numeral is gone into out the control end OUT-RBC commonly used of plug-in unit, OUT-DLS continues because of dead electricity can't continue to drive described fuel pump control coil RBC and electromagnetism interlocked control coil DLS crucial coil, but because above-mentioned transfer relay coil 1ZJA, 2ZJA has all constituted closed electric loop, and these two closed-loop paths can't cause the loop to disconnect because numeral goes into out plug-in unit moment dead electricity, like this, fuel pump control coil RBC and two crucial coils of electromagnetism interlocked control coil DLS still can be kept by following two closed-loop paths respectively: the normally opened contact 1ZJC → ground end of+110V power end → electromagnetism interlocked control coil DLS → closure; Normally opened contact 2ZJC → ground the end of+110V power end → fuel pump control coil RBC → closure is not shut down thereby can keep in the locomotive diesel engine and other service part continuous runnings in handoff procedure, finishes handoff procedure stably.
After numeral is gone into out plug-in unit recovery normal operating conditions, get by the described described relay 3ZJ that cut-offs of control end OUT3 output control signal control that cut-offs, corresponding normally closed contact 3ZJB, 3ZJC are disconnected, and then transfer relay coil 1ZJA, 2ZJA dead electricity are quit work, thereby the controlled object unit is quit work, even electromagnetic chain control coil and fuel pump control coil quit work.
In addition, described switching circuit is gone into out grafting respectively by numeral two different control ends realization controls can realize the asynchronous control to different coils in the controlled object unit, satisfy the sequential requirements of different control occasions.
Loop described in the application refers to that two ends are connected between the power positive cathode, or between the high-low level, and can form current paths.Therefore, described embodiment 1,2 also can derive two kinds of mutation respectively, be about among the embodiment 1,2+110V power end and ground end put upside down mutually, as long as can constitute described loop, promptly can form current paths and get final product, the circuit structure and the course of work are identical, repeat no more here.
