Accompanying drawing explanation
Fig. 1 is the planar view of a kind of coal conveyer belt of power plant startup of the utility model and warning.
Detailed description of the invention
Consult shown in Fig. 1, a kind of coal conveyer belt of power plant starts and warning, includes warning and start up system, and described warning system and start up system organically combine, make original warning and start up system become a Unified Global, described warning includes alarm button, alarm bell always exports, add calculator, comparator I (1), comparator II (2), comparator III (3), timer I (1), timer II (2), timer III (3), timer IV (4) and timer V (5), described timer I (1), timer II (2), timer III (3), timer IV (4) and timer V (5) is respectively to there being alarm bell timing I (1), alarm bell timing II (2), alarm bell timing III (3), alarm bell timing IV (4) and alarm bell timing V (5), described in add calculator and be provided with 0, 1, 2 three numbers, described in add calculator export to there being three comparator I (1), comparator II (2) and comparator III (3), described comparator I (1), comparator II (2) and comparator III (3) respectively with timer I (1), timer II (2), timer III (3) is connected, described timer I (1), timer II (2), timer III (3) is to there being alarm bell timing I (1), alarm bell timing II (2) and alarm bell timing III (3), by single job alarm button, alarm bell continuous ringing 15 seconds, after alarm bell terminates for the first time, allow second time by operation alarm button, alarm bell continuous ringing 10 seconds, after second time alarm bell terminates, allow third time by operation alarm button, alarm bell continuous ringing 5 seconds.And after stopping 30 seconds by alarm bell for the third time, PLC logic side can allow to start belt operation, and described start up system includes start button, starts belt, timer VI (6) and timer VII (7).
The control of described timer VI (6) starts bell and starts belt.
As preferably, in described warning and start up system, be provided with relay.
According to Fig. 1, known:
Native system have employed a counter, it is set to 0,1,2 three numbers, carry out adding count operation, three comparators corresponding to its output, select equal condition, arrange 0,1,2 three numbers respectively, it is 0 that counter initially exports count value, comparator I (1) conducting corresponding with it.
Its workflow is:
1) when pressing alarm button, sending " alarm bell always exports " signal, making " electric bell output " actuating of relay, realize first time alarm bell warning; Then make timer I (1) conducting, time delay 15s sends " alarm bell timing I (1) " signal, make counter conducting, exporting count value is 1, makes comparator II (2) conducting corresponding with it; Simultaneously instantaneous trip " alarm bell always exports " signal, first time bell ring report to the police and terminate, and cut off alarm bell timing I (1) signal that timer I (1) exports, for next button alarm is prepared.
2) when again pressing alarm button, sending " alarm bell always exports " signal, making " electric bell output " actuating of relay, realize second time alarm bell and report to the police; Then make timer II (2) conducting, time delay 10s sends " alarm bell timing II (2) " signal, make counter conducting, exporting count value is 2, makes comparator III (3) conducting corresponding with it; Simultaneously instantaneous trip " alarm bell always exports " signal, second time bell ring is reported to the police and is terminated, and cuts off " alarm bell timing II (2) " signal that timer II (2) exports, for next button alarm is prepared.
3) when third time presses alarm button, send " alarm bell always exports " signal, make " electric bell output " actuating of relay, realize second time alarm bell and report to the police; Then make timer III (3) conducting, time delay 5s sends " alarm bell timing III (3) " signal, make counter conducting, export count completion signal " C3.DN "; Simultaneously instantaneous trip " alarm bell always exports " signal, third time bell ring report to the police and terminate, and cut off " alarm bell timing III (3) " signal that timer III (3) exports, for next button alarm is prepared.
4) through operating above, when counter sends count completion signal " C3.DN ", triggering " alarm bell self-locking " signal, cutting off " alarm bell always exports " signal, locking alarm bell is reported to the police; Then reset counter is made to send " reset count " signal, counter is made to return to initial condition, make timer IV (4) conducting simultaneously, " alarm bell timing IV (4) " signal is sent after time delay 30s, trigger " startup self-locking " signal, sending " alarm bell unblock " signal simultaneously, preparing for ringing the doorbell warning next time.
5) after " startup self-locking " signal sends, just can press " start button ", trigger " start and prepare " signal.Now, as " long-range " and " startup self-locking " blackout or " fault ", " stay cord ", " start and export ", " tearing ", " start and prepare to remove ", " startup cancel button " and " maintenance " arbitrary road signal come, all will cut off " startup preparation " signal.
6) after " startup prepares " signal comes, press " start and confirm " button, trigger " start and prepare to remove " signal, " will start and prepare " signal excision, timer VI (6) conducting simultaneously sends " startup bell " signal, make " electric bell output " actuating of relay, start bell ring, " startup belt " signal is sent after 5s, cut off " startup bell " signal and " start and the prepare to remove " signal that resets, prepare for next time " starts and prepares ", " start and export " actuating of relay simultaneously, coal conveyer belt starts, and " will start and prepare " signal excision; And make timer VII (7) conducting, time delay 2s disconnection " starts and export " relay, prepare for next time " starts preparation ".
7) after " startup self-locking " signal sends, can allow to start.Make timer V (5) conducting, time delay 180s, send " alarm bell timing V (5) " signal, trigger " start and unlock " signal, cut off " start and prepare " signal, namely start as failed in this 180s, then this time start failure, only have next alarm bell by the time can again allow after reporting to the police to start.
In sum, by the improvement to system, can realize having to pass through before coal conveyer belt starts alarm bell and report to the police and can allow to start, thus when guaranteeing that coal conveyer belt starts near it related personnel obtain clear and definite alarm, and withdraw hazardous location safely, guarantee the person and device security.
The beneficial effects of the utility model are: startup and warning due to coal conveyer belt organically combine to be connected, export there being three comparator I (1) with the described calculator that adds, comparator II (2) and comparator III (3), described comparator I (1), comparator II (2) and comparator III (3) respectively with timer I (1), timer II (2), timer III (3) is connected, described timer I (1), timer II (2), timer III (3) is to there being alarm bell timing I (1), alarm bell timing II (2) and alarm bell timing III (3), the necessary condition that the electric bell alarming of three different modes starts as coal conveyer belt, guarantee that near coal conveyer belt, related personnel obtains clear and definite alarm before coal conveyer belt starts, and withdraw hazardous location safely.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
