Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of station end communication power supply exchanges the dead electricity alarm device, and it comprises first relay J 1, second relay J 2, push-button switch AN, indicator light ZS and electric bell DL;
Wherein, the coil two ends of described first relay J 1 are respectively applied for docking station end communication power supply two ends;
Coil one end of described second relay J 2 connects described push-button switch AN one end, the described push-button switch AN other end connects normally opened contact J1-1 one end of described first relay J 1 and the first normally opened contact J2-1, one end of described second relay J 2 respectively, and the normally opened contact J1-1 other end of described first relay J 1 connects the first normally opened contact J2-1 other end of described second relay J 2;
The normally opened contact J1-1 other end of described first relay J 1 connects back contact J1-2 one end of described first relay J 1, the back contact J1-2 other end of described first relay J 1 connects the second normally opened contact J2-2, one end of described second relay J 2, the second normally opened contact J2-2 other end of described second relay J 2 connects described electric bell DL one end, and the described electric bell DL other end connects the coil other end of described second relay J 2;
The coil other end of described second relay J 2 connects described indicator light ZS one end, and the described indicator light ZS other end connects the second normally opened contact J2-2, one end of described second relay J 2;
The normally opened contact J1-1 other end of the coil other end of described second relay J 2 and described first relay J 1 is respectively applied for the UPS accessory power supply two ends of docking station end communication power supply.
Operation principle: behind first relay J, the 1 access station end communication power supply, its normally opened contact J1-1 closure, back contact J1-2 disconnects, and at this moment, the UPS accessory power supply of the end communication power supply of standing powers up for second relay J 2 through normally opened contact J1-1, push-button switch AN; When second relay J 2 powered up, normally opened contact J2-1, normally opened contact J2-2 were closed simultaneously; At this moment, indicator light ZS and electric bell DL remain static;
When the end communication power supply AC dump of station, 1 action of first relay J, normally opened contact J1-1 disconnects, back contact J1-2 closure; At this moment, because the self-sustaining effect of normally opened contact J2-1, second relay J 2 still is in previous status, that is: normally opened contact J2-1 closure, normally opened contact J2-2 closure; Then, the UPS accessory power supply of the end communication power supply of standing powers up for indicator light ZS and electric bell DL, and the bright bell ring of lamp this moment sends warning message;
On-the-spot operator on duty receives the report for police service after the information, can be in time to relevant Communication Personnel's report, so that the Communication Personnel in time goes to processing; Simultaneously, on-the-spot operator on duty can press push-button switch AN, forces 2 outages of second relay J to discharge, and normally opened contact J2-1, normally opened contact J2-2 disconnect simultaneously, cut off electric bell DL loop, and electric bell stops sounding; At this moment, normally opened contact J1-1 is still in closure, and indicator light ZS keeps luminance, that is, this demonstration inform the operator on duty stand the end communication power supply still be in abnormality; After station end communication power supply Alternating Current Power Supply recovers normally, 1 action of first relay J, it is normal that device recovers.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
