Detailed description of the invention

In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, well lid displacement monitoring device based on GSM and magnetic inductor, comprise magnet 1, described magnet 1 is arranged on well lid downside, magnet 1 connects gauge tap A2, switch A2 is connected to single-chip microcomputer 6 by time-delay relay 4, switch A, time-delay relay 4 is powered by battery 3, single-chip microcomputer 6 connects controls acoustic-optic alarm 8, reducing transformer 9 is installed on acoustic-optic alarm 8, described single-chip microcomputer 6 is connected and is controlled SMS alarming device 7 by data wire 5, described acoustic-optic alarm 8 comprises audible-visual annunciator, limitation travel switch SC1, A.C. contactor 1QF1, D.C. contactor KM63, dc source, the red line of described audible-visual annunciator meets first of D.C. contactor KM63 and often opens auxiliary contact 23 ends, the first normally opened contact 24 termination D.C. contactor KM63 normally-closed contact 22 ends of D.C. contactor KM63,24 ends of the normally opened contact of the normally-closed contact 21 termination A.C. contactor 1QF1 of D.C. contactor KM63, the yellow line of 23 termination audible-visual annunciators of the normally opened contact of A.C. contactor 1QF1, 22 ends of the normally-closed contact of the normally-closed contact 22 termination A.C. contactor 1QF1 of D.C. contactor KM63, the green line of 21 termination audible-visual annunciators of the normally-closed contact of A.C. contactor 1QF1, the second normally opened contact 14 ends of 22 termination D.C. contactor KM63 of the normally-closed contact of A.C. contactor 1QF1,14 ends of the normally opened contact of the second normally opened contact 13 termination travel switch SC1 of D.C. contactor KM63, the orange line of 13 termination audible-visual annunciators of the normally opened contact of travel switch SC1: the normally-closed contact 21 and 22 of travel switch SC1 is serially connected in the control loop of D.C. contactor line bag simultaneously, described power acquisition 24V dc source, the black line of 22 termination first sound light crossing-signals of A.C. contactor 1QF1 normally-closed contact, purple 2 lines of audible-visual annunciator meet the 24V+ of dc source, and purple 1 line meets the 24VGND of dc source.

Described battery 3 is 5V battery.

Operation principle of the present utility model is: power-off at ordinary times, when being triggered to well lid, magnetic inductor has displacement, will Time delay relay, shake is fallen in time-delay relay automatic fitration, if well lid displacement a period of time is such as after 10 seconds, just start to system power supply, audible-visual annunciator starts to report to the police, and starts to send alarming short message.

There is more practical value compared with anti-stealing manhole cover on market. Do not suffer a loss and protect personal safety for the protection of national wealth, preventing pedestrian and fall the accident of well.
