Embodiment
This routine sensor construction in cylindricality cavity 10, is equipped with Hall integrated circuit 11, connecting rod 12, permanent magnet 13, spring 14 as shown in Figure 1.Connecting rod 12 can move along axis in cylindricality cavity 10, thereby changes the distance of permanent magnet 13 and Hall integrated circuit 11, and spring 14 is compressed or stretches.Figure 1 shows that spring 14 is in the synoptic diagram of compressive state, permanent magnet 13 and Hall integrated circuit 11 distances are farthest at this moment; Fig. 2 is the synoptic diagram that spring 14 is in extended configuration (state of nature), and this moment, permanent magnet 13 was nearest with Hall integrated circuit 11.
Fig. 3 is sensor 1 and electric pole 2, and the annexation synoptic diagram of drag-line 3.The set collar 16 of sensor 1 is fixed on the electric pole 2 by anchor ear 21, and the connecting rod 12 of sensor 1 ties up to by steel cable 4 on the wire clamp 31 of drag-line 3, and under the effect of drag-line 3 tension force, the connecting rod 12 of sensor 1 is drawn out, and spring 14 is in compressive state, as shown in Figure 1.When drag-line 3 relaxes, connecting rod 12 is under spring 14 effects, move bottom to cylindricality cavity 10, Hall integrated circuit 11 changes with the distance of permanent magnet 13, if drag-line 3 is cut off, spring 14 will be got back to state of nature, and Hall integrated circuit 11 is nearest with permanent magnet 13, as shown in Figure 2.Along with the variation of Hall integrated circuit 11 with permanent magnet 13 distances, the output signal of Hall integrated circuit 11 also can change, and whether the variation of this signal just can detect drag-line and relax or fracture by cable 15 input control circuits.
This routine control circuit block diagram is referring to Fig. 4.Its Single Chip Microcomputer (SCM) system is by squegger 41, and microprocessor 40 constitutes, and squegger 41 is to microprocessor 40 output periodicity activation signals.These activation signals of microprocessor 40 response allow the starting of oscillation of crystal oscillator (not shown).It is 5～30us pulse drive signal that microprocessor 40 produces width, and by pulse power supply device 42, the pulse voltage of the about 2V of output provides the pulsed operation electric current to comparer 43 and Hall integrated circuit 11.In order to protect Hall integrated circuit, can be at the output terminal parallel voltage-stabilizing diode of Hall integrated circuit.In this example, comparer 43 is two voltage comparators, and the reference voltage of two comparer is separately positioned on 1.3V and 0.6V.If the permanent magnet 13 in the sensor 1 is because of the close Hall integrated circuit 11 of relaxing of drag-line 3 and reach detection threshold, or because of outside people is short circuit, opens circuit, the output level state of two comparers all can change.Microprocessor 40 judges according to the level state of two comparers whether decision reports to the police.The time of waiting for is not to comparer 43 and Hall integrated circuit 11 power supplies, with the abundant saving energy content of battery.
