In addition, the first distance sensor and the second distance sensor are both infrared distance measuring sensors.
The working mode of the antimagnetic shield 6 of the invention is as follows:
after the internet of things platform receives a request of a field worker or a user and sends a locking instruction for installing the antimagnetic cover 6 to the processor, the processor controls the second micro electromagnet 25 to be electrified so that the push pin 28 retracts into the transverse groove 32; the elastic push strip 11 of the magnetic shield 6 or the main buckle 10 will trigger the first distance sensor to generate a signal in the downward moving process, and when the distance reaches a preset distance, the processor controls the second micro-electromagnet 25 to be powered off, so that the push pin 28 pushes the elastic push strip 11, and the elastic clip 13 of the main buckle 10 moves to the lower part of the locking groove 20. During the movement, the upper end surface of the spring clip 13 is in contact with the inner wall of the lock groove 20, so that the spring clip 13 is in a contracted state.
When the main buckle 10 moves to the lower part of the locking groove 20, the second distance sensor detects a corresponding signal, the processor receives the signal and can confirm the position of the main buckle 10, and at the moment, the processor controls the first micro-electromagnet 23 to be electrified to suck the push block 22 to the upper part of the locking hole 21, so that the elastic clamp 13 can enter the locking hole 21 conveniently; and the locking is completed after the power is cut off after the preset delay time. At this time, since the push block 22 has a proper frictional resistance, the locking effect is not affected.
When the antimagnetic shield 6 needs to be opened, a user needs to send a request for opening the antimagnetic shield 6 to the platform, and the platform receives the request and then sends an instruction for opening the antimagnetic shield 6 to the processor. At this time, the user needs to use the contact pin to press the elastic clip 13 downwards by the push block 22 along the contact pin hole 24 to make the elastic clip exit from the lock hole 21, at this time, the processor simultaneously controls the second micro-electromagnet 25 to be electrified to pull the push rod back into the transverse groove 32, and at this time, the main buckle 10 is far away from the lock hole 21 under the restoring force of the elastic push bar 11, so as to realize unlocking.
After the antimagnetic shield 6 is installed, if the main buckle 10 is damaged by external force, the antimagnetic shield 6 is opened, the main buckle 10 cannot be repaired, and the second electromagnet is controlled by the management platform, namely, the processor can work only when being authorized by the platform, and the push rod is used for pushing the elastic push strip 11. Therefore, even if the shape of the antimagnetic shield 6 is recovered by violent disassembly, the antimagnetic shield cannot be installed again, so that an inspector can directly observe whether the water meter is damaged or not. This is advantageous in order to reduce attempts by water thieves to steal water by destroying the antimagnetic shield 6.
