Application of optical sensor in automatic meter reading system！

In order to settle the user's electricity bills in time, the power department usually sends a special meter reading personnel to the relevant users to view and copy the electric energy meter set on the spot periodically and manually read, record, calculate and charge. . This not only wastes a lot of manpower, but also causes unnecessary errors due to manual reading, and sometimes brings unnecessary troubles and losses to the users. Some criminals even falsely copy the metering personnel into the room and commit crimes and affect the society. In addition, it is not easy for the power sector to carry out modern management. Therefore, both the power sector and users are eager to change the backwardness current state. With the development of microelectronics, sensor technology, computer technology and modern communication technology, optical sensors can now be used to develop automatic meter reading systems.

The aluminum plate of the electric energy meter is rotated by the torque generated by the eddy current and the magnetic field. The use of photoelectric sensors converts the number of revolutions of an aluminum disk into pulses. The use of photoelectric coupler can effectively prevent interference signals from entering the microcomputer. Combined with other transmission methods can form an automatic meter reading system.

At present, the automatic meter reading system has not yet been used on a large scale. This current technology has a lot to do with the current technology is not very mature, There's a lot of room for improvement, With the development of technology, automatic meter reading will be realized throughout the country in the next few years.
