Research on wireless calibration technology of watt-hour meter based on Bluetooth
At present, the error inspection of traditional watt-hour meter usually uses manual wiring. It is inefficient in this way, any improper operation will cause damage to the device and lead to potential security risks. In this paper, Bluetooth technology is used for the batch meter inspection processing. As a reliable wireless technology, the new method can greatly improve the operation efficiency and reduce any potential risks. This paper adopts a special Bluetooth mode instead of normal mode, transmitting the pulsing signal directly from the underlying basic registers instead of forwarding the signal from the application protocol layer. In this way, it can greatly enhance the stability of the signal forward. The tests indicate that the stability can be managed within 1μs, it can meet the requirements of all watt-hour meter calibration accuracy level. During the detection, there is no need to connect the photoelectric head on the meter body with the optical pulse interface and electric pulse interface of the meter to be tested, which reduces manual participation and improves the error inspection efficiency of batch electricity meters. The wireless photoelectric pulse calibration system based on Bluetooth technology is suitable for the detection of waiting electricity meter with wireless transmission module.
