Abstract

The invention provides a bluetooth communication method for on-site detection data of electric power metering, which is implemented by a mobile operation terminal as a master station and an on-site detection device as a slave station; the on-site detection devices are all provided with address codes; the master station and the slave station use a master- The half-duplex communication mode of the slave structure performs data exchange through the information frame; the establishment and release of the communication link between the master station and the slave station are controlled by the information frame sent by the master station; the information frame is composed of the frame start character, the address field of the slave station, Control code, data field length, data field, frame information longitudinal check code and frame end character are composed of 7 fields; each field of the information frame is composed of bytes; data transmission and communication between the master station and the slave station are carried out according to the set protocol . The invention has concise and clear definitions of data collection and communication protocols, is convenient for on-site implementation, can automatically, quickly and accurately obtain on-site detection data of power metering, has strong applicability, good versatility, and is easy to popularize.

Description

technical field

[0001] The invention relates to a bluetooth communication method, in particular to a bluetooth communication method for on-site detection data of electric power metering. Background technique

[0002] For a long time, the acquisition of test data at the metering site (electric energy meter) in the power department is usually carried out by the tester with a calibrator to carry out calibration and testing at the metering site, and then manually record the test results in a notebook, and then return the calibration results to the unit. This traditional method is time-consuming and labor-intensive, and it is easy to cause errors and loss of verification data entry.

[0003] In recent years, with the development of informatization in electric power enterprises, in order to improve the efficiency of on-site inspection of power metering and the accuracy of on-site inspection data, wireless communication technologies such as Bluetooth have gradually been applied. T...
