Abstract

The invention provides a Bluetooth communication method of electric power metering on-site test data. The Bluetooth communication method is implemented by a mobile operation terminal serving as a master station and on-site test devices serving as slave stations. All on-site test devices are provided with address codes. A master-slave half-duplex communication method is adopted for communication between the master station and the slave stations for data exchange. Establishment and termination of communication links between the master station and the slave stations are controlled by information frames sent by the master station. An information frame is composed of seven fields: a frame start character, a slave address field, a control code, a data field length, a data field, a frame information longitudinal check code and a frame terminator. Each field of the information frame is composed of bytes. Data transmission and communication between the master station and the slave stations is performed according to set statutes. According to the method, data acquisition is simple, and communication statutes are concisely and clearly defined. The Bluetooth communication method can be implemented on site conveniently, can be used to automatically, quickly and accurately acquire electric metering on-site test data. The method is of strong applicability and good generality, and is convenient for promotion.

Description

technical field [0001] The invention relates to a bluetooth communication method, in particular to a bluetooth communication method for power metering on-site detection data. Background technique [0002] For a long time, the acquisition of test data at the measurement site (electric energy meter) of the electric power department is usually carried out by the tester carrying the calibrator at the measurement site for calibration and testing, and then the test results are manually recorded on the notebook, and then the calibration results are returned 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 of 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 been gradual...
