Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0034] The Bluetooth module in the new IoT energy meter is connected to the MCU through the UART port, which can realize full-duplex data transmission between the Bluetooth module and the MCU. The meter calibration process of traditional electric meters is as follows: figure 1 The part of the solid line in , that is, the meter calibration device (the platform in the figure) performs pulse accumulation through electric pulses or light pulses; for the new IoT electric energy meter, appropriate improvements have been made on the basis of the traditional process, namely figure 1 The dotted line part, the specific process is as follows:

[0035] Initialize first: establish a connection between the ...

Abstract

The invention discloses a meter calibration method based on bluetooth communication frames. Generate corresponding pulse data; send the pulse data to the accumulative controller side for pulse accumulation to realize error calibration. At the same time, the corresponding system and device are disclosed. The invention transmits the custom frame corresponding to the accumulated pulse, and converts the custom frame into pulse data according to the verification result, and realizes the error calibration applicable to the new IoT electric energy meter through the accumulation of the pulse data.

Description

technical field [0001] The invention relates to a meter calibration method, system and meter calibration device based on bluetooth communication frames, belonging to the field of electric energy meter calibration. Background technique [0002] Based on the multi-core scheme of the Internet of Things energy meter, the traditional communication method between modules is realized through the weak current terminal of the electric pulse signal. When the meter is calibrated, the pulse is accumulated through the communication harness, and finally the accumulated pulse data is connected to the standard source. The difference of the standard pulse data is used for error calibration. At present, the latest IoT watt-hour meters use Bluetooth communication between modules, and the traditional meter calibration method cannot be applied to the new IoT watt-hour meters. Contents of the invention [0003] The invention provides a meter calibration method, system and meter calibration dev...
