Multi-channel anti-collision method and system for electric energy meter verification

Abstract

The invention discloses a multi-channel anti-collision method and system for electric energy meter verification, and belongs to the technical field of wireless communication. The method comprises the following steps: acquiring a communication address of a to-be-calibrated electric energy meter, determining pulse calibration parameter information and sending the pulse calibration parameter information to the to-be-calibrated electric energy meter; obtaining pulse verification parameter information, returning a response frame through pulse verification parameters, and switching the Bluetooth module to a private wireless working mode; after the management module receives a command of the detection platform body, switching the Bluetooth module to a private wireless working mode through a communication address and a channel in pulse detection parameters; switching transmission pulse signals according to multiple channels in the verification parameters, obtaining return confirmation information, and stopping switching transmission after confirmation; replying an acknowledgement frame according to the received multi-channel signal, determining a pulse signal, and restoring a pulse to the table body after processing. Under the condition that multiple electric energy meters are calibrated, the calibration precision is met, communication during calibration is supported at the same time, and the detection efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a multi-channel anti-collision method and system for electric energy meter verification. Background technique [0002] At present, when the smart energy meter is inspected on the platform or on the automatic line, the commonly used communication method is RS485, and the pulse output mode is the auxiliary terminal. In the design of the next generation of multi-core modular smart energy meter, the auxiliary terminal is canceled. Use Bluetooth instead of RS485 communication, and LED light pulses instead of auxiliary terminal pulses. Under this background, if all the pulse receiving devices of the table body or automatic line are replaced with optical signal receiving heads, there will be problems of high reconstruction cost, long cycle, and rare optical signal holes. , in order to reduce the cost and difficulty of equipment transformation, as ...
