Problems solved by technology

[0003] At present, the traditional industry practice is to integrate the hard clock chip, debugging serial port, USB serial port, etc. on the meter communication module. The hard clock chip virtually increases the cost and device complexity of the meter communication module, resulting in device redundancy

Abstract

The embodiment of the invention provides a clock synchronization method and device and an electric meter communication module. The clock synchronization method comprises the following steps: acquiringbase meter time and current time of the electric meter communication module, judging whether the current time of the electric meter communication module meets a time synchronization condition or not,and when the current time of the electric meter communication module meets the time synchronization condition, synchronizing the current time of the electric meter communication module by taking thebase meter time as a reference. Therefore, the time accuracy is ensured, the cost increase and the device complexity of the ammeter communication module due to the use of a hard clock chip are avoided, and the device redundancy is avoided.

Description

technical field [0001] The invention relates to the field of household electric meter clocks, in particular to a clock synchronization method, device and electric meter communication module. Background technique [0002] The meter communication module is installed on the user's household electricity meter, and is used to read the user's electricity related data and report it to the main station. One meter communication module corresponds to one household electricity meter, and the concentrator can read hundreds of household electricity meters at the same time. Therefore, when installed When using the meter communication module, a separate concentrator terminal is not required. [0003] At present, the traditional industry practice is to integrate the hard clock chip, debugging serial port, USB serial port, etc. on the meter communication module. The hard clock chip virtually increases the cost and device complexity of the meter communication module, resulting in device redu...
