Abstract

Embodiments of the present invention propose a clock synchronization method, device, and ammeter communication module. The clock synchronization method includes: acquiring the base meter time and the current time of the ammeter communication module, and judging whether the current time of the ammeter communication module satisfies the time synchronization condition. When the current time of the module meets the time synchronization conditions, the current time of the meter communication module is synchronized with the base meter time; thus ensuring the accuracy of the time, and avoiding the use of hard clock chips to increase the cost and device complexity of the meter communication module , to avoid device redundancy.

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...
