Communication module with outage detection and alarm functions and outage detection alarm method

Abstract

A communication module with outage detection and alarm functions comprises: an MCU; a weak current interface detection circuit connected with the MCU, wherein an input end of the weak current interface detection circuit is connected with a weak current interface of an electric energy meter to collect a voltage value of a power end of the weak current interface of the electric energy meter; a strong current interface detection circuit connected with the MCU, wherein an input end of the strong current interface detection circuit is connected with a strong current interface of the electric energymeter; a communication circuit connected with the MCU, wherein the communication circuit is connected with an antenna; a DC-DC circuit connected with the MCU, wherein an input end of the DC-DC circuit is connected with a power end of the weak current interface power end of the electric energy meter and is configured to supply power to the MCU, the communication circuit and a Farad capacitive circuit; and the Farad capacitive circuit connected with the DC-DC circuit, the MCU and the communication circuit. The communication module with outage detection and alarm functions and the outage detection alarm method can achieve outage detection and alarm functions for the electric energy meter and provide fault information for power enterprises.

Description

technical field [0001] The invention belongs to the technical field of wireless meter reading, and in particular relates to a wireless communication module with power failure detection and power failure alarm functions and a power failure detection and alarm method. Background technique [0002] At present, in the smart energy meter specifications defined by the State Grid and China Southern Power Grid, there is no provision for the transmission of power failure alarm information between the energy meter and the communication module. Therefore, the communication module that complies with the electric energy meter specifications of the State Grid and the Southern Power Grid cannot know whether the electric energy meter is out of power, and the communication module does not support reporting the power outage information to the main station. In this way, the power company cannot know the user's power outage failure in time, nor can it troubleshoot and repair the failure in time...
