Gas meter communicating according to power supply condition and remote communication method thereof

Abstract

The invention relates to the field of gas meters, in particular to a gas meter communicating according to the power supply condition and a remote communication method thereof. The gas meter comprisesa main control module, a metering module, a remote communication module, a main power supply module and a secondary power supply module. When the main power supply module enters a low power state froma normal state, the main power supply module still supplies power to the main control module, the metering module and the remote communication module, and the main control module closes the valve andcontrols the remote communication module to upload meter end information. When the main power supply module enters the failure state from the normal state, the auxiliary power supply module suppliespower to the main control module, the metering module and the remote communication module, and the main control module closes the valve and controls the remote communication module to upload the meterend information. The gas meter has the following beneficial effects: after the main power supply module fails, the gas meter can still close the valve through the control module and controls the remote communication module to upload the meter end information, thus avoiding the loss caused by gas running under the condition and enabling the server end to know the state of the gas meter in time.

Description

technical field [0001] The invention relates to the field of gas meters, in particular to a gas meter communicating according to power conditions and a remote communication method thereof. Background technique [0002] Civil gas meters are generally powered by batteries. In order to ensure the normal operation of the gas meter’s life cycle, a dual power supply system is adopted. The main power system ensures the normal operation of the gas meter, and the auxiliary power system ensures the basic functions of the gas meter after the main power system fails, such as clock maintenance. etc., but cannot drive high-power functions such as valve operation and remote communication. [0003] Existing IoT gas meters have remote communication functions and can communicate with the gas supplier’s data acquisition system to upload the data in the gas meter, such as cumulative volume, valve status, battery status, etc., and the gas supplier can Obtain the working status of the gas meter,...

AI Technical Summary

Problems solved by technology

[0004] The existing gas meter main power supply system can drive remote communication before it fails to inform the gas supplier that the gas meter main power supply system voltage / power is low, but the battery may be loose or the battery is dialed out during the use of the gas meter. If the main power supply system fails directly, the gas supplier cannot understand the status of the gas meter, nor can it diagnose the cause of the gas meter failure
