A smart gas meter system that facilitates data reading in data centers

Abstract

The invention discloses an intelligent gas meter system providing convenience for a data center to read data, and relates to the technical field of intelligent gas meter electronics. The intelligent gas meter system comprises two intelligent gas meters, and each intelligent gas meter comprises a first data transmission module, a second data transmission module, a power supply module, a low voltagedetection module, a clock circuit module, an MCU control module, a control valve driving module and a control valve. By means of the intelligent gas meter system, the situation is prevented that under the condition that a user does not use an intelligent gas meter for a long time, a built-in power supply, namely a lithium battery is in a sleep state; when the lithium battery works in a low current state for a long time and the voltage of the lithium battery is lower than a certain threshold valve, the MCU control module sends a signal to the control valve driving module to control the controlvalve to be switched on to wake up the lithium battery; meanwhile, the intelligent gas meter system solves the problems that since data transmission modules in existing intelligent gas meters usuallyhave signal transmission blind spots, gas companies cannot read data in the gas meters and cannot accurately monitor the gas meters.

Description

technical field [0001] The invention relates to the electronic technical field of intelligent gas meters, in particular to an intelligent gas meter system which is convenient for a data center to read data. Background technique [0002] Ordinary household membrane gas meters, due to the difficulty of charging, the high labor costs of meter readers, and the inability to monitor gas theft, have continuously increased operating costs for gas companies and brought many troubles to operation and management. Therefore, since 1995 At the beginning, various smart gas meters gradually appeared on the market, in order to solve the headaches encountered in the operation of gas companies. IC card meters, CPU card smart gas meters, wired remote gas meters, wireless remote gas meters, network infrared digital gas meters and other varieties have emerged one after another. At present, domestic smart gas meters mainly include IC card smart gas meters, CPU card smart gas meters, radio freque...

Problems solved by technology

[0006] The purpose of the present invention is: it can be seen from the background technology that there are two problems in the existing smart gas meter: (1) when the smart gas meter is not in use for a long time, the electric quantity inside the lithium battery inside the built-in power supply will decrease Gradually attenuate, when the smart gas meter is used again, the current provided by the lithium battery will decrease, and the data transmission module will not be able to transmit the data to the data center of the gas company; (2) The data transmission module usually has a signal transmission blind spot, As a result, the transmission signal is unstable, and the GPRS data transmission module will not be able to communicate better with the base station, causing the gas company to be unable to read the data inside the gas meter; in order to solve these two problems, the present invention provides a convenient data center Smart gas meter system for reading data
