Description

An intelligent gas meter main board monitoring device

technical field

The invention relates to the technical field of metering instruments, in particular to a monitoring device for a main board of an intelligent gas meter, which can monitor and manage the measurement status of the operation of an intelligent membrane gas meter.

Background technique

With the advancement of science and technology, more and more smart devices are applied to daily life. Various smart gas meters emerged as the times require, including early IC card meters, CPU card meters, radio frequency card meters, later temperature and pressure compensation meters, ultrasonic meters, and MEMS meters, etc. Various smart meters are blooming everywhere in gas companies of all sizes. At the same time, the potential problems of smart membrane gas meters are increasingly exposed. For example, after the main control board fails, the function of the gas meter is out of control. Continuous counting, but the electronic liquid crystal does not work, etc. At the same time, it will cause a large amount of gas loss and management problems caused by the gas supply unit. This has lost its true meaning for using smart gas meters.

Contents of the invention

The purpose of the present invention is to provide an intelligent gas meter main board monitoring device, which can monitor the operating status of the gas meter. Gas company losses and resulting management issues.

The technical solutions adopted are:

An intelligent gas meter main board monitoring device comprises an electromechanical conversion module, a main control board, an intelligent monitoring module, a motor valve and a display module. The electromechanical conversion module is installed on the mechanical counter of the base meter or on other modules that can regularly reflect the measurement characteristics, and is used to collect the mechanical pulse signal of the base meter, convert it into an electrical signal, and transmit it to the main control board and Intelligent monitoring module. The main control board is installed on the housing of the base meter. According to different requirements, the main control board has functions such as prepayment, temperature and pressure compensation, valve control, and remote transmission. The main control board can drive the display module to display the metering volume, drive the motor valve, and realize the opening and closing of the gas passage. The intelligent monitoring module is also installed on the housing of the base meter, and is used to receive signals from the electrical conversion module and the main control board and carry out accumulative comparison. At the same time, the motor valve is driven in time to control the opening and closing of the gas passage. The intelligent monitoring module has an independent power supply system, which can still drive the motor valve when the main control board fails.

Advantages of the present invention:

The smart gas meter main board monitoring device can monitor the operating status of the gas meter in real time. When the main control board fails, it can still drive the motor valve to cut off the gas passage, reduce the phenomenon of gas loss, and protect the interests of the gas company to the greatest extent. The intelligent monitoring module adopts a low-power design, and the average working current is below 2uA, which is negligible for the smart gas meter as a whole.
