Today, I will introduce a national invention authorized patent-a gas meter with real-time detection of valve action. The patent was applied for by Haiyan Xingchuang Electronics Co., Ltd., and the authorization was announced on February 13, 2018.
Content descriptionThe invention relates to the technical field of IC card gas meters, in particular to a gas meter with the function of real-time detection of valve action.
Background of the inventionIC card gas meter, with automatic charging function, one meter and one card for each household, the user transfers the cost to the gas management department, the management department writes the gas purchase amount into the IC card through the computer management system, and the user inserts the IC card into the IC card for gas In the table, you can obtain the usage rights of the purchased gas. In the process of gas consumption by the user, the microcomputer in the IC card smart meter automatically reduces the remaining gas volume. When the purchased gas volume is used up, the valve will be automatically closed and the gas will be shut off. The user needs to purchase the gas again to enable the IC card gas meter to open the valve and supply gas again . The IC card can also record the operation of the gas meter, and manage the total gas consumption, total gas purchase, and on-off valve status of the meter under the management machine or management software. IC card gas meters can improve management efficiency, effectively prevent arrears, and avoid meter reading. It is suitable for measuring the flow of natural gas and coal gas. The IC card gas meter with gas leakage alarm function can monitor the gas leakage in the meter. When the combustible gas in the meter leaks, the combustible gas detector of the gas meter will give out an audible and visual alarm, and the LCD screen in the meter will also display Alarm information, and automatically close the valve to achieve the effect of ensuring the safety of people's lives and property.
The IC card gas meter controls the internal valves on and off. The normal operation of the internal valves of the gas meter directly affects the normal operation of the gas meter. With the gradual promotion and application of IC card prepaid gas meters, whether the internal valve function of the IC card gas meter works normally has a direct impact on whether the gas meter can be used normally. Once the internal valve fails to work normally, it will directly lead to the use of the gas meter. People's daily life and gas management. Therefore, it is necessary to propose a gas meter with the function of real-time detection of valve action.
Summary of the inventionIn view of the shortcomings of the prior art, the present invention provides a gas meter with the function of real-time detection of valve action, which aims to solve whether the internal valve function of the IC card gas meter in the prior art directly affects the normal use of the gas meter. Once the internal valve fails to work normally, it will directly lead to the use of gas meters, affecting people's daily life and technical problems in gas management.

The figure is a block diagram of a gas meter with the function of real-time detection of valve action according to an embodiment of the present invention
To achieve the above objective, the present invention proposes a gas meter with the function of real-time detection of valve action, including a base meter and a controller connected to the base meter. The base meter is provided with a gas source input port and a gas source output port. An organic electric valve is also set inside. The input and output of the electromechanical valve are respectively connected to the air source input port and the air source output port. The controller includes a CPU main control module, a power supply module, an electromechanical valve control module, an IC card read-write module, and a metering Sampling module, current monitoring module, signal processing module and display module. The CPU main control module drives and controls the electromechanical valve in the base meter through the electromechanical valve control module. The CPU main control module is connected to the base meter through the metering sampling module.
Preferably, the power supply module provides power for the CPU main control module, electromechanical valve control module, IC card reading and writing module, metering sampling module, current monitoring module, signal processing module, display module and electromechanical valve, electromechanical valve control module, IC The card reading and writing module, measurement sampling module and display module are all communicatively connected with the CPU main control module. The current monitoring module is connected to the power supply module to monitor and collect the current signal of the power supply module in real time. The current monitoring module communicates with the CPU main control module through the signal processing module Communication connection.
An IC card socket is arranged on the controller, and the IC card socket is connected with the IC card reading and writing module. The controller also includes an alarm, which communicates with the CPU main control module. The controller also includes a remote communication module, and the CPU main control module communicates with the computer management system through the remote communication module. A manual valve is also set on the base meter, and the manual valve is set at the air source input port. A display screen is arranged on the base meter, and the display screen is connected with the display module. A metering sensor is arranged on the base meter, and the metering sensor is connected with the metering sampling module.
The beneficial effects of the present invention: Compared with the prior art, the present invention provides a gas meter with the function of real-time detection of valve action. The structure is reasonable. The current monitoring module is used to monitor the power consumption current signal of the gas meter in real time. The processing module processes the signal and sends it to the CPU main control module. The CPU main control module compares the collected current signal with the current threshold set in the CPU main control module. Once an abnormal situation is found, the CPU main control module The control module will control the alarm to give an alarm, and the abnormal current signal can be fed back to the computer management system through the remote communication module to find the problem in time, which helps to better supervise the normal operation of the electromechanical valve and ensure the normal supply of gas.
