Description

Smart gas monitoring device

The invention relates to a monitoring device of a microcomputer gas meter, in particular to a smart gas monitoring device which can integrate sensors and smart monitors into one, to achieve the convenience of installation and the efficiency of smart monitoring.

Although the traditional mechanical gas meters can calculate the user's gas usage, the work of obtaining the user's gas usage every month or every two months still needs to rely on a lot of manpower to read the meter one by one, and then complete the billing and charging according to the meter Operations, the entire process is time-consuming, prone to disputes, has a high rate of human error, and requires a lot of labor costs.

On the other hand, the traditional mechanical gas meters can only calculate the gas usage degree, and there is no function to automatically cut off the gas supply. In case of gas leakage, excessive concentration of carbon monoxide (CO) or earthquake disaster, the safety of users cannot be guaranteed. Therefore, the Energy Bureau of the Ministry of Economic Affairs started to promote microcomputer gas meters with automatic cut-off function in 2014.

Existing microcomputer gas meters are different from traditional mechanical gas meters with only measurement functions. Known microcomputer gas meters have several security protection functions, including: leak detection protection, carbon monoxide detection protection and earthquake interruption. The structure of the known microcomputer gas meter includes at least: a shut-off valve, a built-in power supply, a shock sensor, a flow sensor, a microcomputer chip, a pressure sensor, a measuring part, a measuring indicator and a reset device, which can be connected to external gas The leak detection sensor and the carbon monoxide sensor, through the above structure, the microcomputer gas meter further reaches the following five Big function:

1. It can automatically shut off gas when an earthquake or pipeline breaks.

2. It has a simulated situation, such as automatic gas interruption function that exceeds the preset safe use time.

3. It has the function of automatically shutting off gas for over-flow or leak detection.

4. Detect gas (GAS) gas leakage and activate the automatic gas shut-off function.

5. It has the functions of detecting carbon monoxide (CO) and starting to automatically cut off gas.

In order to solve the problem of traditional mechanical gas meters relying on manual meter reading, the approved Taiwan new patent certificate number TW M484138U proposes a "cloud gas meter management service system". The main purpose is to set the gas meter with built-in authentication code (ID) and the corresponding communication sub-machine on the user side, so that the gas consumption of the user side and the operation status of the gas meter are monitored by a gas meter communication platform with a cloud backend and database And record, and the server can set up a backstage with management interface, after verifying with the installed gas meter, enter the gas meter communication platform to read the related information of the installed gas meter to complete the remote gas The operations of meter reading, periodic testing or notification service, etc., achieve the purpose of reducing the cost of manual meter reading and the rate of human error.
