Five important components of smart gas

1. Household intelligent gas meter

On the basis of ordinary gas meters, intelligent gas meters, electronic technology and NB Internet of Things network communication technology are used. After the smart gas meter is incorporated into the smart gas system, the user can remotely check the domestic gas through the mobile terminal. Cooperate with the household gas leakage detection alarm device. If the indoor natural gas leakage is detected, the shut-off valve will automatically close. If necessary, users can also cut off indoor gas through mobile phone remote control. Even if they go out, they can deal with abnormal natural gas at home in a timely manner.

2. Gas leakage detection alarm device

Using the gas leakage detection alarm device (hereinafter referred to as the alarm device), once the indoor natural gas concentration is detected to exceed the safety value, the control system inside the sensor will send out an audible and visual alarm synchronously through NB - the Internet of Things network will send the valve closing command to the intelligent gas meter, and send the leakage alarm information to the remote monitoring system of the gas company. After receiving the valve closing command, the intelligent gas meter executes the valve closing operation. After the built-in valve in the intelligent gas meter is closed, it sends a display command to the display module, displaying "the built-in valve is closed", and then feeds back the signal of the built-in valve closing to the alarm through the wireless module.

After receiving the signal of closing valve of intelligent gas meter, the alarm will feed back the alarm information and information of closing valve of intelligent gas meter to the remote monitoring system of gas company. The remote monitoring system of the gas company will send the information to the user's mobile phone and notify the maintenance personnel to arrive at the site at a fast time. If the alarm is connected to the alarm host or 110 alarm receiving center in the community, it can alarm online, and the exhaust equipment and indoor doors and windows can start automatically. After installing the gas leakage detection alarm device, the user can detect whether the natural gas in the home is accidentally leaked in real time to avoid property loss or personal injury caused by gas leakage.

3. Yard management monitoring part

Two methods are adopted for the construction of intelligent gas system: one is to synchronize the video monitoring pictures near the community gas pipeline to the processing platform of the intelligent gas system and the local gas operator, so that the gas company can monitor the soil construction in the community. The second is to embed strain gauges and other sensing elements near the gas pipeline. When there are soil construction operations near the gas pipeline, relevant information will be synchronously transmitted to the processing platform of the intelligent gas system through the network, reminding community workers and gas company employees to supervise the safety protection of the area. Through information sharing and timely notification, gas leakage caused by third-party construction can be effectively prevented.

4. Intelligent voltage regulator

The intelligent pressure regulator is an intelligent product with functions such as indirect flow measurement, local or remote outlet pressure setting, flow restriction, remote monitoring and end user management. The intelligent pressure regulator can automatically adjust the outlet pressure of the pressure regulator according to time or flow, and can remotely monitor the inlet pressure, outlet pressure, cut-off valve position and filtering resistance of the pressure regulator.

The intelligent pressure regulator is configured in the intelligent gas system, which can help operators remotely adjust the pressure of downstream gas to meet the actual needs of remote flow restriction. At the same time, the intelligent pressure regulator can remotely monitor fire or natural gas leakage. In special cases, the natural gas supply can be cut off by remote transmission.

5. Intelligent valve well

Install natural gas detection device and water level detection device in the valve well, and install communication module and anti displacement device on the well cover. The intelligent valve well cover is powered by lithium battery, and the 4G network is used as the communication medium to monitor the gas concentration in the well, the underground water level and the position information of the well cover. Use wireless communication technology to upload data to the processing platform of intelligent gas system. Integrating the management of natural gas valve wells into the intelligent gas system can not only ensure the safety of community gas valve wells to a large extent, but also prevent residents from falling and falling due to abnormal well covers during community activities.
