Description

A remote monitoring system based on Internet pipe network

technical field

The utility model relates to the field of monitoring systems, in particular to a remote monitoring system based on Internet pipe networks.

Background technique

With the adjustment of the national energy planning structure and the gradual improvement of people's living standards, gas has become an important energy source for national production and life. The main consumption terminals of gas are many cities, the gas supply pipeline network is mainly concentrated in densely populated areas, the main pipeline is mainly laid underground on the road, and the branch network is distributed in buildings and indoors. However, leaks caused by corrosion, cracks and other reasons occur frequently. In the slightest, it will cause resource waste and environmental pollution, and in severe cases, it will cause explosions, fires, and poisoning, endangering the lives and property safety of users and surrounding populations. It has brought immeasurable losses to the society. The leak repair and regular security inspection of the gas pipeline network have been highly valued by people. The leak location detection instrument can play an irreplaceable role in the repair, security check and accident handling. However, the automatic early warning and monitoring of the existing gas pipelines is still in the passive and independent monitoring stage, with problems such as inaccurate positioning, untimely alarm, and inability to network data sharing. Moreover, when encountering sudden abnormalities, there is no effective means of remote operation to reduce risks.

Utility model content

In order to achieve this technical purpose, the solution of this utility model is: a remote monitoring system based on the Internet pipe network, including an urban pipe network, a central base station, and a monitoring module. The urban pipe network includes a plurality of pipeline nodes. A monitoring module is provided on the pipeline node, and the monitoring module includes a gas leakage monitoring module, a communication module, an MCU and a pressure sensor. The gas leakage monitoring module, the communication module and the pressure sensor are respectively electrically connected to the MCU, and the monitoring module is connected Communication connection between central base stations;

The MCU is also electrically connected with an audible and visual alarm module, and the audible and visual alarm module includes a buzzer and an LED fault indication diagram.

Preferably, the monitoring module is also electrically connected with an electromagnetic shut-off valve, and the electromagnetic shut-off valve is arranged on a pipeline node.

Preferably, the gas leakage monitoring module is a methane sensor.

Preferably, the MCU is also electrically connected to a ventilation module.

The beneficial effect of the utility model is that through the data transmission and communication between the monitoring module and the central base station through the Internet, the central base station can obtain the gas leakage situation and gas pressure situation of each node in real time, and then realize real-time monitoring; The electromagnetic shut-off valve can actively open or close the designated valve; when the methane concentration is abnormal, forced ventilation is performed through the ventilation module, which can reduce the methane concentration in the environment and reduce the risk of explosion.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, the specific embodiment of the utility model is a remote monitoring system based on the Internet pipe network, including an urban pipe network, a central base station, and a monitoring module, and the urban pipe network includes a plurality of pipeline nodes , the pipeline node is provided with a monitoring module, the monitoring module includes a gas leakage monitoring module, a communication module, an MCU, and a pressure sensor, and the gas leakage monitoring module, communication module, and pressure sensor are respectively electrically connected to the MCU, and the The monitoring module is connected to the central base station by communication; the MCU is also electrically connected to an audible and visual alarm module, and the audible and visual alarm module includes a buzzer and an LED fault indication diagram. Through the data transmission and communication between the monitoring module and the central base station through the Internet, the central base station can obtain the gas leakage and gas pressure of each node in real time, and then realize real-time monitoring.

The designated valve can be actively opened or closed through the electromagnetic shut-off valve, and the monitoring module is also electrically connected with the electromagnetic shut-off valve, and the electromagnetic shut-off valve is arranged on the pipeline node. When an abnormality is found, the central base station can be connected with the monitoring module through the data transmission communication of the Internet, and the designated valve can be opened or closed actively through the electromagnetic shut-off valve.

Since the main component of the gas is methane, the gas leakage monitoring module is a methane sensor. The methane sensor can accurately detect the methane content in the air, and can effectively and timely detect leakage.

Since the combustion or explosion of methane in the air needs to reach a certain concentration, the MCU is also electrically connected to a ventilation module. When the concentration of methane is abnormal, forced ventilation through the ventilation module can reduce the concentration of methane in the environment and reduce the risk of explosion.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any minor modifications, equivalent replacements and improvements made to the above embodiments according to the technical essence of the present utility model shall be included in the Within the scope of protection of the technical solution of the utility model.
