Description

Technical Field

[0001] This utility model relates to the field of geological monitoring technology around natural gas pipelines, specifically a geological disaster monitoring and early warning system around natural gas pipelines. Background Technology

[0002] Natural gas pipelines pass through mountainous and hilly areas, where landslides and rockfalls frequently occur due to concentrated rainfall (heavy rain). Although design specifications clearly state that pipeline laying should avoid mountainous areas with geological disaster risks as much as possible, due to the influence of local economic development or the lack of awareness of geological disaster risks among designers, some natural gas pipelines have passed through potential landslide areas, posing safety hazards such as pipeline cracking, deformation, and leakage due to large landslides.

[0003] Traditional monitoring of geological hazards around natural gas pipelines currently relies on manual inspections and on-site measurements with instruments. Data is then manually compiled and reported for analysis. This method is insufficient for long-term real-time monitoring and timely access to geological information, leading to delayed or inaccurate early warnings for many geological hazards. Furthermore, inspections in mountainous and hilly areas are challenging and physically demanding for staff. Utility Model Content

[0004] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide a geological disaster monitoring and early warning system around natural gas pipelines.

[0005] A geological disaster monitoring and early warning system for natural gas pipelines includes a rain gauge, a GNSS displacement monitor, a crack gauge, a soil moisture meter, an inclinometer, a pipeline surface strain gauge, and a video surveillance camera. The rain gauge monitors rainfall on slopes along the natural gas pipeline route. The GNSS displacement monitor monitors landslides on these slopes. The crack gauge monitors the depth, width, length, and opening / closing of cracks on the slopes along the natural gas pipeline route. The soil moisture meter monitors the moisture content of the soil along the natural gas pipeline route. The inclinometer monitors changes in the tilt angle of the slopes along the natural gas pipeline route. The pipeline surface strain gauge monitors deformation and stress changes in the natural gas pipeline. The rain gauge, GNSS displacement monitor, crack gauge, soil moisture meter, inclinometer, and pipeline surface strain gauge are connected to a wireless data transmission module via an RS485 communication interface. The wireless data transmission module communicates with a remote monitoring center. The video surveillance camera monitors real-time changes in the environment surrounding the natural gas pipeline. The video surveillance camera communicates with a video monitoring server via a microwave communication transmitter module. The video monitoring server is connected to the remote monitoring center via a network cable.

[0006] A further option is that the wireless data transmission module includes a GPRS communication module.

[0007] A further embodiment is that the remote monitoring center includes a communication module, a data processing module, and a geological disaster early warning module. The communication module is used to establish a communication connection with the wireless data transmission module based on a wireless communication protocol. The data processing module is used to process the received monitoring parameters and generate a trend chart of parameter information changes. The geological disaster early warning module is used to issue geological disaster early warning information for monitoring parameters that exceed the set early warning value.

[0008] A further solution includes a power supply module and a battery. The power supply module is connected to the battery, which powers the rain gauge, GNSS displacement monitor, crack gauge, soil moisture meter, inclinometer, pipe surface strain gauge, and video surveillance camera.

[0009] A further embodiment is that the power supply module includes a photovoltaic panel, a wind generator, and a wind-solar hybrid controller. One end of the wind-solar hybrid controller is connected to the photovoltaic panel and the wind generator, and the other end of the wind-solar hybrid controller is connected to a battery.

[0010] A further embodiment is that the wind turbine drives the magnetic rotor to rotate through the blades, thereby generating alternating current in the winding coil. The winding coil is then connected to a rectifier and a voltage regulator in sequence via wires, and finally connected to the wind-solar hybrid controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses rain gauges, GNSS displacement monitors, crack gauges, soil moisture meters, inclinometers and pipeline surface strain gauges to monitor the rainfall, slope displacement, depth, width, length and opening degree of cracks on the slope of the natural gas pipeline, and changes in the tilt angle of the slope of the natural gas pipeline in real time. The data is transmitted to the remote monitoring center through a wireless data transmission module, so that the geological disaster situation around the natural gas pipeline can be monitored and warned remotely in real time. This solves the problems of difficulty in long-term real-time monitoring and high inspection difficulty and labor intensity of staff by manual inspection. The auxiliary video monitoring camera monitors the changes in the environment around the natural gas pipeline in real time, which can more accurately understand the geological information around the natural gas pipeline.

[0012] (2) When the sun is shining during the day, the photovoltaic panel converts solar energy into electrical energy and stores it in the battery; at night or when there is no sun, wind energy serves as a supplementary energy source, ensuring that power can be supplied independently in remote mountainous and hilly areas without relying on the mains power.

[0019] sensor;

[0020] 7 video surveillance cameras;

[0021] Wireless data transmission module 8;

[0022] Microwave communication transmitting module 9;

[0023] Remote monitoring center 10;

[0026] The sensors are arranged within a preset distance on both sides of the natural gas pipeline; in this embodiment, the preset distance is preferably within 10 meters. The sensors include a rain gauge 1, a GNSS displacement monitor 2, a crack gauge 3, a soil moisture meter 4, an inclinometer 5, and a pipeline surface strain gauge 6. The rain gauge 1 is used to monitor rainfall on the slope along which the natural gas pipeline passes. The GNSS displacement monitor 2 utilizes Global Navigation Satellite System (GNSS) technology to monitor the displacement of the slope along which the natural gas pipeline passes in real time with high precision. Whether it is a landslide, debris flow, or ground subsidence, the GNSS displacement monitor 2 can detect and issue early warnings. The working principle of the GNSS displacement monitor 2 is based on satellite signal reception and processing. Through differential positioning technology, combined with reference station data of known precise locations, the positioning data of the monitoring point is corrected to achieve millimeter-level monitoring accuracy. It should be noted that the real-time, high-precision monitoring of slope displacement by the GNSS displacement monitor 2 is existing technology, and the specific implementation process will not be elaborated here. The crack gauge 3 is used to monitor parameters such as the depth, width, length, and opening degree of cracks on the slope along which the natural gas pipeline passes. The crack gauge 3 can sense minute displacements or deformations of cracks and convert these physical changes into electrical signals. The corresponding data processing unit receives these signals, filters, amplifies, and digitizes them to obtain precise crack parameters. These precise parameters can be remotely transmitted to the remote monitoring center 10 for real-time viewing and analysis by management personnel. The crack gauge 3's monitoring of the depth, width, length, and opening / closing of surface cracks around the natural gas pipeline is also existing technology; the specific implementation process will not be detailed here. The soil moisture meter 4 is used to monitor the moisture content of the soil along the natural gas pipeline route. The inclinometer 5 is used to monitor changes in the inclination angle of the slope along the natural gas pipeline route. The inclinometer 5 is installed on the slope along the natural gas pipeline route. The inclinometer 5's working principle is based on gravity sensing or accelerometer principles. The inclinometer 5 can be used to measure the inclination angle of slopes, thereby assessing slope stability and providing important information for preventing slope instability. The inclinometer 5's monitoring of changes in the slope inclination angle is also existing technology; the specific implementation process will not be detailed here. The pipe surface strain gauge 6 is fixed to the natural gas pipeline by spot welding or adhesive bonding. The pipe surface strain gauge 6 is used to monitor the deformation and stress changes of the natural gas pipeline when subjected to external forces. The video surveillance camera 7 is used to monitor changes in the surrounding environment of the natural gas pipeline in real time.

[0027] The wireless data transmission module 8 is connected to the rain gauge 1, GNSS displacement monitor 2, crack gauge 3, soil moisture meter 4, inclinometer 5, and pipeline surface strain gauge 6 via an RS485 communication interface. The wireless data transmission module 8 transmits monitoring parameters such as rainfall information, slope displacement information, depth, width, length, and opening / closing degree of cracks on the surface around the natural gas pipeline, soil moisture content information, and angle changes of the slope where the natural gas pipeline is located to the remote monitoring center 10. The wireless data transmission module 8 includes at least a GPRS communication module.

[0028] The microwave communication transmitting module 9 is used to transmit the on-site video monitoring parameters captured by the video surveillance camera 7 to the video surveillance server 11 via microwave communication system.

[0029] The remote monitoring center 10 includes a communication module, a data processing module, and a geological disaster early warning module. The communication module establishes a communication connection with the wireless data transmission module 8 based on a wireless communication protocol. The data processing module processes the received monitoring data to generate trend graphs of monitoring parameters such as slope displacement, crack depth, width, length, and slope angle. The geological disaster early warning module analyzes the trends of these parameters and, in conjunction with historical statistical data of the monitored area, issues geological disaster early warnings for changes in slope displacement, crack depth, width, length, and slope angle that exceed set warning values. If the set warning values ​​are exceeded, it indicates an anomaly.

[0030] The video monitoring server 11 is used to receive and store the on-site video monitoring parameters transmitted by the microwave communication transmitting module 9. The video monitoring server 11 is connected to the remote monitoring center 10 via a network cable and can provide the video monitoring parameters when accessed by authorized Internet computer users.

[0031] The power supply module 12 is connected to the storage battery 13, which powers field equipment such as the rain gauge 1, GNSS displacement monitor 2, crack gauge 3, soil moisture meter 4, inclinometer 5, pipe surface strain gauge 6, and video surveillance camera 7. The power supply module 12 includes a photovoltaic panel 121, a wind turbine generator 122, and a wind-solar hybrid controller 123. One end of the wind-solar hybrid controller 123 is connected to the photovoltaic panel 121 and the wind turbine generator 122, and the other end is connected to the storage battery 13. The photovoltaic panel 121 generates solar power, while the wind turbine generator 122 generates wind power. During the day, when the sun is out, the photovoltaic panel 121 converts solar energy into electrical energy and stores it in the storage battery 13. At night or when there is no sun, wind power serves as a supplementary energy source, ensuring independent power supply even in remote mountainous and hilly areas, without relying on mains power. The wind turbine 122 drives the magnetic rotor to rotate through the wind blades, which causes the winding coil to generate alternating current. The winding coil is connected to the rectifier and the voltage regulator in sequence through wires and then connected to the wind-solar hybrid controller 123.
