In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0046] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0047] Figure 1 This is a schematic diagram of the structure of a natural gas periodic inspection system 10 provided in an embodiment of the present disclosure. Figure 1 The natural gas periodic inspection system 10 comprises:

[0048] A first acquisition module 11, a second acquisition module 12, a first switch module 13, a control module 14, a gateway 15, a detection module 16 and an IC module 17;

[0049] The first acquisition module 11 and the gateway 15 are both connected to the control module 14, and the second acquisition module 12 is connected to the control module 14 via the first switch module 13;

[0050] The detection module 16 has a first end connected to the first switch module 13, a second end connected to the gateway 15, and a third end connected to the IC module 17; the gateway 15 is also used to connect to the monitoring terminal 18;

[0051] The first acquisition module 11 is configured to acquire natural gas parameters in the target area; the second acquisition module 12 is configured to acquire environmental parameters including natural gas parameters in the target area;

[0052] The control module 14 is configured to analyze and send natural gas parameters and environmental parameters to the gateway 15; the gateway 15 is configured to receive and send a first wake-up signal from the monitoring terminal 18 to the control module 14 and the detection module 16;

[0053] The IC module 17 is configured to receive an external second wake-up signal and send it to the detection module 16;

[0054] The detection module 16 is configured to control the working state of the first switch module 13 according to the first wake-up signal and the second wake-up signal.

[0055] In this embodiment, the first acquisition module 11 can collect natural gas related parameters in the target area, such as pressure, flow, gas composition and other data, and send these data to the control module 14 for analysis and processing. The target area can be a natural gas transmission pipeline, storage facilities, gas stations and related equipment and systems. In addition to collecting natural gas parameters in the target area, the second acquisition module 12 can also collect temperature, humidity and other related data in the target area.

[0056] The second acquisition module 12 is generally in a dormant state. When the first switch module 13 is turned on, the second acquisition module 12 is awakened and can collect the above data and send it to the control module 14 through the first switch module 13 .

[0057] The first switch module 13, as a key element for controlling the data transmission of the second acquisition module 12, has its working state controlled by the detection module 16 according to the received wake-up signal. The first switch module 13 is generally in an off state. When the detection module 16 receives the wake-up signal, it will control the first switch module 13 to turn on accordingly, thereby controlling the transmission of data of the second acquisition module 12.

[0058] The detection module 16 can receive the first wake-up signal from the monitoring terminal 18 forwarded by the gateway 15 and the second wake-up signal sent by the IC module 17, and control the working state of the first switch module 13 according to the two wake-up signals. The first switch module 13 can be a logic gate, a comparison circuit, etc. When the first switch module 13 is an "OR" gate, the first switch module 13 can be turned on when it receives any wake-up signal. The first wake-up signal can be a regular wake-up signal set by the monitoring terminal 18. For example, the first wake-up signal is sent to the gateway 15 every hour, and the gateway 15 forwards this signal to the detection module 16 and the control module 14.

[0059] The IC module 17 can receive an external second wake-up signal and send the signal to the detection module 16. The IC module 17 can be various card readers. The second wake-up signal can be a signal generated by a technician who detects the safety status of natural gas using a work card or other control card to swipe the card reader during an inspection.

[0060] The control module 14 can receive and process the data collected by the first collection module 11 and the second collection module 12, and send the data to the gateway 15. At the same time, the control module 14 can also respond to the first wake-up signal of the monitoring terminal 18 sent from the gateway 15.

[0061] The gateway 15 can receive data sent by the first acquisition module 11 and the second acquisition module 12, and send the data to the remote monitoring terminal 18. The gateway 15 can also receive a first wake-up signal from the control terminal, and forward it to the control module 14 and the detection module 16.

[0062] In this embodiment, due to the complex geographical environment in rural areas, the scattered layout of pipelines, the difficulty in maintaining facilities, and the users' insufficient knowledge of the safe use of natural gas and lack of necessary safety awareness, it is easy for users to have safety hazards during use. Therefore, the present disclosure can realize regular inspections of natural gas, identify safety hazards, and ensure the stability and reliability of natural gas supply.

[0063] In this embodiment, the first acquisition module 11 is usually in a normally open state, and will regularly send the pressure, flow, and gas composition data in the natural gas pipeline in the target area to the control module 14, and the control module 14 will send it to the monitoring terminal 18 through the gateway 15. If the monitoring terminal 18 determines that the data collected by the first acquisition module 11 is within the normal range, but there is an abnormal change trend, it can send a first wake-up signal to the gateway 15, and the gateway 15 will forward the signal to the control module 14 and the detection module 16. Or the technician directly sends a second wake-up signal to the detection module 16 through the IC module 17. After receiving the first wake-up signal or the second wake-up signal, the control module 14 enters a waiting state for data reception. The detection module 16 outputs a corresponding control instruction according to the first wake-up signal or the second wake-up signal to control the first light-on module to turn on. At this time, the second acquisition module 12 starts to work and sends the collected data such as pressure, flow, gas composition, temperature, humidity, etc. in the natural gas pipeline to the control module 14. The control module 14 sends the data to the gateway 15 after preliminary processing, and the gateway 15 sends the data to the monitoring terminal 18.

[0064] It can be concluded from the above that, in general, the first acquisition module 11 in the present disclosure is in a working state for a long time, and the second acquisition module 12 and the first switch module 13 are in a closed state. The first switch module 13 enters the working state only after receiving a wake-up signal sent by the monitoring terminal 18 or the technician through the IC module 17. Therefore, the present disclosure reduces the cost of equipment maintenance, reduces equipment energy consumption, and can realize regular inspections of places such as natural gas pipelines.

[0065] In one embodiment of the present disclosure, the first acquisition module 11 includes:

[0066] A first pressure detection unit 101, a first flow detection unit 102 and a first gas component detection unit 103;

[0067] The first pressure detection unit 101 , the first flow detection unit 102 , and the first gas component detection unit 103 are all connected to the control module 14 .

[0068] In this embodiment, the first pressure detection unit 101 can detect the pressure of the natural gas pipeline or storage tank in the target area to ensure that it is within a safe range. Too high or too low pressure may indicate potential problems or risks. The first pressure detection unit 101 monitors the pressure data in real time and sends the data to the control module 14 for analysis and processing. The first pressure detection unit 101 can be a mechanical pressure gauge, an electronic pressure transmitter, a pressure sensor, and other equipment.

[0069] The first flow detection unit 102 can be used to measure the flow of natural gas, which is crucial for monitoring the efficiency of natural gas use, metering costs, and troubleshooting leaks. The first flow detection unit 102 transmits the collected flow data to the control module 14 in real time. The first flow detection unit 102 can be a turbine flow meter, ultrasonic flow meter, etc.

[0070] The first gas component detection unit 103 can analyze the components in natural gas, such as the ratio of methane, ethane, nitrogen, carbon dioxide, etc., to ensure that the quality of natural gas meets the specified standards and can promptly detect harmful impurities or abnormal gas ratios. The first gas component detection unit 103 sends the detected data to the control module 14. The first gas component detection unit 103 can be an infrared gas analyzer, a gas chromatograph, and other equipment.

[0071] From the above, it can be concluded that the three detection units can send their respective detected data to the control module 14 for unified analysis and processing by connecting to the control module 14, so that the control module 14 can fully grasp the key parameters of natural gas in the target area, thereby realizing all-round and multi-dimensional regular inspection and monitoring of the natural gas system.

[0072] In one embodiment of the present disclosure, the second acquisition module 12 includes:

[0073] A second pressure detection unit 201, a second flow detection unit 202, a second gas component detection unit 203, a temperature detection unit 204 and a humidity detection unit 205;

[0074] The second pressure detection unit 201 , the second flow detection unit 202 , the second gas component detection unit 203 , the temperature detection unit 204 , and the humidity detection unit 205 are all connected to the control module 14 .

[0075] In this embodiment, the second pressure detection unit 201 has the same function as the first pressure detection unit 101 and can independently detect the natural gas pressure in the target area, providing double insurance to ensure data accuracy and send the data to the control module 14 .

[0076] The second flow detection unit 202 has the same function as the first flow detection unit 102 and can perform secondary detection on the flow rate of natural gas to verify and supplement the flow data and ensure the reliability of flow measurement.

[0077] The second gas component detection unit 203 is the same as the first gas component detection unit 103 and can independently detect the component ratio in natural gas to verify the data of the first gas component detection unit 103 and provide more detailed or backup gas component information.

[0078] The temperature detection unit 204 can detect the ambient temperature in the target area or the temperature of the natural gas itself, which is important for evaluating the physical state, safe transportation and combustion efficiency of the natural gas. The temperature detection unit 204 can be a temperature sensor.

[0079] The humidity detection unit 205 is used to monitor the humidity level in the target area, which is important for determining whether the environmental conditions cause corrosion to the natural gas pipeline or equipment, affect the combustion performance of the natural gas, and ensure the safe operation of the system as a whole. The humidity detection unit 205 can be a humidity sensor.

[0080] It can be concluded from the above that these detection units can send the collected data to the control module 14 so that the system can conduct comprehensive analysis, comparison, judgment and decision-making, thereby realizing more comprehensive and in-depth monitoring and control of the natural gas system. Because the second acquisition module 12 adds temperature and humidity detection compared to the first acquisition module 11, the collected data is more comprehensive, thereby enhancing the safety and reliability of system operation.

[0081] In one embodiment of the present disclosure, the detection module 16 includes:

[0082] Logic gate unit 301 and control unit 302;

[0083] The logic gate unit 301 is connected to the gateway 15, the IC module 17, and the control unit 302 respectively, and the control unit 302 is connected to the first switch module 13;

[0084] The logic gate unit 301 is configured to receive signals from the gateway 15 and the IC module 17 and send output signals to the control unit 302;

[0085] The control unit 302 is configured to control the working state of the first switch module 13 according to the signal sent by the logic gate unit 301 .

[0086] In this embodiment, the logic gate unit 301 can receive signals from the gateway 15 and the IC module 17. The gateway 15 sends the first wake-up signal of the monitoring terminal 18 or the status signal of the system, while the IC module 17 may transmit the external second wake-up signal or other control signal. The logic gate unit 301 analyzes and processes these signals according to the preset logical relationship to generate corresponding output signals. For example, the logic gate unit 301 can be an OR gate, that is, any wake-up signal can turn on the first switch module 13.

[0087] The control unit 302 receives the signals output by the logic gate unit 301, and can analyze these signals and formulate corresponding control strategies. The control unit 302 can control the working state of the first switch module 13 according to the output signal of the logic gate unit 301, such as turning on, off or switching to a specific working mode.

[0088] From the above, it can be concluded that the detection module 16 can effectively integrate the signals from the IC module 17 and the monitoring terminal 18, and make a comprehensive judgment based on the preset logic, so as to control the working state of the first switch module 13, and ensure that the natural gas periodic inspection system 10 can correctly and efficiently perform the corresponding operations when specific conditions are met.

The alarm module 19 is connected to the control module 14 and can receive the alarm instruction or status information issued by the control module 14, thereby executing the corresponding alarm action.

[0093] For example, when the control module 14 determines that there are potential risks such as excessive natural gas concentration or abnormal drop in pipeline pressure, the control alarm module 19 activates various forms of warning measures such as sound and light alarms, SMS notifications, and remote communications to promptly remind relevant personnel to take countermeasures to ensure the safe operation of the system and the normal and orderly supply of natural gas.

[0094] In one embodiment of the present disclosure, the natural gas periodic inspection system 10 further includes:

[0095] Camera module 20 and display module 21;

[0096] The camera module 20 is connected to the display module 21;

[0097] The camera module 20 and the display module 21 are both connected to the control module 14 .

[0098] In this embodiment, the camera module 20 can monitor and record the status of the natural gas pipeline, equipment and surrounding environment in real time. The camera module 20 may include one or more cameras, which can be activated at a specific time point or when receiving instructions from the control module 14 to collect video data on site. Video data can help staff remotely observe the operating status of natural gas facilities, check for leaks, damage or other safety hazards, and also provide evidence for subsequent fault analysis and processing.

[0099] The display module 21 can present the video information and other key data (such as natural gas pressure, flow, gas composition detection results, etc.) obtained from the camera module 20 in a visual manner. The display module 21 can be a display, touch screen or other display device, which is convenient for the on-site operator or the staff of the remote monitoring center to check and monitor the system operation status at any time. At the same time, when an abnormal situation occurs in the system, the display module 21 can also display the corresponding warning information according to the instructions of the control module 14.

[0105] In this embodiment, the second switch module 22 is in an open state for a long time, so that the data collected by the first acquisition module 11 can be safely sent to the control module 14. When the second acquisition module 12 starts working, in order to reduce system power consumption, the monitoring terminal 18 can send an instruction to the detection module 16, and after receiving the instruction, the detection module 16 sends a closing signal to the second switch module 22 to control the second switch module 22 to close.

[0106] It can be concluded from the above that the second switch module 22 is provided so that when the second acquisition module 12 is working, the first acquisition module 11 is turned off, which helps to reduce system power consumption and save energy.
