Description

Technical Field

[0001] This invention relates to the field of natural gas pipeline monitoring technology, and in particular to a natural gas pipeline safety monitoring and alarm system. Background Technology

[0002] The gas alarm system installed by the natural gas equipment engineering company can only work on-site and cannot be monitored remotely via the network; the maintenance company does not understand the working condition of the equipment. Gas detectors and probes have a lifespan and will fail or malfunction after a period of time. The alarm monitoring host may also be damaged and unable to monitor normally. Sending engineers to conduct regular on-site inspections is time-consuming and labor-intensive.

[0003] For example, Chinese invention patent CN109140247A discloses a remote monitoring system for natural gas pipeline leaks, including an on-site detection device and a remote monitoring center. The on-site detection device includes a fiber optic grating sensor, a fiber optic grating sensor network analyzer, a monitoring computer, and a wireless communication module. The fiber optic grating sensor is positioned directly above the natural gas pipeline and is connected to the fiber optic grating sensor network analyzer via optical fiber. The fiber optic grating sensor network analyzer and the wireless communication module are respectively connected to the monitoring computer to achieve regional network management, facilitating overall supervision and real-time monitoring. However, this patent requires the installation of a large number of optical fibers, which is very inconvenient to implement. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a natural gas pipeline safety monitoring and alarm system, comprising an alarm module, a monitoring module, a wireless transmission module, and a cloud server. The alarm module is used to acquire gas data and detect gas pipeline leaks. The monitoring module is used to acquire the device status information of the alarm module and the gas detection data acquired by the alarm module, and to monitor the alarm module. The monitoring module sends the data to the wireless transmission module, which transmits the data to the cloud server via a wireless network. The cloud server then parses the data to analyze the detection data of the natural gas pipeline.

[0005] Further steps for inspecting natural gas pipelines include:

[0006] Step S101: The monitoring module periodically acquires the status information of the sensor module, including whether the sensor is online, sensor readings, alarm information, and fault information.

[0007] In step S102, the monitoring module formats the sensor information and transmits it to the cloud server via the wireless transmission module, where the cloud server parses the data.

[0008] In step S103, the content parsed by the cloud server can be viewed through monitoring devices, and the person in charge can also be notified via SMS or voice call.

[0009] Furthermore, the data is formatted in JSON format, and the data fields included in the JSON include the sensor's device number, installation time, device status information, device maintenance information, and remarks information.

[0010] Furthermore, the cloud server stores sensor-related information, including sensor brand, model, specifications, and installation drawings. The relevant information in the cloud server can be retrieved by the sensor's device number.

[0011] Furthermore, the monitoring equipment includes computer devices, large-screen monitors, and mobile devices. The computer devices and large-screen monitors view the monitoring information of the sensor devices through the data display on the front-end website. The mobile devices can view the information by requesting the interface services of the cloud server. The interface services of the cloud server include front-end website display, APP services, and mini-programs.

[0012] Furthermore, the steps of parsing and monitoring data through cloud servers include:

[0013] Step S201: Parse the formatted data content and obtain the device status flag bit;

[0014] Step S202: Determine the device status flag. If the device status flag indicates a fault-free online state, parse other information about the device normally. If the device status indicates a faulty online state, further parse the fault information in the data content. If the device status flag indicates an offline state, notify the device manager through a pre-set notification method.

[0015] Step S203: When the processed device data information changes, update the device status flag.

[0016] Furthermore, the monitoring module periodically uploads sensor information data, the cloud server records the most recent upload time, sets a device offline time threshold, and issues an alarm notification when the time threshold is exceeded.

[0017] Furthermore, the cloud server is equipped with open interfaces that allow it to connect with other platforms.

[0018] The beneficial effects of this invention compared with the prior art are: (1) This invention monitors the data of the sensor module in real time through the monitoring module to realize remote monitoring; (2) This invention connects the data to the cloud server through the wireless transmission module to ensure that the alarm information can be notified as soon as possible, so that the safety manager can receive the alarm information in time, and then conduct investigations to solve potential safety hazards.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 The natural gas pipeline safety monitoring and alarm system shown includes an alarm module 1, a monitoring module 2, a wireless transmission module 3, and a cloud server 4. The alarm module 1 is used to acquire gas data and detect gas pipeline leaks. The monitoring module 2 is used to acquire the device status information of the alarm module 1 and the gas detection data acquired by the alarm module 1, and to monitor the alarm module 1. The monitoring module 2 sends the data to the wireless transmission module 3, which transmits the data to the cloud server 4 via a wireless network. The cloud server 4 then parses the data to analyze the detection data of the natural gas pipeline.

[0025] The alarm module 1 and the monitoring module 2 are electrically connected and communicate via the RS485 protocol.

[0026] In this embodiment, the steps for inspecting the natural gas pipeline include:

[0027] Step S101: The monitoring module 2 periodically acquires the status information of the sensor module, including whether the sensor is online, sensor readings, alarm information, and fault information.

[0028] In step S102, the monitoring module 2 formats the sensor information and transmits it to the cloud server 4 via the wireless transmission module 3, where the cloud server 4 parses the data.

[0029] In step S103, the content parsed by the cloud server 4 can be viewed through monitoring devices, and can also be notified to the person in charge via SMS or voice call. The communication method of the security person in charge can be set through the cloud server.

[0030] The data is formatted as JSON. The JSON data fields include the sensor's device number, installation time, device status information, device maintenance information, and remarks. The device maintenance information records the device's repair time and fault status. The remarks field can add detailed information about device maintenance and other remarks about the device.

[0031] The cloud server 4 stores relevant information about the sensors, including sensor brand, model, specifications, and installation drawings. This information is stored in a database. By using the device number as the primary key, the relevant information about the device can be searched in the cloud server 4, thereby associating it with the data uploaded by the wireless transmission module.

[0032] The monitoring equipment includes a computer device 401, a large screen monitor 402, and a mobile device 403. The computer device 401 and the large screen monitor 402 can view the monitoring information of the sensor device on the large screen through the data display of the front-end website. The mobile device 403 can view the information by requesting the interface service of the cloud server 4. The interface service of the cloud server 4 includes front-end website display, APP service, and mini-program.

[0033] The steps for parsing and monitoring data via cloud server 4 include:

[0034] Step S201: Parse the formatted data content and obtain the device status flag bit;

[0035] Step S202: Determine the device status flag. If the device status flag indicates a fault-free online state, parse other information about the device normally. If the device status indicates a faulty online state, further parse the fault information in the data content. If the device status flag indicates an offline state, notify the device manager through a pre-set notification method.

[0036] Step S203: When the processed device data information changes, update the device status flag.

[0037] Monitoring module 2 periodically uploads sensor information data, and cloud server 4 records the most recent upload time and sets an offline time threshold for the device. When the time threshold is exceeded, an alarm notification is issued.

[0038] Cloud server 4 has open interfaces that allow it to connect with other platforms. Data available to other platforms can be obtained by sending HTTP POST requests to cloud server 4's interfaces.
