[0029] Terminology Explanation:
[0030] DCS stands for Distributed Control System.
[0031] SCADA stands for Supervisory Control and Data Acquisition.
[0032] A digital collaboration platform is a comprehensive collaborative system that integrates digital technologies (such as big data, cloud computing, and the Internet of Things) with intelligent capabilities (such as artificial intelligence and process automation).
[0033] This embodiment provides a smart gas station safety dynamic monitoring system, such as... Figure 1 As shown, it includes: a high-point monitoring unit, a low-point monitoring unit, and an industrial control unit; the high-point monitoring unit, the low-point monitoring unit, and the industrial control unit are respectively connected to a PoE switch, the PoE switch is connected to a core switch, and the core switch is also connected to a storage server and a digital collaboration platform.
[0034] In a specific implementation, the high-point monitoring unit includes an explosion-proof panoramic monitoring camera deployed on the top of the tank area, covering the entire site with a coverage radius of 200 meters and a resolution of ≥4K. The explosion-proof panoramic camera is connected to a PoE switch via a network cable to transmit high-point panoramic video and data in real time.
[0035] In a specific implementation, the low-point monitoring unit includes a laser methane PTZ camera, a riot gun-type camera, an explosion-proof intelligent dome camera, and an explosion-proof thermal imaging camera.
[0036] The laser methane PTZ camera is deployed around the perimeter of the process area. Its PTZ section allows the device to rotate freely in both horizontal and vertical directions to cover a wider monitoring area. The laser methane PTZ camera is connected to a PoE switch via Ethernet cable to transmit methane concentration data and video images in real time.
[0037] The explosion-proof intelligent dome cameras are deployed in areas such as the top of gas storage tank areas, key nodes of process valve groups, gas loading and unloading areas, and high points along the perimeter of the site. The cameras are connected to a PoE switch via network cable to transmit low-point video and data in real time. They feature automatic tracking and intelligent analysis functions, support 360° rotation and 30x optical zoom for dynamic tracking of detailed video. The 360° rotating pan-tilt unit and zoom lens enable comprehensive monitoring of the curved surfaces of the tank area without blind spots; a built-in dual-spectrum sensor simultaneously acquires visible light video and thermal imaging temperature distribution; and in response to laser methane pan-tilt alarm signals, automatically adjusts to the estimated leak coordinates.
[0038] The bulletproof cameras are deployed at process pipeline flange / valve interfaces, inside pressure regulating cabinets, in liquefied gas cylinder storage rooms, and at station entrances / perimeter low walls. The cameras are connected to a PoE switch via network cable to transmit low-point video and data in real time. They feature remote announcement and strong light illumination functions, and the fixed, precise 65° horizontal field of view covers minute changes in the status of critical equipment. Built-in fog-penetrating filters and infrared supplementary lighting modules enable visualization of leaked gas.
[0039] The explosion-proof thermal imaging camera is deployed above the pump unit and can be used for monitoring at night or in severe weather conditions. It has a temperature measurement range of -20℃ to 550℃ and an accuracy of ±2℃. The explosion-proof thermal imaging camera is connected to a PoE switch via a network cable for equipment overheating early warning and fire prevention.
[0040] In a specific implementation, the industrial control unit includes a DCS, SCADA system, serial port devices, and a serial port server. The serial port devices are connected to the serial port server via an RS232 or RS485 bus. The serial port server is connected to a PoE switch via its built-in network interface. The serial port devices include pressure sensors, flow sensors, combustible gas detectors, and other similar devices.
[0041] Pressure sensors are installed on the outlet pipeline of the pressure regulator and upstream of the emergency shut-off valve of the storage tank to detect the real-time pressure value of the gas pipeline network. The pressure value can be used to predict the risk of seal failure and trigger valve interlock control.
[0042] Flow sensors are installed on the main outlet pipe of the gate station and the branch pipes of industrial and commercial users to detect the flow rate of gas. The flow rate of gas can be used to quantify the scale of leakage and locate abnormal gas usage behavior.
[0043] Combustible gas detectors are installed on the floor of the process area and at the bottom of enclosed spaces to detect the concentration of methane and propane. The concentration of methane and propane can be used to provide early warning of leaks and drive the exhaust system.
[0044] All data detected by serial port devices is converted into Modbus protocol data by the serial port server and output to the PoE switch. The serial port server can convert RS485 / Modbus to TCP / IP protocol and supports concurrent access of 3000 devices.
[0045] The serial port server connects to the industrial control network via Ethernet to exchange data with DCS or SCADA systems. The serial port server converts the Modbus RTU protocol of the serial devices to the Modbus TCP protocol. The DCS control station or SCADA host computer acts as the Modbus TCP master station, reading device data (such as temperature and pressure) forwarded by the serial port server (slave station) through the network, or sending control commands to the devices. The serial port server is responsible for connecting serial device data to the network for joint use by the DCS and SCADA systems.
[0046] In a specific implementation, the PoE switch provides IEEE 802.3bt power supply, with a single port power of ≥90W, and supports deployment in explosion-proof areas.
[0047] In a specific implementation, the PoE switch is connected to the core switch to aggregate power supply and data transmission from explosion-proof monitoring equipment. It encapsulates heterogeneous data such as Modbus / RTSP into unified Ethernet frames and prioritizes the transmission of leakage alarm data through a dynamic QoS mechanism. Multiple PoE switches are deployed, each covering an independent explosion-proof zone. They are connected to the core switch via a 10 Gigabit fiber optic link and provide ≤30W DC power to the explosion-proof monitoring equipment via the IEEE 802.3at protocol. They aggregate multi-protocol data streams such as Modbus / RTSP, perform VLAN priority marking, and respond to traffic scheduling commands from the core switch.
[0048] The core switch is deployed in the control room, supports 10 Gigabit fiber optic interfaces, divides VLANs, and distinguishes between video streams and control commands.
[0049] In a specific implementation, the digital collaboration platform, output server, and storage server are connected to the core switch via network cables.
[0050] The intelligent collaborative platform integrates a data fusion engine, a resource scheduling engine, and an early warning decision engine. The data fusion engine realizes spatiotemporal alignment and feature correlation of multi-source heterogeneous data and outputs a dynamic risk map. The resource scheduling engine dynamically allocates network, computing, and storage resources according to QoS levels to ensure zero interruption of alarm services. The early warning decision engine generates disposal instructions based on the leakage propagation model and the contingency plan library, driving the SCADA system to execute interlocking control.
[0051] The output server is used to provide high-resolution video or image output to enhance the visualization of the monitoring system, and supports parallel analysis of 16 channels of 4K video.
[0052] The storage server employs a distributed storage architecture to store device status data, environmental awareness data, and video data for subsequent review and analysis. It supports the retention of petabyte-level video data for ≥90 days.
[0053] One end of the large screen is connected to the core switch via a network cable, and the other end is connected to the output server via an HDMI cable. The large screen is an LED splicing screen with a resolution of 7680×4320, and supports the overlay display of GIS maps and 3D models.
[0054] Working principle of this utility model:
[0055] This utility model achieves comprehensive collection of video data from different locations through high-point monitoring units and low-point monitoring units, and provides dynamic monitoring of the entire gas station scene. At the same time, the low-point monitoring unit includes a laser methane PTZ camera that can acquire methane concentration data and video data.
[0056] High-level monitoring units deploy explosion-proof surveillance cameras, using ultra-wide-angle lenses to capture global situational video, achieving panoramic monitoring of the tank area and perimeter. Low-level monitoring units deploy explosion-proof gun-type cameras, explosion-proof smart domes, and explosion-proof thermal imaging cameras to achieve detailed equipment monitoring, and deploy laser methane PTZ cameras to simultaneously acquire methane concentration data and leak point video. Industrial control units collect pressure, flow, and valve status data through the DCS / SCADA system, with serial devices outputting Modbus protocol data via a serial server. PoE switches aggregate all received data and transmit it to the core switch. The core switch efficiently forwards the received data to the video storage server, the digital collaboration platform, the output server, and the large screen.
[0057] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
