[0019] The foregoing and hereinafter detailed description of the invention becomes clearer when read in conjunction with the following drawings, in which: Figure 1 This is a system composition diagram of the present invention; Figure 2 This is a diagram showing the composition of the protocol conversion module of the present invention; Figure 3 This is a flowchart of the protocol conversion module of the present invention. Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions of this invention, several specific embodiments will be used to further illustrate the technical solutions for achieving the objectives of this invention. It should be noted that the technical solutions claimed by this invention include, but are not limited to, the following embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort should fall within the scope of protection of this invention.

[0021] Example 1 The inconsistent installation times and varying manufacturers and models of video security cameras at the natural gas production site have resulted in incompatibility among many devices, forcing them to operate independently. Some digital cameras are connected to hard disk recorders (DVRs). These signals are routed through a specific channel selected by the DVR and then fed into a protocol conversion module. This module's digital camera protocol conversion service parses the signals for video display. Cameras not connected to DVRs are directly connected to the protocol conversion module, which parses their respective video protocols and converts them into a system-wide standard protocol before display. Audio acquisition at the production site follows the same method as video acquisition. Video camera control and voice intercom are initiated via a request from the front-end interface. Upon receiving the request from the corresponding device, the system uses the protocol conversion service module to convert the common protocol into a protocol that the device can recognize, thus enabling control and intercom functions.

[0022] Furthermore, the access control systems currently used at each well site are independent devices that cannot be connected to the video platform. These systems consist of a door station and a main unit. The intelligent security monitoring system for natural gas production sites of this invention uses access control system account and password information, and registers and sets relevant callback protocols at the backend monitoring center via the SDK protocol. When a call request is initiated on-site, the corresponding door station information is obtained through the callback protocol. The obtained information is then transmitted to the protocol conversion module, and the access control system protocol conversion service in this module parses the data. The backend notifies the frontend service via the WebSocket protocol. Upon receiving the notification, the frontend displays a video window and on-site audio. Clicking "Initiate Request" on the frontend page wakes up the microphone at the backend monitoring center to acquire sound. The collected sound data is packetized and stored on the backend monitoring center server via the WebSocket protocol. The backend service then parses the data through the access control system protocol conversion service in the protocol conversion module and pushes the packetized audio files to the door station in real time, enabling remote calling and door opening functions.

[0023] Furthermore, a large number of analog cameras exist at natural gas production sites, many of which were installed a long time ago. Currently, these analog cameras at well sites capture and save images periodically through the central station's data monitoring configuration software, making integration into a video surveillance system impossible. The intelligent security monitoring system for natural gas production sites of this invention solves this problem. Most of the video from the analog cameras is connected to a hard disk recorder (HDD). By configuring the HDD's video channels, resolution, frame rate, and other parameters, when the system receives a timed image capture task, it retrieves the SDKs (Software Development Kits) from different manufacturers based on the pre-defined camera information. The system application obtains the corresponding site's IP address, port number, username, and password, and then establishes a connection with the on-site cameras through the analog camera protocol conversion service module. Once the system receives the compressed video stream, it decodes it through the protocol conversion service module, obtaining a continuous frame sequence. A frame is then extracted according to the system's original definition, saved as an image, and subsequently written to a file specified by the system for display.

[0024] An embodiment of the present invention discloses an intelligent security monitoring system for natural gas production sites. The system includes front-end monitoring equipment and a back-end monitoring center.

[0047] Example 2 This embodiment discloses an intelligent security monitoring system for natural gas production sites. Based on embodiment 1, when it is necessary to conduct voice communication with a production site under the backend monitoring center, the system first selects any camera in the site at the backend monitoring center and turns on voice communication.

If there is no threat, it indicates a false alarm from the camera, and the alarm is filtered out. After the final alarm information is generated, an alarm prompt will also pop up on the monitoring screen in the system's backend monitoring center.

[0050] It is understood that the camera alarm module in the backend monitoring center is connected to the video surveillance control module and the hard disk recorder control module, respectively, and performs data transmission and exchange. The cameras within the site first transmit the collected data to the protocol conversion module via a wired network and / or wireless network. After the data information protocol is converted, the data is transmitted to the video surveillance control module and the hard disk recorder control module. Then, the camera alarm module receives the data information transmitted from these two modules and performs the above-mentioned alarm signal judgment. When a camera alarm signal exists, the corresponding alarm image is transmitted to the intelligent recognition module for intrusion risk judgment.
