Key words: colliery EIP surveillance configuration 【Background】 The energy industry is the lifeline of our country's economic development. In recent years, with the shortage of oil resources and the soaring oil prices, the importance and irreplaceability of the coal industry have become increasingly prominent. However, the safety production situation of China's coal industry is not optimistic, especially with frequent reports of serious and major accidents. According to incomplete statistics, in 2003, China's coal production accounted for 35% of the world's production, but the number of accidents and casualties accounted for 80%. Among these accidents, gas explosions accounted for the vast majority. While many factors contribute to the frequent accidents, incomplete safety monitoring and outdated management methods in various coal mining enterprises are also significant reasons. With the increasing emphasis placed on coal mine safety by the state and the growing need for modern management within mining bureaus, coal mine safety monitoring systems are becoming increasingly crucial. From both technical and managerial perspectives, networked safety monitoring of coal mine systems is an inevitable trend. As a leading hardware supplier in the control and automation industry, Advantech Intelligent Technology Co., Ltd. possesses successful experience and mature case studies in safety monitoring systems. Using configuration software as an example, this paper analyzes the safety production monitoring system of XX Mining (Group) Company as a case study. 【System Requirements】 The safety production monitoring system currently used by XX Mining (Group) Company is a real-time monitoring system for production, safety, and management, playing a vital role in assessing the coal mine's production operation status, safety level, and disaster prediction and forecasting. To strengthen the group company's safety production management over its subordinate mines and to utilize existing network resources to monitor the safety and production status of each mine, a safety production monitoring information system was established. This system integrates real-time monitoring data from each subordinate mine into the company's dispatch center, forming a company-level safety production monitoring network. Each subordinate mine, in turn, integrates its own production and safety data into its own dispatch center, creating a mine-level monitoring subnet. This allows all departments and leaders within the company to monitor the production and safety status of each mine at any time, enabling comprehensive dynamic analysis and providing a basis for leadership decision-making, thus achieving resource sharing. The coal mine safety production monitoring system is a real-time dispatch and command system. Through this system, management can quickly, timely, and accurately obtain production-related data, improving the scientific nature of decision-making and thereby avoiding or reducing safety accidents and economic losses caused by decision-making errors. This system transmits remote monitoring information from each mine to headquarters via the group company's Ethernet network and can analyze and summarize the monitoring information from each mine, providing decision-making support for leadership. [Current Status of Control Systems] XX Mining (Group) Company has six coal mines requiring network monitoring. Each mine has an independent monitoring system in use, but these are not products from the same manufacturer. Details are as follows: | No. | Manufacturer | Model | Quantity | Remarks | |---|---|---|---|---| | 1 | ×× Automation Research Institute | KJ95 | 3 | All mines are networked, including three mines | | 2 | ×× Coal Mine Safety Instrument General Factory | KJ75 | 1 | One mine is not yet networked | | 3 | ×××× Research Institute | KJ90 | 1 | One mine is not yet networked | | 4 | Honeywell (USA) | HIMASS | 1 | One mine is not yet networked | As can be seen from the above, many companies are involved in the coal mine safety monitoring industry in my country. However, there has never been a unified communication protocol for coal mine safety monitoring systems. The systems are in a closed state, unable to share information, making it difficult to achieve global or higher-level networking for real-time monitoring and management. Almost every system has its own protocol standard, and even different versions of products from the same manufacturer may have inconsistent protocols. Therefore, achieving system networking is extremely difficult. The systems used in different mines within a mining bureau are often different, typically involving multiple safety monitoring systems. From our understanding, the openness of these systems also varies; some can store data in relational databases, while others have their own data systems. Even among relational databases, some only store historical data, while others store real-time data simultaneously. Some manufacturers even encrypt their databases to ensure system confidentiality. Therefore, networking all systems requires sufficient technical capabilities for data decryption. With increasingly stringent requirements for coal mine safety, networking of various coal mine systems is essential. Regardless of the manufacturer, the equipment and systems technically support networking and data exchange, providing third-party data interfaces or standard communication protocols such as OPC and DDE. This means that using configuration software to collect data from various systems for networking and configuration is entirely feasible. 【System Construction Plan】 This system implementation is divided into three parts: developing data acquisition interfaces for existing control systems, building a real-time database, and user configuration. The system network diagram and data flow diagram are shown below: Developing data acquisition interfaces for existing control systems is a key technical challenge in the entire system construction. Some early control and monitoring systems in coal mines, due to technological limitations at the time, did not provide external data interfaces, making connection difficult and generally requiring contact with the original manufacturer for solutions. Control systems implemented in the 1990s typically have various external data interfaces. Utilizing the rich external data interface protocols, methods, and standards provided by industrial control configuration software, the development of data acquisition interfaces for existing control systems can be completed, thereby achieving network connectivity for the entire system. After establishing communication with the existing control system, a real-time database and user engineering configuration are built according to the requirements of the entire coal mine safety production monitoring system construction, completing the establishment of all required functions of the entire system. 【Main System Product Configuration】 1.

Good security: All design schemes fully consider the security of the system, and the impact of using the acquisition system on the monitoring system is minimized. The method of setting up a data acquisition computer isolates the local area network (LAN) from the control network, thereby avoiding the impact of human factors or computer viruses on the monitoring system within the LAN; 3. Fast response speed: the client access speed to the real-time database is less than 1 second; 4. Stable operation: the real-time data platform has undergone rigorous testing and long-term operation and has good stability; 5. Strong scalability: it provides open I/O interface specifications to enhance system scalability; 【Conclusion】 By combining Advantech industrial control computers with industrial control configuration software, real-time scheduling and monitoring of coal mine safety production can be realized. This not only solves the problem of low overall technical level and backward management in the coal industry and improves the industry's information management level, but more importantly, it can monitor the safety status of each mine in real time, dispatch and command production at any time, and avoid and reduce the occurrence of safety accidents. Therefore, the construction of a coal mine safety production monitoring system is of great significance to the safe, civilized, and scientific production of coal enterprises.
