What are the ideas and practical significance of informatization construction?

Thinking and Practice of Informatization Construction

(1) Industrial video control ring network, industrial automation control ring network and dual redundant 10 Gigabit information ring network have been built, which provides effective guarantee for stable data transmission.

The mine has built an independent industrial control 10 Gigabit ring network, and the industrial control network is separated from the visual video network to realize the private network.

The industrial control network and the visual video network are physically isolated from the information network through network security equipment such as industrial gates and firewalls, thus effectively ensuring network security; Upgrade the information network core, access the network, and realize the 10 Gigabit link connection with group companies and coal companies.

(two) the construction of mine comprehensive automation platform, to achieve multi-system remote monitoring, fixed workplace unattended, reducing personnel efficiency.

At present, the integrated automation platform is connected with 13 industrial subsystem and 123 large-scale mechanical equipment, including six systems of pumping, pressure, pumping, exhaust, supply and main transportation machinery, three systems of gas pumping and exhaust, oxygen making device, centralized control of local ventilator and overhead passenger device.

The subsystems of No.3 mining area have realized unattended and remote monitoring, and emergency linkage has been realized among multiple systems.

(3) Build a comprehensive mine information platform to realize multi-system integration, and take the information island as the existing "* * * sharing platform" to form dynamic management and closed-loop monitoring.

The information platform includes "one map" management and application of mine hologram, intelligent retrieval and analysis, business collaborative management, structural map editing, report system, 3D GIS display system, big data analysis system, management module and theme analysis.

The platform integrates safety monitoring, personnel position monitoring, communication scheduling, emergency broadcasting, mine pressure monitoring, hydrological monitoring, fire monitoring, industrial video and other systems to realize real-time monitoring and monitoring of mines and realize multi-systems.

(d) Safe production of visual video system, strengthening the horizontal management length and vertical depth.

The visualization system has more than 2,000 cameras, covering underground production areas and important fixed factories, realizing remote monitoring and unattended operation.

Through the video, we can know the real-time situation of the underground site remotely and correct the irregular behavior of employees. "Electronic police" has changed "crowd tactics", reduced management intensity and improved management effect.

In-depth use of camera AI's intelligent identification function, with the intelligent identification of typical violations such as mechanical transportation, mining and drilling rigs in colleges and universities. , to warn the workers who do not wear helmets, invade the cordon, and violate the operating rules in the maintenance of mechanical equipment.

Three, adhere to the bright spot of mine intelligent construction (1) planning and guidance, and build the standard system of mine information construction.

Through the mine informatization construction, the standards of GIS platform and map application, comprehensive automation platform construction and information integration platform construction in each mining area of the company were established, and the standard system of coal company informatization construction was formed, which provided a unified standard for other mines to promote the intelligent construction of coal mines in an orderly manner.

1. Effectively and stably connect, integrate and exchange information system construction and public basic information platforms such as master data platform, integrated portal platform and integrated authentication platform, and realize the integration of user management, integrated portal management, integrated authentication management, integrated service bus and integrated mobile portal, so as to ensure that each system meets the requirements of architecture, cluster deployment, data storage, system access and system authority.

2.2 application standards. GIS platform and map.

In order to standardize the drawing standards of various mines, build an open, inclusive and unified GIS platform and the application of mine unit maps, standardize the drawing standards of various mines, realize the call and integration of GIS unit maps of different manufacturers by a unified platform, and break the convention that a single manufacturer monopolizes GIS systems.

This standard regulates the layers and legends of various drawings such as land survey, waterproofing, production technology, three defenses, electromechanical transportation and monitoring, including drawing contents, visual styles, symbol elements, layer requirements, coordinate system, etc.

Clarify the data exchange mode, scope, frequency and security mechanism, unify the name, function and parameters of API interface, and meet the requirements of GIS map calling and data superposition of the group, coal company, mine production three-level platform and application system.

(2) Building a data center and standardizing all kinds of data storage provide an effective guarantee for long-term effective data call.

Data centers include most database clusters and data warehouses.

Among them, the database cluster is deployed on the mine virtual server, and the data warehouse where all the data of mine professional subsystems are stored is centrally deployed on the cloud platform of the group company for data analysis, processing, APP application and storage.

1. Hardware platform.

Production mines use hyper-converged servers to build integrated automation data centers and information data centers, which are connected to industrial control networks and information data centers are connected to information networks.

2. Software deployment.

Software such as database, data exchange tool, data service bus, data report and analysis tool are deployed in a way of "physical concentration and logical separation" to complete data collection, cleaning, conversion and storage, and realize data interaction and sharing among the three data centers.

Production system and real-time data are deployed in the mine data center, while non-production system and real-time data are centrally deployed in the data center of the group company, including portal, data warehouse and BI data display.

3. Data management.

The integrated automation platform for production mines collects data from all automation subsystems, cleans up and converts the collected data, and saves it in the SCADA historical real-time database of the data center. The data interface of the group company is unified and standardized, and the data of the business subsystem and the SCADA historical real-time database of the integrated automation platform are collected according to the requirements of the agreement. Through cleaning and transformation, standard data are stored in the data warehouse of information integration platform, which comes from different systems and different formats.

The data center of the company collects the business subsystem data and data warehouse data of the mine comprehensive information platform, and forms standard data through cleaning and conversion, which is stored in the data warehouse of the comprehensive information platform for important data such as mine information, geographical location information and equipment information.

(3) Insist on effective guidance to form a new road of information construction in mining areas.

The geological conditions in the mining area are complex, and there are five disasters: gas, water, fire, ground temperature and ground pressure. The existing coal mine intelligent equipment and technology are difficult to adapt to the complex geological conditions on site, which brings many problems and difficulties to the construction of intelligent coal mines.

Through long-term practice and exploration, Guqiao Mine has determined the idea of information construction suitable for the characteristics of the mining area, and formed an intelligent mine system covering four levels: "automation and terminal mechanization system integrated intelligent management informationization".

1. Realize the mechanization of "receiving, digging, opening, repairing and digging" wharf.

Mainly to improve the five key technologies of "digging, repairing and drilling". On the basis of the existing mechanization level, the full mechanized coverage will be gradually realized, including mechanized manual coal replacement, rock roadway excavation and charging, hole sealing and anchor cable fixation.

2. Fully automate the "Top Ten Systems".

Six electromechanical systems (pumping, compression, pumping, exhaust, main transportation, power supply (deflation, nitrogen injection, centralized management of local electric fans) and 10 auxiliary transportation systems are automated according to specialties and sections, realizing system integration and linkage.

3. Based on the automation of the wharf mechanization system, the comprehensive intelligent control is realized.

Remote operation, video linkage, one-button stop.

4. Through the automatic collection, standardized processing and comprehensive integration of information such as "terminal mechanization system automation and comprehensive intelligence", combined with the information application of management processes such as safety production and party-mass management, the construction of smart mines will be realized.

Realize automatic data collection, standardized management, interconnection and statistical analysis of all links, provide comprehensive information and data support for managers and operators, improve production and management efficiency, and reduce operation and labor costs.

(4) Multi-system integration and linkage to ensure mine safety production.

By studying the business processes, operation processes and control instructions among multiple systems, the data fusion and linkage of more than 40 automation systems and more than a dozen business systems in the mine are realized.

Comprehensive safety monitoring, staffing, integrated automation, communication video and other industrial real-time data, to build a mine "mining, drilling, machinery, transportation, communication" professional simulation system, to achieve the whole mine "monitoring, management, control" integration.

4. The gap between the intelligent mine construction in Guqiao Mine and the national standard is 1. Intelligent tunneling system: the tunneling equipment does not have automatic cutting function for the time being, and remote cutting and walking are not realized. Tunneling, anchoring, transportation and other equipment do not have complete single-state monitoring and fault self-diagnosis functions, and signal exchange and interlocking between equipment.

2. Intelligent ventilation system: the intelligent perception and analysis of air volume, wind resistance, wind pressure and other parameters of main ventilation pipes are not realized, and the ventilation pipes are intelligently optimized; The fan can't automatically adjust the speed according to the air volume and gas conditions, so it can't save electricity. The main fan can't automatically adjust the frequency according to the production team, and the local fans can't realize on-line frequency conversion.

3. The decision support platform based on cloud computing is proposed for the integrated management platform under the information infrastructure, but 60% of the decision support is not developed, deployed and applied on the platform, and there are no intelligent warehouse systems, intelligent three-dimensional warehouses and unmanned distribution robots.

Suggestion: Reduce the intelligence standard appropriately.

Problems and difficulties in verbs (abbreviation of verb) 1. In the process of intelligent mine construction, it is found that some centralized management subsystems are in the early stage of mine construction, which takes a long time, some electromechanical subsystems are aging, and the software and hardware of each subsystem need to be upgraded urgently.

2. The construction of intelligent mines takes a long time, the task is heavy, and the technical personnel are insufficient. The personnel involved in the construction of intelligent mines lack the professional knowledge reserve of intelligent mine construction, so it is necessary to organize more intelligent mine construction training.
