Centralized Control Work Surface System
■System overview
Working face Centralized Control System can realize the protection of coal mining face, control, call along the line, fault detection, display and alarm functions. The real-time monitoring data of the working face centralized control system can be transmitted to the comprehensive automation network control platform of the mine in real time, and text, graphic display, production system operation and fault status can be realized on the ground dispatching smart digital terminal, and the working face related integrated equipment in the ground dispatching hall Perform remote control.At present, under the static picture, the video splicing picture effect of the work surface is stable. In the next step, the key point of the technical staff is to adjust the screen splicing under the dynamic state of the working face, and finally realize the purpose of remotely guiding production.
■Main feature
1. The system can realize remote access and remote diagnosis; for example, the historical database of the electro-hydraulic control system host in the face automation system integration can be directly accessed through FTP, which saves the software cost of rebuilding the historical database in the ground room. At the same time, in the dispatching room, you can remotely log in to the working face electro-hydraulic control system host, thus becoming a virtual terminal of the working face host, realizing the control of the working face electro-hydraulic system host. The integrated PLC can also be remotely programmed and diagnosed in the ground dispatching room.
2. Optical fiber communication is used between the belt head and the working surface. It has the advantages of wide bandwidth, large communication capacity, low loss, anti-electromagnetic interference, and no charge. It is very suitable for flammable, explosive and other dangerous environments.
3. The network speed is fast, up to Gigabit or even more, and the real-time data is very high, which provides sufficient conditions for remote monitoring.
4. Support redundant connection configuration, strong data reachability, data has multiple channels to reach the destination;
5. It is easy to seamlessly connect with the enterprise information network. Through the information publishing function of the WEB network, the information network can obtain the same access and operation authority as the industrial network in the case of system voting.
