The intelligent coal conveying system adopts a unified platform software to converge the main coal flow transportation system into an integrated monitoring platform, fully considering the access and integration of subsystems, saving investment, sharing resources, improving system functions, and laying a solid technical foundation for mine construction. Data from each subsystem can be effectively integrated and organically consolidated under heterogeneous conditions, achieving comprehensive management of related business data. Personnel in the centralized control center can monitor and control all equipment in real time through corresponding permissions, realizing the digitization and intellectualization of data collection, production scheduling, and decision-making command for belt conveyors, coal bunkers, coal feeders, etc., achieving the goal of safe and stable main coal flow transportation system and efficient coal mine production.
On the basis of fully grasping the operating parameters and information of the coal flow transportation system equipment in the centralized control center, the intelligent operation of the coal flow transportation system, on-site unmanned operation, and few-person inspection mode are realized.
Integrating video analysis, industrial control and other systems, utilizing intelligent video analysis equipment and PLC control equipment, and forming an intelligent, multi-functional, all-weather dynamic safety intelligent power-saving system through belt frequency converters, achieving the combination of intelligent video and industrial control, realizing intelligent control of automatic speed regulation of transportation belts, and achieving the goal of power saving.
Linked with video, when a fault occurs or equipment starts, video images are automatically popped up to visually display equipment status.
Through the motor preventive maintenance system, real-time monitoring of motor vibration frequency and temperature is carried out, and the motor operating status is predicted in real time.
Equipped with environmental monitoring and early warning functions for the main coal flow transportation system, realizing intelligent monitoring of smoke, dust, temperature, etc.
The transportation control system is complete with full protection.
Strengthen the monitoring and scheduling of unmanned transportation, and improve auxiliary transportation capacity.
Transmit production and safety information anytime and anywhere, providing first-hand data for production command.
Improve operational quality and efficiency, reduce costs, and reduce direct production personnel.
Ensure the shared integration and comprehensive utilization of various information resources and hardware resources, avoid information islands, reduce information redundancy, and facilitate maintenance.
The construction of intelligent platform software is a core content of the intelligent coal conveying system. The software is built using a B/S technical architecture. On this platform, through the human-machine interface, the working conditions of subsystem equipment can be monitored in real time, and the I/O of each subsystem can be monitored and controlled. At the same time, through stored historical data, the equipment conditions of each subsystem can be analyzed, queried, and statistically analyzed. Corresponding expandable space is reserved; it facilitates the access of subsequent subsystems, facilitates system upgrades, facilitates user function expansion, and facilitates secondary development with other platform application systems.
High Availability and Redundancy Functions
Two sets of upper computers (mutually redundant) are set up in the centralized control center. Data synchronization between the two upper computers is automatically realized, and they serve as hot backups for each other. When one server fails, the other automatically takes over to prevent data loss.
Operation Interface
The interface is friendly. The human-machine interface can display information of each monitoring point underground, displayed in real time in forms such as data, curves, and messages, and can perform multi-screen switching.
Monitoring Functions
It can collect data from each subsystem in real time and accurately. On any operation station, operators of each specialty have their own permissions, can monitor the operating conditions of automation system equipment according to different permissions, and can control on-site equipment as required.
Control Functions
It has multiple functions such as remote single start/single stop, automatic start/automatic stop, emergency stop, and reset, realizing remote start-stop of the main transportation system in the direction of coal flow or against the direction of coal flow.
Report and Curve Functions
The system provides real-time and historical report curves. The real-time curve screen reflects the change trend of real-time data over a certain time interval. The historical curve screen reflects the change trend of real-time data over a past period of time. Through curve reports, the parameters of each main equipment of the subsystem are continuously recorded and saved for future query and call management.
Printing Functions
It can print the operating parameters and operating status of related equipment of each subsystem in real time or by time period, such as start-stop status, fault messages, fault occurrence time, etc.
Historical Event Recording Functions
In chronological order, the historical actions of each device are recorded for post-event analysis.
Real-time Alarm Functions
When equipment fails or analog quantities exceed limits, the monitoring subsystem and the automation platform synchronously display the faulty equipment name, location, occurrence time, and fault message, and can provide video images, voice alarm prompts, and print output.
Accident Recall Functions
It can recall equipment fault reports and equipment operating conditions.
Fault Self-diagnosis Functions
It has powerful system self-diagnosis and fault alarm functions, and can accurately determine the type and location of equipment faults.
