Functions Achieved

1Dispatching Function

2Interlocking Function

3Display Function

4Management Function

5Unmanned Operation Function

The management computer can automatically print relevant management data or charts.

Management data mainly includes: operational status of electric locomotives and various equipment within the system

Management charts mainly include:

a. Locomotive operation cycle charts; b. System operation logs and related reports, etc.

The computer can reflect the working status of equipment within the system at any time and diagnose fault locations, i.e., it has fault diagnosis functionality.

Train Positioning Function: Train positions are detected using track axle counters, with clear zone boundaries, enabling real-time detection of current position, direction, and speed.

Train Information Identification Function: The system identifies train numbers and types based on information from vehicle identification cards received by card reader substations installed at designated locations.

Train Passing Lockout Function: The system uses track axle counters linked to remotely controlled switches to detect train movements and prevent unauthorized operation. When a train passes a switch, the computer can lock the switch position, rendering local, remote, and driver controls ineffective until unlocked by the computer, ensuring operational safety.safety.

Statistical Function: The system detects train passages via track axle counters at statistical points, counting total cars and trains per shift, current train and car numbers, and generating reports.

Hierarchical Permission Function: Personnel at different levels perform relevant tasks using encrypted keys based on operational needs.

Personnel Management Function: The system connects control substations to card reader substations to read personnel identification card information, enabling personnel management.

Replay Function: Based on recorded operational data, the management computer can replay actual transportation processes at adjustable speeds on display devices, providing basis for accident analysis and調(diào)度 strategy improvement. The system automatically stores transportation data, with historical data retained for one year.

The management computer can print relevant management data, such as: train numbers, times, and locations of red light violations; statistics on material and personnel transport per shift and daily.

Fault Self-Diagnosis Function

It can display the working status of system equipment on monitors at any time, automatically diagnose fault types and locations, and issue prominent alarms.

Visual Monitoring Function: Real-time display of train positions, numbers, directions, car counts, signal status, switch positions, and zone occupancy on computer terminals and graphic devices via text, diagrams, and tables. Real-time display of locomotive status in transportation tunnels, operation history. Operators can oversee the entire system, know each vehicle's precise location, facilitating overall control.

Networking Function: The system is highly scalable, meeting the needs of all coal mining enterprises in China.

The system uses industrial Ethernet to accommodate underground transportation networks of various scales and can integrate into existing bus systems to reduce costs. It can connect via networking communication software to share data with enterprise management systems, achieving integrated management functionality.

The main control system has reserved data interfaces for mine dispatch systems to integrate into mine information systems, allowing remote browsing and diagnosis of system operational status based on authorization.
