Coal mine underground rail transportation monitoring information centralized closed electric locomotive dispatching management system

  Shandong Meian mining equipment supply mine rail transportation monitoring, signal centralized closing, locomotive dispatching management system, pneumatic and electric driver controlled turnout device, locomotive section locking device and locomotive signal indication system

The system is a wireless network + Fieldbus Industrial Control System for harsh environment
Based on the transportation monitoring system, the system realizes monitoring and automatic dispatching of mine car transportation in the ground main control room
It can display the train position, train number, signal lamp, turnout status and section occupation of underground roadway in real time, and command the safe operation of the train
The system can reflect the working status of equipment and sensors in each section at any time, automatically diagnose and alarm faults, record operation process data, and generate management report and train cycle diagram; The whole system has no moving contact and adopts electrical isolation with high reliability; The software and hardware of the system have been upgraded for many times
The man-machine interface of the operating system based on windows is very friendly and easy to operate, which makes the interlocking and management function of the system more powerful
The system design follows the industrial standards such as coal mine safety code, technical equipment standard of underground locomotive transportation signal system, code for design of underground locomotive transportation signal in coal mine, and is technically safe and reliable
The system is mainly composed of main control equipment, communication station, control substation, Jie receiver, transmitter, driver controlled electric turnout device, system display (signal lamp), language alarm device, vehicle sensor and other equipment

Realize function
1
Dispatching function
2 locking function
3 display function
4 management function
The management computer can automatically print relevant management data or charts

The management data mainly includes: the operation of electric locomotive and various equipment in the system
Management charts mainly include:
a
Locomotive operation cycle chart; b
System operation log and related reports, etc

The computer can reflect the working state of the equipment in the system at any time and diagnose the fault location, that is, it has the function of fault diagnosis

Train positioning function: the train position is detected by track axle counter sensor, the section division boundary is clear, and the train positioning information such as the current position, running direction and speed of the train are detected in real time

Train information identification function: the system identifies the train number and vehicle type according to the information of the vehicle identification card at the head of the train received by the card reading sub station installed at the set position

Passing refusal function: the system has the function of real-time detection of passing refusal by the driver controlled turnout associated track axle counter, that is, when the turnout passes, the computer can send a signal to lock the turnout position
After the turnout is locked, the local, remote and driver controls will lose their function until the computer is unlocked, so as to ensure driving safety

Statistical function: the system detects the train passing through the track axle counter installed at the statistical point, can count the total number of vehicles, current trains and vehicles at the statistical point on duty, and can generate a report

Hierarchical authority function: personnel at all levels carry out relevant operations in the system with secret keys according to work needs

Personnel management function: the system control sub station is connected to the card reading sub station to read the personnel identification card information and realize the personnel management function

Replay function: according to the recorded operation process data, the actual transportation process within the time can be reproduced at any speed on the management computer display equipment, so as to provide a basis for analyzing the cause of the accident and improving the dispatching strategy
The system shall automatically store the transportation data, and the historical data can be retained for one year

The management data can be printed on the management computer
For example: the vehicle number, time and place of running the red light; Make statistics on the material and personnel transportation of each shift and every day

Fault self diagnosis function
It can reflect the working state of the equipment in the system at any time on the display, automatically diagnose the fault type and fault location, and send out eye-catching alarm prompt

Adopt fault safety design: if any communication node and any control execution equipment in the system fails, it will automatically conduct safety locking to make the system lead to safety mode, and the annunciator will give special flashing signal to instruct the driver to take corresponding measures

Visual monitoring function: real-time display of operation status information such as train position, train number, operation direction, number of cars, status of annunciator, turnout position and section lock in the form of text, simulation diagram and table on computer terminal and graphic equipment
Real time display of the running locomotive status of the transportation roadway, which has run
The operator can look at the overall situation and know the specific location of each vehicle for overall control

Networking function: the system has large scalability and can meet all domestic coal mining enterprises

The system adopts industrial Ethernet to meet the needs of underground transportation network in coal mines of different scales, and can also be connected to the existing bus system, so as to reduce the cost
The system can access the LAN through the network communication software, share data with the internal management system of the enterprise, and achieve the function of management integration

The main control system reserves a data interface with the mine dispatching system to integrate into the mine information system, and can remotely browse and diagnose the operation status of the system according to the authorization

Other functions
Compatibility and expansibility: the system has good compatibility and expansibility
Remote diagnosis and maintenance function: the remote computer can diagnose and maintain the system through the network without affecting the operation of the system

Standby power supply function: in case of system power failure, the regulated power supply can provide backup power supply for more than two hours

Alarm function: including communication fault alarm and train red rush
