Rope Winch Infinite Control Communication System
■System overview
The system is mainly composed of mine wireless network switch, red light warning alarm signal indicator, mine explosion-proof display, wireless transmitter (position sensor), mine intrinsically safe wireless camera, mine explosion-proof and Intrinsically Safe Power Supply, etc. The main equipment composition.
When the winch is running, the front and rear environmental images are captured by the towing shuttle car and the camera is installed along the way. The image signal is transmitted through the transmitter. The wireless network switch installed along the way receives the signal and forwards the signal to the explosion-proof display. The winch driver can observe the front and rear images of the mine car through the explosion-proof display. , Master the roadway environment and operate the winch. Red warning warning and signal buttons are installed along the roadway, and the driver can manipulate the warning signal to remind pedestrians to avoid or stop in time to avoid accidents when abnormal conditions occur during the operation of the winch.
■Main Features
1) "Intrinsically safe operation console for auxiliary transportation" and "Explosion-proof and intrinsically safe programmable control box for auxiliary transportation" have "coal mine safety mark certificate".
2) The core control part adopts German Siemens PLC system, isolation safety barrier and other high-quality devices, the system is stable and reliable, and has strong resistance.
3) It has the function of lever-type stepless speed regulation and intelligent drawing of shuttle trajectory (section diagram of installation roadway) and real-time simulation and display of shuttle running condition (whether it is in a variable grade point, a flat road, a curve or a fork, etc.) , It is convenient for the driver to control the increase and decrease in time according to road conditions.
4) With an Ethernet data upload interface, it is convenient for the dispatching room to centrally monitor the operation of multiple sets of infinite rope systems underground (such as equipment operating status, operating parameters, etc.).
5) It has operating information display functions such as system operating status, operating speed, shuttle position (relative percentage of stroke), traction current, motor speed, and accumulated operating time.
6) It has the functions of overspeed, nose offside, tail offside, emergency stop along the line, emergency stop with leakage, switch reluctance controller failure, and fault memory query.
7) It has acousto-optic warning function for key points along the line (sloping points, bends or forks, etc.). In the case of a communication acousto-optic annunciator (one installed every 100 meters along the line) and a leaky communication system, the system is The dual-signal system can realize functions such as management, call and emergency stop.
8) The programmable control box adopts a sliding door structure and is placed near the operating table (distance ≤ 5 meters), which is convenient for system maintenance and has good system scalability, which is convenient for users to upgrade their functions later.
9) All peripheral sensors (such as speed sensors, shaft encoders, pressure transmitters, travel switches, etc.), consoles and programmable control boxes have been certified by the National Testing Center for system intrinsic safety
10) The system has an energy braking feedback function, and the endless rope transportation system is more energy-saving, efficient and safe.
