The system is controlled by a PLC. The network uses fieldbus communication; the communication network runs through shielded multi-pair cables or armored fiber optics, while fail-safe control signals are connected with hard-wired cables;
The system has a number of external interfaces, and can be seamlessly connected with other related devices such as the mine cart operating system;
The system has a power supply voltage of 127V AC, and is equipped with special isolation transformers, offering strong anti-interference capabilities. The primary and control current circuits are wired separately. The entire control system features a compact structure, a variety of functions, stable operation, reliable performance, good adaptability, and good anti-static measures.
Fieldbus communication adopted to reduce wiring;
Low system investment requirements lead to significant economic benefits.
Fast on-site commissioning, easy maintenance;
The system features a novel control method, ensuring simple operation, flexible control and outstanding safety lockout mechanism, conforming to the relevant provisions of Coal Mining Safety Regulations, and can be modified or redefined according to the actual situation on site by field programming;
If the standard signaling system PLC and the shaft cables encounter a failure, operation can be resumed by using the backup signal system. The backup signal system has both visual and audio outputs;
Improves tick number memory, including quantity and other performance statistics;
Each piece of equipment is equipped with a direct telephone;
There are hardwired emergency stop signals between the various pieces of equipment within the system;
Fieldbus communication and hardwired signal communication are connected simultaneously between the signal points of the garage and the main control system of the hoist, including the "watchdog" signal that continuously monitors the main PLC;
