With the improvement of the level of social development, energy production plays a very important role in the daily reality of life. Coal resources are abundant throughout our country. As the "throat" of the lifting system, the transportation of personnel and equipment supplies, plays a very important role in the daily mine production and life. To ensure the lift system’s safety, in recent years, the study of electrical control system of lifting device extensive attention, major research institutes and universities also make a lot of research. In recent decades, most of the mines in our country, broken rope accidents caused frequently, give nine production enterprise to bring significant economic and personnel losses. The traditional loose rope protection device of hoisting system mostly use the traval switch to detect faults, is low sensitivity. Therefore, to improve the safety performance of the loose rope protection device of hoisting system is becoming an important topic. In order to enhance the status quo of the loose rope protection device of hoisting system, using the programmable logic controller (PLC) and sensor technology, research and design a higher reliability, better control performance of the lifting device loose rope protection electric control system. The main contents of this paper are as follows: First, establish a mechanical model of the lifting device loose rope protection electric control system, full analysis of the hoist rope in the process of upgrading suffered tension, find out the minimum tensile to improve the system, provide a theoretical basis for the electrical sensors design; second, respectively to improve the protection of electrical control system design. On the hardware, the main research is the PLC control, use the value measured by the sensor as a basic control amount effective to design the electrical force sensor, analyze the working principle and the use of Autodesk Inventor, ANSYS Workbench, Lab VIEW and MATLAB software to simulate the related components of the sensor, PLC selection is used to enhance the system and the peripheral part of the design of the hardware. In the control system software, PC software select MCGS embedded version of configuration software, draw a picture of the lifting device loose rope protection electric control system; according to the control logic of the electronic control system, design the electrical control systems, PLC port connection diagram, and use the PLC programming software STEP7 prepare the electronic control system with PLC control program and S7-200 program simulate and debugging; Finally, set up the experimental platform, through laboratory simulation experiments to detect the achievement of the various functions of the electronic control system. Experimental results consistent with theoretical results, show the feasibility of the electronic control system. Experimental results show that the system's software and hardware meet the needs of the electronic control system, the stability and reliability of the protection system be greatly improved, and also to increase the sensitivity and the safety factor of this system, has good industrial prospects.
