[Abstract]:With the improvement of social development level, energy plays an extremely important role in people's daily production and life. The coal resources are abundant in our country, all over every corner of our country, as the lifting system of mine "throat". It is the hub of transportation staff and equipment, and plays a particularly important role in the daily production and life of mining enterprises. In order to ensure the safe and reliable operation of the hoisting system, in recent years, the research of the electronic control system of the hoisting device has received extensive attention from all walks of life, and a large number of research institutions and universities have also carried out a lot of research on the various electronic control links of the hoisting device control system. In recent decades, in most mine production accidents in our country, the casualties and major equipment damage accidents caused by lifting wire rope loose rope occupy a large proportion, which brings great economic and personnel losses to the mine production enterprises. The traditional loose rope protection device of lifting system mostly uses the stroke switch to detect the fault, this kind of loose rope protection device has low sensitivity and many faults. Therefore, improving the safety performance of loose rope protection device has become an important topic of discussion and research in recent years. In view of the present situation of loose rope protection system of lifting device in China, a set of electronic control system for loose rope protection of lifting device with high reliability and good control performance is studied and designed by using programmable logic controller (PLC) and sensor technology. The main contents of this paper are as follows: firstly, the mechanical model of the loose rope protection system of the hoist is established, and the pulling force of the wire rope during the lifting process is analyzed, and the minimum tensile force of the loose rope in the lifting system is found out. It provides the theoretical basis for the design of electro-mechanical sensor. Secondly, the hardware and software of the electronic control system for loose rope protection of lifting device are designed respectively. In the aspect of hardware, this paper mainly studies the electronic control system of loose rope protection with PLC control as the core, takes the force value measured by the sensor as the basic control quantity, designs the applied electric sensor, and analyzes its working principle. The Autodesk inventor ANSYS Workbench Lab VIEW and MATLAB software are used to analyze and simulate the related components of the sensor. The PLC selection and the peripheral hardware part of the lifting system are designed. In the software aspect of the control system, the MCGS embedded version configuration software is selected to draw the configuration running picture of the lifting device loose rope protection electronic control system, according to the requirements of the control logic of the electronic control system, The control principle diagram of the loose rope protection electronic control system is designed and the PLC port connection diagram is designed. At the same time, the PLC control program of the electronic control system is compiled by PLC programming software STEP7 and simulated and debugged by S7-200 simulation software Simulation. Build the experimental platform, through the laboratory simulation experiment to detect the realization of the electronic control system functions. The experimental results are in agreement with the theory and practice, which shows the feasibility of the electronic control system of the loose rope protection. The experimental results show that the software and hardware of the system can meet the requirements of the electronic control system, and the stability and reliability of the loose rope protection system are greatly improved. At the same time, the sensitivity and safety factor of the system are improved, and the system has a good industrial prospect.
