Based On Particle Swarm Optimization Jig Air Valve Control Technology Research And Design Optimization

In recent years, the rapid development based on the premise of gravity beneficiation jig beneficiation has also been considerable development, and in the position of gravitational gradually get attention. Jig beneficiation process has the advantage of simple and easy. The main problem in the past to determine the experience of the operator in accordance with measures to deal with the experience of each operator are different degrees of difference, resulting in a final jig sorting efficiency also have different degrees of different.In this paper, the jig as the research object, according to the research results at home and abroad in recent years, affecting the jig separation efficiency factors and operating variables were analyzed to design a jig automatic control system based on fuzzy control technology jigging damper parameters for real-time online monitoring machine and adjust the main work is as follows:1. Analysis of operating variables jigger, gives the system control requirements.Through the jig bed stratification studies to determine factors affecting the jig with a bed sorting, such as the structure and out of the wind, the size of the water, jig, jig frequency size, etc.; using ultrasonic sensors and the combined share of buoys approach to the height and jigging room bed water level detection.2. Research program to determine the fuzzy controller, using particle swarm optimization controller parameters optimization function(membership function, etc.)to optimize the processing, input select fuzzy controller for a loose valve Jig Jig degree deviation e and loose deviation change rate ec, the scene of years of research experience aggregated to write a fuzzy controller fuzzy control rules, fuzzy controller output to be adjusted to make the jig damper valve cyclically adjusted to achieve the final with solid state relay output section of the electromagnetic damper control.3. Jigger damper on fuzzy control hardware part through analysis and design,selection of Siemens S7-1200 series PLC, through S7-1200 programming software STEP 7 basic10.5, the jigger valve control system hardware configuration, and the PLC programming, including the bed of the data collection process, loose calculation process, the fuzzy controller output processes.4.S7-1200 and HMI communication via Ethernet connection, the jig air valve of fuzzy control system for real-time monitoring.output, etc.Through laboratory testing and commissioning work to prove the feasibility of this system is used in the industrial field.
