Design And Implementation Of New Coal Gangue Photoelectric Sorter Control System

At present,coal,as China's main energy source,has firmly supported and guaranteed the sustained and rapid development of our economy.China's coal production is large,but due to the disadvantages of the traditional coal preparation industry,such as the complicated and cumbersome traditional sorting technology,low degree of intelligence,unsatisfactory sorting results,and low effective production capacity,a new type of coal is urgently needed.Coal preparation equipment.Therefore,in view of the new coal preparation requirements and the particularity of underground mining operations,a new type of coal gangue photoelectric sorter based on dual-energy X-ray scanning is designed,and the control system of the new type coal gangue photoelectric sorter is mainly carried out.Design and implementation.In view of the defects and deficiencies of traditional sorting equipment,the analysis of the system structure of the new sorting equipment has completed the main control system,feed control system,signal processing system,and valve-driven sorting control system of the new sorting equipment.the design of.The main control system controls and manages each subsystem of the entire equipment,and realizes human-computer interaction with the sorting equipment through the communication connection of the console.The main control system uses the PIC18F4520 single-chip microcomputer as the controller,CPLD XC95144 realizes the expansion of logic circuits,designs external storage circuits,voltage monitoring circuits,and switch signal circuits;and completes the communication connection circuit between the PIC18F4520 and the console and each subsystem.The feeding control system adopts electromagnetic vibration feeding method.Based on the principle of electromagnetic vibration feeding control,the relationship between the adjustment parameters of the feeder and the power supply parameters is established,and the electromagnetic vibration feeding control system is designed based on this.Design of detection,thyristor trigger and communication circuits.The signal processing system includes an optical system that uses dual-energy X-rays to transmit the object to be detected.The spray valve drive sorting control system uses high-speed solenoid valves and array nozzles to complete the design of the spray valve rejection device.Select the control action circuit.The entire equipment operation process is to use the dual-energy X-ray transmission of the detected object's spectral signal,the signal is processed by the signal processing system and transmitted to the main control system,and finally the main control system controls the spray valve drive through the obtained electrical signal The sorting control system operates to complete the sorting of the detected objects.Through the simulation and debugging of the entire equipment system,the modular design of the equipment is completed,and combined with the built experimental prototype,after repeated debugging,each system equipment has achieved good results,and its identification and sorting accuracy is high,and the processing particles are extremely wide.Figure 60,table 7,para.73...
