Design Of Control System Of Demolition Device Of Waste Lead-acid Battery

The development of the corresponding control system is to change the current situation that the automation level of the lead-acid battery breaking device is not high.The performance of the control system and the level of automation directly affect the overall performance and efficiency of the breaking device,which has an important guiding significance to improve the market competitiveness and efficiency of enterprises.The control system is mainly designed by PLC as the lower computer,using KingView to develop the upper computer monitoring system.The hardware is mainly composed of master station controller,slave station controller,driver and stepper motor.The control system of upper cover and shell bottom breaking unit adopts PLC to send high-speed pulse.The software design includes the design of lower computer software and the development of monitoring configuration system.Based on the mathematical model of the control system,this paper analyzes the technological process of the six stations,uses S7-200 smart PLC programming software to control the number of pulses by comparing the command control time,and compiles the PLC control program of the demolition system,and finally realizes the software design of the lower computer.The motion control module is used to write the PLC control program,which is convenient to adjust the pulse number,direction and frequency.Finally,the software design of the lower computer of the upper cover and shell bottom breaking unit is completed.According to the parameters of breaking device and stepping motor,the number of pulses received by the driver is calculated.The battery contains heavy metal lead and corrosive acid and other harmful substances,which threaten the health of human body.With the help of Kingview software,monitoring configuration system is developed,including login system,alarm system,security inspection system,main control and monitoring system,parameter setting system,historical report query system and sub monitoring system for six stations.Simulate the mechanical movement system of breaking equipment and develop the simulation test system.The communication between the monitoring system and the test system is realized through Kingview OPC,and the monitoring configuration system simulation test experiment is carried out.The monitoring system information transmission,sending instructions,historical report query,alarm and real-time monitoring and other functions are realized.The workshop field equipment is simulated in real time and automatically jumps to the next station.The experimental results show that the whole PLC control system can run according to the predetermined logic sequence.The running time node of the stepper motor is consistent with the expected value,and the motor speed error value is between ±2%,which is in line with the expected results.Through the control system of upper cover and shell bottom breaking unit,different pulse number,frequency and direction can be set.The upper cover and shell bottom of battery with length range of 227mm?258mm,width range of 164mm?174mm and height range of 200mm?228mm can be cut.The moving distance error is between ±2%,which improves the stable operation speed and meets the accuracy requirements.
