| Abstract: | There were mainly 5 parts in the test platform of machine vision seed-meter test-bed,which were transmission strap system,motor and its drive system,machine vision system,PLC control system and control center in this paper.The test-bed used contactor and PLC to control the electric system and realized frequency control by using PLC to control the transducer.It could realize auto control of the motor speed by combining the computer in the control center.We designed the main circuit,the control circuit,PLC ladder diagram and relevant repertoire according to the request of the electric system.By experimental test,the whole control system has stable performance and reliable work,and satisfies the design require. |
