MCU-Based Driven Design for the Electromagnetic Valve of the Repeated Impact Testing Machine

Abstract:

In view of repeated impact condition, developed a repeated impact test machine. This study focuses on using MCU (Micro Controller Unit) to control output of electromagnetic valve what is the core of the machine. The square wave signal , what is issued by AT89s52 and whose cycle and duty cycle can be adjusted, is used to control relay, thereby to control electromagnetic valve of the machine, and ultimately to realize multi-frequency repeated impact under the control of MCU system. A MCU control circuit system is designed at the aim of relay response, including control circuit of hardware, process design of software and anti-jamming design.
