The Design of Echo Simulator Equipment of Laser Fuze Based on LabVIEW

Echo simulator equipment of laser fuze is an important part of laser fuze testing equipment.The structure of echo simulator equipment of laser fuze is introduced,and the software controlling system and circuit for the echo simulator equipment of laser fuze are designed.The single chip computer used in circuit is used for receiving controlling instruction and producing controlling signal.By using serial port's expansion chip GM8125,the design expands single chip computer AT89S52's serial port into five sub-serial ports.It satisfies the requirement of serial port resources for echo simulator equipment of laser fuze.The software controlling system is designed based on LabVIEW,including the program of serial port communication and controlling instruction.The controlling instruction is transmitted to circuit by serial port communication.The results of experiment indicates that the equipment satisfies the requirement of laser fuze testing system.
