摘要
激光测距仪器维修训练系统可满足多种型号测距仪器的测试需求,而激励电源是该系统的关键部件。对基于USB总线的程控激励电压源进行了设计,可调电压源主要由ATmega16单片机与4通道数字电位器AD8403等器件构成,USB通信电路由ATmega16与PDIUSBD12构成,并且在Windows XP系统下开发了相应的WDM驱动程序。测试结果表明该激励电压源能够满足激光测距维修训练系统要求。
A stimulus voltage source is the key component of a laser range finder servicing and training system which can satisfy the testing demands of various types of range finders. In this paper, a programmable stimulus voltage source based on the features of USB bus is designed, in which an adjustable voltage source was constructed by employing ATmega16 MCU, 4-channel digital potentiometer AD8403 and other devices, a USB communication circuitry was accomplished with ATmega16 and PDIUSBD12, and corresponding WDM drivers were developed on the Windows XP system platform as well. The result showed that stimulus voltage source is able to answer the demands of the laser ranger finder servicing and training system.
