摘要
利用USB接口技术,采用USB100模块与高性能单片机W77E58结合设计了两种核谱测量系统与微机的接口方法,实现了核谱测量系统的实时数据采集。由于USB100模块已经封装了USB协议,接口非常简单,对于微机系统它是COM3或COM4,对于单片微机或其他信号处理单元它是一个简单的I/O端口,使得新一代的核谱测量系统可以非常方便地从ISA、RS232总线转向USB总线。对于采用RS232的测量系统,微机系统的测量程序可以完全兼容新的USB测量系统,稍作修改既可充分发挥USB接口的优越性能。
This paper introduces applying of USB technique and constructing nuclear spectrum acquisition system via PC's USB interface. We choose the USB component USB100 module and the W77E58 μc to do the key work. It's easy to apply USB interface technique, when USB100 module is used. USB100 module can be treated as a common I/O component for the μc controller, and can be treated as a communication interface (COM) when connected to PC' USB interface. It's easy to modify the PC's program for the new system with USB100 module. We can smoothly change from ISA, RS232 bus to USB bus.
