【摘要】 本文以MCS51系列单片机为CPU,设计出能实现8位PC104总线大部分功能的主板,开发了以太网接口,再组合商业PC104总线接口模块形成测控系统。与使用基于X86处理器的标准PC104主板相比,优点是开发与应用简便,成本较低,适合低速测控系统的设计与开发。已经应用在ZDZ型质谱的测控系统中。发展趋势是开发基于32位单片机的PC104主板。更多还原

【Abstract】 Using MCS51 series single-chip microcomputer as CPU,a mainboard was designed,which implements most functions of 8-bit PC104 bus and has an ethernet interface.Combined with commercial PC104 bus interface modules,an entire test and control system was constructed.Compared with standard PC104 mainboard based X86 CPU,the proposed mainboard features simple development and application,lower cost,and is suitable for the design and development of low speed control systems.The developed mainboard and system were applied in the control sys- tem of ZDZ mass spectrometer.The trend of the technology is to develop advanced PC104 mainboard based a 32-bit microcontroller.更多还原
