基于ISA总线接口的B码终端卡设计与实现

摘要

针对车载设备,传统B码终端存在设备体积大、接线多、不利转运等问题,提出一种基于ISA总线接口B码终端卡设计方案,通过ISA总线直线向测控设备监控计算机传输时间信息,减小了设备体积,便于操作,提高了设备可靠性.%For the car-borne equipments, the traditional B-code terminals have many shortages, such as big cubage, more wiring and unfavorable transshipment etc. In order to resolve these problems, a project of B-code terminal card based on ISA bus interface is designed, which directly sends time data to surveillance and control computer by ISA bus. The purposes of less cubage, simple operation and higher reliability are obtained.
