摘要
用单片机最小系统为核心设计电路主板,以替换简易电动显示调节仪表老产品,使仪表屏的开孔尺寸可从原标准76mm×152mm缩小至45mm×92mm。新仪表在性能和外形上可与进口同类产品互换。论述了仪表研制中的数据采集、接口、数据处理与抗干扰等关键技术。
The main board with Single-Chip Microcomputer Minimum System is used instead of the old instrumentation product of simple electromotive regulator. The cut-out dimension for a single instrument is reduced from original 76*152 (mm) to 45*92 (mm). The new instrumentation may be interchanged with foreign products similar in shape and property. Some Key technologies, such as data acquisition, circuit interfacing data processing, antijamming etc are briefly presented.
