本文介绍了在Apple-Ⅱ机上开发气象传真资料接收系统的应用软件及接口电路。用软件实现的同步过程简单可靠。系统采用中断方式,为进一步开发应用留有很大余地;数据采集与移位变换一步完成,为数据的压缩处理提供了方便。
This paper introduces the application software and interface circuit for developing meteorological data receiving system on Apple-Ⅱ machine. The software synchronization process is simple and reliable. The system uses interrupt mode, leaving a lot of room for further development and application; data acquisition and shift transformation is completed in one step, which provides convenience for data compression processing.
