一种全CTC的数据采集接口

AN INTERFACE FOR DATA GATHERING WITH THE COMPLETE USE OF CTC

针对海洋大面积测温航空遥测技术,研制了一块数据采集与MDR-Z80计算机的接口.其中设计了电原理图和相应的软件.该接口电路由于全采用Z80-CTC芯片,对采集时间、计算延时等参数极为灵活,大部份自动采集均靠硬件实现,因而使CPU占用时间极少,这对于一般的芯片组成多通道的采集极为有用.软件用高级语言和汇编语言结合编程,使采集与输出易于实现,同时也是一种实用的测试接口.

In accordance with the aerial telemetry of the temperature measuring oflarge areas of oceans, a kind of interface with its own circuits and software for data aquisilion on MDR-Z80 computer has been developed by us. Since the interface fully uses 280-CTC chips, so the parameters for aquisition and delay arc much flexible, and the majority of the automatic aquisistation processing is realized by the hardware, thus it will take much less CPU lime. It is cxtrcmly useful for the multichannel aquisilion systems consisting of general chips, and the software developed by advanced language and assembly language facilitates the realization of aquisition and outpul. Tl is also a useful inlcrfacc for general measuring.
