摘　　要：结合CPLD与单片机设计了一种数据采集控制系统。A/D转换采用ADC0808芯片,转换精度为8位;方位采集通道为水平方向和俯仰方向,具有错误报警、焦距调节等功能,数据采集具备良好的实时性。该系统实现简单,可靠性好,具有很强的可移植性,可广泛用于全方位、高精度数据采集系统的实现。Design of data-collected of controlled system based on CPLD and microcomputer in this paper. ADC0808 is A/D transition chip, the conversion precision is 8 bits. Orientation acquisition channels disparts horizontal and pitching direction,and it has error alarm,focal length setting function. Meanwhile data acquiring system has good real-time. This data-collected system is easy implementation, good reliability, high-amplitude portability ,so it can be applied to data acquisition system which calls for omnidirectional and high precision implementation.
