针对井下的安全生产管理信息采集,采用DSP和CPLD技术设计研究一个信号采集与编码系统。系统由四个模块构成:DSP核心处理模块完成多路模拟信号和数字信号的采集、存储和处理;CPLD控制模块用来生成系统各模块所需的译码电路和控制信号;模拟信号采集模块和数字信号采集模块是系统与外部信号的接口。
Aiming at the underground safety management information collection, a signal acquisition and coding system is designed and researched by DSP and CPLD technology. System consists of four modules: DSP core processing module to complete multiple analog signals and digital signal acquisition, storage and processing; CPLD control module used to generate the system required for the decoding circuit and control signals; analog signal acquisition module and Digital signal acquisition module is the system and external signal interface.
