摘要:

自動(dòng)化設備的廣泛應用是工業(yè)現代化的重要標志之一,隨著(zhù)應用環(huán)境的逐步復雜和應用需求的不斷提升,實(shí)現可靠的多測點(diǎn)信號采集具有重要意義;針對自動(dòng)化設備多點(diǎn)信號采集的實(shí)際需求,設計了基于CAN總線(xiàn)(CANopen協(xié)議)的分布式控制系統；使用ATmega16單片機實(shí)現了多測點(diǎn)的4~20 mA電流信號采集的軟硬件設計,并根據工作應用的實(shí)際需求,從軟件與硬件兩方面提出了更加具體的優(yōu)化方法以提升系統性能;最后,利用搭建的實(shí)驗平臺,進(jìn)行整體系統的精度實(shí)驗,并完成相應的數據處理與分析;實(shí)驗證明該系統能夠進(jìn)行可靠穩定的多測點(diǎn)數據采集,具有一定的應用參考價(jià)值。

Abstract:

The extensive using of automatic equipment is one of the most important symbol for industrial modernization. With gradual complex of environment and increasing improvement of demand, it is significant to realize reliable multi-point measurement. Considering the actual demand of engineering, the distributed control system based on CAN bus (CANopen protocol) was designed. In terms of the architecture for the control system, the hardware and software for this system were designed and implemented based on ATmega16. Considering the practical application, more methods are proposed to optimize the performance of system. Finally, based on the prototype, the system accuracy experiment was conducted, and the data was processed and analyzed. The experiment prove the system could realize the reliable measurement, it has a certain reference value.
