多回路分散型嵌入式電池化成充放電控制器

摘要：化成充放電是蓄電池生產的關鍵工藝之一，其控制過程直接關系到產品的質量。本文論述了一種支持4路充放電設備控制的多回路嵌入式控制器的硬件結構與軟件實現。控制器以單片機為核心，采用點陣LCD漢字顯示, 系統與過程全部采用光電隔離、串行接口來實現信號轉換，結構緊湊，功能齊全，充分體現了嵌入式系統的特點，配以RS485串行通信接口，連接至監控計算機構成分布式控制系統。應用表明系統設計合理，能滿足不同過程需要。 敘詞：微控制器　嵌入式系統　串行接口　多任務 Abstract： Charge/Discharge chemical processing is important to storage battery production. This paper presents hardware and software scheme of an embedded controller system, which can control four charge/discharge devices and operate in distributed architecture. With Atmel MCU and a dot matrix LCD Chinese characters display introduced, a reliable compact controller is developed via photo coupler isolated serial interfaces for process input and output. And a RS485 communication interface contributes to network of distributed system for centralized supervisory control. The applications of the controller indicate that the system functions are well for different battery production processes. Keyword：Micro-controller　Embedded system　Serial interface　Multi-tasking
