摘要
化成充放电是蓄电池生产的关键工艺之一,其控制过程直接关系到产品的质量。本文论述了一种支持4路充放电设备控制的多回路嵌入式控制器的硬件结构与软件实现。控制器以单片机为核心,采用点阵LCD汉字显示,系统与过程全部采用光电隔离、串行接口来实现信号转换,结构紧凑、功能齐全,充分体现了嵌入式系统的特点,配以RS485串行通信接口,连接至监控计算机构成分布式控制系统。应用表明系统设计合理,能满足不同过程需要。
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.
