摘要
利用AVR单片机对发电机负荷缸的多路远程遥控开关量进行采集,对采集到的开关量信号进行数字信号编码,通过RS 232/RS 485串行通信转换芯片实现了串行通信信号的远距离传送,在信号的传输和通讯中采用了握手和数据校验的方法保证了数据的可靠传输和控制。该方法也可用于其他开关状态信号的采集和自动化控制场所,实现设备的智能化监控。
Implemented the Codec and transmission of signals of multiple remote control switches by using AVR single chip computer,a RS232/RS485 converting IC is used for long distance signal transmission. A handshake method and data integrity checking mechanism is adopted to ensure reliable data transmission and control. The method also can be applied to other intelligent control systems.
