Description: 利用SPCE061A，RS485 多路数据采集系统
本系统采用双CPU控制，主机与从机的CPU都是使用SPCE061A单片机。从CPU负责采集七路数据，同时应答主CPU发送的命令。主CPU进行数据处理，数据显示，键盘输入，系统报警，语音播报通道的电压值。在主CPU与从CPU的通讯中，采用国际标准的RS485差分方式接口，使通讯的速率和传输距离均大于RS232的标准接口方式，并且用线最少（只要两根）。本系统实现了一种具有语音播报、语音提示的高性能、高智能的实用型远距离多路数据采集系统。-The use of SPCE061A, RS485 multi-channel data acquisition system using dual-CPU of the system control, the host machine s CPU from SPCE061A Singlechip use. From the CPU is responsible for collecting data on seven routes, while answering the main CPU to send commands. The main CPU for data processing, data display, keyboard input, the system alarm, voice broadcast channel voltage. In the main CPU and the communications from the CPU, using international standards, the way RS485 differential interface to enable communication rate and transmission distance were greater than the standard RS232 interface mode, and with lines at least (as long as 2). The system achieved a voice broadcast, voice prompts, high-performance, high intelligence, practical long-range multi-channel data acquisition system. Platform: |
