Description: 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.
