The system uses dual-CPU control, host and from the CPU machines are used SPCE061A SCM. From the CPU is responsible for collecting data on seven, while the main CPU response sent the order. The main CPU for data processing, data show that the keyboard input, voice prompts, voice broadcast channel voltage value. In the main CPU and the communication from the CPU, the use of international standards of the way RS485 differential interface to enable communication and the rate of transmiss ion distance was greater than the standard RS232 interfaces, and the use of at least (as long as two).
Implementation of the system with a broadcast voice, the voice prompt, high-performance, high intelligence of practical long-range multi-channel data acquisition system.
