slave signal

Data processing module with a close-coupled master-slave dual processors employs a digital signal processor ( DSP) as its data processor and a micro-controller as its I/ O interface processor.

数据处理模块采用主从式紧耦合双处理器结构，分别以数字信号处理器（DSP）作为数据处理机，单片微控制器作为I/O接口处理机；

STD bus type Master/ Slave CPU intelligent process method is used to realize Large scale switch variable deflection signal testing. The information is processed by using response logical circuit in hardware interface of I/ O testing system.

本文采用了STD总线式的主从CPU智能化处理方法，实现大规模开关量变位信号的检测，在I／O检测系统的硬件接口中采用应答逻辑电路进行信息的处理。

Meanwhile, the function of slave interface is to convert the data from terminal units into M-bus pulse signal according configuration of pulse increment and unit of different terminal instruments.

所设计的从机接口的功能是，按要求发送、接收数据，并将终端仪表的数字信号转化成M-BUS电平信号。

The current ASI special IC can only transmit 4 bit data of switch sensors, I design special slave interface for transmitting more bit data from analog sensor. The master transmits control signal and data signal based on IC separately.

已有的从站专用芯片只能传输4比特的开关量，本文设计了可以传输模拟传感器的多比特数据从站接口，通过专用芯片分时传输控制信号和数据信号。

Firstly, each slave station has a single station operating mode. The master signal and working station signal of each unit are controlled by independent PLC to ensure stable and reliable operation of the equipment.

首先每个从站都有单站运行模式，采用独立的PLC控制，系统稳定可靠。
