如今存在着许多联结分布测量与控制系统中换能器(传感器与执行器)的控制网络.微处理器的主要职能是:运行网络协议包,提供控制环或过滤算法之类的专用功能,获取传感器读数及控制执行器.传感器制造商面临这诸多选择,一般会出现以下情况:开发能与控制网络直接相连的传感器或执行器.这样做需知道协议和通讯收发器的专用网详细资料,还要把换能器及信号处理元件集成于可联网的应用处理器(简称NCAP).这种支持必须对零售商希望支持的每一个网络 Today there are many control networks that link transducers (sensors and actuators) in distributed measurement and control systems.The main functions of microprocessors are to run network protocol packets, provide specialized functions such as control loops or filtering algorithms, Sensor Reading and Control Actuators Manufacturers of sensors are faced with a number of options that typically arise in the development of sensors or actuators that can be directly connected to the control network.There is a need to know the details of the private network for protocols and communication transceivers Integration of transducers and signal processing components into a networkable application processor (NCAP) requires support for every network that retailers want to support
