自动化技术在工业、农业、国防、科学实验和社会生活的各个方面获得越来越广泛的应用,产生了深刻的影响。特别是在工矿企业及智能大厦中,自动化技术已成为必不可少的一部分。自动化系统的发展,受到以下几项关键技术的影响:(1)先进的电子技术;(2)固态微型传感器技术;(3)新型的封装和安装技术;(4)数字化现场通信技术。 1 先进的电子技术先进电子技术的发展,使嵌入式系统的选择越来越大,单片机,DSP以及FPGA等技术互相渗透,取开补短,而集成度越来越高,一个芯片往往集成了多种功能,如A/D转换,同/异步串行通讯、PWM、I~2C以及SPI接口等,有些微处理甚至还具有以太网接口。 2 固态微型传感器技术 (1)新型传感器新的敏感器件,新的物理、化学、生物效应的应
The ever-widening application of automation technology in all aspects of industry, agriculture, national defense, scientific experiments and social life has had a profound impact. Especially in industrial and mining enterprises and intelligent buildings, automation technology has become an indispensable part. The development of automation systems is influenced by the following key technologies: (1) advanced electronic technology; (2) solid-state micro-sensor technology; (3) new packaging and installation technologies; and (4) digital field communication technologies. An advanced electronic technology The development of advanced electronic technology, the choice of embedded systems is getting bigger and bigger, single chip, DSP and FPGA and other technologies to penetrate each other, remove the shortcomings, and higher and higher integration, a chip is often integrated A variety of functions, such as A / D conversion, synchronous / asynchronous serial communication, PWM, I ~ 2C and SPI interfaces, and some even have an Ethernet interface micro-processing. 2 solid-state micro-sensor technology (1) a new type of sensor new sensitive devices, the new physical, chemical, biological effects should
