20世纪70年代初,我国引入工业有线设备,但是随着科学水平的进步,工业生产自动化的提倡,工业无线技术逐渐开始在工业生产过程中得到应用。工业无线技术可以有效避免有线通信对于工业自动化的各种限制,能够有效的减少线路铺设的各种人力投入,以及在后期各种维护的投入等。本文就基于这一点,对几种无线技术做了详细的阐述,对比其优缺点,以期为工业自动化选择最做的无线技术作参考。 In the early 1970s, China introduced the industrial wired equipment, but with the advancement of science and the promotion of industrial automation, industrial wireless technology gradually began to be applied in industrial production. Industrial wireless technology can effectively avoid the wired communications for industrial automation of various restrictions, can effectively reduce the laying of a variety of manpower input, as well as in a variety of future maintenance inputs. Based on this point, this article elaborates on several wireless technologies in detail, comparing their advantages and disadvantages, with a view to selecting the most advanced wireless technology for industrial automation as a reference.
