Improvements for Communication of Wired Instrument Networks
Spread spectrum communication technology can effectively improve anti-interference ability of industrial field instrument networks which is based on baseband communication. However, this raises several aspects of problems, including the decline of communication speed, severe attenuation of signal, dissatisfying the requirements of intrinsic safety and synchronization between the sending and receiving sides. This paper gives the following solutions and verifies their effectiveness by simulation: (1) . Multiple data bits are converted into multiple virtual source, then are spreaded spectrum and mixed. (2) Use pure digital communication instead of analogdigital combination communication. (3) The data packet is added Leader code to achieve synchronization.
