According to the operation of RS485 communication net and computer real time control to multi purpose monitoring system,this paper analyses the structure design of high speed shock durability test system on auto alternator and describes the characteristics of operation mode in Windows 98 platform.
The system communication net is basing on 10M Ethernet and conformed to TCP/IP protocol. The collection of the input signals in scene and the control of the output signals can be finished long-rangly through this system.
The intelligent control system for pumping wells is an integration of micro-electronic,electrical,computer and communications network techniques. It can achieve automatic control on technical parameters in current,voltage,back pressure,power factor,and indicator diagram,thus providing reliable data for scientific management of pumping wells.
By introducing development,course,peculiarity,structure,framework and characteristic about communications network of DCS,its substantiality and function in DCS is emphasized,intending direction of communications network in DCS is pointed out.
Thus behavioral aspects are for the time being eliminated, and attention is focused exclusively in the properties of the potential communication net itself.
Interest is centered on the communication net which restricts the possible channels for messages.
At every sending time each individual sends all the information he has acquired to one other individual; the major assumption here is that this recipient is chosen at random from the possibilities given by the communication net.
