Network Of Environmental Monitoring System

In order to improve the running efficiency and safe coefficient of modern telecommunication network, ensure switching equipments which built in huge domestic investment run safely and efficiently, it is very important for us to monitor and control all sorts of environmental parameters remotely (such as temperature, humidity, fire alarm, thief alarm and so on).In this paper, a protocol converter technology for RS232/485 -TCP/IP based on a single-chip processor and a multi-channel data acquisition technology through V/F are researched successfully. And in terms of these two kinds of technologies, a fundamental network environmental monitor and control system is realized. In the condition of limited resources of a single-chip processor, TCP/IP protocol is cut efficiently. Furthermore, the network environmental monitor and control system built in this paper not only can accomplish local environmental supervision, but also can be available to connect with a large network environmental monitor and control system which based on Ethernet environment.
