Different Characteristics

The paper discusses the application of the wireless data transmission in the industrial control system and analyses the characteristics of the data transmission. It gives the different characteristics of data transmission in the four experiments with the Zigbee Protocol. By comparing the result of the wireless network-path loss model and experiments, it shows that the path loss, multiple-point jamming, communication barrier primarily affect the stability of data transmission.

Set Up

It discusses the reasons of the data transmission time delay and packets loss based on the theory of net data transmission. Aimed to the question of the time delay of data transmission and packets loss, the control system models are set up to analyze their influence to the performance of the control system. Based on the synchronous control model analysis with wireless data transmission, a method to control the system is reached with the state prediction when the communication error or data loss appears. It can control constantly when communication errors appear, and also it can get the most error period by numerical analysis.

Fire Alarm System

In this paper, in order to achieve real-time remote monitoring of fire site, we designed a intelligent remote fire monitoring system based on ZigBee network and GPRS network. This system, used ZigBee and sensor to build data acquisition and short distance transmission network and combined with GPRS wireless data transmission and SMS alarm ,cooperates with the server and PC to build a remote monitoring scheme based on GRPS.
