Design of a remote stress monitoring system based on GPRS and ZigBee

摘要

In consideration that it is impossible to effectively transmit and promptly analyze the monitored data under variable environment in remote areas, this paper designed a remote stress monitoring system based on GPRS and ZigBee. The lower position machine of system consists of optical fiber sensor module and ZigBee module. The lower position machine will pack monitored the data of stress that optical fiber sensor measured through cascade transmission by ZigBee module. Then, the packed data will be sent by GPRS module of coordinator node to a remote server. The software on the upper computer are written in C# language, on which users can check the monitored data of stress when the client connected with the server. In this way, they can handle the alarms in time and set the alarm threshold of ZigBee through the client for remote wireless stress monitoring of steel on a real-time basis. Stable and economical for transmitting data at a fast speed, this system can completely monitor the stress in variable environment on a real-time basis.
