| Based on the study and analysis of the remote monitoring system based on the principles and characteristics, were developed practical application platform. After a remote monitoring platform,the actual physical information collection, integration and remote data is transmitted, and then the server collect the data, with the final presentation to the user.Firstly, this paper analyzed medical refrigeration equipment for the shell model, and then analyzes the equipment from the inside to the outside,and the sensor parameters is in the equipment.Analysis of different transmission characteristics and application scenarios, and select the suitable communication for the design.Secondly, through the study of ZigBee technology, as well as to analyze the protocol stack.Designed hardware circuitry, and then its protocol stack configuration parameters to be modified,and finally completed the networks based ZigBee wireless LAN. Meanwhile, in-depth understanding of GPRS transmission mode on the remote, complete with ZigBee coordinator for GPRS module control, and data conversion. Such structures completed ZigBee and GPRS network will be able to complete the remote acquisition and send the information to the physical remote.Then, through the Java Web server-side technology, the server-side storage the remote data from GPRS module. When a user accesses the server,the server will saves the current data and the few seconds historical data back to the user. Allowing users to not only know the current data and can make some qualitative judgments related to the data based on historical data.In this paper, through a combination of medical refrigeration devices, and various of functional sensors testing equipment to meet the requirements of the physical parameters. Compared to traditional parametric testing, this design achieve the user wireless access to this perfect user experience, culminating in the medical refrigeration device parameter detection system based on ZigBee and GPRS. |
