Design Of Remote Temperature Monitoring System Based On Embedded Web

In times of peace, the majority of ammunition for the army is stored in the warehouse fora long time, how to guarantee the safety of the stored ammunition is therefore the main task ofthe ammunition warehouse safety management. There are many factors which influence thesafety of the stored ammunition，the temperature is one of the most environmental factorsaffecting the safety of the stored ammunition, because the safety accident caused bytemperature factor accounts for a large proportion of the total accident. At present, thetraditional measuring instruments are still used in the ammunition warehouse safetymanagement work in the grass-root units. With the depth development of military informationconstruction, the traditional monitoring instruments have been unable to effectively meet theneeds of information storage and management. For this situation, this thesis designs one kindof temperature monitoring system which based on embedded Web technology. We canmonitor dynamically the temperature change of the ammunition warehouse by using thesystem, and this could provide technical reference for improving ammunition storage safetymanagement in the grass-root units. This thesis has mainly completed the following works:First, a solution for remote dynamic monitoring temperature has been designed. Thisthesis selects embedded microcontroller processor S3C2440AL-40of Samsung andtemperature sensor DS18B20of Dallas as the hardware, Windows Embedded CE6.0ofMicrosoft as the embedded operating system, and realizes the remote dynamic monitoring oftemperature by building Embedded Web Server.Second, customization of the embedded operating system has been completed.According to the needs of user, Windows Embedded CE6.0has been customized, mainlyincluding addition of the functional components such as communication protocols, filesystems, storage components and other components, and then the operation system has beencompiled.Third, hardware drivers have been developed. They include the driver for temperaturesensor DS18B20in the S3C2440and Windows Embedded CE6.0environment and the driverof the alarm module.Fourth, application based on Windows CE has been developed. According to the needsof user, the application has been developed, which based on Windows CE for acquisition anddisplay of temperature, and the interaction between users and system has been realized. Thefunctions of the application include reading and displaying in real time the temperature valuemeasured by temperature sensor, displaying change trend of the temperature in a graphicalway, writing the measured temperature value and the time into the USB storage devices,opening or closing the acquisition of the temperature, setting the upper and lower limit value of the alarming temperature, turning on the buzzer alarm module and displaying the alarm intext, intercepting display interface of the application, compressing the size of the screenshotsby the way of format conversion and so on. Among them, the use of the screenshots andformat conversion is to realize the accordance between client browser and applicationinterface. In the end, temperature measurements in the local have been done for analyzing theperformance of the system.Fifth, Web publishing for temperature monitoring situation has been realized. In order toobserving the change of the temperature over great distance throughout the web browser, thechange of monitored value of the temperature is published in the local area network bybuilding the Embedded Web Server in the embedded system, which designed in this thesis.This would provide decision-making reference for ammunition warehouse safety managementwork.
