Data Acquisition System Of Cavern Based On Embedded Web Server

With the development of information technology, electronic equipment cavernsystems become more and more, the demands of monitoring the environment of caveand the running state of the equipment are higher and higher, the rapid growth ofdata to be collected. Because of this situation, site management is more and moredifficult. In recent years, with the arrival of PC era, the embedded system has widelyinfiltrated into scientific research, industry, military industry and daily life etc..Therefore, the data acquisition system based on embedded system platform cameinto being. Because the embedded technology is more and more favored bydevelopers, the embedded system injects fresh "blood" for the data acquisitionsystem under all kinds of environments. The management and monitoring of armydepot need improvements. It is still using the traditional method based on PSTN forremote supervisory control and data acquisition. This method has a big limitation thatcan not meet the requirements of the development of the army now. According to thecurrent environment of the data acquisition system in domestic and international andthe actual situation of cavern system, this paper provides a new kind of army caverndata acquisition system based on embedded Web server to guarantee the normaloperation of the cavern system effectively.Firstly, this paper shows the development status and prospects of dataacquisition monitoring system. With analysing environment parameters and dynamicforces of army cavern, it provides a monitoring method of data acquisition;According to the comparison of various schemes, the design scheme is determined;The main hardware design consists of S3C6410core control module, digitalmonitoring module, network communication module, switch control module, serialcommunication module; The software consists of communication protocol of remotedata acquisition and the simple network management protocol SNMP. it completes goahead structures, transplantation of embedded Linux and Web server,the devicedriver and Javascript scripts. it designs CGI dynamic interactive forms, the datastorage and processing of database Sqlite.This system not only passes the test in the laboratory environment, but alsoimplements the monitoring of various environmental parameters and data storage inremote machine room successfully. And it provides a new solution for dataacquisition system.
