| The traditional8-bit microcontroller as the core to control the grain situationmonitoring system exists many defects, such as less test functions, low reliability,system upgrade difficulties, maintenance costs. With the development of scientifictechnology and the popularity of Internet，the traditional human monitoring system forrice storage is taken place by much convenient and high accuracy monitoring andcontrol system．Based on the single computer technology used for local measurementand contro1．the whole measurement and control system call be linked together byInternet Web visiting method. Administrators are able to understand differentenvironment conditions much faster and easier, and they can change the environmentby controlling motors．This thesis introduces the design of a modem measurement and control systemfor rice storage based on ARM embedded developing board． After the signalscollected by sensors of the measurement and control system，the data is processed anddisplayed on the webpage and the LCD of embedded developing board．By TCP/IPprotocol，the real time data can be monitored through IE browser, and the data alsocan be saved and printed．Moreover the devices like motors can be controlled to workby the button click in the webpage．The hardware system uses ARM9microprocessorS3C2410．in the way of core board and basic board．it can collect multi-channelanalog and digital signals．The hardware system supports standard RS232interfaceand USB interface．and it supports the human-computer interaction interface of LCDdisplay and touch screen, which provides a good monitoring and control interface forthe operators．The software system works in the mode of cross compile，based onembedded Linux OS．The sensor drivers and motor control program are complied in Cprogramming language．The remote monitoring and control system is set up with BoaEmbedded Web Server and SQLite Database．And the terminal interface program isworked out using QT/E graphic software system．... |
