Research On Embedded Interface Of Internet Of Things

With the development of Internet and the rise of Interent of Things, embeddedtechnology also get more extensive used, the Internet of Things in embedded field hasbecome a trend. As the improvement of people’s living standard, the local and signalmode of remote monitoring can’t meet the demand of the market, it is becoming moreand more networking. This paper complies with the network development trend,changes the traditional remote monitoring mode, based on embedded technology,researched a remote control system which based on GSM/GPRS and embeddedInternet technology and strives to bring out an integration, intelligence, generalization,low cost remote monitoring platform by combining remote wired, wireless interfaceand multiple local interfaces.Paper takes common network communication technology and embedded interfaceas research object, designed related hardware, firmware and software. Detailed worksare as follows:(1) Embedded interface hardware design. It integrates multiple interfaces on apiece of circuit board, these hardware interface mainly includes wirelesscommunication interface, wire communication interface, serial interface, parallelinterface, custom bus interface.(2) Embedded interface firmware program development. Design correspondingdrivers according to various hardware interface and transplant embedded real-timeoperating systemμC/OS-Ⅱ. These firmware programs include GPRS module driver,simplified TCP/IP protocol stack, serial interface driver etc.(3) PC monitoring software design. Using cross-platform QT ligrary design thissoftware so that to timing control electrical equipment and to collect data from itssubmodule which connect to embedded interface board through wire or wirelesscommunication mode.(4) Smartphone monitoring software design. Design application program whichbased on android system to monitor remote device any time any where. This softwarehas the same function as PC monitoring software.
