Because the extensive management of the tradational agriculture hinders the development of the agriculture,we advise the system based on the inteent of things,which design and implent the crop growing enviornment.This article describes the meaning and the functions of the system in details,which also describes the architecture ,hardware components and software design.The design of the system promotes the rapid development of the precision agriculture.

The Yellow River Delta National Agricultural Science and Technology Park proposed the concept of "One Zone One Hundred Parks", namely the Yellow River Delta National Agricultural Science and Technology Park consists of a hundred geographically dispersed agricultural technology demonstration park. In order to effectively provide intellectual support for these geographically dispersed agricultural technology demonstration parks, this paper presents the design and the idea of remote crop image capture and expert systems. The core idea is to set up image collection terminals in a decentralized agricultural technology demonstration park. Crop samples are collected by the terminals, using GPRS network to transfer the captured image data to the Key Laboratory of Agricultural Bioengineering. Agricultural experts make an analysis to image samples, and propose treatment advice. And then, the experts feedback the advice to the various agricultural technology demonstration parks. After a year of testing, the entire system is reliable, excellent performance in real-time transmission of images. This system has played a very important role in the prevention and control of crop pests and crop growth guidance.

The paper introduces the design and realization of gateway node for the smart home system based on Internet of Things. With the development of smart home based on internet , the gateway node as an important part has become a hot issue in the present study. The paper describes the functions,analusis the hardwares constitutions and softwares design. At last,it points the main problems and the developing direction.

For the design of storagebox control system supplied to fixed customers , this paper presents the designideas that the storage box controlsystem based on fingerprint identification.The core design philosophy is basedon the PC as the core, connecting the fingerprint recognition module and thepower locks array control systems through two com ports. through the smalldatabase system on the PC, it can manage the two moduls effectively.When theuser's fingerprint match, the fingerprint identification module returns to thePC a finger signal,the small datebase will correct the electricity lock of theusers,PC then transmit this signal to MCU,then it starts the appropriateelectricity lock.After a long time operating ,this system can works much stableand reliable.
