The Research And Application Of Wireless Test And Control System For Grain Situation

The Wireless Test and Control System for Grain Situation is a kind system that does not need staffs to arrive the scene. It uses grain sensor to transform the grain temperature, humidity, insect pest and so on for granary in situation to data form with specifical transforms (like junction implement), and through the network system which composed by the wireless correspond mode and oneself forms to send out data to test and control extension, and through LOC transmits the data to test and control main engine which will deal with accordingly. Finally, the data arrive on the position machine. The manage system analyse, storage, dispose these data to demonstrate form which we can read directly, through necessary grain sentiment management software. The system also can carry on corresponding processing to the grain and barn to realize the safe memory grain goal through controls facility equipment the ventilator and so on.This article takes Taiyuan Hongtiankemao Limited Company's research and development project-the Wireless Test and Control System for Gain situation as research background, abroad collects and deep analyses massive related domestic and foreign information which contain various technology of wireless communication and control system of gain. On the one hand, from survey accuracy, reliability and function aspect and so on, I have studied the existing wireless test and control system for gain situation in the current market and summarized its good and bad points; On the other hand, I also have investigated in-depth to the domestic and foreign existing wireless communication technology. In this foundation, closely unifies the information which feeds back the industrial production scene, and applies the wireless communication technogoly to survey temperature of the granary and grain. Thus the wireless test and control system for gain situation developed. In the entire design process, first I inspected the market application and the demand situation, and had determined the feasibility of the development for the wireless test and control system for gain situation. According the existing wireless communication technogoly and test and control system of gain technogogy, I unify the theory andthe practice and draw up to have the certain innovation theory and theviewpoint design proposal. I has designed the wireless connection module by the monolithic integrated circuit primarily controller, and have completed the wireless granary grain sentiment observation and controlsystem hardware design and the software design. After the company and the concerned expert's proof approval, I have drewed up the schematic diagram, purchased the primary device, built the hardware electric circuit on the experimental board, then factured the PCB board, chosen the shell, designed the pasted membrane, and carried on the software programming with the C language and the assembly language. Then the whole debugging of system is completed. Wireless test and control system of grain situation which this article designed has the following characteristic: can make the grain control section to understand the grain's storage situation for each granary, and the work like measure for grain and so on can't be infected by time and weather limit; reduce staffs'inspection the frequency for entering the granary, avoid the senseless work load. Especially, in a very long period of time after suffocating and so on, put an end to the probability which the staff scene is poisoned, liberate the productive forces, and also reduce staff's labor intensity and the artificial expense; short wire, few contact, little disturbance, stable circuit, slight damage for suffocating, especially hardly destruction for grain passing in and out granaries, reduce the usual maintenance cost greatly; the application of wireless test and control system for grain situation improves the storage grain condition and makes vital role for promoting socialism new countryside construction through reducing the grain preserve loss, safeguarding grain security and increasing the farmers' income; provide a brand-new kind way to acquire and processe gain information for the people.This topic's research applies wireless communication technology and computer network technology to the test and control system for grain situation. It has realized scientific storage grain and automatic the granary management. And it also has the certain reference value regarding the reform and development of the test and control system for grain situation.
