(Temperature Data Acquisition And Analysis For Agriculture Farming Intelligent System)

The temperature is accused one of main parameters in the industrial control, specially in industries and so on metallurgy, chemical industry, building materials, food, machinery, petroleum, has the decisive function. Therefore the temperature survey in the industry, the agriculture, professions and so on national defense has the widespread application, for example in industrial production scene control instrument, numerically-controlled machine tool and so on.Takes the lower position machine hard core by at89S52monolithic integrated circuit, controls to32group temperature signal gathering, and makes processing to signal data of the temperature, then realizes the lower position machine through the serial port communication’s way and the superior machine communication, thus realizes the lower position machine gathering temperature signal data transmission to the superior machine. In the superior machine aspect, the use high-quality machine language write program’s method, manufactures the corresponding data statistics and the analysis software. The system is develops under the Delphi environment, the system demonstrates signal data of the temperature that lower position machine gathering on the software contact surface; Using the technology of Database, the lower position machine gathering signal data of temperature storage, and records gathering’s time; Carries on the demonstration to the temperature signal data by the diagram of curves form; Through to the serial port, the mailing of establishment address, the baudrate, the data position and so on, chooses and the control lower position machine as well as the lower position machine to temperature signal gathering; Carries on the establishment to the sampling precision, namely the establishment data sampling time interval, satisfies the different instrument, equipment’s request; Has the warning mechanism, through the establishment, can examine the temperature signal surpasses outside the establishment scope, carries on the warning, in the temperature demonstrated that on the contact surface carries on the demonstration, and has the warning sound. The maximization has realized demands and so on temperature examination, digital demonstration, information storage and real-time control, regarding the enhancement production efficiency and the product quality, the frugal energy and so on has the vital role.
