Temperature Measurement System Developed Based ARM9 And AD590

Measurement is the nature of a person to understand the scientific method. Through a variety of measurement, the number of people will be able to describe the material around the world, revealed the existence of laws of nature, and promote the constant progress of science and technology. People's daily life, industrial and agricultural production and scientific experiments, and many other aspects of temperature measurement and has very close relationship. Temperature is an important physical, in the course of industrial production is the most common, the most important technological parameters of. With the era of progress and social development, science and technology constantly updated, the temperature range requirements continue to expand, while the temperature measurement accuracy requirements continues to increase. The temperature measurement requirements are also increasing, but also a growing range of temperature detection technology requirements are also getting higher and higher. Therefore, the temperature detection and temperature detection technology research is also an important research topic.The main work is to develop a temperature measurement system based on the ARM9 and AD590 so that it applied to the production of electronic products, food processing, industrial production and other medical equipment production, in the practical application of a very broad prospect. Paper are include:(1) Brief introduced background and significance of the project, introduced the development and application of temperature detection technology at home and abroad.(2) Introduced embedded system and the ARM processors , focusing on the S3C2410 chip.(3) Design the hardware section of the temperature measurement system, and select the appropriate device to achieve. First determine by analysis and comparison to AD590 as a temperature sensor, and then to design temperature acquisition and conversion circuit, A / D converter circuit, the voltage conversion circuit, memory circuit and the specific structure of the serial communication circuit.(4) Select Linux as an embedded operating system of this system, the Linux kernel porting, and achievement of the driver.(5) According to the hardware structure of the temperature detection system, planning out the process of system application. Primarily responsible for temperature data collection and storage management, then send the data by the first crew communication module.(6) Applicat Visual Basic to design and prepare the PC software, that responsible for receiving the data and then convert the data into temperature and displayed and stored in the database.The fundamental research and the experiment analyzes of this paper has great meaning for the practical application...
