[Abstract]:With the development of sensor technology, sensor has the characteristics of high precision and low cost. At the same time, Internet technology is developing rapidly and serving our daily life. Sensor technology and network technology combined to form the Internet of things technology. The application of Internet of things technology in daily life and industrial and agricultural production has become a trend of development, and has a certain development basis and successful cases. Based on the development of sensor and embedded technology, this paper introduces the research background of embedded large-scale temperature acquisition system based on wireless network, and the practical significance of developing this system. At the same time, the development of the core technology used in the system at home and abroad is briefly analyzed, including embedded technology, sensor technology and other hardware-related core technologies, as well as embedded software. Embedded database and software related technology such as B / S model. Then the system is analyzed based on technology, function and requirement. This paper designs the whole system from the point of view of function, including hardware design, software frame design, database design and related business process design. Finally, the related functions are implemented according to the system design, and each function is verified and tested, which ensures and verifies the feasibility and practical value of the system. The embedded large-scale temperature acquisition system based on wireless network is a system which combines the temperature sensor suitable for different needs with the traditional wireless network and integrates the functions of acquisition, storage and management. The temperature sensor combines the low-end embedded chip to form the collection part of the system, which has the function of data acquisition, completes the task of collecting the field data, and the high performance embedded chip with the database and other software components constitute the data storage part of the system. With data receiving, storage and authority management functions, complete the system to identify equipment and data management tasks. The system can bear the demand of large-scale acquisition, which is mainly reflected in the range of spatial distribution and the number of acquisition points. Because the system adopts wireless network as the mode of data transmission, the system has a wide range of spatial distribution of data acquisition. Break the traditional wiring limit. At the same time, the data receiving and storage part of the system uses high performance chip, which can support as many as 5000 points. The data storage and management part of the acquisition system adopts relational database and provides the standard interface to the outside world. It has good compatibility and convenient docking with other application programs. The system uses time-based one-time cipher to verify the legitimacy of the equipment, which effectively ensures the security of the system. At the same time, the system adopts traditional wireless network, which makes it easier to deploy and change the system topology. For the user access mode, the system adopts the B / S design pattern to provide users with friendly access and management interface, which is convenient for the system function expansion and secondary development. In addition, the system classifies visitors based on permissions to ensure the security of system functions and data on the application layer.
