[Abstract]:With the rapid development of embedded system, network, wireless communication and other technologies, sensors with the ability of computing, sensing and wireless communication, as well as the wireless sensor network composed of them, have gradually entered people's lives. Based on the mobility performance of nodes, fewer sensor nodes are deployed in the sparse region, and the communication link is established with a certain probability between the mobile convergence node and the perceptual region, which can provide higher credibility and larger scale sensing ability. However, general wireless sensor networks require special convergent nodes to complete interaction with general networks, and some mobile convergence nodes also need to be used in conjunction with professional equipment or professionals. Based on the above practical situation, this topic considers the use of smart phones as convergence node. A mobile phone that installs specific software automatically collects data from the perceptual area when it passes through the perceptual area. Using smart phone sensor, network, Bluetooth and other functions can realize the collection, fusion, reporting and other work of perceptual data. In this paper, the intelligent storage system as the background, developed a set of environmental data perception, storage management, access control system as one of the data collection platform, the main research contents are as follows: (1) designed a set of general wireless sensor network nodes. Extended a rich functional interface, can easily connect a variety of sensors and communication equipment. Ordinary nodes and Bluetooth modules can communicate with smartphones. It is easy to collect perceptual data by using smart phone. (2) A general Bluetooth module with control and operation functions is designed and implemented. The module can communicate with other devices as common Bluetooth, and the CPU of ARM core on board has powerful computing and processing ability. This module is also used as the core control module of the access control system and the communication module in other systems. (3) the UHF RFID reader is designed and implemented, and a variety of extended interfaces are reserved, which can be connected to the computer through the USB interface. Warehouse management and other functions. Bluetooth module can also be used to realize storage management and data reporting. (4) A high security access control and storage environment data collection algorithm is studied. The algorithm is based on MD5 encryption and dynamic cryptography, which improves the security and management convenience of the access control system. At the same time, using contact sensing technology, can automatically realize the storage data, environmental data collection and reporting function. (5) realize the design and development of the data collection platform in the opportunistic mobile sensor network. The hardware design and bottom control algorithm of wireless sensor network nodes, UHF RFID reader and access control system Bluetooth control board are designed in this paper. The customization and development of the special software for the mobile phone is completed, and the design and implementation of the function modules such as the data storage in the server side, the Web query management and so on are completed.
