ABSTRACT
Wireless sensor networks system compare with the traditional wired sensor networks, with less cost, easy to install, low maintenance and updating of the cost advantages, Very suitable for the region where difficult of wire, staff hard to arrive and some inaccessible places on the provisional status of the remote monitoring. Against the features of the dangerous goods storage system, the desigen used new generation of automatic data collection technology-WSNs.It designed and implemented a wireless sensor network nodes by the use of ATmega 16 MCU and a RF chip nRF905,throug the wireless communication transmission to a remote cluster node and host computer communication. To achieve the temperature data acquisition monitoring, Enhanced security monitoring and real-time, remote monitoring and control network
First of all, it analysis the monitoring features of the current warehouse supervision’s features and the development of WSNs, gives the significance of this design, the main work of this design and many other basic information like this. It designs an overall framework of WSNs nodes and has the relevant technical analysis and rational choice according to the framework. And then, gives the overall design of the wireless sensor network node, makes a choice of the core device as well as the hardware and the software circuit design. It links and adjusts the system, and does many other related works, and list many solutions to many specific problems in the typical Commissioning. Finally, sums up this design and gives the proposed of the further study and design.
The realized network has the advantages of low implementation cost and small scale. Tests results indicate that the temperature information is correctly collected after the network works. The network can be applied in fields such as storage environment control and monitoring.
