An Intelligent Tobacco Warehouse Monitoring System Based On Zigbee Wireless Network

The development of information industry has always been the most important measure for national scientific and technological progress, now, when mentioning IT technology, a new concept will come into our eyes, this concept is the "Internet of Things, by definition, the Internet of Things is a kind of net which connects the material objects, it can connect any item with the internet, exchange information and communicate, in order to achieve intelligent identification of items, location, tracking, monitoring and management. In fact, I think the Internet of Things is not a new concept, but rather the reorganization and integration of the existing IT technology. Through a variety of information sensing device, such as sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners, gas sensors and so on, by collecting the sound, light,heat, electricity, mechanics, chemistry, biology and location information of objects or processes which need to be monitored, connected and interacted real-time, it forms a huge network with the internet. At the present stage, applications in IOT are multi-based on wireless sensor networks, Wireless sensor network (WSN) is deployed in the monitoring area by the large number of low-cost micro sensor nodes which form a multi-hop network of self-organization through wireless communication, which aims at collaborative sensing, collecting and processing the information of perception object in the network coverage area and then sending them to observers. Wireless sensor network in recent years is a relatively new research focus, it has a broad-based application prospects such as military affairs, healthcare, e home, structure health monitoring, complex mechanical control, urban traffic, space exploration, large workshop and warehouse management, and fields like security sensor in large workshop. With the in-depth study and broad-based application, WSN will refer to all areas of human life. There are lots of successful cases on WSN research and application. But I find that most applications only stay in the realization of the positioning, such as electronic tags in logistics applications or environmental monitoring, such as the temperature and humidity monitoring of greenhouse, the monitoring of the mine Gas concentration. This is the basic part of IOT. The essence of IOT is not only able to achieve the interconnection between things and network, but also able to control things through the net. This tobacco warehouse monitoring project aims to achieve a complete warehouse Phosphine, temperature and humidity monitoring and conformity, so that warehouse real-time monitoring can be done by computer。In this project, we carry out the research of wireless network architecture, and finally form the main transmission network architecture based on the802.11standard and Zigbee technology. In the terminal design of the system, we use CC2430to complete the monitoring node. This paper primarily describes the network architecture and hardware implementation of the tobacco warehouse monitoring management system.
