Fire Monitoring System For Large Logistics Buildings Based On Zigbee

In recent years,with the development of social economy,the logistics and transportation industry runs through the entire online shopping,online transaction and other new transaction industries,thus becoming an important support for social and economic development.The logistics building is the key transfer station in the entire logistics transportation process.Due to its large space and complex results,once a fire accident occurs,it is likely to cause major personnel and property losses.Research and design of ZigBee-based large-scale logistics building fire monitoring system is extremely important to ensure the fire safety of logistics buildings.Aiming at the environmental characteristics of large logistics buildings,this paper uses the wireless sensor network established by ZigBee to achieve global coverage and real-time monitoring of the monitored environment.The collection node and coordination node with CC2530 as the core collect,process and transmit the monitored environmental information in real time.The STM32 chip converts the network data transmission format for the main control center module,and at the same time further processes the information transmitted by the collection node and displays it on the center console,and remotely forwards the data to the control terminal through the 4G wireless communication module to achieve real-time monitoring of environmental information Monitoring and transmission functions.This paper builds a BP neural network algorithm model in the host computer,analyzes and processes the environmental data transmitted by the collection node to predict the trend of fire occurrence,and displays the information results through the interface to realize human-computer interaction and fire prediction functions.This design completed the construction of system hardware modules and algorithm models,the establishment of wireless sensor networks,the application of sensor technology,and the software design of coordinator,host computer and acquisition node.Through experiments,the system can effectively realize the monitoring of the monitored environmental information and the predictive function of fire occurrence.The wireless fire monitoring system designed in this paper for large logistics buildings has the advantages of low cost,low power consumption,small size,convenient installation,and high reliability.It is not only suitable for logistics buildings,but also widely applicable to all large-scale fire monitoring and alarm requirements.Construction site.
