The Design Of Wireless Sensor Network For Warehouse Environmental Monitoring

In recent years,the development of wireless sensor network (WSN) technology isvery rapid, and related technology also comes into being. The zigbee protocol standardsspecified by zigbee alliance is the first choice for many companies or university toresearch.The purpose of this paper is to design a collection-aware information systems inthe drug storage room environment,the research of this topic is studied from thefollowing aspects：The zigbee knowledge is introduced at first,and we analyse the current status ofthe application of wireless sensor networks,elabrate the meaning and significance of thisresearch project.Combined with the actual project requirements and system index, thedesign scheme of the wireless monitoring network is put forward. The monitoringnetwork need to accomplish the monitoring of security and drugs’ quality.The networkmust be robustness and have a steady and reliable communication transportation.Thehardware on the the aggregation node of the acoordinator in the wireless monitoringnetwork is designed, including the circuit schematic diagram and the pcb layout.Network monitoring system software is designed,including the establishment of thenetwork, the aggregation and transport of the information.During the actualdesign,dormancy mechanism is adopted to reduce the power consuming.and hostcomputer program is design to show all the perception information on the PC.After completing hardware and software design, we debug a single coordinatoraggregation node including the debugging of the matching circuit and the testing oftransmiting power. By testing the actual results of power,it shows that the results meetthe requirements. For a different number of nodes in the network, a communicationreliability testing is carried out.At last,by host computer program, we complete theinformation collection test of the entire monitoring system. The test results show thatthe network monitoring system are capable of collecting sensory information stably,achieving the monitoring of storage equipment.
