Intelligent Logistics Tracking System Based on Wireless Sensor Network

Wireless sensor networks are widely used to collect and monitor data in the physical world play a vital role. This article mainly studies intelligent logistics tracking system based on wireless network. In this paper, compressed sensing theory is reconstruct environment monitoring cabin verify validity of theory. The five types sensors placed specified position carriage for multi-point sampling, each node performs collection every 45 seconds. paper uses entropy weight fuzzy comprehensive evaluation method evaluate platform planning scheme. network adopts multi-zone networking method, which divides entire coverage area into multiple sub-areas. Each access point responsible controlling sub-area. At same time, will also become mobile terminal backbone actual image transmission, there two transmission modes Zigbee module involved, transparent point-to-point mode. mode, only communication between gateway device edge can be carried out, devices cannot out. order test that actively track status object, temperature whether object at different temperatures. achieve goal performance testing, program was written simulate large number users logging time perform operations system. Starting from 15m, radius increases by 5m 50m, average positioning error gradually decreasing. results show introduction Internet technology greatly improve utilization existing resources.
