Research Of Moving Target Location Based On EnOcean Technology

Using wireless technology to locate moving targets is one of the focus at home and abroad. Based on the analysis of the universal wireless location algorithm and wireless location solutions,This paper studies the basic characteristics of short-range wireless wireless location,especially focuses on the EnOcean technology-based location methods.EnOcean technology in energy harvesting, low power consumption and to avoid packet collision mechanism has superior characteristics, the paper uses EnOcean wireless signal as the location signal, the discussion in estimates EnOcean RSSI signal value at host computer,proposes moving targeting location architecture based on EnOcean technology, designing and completing the hardware to the location structure and test the position of a moving target.For this,mainly discusse the structure of EnOcean technology,energy harvesting and wireless technology. Based on EnOcean ultra-low power consumption, highlighting the advantages of applying it for the current research focus-wireless sensor networking.Based on EnOcean products in unique,using PTM module as a moving target node saves a lot of system development time.According to the communication mechanism between the gateway node and anchor node, focuses on the TCM120 in the "interactive modem"feature and serial transmission characteristics.TCM120 chip designed to use as main chip in nodes, STC12C5A60S for the auxiliary control module, complete the basic functions of a node configuration. Paper made the following aspects of the results:1. Proposed based on EnOcean wireless location technology architectureThrough the analysis of wireless applications and research needs, using EnOcean this new transmission technology as the transport protocol between nodes. Analysis and comparison of several popular current architecture and the use of wireless location positioning algorithm,design wireless location technology architecture based on EnOcean. 2.Designed and implemented the system nodes and the basic location function of the systemFor the current status of short-range wireless positioning systems,extensive research on the market a variety of wireless location technology. Although the research found that existing products can achieve the performance requirements, but due to the conflict between accuracy and cost,it is difficult to meet the general application of the products, therefore,after the study found EnOcean technology in power, transport, cost and other aspects of the unique Characteristics,selecte the system chips can be used as location system ,designe the RF module board for wireless location,hardware design can meet the basic functions of the wireless location system nodes.
