The Design And Implementation Of Reprogramming Data Acquisition System Based On Deluge

Wireless Sensor Network (WSN) is consists of many micro sensor nodes which are deployed in monitoring area.These nodes form the multi-hop self-organization network by wireless communication. WSN combines the computer technology, wireless communication technology and sensor technology together.And it is broadly used in many civilian application areas, including environment monitoring, military field, intelligent argricultue and medical care. Nowadays WSN is one of the most popular research directions.In the data acquisition system, you may need to collect multiple data types, wireless sensor networks that may be consist of a variety of hardware platforms or sensor board, so the establishment of heterogeneous wireless sensor network data acquisition system is necessary. Sensor network deployed for the first time, it may be are mote task allocation, node software updates or network functions configuration, but the monitoring area there may be dangerous or sensor network nodes and the large number of factors can not be recycled all the sensor nodes, so the use of traditional cableload the image, you must use the wireless distribution and load system code image dataway, that is to say, the system must have reprogramming function. In addition, in heterogeneous wireless sensor networks, the system image must be able to distinguish between different hardware platforms and to distribute the load to the corresponding sensor node.The article achieves a distinction between hardware platforms Deluge protocol, re-programming capabilities of the wireless sensor network data acquisition system.The article first analyzes the domestic and international wireless sensor networks, in particular, applications and research status of the data acquisition system, and then briefly describes the common wireless sensor network operating system and re-programming techniques, Went on to describe the data acquisition system requirements, functional requirements, performance requirements and operating environment requirements, followed by the design of the data acquisition system architecture, and design and implementation of the various functional modules of the system, including the node information module, perception data module, control command module and re-programming features four modules, and finally set up the test environment, the various fumctional modules of the system test, and test system data packet loss rate and robustness, performance, results show that the data acquisition system has a measurement accuracy robustness, etc., to meet the needs of users to efficiently collect data and re-programming system.
