Application And Research Of Dynamic Configurable WSN Universal Measure And Control System

Wireless Sensor Networks (WSN) integrates sensor technology, communication and computer technology to unify data collection, transmission and processing, it has been widely used in various industries, the application and research on the measure and control system is also becoming a hotspot. At present institutes are researching the measure and control system which based on WSN separately, as a result, a lot of repeated work on development has been done. For this reason, this paper puts forward a design of dynamic configurable WSN universal measure and control system (DWSNS). The aim is to provide a basic frame of universal measure and control system which based on the WSN, on which hardware can be trimmed and software can be customized so as to reduce duplication of work and improve reusability and development efficiency.The main work and innovation of this paper are as follows:(1) Provide a universal software and hardware model of DWSNS in the analysis of general structure of measurement and control system.(2) Provide a design of universal hardware platform of DWSNS according to the design theory of hardware component. MC13213 from Freescale company is chosen as the main control chip, analog and switch input/output modules are designed as separate modules and not connected with the specific pin of the main control chip. This method makes the hardware functions of measuring and controlling nodes not cured and improve the flexibility and versatility of the hardware.(3) According to the theories of configuration software and software component, the designs of upper and lower computer software are finished. The design of lower computer software based on the idea of embedded database , that is, to store configuration parameters into embedded database in accordance to certain data structure and give relevant flash address location algorithm, the lower computer can search for corresponding configuration file in the embedded database according to the algorithm and then analyze and perform corresponding operation in the way of configuration file so that the general function of lower computer can be changed to dedicated function.(4) On the design of upper computer software, this paper provides configuration software with good user interface and detailed design is made for its database. User can Application and Research of Dynamic Configurable WSN Universal Measure and Control System Abstract make configurations easily to the universal hardware platform of DWSNS through configuration software. In addition, this paper also provides the design of monitoring software, the software can generate monitoring interface for specific system on the basis of XML file generated by configuration software so that the monitoring of each measuring and controlling node in WSN is achieved.(5) In order to test and verify the feasibility and reliability of DWSNS, in the last part of this paper actual application examples developed under DWSNS are provided.
