Environment Monitoring System Based On Wireless Sensor Networks For Key Parts Of Hospital

In recent years, wireless sensor network technology has been rapid development, its application field is constantly expanding and deepening, mainly due to the front-end node data in the application of wireless sensor network, real-time collection of multi hop self-organizing network, data store and forward, high dense node deployment, monitoring of regional scale self-regulating, reliable data transmission and other aspects of superior performance, the late the maintenance and expansion of business is transparent to the user, the standard interface is convenient for technical personnel to use. Development of wireless sensor network technology and application is put forward higher requirements for collaborative software development technology and its application, the need for new methods for the development of collaborative software based on hardware platform, so as to ensure the application platform and system of high efficiency, energy saving and stable.The system uses a large number of sensor nodes distribution, through the data of self-organized for centered in the hospital environment real-time monitoring wireless sensor network application platform. Deployed in the hospital environment in a large number of sensor nodes through mutual cooperation of division of labor, can be real-time sensing, monitoring and collection of regional distribution of monitoring object or the surrounding environment information. This system takes the STC89C52RC single chip as the control core design and implementation of 1 terminal and 8 nodes, temperature and humidity, atmospheric pressure, gas concentration, computer terminal can access the sensor nodes collection, and the server system page displays the real time data, the data collected will be kept, analysis and processing operations, each sensor node can carry out wireless transmission and environmental monitoring terminal equipment. In order to ensure the stability, the hospital environment monitoring system based on wireless sensor network robustness and generality of the proposed system architecture, based on the hospital environment real-time monitoring and management system of wireless sensor network hardware platform and software platform and coordination mechanism based on. Finally, research and development of the hospital environment monitoring system based on wireless sensor network and its comprehensive application platform based on practice and application, and has been used and deployed in the first people’s Hospital of Chang shu City successfully.
