Public Environmental Paramenters Monitoring System In Passenger Ship Based On ZigBee Wireless Sensor Network

Nowadays,wireless sensor technology plays a great role in environmental monitoring,smart home,intelligent transportation and smart city,but the application of wireless sensor technology is still belong the primary stage in the ship.Therefore,the combination of wireless sensor technology and the ship field will be an important direction in the research of ship automation.In this paper,a model of the Yangtze River channel is selected as the parent ship,analysis of the public space of the cruise ship,the use of ZigBee sensor technology wireless acquisition of public area of the cruise ship environmental information.Through the analysis of ZigBee network topology,combined with the cruise environment,proposed RS232 and ZigBee combined with Wi Fi and ZigBee,taking into account the full wireless structure eliminates the need for a large number of tedious wiring and maintenance work,and also can be replaced at random monitoring area,so the whole system uses the ZigBee and the combination of cruise ship Wi Fi transmission mode,under laboratory conditions,the experimental platform was built and the stability and accuracy of the whole system was analyzed by Lab VIEW virtual simulation software.Firstly,according to the characteristics of the cruise ship navigation environment,selected combustible gas,human infrared,light intensity,temperature,humidity and other sensor components.According to the characteristics of each sensor to design the peripheral circuit,the main controller CC2530 and various sensor set to become the terminal acquisition node,then through IAR software programming to achieve the collection function.In order to improve the accuracy of data transmission,the ZigBee coordinator data protocol format is developed,which can be read in time and accurately by four times.Secondly,the system uses the HLK-RM04 module to achieve the function of ZigBee to Wi Fi,the information received by the ZigBee coordinator is relayed to the ship's wireless LAN environment via the module,the host computer monitoring interface by typing the correct IP address and port number can be real-time view of the cruise ship monitoring area of environmental information.If there is an abnormal situation occurs,the system will send alarm signal to remind.Finally,in the upper computer,the data storage program is written in Lab VIEW virtualsimulation software,write data to read format to achieve the correct reading of the data,which is connect to the access database by means of a link.The sub region is the real-time monitoring of the public environmental data of the cruise ship to facilitate the management of the cruise ship.Finally,through continuous debugging operation,realizes the collection,transmission,information display and data storage function.
