Design And Implementation Of Heilongjiang Bayi Agricultural University Campus Landscape Control System

The design according to staff and students needs to do a timing open and closed forthe Heilongjiang Bayi Agricultural University’s campus rockery waterfall, collect and displaythe real time meteorological conditions, storage and export the real timemeteorological conditions at the same time. The design adds the median according to the packetloss in wireless network communication. The design use the PLC and Delphi as the core, andthe design transmit the signal with the wireless bridge. This system can collect the real-timedata which is in the scene and control the equipment which is in the scene, and the systemwhich has the flexible function has the strong communication ability.The system with sensor to achieve the collection and storage of environmental parametersuse the FX2N type PLC which is the controller in the slave computer and Samkoon touchscreen which is human-computer interaction interface in the field as the core.The slavecomputer can switch the manual control and automatic control to controlling the pump openedand closed, but the slave computer need someone choose between Manual control withautomatic control. The hose computer system with the development of Delphi which canstorage and analysis of data has the function remote controlling pump start and stop. At thesame time, this paper introduces the communication protocol between slave computer and hostcomputer, stability analysis of system components. The design adds data compensation forlosing data packet when the system uses wireless communication. The data corrects by addingmedian which can effective modify the error.The system which is tested in the long time has a tremendous characteristic which isstability, simply operable, easy to preventive and so on.
