The Development Of Jujube Growing Environmental Monitoring System Based On Thewireless Sensor Networks And LabVIEW

Jujube is the dominant characteristic of fruits in Binzhou City, and Real-time monitoringof the growth of its environmental information is extremely necessary. All the time, monitoringthe growth environment information were mostly through artificial timing to acquisition, it notonly bring heavy burden to farmer,real-time and accuracy and the lack of environmentalinformation. In view of this situation, based on the environmental information acquisition part,environmental information monitoring system for environmental information processing part isdesigned by using the virtual instrument and using the technology of wireless sensor networks.Through this design, make jujube growth environment monitoring information more automatin,thus reducing the farmers labor burden.Environmental information acquisition part based on the analysis of the jujube growthenvironment monitoring application environment, and for considering the hardware andsoftware research and development costs, so that part of the wireless sensor network usingZigbee technology. By comparing the market various types of Zigbee module, the paper usesTI’s CC2530as the core of the module design, and the use of TI’s Z-stack protocol stack forenvironmental information collection part of the design. On the coordinator node environmentinformation collection part, routing node and sensor node application design ideas, workflow,and serial communication protocol for the study design. In order to reduce outside interferenceand facilitate the application of environmental information collected, each node sensor mostlyusing digital sensors. Sensor nodes will be collected environmental information to be uploadedto the multi-hop fashion coordinator node, then the coordinator node environment informationtransmitted via the serial port to display environmental information processing section storage.Environmental information processing section compares the advantages anddisadvantages of the hardware and virtual instrument after instrument, from a functionalexpansion and economic aspects into account, such as the use of virtual instruments (ieman-machine interface). By comparing a variety of programming software, the paper uses Nl’sLabview software for environmental information processing section (ie, the PC program)design. Short development cycle, multi-threaded parallel running LabVIEW and modular is theadvantage lies. Run the program from considerations of efficiency, this structure has beenstudied to improve the process, to arrive at the program structure of the system compliance.Thedevelopment of environmental information monitoring software to get real-time data withnodes from the coordinator, real-time display, record storage, GPS positioning and other functions, users can easily jujube on growth management. Virtual Instrument stressed that"software is the instrument", so it has incomparable advantages instrument hardwaremaintenance and upgrades.The experimental results show that the indicators system design of the initial designrequirements. Environmental information acquisition part of the design is simple and reliable,flexible networking, but in terms of transmission distance and time are not good, need tofurther improve. Characteristics of environmental information processing part is stable, reliable,friendly operation interface.
