Design And Implementation Of Information Monitoring And 3D Visualization System In Irrigation Area Based On WSN

Information monitoring is an important content of improving the level of modern management in irrigation area.The traditional information monitoring in irrigation area presents the following three characteristics: single-point?wired and local,so that it is difficult to realize the information monitoring of the irrigation area.Using modern water conservancy information technology,timely access to real-time water status information of water resources system has become an important support technology in parallel with the development of modern water resources management technology.Against the characteristics :large range?scattered projects?regional climate differences?uneven temporal and spatial distribution of rainfall,this paper is based on the WSN and chooses People's Victory Canal headwork as the typical test scenario to study and realize the data acquisition?data transfer and data processing under the complex climate in the intelligence irrigation area,the specific work is as follows:1.Design and implementation of WSN based on ZigBee protocol: the overall design scheme of WSN is put forward though adopting Zigee SOC solution CC2530 TI launched with combining industry-leading Z-Stack protocol stack.Meanwhile coordinate devices?routers and end nodes are designed and implemented from both aspects in hardware and software against these problems: network topology?network management?multi-source data acquisition interface for data acquisition and control issues etc.2.Design and implementation of intelligent irrigation system based on WSN: according to the complex environment of people's victory Canal irrigated area,and the problems existed in current water-saving reconstruction and Continue Constructing in irrigation district,this paper chooses the representive headwork as the typical test scenario.Here WSN based on Zigbee is applied on information construction in irrigation area to realize the automatic collection and transmission of the soil moisture?ambient temperature and relative humidity? longitude and latitude.In order to solve the problem of sensing the remote real-time transmission of data,STM32F107 is used as the application processor for connecting the wireless sensor network based on ZigBee protocol with the GPRS module based on TCP/IP protocol.And at the same time,?C/OS-? operating system is introduced to manage the processor hardware and software resources,avoid defect before and after program design,and realize the free information exchange between wireless sensor networks and Internet.3.Design and implementation of headwork 3D visualization system based on Unity 3D: fuse the virtual scene and the data that WSN senses innovatively,then use the data to drive virtual scene movement to formate the spatio-temporal information of water resources in irrigation area.First,Max 3D is used to model the headwork gate,the channel,the building?the nearby farmland?number and some other objects in the typical test scene.Model integration and scheduling are achieved through Unity 3D engine to realize the functions including typical scene roaming?sluice gate water measurement?soil moisture visualization and information inquiry etc.The test results show that the monitoring system studied in this paper can provide the good expansibility and can run stably?realize the information sample and transmission successfully.The realized headwork 3D visualization system with the amalgamation of the perception data and virtual scene can display the perception data lively,and provides a new way of the information processing for irrigation area.Meanwhile,the developed on-line monitoring equipment for soil moisture has passed the examination of Henan electronic products inspection institute,the equipment has been applied in the people's Victory Canal administration of Henan province,and its realization plays a role model for the information built of irrigation areas.
