Design Of Intelligent Irrigation System Based On Zigbee Technology

With the rapid development of electronic information technology,many of the techniques combined with other industry,greatly promoted the development and production efficiency,makes the equipment more intelligent,automated and informative,improves the production efficiency and reduce the manpower cost.In terms of automatic irrigation,is to realize the transition from the traditional human irrigation gradually to the intelligent irrigation system based on wireless communication network.However,most of the irrigation system,can only implement simple switch function on the current market,can't show cumulative flow,does not wireless control function and power consumption is larger.In this paper,design of intelligent irrigation system based on ZigBee technology to satisfy the current market to a certain extent of the intelligent irrigation system.System used the hall flow sensor measuring instantaneous flow rate and volume in real-time.System utilizes the mature ZigBee wireless communication mode to transfer information between terminals and the coordinator,theoretically a coordinator can support 65535 terminal node,the coordinator and terminal nodes constitute a small wireless sensor network,sensor data can be real-time monitoring of each terminal,the whole system work in 2.4G ISM unauthorized frequency band,whoever use frequency bands for free.System employ electric valve to adjust the water flow speed,relative to the solenoid valve,it can adjust opening Angle of the valve to precisely control the flow velocity.Systems exploits digital temperature sensor DS18B20 to realize water temperature measurement.In addition,in order to image visual display terminal flow velocity,temperature sensor data as well as he terminal velocity of the flow of control,the system has four terminal node information display of upper machine based on MFC.This paper completed the scheme of intelligent irrigation system based on ZigBee technology,finish CC2530 software and hardware design,the writing of the upper machine debugging,and the alignment between those above a few tests.This solution is relative to the current irrigation systems in the market,the main advantage is embodied in the following several aspects: the accurate control of flow velocity,on computer remote control monitoring,achieving the water temperature measurement,etc.the whole system has low power consumption,high precision,and easy to use,easy to maintain,etc.it Basicly can meet the demand of the current complex irrigation industry.In recent years,there has been a new wireless communication development,therefore aimed at LORA wireless communication mode used in recent years more and more.The end of this article introduced a irrigation system based on LORA wireless communication mode,that the communication distance is relative to the ZigBee is much more,no obstacle of ZigBee test communicate distance is about 75 meters,and LORA transmitted power in 11 dBm(maximum 20 dBm),communicate distance of the actual test up to 200 meters,which has a big advantage in some applications.
