The Design Of Automatic Sprinkler Controller Based On Wireless Sensing Technology

Although our country is rich in water resources,Agricultural water consumption accounts for large part of the total.Utilization of water resources is not reasonable and scientific and cause a lot of waste.In view of this situation,changing the way of irrigation is the key.Traditional irrigation mode mainly depends on the experience and observation of manual operation,for the crop water demands judgment is not accurate enough, and its content is too large or inadequate, resulting in the waste of water resources, reducing the utilization rate of water resources, and then affecting the crop growth.In view of the traditional irrigation methods on water use is not high, in this paper, on the basis of consulting a large number of data, puts forward a way of automatic sprinkler irrigation to replace the traditional irrigation mode of flood irrigation and to realize the purpose of saving water.According to wired sensor deployment is not conducive to the ground operations and the problem of high cost.Wireless sensor technology is adopted in this project on soil moisture monitoring, collecting water information, analyzing the data and compared with preset upper and lower limit to control the irrigation equipment start-stop. This design research contents:(1) According to the requirements of the subject and relevant information on the basis of this topic,the whole scheme is proposed.(2) To complete the selection of experimental equipment needed and wireless sensor technology to design and debug the software and hardware.(3) Choose VS2012 development of PC software to complete the upper machine data display and the manual and automatic control.(4) Set upper and lower limits of humidity,and test under laboratory conditions,then make up for the shortfall according to the experimental results.Through the design of experiment,we got the following conclusions:(1) using wireless sensor technology,we can eliminate the erection line costs,and share cost and does not affect ground operations.(2) The experimental results show that the system can accurately collect the data and control irrigation system, and achieve good effect, and basically the design requirements.
