The Experts Port For Remote Monitoring System Of Crop Growth

Judging crop production according to crop image is an important method in agricultural research.Crop growth remote monitoring system can effectively improve the efficiency of agricultural experts or managers image acquisition.Operators move remote site acquisition equipment to take pictures and other operations through the expert port.At the same time,the captured image information will be sent to the management center or expert port.Experts or managers can sit in the office according to the image information to make analysis of crop growth,watering fertilization decision-making and pest diagnosis.Guide the local staff to carry out the corresponding operations.This article deals with the design and implementation of expert port,which mainly includes:(1)System Requirements Analysis and Overall Design: According to the overall structure of the system,based on the overall function of the system needs to be based on the expert port subsystem requirements analysis.According to the needs to be achieved,the functional modules and software structure design,and planning to achieve the program.Expert port is divided into user module and image acquisition module,Wherein the user module implementation function includes the registration and registration of the user information,The location of the user needs to monitor and so on;The device control module includes control of the stepper motor and the PTZ.(2)Design and Implementation of User Module: The image acquisition module includes remote control of the stepper motor and remote control of the PTZ lens.Create a Windows Form application to achieve the interface design and development.According to the software to achieve the function of the database needs analysis and draw an E-R chart.According to the different examples of the properties and characteristics,establish information tables.Choose SQL SERVER 2012 as a database management system,and use ADO database access technology to access the database.(3)Design and Implementation of Image Acquisition Module: The image acquisition module includes remote control of the stepper motor and remote control of the PTZ lens.In the control of the stepper motor,host the stepper motor equipment to the Yeelink networking platform and deploy the sensor.Design the direction of the sensor switch in the direction of the movement of the stepper motor.The Yeelink platform provides the Web API and send Http request to complete the control of the sensor switch state,in order to achieve the stepper motor remote control.In the control of the camera and the PTZ process,Use the camera to provide the SDK development kit for secondary development.Call the API provided in the SDK to complete the video transmission and so on.Prepared the client and mobile(Android)operating software,So that the operator can remotely control the camera to take pictures,video and so on.The software part of this paper is combined with the hardware part designed by other personnel of the research group to form the expert port subsystem in this system.The realization of the system allows the operator to use the software for remote acquisition of images to enhance the efficiency of agricultural research.
