The Design And Implementation Of Crop Growth Image Remote Acquisition Site Based On B/S Framework

Crop growth process often occurs pests and diseases,lack of water and other factors that are not conducive to crop growth,once the occurrence and not timely discovery will have a greater impact on crop growth.And how to timely,efficient and accurate detection of adverse crop growth factors,will undoubtedly become effective control and reduce its key to crop hazards.In this context,based on the B / S architecture,combined with computer vision,remote network,remote control technology,the crop growth image remote acquisition site was designed to achieve the remote control image acquisition equipment in the space horizontal,vertical Move,to more quickly,more efficient and more accurate access to farmland crop growth process images,to achieve long-term monitoring of crop growth requirements.The paper mainly carries on the following work:(1)According to the movement requirements of the image acquisition equipment,by analyzing the running principle and driving mode of the stepping motor,selecting the motor suitable for the site,calling the control program of the stepping motor prepared by C++ through Java JNI,Response to the event,you can remotely control the image acquisition device vertical and horizontal direction up and down left and right movement.It is possible to adjust the step amount of the stepping motor and adjust the pulse period as needed to change the running speed of the image acquisition device.(2)According to the needs of the network in the remote control,the method of setting up the local area network and the IP address of the public network are analyzed,and the static IP address is assigned to the horizontal and vertical motor and the network camera and the ports are assigned On the basis of this,further through the router to establish a virtual server for port mapping,and ultimately the completion of the site server and the formation of remote control network research tasks.(3)According to the image acquisition requirements of data center and expert port in the project of "crop growth remote acquisition automatic monitoring system",the site provides the remote service plan for these two modules and completes the structural design of data message command and control command,Given the specific implementation of the program.The data center according to the need to send orders to the site,the site based on the contents of the command to complete the image acquisition task,back to the data center;expert port and site connection,you can remote real-time control image acquisition equipment to complete the target range of image acquisition,real-time Back to the experts to watch.
