Design Of Ultra High-Definition KVM Matrix Control System Based On GoAhead

The development of information technology has driven the development of the Internet industry,the development of RFID,QR code,EPC system,sensor technology,wireless sensor network has promoted the development of the Internet of things,more and more data are produced,collection,analysis,transmission.The fact,we have already begun to enter into the era of big data.In the era of big data in the process of data has been applied to all walks of life,become a very important factor of production,and data transmission,especially UHD?HDMI image data transmission is facing great difficulties.In this thesis,research projects is mainly to development an UHD KVM matrix control system,focusing on HD,UHD data transmission control.UHD KVM matrix as a key signal control equipment,Mainly used in some complex application scenarios,such as a variety of signal sources,display terminal different and so on.The main target of this project is use the different signals as input to the matrix control system,Output to different terminals,this thesis especially for KVM signal transmission remote control.It has been applied in the field of military and security,and plans to expand to the field of film and television late production,transportation,video conferencing and other fields,can foresee the future will play a major role in the field of Internet of things.The research work mainly from Dongguan QiDing Technology Co.Ltd."Ultra HD KVM matrix control system" project,,this system is developed by GoAhead3.6.3,GoAhead is an open source embedded Web server,you can run on multiple platforms,we chooses Linux as the operation platform,using HTML5 and ASP cJSON,C,and other technology Development.The thesis completed following work: introduced the theoretical background of matrix control system,analyzed the development status of matrix equipment and GoAhead,expounded the related concepts and techniques of matrix control.On the basis of in-depth study of GoAhead system,combined with system business,we done a lot of customization work,The background application,front-end application and interface definition of the system are designed.It includes the management of users,roles,the configuration of permissions,the setting of basic parameters of the matrix,the alias settings of input and output ports,the mapping of input and output channels,and the signal control management.The test results show that,based on the GoAhead embedded WEB server,and a large number of customized development work,it is convenient to realize the visual control management of the matrix system.
