The Design And Implementation Of Real-time Control System For Ship Radar Based On Android

With the accumulation and development of mobile Internet technology,a variety of smart mobile devices continue to emerge.The relationship between traditional industries and mobile Internet is getting closer.Using a variety of mobile software and intelligent networks we can easily handle our lives and work,to our production and life has brought great convenience.The impact of mobile technology is bound to affect the traditional shipbuilding industry.with the continuous improvement of network and hardware equipment performance,the traditional ship industry toward a more convenient and efficient direction of rapid development.The traditional ship control system has many shortcomings,such as large volume,high cost and difficult to maintain.To solve the problems of traditional display systems,conform to the development of the times,this paper presents a real-time control system for ship radar based on Android.First,according to the characteristics of the platform and functional requirements,through the use of reasonable methods to achieve the basic functions of the traditional control system,secondly,the key problems of image leakage and target fast orientation in the system are studied deeply,finally,the inherent function of the intelligent mobile platform is used to extend the system function.This thesis focuses on the above contents mainly carried out the following work:1.Studied the development of the ship industry,analyzed the function of ship real-time display control system,introduced the theoretical basis needed to demonstrate the development of the control system,and described the problems and solutions that arise during the implementation process.On this basis,the design scheme of ship radar real-time display and control system based on Android is put forward.2.The system through a reasonable optimization program achieved the basic radar functions in the Android platform and expanded.The interface display uses a reasonable drawing strategy and algorithm to make the display better and smooth and friendly.In order to meet the multi-screen expansion of the functional requirements,the IP multicast transmission mechanism is introduced.The system defined a corresponding multicast address and the corresponding data structure,through the network programming to achieve the corresponding function.In addition,relying on the interactive features of mobile devices,introduced the user management and information management functions,the system functions were extended.3.Studied the key problems in the process of system realization,Such as image leakage,fast target orientation.In view of the above problems,put forward the corresponding solution.For the image leakage point,a method of image replenishment based on quaternion table is proposed,using less memory space to achieve the image completion,solve the OOM problem of the Android system,enhanced image display.On the issue of rapid direction finding,a rapid method of target based on auxiliary angle conversion is proposed.By optimizing the search feature function in algorithm,compress the search range,Reduce target direction estimation time.Finally,the validity of the software design and implementation are verified by testing.The new system is convenient,flexible,real-time,is the traditional ship industry and the Internet mobile industry combined results.
