Implementation Of Wireless Ultrasonic Probe For Data Transmission And Data Display System Based On ZYNQ

With the rapid development of Internet technology,mobile devices have become an indispensable tool in human life,the mobile devices’ function is not only in communication,also mobile devices can achieve a variety of functions through the support of apps.Today,there are a lot of apps on mobile phones,the phone has gradually replaced the camera,MP3 and so on.So,machine and other mobile communication are very important for people’s lives.If we can develop related projects with mobile phones,it is in line with today’s development trend,also it can be convenient for people and more close to people’s lives.mobile phone can meet what we need when we develop software projects.So This paper combines traditional medical ultrasound probes with mobile phones,Mobile devices become the terminals displayed in wireless Ultrasonic probe.It can replaces traditional cable probes as medical devices and it is convenient to use for doctors or patients,Greatly simplifies the work of doctors.Combining traditional medical ultrasound probes with mobile phones will bring a substantial breakthrough in the medical industry.In this paper,we will achieve a portable wireless ultrasonic probe,througe the mobile phone software for image observation and sonication,and save the user’s information through the database.This paper is divided into four parts:After collecting the data,transfer the data to DDR memory through the DMA;Build the embedded Linux development environment in the development board,through the wireless transmission,we transfer the data from DDR to the mobile phone,and Set up the receiver for parameters,assign parameters to the register in the development board;Develop android software on the phone to achieve the data processing and image display;Develop an interface for the debugging of ultrasonic parameters on the phone,it is convenient for the doctor or user to debug the probe and establish database to hold patient information.First,we need establish the DMA transmission channel through the Vivado software,create a system.bit for BOOT.bin in the development board,achieve the DMA’s drive program,and transfer the data to DDR memory,Implement the transfer of data in the hardware platformNext,Build the embedded Linux system in the development board,Write and migrate the relevant driver’s programs,Set up the socket server side,Complete the mapping of virtual addresses to DDR memory,and the data in memory are sent to the phone by wireless transmission.To combine the traditional medical ultrasound probes with mobile phones,we needdevelop android software on the phone to receive the data,Complete the ultrasonic data processing module with C++,and Complete the display module of the interface with java.Finally,in order to be convenient for the doctor or the patient to debug the probe and design ultrasonic parameter debugging interface on the phone,achieve the driver of parameters download module.With the same time,we need open source database Litepal to save the patients’ information,and it is convenient for doctor to observe the illness.
