The Design And Realization Of Hospital Speech Calling System Based On Raspberry Pi

With the continuous development of embedded technology,mobile devices with low power consumption and high reliability have been developed rapidly.At the same time,all walks of life face to the innovation and reform of embedded technology.At present,most domestic hospitals also used more common on the market similar to the bank,the government affairs hall calling system,such a system has the versatility and universality,can’t meet the special needs of the business of the hospital;another scheme uses idle computer PC as a display and voice calling processing unit,but this kind of solution caused PC computer idle waste of resources,at the same time,PC computer large volume space.Based on the Raspberry Pi hardware platform,Python technology,EKHO(Chinese aftersound engine),SQL Server database technology and MFC programming technology,realizing the whole process of medical personnel use software to complete the voice calling station.Because the Raspberry Pi volume is only the size of a credit card,running the Linux operating system and hardware platform has rich interface,very suitable for hospital station terminal display and voice call processing unit,can be used as a reference model and examples of each hospital queuing system.The system mainly implements the following functions:(1)LED and Raspberry Pi connected to the TV as a monitor,and setting up the Ekho Chinese speech engine in Raspberry Pi,can be written using Python2.7 and complete the calling terminal interface display and voice call function.(2)through the MFC technology to design and development a complete client software,complete the active function of the station.(3)the interface of the docking with the hospital HIS,LIS,PACS database,access,complete patient information at the same time,combined with the hospital’s volume of business needs,support a client software history data on fast query and query.
