The technical problem blocked or postpone.
The technical solution of the present invention is：
A kind of C-arm x-ray machine wireless data high speed transmission method, comprises the following steps：
1) to C-arm x-ray machine, the image data producing and control data are packaged respectively, wherein：Every frame image number
According to being packaged into some image data bags, every group of control data is packaged into 1 control data bag；
2) image data bag sends in order, and the timing of control data bag sends, when wireless transmission unit receives control data
So as to be inserted into the head of current image data packet queue during bag, preferential transmission；
3), when radio receiving unit receives packet, judge that this data is image data bag or control data bag, in this way
Control data bag then priority treatment, in this way image data bag then normally show.
Above-mentioned control data bag sends 1 time for every 1 second, and each control data bag size is 10 bytes.
Above-mentioned every two field picture is divided into 2098 packets, and each image data bag size is 1000 bytes.
Image data bag and control data bag are with the transmission of TCP/IP mode.
The present invention also provides a kind of C-arm x-ray machine of achievable image data wireless high-speed transmission, and its special feature exists

Including image control system and image processing system；
Above-mentioned image control system includes control unit, image-generating unit and wireless transmission unit；
Above-mentioned control unit is used for for every frame image data of image-generating unit being packaged into some image data bags, will control single
Every group of control data of unit is packaged into 1 control data bag；
Above-mentioned wireless transmission unit sends image data bag in order, and timing sends control data bag, and will receive control
The head that packet is inserted into current image data packet queue preferentially sends；
Above-mentioned graphics processing unit includes radio receiving unit, graphics processing unit, data processing display unit data
Process response unit；
Above-mentioned radio receiving unit judges that the packet receiving from wireless transmission unit is image data bag or controls number
According to bag, and control data bag is preferentially sent into data processing response unit, image data bag is normally sent into data processing and shows
Unit.
Advantages of the present invention：
1st, the inventive method adopts the preferential Wireless Data Transmission mode of control information, preferentially sends control data, preferentially
Process control data it is achieved that C-arm x-ray machine 200M per second position data be wirelessly transferred speed, reached X ray image
High-resolution real-time radio transmits.
2nd, the inventive method with the transmission control data of TCP/IP mode and image data it is ensured that the reliability of data transfer
Property.
3rd, the control data of the inventive method is that timing sends, and sends 1 time within every 1 second, data volume is little, is almost not take up wireless
Bandwidth resources.
