An integrated color ultrasound control panel and its implementation method

Abstract

The invention discloses an integrated color ultrasound control panel and its implementation method. The color ultrasound control panel uses a single-chip processor to complete all operations of the color ultrasound man-machine interface; it centrally manages the scanning of 8-segment STC, the scanning of buttons, and the scanning of encoders. Scanning, after receiving the signal from the mouse, convert the baud rate and then forward it, send the corresponding pulse width signal to control the backlight of the button, process the signal of each module in front, and send it to the host by serial port with different header marks . The integrated color Doppler ultrasound control panel and its implementation method provided by the present invention reduce many passive components, so that the entire control panel circuit has a simple structure, low cost, low power consumption, and there are very few connecting lines with the host, and only one The four-core serial port data line realizes its connection with the host, which greatly improves the transmission rate between the color Doppler ultrasound control panel and the host.

Description

technical field [0001] The invention relates to the field of color ultrasound machines, in particular to an integrated color ultrasound control panel and an implementation method thereof. Background technique [0002] The color ultrasound machine used in the prior art, such as figure 1 As shown, a color ultrasound host 200 and a control panel 100 are included. The connection between the control panel 100 and the color Doppler ultrasound mainframe 200 is realized through 10-20 data cables, and many passive devices are used, and the realized circuit is large in scale and complex in structure. For example, in the 8-section image gain adjustment circuit of its STC module 110, each STC potentiometer will pass through an A / D converter, and the 8-section STC has eight STC potentiometers through eight A / D converters, and then passes through eight A / D converters. The complex programmable logic device CPLD150 is connected to the MCU control panel 170 , and then sends the image segme...

AI Technical Summary

Problems solved by technology

[0003] In this way, the connection between the color ultrasound control panel 100 of the prior art and the color ultrasound mainframe 200 needs to be realized through 10-20 data cables.

Moreover, each component module in the control panel of the prior art adopts many hardware passive devices, and its circuit power consumption is large, and the 8 A / D converters of the STC module must be connected by more control lines, which will also lead to excessive cost , making the entire control panel circuit large in scale and complex in structure
