Integrated color ultrasonic control panel and implementation method thereof

Abstract

The invention discloses an integrated color ultrasonic control panel and an implementation method thereof. The color ultrasonic control panel completes all the operations of a color ultrasonic human-computer interface by a single-chip microprocessor, and integrally manages scanning of 8-segment STC, a press key and an encoder; and after the control panel receives a signal of a mouse, the signal is forwarded after converting the baud rate of the signal, a corresponding pulse-width signal is sent to control a press key backlight, signals of the previous various modules are processed and then the processed signals and different header indicators are sent to a host computer in a serial-port way. The integrated color ultrasonic control panel and an implementation method thereof provided by the invention have the advantages of reducing various passive devices, simplifying circuit structure of the whole control panel, low cost and little power consumption, and very few connecting lines connected with the host computer; and the control panel can be connected with the host computer only by a four-core serial-port data line, thus greatly improving transmission rate between the color ultrasonic control panel and the host computer.

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...

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
