Embodiment Construction

[0022] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0023] like figure 1 , image 3 and Figure 4 As shown, the control module of the control system of the operation panel of the Doppler ultrasonic imaging equipment of the present invention detects the actions of the buttons on the operation panel, the TGC potentiometer, the encoder and the standard keyboard. When it is detected that a button is pressed, the control module generates an interrupt for sending the button code. If the transmission line is in an idle state, it responds to the interrupt for sending the button code and sends the button code to the upper computer; if the sending bus is busy, it waits until the transmission line is in In the idle state, in response to the interrupt of sending the key code, send the key code to the upper computer. When the movement of the TGC slider potentiometer is detected or the control module receives an instr...

Abstract

The invention discloses an operation panel control system of Doppler ultrasonic imaging equipment, comprising a control module, wherein the control module is used for detecting an input signal of an operation panel in a parallel way and sending a code corresponding to the input signal to an upper computer during the leisure of a transmission line. The operation panel control system of the Doppler ultrasonic imaging equipment detects input signals of various input devices of the operation panel of the Doppler ultrasonic imaging equipment in the parallel way, thereby reducing the response time and enhancing the operation and control sensitivity of the operation panel.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging equipment, in particular to an operation panel control system for Doppler ultrasonic imaging equipment. Background technique [0002] The operation panel is the human-machine interface of the ultrasound imaging system, generally including ultrasound function buttons, encoder (Encoder, adjustable gain or select the menu of the touch screen), slider potentiometer for adjusting TGC (Time Gain Compensation, Time Gain Compensation), operation Panel backlight, general alphanumeric keys (Alphanumberic Key), trackball. Usually the operation panel uses a single-chip microcomputer (MCU), or a single-chip microcomputer plus a programmable logic device (CPLD) to realize the communication between the operation panel and the host computer, and the general-purpose alphanumeric keys and ultrasonic function keys are independent of each other, and the general-purpose character keys do not exist. Happeni...
