The invention provides an ultrasonic flowmeter, which includes a central processing unit, a peripheral circuit, a digital signal processing unit, a display drive circuit, a liquid crystal display and an input device, and the digital signal processing unit includes a GUI processing subunit, an instruction storage Subunit, instruction acquisition subunit, wherein: the GUI processing subunit is used to display a graphical user interface with operation buttons and judge whether the operation button is triggered by scanning the graphical user interface; the instruction acquisition subunit uses When the operation button is triggered, the corresponding operation instruction is executed, so as to load the corresponding function instruction from the instruction storage subunit and send it to the central processing unit for execution. The invention also provides a corresponding method. The invention realizes the function command input through the independent digital signal processing unit and the graphic user interface, and greatly facilitates the use of the ultrasonic flowmeter compared with the traditional command line interface input mode.
Description
technical field [0001] The invention relates to a flow detection device, more specifically, to an ultrasonic flow meter and a data processing method. Background technique [0002] Ultrasonic flow meters are instruments used to measure liquid flow, and are currently widely used in petroleum, chemical, metallurgy, electric power, water supply and drainage and other fields. [0003] Such as figure 1 As shown, the traditional ultrasonic flowmeter includes a 4*4 keyboard, a central processing unit, and a dot-matrix display (such as a 160*32 dot-matrix screen), wherein the central processing unit can only receive digital commands such as 0 to 9 ; While the display uses a dot matrix display, more than 10 signal lines are required, and the lines are complicated. And the dot matrix display can only display simple character data. [0004] Since the above-mentioned ultrasonic flowmeter uses a 4*4 keyboard, it can only input digital commands of 0-9. The ultrasonic flowmeter has more...
