Embodiment
Fig. 1 is a kind of principle of work block diagram of digital oscilloscope.The principle of work of this digital oscilloscope is such: at first, outside signal input is exported to the A/D modular converter and is carried out analog to digital conversion through analog front-end module, exports to trigger circuit simultaneously, carries out signal triggering.The output of A/D modular converter is connected to FPGA (field programmable gate array), carries out data and handles.Another input end of trigger circuit is comparative level, and trigger circuit output is connected to FPGA, and trigger circuit generally constitute by triggering modulate circuit and comparer, and comparer output is directly connected to FPGA.The judgement that FPGA triggers inside, and control sampling process.FPGA is connected with the control processing module, accepts the control command from the control processing module, data is exported to the control processing module, and show.Control processing module control D/A modular converter is for generation of the needed comparative level of trigger circuit.The control processing module is connected to the output terminal of load module, is used for acceptance from the operational order of oscillograph button and various interface.Though dissimilar digital oscilloscopes there are differences at physical circuit, basic framework is similar.
Based on above-mentioned digital oscilloscope, digital oscilloscope label display control method provided by the present invention comprises following implementation step as shown in Figure 2:
If step 2. is determined the measurement project of being scheduled to, then utilize digital oscilloscope to implement to measure operation.
In each above-mentioned implementation step, critical step is step 4.Below, launch specific description in conjunction with the specific implementation process of the step 4 of Fig. 3.
At first, press Measure (measurement) key of digital oscilloscope, upspring when key and (generally only to produce effect when menu is pressed, function is just arranged when only upspringing) time, Measure key corresponding key message is used for monitoring button specially to digital oscilloscope inside control processing module such as single-chip microcomputer sent.When key was pressed, single-chip microcomputer can send interrupt request, and informed the key information of resolving.This key information is corresponding with concrete function, such as pressing the cycle button, will measure the cycle of current demand signal exactly.State machine receives this press key message, is converted into feature message, and the while sends this feature message to GUI (graphical user interface) unit (this GUI unit is arranged in the control processing module, and is not shown in the figures) in the digital oscilloscope.
Feature message is carried out concrete function on the one hand, offers on the one hand to carry out the GUI unit that draw at the interface.The GUI unit resolves to forms message (being exactly to need the interface what is drawn) with feature message, draws concrete interface according to the corresponding function of the button that sends over.The GUI unit just can obtain to measure number when drawing, what measurement projects are namely arranged.The corresponding relation at function and interface is kept in the static table.This static table is recording the interface portion that each function need refresh, and need search for the necessary information in interface of drawing in the resolving in static table.
The GUI unit will in time carry out corresponding interface and refresh after having obtained feature message.For example when receiving the Measure feature message, judge whether statistical function is opened.If statistical function is not opened, measure an existence but have, then on the interface, only show currency as shown in Figure 4, and do not have little label.Be in open mode if at this moment get access to statistical function, then refresh the statistics forms, for example current function is the statistical function in cycle, and the part that then needs to refresh is respectively grid, statistics part and left menu part.After statistical function is opened, draw the little label that each measures item one by one.At first need to obtain to measure the title of item, after title was determined, the content of label was just definite, then need obtain to measure information source, and after the measurement information source was determined, the color relation of label substance had been determined.So far, small tenon is signed to draw and is finished, and obtains digital oscilloscope display interface as shown in Figure 5.
Above-mentioned label display control method is applied among as shown in Figure 1 the digital oscilloscope, just can makes digital oscilloscope also have the label Presentation Function.This label Presentation Function utilization is added the way of little label and is given prominence to the corresponding measurement item of measurement data on the measurement item, and utilizes the shape of little label to indicate measurement item, color showing measurement information source.Like this, the user does not need to observe the waveform district, directly observes measured zone and just can clear view arrive the statistics of measuring.
More than digital oscilloscope and the control method thereof with label Presentation Function of the present invention had been described in detail.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention it being done all will constitute to infringement of patent right of the present invention, with corresponding legal responsibilities.
