Description

Application method and device for reading value of spectrum analyzer

technical field

The invention relates to spectrum analyzer technology, in particular to a reading value application method and device of the spectrum analyzer.

Background technique

From the relationship with PC (Personal Computer, personal computer), there are generally two types of spectrum analyzers: one is a PC-based instrument, which exists as a special device built in the PC, and the display keyboard of the instrument itself The other is the embedded instrument, which has its own system to realize all its functions (display, keyboard, power supply, etc.). The second way is to use the instrument with PC resources. The instrument needs to be connected to the PC. The PC realizes the operation of the instrument through the transmission of control commands. The implementation method is based on the basic functions of the spectrum analyzer. Programmable instrument standard command set) and VISA (Virtual Instrumentation Software Architecture, virtual instrument architecture) driver as the medium, the application tool software for spectrum analysis with the help of powerful resources of PC, generally called this kind of software as "host computer" (corresponding instrument "lower computer"). Similar technologies are also called virtual instrument technology (the instrument is divided into three parts: data acquisition card hardware, data acquisition card software, and PC-side data processing software). FIG. 1 is a schematic diagram of the application of a PC instrument based on VISA and using SCPI as a carrier in the prior art.

Due to the limitation of instrument cost, general instruments are built on embedded systems, but various applications are limited by embedded system resources (storage space, computing speed, etc.). The above-mentioned method of using PC resources for embedded instruments alleviates this problem.

In the prior art, as an analytical instrument, a spectrum analyzer generally provides a reading function, that is, the function of reading the horizontal and vertical coordinates of the spectrum data. This function is called the Mark function. As the name implies, the Mark is to mark the position on the data , and read the value information showing the location after marking the location. FIG. 2 is a schematic diagram of a display screen of a Mark function provided by a general spectrum analyzer in the prior art.

In the process of realizing the present invention, the inventor found that the above-mentioned prior art has the following deficiencies:

Since the spectrum analyzer is generally an embedded device, it does not support standard keyboards, mice and other peripherals. Even a PC-based spectrum analyzer only supports the mouse and keyboard because of the operating system, and the mouse and keyboard control the instrument. It is not commonly used, so the instrument keyboard (different from the standard PC keyboard) and knobs are generally used to control the instrument, such as the schematic diagram of the instrument keyboard and knobs shown in Figure 3. Therefore, the application of the Mark function is usually controlled by using the instrument keyboard and knobs, which makes the operation of the Mark function application inconvenient and the usability of the instrument is poor.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

As widely used human-computer interaction devices, mice and keyboards are widely used in the PC field. With the promotion of Windows, people are becoming more and more accustomed to using keyboards and mice. The flexibility of the mouse and the richness of the keyboard can be used to better control and use the instrument. The upper computer in the embodiment of the present invention controls and uses the instrument based on the PC, and considers designing a new method of using the instrument on the instrument through the use of PC peripherals (such as mouse click or double-click), so as to realize the instrument quickly and efficiently. The application of the Mark function improves the usability of the instrument.

The application operation of the Mark function generally includes creating a Mark, selecting a Mark, moving a Mark, setting a Mark display property, deleting a Mark, and positioning a Mark, etc. In the above operations, except for creating Mark, other operations are based on selecting Mark, so efficiently solving the selection problem will bring convenience to other operations.

In the embodiment of the present invention, the implementation of selecting a Mark can be achieved by selecting a specified Mark through an index, and establishing an index table for the created Mark, and selecting an index in the index table means selecting the Mark corresponding to the index, for example, using an index to select a Mark as shown in Figure 4 The schematic diagram of the spectrum analyzer display screen is shown.

Based on the index table, you can easily find the Mark corresponding to the index, but you need to know what the index is. How can you intuitively find the required Mark without knowing the index? It is considered in the embodiment of the present invention that the mouse is an effective spatial positioning tool, through which the objects within the range of motion displayed by the mouse can be positioned according to the vision and the mechanical movement of the mouse, based on which the Mark can be selected by clicking the mouse, For example, as shown in FIG. 5 , the schematic diagram of the spectrum analyzer display screen where Mark is selected by clicking the mouse is shown.

The circle in Figure 5 is the mouse. At this time, the mouse needs to be aimed at the Mark and click to select the Mark. Since the Mark is a more accurate point mark, when the signal changes frequently, the Mark will also frequently lock the signal (change with the signal) In this case, it is more difficult to aim the Mark with the mouse. In order to alleviate this problem, in the embodiment of the present invention, it is considered to enlarge the Mark selectable area, that is, to enlarge the coordinate value area of the mouse click on which the Mark can be selected, so as to be easily targeted by the mouse. However, this mitigation solution is applicable to the situation where the signal variation range is not large, and it is difficult to implement the solution when the signal variation range is large (for example, it is impossible to enlarge the area selected by the Mark mouse too much).

After analysis, the embodiment of the present invention provides the following reading value (Mark) application method of the spectrum analyzer, as shown in Figure 6, which may include:

Step 601, obtaining the coordinate value of the mouse click on the display screen of the spectrum analyzer;

Step 602, acquiring the coordinate value of the reading value created on the display screen;

Step 603, calculating the offset value between the coordinate value of the mouse click and the coordinate value of the created reading value;

Step 604: Set the created reading value corresponding to the minimum offset value as a selected state.

As can be known from the processing flow shown in Figure 6, by obtaining the coordinate value of the mouse click on the display screen of the spectrum analyzer; getting the coordinate value of the reading value created on the display screen; calculating the coordinate value of the mouse click and the created The offset value between the coordinate values of the reading value; the created reading value corresponding to the minimum offset value is set to the selected state, and the spectrum analyzer reading function can be realized based on the peripheral mouse of the PC, which is fast and efficient Efficient, greatly improving the usability of the spectrum analyzer.

In the processing flow shown in Figure 6, by combining the coordinate value of the mouse click with the coordinate value of the created reading value to determine the selected reading value, not only can the required Mark be found intuitively without knowing the index, but also You can precisely select the desired Mark.

Based on the way of selecting Mark in the processing flow shown in FIG. 6 , the user clicks the mouse in a larger area, and the action of selecting Mark can be automatically completed by the processing flow shown in FIG. 6 .

FIG. 7 is a schematic diagram of a spectrum analyzer display screen of a specific example of Mark being selected. In Figure 7, the circle marks the current mouse click position (you can define that double-clicking is valid), and the rectangular box is the target Mark (to select the Mark). After the mouse is clicked, the coordinate value of the mouse click position is obtained, and the coordinates of the created Mark are obtained. value, calculate the offset value between all Mark and the coordinate value of the mouse click position (here only calculate the arrow line shown in Figure 7), after comparison, it is found that the offset value of the coordinate value of the Mark of the rectangular box is the smallest (the coordinate value of The difference is the smallest), then set the Mark to the selected state.

That is, the above-mentioned way of selecting Mark is: click the mouse near the Mark (can be defined as double-clicking the mouse), and at this time the Mark closest to the mouse click will be selected, which makes the selection of Mark more efficient and effective.

During specific implementation, the coordinates of the created readings on the aforementioned display screen are recorded before step 602 is performed, and the recorded coordinates of the created readings can be obtained when step 602 is performed. There are many recording methods, for example, the aforementioned method of creating an index table can be used for recording, and there can be other recording methods, such as creating a file for recording. In one embodiment, before obtaining the coordinate values of the created reading values of the display screen, it may further include: establishing an index table for the created reading values of the display screen, and the index table records that the display screen has been created The coordinate value of the reading value of the created display screen; then, obtaining the coordinate value of the read value created on the display screen may be implemented as: obtaining the coordinate value of the read value created on the display screen from the index table.

During specific implementation, the following situation may occur in the implementation of step 604: the minimum offset value may include multiple identical offset values, that is, an equidistant situation occurs. At this time, a priority rule may be preset, and when the minimum offset value includes multiple identical offset values, an offset value is selected from the multiple identical offset values according to the preset priority rule; The created reading corresponding to the selected offset value is set to the selected state. In this way, it can be guaranteed that there is only one reading value in the selected state when the equi-offset point occurs. Priority rules can be preset according to actual needs. For example, it can be set to select the first Mark on the left of the mouse, and of course other priority rules can also be defined as required.

In the specific implementation, after selecting the Mark, move the Mark to the desired position and read its value, that is, the positioning of the Mark, which is a common application method of the Mark. Because of the existence of the mouse, just set the Mark to be attached to the signal (The adsorption effect can be achieved through programming control), drag the selected Mark to the position where the value needs to be read. That is to say, in one embodiment, after setting the created read value corresponding to the minimum offset value to the selected state, it may further include: setting the selected read value to be attached to the signal; dragging the selected read value to value to position the selected reading value to the target position.

In addition to the above-mentioned method of dragging and positioning, the Mark can also be positioned by means of jump positioning during specific implementation, that is, the selected reading value can be positioned to the target position by clicking the target position with the mouse. After the Mark is selected, wherever the mouse clicks (clicks), the Mark will be positioned there. In this way, locating Mark is faster. Because in this jump positioning method, the position of the mouse click is not necessarily on the signal, so the Mark position can be set after the position of the mouse click is processed. During processing, you can choose whether to position the Mark based on the vertical axis or the horizontal axis. The positioning process can be well completed through the combination of keyboard and mouse click actions.

That is, the aforementioned positioning of the selected reading value to the target position by clicking the target position with the mouse may include: when the mouse clicks on the target position, select a positioning method based on vertical axis positioning or horizontal axis positioning through keyboard keys; method, retrieve the coordinate value of the signal, and compare the retrieved signal coordinate value with the coordinate value of the mouse click target position; determine the target position according to the comparison result, and locate the selected reading value to the target position.

During specific implementation, if the positioning method based on the vertical axis positioning is selected by the keyboard, the vertical coordinate value of the signal is retrieved, and the vertical coordinate value of the retrieved signal is compared with the vertical coordinate value of the mouse click target position; it is determined that the offset is the smallest The signal position corresponding to the ordinate value of the ordinate value is the target position, and the selected reading value is positioned to this position; if the positioning method based on the horizontal axis positioning is selected through the keyboard, the abscissa value of the signal is retrieved, and the retrieved signal’s Compare the abscissa value with the abscissa value of the mouse click target position; determine the signal position corresponding to the abscissa value with the smallest deviation as the target position, and locate the selected reading value to this position.

Mouse click can get the horizontal and vertical coordinates of the click, and the vertical coordinate (or horizontal coordinate) value of Mark can be set according to the different keyboard keys, that is, the positioning method based on vertical axis positioning or horizontal axis positioning can be selected by keyboard keys (here you can define the keyboard Ctrl key is to set the ordinate, Alt is to set the abscissa), for example: when the mouse is clicked and the Ctrl key is pressed at the same time, the abscissa of the mouse click is assigned to the selected Mark, and the ordinate values of all signals will be retrieved , find the first point closest to the ordinate value clicked by the mouse and move it there (ignoring the abscissa at this time).

Since the Mark may obtain the value on the signal, the signal can be analyzed through the operation of the Mark coordinate value. During the specific implementation, a Mark operation function is provided, which can perform subtraction, addition and multiplication operations. The formula can be: A+B or A-B or A*B, where A is the coordinate value of the selected Mark, and B is all other The coordinate value of the created Mark, the result of the operation is divided into two cases: 1. If the created Mark coordinate value is not updated, the operation result will not change; 2. If the created Mark coordinate value is updated, the operation result will change. Take subtraction as an example, select the coordinate value of a Mark (according to the Mark selected by the mouse) as the subtrahend, use the coordinate values of all created Marks as the minuend, and compare the coordinate values of the selected Mark with all created Marks respectively. Subtract the coordinate values (vertical axis data minus vertical axis data, horizontal axis data minus horizontal axis data), and then you will get the difference between the coordinate values of all created Marks and the selected Mark. That is, after setting the created reading value corresponding to the minimum offset value to the selected state, it may also include: performing an addition, subtraction or multiplication operation on the coordinate value of the created reading value and the coordinate value of the selected reading value ; Determine the difference between the corresponding signals according to the operation result.
