In order to more clearly illustrate the technical solutions of the present invention, the drawings that are needed in the description will be briefly introduced below, it being obvious that the drawings in the following description are only some embodiments of the present invention, and that other embodiments may be obtained according to these drawings without inventive effort for a person skilled in the art.
The characters, numbers, symbols, etc. on the figures are all displayed on the screen, panel, film for visual explanation.
In order to more intuitively embody the technical solution without misunderstanding, the numbers with leads and ' in the figures are reference numerals, for example, in fig. 1, the reference numerals 2' denote the interfaces 2'.
As shown in fig. 1:
the invention relates to a device of an intelligent oscillometer. The appearance has a shell 1', and the shell 1' has the following parts: two interfaces 2' of data and power supply, two meter pen interfaces 3', a display screen 4', a power supply key 5', a function key 6', two meter pens 7' respectively connected with the two meter pen interfaces 3', and an indicator lamp 8' arranged on the meter pen 7 '.
Except for the interface 2 'and the indicator lamp 8', the appearance of the intelligent oscillometer is consistent with that of the existing actually-used oscillometer.
But within the housing 1', the difference from the existing in-service oscilloscopes is that: the display screen 4 'is electrically connected with the interface 2'; the two meter pen interfaces 3 'are electrically connected with the interface 2'; a key circuit board 60 is mounted in the housing 1' at a position below the function keys 6', the key circuit board 60 being electrically connected to the interface 2'.
The key circuit board 60 corresponding to the function key 6 'is a device for generating a position signal of the function key 6', and any key pressing of the function key 6 'causes the key circuit board 60 to trigger a signal to be transmitted to the host computer 300 through the interface 2', and the host computer 300 calculates a current waveform symbol pattern by combining the information that the current pen 7 'touches the touch display 20' and transmits the current waveform symbol pattern to the display screen 4 'through the interface 2'.
An indicator light 8 'is also electrically connected to the interface 2'.
As shown in fig. 2 and 3:
in the prior art, a board in the form of a board having a front surface appearance as shown in fig. 2 and a rear surface appearance as shown in fig. 3, the board having a matrix-like insertion hole 100 'and further having symbols A, B, C, D for determining the position of the insertion hole 100', is used.
The various components 200 are inserted into the jack 100' and connected by wires to form a circuit.
The function key 6 'of the actual oscillography is set, the pen of the actual oscillography is used for contacting the jack at different positions of the circuit on the back of the plugboard to contact the circuit, and the potential waveform diagram of the point is displayed on the display screen 4' of the oscillography.
The present invention does not have a physical board but uses a touch display 20', the touch display 20' is connected to a host computer 300, and the host computer 300 can display a virtual circuit board 12' having a jack 100' on the touch display 20' through software.
The computer host 300 of the present invention can receive signals from the touch display 20 'and the housing 1', and can control the touch display 20 'and the housing 1'.
When the intelligent oscillometer is started to be used, the interface 2' integrating data and power supply is connected with the host computer 300, then the power supply key 5' is pressed, the display screen 4' is lightened, the meter pen 7' is inserted into the meter pen interface 3', and the indicator lamp 8' on the meter pen 7' is in a lighted state.
The touch display 20' is connected to the computer host 300, and the computer host 300 can display a virtual circuit board 12' having a jack 100' on the touch display 20' through software design, and a student or teacher can insert the virtual component 200 into the jack 100' by operating the computer host 300, and connect the virtual components with virtual wires to form a virtual simulation circuit.
This circuit board 12' is flipped over with the operation of the host computer 300, with the visual effect of the front or back being the same as on a real circuit board.
The teacher can also send the designed circuit board 12' to a plurality of touch displays 20' for students connected with the computer host 300 through the computer host 300, that is, one computer host 300 can connect and control a plurality of touch displays 20', and each touch display 20' is matched with a set of the shell 1' and the interfaces 2', the pen interfaces 3', the display screen 4', the power key 5', the function key 6', the pen 7', the indicator light 8', the key circuit board 60 provided in the shell 1', and the computer host 300 is respectively connected with the interfaces 22' of the multiple sets of the shells 1'.
At the beginning of measuring the three-dimensional virtual simulation circuit with physical properties on the touch display 20':
the two measured points on the circuit board 12' directly calculate various electrical parameter values, such as voltage, resistance, current, capacitance, due to the virtual circuit.
For example, when the potential value of the measured point 10 'on the circuit board 12' in fig. 4 is measured, the power button 5 'of the intelligent oscillometer is pressed first, and the position signal can be transmitted to the interface 2' and then transmitted to the host computer 300.
Then, when the pen tip of the stylus 7 'touches the touch display 20' and the measured point 10 'on the measured circuit board 12' touches the touch display 20', the stylus 7' generates a touch signal, and the touch signal is sent to the host computer 300 through the stylus interface 3 'and the interface 2'.
The position of the touch display 20' touched by the stylus 7' is also fed back to the host computer 300, the host computer 300 correlates the touch signal fed back by the stylus 7' with the position signal touched by the touch display 20' through a program, and when the stylus 7' feeds back the touch signal, the position signal touched by the touch display 20' is fed back, and the validity of the position signal touched by the touch display 20' is judged.
Thus, the position of the touch display 20 'touched by the stylus 7' is determined, and the position signal fed back by the touch display 20 'is ensured to be generated by the touch of the stylus 7', so that touch erroneous judgment of other articles is avoided.
The image of each jack 100 'on the touch display 20' has a certain position, and the host computer 300 determines the position signal touched on the touch display 20 'to determine whether the stylus 7' is touched at the position of a certain jack 100', that is, whether the stylus 7' is touched at the proper position of the measured point.
When two pens 7' contact the appropriate position of the measured point, that is, when both pens 7' contact the jack 100', the host computer 300 controls the indicator light 8' on the pens to be not on, which indicates that the pens 7' contact the appropriate position of the measured object.
For example, the pen 7' touches the measured point 10' on the measured circuit board 12' on the touch display 20', the host computer 300 starts to calculate the potential value on the measured point 10' according to the circuit composed by the virtual components 200, calculates and draws the current potential pattern according to the time, and sends the calculation result to the display 4', at this time, the display 4' displays the measured potential value pattern.
The software of the present invention can be designed by those skilled in the art based on the prior art and conventional software.

The design and use mode of the device belongs to the first time in China, and fills the blank that the real device is used for measuring the physical attribute value of the three-dimensional virtual simulation circuit in China.
