Based on the above thought, the embodiment of the present application provides a speed-adjustable nixie tube automatic display method, and specifically, refer to fig. 1, which is a schematic flow chart of the speed-adjustable nixie tube automatic display method according to the embodiment of the present invention, and the method specifically includes the following contents.
S11: and receiving and responding to a first type of trigger operation, and controlling a square wave generator to generate a preset square wave signal, wherein the first type of trigger operation is an operation for indicating automatic display of the nixie tube.
In this embodiment, the nixie tubes to be subjected to the display test (for example, the diodes to be tested, etc.) may be pre-arranged and connected in the electronic device for performing the adjustable-speed nixie tube automatic display method provided by the present application.
Specifically, referring to the schematic structural diagram of the electronic device applying the speed-adjustable nixie tube automatic display method shown in fig. 2, the electronic device at least includes: the circuit structure comprises a square wave generator, a speed regulator, a shift register, a signal amplifier, a driving circuit, a display testing component and the like. When the square wave generator is implemented, a timer can be used for generating a square wave signal meeting a certain period requirement and a duty ratio requirement. It is to be understood that, the electronic device may further include a processor for controlling the above-mentioned multiple circuit structures to cooperatively operate to complete the display test of the nixie tube.
In this embodiment, the first type of trigger operation may be specifically understood as a designation operation for indicating an automatic display nixie tube, and may specifically be, for example, a pressing operation of a button labeled with "automatic display", or a double-click operation of a certain control key, or a rotation operation of rotating a preset knob to a position labeled with "automatic display", or the like. The present specification is not limited to the specific type of the first type of trigger operation described above.
In this embodiment, in a specific implementation, the electronic device may receive an operation initiated by a user, and then detect whether the operation initiated by the user is consistent with a specified operation for instructing to automatically display the nixie tube, so as to determine whether the received user operation is a first type of trigger operation. In the case where it is determined that the received user operation is a first type of trigger operation, the apparatus may be controlled to enter an automatic display mode in response to the first type of trigger operation.
The automatic display mode may be specifically understood as an operation mode described as follows: the electronic equipment automatically displays (or lights) the strokes in the nixie tube one by one or simultaneously displays a plurality of strokes in the nixie tube according to a certain display speed so as to detect the display quality of the nixie tube, so that the condition that workers need to manually and one by one shift corresponding switches in the nixie tube to display the corresponding strokes in the nixie tube based on the existing method can be avoided, the operation can be simplified, and the implementation efficiency is improved.
In this embodiment, after entering the automatic display mode in response to the first type of trigger operation initiated by the user, the processor may first control the square wave generator to generate a preset square wave signal.
The preset square wave signal may be specifically understood as a square wave signal with a signal period and a duty ratio of a certain stable value. The preset square wave signal is used for triggering the display of the nixie tube subsequently, and the numerical values of the signal period and the duty ratio of the preset square wave signal can influence the display speed of the nixie tube.
It should be noted that the preset signal period and duty ratio of the square wave signal may be flexibly set according to user requirements. For example, the user can adjust the values of the signal period and the duty ratio of the preset square wave signal by adjusting the capacitor and the resistor in the square wave generator according to the needs.
In this embodiment, in specific implementation, a first type of trigger operation initiated by a user may be received, and the processor responds to the first type of trigger operation and controls the square wave generator to generate a preset square wave signal.

In this embodiment, the preset process may specifically include at least one of the following: signal shift processing, signal amplification processing, signal drive processing, and the like. It should be noted that the above-mentioned preset processing is only for better explaining the embodiments of the present specification. Other types of processing may also be included in the implementation, depending on the particular circumstances and the particular requirements. The present specification is not limited to these.
In this embodiment, in a specific implementation, the processor may perform signal shift processing on the preset square wave signal by controlling the shift register, so as to shift and transmit the preset square wave signal to a next circuit structure for next preset processing.
In this embodiment, when the preset square wave signal is transferred through the shift register, in order to avoid the output signal from being disordered due to the unstable initial state and affecting the processing precision of the preset square wave signal, in the specific implementation, the signal input terminal of the shift register may be grounded to avoid the unstable initial state.
In this embodiment, in a specific implementation, the processor may perform signal amplification processing on the weak preset square wave signal through the signal amplifier. Specifically, a preset square wave signal which originally can only trigger a control electronic device of 5V can be amplified to an electronic device capable of triggering a control electronic device of 12V by a signal amplifier. Of course, the signal amplification process listed above is only a schematic illustration. In specific implementation, the preset square wave signal can be amplified to a certain degree according to specific conditions. The present specification is not limited to these.
In this embodiment, in specific implementation, the processor may drive a preset square wave signal through the driving circuit to perform signal driving processing, so as to enter a next circuit structure. For example, after a predetermined square wave signal is driven, the square wave signal is input to a display test module to perform a specific display test.
In this embodiment, considering that the driving circuit requires a relatively small contact resistance in the on state during use, so as to reduce the influence of the driving circuit on the subsequent circuit structure, such as the display test module, some devices with a small voltage drop or a small contact resistance may be used as the driving circuit, so as to reduce the influence of the driving circuit on the next circuit structure.
In this embodiment, in a specific implementation, as shown in fig. 2, after the square wave generator generates a preset square wave signal, the processor may first control the shift register to perform signal shift processing (i.e., first processing) on the preset square wave signal, so as to obtain a first processed square wave signal; then, the signal amplifier is controlled to amplify the signal of the square wave signal after the first processing (namely, the second processing) to obtain the square wave signal after the second processing; and then controlling the driving circuit to perform signal driving processing (namely, third processing) on the square wave signal after the second processing to obtain a square wave signal after the third processing, wherein the square wave signal after the third processing is used as a processed square wave signal corresponding to the preset square wave signal.
S15: and controlling the nixie tube to display according to the corresponding display speed according to the signal period and the duty ratio of the processed square wave signal.
In this embodiment, after obtaining the processed square wave signal, the processor may control the display test component to determine a corresponding display speed according to a signal period and a duty ratio of the processed square wave signal; and then, displaying each stroke in the nixie tube arranged on the display test component one by one according to the determined display speed, and/or simultaneously displaying a plurality of strokes in the nixie tube according to the determined display speed, and the like.
In this embodiment, it is to be added that the display testing component may be a testing base connected with a testing power supply, and the switch corresponding to each stroke in the nixie tube may be electrically connected to the testing component in advance. Therefore, when the processed square wave signal enters the display test assembly, the display test assembly can control the specific display of the nixie tube according to the processed square wave signal.
In this embodiment, after controlling the nixie tube to display according to the corresponding display speed according to the signal period and the duty ratio of the processed square wave signal, when the method is implemented, the following may be further included: and detecting each stroke displayed by the nixie tube according to the corresponding display speed and whether the displayed multiple strokes meet the preset display requirement, and determining whether the quality of the nixie tube is qualified.
In this embodiment, specifically, if it is detected that an abnormality occurs when a certain stroke in the nixie tube is displayed alone, for example, if the certain stroke is not lit, it can be determined that the pressure drop performance of the nixie tube is abnormal, and it can be determined that the preset display requirement is not met, and the quality of the nixie tube is not qualified. If it is detected that an abnormality occurs when a plurality of strokes are displayed together in the nixie tube, for example, when the plurality of strokes are lit up, a color difference exists between different displayed strokes, it can be determined that a preset display requirement is not met, the quality of the nixie tube is not qualified, and the like. By the mode, the nixie tube can be efficiently and accurately automatically subjected to display test to determine whether the quality of the nixie tube is qualified or not, so that the unqualified nixie tube can be timely found.
In the embodiment of the application, an automatic display mode is switched according to a first type of trigger operation initiated by a user, and a preset square wave signal is automatically generated by using a square wave generator in the automatic display mode, so that the corresponding display speed is determined according to the signal period and the duty ratio of the preset square wave signal; and then can be based on this predetermined square signal, according to the digital tube that the demonstration speed automatic display waited to detect who corresponds, avoided current method because the operation that needs artifical manual control display switch to lead to existence is troublesome, loaded down with trivial details, inefficiency, the technical problem that misoperation appears easily, reached the technical effect that can each stroke and a plurality of strokes of automatic, high-efficient demonstration digital tube.
In one embodiment, the preset processing may specifically include at least one of: signal shift processing, signal amplification processing, signal drive processing, and the like. In specific implementation, one or a combination of multiple processing manners listed above may be adopted to perform the preset processing on the preset square wave signal according to specific situations and processing needs, so as to obtain a processed square wave signal that can be used for subsequently controlling the nixie tube to display at a corresponding display speed.
Of course, it should be noted that the above-listed preset processing is only an exemplary one. In specific implementation, other suitable processing methods besides the above-mentioned processing methods can be introduced for the preset processing according to specific situations and processing needs. The present specification is not limited to these.
In one embodiment, in order to meet the personalized requirements of the user, the display speed can be adjusted according to the requirements of the user according to specific situations, and the nixie tube is displayed according to the adjusted display speed so as to better perform the display test on the nixie tube, in the specific implementation, as shown in fig. 2, a speed regulator can be arranged on the electronic device in advance. The speed regulator is connected with the square wave generator and is used for adjusting the display speed of the nixie tube by adjusting a preset square wave signal generated by the square wave generator.
In this embodiment, the speed regulator may be a preset circuit structure including a capacitor, a resistor, and the like, and the circuit structure is connected to the square-wave generator, and in a specific implementation, the circuit structure of the square-wave generator generating the preset square-wave signal may be influenced by adjusting the capacitor and/or the resistor in the speed regulator connected to the square-wave generator in a manner of capacitor matching and/or resistor matching, so as to adjust a signal period and an air-to-space ratio of the preset square-wave signal generated by the square-wave generator.
In this embodiment, after receiving the first type of trigger operation, when the method is implemented specifically, the following may be further included: and receiving and responding to a speed adjusting instruction, and adjusting the signal period and the duty ratio of a preset square wave signal generated by a square wave generator by adjusting a capacitor and/or a resistor in a speed adjuster to obtain the adjusted preset square wave signal, wherein the speed adjuster is a preset circuit structure which is distributed in advance and connected with the square wave generator.
In this embodiment, the speed adjustment instruction may be specifically understood as an instruction sentence or an instruction operation initiated by a user for instructing to adjust the display speed.
In this embodiment, in a specific implementation, the processor may adjust a signal period and a duty ratio of the preset square wave signal generated by the square wave generator by adjusting a capacitor and/or a resistor in the speed adjuster according to the speed adjustment instruction, so as to obtain the adjusted preset square wave signal. Since the preset square wave signal after the pre-adjustment is different from the preset square wave signal without the pre-adjustment in signal period and duty ratio, the display speed of the nixie tube is changed (for example, the display speed is adjusted relatively faster or slower) when the nixie tube is displayed based on the adjusted square wave signal, so that the display speed of the nixie tube in the automatic display mode can be flexibly adjusted according to specific conditions and user needs.
In an embodiment, after controlling the nixie tube to display according to the corresponding display speed according to the signal period and the duty ratio of the processed square wave signal, when the method is implemented, the following may be further included: and detecting each stroke displayed by the nixie tube according to the corresponding display speed and whether the displayed multiple strokes meet the preset display requirement, and determining whether the quality of the nixie tube is qualified.
In this embodiment, in a specific implementation, the display condition of the nixie tube displayed according to the corresponding display speed may be detected, and whether the quality of the nixie tube is qualified may be determined through the display detection. Specifically, for example, if it is detected that an abnormality occurs when a certain stroke in the nixie tube is displayed alone, for example, if the certain stroke is not lit, it can be determined that the pressure drop performance of the nixie tube is possibly abnormal, and it can be determined that the preset display requirement is not met, and the quality of the nixie tube is not qualified. If it is detected that the plurality of strokes in the nixie tube are abnormal when being displayed together, for example, when the plurality of strokes are lightened, a relatively obvious color difference exists between different displayed strokes, it can be determined that the preset display requirement is not met, the quality of the nixie tube is not qualified, and the like. Of course, the above-listed display detection method is only an exemplary description. In specific implementation, according to specific conditions and detection requirements, other suitable detection modes can be adopted for display detection to determine whether the quality of the nixie tube is qualified.
By the mode, the nixie tube can be efficiently and accurately automatically subjected to display test to determine whether the quality of the nixie tube is qualified or not, unqualified nixie tubes are timely found, and the processing efficiency is improved.
In one embodiment, to further satisfy the user's personalization requirements, to allow the user to manually and flexibly control the display of the nixie tube. In specific implementation, as shown in fig. 2, the electronic device may further include a manual square wave generator. The manual square-wave generator can be used for acquiring and generating square-wave signals with corresponding frequencies as preset square-wave signals according to case operations of a user, and then the display speed of the nixie tube can be controlled through the preset square-wave signals.
In this embodiment, the method, when implemented, may include the following: and receiving and responding to a second type of trigger operation, and generating a square wave signal with corresponding frequency as a preset square wave signal according to the key operation of a user, wherein the second type of trigger operation is used for indicating the operation of manually displaying the nixie tube.
In this embodiment, the second type of trigger operation may be specifically understood as a designation operation for indicating a manual display of a nixie tube, and may specifically be, for example, a pressing operation of a button labeled with "manual display", or a clicking operation of a certain control key, or a rotating operation of rotating a preset knob to a position labeled with "manual display", or the like. The description is not limited to the specific type of the second type of trigger operation.
In this embodiment, in a specific implementation, the electronic device may receive an operation initiated by a user, and then detect whether the operation initiated by the user is consistent with a specified operation for instructing to manually display the nixie tube, so as to determine whether the received user operation is a second type of trigger operation. In the event that it is determined that the received user operation is a second type of trigger operation, the device may be controlled to enter a manual display mode in response to the second type of trigger operation.
The manual display mode may be specifically understood as an operation mode described as follows: the electronic equipment adjusts the display speed of the nixie tube in real time according to the key operation of the user, displays (or lights) the strokes in the nixie tube one by one or simultaneously displays a plurality of strokes in the nixie tube according to the display speed adjusted in real time so as to detect the display quality of the nixie tube, thus meeting the requirement that the user wants to manually control the specific display of the nixie tube and further improving the use experience of the user.
In this embodiment, after entering the manual display mode in response to the second type of trigger operation initiated by the user, the user may manually press the designated operation key according to the prompt and the needs and at a certain frequency or key speed. The electronic equipment can collect the key operation of the user, identify the operation frequency or the operation speed corresponding to the key operation of the user to determine the corresponding frequency, further control the manual square wave generator to generate the square wave signal with the corresponding frequency as a preset square wave signal, and then display the subsequent nixie tube by utilizing the preset square wave signal, so that the effect of adjusting the display speed of the nixie tube in real time can be achieved by changing the corresponding frequency of the preset square wave signal in real time according to the key operation of the user.
Specifically, for example, the user wants to slow down the display speed of the nixie tube, the speed of the key operation can be slowed down, so that the electronic device can recognize the latest key operation speed of the user, determine the corresponding frequency with a relatively small value according to the latest key operation speed with the relatively small value, further generate the corresponding preset square wave signal according to the corresponding frequency, and subsequently display the nixie tube at the relatively small value display speed based on the preset square wave signal.
From the above description, it can be seen that, compared with the existing method, in the speed-adjustable automatic display method for the nixie tube according to the embodiment of the present application, since the automatic display mode is switched according to the first type of trigger operation initiated by the user, the preset square wave signal is automatically generated by using the square wave generator in the automatic display mode, so as to determine the corresponding display speed according to the signal period and the duty ratio of the preset square wave signal; the digital tube to be detected can be automatically displayed according to the corresponding display speed based on the preset square wave signal, so that the technical problems of troublesome and tedious operation, low efficiency and easy misoperation caused by the fact that a display switch is manually controlled in the conventional method are solved, and the technical effect of automatically and efficiently displaying each stroke and a plurality of strokes of the digital tube is achieved; the signal period and the duty ratio of a preset square wave signal generated by the square wave generator are adjusted by pre-arranging and connecting the speed regulator with the square wave generator and adjusting the capacitance and/or the resistance in the speed regulator, so that the display speed of the nixie tube can be efficiently and accurately adjusted according to specific processing requirements, and the nixie tube can be conveniently displayed according to the personalized requirements of a user; and switching the manual display model in response to the second type of trigger operation, generating and using a square wave signal with a frequency corresponding to the operating frequency of the key operation of the user as a preset square wave signal according to the key operation of the user in the manual display mode to control the display of the nixie tube, so that the effect of flexibly controlling the nixie tube to carry out corresponding display according to the requirement of the user based on the manual operation of the user is achieved.
Based on the same inventive concept, the embodiment of the present application further provides an automatic display device for a nixie tube, which is capable of adjusting the speed, as described in the following embodiments. The problem solving principle of the speed-adjustable nixie tube automatic display device is similar to that of the speed-adjustable nixie tube automatic display method, so that the implementation of the speed-adjustable nixie tube automatic display device can refer to the implementation of the speed-adjustable nixie tube automatic display method, and repeated parts are not described again.

From the above description, it can be seen that, in the speed-adjustable nixie tube automatic display device provided in the embodiment of the present application, the first processing module switches the automatic display mode according to the first type of trigger operation initiated by the user, and the square wave generator is used to automatically generate the preset square wave signal in the automatic display mode, so as to determine the corresponding display speed according to the signal period and duty cycle of the preset square wave signal; the to-be-detected nixie tube can be automatically displayed according to the corresponding display speed through the second processing module and the display module based on the preset square wave signal, so that the technical problems of troublesome and tedious operation, low efficiency and easy misoperation caused by the fact that a display switch is manually controlled in the conventional method are solved, and the technical effect of automatically and efficiently displaying each stroke and a plurality of strokes of the nixie tube is achieved; the signal period and the duty ratio of a preset square wave signal generated by the square wave generator are adjusted by pre-arranging and connecting the speed regulator with the square wave generator and adjusting the capacitance and/or the resistance in the speed regulator through the first processing module, so that the display speed of the nixie tube can be efficiently and accurately adjusted according to specific processing requirements, and the nixie tube can be conveniently displayed according to the personalized requirements of a user; and the first processing module responds to the second type of trigger operation to switch the manual display model, and generates and utilizes a square wave signal with a frequency corresponding to the operating frequency of the key operation of the user as a preset square wave signal to control the display of the nixie tube according to the key operation of the user in the manual display mode, so that the effect of flexibly controlling the nixie tube to carry out corresponding display according to the requirement of the user and based on the manual operation of the user is achieved.
Based on the above speed-adjustable nixie tube automatic display device, the application also provides speed-adjustable nixie tube automatic display equipment, wherein the equipment can comprise the functional modules related to the speed-adjustable nixie tube automatic display device, so that corresponding functional application can be realized.
In a specific scene example, the method and the device for automatically displaying the speed-adjustable nixie tube provided by the application can be applied to efficiently and accurately finish quality sampling inspection of the nixie tube to be detected. Specifically, referring to fig. 2 and a scene schematic diagram of a method and an apparatus for automatically displaying a speed-adjustable nixie tube, which are provided by the embodiment of the present invention and are applied in a scene example, shown in fig. 4, are performed as follows.
In this scenario example, based on the speed-adjustable nixie tube automatic display method and apparatus provided by the present application, the speed-adjustable principle mainly includes that a square wave generator generates a corresponding square wave signal (i.e., a preset square wave signal), and a capacitor and a resistor in a circuit of the square wave generator are changed to change a duty ratio of a high level of the generated square wave signal, so as to change a period and a duty ratio of the square wave signal, thereby realizing control of a speed (i.e., a display speed). And then the generated square wave signals can be transferred in a shifting way, the transferred signals are amplified, and then the signals are used for driving the display of the nixie tube.
In one implementation, as shown in FIG. 2, first, a selector (e.g., a knob for selecting a mode) can be used to select the manual display mode or the automatic display mode.
If the automatic display mode is selected, a square wave generator can be used for automatically generating a square wave signal, and then the automatic square wave signal controls the movement of the shift register to perform subsequent processing. In addition, the circuit can also utilize a timer and a peripheral circuit to output square wave signals with a certain period. The period and the duty ratio of the output square wave signal are controlled by adjusting a speed regulator of a peripheral circuit. Thereby realizing the control and adjustment of the display speed.
Secondly, if the manual display mode is selected, a square wave signal with unfixed frequency can be produced through manual key operation and a manual square wave generator, then the signal is input into the shift register, the shift speed of the shift register is controlled, subsequent processing is carried out, and the purpose of manual display is achieved. Wherein, if the manual display mode is selected, there may be no function of automatically adjusting the speed, and the speed displayed at this time may be determined by the speed of the manual key.
For a square wave signal generated in the above manner, the shifting of the signal can be realized by a shift register. The shift register needs to receive a square wave signal of a previous stage, but it should be noted that an input signal end of the shift register needs to be grounded through a resistor first, and if the input signal end of the shift register is not grounded, an initial state is unstable, so that an output signal is disordered. Therefore, an unstable state can be avoided, and the accuracy of the signal shift transmission process is ensured.
After the shift processing of the square wave signal is completed, the signal can be input to a signal amplifier so as to amplify the weak and small signal generated by the shift register, thereby realizing the function of controlling the 12V signal by using 5V to further drive the element with larger current to work.
Further, the signal may enter the driving circuit portion after being amplified. The contact resistance of the driving circuit part in a conducting state is small when the driving circuit part is used, so that the influence on a subsequent display test process is reduced, and the part needs to be careful in device selection. If a device with a certain voltage drop or large contact resistance is used, the forward voltage drop of the diode is no longer accurate when the diode (a nixie tube) is tested subsequently, so that the influence of the device needs to be removed. Therefore, in the specific implementation, the problem is to be avoided, so as to improve the accuracy of the subsequent detection.
Finally, the signal after being driven and processed by the driving circuit is input into a testing part (namely, a display testing component), and during specific implementation, the signal can be led alone, a power supply is provided by QT2, a diode characteristic curve can be displayed on QT2, the part is equivalent to a switch, and the signal can be independently connected with 1 pen for single-pen display and can also be simultaneously connected with a plurality of pens for multi-pen display. And determining whether the quality of the digital code is qualified or not according to the display result.
In this field example, in a specific implementation, for the output driving portion, referring to a scene schematic diagram of a scene example that is shown in fig. 5 and to which the speed-adjustable nixie tube automatic display method and apparatus provided by the embodiment of the present invention are applied, a two-stage amplifying circuit including 2 triodes may be used to drive a relay, and the actuation and the disconnection of the relay may also be implemented. Meanwhile, the nixie tube can be directly driven by using the shift register, so that the display of the nixie tube is realized.
By the mode, when the electronic pen is implemented, the timer can be used as a trigger signal, the electronic pen can be lightened one by one through the trigger key, the problem that the electronic pen is lightened by manually shifting the dial switch one by one in the prior art is solved, and the risk of wrong dialing is reduced. And the aim of adjusting the automatic display speed is fulfilled by utilizing the matching design of the capacitor and the resistor, and the aim of improving the inspection efficiency which cannot be realized manually in the prior art is solved. And the purposes of manually lighting the key and automatically lighting each stroke are realized by controlling the jumping of the input signal of the shift register.
Compared with other testing methods, the method provided by the application can obtain the following beneficial effects: the frock uses 1 dip switch, and 1 dabs the switch and triggers, has saved 7 dip switches, has avoided showing which pen and does not know which dip switch's of fluctuation drawback. The manual and automatic dual display purposes are realized, the original manual function is reserved, the optimization is carried out on the original basis, and the manual lightening can be realized only by pressing one dial switch; the automatic lighting is that one more toggle dial switch is not needed to be lighted, or the keys are lighted, and the automatic lighting by strokes can be realized by pressing the keys once; the display speed can be adjusted, and the inspection efficiency is improved. Based on the method, the testing tool base (such as the testing base) can be relatively independent, and the base can be directly replaced after aging, so that the problem of difficulty in later maintenance is solved.
According to the scene example, the speed-adjustable nixie tube automatic display method and device provided by the embodiment of the application are verified, the automatic display mode is switched according to the first type of trigger operation initiated by a user, and the square wave generator is used for automatically generating the preset square wave signal in the automatic display mode, so that the corresponding display speed is determined according to the signal period and the duty ratio of the preset square wave signal; and then can be based on this predetermined square signal, according to the digital tube that the demonstration speed automatic display waited to detect who corresponds, avoided current method because the operation that needs artifical manual control display switch to lead to existence is troublesome, loaded down with trivial details, inefficiency, the technical problem that misoperation appears easily, reached the technical effect that can each stroke and a plurality of strokes of automatic, high-efficient demonstration digital tube.
