Technical Field
[0001] This application relates to the technical field of oscilloscopes, and more particularly, to an auxiliary device and an oscilloscope device. Background Art
[0002] In the fields of industrial engineering and science education, an oscilloscope is an essential basic tool in experiments, manufacturing production, testing, and other processes. Currently, when an oscilloscope is used to troubleshoot and test abnormal phenomena of a product, the user needs to hold the probe of the oscilloscope and touch the potential points of the product and the fault back and forth. At this time, there are situations where both hands are holding the probe or one hand is holding the probe while the other hand adjusts the operation of the oscilloscope. When a single person uses the oscilloscope for testing, there is no free manpower left to operate the oscilloscope to stop refreshing the display screen. As a result, it is necessary to seek other manpower to operate the oscilloscope to refresh the display screen, which reduces the testing efficiency of the oscilloscope and increases the labor cost. Summary of the Utility Model
[0003] The embodiments of this application provide an auxiliary device and an oscilloscope device, which are mainly used to solve the problem that when a single person uses an oscilloscope for testing, it is necessary to seek other manpower to operate the oscilloscope to refresh the display screen, which reduces the testing efficiency of the oscilloscope and increases the labor cost.
[0004] The auxiliary device of the embodiments of this application is used for an oscilloscope. The auxiliary device includes a switch assembly and a control assembly. The switch assembly is used to generate a trigger signal when triggered; the control assembly is electrically connected to the switch assembly, and the control assembly is used to generate a control instruction according to the trigger signal and send the control instruction to the oscilloscope. The control instruction is used to control the oscilloscope to refresh and stop refreshing the display screen of the oscilloscope.
[0005] In this way, the auxiliary device can generate a control instruction to control the refresh of the display screen of the oscilloscope. Thus, in the case where the user's hands cannot control the refresh of the display screen of the oscilloscope, the user can use at least one of the feet, voice, and other body parts to control the switch to generate a trigger signal, and the trigger signal can be transmitted to the oscilloscope after being converted by the control assembly, so that the refresh or stop of the display screen of the oscilloscope can be controlled. Furthermore, there is no need for an additional person to help the user with the operation, saving labor costs and improving the testing efficiency of the oscilloscope at the same time.
[0006] In some embodiments, the switch assembly includes at least one of a foot switch, a voice control switch, and a proximity sensor.
[0007] In this way, according to the user's usage habits, the switch assembly can be determined as at least one of a foot switch, a voice control switch, and a proximity sensor, so that a trigger signal can be generated in different environments for oscilloscope testing.
[0008] In some embodiments, the oscilloscope includes a data interface, and the auxiliary device is used to be detachably connected to the data interface through a data cable, and the control instruction is transmitted to the data interface through the data cable.
[0009] In this way, when a single person uses the oscilloscope for testing and there is no free hand to operate the oscilloscope to stop refreshing the display screen, the oscilloscope can be controlled to refresh the display screen by connecting the auxiliary device to the data interface of the oscilloscope through a data cable. When the auxiliary device is not needed, it can be detached from the oscilloscope without the need to disassemble the oscilloscope for physical modification and add extra testers, thereby improving the testing efficiency and saving costs.
[0010] In some embodiments, the control component includes a switch detector and an instruction converter. The switch detector is electrically connected to the switch component and the instruction converter. The switch detector is used to detect whether the switch component is triggered, and the instruction converter is used to convert the trigger signal into the control instruction.
[0011] In this way, by setting a switch detector and an instruction converter in the auxiliary device, the intention of the user to refresh the oscilloscope screen can be converted into a trigger signal for the instruction converter, and the instruction converter can generate an instruction capable of controlling the oscilloscope to refresh the screen according to the trigger signal and send it to the oscilloscope for control.
[0012] In some embodiments, the switch detector includes a voltage regulator diode, a first resistor, a second resistor, a third resistor, and a capacitor. The voltage regulator diode is connected in series with the first resistor, the voltage regulator diode is connected in parallel with the second resistor and the third resistor, the first resistor, the second resistor, and the third resistor are connected in series, and the capacitor is connected in parallel with the third resistor.
[0013] In this way, by setting a voltage regulator diode, resistors, and a capacitor in the switch detector, a corresponding trigger signal can be generated according to the change in the level, and a corresponding control instruction can be generated according to the trigger signal.
[0014] In some embodiments, the instruction converter includes a micro control unit, an Internet protocol address soft core module, a physical address management interface, and a port physical layer. The port physical layer is electrically connected to the micro control unit and the oscilloscope. The trigger signal generates the control instruction via the micro control unit, and the control instruction is transmitted to the port physical layer via the Internet protocol address soft core module and the physical address management interface, and the control instruction is transmitted to the oscilloscope via the port physical layer.
[0015] In this way, after the trigger signal is transmitted to the instruction converter, the microcontroller unit can convert the trigger signal into corresponding control instructions, and then the Internet Protocol address soft core module and the physical address management interface can improve the accuracy of transmission to the port physical layer. Finally, it can be directly transmitted to the oscilloscope through the port physical layer, thereby realizing the refresh of the display screen of the oscilloscope.
[0016] In some embodiments, the instruction converter includes a microcontroller unit, an Internet Protocol address hard core module, a physical address management interface, and a port physical layer. The port physical layer is electrically connected to the microcontroller unit and the oscilloscope. The trigger signal generates the control instruction via the microcontroller unit, and the control instruction is transmitted to the port physical layer via the Internet Protocol address hard core module and the physical address management interface, and the control instruction is transmitted to the oscilloscope via the port physical layer.
[0017] In this way, after the trigger signal is transmitted to the instruction converter, the microcontroller unit can convert the trigger signal into corresponding control instructions, and then the Internet Protocol address hard core module and the physical address management interface can improve the accuracy of transmission to the port physical layer. Finally, it can be directly transmitted to the oscilloscope through the port physical layer, thereby realizing the refresh of the display screen of the oscilloscope.
[0018] In some embodiments, the switch detector includes a first DIP switch and at least two second DIP switches. The refresh mode of the oscilloscope is switched according to the conduction and disconnection of the first DIP switch, and the control instruction adapted to the oscilloscope is selected according to the conducted second DIP switch.
[0019] In this way, when the oscilloscope includes different refresh modes, by setting the first DIP switch in the switch detector, the oscilloscope can select the refresh mode according to the DIP generated by the on / off of the first DIP switch.
[0020] Since there are different brands of oscilloscopes and their control instructions will also be different, by setting the second DIP switches corresponding to the brands in the switch detector, according to different oscilloscopes, the second DIP switches can generate corresponding DIPs, so that the instruction converter can send the correct control instructions to the oscilloscope according to different DIPs.
[0021] In some embodiments, the auxiliary device includes a power interface, which is used to connect to an external power supply to supply power to the auxiliary device by the external power supply through the power interface, and is detachably connected to the external power supply.
[0022] Thus, by providing a power interface on the auxiliary device, power can be quickly supplied to the auxiliary device by connecting it to an external power source through the power interface. By detachably connecting the power interface to an external power source, different external power sources can be adapted. In the case where one external power source is occupied, the auxiliary device can be connected to other external power sources.

[0039] Please refer to Figure 1 , the auxiliary device 20 of the embodiment of the present application is used for the oscilloscope 10. The auxiliary device 20 includes a switch component 21 and a control component 22. The switch component 21 is used to generate a trigger signal when triggered; the control component 22 is electrically connected to the switch component 21. The control component 22 is used to generate a control instruction according to the trigger signal and send the control instruction to the oscilloscope 10. The control instruction is used to control the oscilloscope 10 to refresh or stop refreshing the display screen of the oscilloscope 10.
[0040] In this way, the auxiliary device 20 can generate a control instruction for refreshing the display screen of the oscilloscope 10. Thus, in the case where the user's hands are unable to control the refresh of the display screen of the oscilloscope 10, the user can control at least one of the switch component 21 to generate a trigger signal through the foot, voice, and other body parts, and the trigger signal can be transmitted to the oscilloscope 10 after being converted by the control component 22, so as to be able to control the refresh of the display screen of the oscilloscope 10. Furthermore, there is no need for an additional person to assist the user in the operation, saving labor costs and improving the test efficiency of the oscilloscope 10 at the same time.
[0041] Among them, the oscilloscope device 100 is an instrument used to measure the waveforms of alternating current or pulsed current waves. The oscilloscope device 100 includes an oscilloscope 10 and an auxiliary device 20. A user can observe on the display screen of the oscilloscope 10 the waveform curves of various different signal amplitudes changing with time. For example, the waveform curves of signals such as voltage, current, frequency, phase difference, and amplitude changing with time can be observed on the display screen of the oscilloscope 10.
[0042] During the product R & D and testing process, the oscilloscope 10 is needed to troubleshoot abnormal phenomena of the product. The probe of the oscilloscope 10 needs to be contacted at the test points of different measured positions, and there is a situation where no test points are reserved at the measured positions. At this time, the user needs to hold the probe by hand and touch the potential points of the product's operating faults back and forth. However, there are situations where both hands of the user are holding the probe, or one hand is holding the probe and the other hand is adjusting the operating conditions of the product. When the user conducts the product test alone, there is no free hand to operate the oscilloscope 10 to stop refreshing the display screen, resulting in the user being unable to observe the display screen of the oscilloscope 10 when the product has problems. If the trigger mode for refreshing the display screen of the oscilloscope 10 is set to the single-trigger wait / stop refresh mode, false triggering will occur when the probe touches the measured point and jitters, causing the refresh of the display screen of the oscilloscope 10 to stop; while if the trigger mode for refreshing the display screen of the oscilloscope 10 is set to the normal trigger, there will be jitters when the probe detaches from the measured point, resulting in the display screen of the oscilloscope 10 being refreshed again and unable to stay on the required recorded screen.
[0043] Specifically, the oscilloscope 10 includes a data interface 11, and the data interface 11 can be used to transmit data. Among them, the data interface 11 can be an RJ45 network interface, a GPIB interface, a USB interface, a Lightning interface, a Type A interface, a Type B interface, a Type C interface, etc. The auxiliary device 20 can be detachably connected to the data interface 11 through a data cable. When the auxiliary device 20 is connected to the data interface 11, control instructions can be transmitted to the data interface 11 through the data cable. When the auxiliary device 20 is not needed, the auxiliary device 20 can be disconnected from the oscilloscope 10 by pulling out the data cable at the data interface 11, thus facilitating disassembly. In this way, when a single person uses the oscilloscope 10 for testing and has no free hand to operate the oscilloscope 10 to stop refreshing the display screen, the oscilloscope 10 can be controlled to refresh the display screen by connecting the auxiliary device 20 to the data interface 11 of the oscilloscope 10 through a data cable. When the auxiliary device 20 is not needed, the auxiliary device 20 can be detached from the oscilloscope 10 without having to disassemble the oscilloscope 10 for physical modification and without adding extra testers, thereby improving the test efficiency and saving costs. The auxiliary device 20 and the oscilloscope 10 can be connected by means of wireless communication. The connection methods of wireless communication include but are not limited to Bluetooth connection, radio frequency connection, or wireless local area network connection, etc.
[0044] Optionally, in some embodiments, the auxiliary device 20 can be integrated into the oscilloscope 10. By communicating and connecting the auxiliary device 20 with the oscilloscope 10, the display screen of the oscilloscope 10 can be controlled to be refreshed.
[0045] The auxiliary device 20 includes a switch component 21 and a control component 22. Among them, the auxiliary device 20 generates a trigger signal according to the connection and disconnection of the switch component 21. For example, when the display screen of the oscilloscope 10 is in the refresh state, the trigger signal generated when the switch component 21 is connected or the trigger signal generated when the switch component 21 is disconnected can cause the display screen of the oscilloscope 10 to stop refreshing; when the display screen of the oscilloscope 10 is in the state of stopping refreshing, the trigger signal generated when the switch component 21 is connected or the trigger signal generated when the switch component 21 is disconnected can cause the display screen of the oscilloscope 10 to be refreshed. The switch component 21 can be at least one of a foot switch 211, a voice control switch 212, and a proximity sensor 213.
[0046] For example, when the switch component 21 is a foot switch 211, the connection and disconnection of the switch component 21 are controlled by the user stepping on or treading with the foot. For example, when the user steps on the foot switch 211, the foot switch 211 can be controlled to be connected, and the control component 22 can determine that the switch component 21 is triggered, thereby generating a trigger signal. Or when the user steps on the foot switch 211, the foot switch 211 can be controlled to be disconnected, and the control component 22 can determine that the switch component 21 is triggered, thereby generating a trigger signal. Among them, the foot switch 211 can be divided into two types: mechanical and inductive. The mechanical foot switch 211 works through the traditional gear and rack transmission, while the inductive foot switch 211 works through principles such as electromagnetic induction. It should be noted that a single foot switch 211 can be expanded into multiple foot switches 211, or the binary foot switch 211 can be changed to a multi - base foot switch 211. Or the switch component 21 can be a foot switch 211 that supports analog level adjustment.
[0047] For another example, when the switch component 21 is a voice - controlled switch 212, the voice - controlled switch 212 can be integrated in the oscilloscope 10. The switch component 21 can be a voice - controlled switch component 21 or a voice - controlled switch 212. Among them, the voice - controlled switch component 21 can be an electronic switch component 21 that, in a specific environment, uses sound effects to stimulate the pick - up of the voice - controlled switch component 21 for sound - electricity conversion to control the connection and disconnection of the circuit of the auxiliary device 20, and can automatically disconnect the circuit of the auxiliary device 20 after a delay. The voice - controlled switch 212 can realize the interaction between the user and the auxiliary device 20 by collecting, processing, recognizing, and controlling the user's voice signal. For example, when the user emits the voice "refresh", after the voice - controlled switch 212 obtains the voice "refresh", the voice - controlled switch 212 is triggered, thereby generating a trigger signal, and the oscilloscope 10 can be controlled to refresh the display screen according to the trigger signal; when the user emits the voice "stop", after the voice - controlled switch 212 obtains the voice "stop", the voice - controlled switch 212 is triggered, thereby generating a trigger signal, and the oscilloscope 10 can be controlled to stop refreshing the display screen according to the trigger signal. The voice - controlled switch 212 can be integrated in the oscilloscope 10, or the voice - controlled switch 212 can be connected to the oscilloscope 10 through a data line.
[0048] For another example, when the switch component 21 is a proximity sensor 213, the proximity sensor 213 can be integrated in the oscilloscope 10. By approaching or moving away from the proximity sensor 213 with the user's foot or other body part, the switch component 21 can be triggered. In one embodiment, the proximity sensor 213 can be an optical sensor, such as an infrared induction switch. The infrared sensor can detect changes in infrared radiation within the detection area of the infrared induction switch, and can determine whether the switch component 21 is triggered. When the user's foot or other body part approaches the infrared induction switch component 21, the emitted infrared radiation can be detected by the infrared induction switch component 21, and the control component 22 can determine that the switch component 21 is triggered, thereby generating a trigger signal; or when the user's foot or other body part moves away from the infrared induction switch component 21, the emitted infrared radiation is not detected by the infrared induction switch component 21, and the control component 22 can determine that the switch component 21 is triggered, thereby generating a trigger signal.
[0049] Optionally, in one embodiment, the switch component 21 can be a foot switch 211 and a voice control switch 212; the switch component 21 can be a foot switch 211 and a proximity sensor 213; the switch component 21 can be a voice control switch 212 and a proximity sensor 213, so that the voice control switch 212 and the proximity sensor 213 can be integrated in the oscilloscope 10; or the switch component 21 can be a foot switch 211, a voice control switch 212 and a proximity sensor 213.
[0050] The control component 22 can convert the trigger signal generated when the switch component 21 is triggered into a control instruction, and transmit the control instruction to the oscilloscope 10 for execution by the oscilloscope 10. Among them, the control instruction can be a Standard Commands for Programmable Instruments (SCPI). The control component 22 can be electrically connected to the normally open contact of the switch component 21 through a wire, and the control component 22 can be electrically connected to the data interface 11 of the oscilloscope 10 through a data line. Thus, the trigger signal generated when the switch component 21 is triggered can be transmitted to the control component 22. The control component 22 converts the received trigger signal into a control instruction and then transmits it to the oscilloscope 10. The oscilloscope 10 refreshes the display screen of the oscilloscope 10 according to the control instruction.
[0051] Please refer to Figure 1 and Figure 2 , in some embodiments, the control component 22 includes a switch detector 221 and an instruction converter 222. The switch detector 221 is electrically connected to the switch component 21 and the instruction converter 222; the switch detector 221 is used to detect whether the switch component 21 is triggered, and the instruction converter 222 is used to convert the trigger signal into a control instruction.
[0052] In this way, by providing a switch detector 221 and an instruction converter 222 in the auxiliary device 20, the intention of the user to refresh the screen of the oscilloscope 10 can be converted into a trigger signal for the instruction converter 222, and the instruction converter 222 can generate an instruction capable of controlling the oscilloscope 10 to refresh the screen according to the trigger signal and send it to the oscilloscope 10 for control.
[0053] Specifically, the control component 22 includes a switch detector 221 and an instruction converter 222. Among them, the switch detector 221 can be respectively connected to the switch component 21 and the instruction converter 222. Thus, when the switch component 21 is triggered, it can be detected by the switch detector 221, and the trigger signal is sent to the instruction converter 222.
[0054] The switch detector 221 includes a voltage regulator diode 2211, a first resistor 2212, a second resistor 2213, a third resistor 2214, and a capacitor 2215. Among them, the voltage regulator diode 2211 can be a transient suppression diode, and the voltage regulator diode 2211 can be respectively connected in series with the first resistor 2212, connected in parallel with the second resistor 2213 and the third resistor 2214, and the first resistor 2212, the second resistor 2213, and the third resistor 2214 are connected in series between them, and the capacitor 2215 is connected in parallel with the third resistor 2214.
[0055] For example, when the switch component 21 is a foot switch 211, when the foot switch 211 is not actuated, the foot switch 211 is in an open state, and the voltage across the voltage regulator diode 2211 is determined by the series voltage division of the 5.1 kΩ first resistor 2212, the 1 kΩ second resistor 2213, and the 10 kΩ third resistor 2214 for the 5V voltage, so that the voltage across the voltage regulator diode 2211 is 3.1V. When the instruction converter 222 is powered by 3.3V and the digital signal input port of the instruction converter 222 detects a voltage of 3.1V and exceeds the high level upper limit of 2V, the instruction converter 222 can determine that the switch component 21 is in an open state.
[0056] When the foot switch 211 is depressed for the first time, the two ends of the voltage regulator diode 2211 are short-circuited to 0V by the contacts of the switch component 21, and the 1 μF capacitor 2215 discharges through the 1 kΩ second resistor 2213. After 1 - 2 ms, the voltage detected by the digital signal input port of the instruction converter 222 is lower than the low level lower limit of 0.7V, and the instruction converter 222 determines that the foot switch 211 has been actuated.
[0057] After the foot switch 211 is lifted, the switch assembly 21 is disconnected. The first resistor 2212 with a resistance of 5.1 kΩ and the second resistor 2213 with a resistance of 1 kΩ charge the capacitor 2215 with a capacitance of 1 μF. After 1 - 2 ms, the digital signal input port of the instruction converter 222 detects that the terminal voltage is greater than the upper limit of the 2V high level. The instruction converter 222 determines that the foot switch 211 is disconnected. After confirming the level state through digital filtering, according to the latest instruction issued by the instruction converter 222, it is determined that the oscilloscope 10 should be in the stop refresh state, and this state is written into the register of the control component 22. Moreover, the micro - control unit 2221 regularly sends a query packet to the oscilloscope 10 to confirm the data line connection relationship.
[0058] When the foot switch 211 is pressed down for the second time, the process of detecting the level at the digital signal input port of the instruction converter 222 is repeated. After confirming the level state through digital filtering, the content record of the control instruction issued last time is retrieved. According to the control instruction for stop refresh in the previous record, it is determined that a control instruction for starting refresh should be sent this time. The control instruction for starting refresh is sent to the oscilloscope 10, and the oscilloscope 10 changes from the stop refresh state to the start refresh state. When the foot switch 211 is lifted for the second time, the switch assembly 21 is disconnected, and the process of detecting the level at the digital signal input port of the instruction converter 222 is repeated. After confirming the level state through digital filtering, according to the latest control instruction just issued, it is determined that the oscilloscope 10 should be in the refresh state, and this state is written into the register in the control component 22. Moreover, the micro - control unit 2221 regularly sends a query packet to the oscilloscope 10 to confirm the data line connection relationship.
[0059] When the foot switch 211 is pressed repeatedly, the control instructions sent by the switch detector 221 and the instruction converter 222 to the oscilloscope 10 change cyclically.
[0060] In this way, by setting the voltage - stabilizing diode 2211, resistors, and capacitor 2215 in the switch detector 221, a corresponding trigger signal can be generated according to the change in the level, and a corresponding control instruction can be generated according to the trigger signal.
[0061] The instruction converter 222 can be used to convert the trigger signal generated by the switch component 21 into a control instruction for controlling the operation of the oscilloscope 10. Among them, the instruction converter 222 includes a micro control unit 2221, an Internet protocol address soft core module 2222, a physical address management interface 2223, and a port physical layer 2224. The Internet protocol address soft core module 2222 and the physical address management interface 2223 can be set in the micro control unit 2221. The port physical layer 2224 is electrically connected to the micro control unit 2221 and the oscilloscope 10. Thus, after the trigger signal is transmitted to the micro control unit 2221, the micro control unit 2221 can generate a control instruction. The control instruction can be transmitted to the port physical layer 2224 via the Internet protocol address soft core module 2222 and the physical address management interface 2223, and then the control instruction is transmitted by the port physical layer 2224 to the oscilloscope 10 for execution.
[0062] For example, when the switch component 21 is the foot switch 211, when the foot switch 211 is not actuated, the instruction converter 222 can determine that the switch component 21 is in the off state. Through the Internet protocol address soft core module 2222 and the physical address management interface 2223 built in the control component 222, the micro control unit 2221 is controlled to periodically send a query packet for confirming the network cable connection relationship to the oscilloscope 10.
[0063] For another example, when the foot switch 211 is pressed for the first time, the instruction converter 222 determines that the foot switch 211 is actuated. After confirming the level state through digital filtering, the control instruction for stopping the screen refresh of the oscilloscope 10 is encoded according to the TCP message format and the Internet protocol address inside the oscilloscope 10, and is sent to the oscilloscope 10 after being modulated by the port physical layer 2224. After receiving the instruction, the oscilloscope 10 stops the display refresh.
[0064] For yet another example, after the foot switch 211 is lifted, the switch component 21 is disconnected, the refresh state of the oscilloscope 10 is written into the register of the micro control unit 2221, and a query packet for confirming the data cable connection relationship is periodically sent to the oscilloscope 10.
[0065] In this way, after the trigger signal is transmitted to the instruction converter 222, the micro control unit 2221 can convert the trigger signal into a corresponding control instruction, and then the transmission accuracy to the port physical layer 2224 can be improved through the Internet protocol address soft core module 2222 and the physical address management interface 2223. Finally, it can be directly transmitted to the oscilloscope 10 through the port physical layer 2224, so as to realize the refresh of the display screen of the oscilloscope 10.
[0066] Please refer to Figure 3, in some embodiments, the instruction converter 222 further includes a micro control unit 2221, an Internet protocol address hard core module 2225, a physical address management interface 2223, and a port physical layer 2224. Among them, the Internet protocol address hard core module 2225 and the physical address management interface 2223 can be disposed on the port physical layer 2224, and the port physical layer 2224 is electrically connected to the micro control unit 2221 and the oscilloscope 10. After the trigger signal is transmitted to the micro control unit 2221, a control instruction can be generated via the micro control unit 2221, and the control instruction is transmitted to the port physical layer 2224 via the Internet protocol address hard core module 2225 and the physical address management interface 2223, and then the control instruction is transmitted by the port physical layer 2224 to the oscilloscope 10 for execution.
[0067] For example, in the case where the switch component 21 is the foot switch 211, when the foot switch 211 is not actuated, the instruction converter 222 can determine that the switch component 21 is in the off state, and via the Internet protocol address hard core module 2225 and the physical address management interface 2223 built in the control component 22, control the port physical layer 2224 to periodically send a query packet for confirming the network cable connection relationship to the oscilloscope 10.
[0068] Thus, after the trigger signal is transmitted to the instruction converter 222, the micro control unit 2221 can convert the trigger signal into a corresponding control instruction, and then the transmission accuracy to the port physical layer 2224 can be improved via the Internet protocol address hard core module 2225 and the physical address management interface 2223. Finally, it can be directly transmitted to the oscilloscope 10 through the port physical layer 2224, thereby realizing the refresh of the display screen of the oscilloscope 10.
[0069] Please refer to Figure 4 and Figure 5 , in some embodiments, the switch detector 221 includes a first DIP switch 2216 and at least two second DIP switches 2217. The refresh mode of the oscilloscope 10 is switched according to the conduction and disconnection of the first DIP switch 2216, and the control instruction adapted to the oscilloscope 10 is selected according to the second DIP switch 2217 that is conducted.
[0070] Thus, when the oscilloscope 10 includes different refresh modes, by setting the first DIP switch 2216 in the switch detector 221, the oscilloscope 10 can select the refresh mode according to the DIP generated by the on / off of the first DIP switch 2216.
[0071] Since there are different brands of oscilloscopes 10, their control instructions will also be different. By setting the second DIP switch 2217 corresponding to the brand in the switch detector 221, according to different oscilloscopes 10, the second DIP switch 2217 can generate corresponding DIP codes, so that the instruction converter 222 can send the correct control instructions to the oscilloscope 10 according to different DIP codes.
[0072] Specifically, different refresh modes are set in the oscilloscope 10. Optionally, in one embodiment, the refresh modes include two modes: a refresh / stop refresh switching mode and a single trigger wait / stop refresh mode. Among them, the refresh / stop refresh switching mode means that when the switch component 21 is triggered for the first time, the display screen refresh of the oscilloscope 10 is stopped, and when the switch component 21 is triggered for the second time, the display screen of the oscilloscope 10 is operated to refresh. The single trigger wait / stop refresh mode means that after the switch component 21 is triggered for the first time, when a waveform that meets the requirements appears on the display screen of the oscilloscope 10, the refresh is stopped, and then after the switch component 21 is triggered for the second time, the display screen of the oscilloscope 10 continues to refresh.
[0073] The refresh mode of the oscilloscope 10 can be switched according to specific requirements. Therefore, a first DIP switch 2216 and a fourth resistor 2218 are provided in the switch detector 221. Among them, the first DIP switch 2216 is connected in series with the fourth resistor 2218, and a wire can be led out between the first DIP switch 2216 and the fourth resistor 2218 and connected to the digital input pin of the microcontroller unit 2221. The voltage of the first DIP switch component 21 can be pulled up to 3.3V by the 5.1 kΩ fourth resistor 2218. When the first DIP switch 2216 is open, the digital input pin is pulled up to 3.3V by the 5.1 kΩ fourth resistor 2218, so that the microcontroller unit 2221 can recognize that the first DIP switch 2216 is open, and thus the oscilloscope 10 can execute the control instruction according to the mode corresponding to the open state of the first DIP switch 2216. When the first DIP switch 2216 is closed, the digital input pin is shorted to the 0V of the ground wire by the first DIP switch 2216, and the microcontroller unit 2221 recognizes that the first DIP switch 2216 is closed according to the voltage, so that the oscilloscope 10 can execute the control instruction according to the mode corresponding to the closed state of the first DIP switch 2216.
[0074] Since the control instructions for the same function in oscilloscopes 10 of different brands may not be the same, in order for the oscilloscope 10 to accurately execute the control instructions, a second DIP switch 2217 and a fifth resistor 2219 are provided in the switch detector 221. Among them, the second DIP switch 2217 and the fifth resistor 2219 are connected in series, and a wire can be led out between the second DIP switch 2217 and the fifth resistor 2219 and connected to the digital input pin of the micro control unit 2221. When the second DIP switch 2217 is closed, the DIP code generated by the second DIP switch 2217 is transmitted to the micro control unit 2221. After the micro control unit 2221 recognizes the DIP code, it can generate a control instruction corresponding to the second DIP switch 2217, so that the control instruction can be adapted to the oscilloscope 10 of this brand. It should be noted that multiple second DIP switches 2217 and corresponding resistors can be set according to the number of brands. When the oscilloscope 10 of the corresponding brand is needed, the second DIP switch 2217 corresponding to the brand needs to be closed, and the second DIP switches 2217 corresponding to other brands are disconnected, so that the micro control unit 2221 can generate a control instruction corresponding to the oscilloscope 10.
[0075] Please refer to Figure 6 and Figure 7 Figure 7 , in some embodiments, the auxiliary device 20 includes a power interface 23 for connecting to an external power supply 200 so that the external power supply 200 supplies power to the auxiliary device 20 through the power interface 23.
[0076] In this way, by providing the power interface 23 on the auxiliary device 20, the auxiliary device 20 can be quickly powered by connecting to the external power supply 200 through the power interface 23.
[0077] Specifically, the operation of the auxiliary device 20 requires electrical energy support, so a power interface 23 is provided on the auxiliary device 20, so that the external power supply 200 can supply power to the auxiliary device 20 through the power interface 23. Among them, the power interface 23 is provided on the control component 22. The power interface 23 can be a Universal Serial Bus (USB) interface, and the external power supply 200 can be the oscilloscope 10. The auxiliary device 20 is connected to the oscilloscope 10 through a power supply line, so that the oscilloscope 10 supplies power to the auxiliary device 20. When the power supply interface of the oscilloscope 10 is occupied, the external power supply 200 can be an independent USB adapter, a power bank or a storage battery, etc.
[0078] The power interface 23 can also be detachably connected to an external power supply 200. When the auxiliary device 20 is not needed to assist the oscilloscope 10, the power supply line can be unplugged from the power interface 23. In this way, by detachably connecting the power interface 23 to the external power supply 200, different external power supplies 200 can be adapted. In the case where one external power supply 200 is occupied, the auxiliary device 20 can be connected to other external power supplies 200.
