[0023] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.
[0024] Please refer to Figure 1 , Figure 1 This is a schematic structural diagram of a detection circuit 100 provided in one embodiment of the present application.
[0025] like Figure 1 As shown, the detection circuit 100 includes a main control circuit 10, a fixture drive circuit 20, a first detection circuit 30, a communication circuit 40, and a second detection circuit 50. The fixture drive circuit 20 is connected to the main control circuit 10 and includes a first connection port 21. The first connection port 21 is used to connect to the drive mechanism of the target fixture. The target fixture is used to install the target detection device, and the drive mechanism of the target fixture is used to adjust the detection position of the target detection device. The first detection circuit 30 includes a second connection port, a first connection end, and a second connection end. The first connection end of the first detection circuit 30 is connected to the first power supply, the second connection end of the first detection circuit 30 is connected to the main control circuit 10, and the second connection port of the first detection circuit 30 is used to connect to the driving circuit of the target detection device; the communication circuit 40 is connected to the main control circuit 10, and the communication circuit 40 is used to communicate with the target detection device so as to send the control signal output by the main control circuit 10 to the target detection device; the second detection circuit 50 is also connected to the main control circuit 10, and the second detection circuit 50 is used to receive the electrical signal output by the target detection device, and convert the electrical signal output by the target detection device into a detection signal and output it to the main control circuit 10.
[0026] Exemplarily, the target detection device includes but is not limited to a near-eye display device and components in the near-eye display device, wherein the near-eye display device is a device that can provide augmented reality (AR) technology, or virtual reality (VR) technology, or mixed reality (MR) technology; specifically, the near-eye display device is, for example, AR glasses, and the components in the near-eye display device are, for example, the imaging system in the AR glasses, etc. For ease of understanding, this article takes the target detection device as AR glasses as an example for explanation.
[0027] During the specific implementation process, the AR glasses are installed on the target fixture to fix and adjust the detection position of the AR glasses through the target fixture. Specifically, the fixture driving circuit 20 in the detection circuit 100 transmits a driving signal to the driving mechanism of the target fixture through the first connection port 21 to operate the driving mechanism, thereby adjusting the detection position of the AR glasses.
[0028] During the operation of the driving mechanism, the first detection circuit 30 is used to detect whether the driving mechanism of the target fixture adjusts the AR glasses to the target position. Specifically, the second connection port of the first detection circuit 30 is connected to the driving circuit of the target fixture. After the driving mechanism of the target fixture adjusts the AR glasses to the target position, the driving circuit of the target fixture is turned on, so that the first connection end, the second connection port and the second connection end of the first detection circuit 30 are connected, so that the main control circuit 10 can detect the first voltage provided by the first power supply connected to the first connection end at the second connection end. If the driving mechanism of the target fixture does not adjust the AR glasses to the target position, the driving circuit of the target fixture is turned off, and there is a short circuit between the first connection end, the second connection port and the second connection end of the first detection circuit 30. At this time, the main control circuit 10 cannot detect the first voltage at the second connection end; based on this, the main control circuit 10 determines whether the target fixture adjusts the AR glasses to the target position by detecting the voltage on the second connection end. In a specific implementation process, the second connection port includes two connectors, one connector connects the input end of the target fixture driving circuit 20 to the first connection end of the first detection circuit 30, and the other connector connects the output end of the target fixture driving circuit 20 to the first connection end, so that when the driving circuit is closed and turned on, the voltage signal corresponding to the first voltage provided by the first power supply can reach the second connection end via the first connection end, the connector and the driving circuit, so that the main control circuit 10 can detect the first voltage at the second connection end.
[0029] The main control circuit 10 detects a first voltage at the second connection end of the first detection circuit 30 to determine that the target fixture adjusts the AR glasses to the target position, and then outputs a control signal to the communication circuit 40 so that the communication circuit 40 sends the control signal to the AR glasses. The AR glasses operate according to the control signal to output a corresponding electrical signal. Specifically, for example, the control signal for turning on the optical machine is sent to the AR glasses to turn on the optical machine of the AR glasses and output an optical signal in the optical waveguide of the AR glasses. It should be understood that the light emitted from the optical machine of the AR glasses can be incident on the optical waveguide and emitted to the outside of the optical waveguide after directional transmission of the optical waveguide, so that the optical signal can be collected at the position where the light is emitted from the optical waveguide.
[0030] When the AR glasses output electrical signals, the second detection circuit 50 can collect the electrical signals output by the AR glasses and convert the collected electrical signals into detection signals for transmission to the main control circuit 10, so that the main control circuit 10 determines the detection status of the AR glasses based on the detection signals, and thus completes the detection of the AR glasses.
[0031] By integrating the fixture driving circuit 20, the first detection circuit 30, the communication circuit 40 and the second detection circuit 50 on the detection circuit 100, the target fixture on which the target detection device is installed can be controlled so that the target fixture adjusts the target detection device to the target position and provides the target detection device with the required detection conditions. After the first detection circuit 30 detects that the target fixture adjusts the target detection device to the target position, a control signal is sent to the target detection device through the communication circuit 40 to control the operating status of the target detection device. Finally, the second detection device is used to detect the operating status of the target detection device to complete the detection of the target detection device. Therefore, there is no need to set up independent control devices to control the target fixture and the target detection device respectively, which can realize the automation of the detection process, simplify the detection system, and reduce the maintenance difficulty and maintenance cost of the detection system.
[0032] See also Figure 2 , Figure 2 This is a schematic structural diagram of a detection circuit 100 provided in one embodiment of the present application.
[0033] In some embodiments, the second detection circuit 50 includes a first detection unit 51 and a second detection unit 52. The first detection unit 51 is connected to the main control circuit 10 and includes a photoresistor R1. The photoresistor R1 is used to receive the light signal output by the target detection device, and the resistance value of the photoresistor R1 changes with the intensity of the light signal output by the target detection device, so that the signal strength of the first detection signal output by the first detection unit 51 to the main control circuit 10 changes with the intensity of the light signal. The second detection unit 52 is connected to the main control circuit 10 and includes a sound receiving component. The sound receiving component is used to receive the audio signal output by the target detection device, and the resistance value of the sound receiving component changes with the intensity of the audio signal output by the target detection device, so that the signal strength of the second detection signal output by the second detection unit 52 to the main control circuit 10 changes with the intensity of the audio signal.
[0034] Exemplarily, the first detection unit 51 includes a photoresistor R1. Light emitted from a target detection device, such as AR glasses, can illuminate the photoresistor R1 in the first detection unit 51, so that the photoresistor R1 collects a light signal. It should be understood that the resistance value of the photosensitive circuit will change with the brightness of the irradiated light, that is, it will change with the signal strength of the light signal, so that the signal strength of the first detection signal output by the first detection unit 51 to the main control circuit 10 changes with the signal strength of the light signal, and then the main control circuit 10 detects the signal strength of the light signal to determine the brightness of the light output by the AR glasses, thereby realizing the detection of the light output by the target detection device.
[0035] Exemplarily, the second detection unit 52 includes a sound receiving component, which is used to collect the audio signal output from the target detection device, and the resistance value of the sound receiving component will also change with the signal strength of the audio signal, so that the second detection signal output by the second detection unit 52 to the main control circuit 10 will also change accordingly, thereby enabling the main control circuit 10 to detect the signal strength of the audio signal to determine whether the target detection device outputs audio and the volume of the output audio, thereby realizing the detection of the audio output of the target detection device.
[0036] In a specific implementation process, after the main control circuit 10 detects the first voltage at the second connection terminal of the first detection circuit 30, it outputs a first control signal and / or a second control signal to the communication circuit 40, so that the communication circuit 40 sends the first control signal and / or the second control signal to the target detection device, so that the target detection device outputs an optical signal according to the first control signal and / or outputs an audio signal according to the second control signal; the main control circuit 10 collects an optical signal through the first detection unit 51 in the second detection circuit 50 to determine whether the target detection device outputs an optical signal or the signal strength of the output optical signal after receiving the first control signal; and collects an audio signal through the second detection unit 52 to determine whether the target detection device outputs an audio signal or the signal strength of the output audio signal, thereby realizing detection of the target detection device. It should be understood that if no optical signal or audio signal is detected, it can be determined that the target detection device has failed the detection. It should be noted that in other embodiments, it can also be set that the target detection device has failed the detection when the signal strength of the detected optical signal and / or audio signal is less than or equal to a preset signal strength threshold. This application does not limit the specific detection pass conditions, and those skilled in the art can set the detection pass conditions according to actual needs.
[0037] Please continue reading Figure 2 In some embodiments, the first detection unit 51 further includes a first resistor R2; a first end of the first resistor R2 is connected to the first power supply, a second end of the first resistor R2 is connected to a first end of the photoresistor R1, the second end of the first resistor R2 is also connected to the main control circuit 10, and a second end of the photoresistor R1 is grounded.
[0038] For example, the first resistor R2 and the photoresistor R1 act as a voltage divider. When the resistance value of the photoresistor R1 changes, the voltage at the second end of the first resistor R2 will also change accordingly, thereby enabling the main control circuit 10 to detect the first detection signal with different signal sizes to complete the detection of the output light of the target detection device.
[0039] Please continue reading Figure 2In some embodiments, the second detection unit 52 further includes a second resistor R3, a third resistor R4, a fourth resistor R5, a fifth resistor R6, a first capacitor C1, a second capacitor C2, and a switch tube Q1; the negative interface of the sound receiving component 521 is connected to the first end of the first capacitor C1, and the second end of the first capacitor C1 is connected to the input end of the switch tube Q1 through the second resistor R3; the input end of the switch tube Q1 is also connected to the first power supply through the third resistor R4, and the input end of the switch tube Q1 is also connected to the main control circuit 10; the negative interface of the sound receiving component 521 is also connected to the first end of the fourth resistor R5, the second end of the fourth resistor R5 is connected to the first power supply through the fifth resistor R6, and the second end of the fourth resistor R5 is also connected to the first end of the second capacitor C2; the second end of the second capacitor C2, the output end of the switch tube Q1, and the positive interface of the sound receiving component 521 are all grounded.
[0040] It should be understood that when the sound receiving component 521 collects an audio signal, the resistance value of the sound receiving component 521 will change, but it can only cause a slight current change in the first detection unit. Therefore, a transistor is set in the second detection unit 52 so that the transistor amplifies the current in the second detection unit 52 to amplify the signal in the second detection unit 52, thereby enabling the main control circuit 10 to detect the corresponding second detection signal, so as to determine the audio output status of the target detection device according to the second detection signal, and complete the detection of the audio output of the target detection device.
[0041] In some embodiments, the second detection circuit 50 includes two first detection units 51 and two second detection units 52 , and different detection units are connected to different detection terminals of the main control circuit 10 .
[0042] Exemplarily, the second detection circuit 50 is provided with two first detection units 51 and two second detection units 52 to collect signals from the output positions of two optical signals and the output positions of two audio signals on the target detection device. And different detection units are connected to different detection ends of the main control circuit 10, so that the main control circuit 10 can respectively determine the optical signals or audio signals at each output position. Taking AR glasses as an example, optical signals are output from two lenses respectively, and the first detection unit 51 corresponds to the lenses one by one to collect the optical signals output from each lens; similarly, audio signals are output from the temples on both sides, and the audio signals output from each temple on each side are collected by two detection units respectively to complete the collection of optical and audio signals of AR glasses, thereby improving the completeness and convenience of AR glasses detection.
[0043] In other embodiments, the second detection circuit 50 may further be provided with more first detection units 51 and more second detection units 52 to detect one or more target detection devices, thereby improving the efficiency of device detection.
[0044] See also Figure 3, Figure 3 This is a schematic structural diagram of a detection circuit 100 provided in one embodiment of the present application.
[0045] In some embodiments, the fixture driving circuit 20 also includes a relay KJ, an anti-reverse component D1, a current limiting resistor R7 and a light-emitting diode D2; the first pin of the relay KJ is connected to the main control circuit 10 and the negative pole of the anti-reverse component D1, and the first pin of the relay KJ is also connected to the positive pole of the light-emitting diode D2 through the current limiting resistor R7; the third pin of the relay KJ is connected to the first connection port 21, and the fourth pin of the relay KJ is connected to the second power supply; the seventh pin of the relay KJ, the eighth pin of the relay KJ, the positive pole of the anti-reverse component D1 and the negative pole of the light-emitting diode D2 are all grounded.
[0046] For example, the main control circuit 10 outputs a signal for driving the target fixture to the relay KJ, which then outputs the drive signal to the first connection port 21 via the relay KJ, thereby transmitting the drive signal to the target fixture to control the drive mechanism of the target fixture via the drive signal. In a specific implementation, when the fixture drive circuit 20 outputs the drive signal, the light-emitting diode D2 illuminates to indicate that the fixture drive circuit 20 is outputting the drive signal. Therefore, if the fixture drive circuit 20 is outputting the drive signal but the drive mechanism is not operating, it can be determined that there is a problem with the drive mechanism or the wires connecting the drive mechanism, thereby reducing the maintenance difficulty and cost of the detection system.
[0047] See also Figure 4 , Figure 4 This is a schematic structural diagram of a detection circuit 100 provided in another embodiment of the present application.
[0048] In some embodiments, the detection circuit 100 also includes a voltage conversion circuit 60, which is connected to the first detection circuit 30 and the second detection circuit 50; the voltage conversion circuit 60 is used to convert the second voltage provided by the second power supply into the first voltage provided by the first power supply, so that the detection circuit 100 operates under the drive of the first voltage provided by the first power supply.
[0049] Exemplarily, a voltage conversion circuit 60 is also provided in the detection circuit 100, and the voltage conversion circuit 60 is also connected to the main control circuit 10. The voltage conversion circuit 60 converts the second voltage provided by the second power supply into a first voltage to provide the required working voltage for the detection circuit 100. That is, in each of the above-mentioned embodiments connected to the first power supply, the voltage conversion circuit 60 can be connected to provide the first voltage to the corresponding circuit through the voltage conversion circuit 60. For example, the first connection end of the first detection circuit 30 is connected to the voltage conversion circuit 60, so that the voltage conversion circuit 60 applies the first voltage to the first connection end of the first detection circuit 30 to achieve the same effect as connecting the first power supply.
[0050] It should be understood that the present application does not limit the specific structure of the voltage conversion circuit 60 , and any circuit that can convert the input second voltage into the first voltage and output it can serve as the voltage conversion circuit 60 .
[0051] Specifically, the second voltage is 12V and the first voltage is 5V.
[0052] Exemplarily, a light-emitting element is also provided in the voltage conversion circuit 60 to indicate the working status of the voltage conversion circuit 60 .
[0053] Exemplarily, the voltage conversion circuit 60 also includes a third connection port, which is used to connect to the target detection device. The voltage conversion circuit 60 can also provide a first voltage to the circuit in the target detection device through the third connection port to enable the target detection device to operate and output an electrical signal.
[0054] It should be noted that by setting a voltage conversion circuit 60 in the detection circuit 100, the number of power supplies can be reduced. Only one power supply that outputs a second voltage is required to meet the usage requirements of the first voltage and the second voltage in the detection circuit 100, thereby simplifying the detection system.
[0055] In some embodiments, the communication circuit 40 includes a Bluetooth module, which is connected to the main control circuit 10 and is used to send the control signal output by the main control circuit 10 to the target detection device.
[0056] Exemplarily, the communication circuit 40 includes a Bluetooth module, and the Bluetooth module is connected to the main control circuit 10 so as to send the control signal output by the main control circuit 10 to the target detection device to control the target detection device, and can also test the Bluetooth module on the target detection device.
[0057] In other embodiments, the communication circuit 40 may further include a fourth connection port for connecting to a target detection device via the fourth connection port, thereby transmitting a control signal to the target detection device via the fourth connection port. Alternatively, the communication circuit 40 may include a Bluetooth module and a fourth connection port, so that testers can select a communication method based on actual needs, thereby improving the applicability of the detection circuit 100.
[0058] The detection circuit 100 provided in the above embodiment can control the target fixture through the fixture driving circuit 20 so that the target fixture adjusts the target detection device to the target position for detection, and detects whether the target fixture adjusts the target detection device to the target position through the first detection circuit 30. After the main control circuit 10 determines that the target fixture adjusts the target detection device to the target position, the control signal output by the main control circuit 10 is sent to the target detection device through the communication circuit 40 to enable the target detection device to operate, thereby realizing control of the target detection device, and when the target detection device operates and outputs a corresponding electrical signal, the electrical signal output by the target detection device is collected through the second detection circuit 50 to complete the detection of the target detection device. There is no need to control the target fixture and the target detection device separately through independent control devices, and a detection environment that meets the detection requirements is provided for the target detection device, so as to simplify the detection system and reduce the maintenance cost and difficulty of the detection system.

In a specific embodiment, the detection device also includes a housing, and at least a portion of the detection circuit 100 is located within the housing.

In other embodiments, the detection device may also be powered by an external power supply. This application does not limit the specific components or circuits included in the detection device.

The target fixture can be mounted with the target detection device and can adjust the detection position of the target detection device. The detection device can control the target fixture to adjust the target detection device to the target position. When the target detection device is at the target position, the detection device also outputs a control signal to control the target detection device to operate and output a corresponding electrical signal. The detection device detects the target detection device by collecting the electrical signal output by the target detection device.
