[0002] In the related art, near-eye display devices need to undergo factory inspection. When performing factory inspection on near-eye display devices, it is necessary to involve the use, power on and off, disassembly, etc. of the preset components of the near-eye display devices, which may easily cause damage to the preset components. Based on this, it is necessary to monitor the number of times the preset components are used. When monitoring the number of times the preset components are used, software monitoring is generally used to monitor the number of times the preset components are used.

Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.

[0019] 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 in the embodiments may be combined with each other.

[0020] See also Figure 1 , Figure 1 A schematic structural diagram of a number monitoring module 100 provided in an embodiment of the present application. Exemplarily, the number monitoring module 100 can be applied to a test device 200, which is used to test a near-eye display device 300. The near-eye display device 300 may include an extended reality (XR) device. XR devices may include augmented reality (AR) glasses, virtual reality (VR) glasses, mixed reality (MR) glasses, AR helmets, VR helmets, MR helmets, etc., without limitation herein.

[0021] like Figure 1As shown, the number monitoring module 100 includes: a first detection module 110, the input end of the first detection module 110 is used to connect to the test device 200, and the output end of the first detection module 110 is used to connect to the preset device 310 of the near-eye display device 300; the input end of the first detection module 110 connects or disconnects the first detection module 110 and the preset device 310 according to the first control electrical signal output by the test device 200, and the output end of the first detection module 110 outputs a first level signal as a high level signal when the first detection module 110 and the preset device 310 are connected, and outputs a first level signal as a low level signal when the first detection module 110 and the preset device 310 are disconnected; a counting module 120, the counting module 120 is connected to the output end of the first detection module 110; the counting module 120 is used to record the number of times the preset device 310 is used plus one when the first level signal switches from a low level signal to a high level signal.

[0022] For example, the input end of the first detection module 110 can connect or disconnect the first detection module 110 and the preset device 310 according to the received first control electrical signal.

[0023] When the first detection module 110 is connected to the preset device 310, a corresponding connection relationship is established between the test device 200 and the first detection module 110, and between the first detection module 110 and the preset device 310. Thus, a corresponding connection relationship can be established between the test device 200 and the preset device 310, which is equivalent to the test device 200 and the preset device 310 being connected. Based on the connection relationship between the test device 200 and the preset device 310, the test device 200 can test the near-eye display device 300 by calling the preset device 310. Accordingly, when the test device 200 calls the preset device 310, since the first detection module 110 and the preset device 310 are connected, the first level signal output by the output terminal of the first detection module 110 is a high level signal.

[0024] When the first detection module 110 and the preset device 310 are disconnected, it is equivalent to not having a corresponding connection relationship between the first detection module 110 and the preset device 310. Therefore, the test device 200 cannot establish a corresponding connection relationship with the preset device 310. Therefore, the test device 200 cannot call the preset device 310. Accordingly, when the test device 200 calls the preset device 310, because the first detection module 110 and the preset device 310 are disconnected, the first level signal outputted by the output terminal of the first detection module 110 is a low-level signal.

[0025] For example, the counting module 120 can record the first level signal output from the output end of the first detection module 110 based on the connection relationship with the output end of the first detection module 110. Accordingly, when the first level signal switches from a low level signal to a high level signal, it can be determined that the first detection module 110 and the preset device 310 are switched from a disconnected state to a connected state. The testing device 200 can call the preset device 310 through the first detection module 110 in a connected state, and the counting module 120 can record the number of times the preset device 310 is used plus one. When the counting module 120 records the number of times the preset device 310 is used, it is beneficial to improve the convenience and monitoring effect of the number monitoring module 100 in monitoring the number of times the preset device 310 is used.

[0026] In some embodiments, the first detection module 110 includes a relay 111, the input end of the relay 111 is used to connect to the test device 200, and the output end of the relay 111 is used to connect to the preset device 310 and the counting module 120; the input end of the relay 111 connects or disconnects the relay 111 and the preset device 310 according to the first control electrical signal output by the test device 200; the output end of the relay 111 outputs a first level signal as a high level signal when the relay 111 and the preset device 310 are connected, and outputs a first level signal as a low level signal when the relay 111 and the preset device 310 are disconnected.

[0027] like Figure 2 As shown, the connection state between the input end of relay 111 and the output end of relay 111 can be switched to a closed state or an open state. When the output end of relay 111 is used to connect to the test device 200, and the output end of relay 111 is used to connect to the preset device 310, relay 111 can switch the connection state between the input end of relay 111 and the output end of relay 111 to a closed state or an open state based on the first control electrical signal output by the test device 200. When the connection state is the closed state, relay 111 and preset device 310 are connected. When the connection state is the open state, relay 111 and preset device 310 are disconnected.

[0028] Taking the example of a case where the first control electrical signal is a high-level signal and the connection between the input terminal of relay 111 and the output terminal of relay 111 is disconnected, if the test device 200 needs to call the preset device 310, the test device 200 can output a high-level signal. When the input terminal of relay 111 receives the high-level signal output by the test device 200, relay 111 can, driven by the high-level signal, control the connection between the input terminal of relay 111 and the output terminal of relay 111 to switch from an open state to a closed state, thereby connecting relay 111 to the preset device 310.

[0029] Of course, this is not limited to the above. For example, the first control electrical signal is a low-level signal, and the connection state between the input end of the relay 111 and the output end of the relay 111 is in a closed state. When the test device 200 completes the call to the preset device 310, the test device 200 can output a low-level signal. When the input end of the relay 111 receives the low-level signal output by the test device 200, the relay 111 can, under the action of the low-level signal, control the input end of the relay 111 and the output end of the relay 111 to switch from a closed state to an open state, thereby disconnecting the relay 111 from the preset device 310. This is not limited to the above.

[0030] Accordingly, when the connection between the input terminal of the relay 111 and the output terminal of the relay 111 is in a closed state, each adjacent two of the test device 200, the relay 111, and the preset device 310 are in a conductive state, and the first level signal output by the output terminal of the relay 111 is a high-level signal. When the input terminal of the relay 111 and the output terminal of the relay 111 are disconnected, each adjacent two of the test device 200, the relay 111, and the preset device 310 are in an open-circuit state, and the first level signal output by the output terminal of the relay 111 is a low-level signal.

[0031] The first level signal can be used by the counting module 120 to record the number of times the preset device 310 is used.

[0032] In some embodiments, the frequency monitoring module 100 further includes a control module 130 .

[0033] like Figure 3 As shown, the input of the control module 130 is connected to the counting module 120, and the output of the control module 130 is connected to the input of the first detection module 110. When the number of uses recorded by the counting module 120 reaches a preset threshold, the output of the control module 130 outputs a second control electrical signal; and the input of the first detection module 110 disconnects the first detection module 110 from the preset device 310 based on the second control electrical signal output by the control module 130.

[0034] For example, the preset device 310 includes a consumable part of the near-eye display device 300. As the number of times the preset device 310 is used increases, the preset device 310 is easily damaged. Based on this, when the counting module 120 records the number of times the preset device 310 is used, the counting module 120 can transmit the number of times the preset device 310 is used to the control module 130 based on the connection relationship with the input end of the control module 130. The output end of the control module 130 can output a second control electrical signal in response to the received number of uses reaching a preset number threshold. The second control electrical signal is used to instruct the first detection module 110 and the preset device 310 to be disconnected to limit the increase in the number of uses of the preset device 310. Accordingly, the first detection module 110 can disconnect the first detection module 110 and the preset device 310 in response to the received second control electrical signal.

[0035] In this way, by limiting the number of times the preset device 310 is used, the control module 130 is helpful to reduce the loss of the preset device 310 caused by the testing device 200 when testing the near-eye display device 300, and improve the convenience and effect of monitoring the number of times the preset device 310 is used.

[0036] In some embodiments, the number monitoring module 100 also includes an AC / DC conversion module 140; the input end of the AC / DC conversion module 140 is connected to the AC power supply and the counting module 120, and the output end of the AC / DC conversion module 140 is grounded; the input end of the AC / DC conversion module 140 outputs the second level signal as a high level signal when the AC power supply is in a power supply state, and outputs the second level signal as a low level signal when the AC power supply is in a non-power supply state; the counting module 120 is used to record the number of power-on times of the preset device 310 plus one when the second level signal switches from a low level signal to a high level signal, or to record the number of power-off times of the preset device 310 plus one when the second level signal switches from a high level signal to a low level signal.

[0037] For example, when the input end of the AC / DC conversion module 140 is connected to an AC power source and the output end of the AC / DC conversion module 140 is grounded, the AC / DC conversion module 140 can convert the alternating current (AC) provided by the AC power source into direct current (DC). When the AC power source is in a power supply state, that is, the AC power source is supplying power to the AC / DC conversion module 140, the second level signal output from the input end of the AC / DC conversion module 140 is a high level signal. When the AC power source is in a non-power supply state, that is, the AC power source is not supplying power to the AC / DC conversion module 140, the second level signal output from the input end of the AC / DC conversion module 140 is a low level signal.

[0038] Accordingly, when the AC power supply is in a powered state, the times monitoring module 100 may be in a powered state. The AC power supply can then supply power to the preset device 310 through the connection between the times monitoring module 100 and the preset device 310, such as when the first detection module 110 and the preset device 310 are connected. When the AC power supply supplies power to the preset device 310, the preset device 310 is in a powered state. When the AC power supply is in a non-powered state, the times monitoring module 100 may be in a non-powered state. The preset device 310, which has established a connection with the times monitoring module 100, is also in a non-powered state. The preset device 310 being in a powered state or a non-charging state allows the counting module 120 to determine at least one of the number of times the preset device 310 is powered on or powered off.

[0039] For example, the counting module 120 can record the second level signal output from the input end of the AC / DC conversion module 140 based on the connection relationship with the input end of the AC / DC conversion module 140. For example, when the second level signal switches from a low level signal to a high level signal, it can be determined that the AC power supply switches from a non-powered state to a powered state. Correspondingly, when the AC power supply switches from a non-powered state to a powered state, the number monitoring module 100 can switch from a non-powered state to a powered state, and the preset device 310 that has a connection relationship with the number monitoring module 100 can also switch from a non-powered state to a powered state, then the counting module 120 can record the number of power-ons of the preset device 310 plus one. For another example, when the second level signal switches from a high level signal to a low level signal, it can be determined that the AC power supply switches from a powered state to a non-powered state. Accordingly, when the AC power source switches from a powered state to a non-powered state, the times monitoring module 100 can switch from a powered state to a non-powered state, and the preset device 310 connected to the times monitoring module 100 can also switch from a powered state to a non-powered state. The counting module 120 can then record the number of power-off times of the preset device 310 plus one. When the counting module 120 records at least one of the power-on times and the power-off times of the preset device 310, this facilitates improving the convenience and effectiveness of monitoring the at least one of the power-on times and the power-off times of the preset device 310 by the times monitoring module 100.

[0040] In some embodiments, the AC / DC conversion module 140 includes a mutual inductance coil 141, a first end of the mutual inductance coil 141 is connected to the AC power supply and the counting module 120, and a second end of the mutual inductance coil 141 is grounded; the first end of the mutual inductance coil 141 outputs a second level signal as a high level signal when the AC power supply is in a power supply state, and outputs a second level signal as a low level signal when the AC power supply is in a non-power supply state.

[0041] For example, the number monitoring module 100 may set the first end of the mutual inductance coil 141 as the input end of the AC / DC conversion module 140 , and set the second end of the mutual inductance coil 141 as the output end of the AC / DC conversion module 140 .

[0042] like Figure 4 As shown, the first end of the mutual inductance coil 141 can be connected to the AC power supply and the counting module 120, and the second end of the mutual inductance coil 141 can be grounded. When the AC power supply is in a power supply state, for example, the AC power supply can provide 220V AC power to the first end of the mutual inductance coil 141. The mutual inductance coil 141 can then perform AC / DC conversion on the AC power provided by the AC power supply to generate corresponding DC power. Based on the connection relationship with the preset device 310, the number monitoring module 100 can provide DC power to the preset device 310. In this case, the second level signal output by the first end of the mutual inductance coil 141 is a high level signal.

[0043] Accordingly, when the AC power source is in a non-powered state, the AC power source does not provide AC power to mutual induction coil 141, and mutual induction coil 141 does not need to perform AC / DC conversion on the AC power. The number monitoring module 100 is unable to provide DC power to the preset device 310 based on its connection with the preset device 310, and the second level signal output by the first end of mutual induction coil 141 is a low-level signal.

[0044] The counting module 120 may be connected to the first end of the mutual inductance coil 141 , and the second level signal may be used by the counting module 120 to record the number of power-on times or power-off times of the preset device 310 .

[0045] In some embodiments, the number monitoring module 100 also includes a second detection module 150; the first end of the second detection module 150 is used to connect the preset device 310 and the counting module 120, the second end of the second detection module 150 is grounded, and the third end of the second detection module 150 is connected to a DC power supply; the first end of the second detection module 150 connects the first end of the second detection module 150 and the second end of the second detection module 150 when the second detection module 150 and the preset device 310 are in a connected state, and connects the first end of the second detection module 150 and the second end of the second detection module 150 when the second detection module 150 and the preset device 310 are in a disconnected state; the first end of the second detection module 150 outputs a third level signal as a low level signal when the first end of the second detection module 150 and the second end of the second detection module 150 are connected, and outputs a third level signal as a high level signal when the first end of the second detection module 150 and the third end of the second detection module 150 are connected; the counting module 120 is used to record the number of times the preset device 310 is disassembled plus one when the third level signal switches from a low level signal to a high level signal.

[0046] For example, when the first end of the second detection module 150 is connected to the preset device 310, the second end of the second detection module 150 is grounded, and the third end of the second detection module 150 is connected to a DC power supply, the first end of the second detection module 150 can switch between the first end of the second detection module 150 and the second end of the second detection module 150 or the third end of the second detection module 150 in response to a change in the connection state with the preset device 310. For example, when the first end of the second detection module 150 is connected to the preset device 310, the first end of the second detection module 150 and the second end of the second detection module 150 can be in a closed state, so that the first end of the second detection module 150 is in communication with the second end of the second detection module 150. When the second end of the second detection module 150 is grounded, the third level signal output by the first end of the second detection module 150 can be a low level signal. When the third level signal is a low level signal, the third level signal can be used to indicate that the number monitoring module 100 has established a connection relationship with the preset device 310. For another example, when the first end of the second detection module 150 and the preset device 310 are not connected, the first end of the second detection module 150 and the third end of the second detection module 150 can be in a closed state, so that the first end of the second detection module 150 and the third end of the second detection module 150 are connected. If the third end of the second detection module 150 is connected to a DC power supply, since the DC power supply can provide corresponding DC power to the second detection module 150, the third level signal output by the first end of the second detection module 150 can be a high level signal. When the third level signal is a high level signal, the third level signal can be used to indicate that the number monitoring module 100 and the preset device 310 are not connected.

[0047] The third level signal may be used by the counting module 120 to record the number of times the preset device 310 is disassembled.

[0048] For example, the counting module 120 can record the number of times the preset device 310 has been disassembled based on changes in the third level signal. For example, when the third level signal switches from a high level signal to a low level signal, it can be determined that the second detection module 150 and the preset device 310 have switched from a disconnected state to a disconnected state. Accordingly, the counting module 120 can determine that the number of monitoring modules 100 and the preset device 310 have re-established a connection relationship, thereby determining that the preset device 310 has not been disassembled, and there is no need to record the number of times the preset device 310 has been disassembled. For another example, when the third level signal switches from a low level signal to a high level signal, it can be determined that the second detection module 150 and the preset device 310 have switched from a connected state to a disconnected state. Accordingly, the counting module 120 can determine that the number of monitoring modules 100 and the preset device 310 are no longer connected, thereby determining that the preset device 310 has been disassembled, and record the number of times the preset device 310 has been disassembled, which is incremented by one. When the counting module 120 records the number of times the preset device 310 is disassembled, it is beneficial to improve the convenience and monitoring effect of the number monitoring module 100 in monitoring the number of times the preset device 310 is disassembled.

[0049] In some embodiments, the second detection module 150 includes a limit switch 151, the first end of the limit switch 151 is used to connect the preset device 310 and the counting module 120, the second end of the limit switch 151 is grounded, and the third end of the limit switch 151 is connected to a DC power supply; the first end of the limit switch 151 connects the first end of the limit switch 151 and the second end of the limit switch 151 when the limit switch 151 and the preset device 310 are in a connected state, and connects the first end of the limit switch 151 and the third end of the limit switch 151 when the limit switch 151 and the preset device 310 are in a disconnected state; the first end of the limit switch 151 outputs a third level signal as a low level signal when the first end of the limit switch 151 is connected to the second end of the limit switch 151, and outputs a third level signal as a high level signal when the first end of the limit switch 151 is connected to the third end of the limit switch 151.

[0050] For example, the number monitoring module 100 can set the first end of the limit switch 151 as the first end of the second detection module 150, the second end of the limit switch 151 as the second end of the second detection module 150, and the third end of the limit switch 151 as the third end of the second detection module 150.

[0051] like Figure 5As shown, the first end of the limit switch 151 can be used to connect to the preset device 310, the second end of the limit switch 151 is grounded, and the third end of the limit switch 151 is connected to a DC power supply. The DC power supply can, for example, provide 3.3V DC power to the third end of the limit switch 151, which is not limited here. The first end of the limit switch 151 can switch the first end of the limit switch 151 and the second end of the limit switch 151 to a closed state based on the connection state with the preset device 310. Since the second end of the limit switch 151 is grounded, the third level signal output by the first end of the limit switch 151 is a low level signal. The first end of the limit switch 151 can also switch the first end of the limit switch 151 and the third end of the limit switch 151 to a closed state based on the disconnection state with the preset device 310. Since the third end of the limit switch 151 is connected to the DC power supply, the third level signal output by the first end of the limit switch 151 is a high level signal.

[0052] The counting module 120 may be connected to the first end of the travel switch 151 , and the third level signal may be used by the counting module 120 to record the number of times the preset device 310 is disassembled.

[0053] For example, the preset device 310 comprises a consumable part of the near-eye display device 300. As the preset device 310 is used, powered on, powered off, or disassembled, it may be easily damaged, thereby resulting in poor testing results of the near-eye display device 300 by the testing apparatus 200. To address this issue, a times monitoring module can be used to monitor the number of times the preset device 310 is used, powered on, powered off, or disassembled.

[0054] In some embodiments, the output end of the first detection module 110 is used to connect to one or more preset devices 310 , and the multiple preset devices 310 are set on one or more near-eye display devices 300 .

[0055] For example, when testing the near-eye display device 300, the testing device 200 can test one or more preset components 310 of the near-eye display device 300. Accordingly, the frequency monitoring module 100 needs to monitor at least one of the following: the number of times the one or more preset components 310 have been used, the number of times they have been powered on, the number of times they have been powered off, and the number of times they have been disassembled. Based on this, the frequency monitoring module 100 can be connected to one or more preset components 310 of the same near-eye display device 300 via the output end of the first detection module 110 to monitor the one or more preset components 310.

[0056] For example, the testing device 200 can also test multiple near-eye display devices 300 simultaneously. Accordingly, when the multiple near-eye display devices 300 are respectively provided with one or more preset devices 310, the frequency monitoring module 100 needs to monitor at least one of the usage count, power-on count, power-off count, and disassembly count of the one or more preset devices 310 of each of the multiple near-eye display devices 300. Based on this, the frequency monitoring module 100 can be connected to the one or more preset devices 310 of each of the multiple near-eye display devices 300 through the output end of the first detection module 110 to realize monitoring of the one or more preset devices 310.

[0057] Of course, this is not limited to the foregoing. For example, the number monitoring module 100 may include multiple first detection modules 110, the input ends of the multiple first detection modules 110 are respectively connected to the test device 200, and the output ends of the multiple first detection modules 110 are respectively connected to one of the preset devices 310, so as to monitor the number of times one or more preset devices 310 have been used. For another example, the number monitoring module 100 may include multiple second detection modules 150, the first ends of the multiple second detection modules 150 are respectively connected to one of the preset devices 310, so as to monitor the number of times one or more preset devices 310 have been disassembled.

[0058] When the number monitoring module 100 monitors at least one of the usage count, power-on count, power-off count, and disassembly count of one or more preset components 310 , it is beneficial to improve the comprehensiveness of the number monitoring module 100's monitoring of the number of preset components 310 .

[0059] In some embodiments, the preset device 310 includes at least one of a preset snap-fit device, a preset burning device, a photometer, and a test probe of the near-eye display device 300 .

[0060] The preset fastening device includes, for example, a flexible printed circuit (FPC) fastening device or a fastening device made of other materials. When using the preset fastening device, if the preset fastening device is operated with excessive force or in an improper direction, it is easy to cause damage to the preset fastening device. Accordingly, as the number of times the preset fastening device is used increases, the possibility of damage to the preset fastening device also increases. Based on this, the preset fastening device can be connected to the output end of the first detection module 110 of the number of times monitoring module 100, so that the connection status of the test device 200 and the preset fastening device can be controlled by the first detection module 110, and the number of times the preset fastening device is used can be recorded by the counting module 120 of the number of times monitoring module 100, so as to subsequently limit the number of times the test device 200 uses the preset fastening device. For example, the number of times monitoring module 100 can limit the use of the preset fastening device through the control module 130 if the number of uses reaches a preset number threshold. Of course, it is not limited to the preset fastening device. The preset device 310 can also include other consumable parts with a limited number of uses, which are not limited here. During the process of testing the near-eye display device 300 by the testing device 200, if the possibility of damage to the preset burner, photometer and test probe increases with the number of tests of the testing device 200, the preset burner, photometer and test probe can also be connected separately through the first detection module 110 to facilitate the subsequent use of the preset burner, photometer and test probe. No restriction is made here.

[0061] For example, the likelihood of damage to a preset device 310, such as a preset programmer, is likely to increase with an increase in at least one of the number of power-on cycles and the number of power-off cycles. The preset programmer may include, for example, a Loda programmer, without limitation. During testing of the preset programmer provided on the near-eye display device 300 by the testing device 200, if an unexpected power outage occurs, the preset programmer may be damaged. Based on this, the AC / DC conversion module 140 of the number monitoring module 100 can monitor the power-on and power-off status of the preset programmer. Accordingly, the counting module 120 can record at least one of the number of power-on cycles and the number of power-off cycles of the preset programmer in response to monitoring information, such as a second level signal, from the AC / DC conversion module 140 regarding the power-on and power-off status of the preset programmer. For example, the counting module 120 of the number monitoring module 100 can record at least one of the number of power-on cycles and the number of power-off cycles of the preset programmer based on the second level signal outputted from the input terminal of the AC / DC conversion module 140. The number of times the preset programmer has been powered on, as recorded by the counting module 120, can be used to subsequently monitor the number of times the preset programmer has been powered on. Correspondingly, the number of times the preset programmer has been powered off, as recorded by the counting module 120, can be used to subsequently limit the number of times the preset programmer has been powered off. Of course, this is not limited to preset programmers; the preset device 310 may also include other consumable components with limits on at least one of the number of power-on times or the number of power-off times, which are not limited here.

[0062] In some embodiments, the output of the control module 130 of the number monitoring module 100 can also be connected to the input of the AC / DC conversion module 140. When the number of power-off times of the preset device 310, as determined by the control module 130 based on the counting module 120, reaches a preset power-off threshold, the output of the control module 130 outputs a third control electrical signal. Accordingly, the AC / DC conversion module 140 can determine that the AC power source is not powered based on the third control electrical signal and maintain the preset device 310 in the power-off state, thereby limiting the number of power-off times of the preset device 310. This is of course not limiting and is not intended to be limiting herein.

[0063] For example, the likelihood of damage to a preset component 310, such as a photometer or test probe, increases with the number of times the preset component 310 is removed. During testing of the photometer or test probe provided on the near-eye display device 300 by the testing device 200, if the testing device 200 removes the photometer or test probe too many times, damage to the preset component 310 may occur. To address this issue, the second detection module 150 can monitor the removal of the preset component 310, such as the photometer or test probe. Accordingly, the counting module 120 can record the number of times the preset component 310, such as the photometer or test probe, is removed, in response to the monitoring information (e.g., the third level signal) from the second monitoring module regarding the removal of the preset component 310. Accordingly, the number of times the preset component 310, such as the photometer or test probe, is removed, recorded by the counting module 120, can be used to limit the number of times the preset component 310, such as the photometer or test probe, is removed. Of course, it is not limited to the photometer and the test probe. The preset device 310 may also include other consumable parts with a limit on the number of disassembly times, which is not limited here.

[0064] In some embodiments, the output of the control module 130 of the count monitoring module 100 can also be connected to the input of the second detection module 150. When the number of times the preset device 310 has been disassembled, as determined by the control module 130 based on the counting module 120, reaches a preset disassembly threshold, the output of the control module 130 outputs a fourth control electrical signal. Accordingly, the second detection module 150 can maintain the preset device 310 in a disassembled state based on the fourth control electrical signal, thereby limiting the number of times the preset device 310 can be disassembled. This is of course not limiting and is not intended to be limiting herein.

[0065] The number monitoring module 100 provided in the embodiment of the present application includes: a first detection module 110, the input end of the first detection module 110 is connected to the test device 200, and the output end of the first detection module 110 is connected to the preset device 310 of the near-eye display device 300; the input end of the first detection module 110 is used to switch the connection state with the output end of the first detection module 110 to a closed state or a disconnected state according to the first control electrical signal output by the test device 200, and the output end of the first detection module 110 is used to output a first level signal as a high level signal when the connection state is a closed state, or output the first level signal as a low level signal when the connection state is a disconnected state; a counting module 120, the counting module 120 is connected to the output end of the first detection module 110; the counting module 120 is used to record the number of times the preset device 310 is used plus one when the first level signal switches from a low level signal to a high level signal, so as to improve the convenience and monitoring effect of the number of times the preset device 310 is used.

[0066] See also Figure 6 , Figure 6 A schematic block diagram of a test system 10 provided in an embodiment of the present application.

[0067] like Figure 6 As shown, the test system 10 includes a test device 200 and the aforementioned number monitoring module 100; the test device 200 is connected to the input end of the first detection module 110 in the number monitoring module 100; the test device 200 is used to test the near-eye display device 300.

[0068] The number monitoring module 100 can assist in monitoring the number of times the testing device 200 tests the near-eye display device 300. For example, the number monitoring module 100 can record at least one of the number of times the testing device 200 uses, powers on, powers off, and disassembles the preset component 310 of the near-eye display device 300, so as to subsequently limit at least one of the number of times the testing device 200 uses, powers on, powers off, and disassembles the preset component 310 of the near-eye display device 300.
