Description

Operation state detection system and method thereof

The present invention relates to a detection system and a detection method for detecting an electronic device, and more particularly, to a detection system and a detection method for detecting the operation state of the electronic device.

Most of the current inspection systems use one or more monitors to monitor the operation status of one or more electronic devices to be tested during the test. The detection system will receive the screen or image displayed by the electronic device to be tested through the monitor. However, the monitor may be affected by ambient light from the outside (eg, reflection or glare), which may cause misjudgment by the detection system, thereby reducing the detection accuracy. Therefore, each electronic device to be tested and the corresponding monitor need to be shielded from external ambient light by a shading screen or a shading box. Therefore, inspection systems often waste a lot of space due to blackout curtains or blackout boxes. In addition, the shading screen or shading box will also affect the heat dissipation of the operation of the electronic device under test.

Therefore, how to improve the detection accuracy of the detection system and reduce the usable space of the detection system is one of the topics that those skilled in the art are working hard to study.

The present invention provides an operation state detection system and an operation state detection system method, which can improve the detection accuracy of the detection system and reduce the usage space of the detection system.

The operating state detection system includes at least one light sensor and at least one processor. Each of the at least one light sensor has a lens. The lenses of the at least one light sensor are respectively attached to at least one screen of the at least one electronic device in a one-to-one manner. Each of the at least one light sensor is respectively configured to receive a partial image of an image displayed by a corresponding one of the at least one screen. The at least one processor is respectively coupled to the at least one light sensor in a one-to-one manner. The at least one processor is each configured to receive a partial image, when the partial image is stationary, time the stationary time length of the stationary partial image, and when the stationary time length is determined to be greater than a preset time length, determine The corresponding electronic device is in a shutdown state.

The operation state detection method of the present invention is used to detect the operation state of at least one electronic device. The operation state detection method includes: attaching the lens of at least one light sensor to at least one screen of the at least one electronic device in a one-to-one manner; receiving the at least one light sensor respectively by the at least one light sensor at least one partial image in at least one image displayed on at least one screen; when at least one of the at least one partial image is still, timing the still time length of the at least one partial image that is still; and when When the stationary time length is judged to be greater than the preset time length, it is judged that Make sure that the corresponding electronic device is in a shutdown state.

Based on the above, in the operating state detection system, the lens of the light sensor is closely attached to the screen. Therefore, the light sensor does not receive reflections or glare caused by external ambient light. The operational status detection system may not require a blackout curtain or a blackout box. As a result, compared with the current detection system, the operation state detection system has higher detection accuracy and lower usage space. In addition, the processor determines the operation state of the corresponding electronic device in a divisional manner. Therefore, the processing performance requirement of the processor of the operating state detection system can be lower.

Rather, these embodiments are merely exemplary of apparatus and methods within the scope of the present invention.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an operation state detection system according to a first embodiment of the present invention. In this embodiment, the operating state detection system 100 can detect the operating states of the electronic devices D1 and D2. For example, the operation state detection system 100 can detect whether the operation of the electronic devices D1 and D2 is normal. The above-mentioned testing can be carried out in the research and development stage, the pre-production test or the quality assurance stage. In this embodiment, the electronic devices D1 and D2 are exemplified by notebook computers. The electronic devices D1 and D2 of the present invention may be electronic devices having a screen (such as a notebook computer, a mobile phone, a tablet computer or a desktop computer, etc.), which is not limited to this embodiment.

In this embodiment, the operating state detection system 100 includes a light sensor 110_1, 110_2 and processors 120_1, 120_2. The light sensor 110_1 has a lens 112_1. The light sensor 110_2 has a lens 112_2. The lenses 112_1 and 112_2 of the light sensors 110_1 and 110_2 are closely attached to the screens SC1 and SC2 of the electronic devices D1 and D2 in a one-to-one manner. In this embodiment, the light sensor 110_1 receives the partial image P1 in the image displayed on the screen SC1. Because the lens 112_1 is closely attached to the screen SC1. Therefore, the range of the partial image P1 is substantially equal to the image receiving range of the lens 112_1. Similarly, the light sensor 110_2 receives the partial image P2 in the image displayed on the screen SC2. The range of the partial image P2 is substantially equal to the image receiving range of the lens 112_2. The light sensors 110_1 and 110_2 of this embodiment may be implemented by an image capturing device or a color sensing device without a light source.

In this embodiment, the processors 120_1 and 120_2 are respectively coupled to the light sensors 110_1 and 110_2 in a one-to-one manner. In this embodiment, the processor 120_1 is coupled to the light sensor 110_1 to receive the partial image P1. The processor 120_2 is coupled to the light sensor 110_2 to receive the partial image P2. The processors 120_1 and 120_2 respectively determine the operation states of the electronic devices D1 and D2 according to the partial images P1 and P2 . Taking the processor 120_1 as an example, when the partial image P1 is determined to be still, the processor 120_1 will count the still time length of the still partial image. The processor 120_1 further determines whether the stationary time length is greater than the preset time length DT. When the stationary time length is determined to be greater than the preset time length DT, the processor 120_1 determines that the corresponding electronic device D1 is in a shutdown state. The preset time length DT in this embodiment is built in the processors 120_1 and 120_2. The preset time length DT can be adjusted based on actual detection requirements. The preset time length DT may be several seconds or several minutes. based on real Depending on the actual detection requirement, the preset time length DT of the processor 120_1 and the preset time length DT of the processor 120_2 may be the same or different.

In this embodiment, the processors 120_1 and 120_2 may be, for example, a central processing unit (Central Processing Unit, CPU), or other programmable general-purpose or special-purpose microprocessors (Microprocessors), digital signal processing Digital Signal Processor (DSP), Programmable Controller, Application Specific Integrated Circuits (ASIC), Programmable Logic Device (PLD) or other similar devices or combinations of these devices . The processors 120_1 and 120_2 in this embodiment may be implemented by single-chip devices (Arduino series, Raspberry Pi).

In this embodiment, the operating state detection system 100 further includes a host 130 . The host 130 is coupled to the processors 120_1 and 120_2. The processors 120_1 and 120_2 respectively provide the determination results related to the operating states of the electronic devices D1 and D2 to the host 130 . For example, taking the processor 120_1 as an example, when the processor 120_1 determines that the electronic device D1 is in the off state, the processor 120_1 provides the determination result that the electronic device D1 is in the off state to the host 130 . The host 130 in this embodiment may be any form of central control terminal, server or cloud server. However, this case is not limited to this. During actual execution, the processor 120_1 can also independently process the determination result.

In this embodiment, the number of the electronic devices D1 and D2 , the number of the light sensors 110_1 and 110_2 and the number of the processors 120_1 and 120_2 are respectively two as an example. However, the present invention is not limited to the number of electronic devices, the number of light sensors and the number of processors. The number of electronic devices and the number of light sensors in the present invention are based on And the number of processors can be one or more.

It is worth mentioning here that the lenses 112_1 and 112_2 are attached to the screens SC1 and SC2 respectively. Therefore, the light sensors 110_1 and 110_2 will not receive reflection or glare caused by external ambient light. The operating state detection system 100 may not require a blackout curtain or a blackout box. In this way, compared with the current detection system, the operation state detection system 100 of the present embodiment has higher detection accuracy and lower usage space. Besides, the processors 120_1 and 120_2 respectively judge the operation states of the corresponding electronic devices D1 and D2 in a division manner. Therefore, the processing performance requirements of the processors 120_1 and 120_2 of the operating state detection system 100 can be lower.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a schematic diagram of a method for detecting an operation state according to a first embodiment of the present invention. The operation state detection method S100 of this embodiment is applicable to the operation state detection system 100 . In step S110, the lenses 112_1 and 112_2 of the light sensors 110_1 and 110_2 are respectively attached to the screens SC1 and SC2 of the electronic devices D1 and D2 in a one-to-one manner. For example, the lens 112_1 of the light sensor 110_1 is closely attached to the screen SC1 of the electronic device D1. The lens 112_2 of the light sensor 110_2 is closely attached to the screen SC2 of the electronic device D2. In step S120, the operation state detection system 100 receives the partial image P1 in the displayed image of the screen SC1 through the photo sensor 110_1, and receives the partial image P1 in the displayed image of the screen SC2 through the optical sensor 110_2 Image P2.

In step S130, it is determined whether the partial images P1 and P2 are still. Step S130 may be performed by the processors 120_1 and 120_2 in a divisional manner. When the partial images P1 and P2 are not stationary, the operation state detection method S100 It will return to step S120. That is to say, when the partial images P1 and P2 continue to change, the operation state detection system 100 will continuously execute step S120. On the other hand, when at least one of the partial images P1 and P2 is stationary, the operation state detection method S100 will proceed to step S140 to count the stationary time length of the stationary partial images. In step S150, it is determined whether the stationary time length is greater than the preset time length DT. When the still time length is determined to be greater than the preset time length DT, the operation state detection method S100 determines in step S160 that the electronic device corresponding to the static partial image is in a shutdown state. On the other hand, when the stationary time length is determined to be less than or equal to the preset time length DT, the operation state detection method S100 returns to step S120.

For example, when the processor 120_1 determines in step S130 that the partial image P1 is still, the processor 120_1 will time the still time length of the partial image P1 in step S140. The processor 120_1 further determines in step S150 whether the still time length of the partial image P1 is greater than the preset time length DT. If the processor 120_1 determines that the still time length is greater than the preset time length DT, it means that the partial image P1 has not changed, and the unchangeable time length of the partial image P1 exceeds the preset time length DT. Therefore, the processor 120_1 determines in step S160 that the electronic device D1 is in a shutdown state.

For another example, if the processor 120_1 determines in step S130 that the partial image P1 continues to change, or determines in step S150 that the stationary time length of the partial image P1 is less than or equal to the preset time length DT, the processor 120_1 will The partial video P1 is continuously received in step S120.

Please refer to FIG. 1 and FIG. 3 at the same time. FIG. 3 is a schematic diagram of another operating state detection method according to the first embodiment of the present invention. In this embodiment, the operation state detection method S200 is applicable to the operation state detection system 100 . Compared with the operation state detection method S100 in FIG. 2 , the operation state detection method S400 of this embodiment further includes step S170 . The operation state detection method S200 further determines the color system of the color of the still partial image in step S170. The color system of the color of the still partial image is related to the cause of the crash state. For example, the color system of the color of the still partial image may be a gray color system (such as a black picture and the backlight module is enabled, or a white picture), a black color system (such as a black picture and the backlight module is disabled), ) and one of the blue color schemes (such as blue screen). The processors 120_1 and 120_2 of the operating state detection system 100 can sort out the approximate cause of the crash according to the color system of the color of the still partial image.

For example, step S170 of this embodiment is after step S150. That is, when the still time length is determined to be greater than the preset time length DT in step S150 , the operation state detection method S200 further determines the color system of the color of the partial image where the stillness occurs in step S170 . However, the present invention is not limited to this. According to actual detection requirements, step S170 of the present invention may be between steps S130-S160, or after step S160.

Please refer to FIG. 1 and FIG. 4 at the same time. FIG. 4 is a schematic diagram of a method for detecting yet another operating state according to the first embodiment of the present invention. In this embodiment, the operation state detection method S300 is applicable to the operation state detection system 100 . Compared with the operation state detection method S100 of FIG. 2 , the operation state detection method S300 of the present embodiment It also includes step S180. In the operation state detection method S300, in step S180, it is determined whether the color of the static partial image is maintained in one of a plurality of specific color systems. The above-mentioned specific color systems at least include gray color system (such as black screen and the backlight module is enabled, or white screen), black color system (such as black screen and the backlight module is disabled), and blue color system (such as blue screen).

For example, step S180 in this embodiment is after step S150. When the still time length is determined to be greater than the preset time length DT in step S150 , the operation state detection method S300 further determines in step S180 whether the color of the partial image in which the stillness occurs is maintained among the above-mentioned specific color systems one. When the color of the static partial image is one of the above-mentioned specific color systems, the operation state detection method S300 will proceed to step S160 to determine that the corresponding electronic device is in a shutdown state. On the other hand, when the color of the still partial image is not one of the above-mentioned specific color systems, the operation state detection method S300 returns to step S120. That is to say, in this embodiment, when it is determined that the stationary time length is greater than the preset time length DT and the color of the partial image in which the stationary image occurs is maintained in one of the above-mentioned specific color systems, the corresponding electronic device is determined to be to be in a shutdown state.

According to actual detection requirements, step S180 of the present invention may be between steps S130-S160. The present invention is not limited to the order of step S180 in the operation state detection method S300 in this embodiment.

The accommodating groove 510 covers a part of the photo sensor, and only the lens 112 of the photo sensor is exposed to the outside of the accommodating groove 510 . In this embodiment, the fixing part 520 fixes the positioning structure FS on the screen, so that the lens 112 is closely attached to the display surface of the screen. In this embodiment, a portion of the fixing portion 520 may be designed as a hook. However, the present invention is not limited to this. In some embodiments, a portion of the fixing portion 520 may be designed as a support frame.

Please refer to FIG. 1 and FIG. 6 at the same time. FIG. 6 is a schematic diagram of a positioning structure mounted on an electronic device according to an embodiment of the present invention.

In this way, the lens 112_1 can directly receive the partial image P1 displayed on the screen SC1 without receiving ambient light from the outside.

Please refer to FIG. 7 and FIG. 8 at the same time. FIG. 7 is a second embodiment of the present invention. The schematic diagram of the operating state detection system shown. FIG. 8 is a schematic diagram of a method for detecting an operating state according to a second embodiment of the present invention. In this embodiment, the operating state detection system 200 includes light sensors 210_1 and 210_2, processors 220_1 and 220_2, a host 230 and cameras 240_1 and 240_2. The coupling relationship between the light sensors 210_1, 210_2, the processors 220_1, 220_2, and the host 230 can be, for example, the same as the coupling relationship between the light sensors 210_1, 210_2, the processors 220_1, 220_2, and the host 230, so will not be repeated here. In this embodiment, the cameras 240_1 and 240_2 are respectively coupled to the processors 220_1 and 220_2 in a one-to-one manner, and record images displayed on the corresponding screens SC1 and SC2 in a one-to-one manner, respectively. For example, the camera 240_1 is coupled to the processor 220_1 and records the image displayed on the screen SC1. The camera 240_2 is coupled to the processor 220_2 and records the image displayed on the screen SC2.

In this embodiment, the operation state detection method S400 is applicable to the operation state detection system 200 . In step S410, the lenses 212_1 and 212_2 of the light sensors 210_1 and 210_2 are respectively attached to the screens SC1 and SC2 of the electronic devices D1 and D2 in a one-to-one manner. For example, the lens 212_1 is closely attached to the screen SC1 of the electronic device D1. The lens 212_2 is closely attached to the screen SC2 of the electronic device D2. In step S420, the operating state detection system 200 receives the partial image P1 in the displayed image of the screen SC1 through the photo sensor 210_1, and receives the partial image P1 in the displayed image of the screen SC2 through the optical sensor 210_2 Image P2. In addition, the operating state detection system 200 also uses the camera 240_1 to record the image displayed on the screen SC1, and uses the camera 240_2 to record the image displayed on the screen SC2. In this embodiment, the camera 240_1 can record the image displayed on the screen SC1 based on the instruction or command of the processor 220_1. The camera 240_2 can record the image displayed on the screen SC2 based on the instruction or command of the processor 220_2.

In step S430, it is determined whether the partial images P1 and P2 are still. When neither of the partial images P1 and P2 is stationary, the operation state detection method S400 returns to step S420. On the other hand, when at least one of the partial images P1 and P2 is stationary, the operation state detection method S400 will proceed to step S440 to count the stationary time length of the stationary partial images. In step S450, it is determined whether the stationary time length is greater than the preset time length DT. When the still time length is determined to be greater than the preset time length DT, the operation state detection method S400 determines in step S460 that the electronic device corresponding to the static partial image is in a shutdown state. On the other hand, when the stationary time length is determined to be less than or equal to the preset time length DT, the operation state detection method S400 returns to step S420. The implementation details of steps S430 - S460 of the operation state detection method S400 can be sufficiently taught from the examples of steps S130 - S160 of the operation state detection method S100 - S300 , so the description will not be repeated here.

In step S470 , the operation state detection system 200 completes the video recording to obtain the abnormal occurrence video ABV of the electronic device in the off state, and captures the abnormal picture ABP of the electronic device in the off state. In step S480 , the operation state detection system 200 provides abnormal video ABV and abnormal picture ABP to the host 230 . For example, taking the electronic device D1 as an example, when the electronic device D1 is determined to be in a shutdown state in step S460, the processor 220_1 in step S470 The camera 240_1 will be instructed to complete the video recording, so as to obtain the abnormal occurrence video ABV of the electronic device D1. In addition, the processor 220_1 further instructs the camera 240_1 to capture the abnormal picture ABP when the electronic device D1 is in a shutdown state. In step S470, the processor 220_1 may instruct the camera 240_1 to capture the image displayed on the screen SC1 of the electronic device D1 at the highest resolution to obtain the abnormal picture ABP. In step S480 , the processor 220_1 provides the abnormal picture ABP and the abnormal occurrence video ABV of the electronic device D1 to the host 230 .

For example, the host 230 receives the abnormal occurrence video ABV and the abnormal picture ABP through the processor 220_1. The abnormal occurrence video ABV records the image of the electronic device D1 when it crashes and the display process before the crash occurs. Therefore, the host 230 can obtain the display process when the electronic device D1 crashes according to the abnormal occurrence video ABV. The engineer can learn the possible process of the crash of the electronic device D1 through the abnormal occurrence video ABV.

For another example, the abnormal picture ABP may display the content of the image when the electronic device D1 crashes. The content of the image when the electronic device D1 crashes is, for example, one of a black image, a white image, a hang still image, and a blue image. The host 230 can obtain the error code (eg, "Stop code: CRITICAL_PROCESS_DIED" in the blue screen) or text displayed when the electronic device D1 crashes according to the abnormal picture ABP. The engineer can know the reason for the crash of the electronic device D1 through the content of the error code or text.

To sum up, in the operating state detection system of the present invention, the lens of the light sensor is closely attached to the screen. The light sensor does not receive external ambient light resulting in reflections or glare. Therefore, the operating state detection system of the present invention may not need a light-shielding curtain or a light-shielding box. In this way, the operation state detection system and the operation state detection method of the present invention can enable the operation state detection structure of the electronic device to have higher detection accuracy and lower usage space. In addition, the processor of the present invention judges the operation state of the corresponding electronic device in a divisional manner. Therefore, the processing performance requirement of the processor of the operating state detection system of the present invention can be lower.
