Next, in operation S220, the light emitted from the screen 162 of the electronic device 160 is reflected by the reflector 122 of the detection device 120 to the sensor 164 of the electronic device 160. Specifically, as shown in FIG. 3, when the processor of the electronic device 160 performs one or more detection programs, the electronic device 160 displays a corresponding detection screen through the screen 162. The light L1a of the detection screen is output to the reflector 122 of the detection device 120. The reflecting mirror 122 of the detection device 120 The line L1a is reflected as the light L1b to the sensor 164 of the electronic device 160. For example, the detection screen may be a text file displaying the number of bits of the pi. For another example, the detection picture may be a streaming media playing a network video platform.

Next, in operation S230, the sensor 164 of the electronic device 160 detects the light reflected by the mirror 122 to generate a detected brightness value. In some embodiments, the sensor 164 may be implemented by any sensing element capable of detecting the brightness of light, such as an active pixel sensor. Specifically, when the electronic device 160 performs one or more detection programs, the sensor 164 detects the brightness of the light L1b as a detection brightness value at a predetermined frequency.

Next, in operation S240, the communication element of the electronic device 160 transmits the detected brightness value S1 to the monitoring device 140. Specifically, as shown in FIG. 3, the processor of the electronic device 160 controls the communication element to transmit the detected brightness value S1 to the monitoring device 140. For example, in some embodiments, the processor of the electronic device 160 may wirelessly transmit the detected brightness value S1 to the monitoring device 140 via Bluetooth.

Finally, in operation S250, the monitoring device 140 receives the detected brightness value S1 from the electronic device 160, and determines whether the detected brightness value S1 meets the corresponding predetermined brightness value. Specifically, please refer to Figure 4. FIG. 4 is a detailed flowchart of operation S250 in the detection method 200 according to other embodiments of the present disclosure. As shown in FIG. 4, operation S250 includes operations S251, S252, S253, S254, and S255.

In operation S251, when the monitoring device 140 does not receive the detected brightness value, the monitoring device 140 determines that an abnormality has occurred in the electronic device 160, and proceeds concurrently. Line operation S255. In operation S255, the monitoring device 140 sends a corresponding notification signal A1.

Specifically, as shown in FIG. 5, when the electronic device 160 is abnormal (for example, crashed), the processor of the electronic device 160 does not control the communication element to transmit the detected brightness value, so that the monitoring device 140 fails to receive the detected brightness. value. Accordingly, the monitoring device 140 determines that the electronic device 160 is abnormal by not receiving the detected brightness value, and sends a notification signal A1. In some embodiments, the monitoring device 140 may include a warning horn and / or a warning light. The notification signal A1 may include an email or a message to the inspector, a warning tone or a flashing light, and the like.

With continued reference to FIG. 4, when the monitoring device 140 receives the detected brightness value, operation S252 is performed. In operation S252, when the detected brightness value received by the monitoring device 140 does not meet the corresponding predetermined brightness value, operation S255 is performed, and the monitoring device 140 sends a corresponding notification signal A2.

Specifically, as shown in FIG. 6, when the electronic device 160 does not perform the detection program as expected and the normal detection screen is not displayed (for example, a black screen is displayed), the light L2a emitted from the screen 162 of the electronic device 160 will be normal. The light L1a in the case is different, and the light L2b reflected by the mirror 122 of the detection device 120 will also be different from the reflected light L1b in the normal case. Therefore, the detected brightness value S2 transmitted by the processor of the electronic device 160 through the communication element will not correspond to the corresponding predetermined brightness value, thereby causing the monitoring device 140 to send a corresponding notification signal A2.

In some embodiments, the notification signal A2 includes an email or a message given to the inspector, a warning tone or a warning light, and the like. In other ministries In the sub-embodiment, the notification signal A2 is different from the notification signal A1. For example, the notification signal A1 may be a warning sound, and the notification signal A2 may be two warning sounds. For another example, the email messages of the notification signals A1 and A2 may contain different contents, such as no signal and abnormal value.

With continued reference to FIG. 4, when the detected brightness value received by the monitoring device 140 conforms to the corresponding predetermined brightness value, operation S253 is performed. In operation S253, the electronic device 160 outputs a time stamp generated by the sensor 164 to detect the brightness value to the monitoring device 140. It is determined by the monitoring device 140 whether the time stamp and the detected brightness value conform to the corresponding predetermined time stamp and the predetermined brightness value. When the monitoring device 140 determines that the time stamp and the detected brightness value do not conform to the corresponding predetermined time stamp and the predetermined brightness value, operation S255 is performed, and the monitoring device 140 issues a corresponding notification. When the monitoring device 140 determines that the time stamp and the detected brightness value correspond to the corresponding predetermined time stamp and the predetermined brightness value, operation S254 is performed to continue the detection.

Specifically, when the sensor 164 of the electronic device 160 detects the light reflected by the reflector 122 to generate the detected brightness value, the processor of the electronic device 160 records the time when the detected brightness value is generated as the time through the sensor 164. mark. In addition, the processor of the electronic device 160 transmits the detected brightness value and the corresponding time stamp to the monitoring device 140 through the communication element.

It is worth noting that although the above methods are shown and described as a series of operations or events, it should be understood that the order of these operations or events shown should not be construed as limiting. For example, operations S252, S253 may occur in a different order and / or concurrently with steps or events other than the steps or events shown and / or described herein. For another example At the same time as the notification in S255, the detection can also continue. In addition, when implementing one or more aspects or embodiments described herein, not all steps shown here are necessary. In addition, one or more steps herein may also be performed in one or more separate steps and / or stages.

Please refer to Figure 7. FIG. 7 is a distribution diagram of monitoring data according to some embodiments of the present disclosure. As shown in FIG. 7, the monitoring device 140 establishes a distribution map for the detected brightness values and corresponding time stamps according to different detection programs, and obtains a decision boundary of each detection program according to machine learning. Specifically, first, different electronic devices 160 to be tested are used to perform the same detection program and obtain the detection brightness value, and then the monitoring device 140 receives the detection brightness value and the corresponding time stamp to establish monitoring data (as shown in P0 in the figure). ), And use the formula of average, median, or arithmetic mean to calculate the decision boundary based on the received detected brightness value.

According to this, after the monitoring device 140 obtains the decision boundary of each detection program, it can instantly compare whether the monitoring data returned by each electronic device 160 conforms to the brightness value and time stamp that the current detection program presets.

For example, one or more samples of electronic devices or other electronic devices to be tested are selected as templates before the testing is officially performed. The template is placed in the detection device 120 for detection to obtain a detection brightness value and a time stamp. The monitoring device 140 establishes a monitoring data distribution map based on the obtained detection brightness value and time stamp according to different detection programs, and uses supervised learning to establish a training data set for each detection program. (training set) to get the decision boundary of each detection program. The monitoring device 140 establishes a predetermined brightness value and a predetermined time stamp according to the decision boundary. Then, during the formal detection, the monitoring device 140 compares the monitoring data with the preset detection program sequence, the predetermined brightness value, and the predetermined time stamp to the monitoring data, so as to determine whether the detected electronic device 160 is abnormal.

Please refer to FIG. 8, which is a distribution diagram of monitoring data according to other embodiments of the present disclosure. As shown in FIG. 8, the monitoring data P1 falls within the decision boundary, so it is judged to conform to the time stamp and the predetermined brightness value, and the monitoring data P2 located outside the decision boundary is judged to fail to meet the time stamp and the predetermined brightness value. In some embodiments, the width of the decision boundary is approximately the length of time during which the detection program is performed, and the height of the decision boundary is approximately the average positive and negative brightness standard deviation of the screen brightness performed by the detection program.

In other words, for example, when the detection program has started but the brightness value is still close to zero, such as the monitoring data D1 in FIG. 8, it can be presumed that the screen 162 of the electronic device 160 is still in a black screen state, and it will be judged as non-compliant. Time stamp and predetermined brightness value. As another example, when the brightness value is extremely high during the detection program, such as the monitoring data D2 in FIG. 8, it can be inferred that the screen 162 of the electronic device 160 has a white screen state, and it will be judged that it does not meet the time mark and schedule. Brightness value. In addition, when the brightness value is normal but the time exceeds the normal operation range of the detection program, such as the monitoring data D3 in FIG. 8, it can be presumed that the electronic device 160 operates too slowly and will be judged as not meeting the time stamp and the predetermined brightness value. In this way, according to the received detected brightness value and the time stamp, the monitoring device 140 can determine whether the monitoring data is abnormal according to the decision boundary, and can immediately know the abnormal state of the electronic device according to the distribution of the monitoring data.

In summary, compared to traditional product testing, which is only distinguished as passing and failing, and problems cannot be detected immediately, the detection system 100 and detection method 200 of this case can transmit real-time monitoring data, which can Send notifications in the shortest time. The monitoring device 140 can distinguish whether the detection program is completed within a reasonable time, and when it is not completed, it can identify which detection program has an abnormality, thereby reducing the time for analyzing the problem. In addition, the detection device 120 includes only the reflecting mirror 122, which is not only low in cost, but also uses a physical device to reflect light, which can avoid misjudgment caused by failure of electronic components included in the detection device.

Although the present invention has been disclosed as above by way of example, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and retouches without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be determined by the scope of the attached patent application.
