The electronic device 200 may be a device with a display screen such as a smart energy storage device, an outdoor mobile air conditioner, a lawn mower, a household appliance, and other smart devices.
Fig. 1 is merely an exemplary illustration of the fault detection device 100 and the electronic device 200, and is not meant to be limiting, and in other embodiments, the fault detection device 100 and the electronic device 200 may include more or less components than illustrated, or may combine certain components, or may replace different components, and the fault detection device 100 and the electronic device 200 may further include input and output devices, network access devices, and the like.
Fig. 2 is a flowchart of a fault detection method according to an embodiment of the present application, as shown in fig. 2, where the fault detection method according to the embodiment of the present application is applied to a fault detection device (such as the fault detection device 100 of fig. 1) for performing fault detection on an electronic device (such as the electronic device 200 of fig. 1). The order of the steps in the flowchart may be changed and some steps may be omitted according to various needs. As shown in fig. 2, the method comprises the following steps:
step S201, acquiring operation parameters of the electronic device in the operation process.
In some embodiments of the present application, an electronic device (e.g., an energy storage device) may generate an operation parameter during an actual operation process, where the operation parameter may be used to represent an operation state of the electronic device, for example, by obtaining a remaining power in the operation parameter of the electronic device to obtain a battery capacity state of the electronic device, and for example, detecting that a user clicks a control on a display screen to trigger a change of the operation state, the operation parameter after the operation state is changed may be obtained, and obtaining the operation state of the electronic device at this time by obtaining the changed operation parameter, for example, the operation parameter includes a display frequency, the user clicks a control for switching the display frequency, records the display frequency after the switching at this time, and stores the display frequency before the switching and the display frequency after the switching in the electronic device, and obtains the display frequency state of the display screen at this time according to the display frequency after the switching.
The operating parameters of the electronic device may be transmitted to other devices (e.g., fault detection devices) via the input/output interface for analysis and processing by the other devices based on the acquired operating parameters. The operating parameters may include display interface information, signaling information, remaining power, output voltage, output current, etc. of the electronic device. The operating parameters of the electronic device may also be displayed via a display of the electronic device, which is not limited by the present application.
In the embodiment of the application, the fault detection device can be used for acquiring the operation parameters of the electronic device in the operation process so as to detect the data transmission performance of the electronic device or other performances of the electronic device.
Step S202, a display image of a display screen of the electronic equipment in the running process is obtained.
In some embodiments of the present application, the electronic device may include one or more display screens, which may be used to display operation parameters of the electronic device, or display a related chart, icon, or graphic that can represent the operation parameters, where the operation condition of the electronic device may be intuitively obtained through the display screens, for example, the electronic device is used as an energy storage device to describe, and when the remaining capacity of the energy storage device is 20%, 20% of the remaining capacity is displayed in an area corresponding to the remaining capacity of the display screen or the remaining capacity is displayed in the form of an icon, so as to remind a user to timely charge the energy storage device.
In some embodiments of the present application, the display image of the display screen may intuitively reflect the state of the display screen during the operation of the electronic device, for example, when the display screen flashes, the displayed display image may continuously flash, and the display image may intuitively reflect the operation parameter. Accordingly, it is possible to determine whether or not the electronic device has a display failure or a communication failure by acquiring the display image. For another example, a preset icon associated with the preset state may be displayed on the display screen, for indicating the current state of the electronic device, for example, indicating that the electronic device needs to be charged as soon as possible due to insufficient power.
In the embodiment of the application, the fault detection equipment can be adopted to acquire the display image of the display screen of the electronic equipment in the running process, and the display screen can be shot by the shooting device of the fault detection equipment so as to detect the data transmission performance or the display performance of the electronic equipment.
Step S203, a reference image of the display screen is acquired according to the operation parameters.
In some embodiments of the present application, the reference image may be a standard display image of the display screen corresponding to different working conditions, that is, may be a theoretical display image of the electronic device corresponding to different operation parameters, and may be directly obtained from the memory, where the reference image in the memory may be automatically generated or obtained from a result of a previous test, which is not limited by the present application.
In some embodiments of the present application, after obtaining the operation parameters of the electronic device, a corresponding reference image may be found according to the operation parameters, for example, the operation parameters are 20% of the remaining power, and then, based on the 20% of the remaining power, the reference image with 20% of the remaining power in the memory is obtained. For another example, by clicking a control on the display screen, the touch signal is transmitted, so as to obtain the operation parameters of the electronic device at the moment, and thus, the corresponding reference image is obtained.
The above is merely an example, and the present application is not limited thereto, and the corresponding reference image may be obtained according to other operation parameters.
Step S204, outputting a fault prompting signal when the display image is not matched with the reference image.
In some embodiments of the present application, when capturing a display image and acquiring corresponding operation parameters, capturing time information may be acquired, for example, when capturing the display image 1 at a first time (for example, 9 am), simultaneously acquiring the operation parameters a corresponding to the first time, where the display image 1 and the time information carried by the operation parameters a are both the first time.
In some embodiments of the present application, whether the electronic device has a fault or not may be determined by comparing the display image and the reference image, which have the same time information, so as to achieve the purpose of testing the electronic device. And acquiring time information corresponding to the display image, acquiring a corresponding reference image according to the operation parameters, and acquiring the time information corresponding to the reference image after the reference image is acquired.
For example, in some examples, fig. 3 is a schematic diagram of matching a display image with a reference image according to an embodiment of the present application, and as shown in fig. 3, the display image 1 is acquired at a first time T1 and an operation parameter a corresponding to the first time T1 is acquired, and the display image 2 is acquired at a second time T2 and an operation parameter B corresponding to the second time T2 is acquired. And then searching the reference image 3 corresponding to the operation parameter A based on the operation parameter A, and searching the reference image 4 corresponding to the operation parameter B based on the operation parameter B. Further, the third time T3 carried by the reference image 3 and the fourth time T4 carried by the reference image 4 are acquired. If the first time T1 is the same as the third time T3, the connection line (1) shown in fig. 3 represents the comparison display image 1 and the reference image 3, and if the second time T2 is the same as the fourth time T4, the connection line (2) shown in fig. 3 represents the comparison display image 2 and the reference image 4.
In other examples, if the first time T1 is equal to the fourth time T4, the connection line (3) shown in fig. 3 represents the comparison display image 1 and the reference image 4. At this time, the display image 1 corresponds to the operation parameter a, and the reference image 4 corresponds to the operation parameter B, since the display image is one way of reflecting the operation parameter. Therefore, the display image 1 does not match the reference image 4, i.e., a malfunction notification signal is output.
Similarly, if the second time T2 is equal to the third time T3, the connection line (4) shown in fig. 3 indicates that the display image 2 and the reference image 3 are aligned, and at this time, the display image 2 and the reference image 3 do not match.
In some embodiments of the application, it may be determined whether there is a malfunction in the data transmission performance of the electronic device by comparing whether the display image is consistent with the reference image.
For example, in some examples, after determining that the display image does not match the reference image, if an operating parameter of the electronic device detected through a transmission interface connected to the display screen does not match display information characterized in the display image of the display screen at this time, it is determined that a data transmission failure occurs between the display screen and a data transmission module within the electronic device. For example, if one of the operation parameters of the electronic device, for example, the remaining power is 19% at the first time, and the display image in the display screen of the electronic device captured by the capturing device is characterized in that the current remaining power of the electronic device is 20%, and if the remaining power corresponding to the first time is 19% through the transmission interface connected with the display screen, it is determined that a data transmission fault occurs between the display screen and the data transmission module in the electronic device, so that the operation parameter received by the display screen is not matched with the actual operation parameter, and further the display image displayed on the display screen is not matched with the reference image. For the test equipment to perform data transmission performance error marking on the faults and output fault prompting signals so as to further eliminate the faults.
In the embodiment of the application, the display fault type of the screen can be a fault on hardware such as a bright spot or a splash screen of the screen, or an error in communication between the screen and a control unit in the electronic device, for example, decoding failure after the screen receives data or delay of communication. In order to perform fault test on the electronic equipment under various working conditions, the application can acquire the operation parameters of the electronic equipment in the operation process and acquire the display images of the display screen of the electronic equipment as the data basis of the fault test of the electronic equipment; secondly, after the display image is obtained, in order to judge whether the display screen has faults or not through the display image, the image actually displayed by the electronic equipment can be obtained through the operation parameters to serve as a reference image, and finally, when the fact that the display image is not matched with the reference image is determined, a fault prompting signal can be output. The operation parameters of the electronic equipment in the operation process represent various working conditions which can occur in the actual use of the electronic equipment after leaving a factory, including startup, shutdown, networking and the like, so that the display screen is detected according to the operation parameters of the electronic equipment, the situation that if the display screen fails under various working conditions can be met, and a tester can be timely prompted.
Fig. 4 is a flowchart of a fault detection method according to another embodiment of the present application. In order to improve the test efficiency, an embodiment as shown in fig. 4 is provided, comprising the steps of:
step S401, acquiring operation parameters of the electronic device in the operation process.
Step S402, a display image of a display screen of the electronic device in the running process is obtained.
Step S403, obtaining a reference image of the display screen according to the operation parameters.
In some embodiments of the present application, the specific descriptions of steps S401 to S403 may refer to steps S201 to S203 in the embodiment provided in fig. 2, and the descriptions are not repeated here.
Step S404, judging whether any display image is not matched with the reference image.
If any of the display images does not match the reference image, step S405 is executed to output a fault prompting signal, save the display image that does not match the reference image, and clear the other display images.
In some embodiments of the present application, an operation parameter corresponding to an electronic device may be acquired, and a plurality of display images may be acquired through a photographing device, and a reference image corresponding to the operation parameter may be acquired from a plurality of stored reference images, so as to compare the acquired display images and the reference image according to a sequence of the operation parameter. If any display image is not matched with the reference image according to the corresponding parameters of the electronic equipment in the detection process, the abnormal display image is stored, other display images which are not detected yet and the corresponding operation parameters are cleared, and the subsequent display images can not be detected.
For example, in some examples, 30 display images and corresponding 30 reference images acquired according to operation data are sequentially acquired according to a change sequence of operation parameters of the electronic device, the 30 reference images are sequentially compared with the acquired display images of the display screen, if when the 15 th display image is detected, and if there is a mismatch with the corresponding reference image, all display images and corresponding operation parameters after the 16 th display image are discarded, and the first 15 display images and operation parameters are saved. The 30 display images are sequenced according to shooting time, and in the detection process, detection is carried out piece by piece based on shooting time.
In other examples, detection may be performed for different display information and data transmission performance in the display screen, for example, before fault detection of the electronic device, a set of test procedures may be created for the electronic device, where the test procedures include testing each performance of the electronic device, and may include N procedures, for example, procedure 1 includes determining whether a display icon is normal or not: determining whether the display icon of the display screen is normal by judging whether the display image is matched with the reference image, executing a process 2 after determining whether the display icon is normal, judging whether the display number of the residual electric quantity is normal again, judging whether the display image is matched with the reference image again, determining whether the display number of the residual electric quantity of the display screen is normal, if the display number of the residual electric quantity is abnormal, not executing the processes 3-N, storing the display image which is not matched with the reference image, clearing other display images, and marking the display image which is not matched with the reference image, for example, marking the display number which is marked as the residual electric quantity is abnormal.
In the embodiment of the application, when any display image is not matched with the reference image, the detected display image and the corresponding operation parameters can be stored to update the fault detection data in the memory of the fault detection device, so that the detection efficiency of the subsequent electronic device is improved to a certain extent, and meanwhile, the display image which is not detected and the corresponding operation parameters are eliminated, so that the detection flow can be optimized, the detection steps can be reduced, and the memory space occupying the memory of the fault detection device can be reduced.
If any display image is not matched with the reference image, step S406 is executed to confirm that the display function of the display screen of the electronic device is normal.
In some embodiments of the present application, if the acquired multiple display images can be successfully matched with the corresponding reference images, it may be determined that the display function of the display screen of the electronic device is normal, for example, if the acquired 30 display images are successfully matched with the corresponding 30 reference images, it may be determined that the display function of the display screen of the electronic device is normal.
Fig. 5 is a flowchart of a fault detection method according to another embodiment of the present application. In order to improve the sampling efficiency of the display image, an embodiment as shown in fig. 5 is provided, comprising the steps of:
step S501, acquiring an operation parameter of the electronic device in an operation process.
In some embodiments of the present application, the specific description of step S501 may refer to step S201 in the embodiment provided in fig. 2, and the description is not repeated here.
Step S502, determining whether the electronic device is in a stable operation state.
In some embodiments of the present application, the steady operation state refers to a state that a state of a system is no longer changed with time, and the steady operation state of the electronic device may be identified through a preset duration, a parameter operation range, and the like.
If the electronic device is in a stable running state, step S503 is executed to acquire a display image of the display screen of the electronic device in the running process at a preset first sampling frequency.
In some embodiments of the present application, when the electronic device is in a stable running state, since the frequency of changing the display image of the display screen is slower, the display image of the display screen of the electronic device in the running process may be obtained by using the first sampling frequency, and in particular, the display screen may be photographed by using the photographing device at the first sampling frequency, so as to obtain the display image. For example, in some examples, the first sampling frequency is preset to capture one display image every 30ms, and according to a preset number of captures, one display image every 30ms is captured until the number of captures is reached.
If the electronic device is in an unstable operation state, step S504 is executed to obtain a display image of the display screen of the electronic device in the operation process at a preset second sampling frequency.
In some embodiments of the present application, if the electronic device is in an unstable operation state, for example, the electronic device is just started, the electronic device is switching a mode, or the electronic device is connected to a power supply device to charge the electronic device, a second sampling frequency may be used to obtain a display image of the display screen of the electronic device in the operation process, where the first sampling frequency is smaller than the second sampling frequency, and since the electronic device is in an unstable state at this time, the display image has a faster changing frequency, and the second sampling frequency smaller than the first sampling frequency may be used to perform shooting, so as to shorten the shooting time, thereby ensuring that a display image with obvious change of an operation parameter and an operation parameter can be obtained, and enhancing the monitoring of the display screen.
For example, in some examples, the second sampling frequency is preset to take one display image every 15ms, and according to the preset number of shots, one display image every 15ms is taken until the number of shots is reached.
