In this embodiment, the device to be detected is a television, and in other embodiments, the device to be detected may also be a computer, a mobile phone, a tablet, or the like having a display function. The user can finish the operation of inputting the key value by operating the keyboard or other peripheral input equipment matched with the monitoring device and pressing the key or touching the specific control, and the preset operation instruction of the key value input by the user on the monitoring device is an aging mode instruction.
The video information corresponding to the aging mode instruction can be sent to the display equipment to be tested in a wired transmission mode and/or a wireless transmission mode, the communication mode of the monitoring device and the display equipment to be tested is a wired transmission mode, and a worker connects the monitoring device and the display equipment to be tested in advance through a data line. Through the wired transmission mode, the efficiency of data transmission can be improved, communication faults or abnormal phenomena of the monitoring device and the tested display equipment caused by the data transmission are reduced, and the robustness and the reliability of monitoring the tested display equipment in the aging test are improved.
It should be noted that one monitoring apparatus may be in communication connection with only one tested display device, and may also be in communication connection with multiple tested display devices at the same time, so that the aging test method provided by the present invention is executed on multiple tested display devices at the same time through one monitoring apparatus.
Step S200, sending a working state query instruction to the tested display equipment;
sending a working state query instruction to the tested display equipment, generating working state information after the tested display equipment receives the working state query instruction and returning the working state information to the monitoring device, judging whether the working state of the tested display equipment is abnormal during the aging test by the monitoring device according to the working state information, wherein the working state information can comprise: screenshot information and playing audio digital signals.
It can be understood that, the monitoring apparatus periodically sends a working state query instruction to the display device under test through a certain frequency (for example, 2 seconds) to monitor whether the display device under test has a fault or is abnormal during the aging test, in this embodiment, the working state query instruction is continuously sent to the display device under test through a certain frequency periodically, so that the display device under test periodically generates monitoring state information at a certain frequency, and meanwhile, the monitoring device periodically receives the working state information returned by the display device under test at a certain frequency, and determines whether the working state of the display device under test is abnormal during the aging test according to the working state information.
Correspondingly, the monitoring device may monitor aging tests of one display device under test, or simultaneously monitor aging tests of a plurality of display devices under test, when the monitoring device monitors aging tests of a plurality of display devices under test, step S200 is to send a working state query instruction to the plurality of display devices under test, the plurality of display devices under test generate respective working state information after receiving the working state query instruction and return the respective working state information to the monitoring device, the monitoring device receives the working state information generated by the plurality of display devices under test, and judges whether the working state of each display device under test during the aging tests is abnormal or not according to the working state information. It should be noted that, if the monitoring apparatus monitors a plurality of detected display devices, the operating state information should further include identification marks of the detected display devices, the identification marks correspond to the detected display devices one to one, and the monitoring apparatus can identify the detected display device corresponding to the generated state information according to the identification marks in the state information.
Step S30, receiving the working state information fed back by the tested display equipment, and judging whether the working state information accords with a preset rule;
the working state information may include voltage and current information, audio information, screenshot and the like of each working module, and the preset rule is a corresponding rule preset for each working module by a person skilled in the art according to fault information that may occur in the aging test process.
Referring to fig. 3, in an embodiment, step S30 includes:
step S300, judging whether screen capture information fed back by the display equipment to be tested according to the working state query instruction is received within preset time;
if screen capture information fed back by the tested display equipment is received within the preset time, executing the step S400, and judging whether the screen capture information is matched with a preset picture corresponding to the video information;
and if screen capture information fed back by the tested display equipment according to the working state query instruction is not received within the preset time, generating prompt information.
If the monitoring device does not receive the screen capture information fed back by the display equipment to be tested according to the working state query instruction within the preset time, the abnormal working of the display equipment to be tested can be determined, and the display equipment to be tested can possibly have host program unresponsiveness, crash and abnormal power failure, so that the display equipment to be tested can not feed back the screen capture information within the preset time. The generated prompt information can be specifically used for sending an early warning signal to the sound generating device and/or the light emitting device in real time, so that the sound generating device and/or the light emitting device can send a preset sound and/or a preset light source corresponding to the early warning prompt to execute the early warning prompt, and a worker can be reminded to further confirm the fault reason.
And if the screen capture information is not matched with the preset picture corresponding to the video information, executing the step S500 and generating prompt information.
Considering that the monitoring device may need to be placed in the aging room together, the distance between the monitoring device and the display device to be detected is closer, so that the reliability and the real-time performance of communication between the monitoring device and the display device to be detected are ensured as much as possible, and if the monitoring device is placed in the aging room, a worker may not easily obtain the early warning prompt of the monitoring device, or the worker may need to enter the aging room to know the early warning prompt. In an embodiment, install sound generating device and/or light emitting device or place the place that the staff conveniently learnt the early warning suggestion, monitoring device sends tip information through sound generating device and/or light emitting device in real time, makes sound generating device and/or light emitting device send the preset sound and/or predetermine the light source in order to carry out the early warning suggestion that corresponds with tip information, sound generating device and light emitting device be can with the monitoring device between the interactive device who communicates, sound generating device can include: a horn or a buzzer, the lighting device may comprise an indicator light or a display screen.
Further, step S500 is followed by: and sending the prompt information to an external server so that the external server sends the prompt information to a preset mobile terminal.
It can be understood that, when the working state of the display device under test is judged to be abnormal, the monitoring device may generate a working report form by the prompt information, and then upload the working report form to the external server for backup, so that a worker can log in the external server at any time to check the prompt information, and research and analyze the fault of the display device under test in the aging test according to the prompt information, or the external server sends the working report form to a preset mobile terminal, so that the worker can check the fault conveniently. The external server is, for example, an IOT platform, and the preset mobile terminal is, for example, a mobile phone. Of course, when the working state of the display device to be detected is determined to be abnormal, the prompt information may also be stored in a local cache or a hard disk of the monitoring device. The method solves the technical problems that the traditional display equipment to be tested needs to continuously monitor and store the prompt information output by the serial port of the display equipment to be tested for the staff to analyze the failure reason and the failure solving method during the aging test, improves the automation degree of the aging test, and does not need to manually record the state information of the display equipment to be tested during the aging test.
Further, when the monitoring device determines that the working state of the display device under test during the aging test is abnormal, the monitoring device may record the current time, generate a working report with the prompt information and the current time, and upload the working report to an external server for backup, so that a tester can log in the external server at any time to determine the time when the display device under test fails and perform research and analysis on the failure of the display device under test, and correspondingly, the working report may also be stored in a local cache or a hard disk of the monitoring device.
In the embodiment, the video information corresponding to the aging mode instruction is sent to the display equipment to be tested, so that the display equipment to be tested plays different video information according to different test requirements of users; judging whether the screen capture information of the feedback screen is matched with a preset picture corresponding to the video information or not, and generating prompt information to prompt a worker when the screen capture information of the feedback screen is not matched with the preset picture corresponding to the video information, so that the worker can observe the fault performance state in the test process of the test equipment without entering an aging room; through receiving the ageing mode instruction, control test equipment broadcast video information, feedback screen capture information, generate tip information etc. to realize automatic monitoring, save operations such as staff's patrolling and examining, periodic control, thereby practice thrift the human cost.
Referring to fig. 4, a flowchart of a third embodiment of the burn-in test method of the present invention is provided, based on the second embodiment, the step S400 includes:
and if the screen capture information is matched with a preset picture corresponding to the video information, executing the step S200 until the time length for sending the video information to the tested display equipment reaches the preset time length, and stopping sending the video information and the working state query instruction to the tested display equipment.
If the time length for sending the video information to the tested display equipment reaches the preset time length, no abnormity is detected, the aging test is qualified, and the tested display equipment preliminarily meets the delivery qualification; and if the time length for sending the video information to the tested display equipment does not reach the preset time length and the abnormal condition is monitored, the aging test is unqualified and the tested display equipment does not have delivery qualification, and the tested display equipment with problems needs to be returned to engineering personnel for research and analysis. The preset time can be set by a person skilled in the art according to actual conditions.
It can be understood that the sending of the video information and the working state query instruction to the display device to be tested is stopped until the time length for sending the video information to the display device to be tested reaches a preset time length, or the sending of the video information and the working state query instruction to the display device to be tested is stopped until a termination instruction of the aging test input by a user is received, and the termination instruction may be received by the display device to be tested or received by the monitoring device.
It should be noted that, if the screen capture information matches the preset picture corresponding to the video information, step S200 is executed at intervals of the preset query time, that is, the monitoring apparatus periodically sends a working state query instruction to the display device under test through a certain frequency. It can be understood that if the monitoring frequency is too low, the accuracy of monitoring the tested display device will be reduced, because the tested display device may automatically recover to normal when an abnormality occurs during the aging test, and there is only a short fault problem, for example, the tested display device automatically restarts to return to normal after suddenly turning to the blue screen or recovers to a normal picture after suddenly turning to the blue screen, and at this time, if the monitoring frequency is too low, the fault of the blue screen or automatic restart will not be detected. Of course, if the monitoring frequency is too high, the operation load of the monitoring device and the display device to be detected is increased, especially the operation load of the monitoring device is increased, and the operation load is too high, which will pose a higher challenge to the software and hardware of the execution terminal. The monitoring frequency can be set by a person skilled in the art according to actual needs, and the embodiment is not particularly limited.
In this embodiment, when the screen capture information matches the preset picture corresponding to the video information, the step of sending the working state query instruction to the display device to be tested is executed, until the time length for sending the video information to the display device to be tested reaches the preset time length, the method for sending the video information to the display device to be tested is stopped, the working state of the aging test of the display device to be tested can be periodically monitored at a certain frequency, the display device to be tested with abnormal working state can be timely found, the labor cost of the aging test is saved, and the product quality is also improved.
Referring to fig. 5, a partial flowchart of a fourth embodiment of the burn-in test method according to the present invention is shown, wherein based on the second embodiment, the step S400 includes:
step S410, if screen capture information fed back by the display device to be tested is received within a preset time, determining instruction sending time according to a working state query instruction corresponding to the screen capture information, and updating a preset picture into an image frame of a time node corresponding to the instruction sending time in the video information;
and after the tested display equipment receives the working state query instruction, screenshot is carried out on the current display interface, and the screenshot is fed back to the monitoring equipment. It can be understood that the video information is sent to the display device to be tested by the monitoring device in real time for playing, so that the monitoring device stores the video information, and therefore the monitoring device only needs to record the sending time of the working state query instruction corresponding to the screen capture information and update the preset picture to be the image frame of the sending time at the corresponding time node in the test program. The communication time difference between the sending of the working state query instruction and the receiving of the screen capture information is very small and can be almost ignored.
Step S420, analyzing the difference degree between the screenshot information and the preset picture, and judging whether the difference degree exceeds a preset value;
if the difference degree exceeds a preset value, the working state of the tested display equipment is determined to be abnormal, and if the working state of the tested display equipment is determined to be abnormal, corresponding prompt information is generated. And if the difference does not exceed a preset value, determining that the working state is normal. For example, when the display device under test has problems of blue screen, snowflake, image jitter, scrolling, image color cast, etc. during the aging test, the image of the current screen is captured and compared with the preset image, so that a large difference is easily compared, and the working state is determined to be abnormal.
According to the embodiment, the detected display equipment is subjected to picture monitoring periodically at a certain frequency during the aging test, the related faults of the detected display equipment during the aging test are found in time, the early warning prompt is carried out, the state information of the related faults is stored for workers to check and analyze at any time, the quality of products is further guaranteed, the automation degree of the aging test is improved, and the cost is saved.
Referring to fig. 6, a flowchart of a fifth embodiment of the burn-in test method according to the present invention is shown, wherein based on the first embodiment, the step S30 further includes:
step S700, judging whether a playing audio digital signal fed back by the display equipment to be tested according to the working state inquiry instruction is received within a preset time;
and if the playing audio digital signal fed back by the tested display equipment is not received within the preset time, generating prompt information. It is understood that in the present embodiment, audio information is included in the video information.
Step S800, if a playing audio digital signal fed back by a display device to be tested is received within a preset time, judging whether the playing audio digital signal is matched with a preset audio corresponding to the video information;
and if the playing audio digital signal is not matched with the preset audio corresponding to the video information, generating prompt information. It should be noted that, the playing audio digital signal is an audio electrical signal of the motherboard of the display device under test, which is different from the collection of the analog signal sent by the speaker, and the audio electrical signal is a digital signal, the communication mode between the monitoring device and the display device under test is preferably a wired transmission mode, which not only can improve the communication efficiency, reduce the communication fault or abnormality between the monitoring device and the display device under test, but also can facilitate the monitoring device to collect the audio electrical signal of the motherboard of the display device under test, and can collect the audio electrical signal of the motherboard of the display device under test by connecting the monitoring device to the serial port of the audio output of the display device under test through a wire. It can be understood that, when the abnormal states of silence, excessive noise in sound, sound amplitude deviation, sound frequency deviation and the like occur during the aging test of the display device to be tested, the difference between the playing audio digital signal and the preset audio corresponding to the video information is relatively large, and the monitoring device detects that the playing audio digital signal is not matched with the preset audio corresponding to the video information, and generates the prompt information.
Further, the step of determining whether the playing audio digital signal matches a preset audio corresponding to the video information includes:
if a playing audio digital signal fed back by the tested display equipment is received within the preset time, determining the instruction sending time according to a working state query instruction corresponding to the playing audio digital signal, and updating the preset audio to be an audio frame of the corresponding time node of the instruction sending time in the test program; and analyzing the difference degree between the played audio digital signal and the audio frame, and judging whether the difference degree exceeds a preset threshold value.
If the playing audio digital signal is not matched with the preset audio corresponding to the video information, the step of generating the prompt information comprises the following steps: and if the difference exceeds a preset threshold value, generating prompt information.
This embodiment is through the sound monitoring to being surveyed display device when aging testing with certain frequency periodicity, in time discovers the relevant trouble that is being surveyed display device and appears when aging testing to the warning suggestion, the status information of relevant trouble is preserved and is looked over and the analysis at any time for the staff, has further ensured the quality of product, has promoted aging testing's degree of automation, has saved the cost.
Referring to fig. 7, a flowchart of a sixth embodiment of the burn-in test method of the present invention is shown, where the burn-in test method further includes:
step S910, receiving a voltage fluctuation test instruction, and starting to sequentially control a power supply module to supply power or cut off power to the display equipment to be tested in a preset period so as to enable the display equipment to be tested to be powered on and powered off alternately;
and sequentially controlling the power supply module to supply power or cut off power to the display device to be tested according to a preset period, for example, supplying power to the display device to be tested for 20 minutes, cutting off power for two minutes, and circulating for 100 periods or lasting for 48 hours. It should be noted that, the monitoring device sends the communication signal to the power supply device of the display device to be tested, so that the power supply device performs the power supply/power off processing operation on the display device to be tested in a preset period, where the power supply device should be the power supply device capable of communicating with the monitoring device. Preferably, the monitoring device directly supplies power to the display device to be detected, that is, the monitoring device has a power output module, one or more display devices to be detected connect their respective power lines with the power output module of the monitoring device, and the monitoring device directly implements the operation of performing power supply/power off processing of a preset period on the display device to be detected.
Step S920, sending a power-on state query instruction to the display device to be tested within the power supply time period of the display device to be tested in a preset cycle;
it can be understood that, when the voltage fluctuation test is performed on the display device under test, the monitoring of the display device under test by the monitoring apparatus should be within the power supply period, that is, the sending of the power-on state query instruction should be during the power supply period, for example, the monitoring apparatus controls the display device under test to be powered on for 20 minutes, powered off for two minutes, and cycled back and forth for 100 cycles, so that the monitoring of the operating state of the display device under test should be during the 20-minute period of power supply.
Step S930, determining whether circuit information fed back by the display device under test according to the power-on state query instruction is received within a preset time;
the circuit information may include a voltage value, a current value, and electric power in the circuit loop of the display device to be tested, and the circuit information may be one of them, or a combination of several of them, and is preferably the current value in the circuit loop.
And step S940, if the circuit information fed back by the display equipment to be tested is not received within the preset time, prompt information is generated.
It can be understood that, if the circuit information fed back by the display device under test is not received within the preset time, it may be determined that the working state of the display device under test is abnormal, and the abnormal working state may be a short circuit or an abnormal power failure caused by a circuit burnout of the display device under test during the aging test, where the generating of the prompt information may include: the sound production device and/or the light emitting device are/is enabled to send out preset sound and/or a preset light source corresponding to the early warning prompt to execute the early warning prompt by sending early warning signals to the sound production device and/or the light emitting device in real time, so that a worker is reminded to further confirm related faults.
