Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
At present, when faults such as optical machine problems, poor focusing and the like occur to a projector, the projector is not intelligent enough, equipment faults cannot be detected by self, the faults of the projector can be found only by customer complaints of taking an elevator or routing inspection of maintenance personnel, and the fault reasons can be known only by the maintenance personnel after the maintenance personnel check the faults. This leaves a bad impression on the customer and the inspection by the maintenance personnel is very wasteful of human resources.
In this embodiment, if the projector projects a red image, the red LED lamp in the projector emits light to project the red image, so that the projector checks the identification condition of the two-dimensional code by projecting the two-dimensional code having a color corresponding to the LED lamp, thereby knowing whether the projector has a failure. The problem of projector among the prior art not enough intelligent, unable self-checking out equipment trouble is solved, effectively improve customer experience and reduce the waste of manpower resources.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, in an embodiment of the present invention, a method for checking a projector fault includes:
s101, controlling a projector to sequentially put preset two-dimensional codes corresponding to the LED lamps of each color of the projector, wherein the preset two-dimensional codes correspond to the LED lamps;
preferably, the LED lamps of the respective colors are three primary color LED lamps, i.e., red, green and blue, so that when other colors are projected, the other colors can be adjusted according to the ratio of each of the three primary colors, thereby enabling the projector to project a color image. If the image projected by the projector has color imbalance and the like, the problem of one or more colors of the three-color LED lamp is shown, so that the projector can know whether the projector has faults or not only by self-checking whether the color of the image projected by the three-color LED lamp is in the problem or not.
The figure color of the preset two-dimensional code is different from the background color, such as a white background red two-dimensional code, so that a clear figure outline is provided to facilitate a projector to scan the figure of the two-dimensional code. The preset two-dimensional code corresponds to the LED lamps of all colors one by one, and the corresponding relation exists between the figure shape of the preset two-dimensional code (the figure of the preset two-dimensional code is abbreviated as below) and the LED lamps, or the corresponding relation exists between the figure color of the preset two-dimensional code (the color of the preset two-dimensional code is abbreviated as below) and the LED lamps.
For example, the preset two-dimensional code has a corresponding relationship with the LED lamp: two-dimensional code figure A corresponds red LED lamp, and two-dimensional code figure B corresponds green LED lamp, and two-dimensional code figure C corresponds blue LED lamp. The color of the preset two-dimensional code corresponds to the LED lamp: the red LED lamp corresponds red two-dimensional code, and green LED lamp corresponds green two-dimensional code, and blue LED lamp corresponds blue two-dimensional code. Specifically, when the projector puts the red two-dimensional code, the red two-dimensional code is imaged by emitting light from the red LED lamp, so that when the red two-dimensional code cannot be identified, that is, the red LED lamp does not emit light, it is indicated that the red LED lamp has a problem, and thus the projector self-checking fault is realized.
In an embodiment, the controlling the projector to sequentially release the preset two-dimensional codes respectively corresponding to the LED lamps of each color of the projector includes: and under the condition that the elevator is unloaded, controlling the LED lamps of all colors to automatically and sequentially put in the corresponding preset two-dimensional codes, wherein the colors of the preset two-dimensional codes are the same as the colors of the LED lamps.
Specifically, the LED lamps of each color are controlled to sequentially release the corresponding preset two-dimensional codes, for example, the red LED lamps are controlled to release the preset red two-dimensional codes first, then the green LED lamps are controlled to release the preset green two-dimensional codes, and all the LED lamps sequentially release the corresponding preset two-dimensional codes; further, the red two-dimensional code can be automatically switched to the green two-dimensional code after being recognized (including recognition success or recognition failure), so that the time interval for putting two preset two-dimensional codes in each LED lamp is shorter, and the time for putting the preset two-dimensional codes in the LED lamps of each color can be preset.
Above-mentioned empty load of elevator does not have article or biology for in the elevator, and preferably, the empty load of elevator does not have the passenger for in the elevator to only check whether the projector breaks down when not having the passenger in the elevator, other moments then put in the elevator advertisement as usual, can not influence like this the projector and put in the advertisement to the passenger, accord with the use scene of elevator more.
Optionally, when the elevator door of the elevator does not act within a preset time, the LED lamps of all colors are controlled to automatically and sequentially put in the corresponding preset two-dimensional codes.
The national standard stipulates that the time of single operation of the elevator cannot exceed 60 seconds, so the preset time is more than 60 seconds, such as 2 minutes, namely, no action of the elevator door within 2 minutes can ensure that no people exist in the elevator. The actions of the elevator door comprise opening actions and closing actions, preferably the opening actions of the elevator door within preset time are detected, so that the elevator door can be prevented from being opened by passengers for a long time when carrying goods, and the elevator door is not detected to be closed, so that the condition that the two-dimensional code is put in when the elevator door is opened, and an invalid inspection process is caused is avoided.
Optionally, when the bearing of the elevator is within a preset range, the LED lamps of all colors are controlled to automatically and sequentially put in the corresponding preset two-dimensional codes. The above-mentioned predetermined scope is the intrinsic weight scope of elevator when the elevator does not operate and the elevator is unloaded, if intrinsic weight is 100KG, the error is 2KG, then the predetermined scope is 100 2 KG.
Optionally, when human infrared rays are not detected in the elevator, the LED lamps of all colors are controlled to automatically put in the preset two-dimensional codes corresponding in sequence. The human body can release infrared rays within a certain wavelength range, so that whether the human body infrared rays exist in the elevator is detected through the human body infrared sensing device. It should be noted that the elevator advertisement is seen by the passengers, so that the preset two-dimensional code is delivered for identification even if the elevator has articles and no passenger.
S102, identifying the imaging two-dimensional codes of each preset two-dimensional code after being projected and imaged by the projector, and judging whether all the successfully identified imaging preset two-dimensional codes contain the preset two-dimensional codes corresponding to all the LED lamps;
the imaging two-dimensional code is an imaging graph of a preset two-dimensional code projected by a projector, and the corresponding imaging two-dimensional code can be formed by the preset two-dimensional code projected by the LED lamp corresponding to each color. Identifying the imaged two-dimensional code may include identifying a color and/or a graphic of the imaged two-dimensional code. According to the actual projection condition of the LED lamp, the imaging two-dimensional code may be complete in graphic and color display, incomplete in graphic display, incapable of displaying color and capable of displaying blank images.
The preset two-dimensional codes corresponding to the LED lamps have the same or different graphs, so that the imaging two-dimensional codes corresponding to the LED lamps have the same or different images. Specifically, when the color of the imaged two-dimensional code needs to be identified, the figures of the imaged two-dimensional code are the same, and when the color of the imaged two-dimensional code does not need to be identified, the figures of the imaged two-dimensional code are different.
Furthermore, the projector is provided with a camera, the camera scans and identifies the imaging two-dimensional codes of all colors, a daily check list is established, and the time, the type of the two-dimensional codes (namely the preset two-dimensional codes corresponding to the LED lamps of all colors) and the identification result of each identification are recorded in the daily check list, so that maintenance personnel can check the self-checking record of the projector conveniently.
S103, if not, judging that the projector has a fault;
such failures include damage to one or more of the color LED lamps and poor projector focus.

The color of the imaging two-dimensional code is the graphic color of the imaging two-dimensional code. Specifically, the LED lamps of each color are controlled to sequentially throw in the corresponding preset two-dimensional codes, when a certain LED lamp fails or a projector is in poor focus, the corresponding imaging two-dimensional codes are displayed incompletely or only show the shadow outline of the preset two-dimensional codes, and only show the shadow, the imaging two-dimensional codes cannot be scanned, the image of the imaging two-dimensional codes cannot be identified successfully if the image of the imaging two-dimensional codes is displayed incompletely, but whether the complete preset two-dimensional codes are projected or not, the camera sequentially obtains the preset two-dimensional code graphs thrown in the LED lamps at preset time intervals, the colors of the imaging two-dimensional codes are identified through a color identification technology, the identified colors of the imaging two-dimensional codes are recorded, and because the number of the colors of the LED lamps is the same as the number of the colors of the preset two-dimensional codes, when the LED lamps work normally, the identified colors of the imaging two-dimensional codes should include the colors of all the LED lamps, therefore, it is determined whether the color of the first LED lamp included in all the LED lamps is included in all the recognized colors, that is, whether the color of all the LED lamps is included in all the recognized colors.
Further, if not, determining that the projector has a fault, including: and if the identified colors of all the imaging two-dimensional codes do not contain the color of the first LED lamp, judging that the first LED lamp has a fault. The colors of all the LED lamps are required to be contained in all the identified colors, and when the first LED lamp is burnt out and the like, the preset two-dimensional code corresponding to the colors cannot be put in, so that the color of the first LED lamp corresponding to the preset two-dimensional code cannot be identified.
Further, after the above-mentioned judging whether the colors of the identified imaging two-dimensional codes include the color of the first LED lamp, the method includes: if the identified colors of all the imaging two-dimensional codes comprise the colors of all the LED lamps, identifying the graph of each imaging two-dimensional code, and judging whether the graphs of all the imaging two-dimensional codes are failed to be identified, wherein the graphs of the imaging two-dimensional codes corresponding to the LED lamps of each color are the same; and if so, judging that the projector is in poor focus.
The graph of the imaging two-dimensional code is in the shape of the graph of the imaging two-dimensional code. In this embodiment, the identified colors of all the imaged two-dimensional codes include the colors of all the LED lamps, that is, the LED lamps in the projector all operate normally, so that whether the focus of the projector is in poor focus is further checked. Specifically, all the imaging two-dimensional codes are identified, the figures of all the imaging two-dimensional codes are the same, the colors of the imaging two-dimensional codes correspond to the colors of the LED lamps one by one, and when all the two-dimensional codes with different colors of the same figure fail to be identified, poor focusing of the projector is indicated. The same graph can ensure that only one variable is provided, so that the judgment result is more accurate.
It should be noted that the above-mentioned embodiment is not taken as a means for limiting the present invention, and those skilled in the art should understand that in other embodiments, the graphic color and the graphic shape of each imaged two-dimensional code may also be simultaneously recognized to simultaneously check whether the LED lamp and the focus of the projector are faulty, which is not described herein again.
In a specific embodiment, the identifying the graph of each of the imaged two-dimensional codes includes: analyzing url addresses corresponding to the preset two-dimensional codes; respectively sending an access request to each url address; receiving Http state codes returned by the url addresses according to the access requests respectively; if the Http state code is a preset value, judging that the imaging two-dimensional code corresponding to the Http state code is successfully identified; and if the Http state code is not a preset value, judging that the imaging two-dimensional code corresponding to the Http state code fails to be identified.
The preset value is 200, that is, the Http status code 200 indicates that the server corresponding to the url address successfully receives the access request, and then the imaging two-dimensional code corresponding to the url address is successfully identified. And when the Http state code is not a preset value, such as 400 and 404, the server corresponding to the url address does not respond to the access request, and the imaging two-dimensional code corresponding to the url address fails to be identified.
In an embodiment, the identifying the imaging two-dimensional code after each preset two-dimensional code is projected and imaged by the projector, and determining whether all the successfully identified imaging two-dimensional codes include the preset two-dimensional codes corresponding to all the LED lamps includes: and identifying the graph of the imaging two-dimensional code of each color, and judging whether the graph of each imaging two-dimensional code is successfully identified, wherein the graphs of the preset two-dimensional codes corresponding to the LED lamps are different.
In the embodiment, each color of the LED lamp corresponds to a two-dimensional code with a pattern different from other preset two-dimensional code patterns, namely the patterns of the imaging two-dimensional code are different, whether focusing of the LED lamp and the projector fails or not is judged according to the identification result by only identifying the pattern of the imaging two-dimensional code, the color of the imaging two-dimensional code does not need to be identified, and the identification speed is higher.
Specifically, if the determination result is no, the determining that the projector has a fault includes: if the pattern recognition of the first imaging two-dimensional code fails, judging that an LED lamp corresponding to the first imaging two-dimensional code fails, wherein the first imaging two-dimensional code is contained in all the imaging two-dimensional codes; and if the identification of all the images of the imaging two-dimensional code fails, judging that the projector is in poor focus. When the identification of part of the imaging two-dimensional codes fails, the fault of the LED lamp corresponding to the preset two-dimensional codes which fail to be identified is indicated, and when all the imaging two-dimensional codes fail to be identified, the poor focusing of the projector is indicated, wherein when the focusing of the projector is poor, the poor focusing caused by the faults of part or all the LED lamps can be caused, the poor focusing caused by other reasons of lens loosening lamps can be caused, and the poor focusing caused by the faults of part or all the LED lamps and the lens loosening of the projector can be caused at the same time.
And S104, sending the information that the projector has the fault to a background terminal.
When the projector is detected to have a fault, a message that the projector has the fault is generated, and the projector is in communication connection with the background terminal to send the message to the background terminal, so that maintenance personnel are informed of on-site maintenance, and the maintenance personnel do not need to perform daily routing inspection. Furthermore, the projector records the inspection result after each self-inspection, and the user can check the inspection result of each self-inspection of the projector through the background terminal.
