Referring to fig. 4, an embodiment of the present application shows a tiled screen, including a touch frame, a first screen 3, and a second screen 4;
at least one edge of the first screen 3 and at least one edge of the second screen 4 are spliced to form a combined screen, and the touch frame is arranged on the periphery of the combined screen to form the spliced screen;
the touch frame at least comprises a first edge and a second edge, wherein the first edge and the second edge are respectively provided with a signal transmitting tube 1 and a signal receiving tube 2 which correspond to each other.
In this embodiment, the lengths of the two opposite sides of the first screen 3 and the second screen 4 are equal, and the side at the joint is defined as the joint side. A plurality of signal transmitting tubes 1 are arranged on the touch frame on one side perpendicular to the splicing edge, and a plurality of signal receiving tubes 2 are arranged on the touch frame on the other side perpendicular to the splicing edge. Each signal receiving tube 1 is provided with a signal receiving tube 2 which is opposite to the signal receiving tube. The touch frame is designed by adopting an adhesive tape, a plurality of holes are formed in the touch frame, and each hole is used for fixing one or more signal transmitting tubes/signal receiving tubes.
Referring to fig. 1, in an embodiment of the present application, a method for detecting flatness of a tiled screen is provided, where a signal transmitting tube adjacent to a first screen 3 and arranged on a touch frame is a first transmitting tube, a signal receiving tube adjacent to the first screen 3 and arranged on the touch frame is a first receiving tube, and a signal receiving tube adjacent to a second screen 4 and arranged on the touch frame is a second receiving tube, and the method for detecting flatness of a tiled screen includes:
s1, controlling the first transmitting tube to send out an optical signal;
s2, reading a first signal value received by the first receiving tube and a second signal value received by the second receiving tube, wherein when the first screen and the second screen 4 are connected smoothly, both the first receiving tube and the second receiving tube can receive the light signal emitted by the first emitting tube;
s3, if the first signal value and the second signal value accord with a preset rule, judging that the first screen and the second screen 4 are spliced flatly;
and S4, displaying specified information on the first screen 3 or the second screen 4, wherein the specified information is used for indicating a user that the spliced screen is spliced smoothly.
In this embodiment, specifically, referring to fig. 4, the whole display screen is formed by combining two screens, the two screens are the first screen 3 and the second screen 4 respectively, the widths of the first screen 3 and the second screen 4 are the same, and the lengths of the first screen 3 and the second screen 4 may be different or the same. The first screen 3 and the second screen 4 are assembled together at the sides of their width to form a larger combined screen, so that the width of the assembled combined screen is also equal to the width of the first screen 3/the second screen 4. Meanwhile, signal receiving tubes are arranged on the wide edges of the connecting part of the first screen 3 and the second screen 4, wherein 1 points to the transmitting tube and 2 points to the receiving tube in the figure 4. Specifically, a first receiving tube is arranged at a position, close to the first screen 3 and close to the second screen 4, of the touch frame, and a second receiving tube is arranged at a position, close to the second screen 4 and close to the first screen 3, of the touch frame. Meanwhile, a first transmitting tube for transmitting optical signals is arranged on the corresponding wide side, close to the first screen 3, of the touch frame, and the first transmitting tube is opposite to the first receiving tube; in addition, because the first receiving tube and the second receiving tube are close to each other, the optical signal emitted by the first transmitting tube also has a certain scattering function, so that most of the optical signal emitted by the first transmitting tube can be received by the second receiving tube. After the first screen 3 and the second screen 4 are connected, a user sends out an optical signal for testing flatness, at the moment, a first transmitting tube on the first screen 3 sends out the optical signal, a first receiving tube at the opposite end of the first transmission of the first screen 3 receives the optical signal, and a first signal value is generated according to the strength of the received optical signal, and because the first receiving tube and the first transmitting tube are both positioned on the first screen 3, the whole screen is flat, the strength of the optical signal received by the first receiving tube is fixed; meanwhile, the second receiving tube on the second screen 4 also receives the optical signal, and generates a second signal value according to the intensity of the received optical signal. Then, the processor acquires the first signal value and the second signal value at the same time, and judges the installation flatness of the first screen 3 and the second screen 4 according to the difference value of the two signal values. If the difference value is smaller, the normal deviation range of the light signals received by the second receiving tube is obtained, the fact that the screens of the first screen 3 and the second screen 4 are located on the same plane is indicated, and the total screen is spliced flatly; if the difference value is larger, the deviation of the light signals received by the second receiving tube is larger, which indicates that the screens of the first screen 3 and the second screen 4 are not in the same horizontal plane, and adjustment is required.
It should be noted that, as long as the first screen 3 and the second screen 4 are not flat, because the first transmitting tube is only installed close to the first screen 3, the first receiving tube is installed close to the first screen 3, and the second receiving tube is installed close to the second screen 4, under the condition that the first screen 3 is flat, the first receiving tube is always over against the first transmitting tube, and the corresponding first signal value is always greater than the second signal value.
The second receiving tube receives weak optical signals sent by the first transmitting tube, and the height of the first transmitting tube is possibly higher than that of the second receiving tube because the first screen 3 is higher than the second screen 4, so that the upper end part of the second receiving tube can receive the optical signals, the optical signals received by the second receiving tube are weaker, and the generated second signal value is smaller; of course, there is another situation that if the first screen 3 is lower than the second screen 4, the signal emitted from the first transmitting tube is partially blocked by the edge of the second screen 4 when facing the second receiving tube, which also results in a weaker light signal received by the second receiving tube and a smaller value of the generated second signal. Therefore, according to the magnitude of the first signal value and the second signal value, whether the first screen 3 and the second screen 4 are spliced smoothly can be judged. In another specific embodiment, a second transmitting tube is also arranged on the touch frame close to the position, opposite to the second receiving tube, on the second screen 4, when whether the splicing is smooth is detected, after the first transmitting tube sends out the optical signal, the second transmitting tube is controlled to send out the optical signal, then a third signal value received by the first receiving tube on the first screen 3 and a fourth signal value received by the second receiving tube on the second screen 4 are read, whether the first screen 3 and the second screen 4 are spliced smoothly is judged according to the third signal value and the fourth signal value, and the judgment method can also be used for calculating the difference value between the third signal value and the fourth signal value within a certain range and judging that the first screen 3 and the second screen 4 are spliced smoothly. In addition, the first screen 3 and the second screen 4 can be spliced smoothly when the two signal values meet the preset rule as a result of the two times. The typeface that the installation was successful is then displayed on the first screen 3 or the second screen 3 so that the user knows that the splice is flat.
The first transmitting tube and the second transmitting tube are respectively a signal transmitting tube, and the first receiving tube and the second receiving tube are respectively a signal receiving tube.
In one embodiment, the number of the first transmitting tubes is N (N is a positive integer greater than 1, such as 2 or 3) signal transmitting tubes, and the number of the corresponding first receiving tubes is also N signal transmitting tubes. During detection, each signal transmitting tube of the first transmitting tubes is controlled to sequentially transmit optical signals, and the corresponding signal receiving tube of each first receiving tube and the corresponding signal receiving tube of the second receiving tube both receive the optical signals for N times, so that the first receiving tubes obtain N optical signals, and the second receiving tubes also obtain N optical signals. And then, the optical signals are respectively calculated to obtain a corresponding first signal value and a corresponding second signal value. In one embodiment, the first signal value is calculated by: respectively reading the optical signals received by each first receiving tube, deleting the optical signals with the signal intensity lower than a specified first intensity threshold value, and calculating the average value of the rest optical signals to obtain a first signal value; the second signal value is calculated by: and respectively reading the optical signals received by each second receiving tube, deleting the optical signals with the signal intensity lower than the specified second intensity threshold value, and calculating the average value of the rest optical signals to obtain a second signal value. The error caused by the damage of the signal transmitting tube or the signal receiving tube can be avoided.
In one embodiment, the step of determining that the first screen 3 and the second screen 4 are smoothly spliced if the first signal value and the second signal value meet a preset rule includes:
s31, calculating the difference between the first signal value and the second signal value to obtain a signal difference value;
s32, judging whether the signal difference value is smaller than a preset signal threshold value;
and S33, if yes, judging that the first screen 3 and the second screen 4 are spliced flatly.
In this embodiment, the processor reads the first signal value and the second signal value at the same time, and then calculates the difference between the first signal value and the second signal value, since the first receiving pipe is definitely located at the same level as the first transmitting pipe, and the first receiving pipe is directly opposite to the first transmitting pipe, the signal intensity received by the first receiving pipe is definitely higher than that received by the second receiving pipe, and the corresponding first signal value is greater than the second signal value. At this time, the second signal value is subtracted from the first signal value to obtain a signal difference value. Then, a preset signal threshold value is called, and the signal threshold value is a standard threshold value used for judging whether the total screen is flat or not. If the signal difference is smaller than the preset signal threshold, it is indicated that the signal intensities that the first receiving tube and the second receiving tube can receive are very close, the second receiving tube and the first receiving tube are on the same horizontal plane, and the corresponding second screen 4 and the corresponding first screen 3 are also on the same horizontal plane, and it is determined that the first screen 3 and the second screen 4 are spliced flatly.
In one embodiment, before the step of determining whether the signal difference is smaller than a preset signal threshold, the method includes:
s301, acquiring a screen width value;
and S302, multiplying the screen width value by a preset threshold coefficient to obtain the signal threshold.
In this embodiment, if the width of the screen is large, that is, the first transmitting tube and the first receiving tube are far apart, that is, the signal transmitted by the first transmitting tube is received by the first receiving tube and the second receiving tube after a long distance, and due to the divergence of the optical signal, the influence of the first receiving tube on the intensity of the received signal of the first transmitting tube is relatively low; that is, if the first screen and the second screen are flatly located on the same horizontal plane, the farther the first transmitting tube and the first receiving tube are apart from each other, the closer the signal intensities received by the first receiving tube and the second receiving tube are. The distance between the first transmitting tube and the first receiving tube is the width of the screen. Therefore, it is necessary to associate with the width of the screen when setting the signal threshold. Specifically, before the step S33 is executed, a screen width value of the screen width is first acquired, and then the screen width value is multiplied by a preset threshold coefficient to obtain a signal threshold. When the screens with different widths are assembled, the corresponding signal threshold values can be obtained more accurately, and whether the installation of the corresponding judged first screen 3 and the second screen 4 is smooth or not is more accurate.
In one embodiment, the step of obtaining the screen width value includes:
s311, reading the attribute information of the first screen 3, and calling out the screen width value.
In the present embodiment, since the widths of the first screen 3 and the second screen 4 are both the same, the widths of the total screens formed by the corresponding combinations are also the same, and the width of the screen is the inherent attribute information of the screen. Therefore, in the present embodiment, the attribute information of the first screen 3 can be directly read, and then the corresponding screen width value is called. In other embodiments, the attribute information of the second screen 4 may be read, and the screen width value may be called. The widths of the first screen 3 and the second screen 4 are the same, and thus the screen width value for calling either screen is the same.
In one embodiment, the step of obtaining the screen width value includes:
s321, calculating the screen width value according to the time of the first transmitting tube sending the optical signal and the time of the first receiving tube receiving the optical signal.
In this embodiment, the first emission tube and the first receiving tube are respectively located on two width sides of the first screen 3, and face each other, so that the distance between the first receiving tube and the first emission tube is equal to the width of the first screen 3. On the basis, when the screen width value is calculated, the first transmitting tube and the first receiving tube are used as infrared distance measuring sensors, and the distance between the first transmitting tube and the first receiving tube is calculated by utilizing the time of the first transmitting tube for transmitting the light signal and the time of the first receiving tube for receiving the light signal, so that the screen width value is obtained. The calculation process specifically includes controlling the first transmitting tube to send the optical signal, recording time for sending the optical signal as first time, then obtaining time for receiving the optical signal by the first receiving tube, recording as second time, subtracting the first time from the second time to obtain a time difference value, and multiplying the time difference value by the transmission speed of the optical signal to obtain a screen width value. In one embodiment, the first time is recorded when the step S1 is executed, and the second time is recorded when the step S2 is executed. Only need once to emit optical signal, then when judging, calculate signal difference and signal threshold according to first time and second time earlier, judge again whether first screen 3 and second screen 4 splice and level, can improve the utilization efficiency of first transmitting tube.
In one embodiment, the step of reading the first signal value received by the first receiving tube on the first screen and the second signal value received by the second receiving tube on the second screen 4 is followed by:
and S4, if the first signal value and the second signal value do not accord with the preset rule, judging that the first screen 3 and the second screen 4 are not spliced flatly, controlling the first emission tube to continuously work, and displaying the first signal value and the second signal value on the first screen and/or the second screen 4.
In this embodiment, when it is determined that the first screen 3 and the second screen 4 are not joined smoothly, the adjustment needs to be continued, and in general, the area of the first screen 3 is larger than that of the second screen 4, and the installation of the second screen 4 is usually finely adjusted based on the first screen 3. In the process of adjustment, the worker is difficult to adjust because the naked eye can hardly find out that the plane of the second screen 4 is higher than the plane of the first screen 3 or lower than the plane of the first screen 3. In the scheme, the first signal value and the second signal value are displayed on the first screen 3 and/or the second screen 4, so that a worker can see the two signal values in real time during adjustment, the second signal value can change due to the flatness of the first screen and the second screen 4 because the first signal value is fixed and unchangeable, and the difference between the second signal value and the first signal value is smaller as the two screens are flatter. When the staff adjusts the second screen 4, the closed loop adjustment can be performed according to the difference between the two signal values displayed on the first screen 3 and/or the second screen 4, and if the second screen 4 is finely adjusted downwards and the difference between the first signal value and the second signal value becomes larger, it indicates that fine adjustment is required upwards. By displaying the two signal values on the first screen 3 and/or the second screen 4, the flatness of the first screen and the second screen 4 can be adjusted more quickly in a direction of a worker.
In one embodiment, the spliced screen at least comprises a first screen 3 and a second screen 4, the spliced screen comprises two wide sides and two long sides, the first transmitting tube, the first receiving tube and the second receiving tube are located on a touch frame corresponding to the wide sides, and a fifth transmitting tube and a fifth receiving tube are respectively arranged on the touch frame corresponding to the two long sides; if the first signal value and the second signal value meet a preset rule, after the step of judging that the first screen 3 and the second screen 4 are spliced flatly, the method comprises the following steps of:
s34, controlling the fifth transmitting tube to emit light signals, wherein the direction of the light signals emitted by the fifth transmitting tube is perpendicular to the direction of the light signals emitted by the first transmitting tube;
s35, reading a fifth signal value received by a fifth receiving tube;
s36, judging whether the fifth signal value is larger than a preset transverse signal threshold value or not;
and S37, if yes, verifying that the spliced screen is spliced smoothly.
In this embodiment, referring to fig. 5 and fig. 6, the spliced screen is composed of the first screen 3 and the second screen 4, and of course, a third screen may be added, and the like, which are not limited too much. The widths of the screens (for example, N screens) are equal, and the long sides of the screens are sequentially assembled to form a spliced screen. The tiled screen has the same meaning as the general screen described above. The wide sides of the screens extend sequentially to form the wide sides of the spliced screen, and the two screens (the first screen 3 and the Nth screen) from head to tail are the long sides of the spliced screen. After a first signal value and a second signal value are detected by a first transmitting tube arranged on the wide edge of the first screen 3 and accord with a preset rule, the first screen 3 and the second screen 4 are judged to be spliced flatly, then the second screen 4 and the third screen are continuously judged to be spliced flatly, and the like, after every two adjacent screens are sequentially verified to be spliced flatly by the transmitting tube and the receiving tube arranged on the wide edge, more accurate detection and verification are further performed. And a fifth transmitting tube is arranged on the touch frame corresponding to the long edge of the Nth screen. So as to verify whether the spliced screen is spliced smoothly. And controlling the fifth transmitting tube to emit an optical signal, enabling the fifth receiving tube to receive the optical signal and generate a fifth signal value, then comparing the fifth signal value with a preset transverse signal threshold, and if the fifth signal value is greater than or equal to the transverse signal threshold, indicating that the optical signal emitted by the fifth transmitting tube passes through the first screen 3 and the second screen 4.
To sum up, the flatness detection method for the spliced screen detects the flatness of splicing of the two screens by utilizing the signal difference received by the optical signal receiving tubes of the corresponding touch frames on the two screens, can accurately judge the flatness of the two screens without an experienced installer, saves labor cost and improves the flatness of mounting the spliced screen.
