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 side and a second side, and the first side and the second side are respectively provided with a signal transmitting tube 1 and a signal receiving tube 2 which are corresponding to each other.
In this embodiment, the lengths of two opposite sides where the first screen 3 and the second screen 4 are spliced are equal, and the side where the splicing is defined as the spliced side. A plurality of signal transmitting tubes 1 are arranged on the touch frame vertical to one side of the splicing edge, and a plurality of signal receiving tubes 2 are arranged on the touch frame vertical to the other side of the splicing edge. Each signal receiving pipe 1 is provided with a signal receiving pipe 2 which is opposite to each other. The touch frame adopts an adhesive tape design, and a plurality of holes are formed in the touch frame, and each hole is used for fixing one or more signal transmitting pipes/signal receiving pipes.
Referring to fig. 1, in an embodiment of the present application, a method for detecting flatness of a spliced screen is provided, where a signal transmitting tube disposed on a touch frame and adjacent to a first screen 3 is a first transmitting tube, a signal receiving tube disposed on the touch frame and adjacent to the first screen 3 is a first receiving tube, and a signal receiving tube disposed on the touch frame and adjacent to a second screen 4 is a second receiving tube, and the method for detecting flatness of a spliced screen includes:
s1, controlling the first transmitting tube to transmit 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, the first receiving tube and the second receiving tube can both receive the optical signals sent by the first sending 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 smoothly;
and S4, displaying specified information on the first screen 3 or the second screen 4, wherein the specified information is used for indicating that the spliced screen of the user is spliced smoothly.
In this embodiment, specifically, referring to fig. 4, the whole display screen is formed by combining two screens, which are a first screen 3 and a second screen 4, respectively, where 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 edges of the width of the first screen 3 and the second screen 4 are assembled together 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 pipes are arranged on the wide sides of the connection parts of the first screen 3 and the second screen 4, and in fig. 4, 1 points to the transmitting pipe and 2 points to the receiving pipe. Specifically, the touch frame is provided with a first receiving tube at a position close to the first screen 3 and close to the second screen 4, and the touch frame is provided with a second receiving tube at a position close to the second screen 4 and close to the first screen 3. Meanwhile, a first transmitting tube for transmitting optical signals is arranged on the corresponding broadside, close to the first screen 3, of the touch frame, and the first transmitting tube faces the first receiving tube; in addition, because the distance between the first receiving tube and the second receiving tube is very close, the optical signal emitted by the first emitting tube also has a certain scattering function, so that the optical signal emitted by the first emitting tube can be mostly 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 this time, a first transmitting tube on the first screen 3 sends out an 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 intensity of the received optical signal, and since the first receiving tube and the first transmitting tube are both positioned on the first screen 3, the whole screen is flat, and therefore the intensity of the optical signal received by the first receiving tube is fixed; meanwhile, a 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 determines the flatness of the installation of the first screen 3 and the second screen 4 based on the difference between the two signal values. If the difference value is smaller, the normal deviation range of the light signal received by the second receiving tube indicates that the screens of the first screen 3 and the second screen 4 are positioned on the same plane, and the total screen is spliced smoothly; if the difference is larger, the deviation of the light signals received by the second receiving tube is larger, which means that the screens of the first screen 3 and the second screen 4 are not in the same horizontal plane, and adjustment is needed.
It should be noted that, as long as the first screen 3 and the second screen 4 are uneven, since the first transmitting tube is only installed at the position close to the first screen 3, the first receiving tube is installed at the position close to the first screen 3, and the second receiving tube is installed at the position close to the second screen 4, under the condition that the first screen 3 is even, the first receiving tube is always opposite to the first transmitting tube, and the corresponding first signal value is always greater than the second signal value.
The light signal emitted by the first emitting tube received by the second receiving tube is weak, possibly because the first screen 3 is higher than the second screen 4, so that the first emitting tube is higher than the second receiving tube, and thus the upper end part of the second receiving tube can only receive the light signal, so that the light signal received by the second receiving tube is weak, and the generated second signal value is smaller; of course, there is another case that if the first screen 3 is lower than the second screen 4, the signal emitted by the first transmitting tube is partially blocked by the edge of the second screen 4 when it faces the second receiving tube, which also results in weaker optical signals received by the second receiving tube and smaller values of the generated second signal. Therefore, according to the magnitudes of the first signal value and the second signal value, it can be judged whether or not the first screen 3 and the second screen 4 are spliced flat. In another specific embodiment, a second transmitting tube is arranged at a position, close to the second screen 4, opposite to the second receiving tube, on the touch frame, and when whether the first transmitting tube emits light signals is detected to be flat or not, after the first transmitting tube emits light signals, the second transmitting tube is controlled to emit light signals, 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 flat or not is judged according to the third signal value and the fourth signal value, and the judging method can also be used for calculating the difference value of the third signal value and the fourth signal value to be within a certain range and judging that the first screen 3 and the second screen 4 are flat or not. In addition, the two steps can be performed sequentially, and when the two signal values meet the preset rule as a result of the two steps, the first screen 3 and the second screen 4 are judged to be spliced smoothly. And then displaying the successfully installed typeface on the first screen 3 or the second screen 3 so that the user can know that the splicing is smooth.
The first transmitting tube and the second transmitting tube respectively refer to a signal transmitting tube, and the first receiving tube and the second receiving tube respectively refer to 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 corresponding number of the first receiving tubes is also N signal transmitting tubes. When in detection, each signal transmitting tube of the first transmitting tube is controlled to sequentially transmit optical signals, the signal receiving tube of each corresponding first receiving tube and the signal receiving tube of the second receiving tube both receive N optical signals, then the first receiving tube obtains N optical signals, and the second receiving tube also obtains N optical signals. And then respectively calculating the optical signals to obtain a corresponding first signal value and a corresponding second signal value. In a specific embodiment, the calculation process of the first signal value is: respectively reading the optical signals received by each first receiving tube, deleting the optical signals with the signal strength lower than a specified first strength threshold value, and calculating the average value of the rest optical signals to obtain a first signal value; the calculation process of the second signal value is as follows: and respectively reading the optical signals received by each second receiving tube, deleting the optical signals with the signal strength lower than the designated second strength threshold value, and calculating the average value of the rest optical signals to obtain a second signal value. Errors caused by damage to 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 spliced and leveled 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 or not;
and S33, if so, judging that the first screen 3 and the second screen 4 are spliced and leveled.
In this embodiment, the processor reads the first signal value and the second signal value simultaneously, and calculates the difference between the first signal value and the second signal value, and because the first receiving tube is certainly located at the same horizontal plane as the first transmitting tube and the first receiving tube is opposite to the first transmitting tube, the signal intensity received by the first receiving tube is certainly higher than the signal intensity received by the second receiving tube, 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. And then calling a preset signal threshold, wherein the signal threshold is a standard threshold for judging whether the total screen is flat or not. If the signal difference value is smaller than the preset signal threshold value, which indicates that the signal intensity received by the first receiving tube and the second receiving tube is 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 first screen 3 are also on the same horizontal plane, the first screen 3 and the second screen 4 are judged to be spliced smoothly.
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;
s302, multiplying the screen width value by a preset threshold coefficient to obtain the signal threshold.
In this embodiment, if the width value of the screen is larger, 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 passing a longer distance, the influence of the first receiving tube on the intensity of the received signal which can be brought by the first transmitting tube is lower due to the divergence of the optical signal; that is, if the first screen and the second screen are flat and located on the same horizontal plane, the farther the first transmitting tube and the first receiving tube are away, the more closely the signal intensities received by the first receiving tube and the second receiving tube will be. The distance between the first transmitting tube and the first receiving tube is the width of the screen. Therefore, it is necessary to correlate with the width of the screen when setting the signal threshold. Specifically, before executing the above step S33, a screen width value of the screen width is first obtained, 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 value can be acquired more accurately, and whether the installation of the first screen 3 and the second screen 4 which are correspondingly judged is smooth or not is more accurate.
In one embodiment, the step of obtaining the screen width value includes:
s311, the attribute information of the first screen 3 is read, and the screen width value is called.
In the present embodiment, since the widths of the first screen 3 and the second screen 4 are the same, the widths of the total screens formed by the corresponding combinations are also the same, and the widths of the screens are the inherent attribute information of the screens. Therefore, in this solution, the attribute information of the first screen 3 may 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 of 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 when the first transmitting tube transmits the optical signal and the time when the first receiving tube receives the optical signal.
In this embodiment, the first emitting tube and the first receiving tube are respectively located on two wide sides of the first screen 3 and face each other, so that the distance between the first receiving tube and the first emitting 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 ranging 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 transmitting the optical signal and the time of the first receiving tube receiving the optical signal, so that the screen width value is obtained. The calculating process comprises the steps of controlling a first transmitting tube to transmit light signals, recording the time for transmitting the light signals as first time, obtaining the time for receiving the light signals by a first receiving tube, recording the time as second time, subtracting the first time from the second time to obtain a time difference, and multiplying the time difference by the speed of light signal transmission to obtain a screen width value. In one embodiment, the first time is recorded when the step S1 is performed, and the second time is recorded when the step S2 is performed. Only once light signal is needed to be emitted, then when judging, the signal difference value and the signal threshold value are calculated according to the first time and the second time, and then whether the first screen 3 and the second screen 4 are spliced and leveled is judged, so that the utilization efficiency of the first emitting tube can be improved.
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 comprises:
and S4, if the first signal value and the second signal value do not accord with a preset rule, judging that the first screen 3 and the second screen 4 are not spliced smoothly, controlling the first emitting 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 spliced flat, adjustment is required 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. During the adjustment, it is difficult for the operator to quickly find out whether 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 this scheme, show first signal value and second signal value on first screen 3 and/or second screen 4, make the staff can see two signal values in real time when adjusting, because first signal value is fixed, the second signal value can change because the roughness of first screen and second screen 4, and the more level of two screens, the difference between second signal value and the first signal value can be less. When the operator adjusts the second screen 4, the operator may perform closed-loop adjustment 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 fine-tuned downwards, the difference between the first signal value and the second signal value becomes larger, this means that the operator needs to fine-tune upwards. By displaying the two signal values on the first screen 3 and/or the second screen 4, a directional, more rapid adjustment of the flatness of the first screen and the second screen 4 by the staff is facilitated.
In one embodiment, the spliced screen at least comprises a first screen 3 and a second screen 4, the spliced screen comprises two broadsides and two long sides, the first transmitting tube, the first receiving tube and the second receiving tube are positioned on touch frames corresponding to the broadsides, and a fifth transmitting tube and a fifth receiving tube are respectively arranged on the touch frames corresponding to the two long sides; if the first signal value and the second signal value meet a preset rule, the step of determining that the first screen 3 and the second screen 4 are spliced and leveled includes:
s34, controlling the fifth transmitting tube to transmit light signals, wherein the direction of the light signals transmitted by the fifth transmitting tube is perpendicular to the direction of the light signals transmitted 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 6, the spliced screen is composed of the first screen 3 and the second screen 4, however, the third screen may be added, and the like, without any excessive limitation. The width of the multiple screens (such as N screens) is equal, and the long sides of the multiple screens are assembled in sequence to form a spliced screen. The spliced screen has the same meaning as the above-described total screen. The broadsides of the multiple screens sequentially extend to form the broadsides of the spliced screen, and the first screen and the last screen (the first screen 3 and the N screen) are long sides of the spliced screen. After detecting that the first signal value and the second signal value conform to a preset rule through a first transmitting tube arranged on the wide side of the first screen 3, judging that the first screen 3 and the second screen 4 are spliced and leveled, continuously judging that the second screen 4 and the third screen are spliced and leveled, and after verifying that every two adjacent screens are spliced and leveled from a transmitting tube and a receiving tube arranged on the wide side in sequence, further performing more accurate detection and verification.
