At present, the infrared touch large screen is widely applied to scenes such as education, meetings, exhibition and the like. Usually, a plurality of infrared touch integrated machines are hung on a wall side by side to form an infrared touch large screen, and the infrared touch large screen is used for public information query, advertisement display, media interaction, conference content display and the like. Fig. 1 is a schematic structural diagram of an infrared touch all-in-one machine. As shown in fig. 1, a first infrared transmitting light bar in the Y direction, a first infrared receiving light bar in the Y direction, a second infrared transmitting light bar in the X direction, and a second infrared receiving light bar in the X direction are disposed around the screen of the infrared touch all-in-one machine. The transmitting light bar in each direction comprises a plurality of light tubes, and the receiving light bar in each direction comprises a plurality of infrared receiving light tubes. The microprocessor controls the driving circuit to sequentially switch on all the lamp tubes of the first infrared transmitting lamp strip from right to left and then sequentially switch on all the lamp tubes of the second infrared transmitting lamp strip from bottom to top, and the first infrared receiving lamp strip and the second infrared receiving lamp strip respectively receive infrared signals sent by all the lamp tubes to form an infrared light array which is crossed horizontally and vertically. When a user touches the screen, fingers can block two horizontal and vertical infrared type electronic whiteboard lines in the infrared light array passing through the position, so that the position of a touch point on the screen can be judged, and positioning information can be obtained.
However, if the large infrared touch screen comprises two infrared touch all-in-one machines which are horizontally arranged side by side, the problem of mutual interference of transmitted and received infrared rays exists in the horizontal direction of the two infrared touch all-in-one machines. Fig. 2 is a schematic structural diagram of a mid-infrared touch large screen in the prior art. As shown in fig. 2, the large infrared touch screen includes a first infrared touch all-in-one machine 201 and a second infrared touch all-in-one machine 202, wherein the first infrared touch all-in-one machine 201 and the second infrared touch all-in-one machine 202 are horizontally arranged side by side, and there is a problem that infrared rays emitted and received by the first infrared touch all-in-one machine 201 and the second infrared touch all-in-one machine 202 interfere with each other in the X direction, that is, the second infrared receiving light bar of the first infrared touch all-in-one machine 201 may receive an infrared signal emitted by a light tube of the first infrared receiving light bar of the second infrared touch all-in-one machine 202, so that touch sensitivity of the two infrared touch all-in-one. Therefore, in the prior art, by controlling two infrared touch all-in-one machines placed side by side, infrared rays are alternately emitted and received back and forth in the horizontal direction and the vertical direction, that is, when a first infrared emitting lamp strip and a first infrared receiving lamp strip of a first infrared touch all-in-one machine 201 emit and receive infrared signals, a second infrared emitting lamp strip and a second infrared receiving lamp strip of a second infrared touch all-in-one machine 202 emit and receive infrared signals, so that the two infrared touch all-in-one machines are prevented from simultaneously emitting and receiving infrared rays in the same direction at the same time, and mutual interference of the infrared rays is avoided.
However, in the prior art, only mutual interference of two infrared touch all-in-one machines can be avoided, and interference of transmitting and receiving infrared rays between more than two infrared touch all-in-one machines cannot be solved, so that a large infrared touch screen formed by a plurality of infrared touch all-in-one machines side by side is prone to faults such as insensitive touch or blockage.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 4 is a first flowchart of a method for controlling an infrared touch large screen according to an embodiment of the present invention. The execution subject of the present embodiment may be the control apparatus shown in fig. 3. As shown in fig. 4, the method includes:
s401, monitoring received effective signals in real time, wherein the effective signals are generated when each infrared touch all-in-one machine sends a first starting signal to an infrared emission lamp tube in a preset interference direction.
In the embodiment of the invention, when each infrared touch all-in-one machine sends the first starting signal to the infrared emission lamp tube in the preset interference direction, effective signals are generated and sent to N infrared touch all-in-one machines in the infrared touch large screen of the control equipment. Specifically, the first start signal is used for indicating that the infrared emission lamp tube in the preset interference direction is ready to be started, and the first start signal finally starts and closes the infrared emission lamp tube of each infrared touch integrated machine according to the time sequence signal sent by the control device without starting the infrared emission lamp tube in the preset interference direction. Illustratively, N infrared touch integrated machines in the infrared touch large screen send a first start signal to an infrared emission lamp tube in a preset interference direction, that is, N infrared touch integrated machines send N effective signals to the control device. The control device can obtain N effective signals by monitoring the received effective signals in real time.
In one possible implementation manner, if a plurality of infrared touch all-in-one machines in the infrared touch large screen are vertically arranged side by side, the preset interference direction is a vertical direction; if a plurality of infrared touch all-in-one machines in the infrared touch large screen are horizontally arranged side by side, the preset interference direction is the horizontal direction.
In the embodiment of the invention, when the plurality of infrared touch all-in-one machines in the infrared touch large screen are vertically arranged side by side, in order to avoid interference of infrared rays in the vertical direction sent by the plurality of infrared touch all-in-one machines, the vertical direction is set as the preset interference direction. When any infrared touch all-in-one machine sends a first starting signal to the infrared emission lamp tube to indicate the infrared emission lamp tube to be ready to emit and receive infrared rays in the vertical direction, the infrared touch all-in-one machine generates and sends an effective signal to the control equipment. Or when a plurality of infrared touch all-in-one machines in the infrared touch large screen are horizontally arranged side by side, in order to avoid the interference of infrared rays in the horizontal direction sent by the plurality of infrared touch all-in-one machines, the horizontal direction is set as a preset interference direction. When any infrared touch all-in-one machine sends a first starting signal to the infrared emission lamp tube to indicate the infrared emission lamp tube to be ready for emitting and receiving infrared rays in the horizontal direction, the infrared touch all-in-one machine generates and sends an effective signal to the control equipment.
S402, if N effective signals are received at any time, generating a first time sequence signal to an Nth time sequence signal according to the N effective signals, wherein N is an integer greater than or equal to 2.
In the embodiment of the invention, at any moment, when N infrared touch all-in-one machines in an infrared touch large screen send first starting signals to infrared emission lamp tubes in a preset interference direction, N infrared touch all-in-one machines send N effective signals to control equipment, and the control equipment receives the N effective signals and generates a first time sequence signal to an Nth time sequence signal according to the N effective signals. Illustratively, the signal period of each of the first to nth timing signals is N pulse intervals. The nth pulse interval of the nth timing signal in each signal period is an active level signal, and the rest N-1 pulse intervals are inactive level signals, wherein N is [1, N ]. Specifically, fig. 5 is a schematic diagram illustrating a first timing signal to a third timing signal according to an embodiment of the present invention. When 3 infrared touch integrated machines in the infrared touch large screen send a first starting signal to an infrared emission lamp tube in a preset interference direction, 3 infrared touch integrated machines send 3 effective signals to the control device, and the control device receives the 3 effective signals and generates a first time sequence signal to a third time sequence signal according to the 3 effective signals. As shown in fig. 5, the time interval of the pulse interval is set to T, and the active level signal is a high level signal and the inactive level signal is a low level signal. The signal period of each of the first to 3 rd timing signals is 3T, the 2 nd timing signal is a high level signal in the 2 nd T in each signal period, and the remaining 2T are low level signals.
And S403, respectively sending the first time sequence signal to the Nth time sequence signal to N infrared touch all-in-one machines corresponding to the N effective signals, so that each infrared touch all-in-one machine in the N infrared touch all-in-one machines controls the opening of an infrared emission lamp tube in a preset interference direction according to the received time sequence signal, wherein the first time sequence signal to the Nth time sequence signal are used for sequentially opening the infrared emission lamp tubes in the preset interference direction of the N infrared touch all-in-one machines, and only one infrared emission lamp tube in the preset interference direction of the N infrared touch all-in-one machines is opened at the same corresponding position at any moment.
In the embodiment of the invention, the control equipment respectively sends the first time sequence signal to the Nth time sequence signal to N infrared touch integrated machines corresponding to N effective signals. Specifically, the control device randomly sends the first time sequence signal to the Nth time sequence signal to the N infrared touch all-in-one machines, the corresponding relation between the first time sequence signal to the Nth time sequence signal and the N infrared touch all-in-one machines is not limited, and each infrared touch all-in-one machine receives one time sequence signal. And each infrared touch all-in-one machine of the N infrared touch all-in-one machines controls the opening of the infrared emission lamp tube in the preset interference direction according to the received time sequence signal. If the received time sequence signal is the nth time sequence signal, the opening of the infrared emission lamp tube in the preset interference direction is controlled in the nth pulse interval in each signal period, and the closing of the infrared emission lamp tube in the preset interference direction is controlled in the rest N-1 pulse intervals. For example, on the basis of the first to third timing signals provided in fig. 5, if the timing signal received by any of the 3 infrared touch all-in-one machines is the 2 nd timing signal, the infrared emission lamp in the preset interference direction is controlled to be turned on in the 2 nd pulse interval in each signal cycle, and the infrared emission lamp in the preset interference direction is controlled to be turned off in the remaining 2 pulse intervals. Therefore, the 3 infrared touch all-in-one machines are controlled to sequentially open the infrared emission lamp tubes in the preset interference direction, so that only one infrared emission lamp tube in the preset interference direction is opened at the same corresponding position of the 3 infrared touch all-in-one machines at any moment.
The method for controlling the large infrared touch screen provided by this embodiment includes controlling each of the infrared touch all-in-one machines to generate and send an effective signal to the control device when sending a first start signal to the infrared emission lamp tube in a preset interference direction, generating a first time sequence signal to an nth time sequence signal by the control device according to the N effective signals, and sending the first time sequence signal to the nth time sequence signal to the N infrared touch all-in-one machines corresponding to the N effective signals, respectively, so that each of the N infrared touch all-in-one machines opens the infrared emission lamp tube in the preset interference direction according to the respective time sequence signal, and at any time, at the same corresponding position, only one infrared emission lamp tube is opened by the N infrared touch all-in-one machines in the preset interference direction, thereby preventing a plurality of infrared touch all-in-one machine from emitting infrared rays in the same direction at the same corresponding position at the same time, the problem of mutual interference when a plurality of infrared touch integrated machines operate is solved, and the reliability of the operation of the infrared touch large screen is improved.

In the embodiment of the invention, when any one of the N infrared touch all-in-one machines sends the second starting signal to the infrared emission lamp tube in the non-preset interference direction, an invalid signal is generated and sent to the control equipment. The second starting signal is used for starting the infrared emission lamp tube in the non-preset interference direction. For example, if M is 1, S is a difference 2 between N and M, that is, the control device receives 1 invalid signal at any time, and the control device generates the first to second timing signals according to 1 invalid signal and 3 valid signals.
And S602, respectively sending the first time sequence signal to the S time sequence signal to S infrared touch integrated machines corresponding to the S effective signals.
