Description

Technical Field

[0001] The present application relates to the technical field of power-assisted inspection devices, and in particular to an infrared radiation detection device. Background Art

[0002] At present, the gate machines on the market usually use infrared transmitters and infrared receivers to detect the traffic status in the gate machine channel. The more infrared transmitters and infrared receivers there are, the higher the sensitivity of the detection in the gate machine channel. Usually, the infrared rays emitted by the infrared transmitter diverge outward in a cone shape. Therefore, the closer the distance between the infrared transmitter and the infrared receiver, the smaller the coverage range of the infrared rays emitted by the infrared transmitter. If the coverage range of the infrared rays emitted by the infrared transmitter is too small, the probability of the infrared rays emitted by the infrared transmitter and the infrared receiver being aligned will be greatly reduced, and even the corresponding infrared receiver will not be able to receive the infrared rays. In order to improve the alignment accuracy of the infrared transmitter and the infrared receiver and reduce the failure probability of the gate machine, the existing technical solutions usually use gears, racks or worm gears to adjust the distance and position between the infrared transmitter and the infrared receiver so that the infrared transmitter is aligned with the infrared receiver.

[0003] It should be noted that the greater the distance between the infrared transmitter and the infrared receiver, the greater the coverage range of the infrared light emitted by the infrared transmitter. Therefore, excessive infrared coverage will interfere with the logical judgment of the adjacent infrared receiver. In other words, although the existing technical solutions can ensure that the infrared transmitter is aimed at the infrared receiver, it cannot ensure that the infrared light emitted by the infrared transmitter will not interfere with the judgment of the adjacent infrared receiver. Summary of the invention

[0004] Based on this, it is necessary to provide an infrared radiation detection device so that the infrared light emitted by the infrared transmitter can be received by the corresponding infrared receiver without interfering with the adjacent infrared receivers.

[0005] The infrared cross-beam detection device provided by the present application includes a first mounting portion, a second mounting portion and an indication component. The first mounting portion is used to mount an infrared transmitter to be tested or an infrared receiver to be tested. The second mounting portion is spaced apart from the first mounting portion, and the second mounting portion is provided with a preset center point, at least one group of first assembly positions and at least one group of second assembly positions, and the first assembly position and the second assembly position are respectively used to mount an infrared transmitter or an infrared receiver; a group of first assembly positions and a corresponding group of second assembly positions constitute a detection unit, and in the same detection unit, the distance d between the first assembly position and the preset center point is less than the distance D between the second assembly position and the preset center point. The indication component is electrically connected to the infrared transmitter or infrared receiver provided in the second mounting portion to indicate whether the infrared transmitter or infrared receiver provided in the second mounting portion is connected to the infrared transmitter to be tested or the infrared receiver to be tested.

[0006] In one embodiment, the infrared beam detection device further comprises a slide rail portion, the first mounting portion and / or the second mounting portion are mounted on the slide rail portion, and the first mounting portion and / or the second mounting portion are movably arranged along the length direction of the slide rail portion. It can be understood that such an arrangement is conducive to testing the coverage range of the infrared transmitter to be tested or the receiving range of the infrared receiver at different distances.

[0007] In one embodiment, the slide rail portion is provided with scales distributed along the length direction. It can be understood that such a configuration is conducive to accurately controlling the distance between the first mounting portion and the second mounting portion.

[0008] In one embodiment, the first mounting portion is provided with a first placement groove, and the first placement groove is used for detachably mounting the infrared transmitter or the infrared receiver to be tested. It can be understood that such a configuration is conducive to improving the installation efficiency of the infrared transmitter or the infrared receiver to be tested in the first mounting portion.

[0009] In one embodiment, a mounting opening is provided on one side of the first mounting groove, and the infrared transmitter to be tested or the infrared receiver to be tested is mounted in the first mounting groove through the mounting opening, and a movable clamp is provided at the mounting opening to open or close the mounting opening. It can be understood that such a setting is conducive to facilitating the disassembly and assembly of the infrared transmitter to be tested and the infrared receiver to be tested.

[0010] In one embodiment, one end of the movable clamp is hinged to the first mounting portion, and the other end is magnetically connected to the first mounting portion. It is understandable that such a configuration is conducive to facilitating the opening and closing of the assembly port of the movable clamp.

[0011] In one embodiment, a gasket is provided on one side of the movable card plate close to the first placement groove, and the movable card plate applies pressure to the infrared transmitter or the infrared receiver to be tested through the gasket. It can be understood that such a configuration is conducive to improving the installation firmness of the infrared transmitter or the infrared receiver to be tested in the first placement groove.

[0012] In one embodiment, each group of first assembly positions is provided with a plurality of first installation positions, and the first installation positions are evenly spaced; and / or each group of second assembly positions is provided with a plurality of second installation positions, and the second installation positions are evenly spaced. It is understandable that such a setting is conducive to improving the limiting accuracy of the first assembly position and the second assembly position.

[0013] In one embodiment, each group of first assembly positions is provided with a plurality of first installation positions, the indicating assembly includes a plurality of first indicator lights, and the first installation positions correspond to the first indicator lights one by one; and / or each group of second assembly positions is provided with a plurality of second installation positions, the indicating assembly includes a plurality of second indicator lights, and the second installation positions correspond to the second indicator lights one by one. It is understandable that such a setting is conducive to more conveniently and quickly displaying whether the infrared transmitter and the infrared receiver are connected.

[0014] In one embodiment, the second mounting portion includes a mounting plate and a mounting base connected to the bottom of the mounting plate, and the preset center point, at least one set of first assembly positions and at least one set of second assembly positions are all arranged on the mounting plate.

[0015] Compared with the prior art, the infrared beam detection device provided by the present application, when testing the infrared transmitter, the infrared transmitter to be tested is installed on the first installation part, and the infrared transmitter emits infrared rays toward the second installation part, and the infrared receiver is respectively assembled at the first assembly position and the second assembly position of the second installation part. Since a group of first assembly positions and a corresponding group of second assembly positions constitute a detection unit, in the same detection unit, the distance d between the first assembly position and the preset center point is less than the distance D between the second assembly position and the preset center point. In addition, the infrared rays emitted by the infrared transmitter are usually cone-shaped, therefore, when the power supply of the indicating component is turned on, when the indicating component indicates that the infrared receiver on the first assembly position is successfully connected to the infrared transmitter and the indicating component indicates that the infrared receiver on the second assembly position is unsuccessful in connecting to the infrared transmitter, it indicates that the coverage range of the infrared rays emitted by the infrared transmitter to be tested is between the first assembly position and the second assembly position, so that it is conducive to ensuring that the infrared light emitted by the infrared transmitter can be received by the corresponding infrared receiver and will not interfere with the adjacent infrared receiver, and further indicates that the installation position of the infrared transmitter to be tested meets the requirements. Similarly, when testing the infrared receiver, the infrared receiver to be tested is installed on the first installation part, and the infrared transmitter is installed on the first assembly position and the second assembly position of the second installation part respectively, and the infrared transmitter emits infrared rays toward the first installation part. Since a group of first assembly positions and a corresponding group of second assembly positions constitute a detection unit, in the same detection unit, the distance d between the first assembly position and the preset center point is less than the distance D between the second assembly position and the preset center point. In addition, the infrared rays emitted by the infrared transmitter are usually cone-shaped, therefore, when the power of the indicating component is turned on, when the indicating component indicates that the infrared transmitter on the first assembly position is successfully connected to the infrared receiver and the indicating component indicates that the infrared transmitter on the second assembly position is unsuccessful in connecting to the infrared receiver, it indicates that the infrared rays emitted by the infrared transmitter arranged at the first assembly position can effectively cover the infrared receiver to be tested, and the infrared rays emitted by the infrared transmitter arranged at the second assembly position cannot effectively cover the infrared receiver to be tested. This helps ensure that the infrared receiver can effectively receive infrared rays emitted by the infrared transmitter located at the first assembly position and will not receive infrared rays emitted by the infrared transmitter located at the second assembly position. Further, it indicates that the installation position of the infrared receiver to be tested meets the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] At present, the gate machines on the market usually use infrared transmitters and infrared receivers to detect the traffic status in the gate machine channel. The more infrared transmitters and infrared receivers there are, the higher the sensitivity of the detection in the gate machine channel. Usually, the infrared rays emitted by the infrared transmitter diverge outward in a cone shape. Therefore, the closer the distance between the infrared transmitter and the infrared receiver, the smaller the coverage range of the infrared rays emitted by the infrared transmitter. If the coverage range of the infrared rays emitted by the infrared transmitter is too small, the probability of the infrared rays emitted by the infrared transmitter and the infrared receiver being aligned will be greatly reduced, and even the corresponding infrared receiver will not be able to receive the infrared rays. In order to improve the alignment accuracy of the infrared transmitter and the infrared receiver and reduce the failure probability of the gate machine, the existing technical solutions usually use gears, racks or worm gears to adjust the distance and position between the infrared transmitter and the infrared receiver so that the infrared transmitter is aligned with the infrared receiver.

[0031] It should be noted that the greater the distance between the infrared transmitter and the infrared receiver, the greater the coverage range of the infrared light emitted by the infrared transmitter. Therefore, excessive infrared coverage will interfere with the logical judgment of the adjacent infrared receiver. In other words, although the existing technical solutions can ensure that the infrared transmitter is aimed at the infrared receiver, it cannot ensure that the infrared light emitted by the infrared transmitter will not interfere with the judgment of the adjacent infrared receiver.

[0032] See also Figure 1-Figure 5, so that the infrared light emitted by the infrared transmitter 100 can be received by the corresponding infrared receiver 200 without interfering with the adjacent infrared receiver 200. The present application provides an infrared cross-beam detection device, which includes a first mounting portion 300, a second mounting portion 400 and an indicating component 500. The first mounting portion 300 is used to mount the infrared transmitter 100 or the infrared receiver 200 to be tested. The second mounting portion 400 is spaced apart from the first mounting portion 300, and the second mounting portion 400 is provided with a preset center point 410, a first assembly position 420 and a second assembly position 430, and the first assembly position 420 and the second assembly position 430 are respectively used to mount the infrared transmitter 100 or the infrared receiver 200. A group of first assembly positions 420 and a corresponding group of second assembly positions 430 constitute a detection unit, and in the same detection unit, the distance d between the first assembly position 420 and the preset center point 410 is less than the distance D between the second assembly position 430 and the preset center point 410. It can be known from mathematical laws that a plane figure with equal distance from a point is a circle. Therefore, it can be known that the first assembly position 420 is distributed on a circumference with a distance d from the preset center point 410, and the second assembly position 430 is distributed on a circumference with a distance D from the preset center point 410, and D>d. The indicating component 500 is used to electrically connect the infrared transmitter 100 or the infrared receiver 200 provided in the second mounting portion 400 to indicate whether the infrared transmitter 100 or the infrared receiver 200 provided in the second mounting portion 400 is connected to the infrared transmitter 100 or the infrared receiver 200 provided in the first mounting portion 300. It should be noted that the preset center point 410 is only a relative position concept, which is relative to the first assembly position 420 and the second assembly position 430. In this embodiment, the position of the preset center point 410 also reserves the installation position of the infrared transmitter 100 or the infrared receiver 200.

[0033] It should be noted that different groups of first assembly positions 420 and different groups of second assembly positions 430 can be arranged and combined to form different detection units. The number of first assembly positions 420 and second assembly positions 430 can be flexibly set according to the coverage of different types of infrared transmitters 100 or infrared receivers 200. For example, the first assembly positions 420 and second assembly positions 430 can also be set in multiple circles. On the basis of detecting whether the infrared transmitter 100 and the infrared receiver 200 are qualified, the signal strength of the same infrared transmitter 100 and infrared receiver 200 at different positions can be tested by setting multiple circles of the first assembly positions 420 and the second assembly positions 430 to verify the performance of the infrared cross-beam detection device.

[0034] When testing the infrared transmitter 100, the infrared transmitter 100 to be tested is installed on the first installation portion 300, and the infrared transmitter 100 emits infrared rays toward the second installation portion 400, and the infrared receiver 200 is respectively installed at the first assembly position 420 and the second assembly position 430 of the second installation portion 400. Since the first assembly position 420 is distributed on a circumference with a distance d from the preset center point 410, the second assembly position 430 is distributed on a circumference with a distance D from the preset center point 410, and D>d. Furthermore, the infrared rays emitted by the infrared transmitter 100 are usually in a cone shape. Therefore, when the power of the indicating component 500 is turned on, when the indicating component 500 indicates that the infrared receiver 200 on the first assembly position 420 is successfully connected to the infrared transmitter 100 and the indicating component 500 indicates that the infrared receiver 200 on the second assembly position 430 is unsuccessfully connected to the infrared transmitter 100, it indicates that the coverage range of the infrared rays emitted by the infrared transmitter 100 to be tested is between the first assembly position 420 and the second assembly position 430. This helps to ensure that the infrared light emitted by the infrared transmitter 100 can be received by the corresponding infrared receiver 200 and will not interfere with the adjacent infrared receiver 200. Further, it indicates that the installation position of the infrared transmitter 100 to be tested meets the requirements.

[0035] It should be noted that when the indicating component 500 indicates that the infrared receiver 200 on the first assembly position 420 fails to connect to the infrared transmitter 100, it means that the infrared light emitted by the infrared transmitter 100 cannot effectively cover the corresponding infrared receiver 200. At this time, it is necessary to further adjust the position of the infrared transmitter 100 so that the infrared light emitted by the infrared transmitter 100 effectively covers the corresponding infrared receiver 200. Similarly, when the indicating component 500 indicates that the infrared receiver 200 on the second assembly position 430 is successfully connected to the infrared transmitter 100, it means that the infrared light emitted by the infrared transmitter 100 has a large coverage range and may interfere with the judgment of the adjacent infrared receiver 200. At this time, it is necessary to further adjust the position of the infrared transmitter 100 so that the infrared light emitted by the infrared transmitter 100 does not cover the adjacent infrared receiver 200.

[0036] Similarly, when testing the infrared receiver 200, the infrared receiver 200 to be tested is installed on the first mounting portion 300, and infrared transmitters are respectively installed on the first assembly position 420 and the second assembly position 430 of the second mounting portion 400, and the infrared transmitter 100 emits infrared rays toward the first mounting portion 300. Since the first assembly position 420 is distributed on a circumference with a distance d from the preset center point 410, the second assembly position 430 is distributed on a circumference with a distance D from the preset center point 410, and D>d. Furthermore, the infrared rays emitted by the infrared transmitter 100 are usually in a cone shape. Therefore, when the power of the indicating component 500 is turned on, when the indicating component 500 indicates that the infrared transmitter 100 on the first assembly position 420 is successfully connected to the infrared receiver 200 and the indicating component 500 indicates that the infrared transmitter 100 on the second assembly position 430 is unsuccessfully connected to the infrared receiver 200, it indicates that the infrared rays emitted by the infrared transmitter 100 located at the first assembly position 420 can effectively cover the infrared receiver 200 to be tested, and the infrared rays emitted by the infrared transmitter 100 located at the second assembly position 430 cannot effectively cover the infrared receiver 200 to be tested. In this way, it is helpful to ensure that the infrared receiver 200 can effectively receive the infrared rays emitted by the infrared transmitter 100 located at the first assembly position 420, and will not receive the infrared rays emitted by the infrared transmitter 100 located at the second assembly position 430, and further indicates that the installation position of the infrared receiver 200 to be tested meets the requirements.

[0037] It should be noted that when the indicating component 500 indicates that the infrared transmitter 100 on the first assembly position 420 fails to connect with the infrared receiver 200, it means that the infrared receiver 200 cannot receive the infrared light emitted by the infrared transmitter 100 located on the first assembly position 420. At this time, it is necessary to further adjust the position of the infrared receiver 200 so that the infrared receiver 200 is located within the coverage range of the corresponding infrared light. Similarly, when the indicating component 500 indicates that the infrared transmitter 100 on the second assembly position 430 is successfully connected with the infrared receiver 200, it means that the infrared light coverage range emitted by the infrared transmitter 100 located at the second assembly position 430 is too large, which interferes with the judgment of the adjacent infrared receiver 200. At this time, it is necessary to further adjust the position of the infrared receiver 200 so that the infrared receiver 200 is not located within the coverage range of the adjacent infrared light.

[0038] In order to improve the limiting accuracy of the first assembly position 420, in one embodiment, as Figure 2As shown, each group of first assembly positions 420 is provided with a plurality of first installation positions 421, and the first installation positions 421 are evenly spaced. Since the first assembly positions 420 are distributed on a circumference with a distance d from the preset center point 410, a plurality of first installation positions 421 are evenly distributed on the circumference. In this way, when the infrared receiver 200 in any first assembly position 420 can establish a connection with the infrared ray emitted by the infrared transmitter 100 to be tested, it can be determined that the infrared ray emitted by the infrared transmitter 100 to be tested perfectly covers the corresponding infrared receiver 200. Similarly, when the infrared ray emitted by the infrared transmitter 100 in any first assembly position 420 can establish a connection with the infrared receiver 200 to be tested, it can be determined that the infrared receiver 200 to be tested can be perfectly aligned with the corresponding infrared transmitter 100. It should be noted that when the infrared cross-beam detection device is powered on, the infrared transmitter 100 in the first installation position 421 sequentially faces the infrared ray emitted by the infrared receiver 200 to be tested. The more the number of the first installation positions 421 is, the higher the detection accuracy of the infrared radiation detection device is. In this embodiment, the number of the first installation positions 421 is set to 4, but is not limited thereto. In other embodiments, the number of the first installation positions 421 can also be 3, 5 or 6, which are not listed here one by one.

[0039] Similarly, in order to improve the limiting accuracy of the second assembly position 430, in one embodiment, as Figure 2 As shown, each group of second assembly positions 430 is provided with a plurality of second installation positions 431, and the second installation positions 431 are evenly spaced. Since the second assembly positions 430 are distributed on a circumference with a distance D from the preset center point 410, a plurality of second installation positions 431 are evenly distributed on the circumference. In this way, when the infrared receiver 200 in any second installation position 431 cannot establish a connection with the infrared ray emitted by the infrared transmitter 100 to be tested, it can be determined that the infrared ray emitted by the infrared transmitter 100 to be tested will not interfere with the adjacent infrared receiver 200. Similarly, when the infrared ray emitted by the infrared transmitter 100 in any second installation position 431 cannot establish a connection with the infrared receiver 200 to be tested, it can be determined that the infrared receiver 200 to be tested can avoid interference from the adjacent infrared transmitter 100. It should be noted that when the infrared cross-beam detection device is powered on, the infrared transmitters 100 in the second installation position 431 sequentially face the infrared ray emitted by the infrared receiver 200 to be tested. The more the number of the second installation positions 431 is, the higher the detection accuracy of the infrared radiation detection device is. In this embodiment, the number of the second installation positions 431 is set to 4, but is not limited thereto. In other embodiments, the number of the second installation positions 431 can also be 3, 5 or 6, which are not listed here one by one.

[0040] In order to more conveniently and quickly display whether the infrared transmitter 100 and the infrared receiver 200 are connected, in one embodiment, as Figure 2 As shown, each group of first assembly positions 420 is provided with a plurality of first installation positions 421, and the indicating assembly 500 includes a plurality of first indicator lights 510, and the first installation positions 421 correspond to the first indicator lights 510 one by one. Similarly, in another embodiment, each group of second assembly positions 430 is provided with a plurality of second installation positions 431, and the indicating assembly 500 includes a plurality of second indicator lights 520, and the second installation positions 431 correspond to the second indicator lights 520 one by one. The first indicator lights 510 and the second indicator lights 520 can be distinguished by turning on and off or displaying different colors or flashing to distinguish whether the infrared transmitter 100 and the infrared receiver 200 are connected. For example, when the infrared transmitter 100 and the infrared receiver 200 are connected, the first indicator light 510 or the second indicator light 520 displays green, and when the infrared transmitter 100 and the infrared receiver 200 are not connected, the first indicator light 510 or the second indicator light 520 displays red.

[0041] In order to stably arrange the second mounting portion 400, in one embodiment, as Figure 2 As shown, the second mounting portion 400 includes a mounting plate 440 and a mounting base 450 connected to the bottom of the mounting plate 440, and a preset center point 410, at least one group of first assembly positions 420 and at least one group of second assembly positions 430 are provided on the mounting plate 440. Further, a connecting plate 700 is provided at the bottom of the first mounting portion 300 and the second mounting portion 400, and the mounting base 450 is detachably connected to the connecting plate 700 by fasteners.

[0042] In order to improve the installation efficiency of the infrared transmitter 100 or the infrared receiver 200 to be tested in the first installation portion 300, in one embodiment, as Figure 3 As shown, the first mounting portion 300 is provided with a first placement groove 310, and the first placement groove 310 is used for detachably mounting the infrared transmitter 100 or the infrared receiver 200 to be tested. That is, the infrared transmitter 100 or the infrared receiver 200 to be tested can be clamped in the first placement groove 310, or the infrared transmitter 100 or the infrared receiver 200 to be tested can be threadedly connected to the first mounting portion 300 through a fastener, but it is not limited thereto, and the infrared transmitter 100 or the infrared receiver 200 to be tested can also be detachably arranged in the first placement groove 310 in other ways, which are not listed here one by one.

[0043] Furthermore, in order to facilitate the disassembly and assembly of the infrared transmitter 100 to be tested and the infrared receiver 200 to be tested, in one embodiment, as Figure 3As shown, a mounting opening 320 is provided on one side of the first placement groove 310, and the infrared transmitter 100 or the infrared receiver 200 is mounted in the first placement groove 310 through the mounting opening 320. A movable clamping plate 330 is provided at the mounting opening 320 to open or close the mounting opening 320. Further, in order to facilitate the opening and closing of the mounting opening 320 of the movable clamping plate 330, in one embodiment, one end of the movable clamping plate 330 is hinged to the first mounting part 300, and the other end is magnetically connected to the first mounting part 300. Specifically, the movable clamping plate 330 and the first mounting part 300 are respectively provided with magnets 360 with different magnetic poles. When the infrared transmitter 100 or the infrared receiver 200 to be tested is set in the first placement groove 310, the movable clamping plate 330 and the first mounting part 300 are firmly adsorbed together. When it is necessary to take out the infrared transmitter 100 or the infrared receiver 200 to be tested, it is only necessary to separate the movable clamping plate 330 and the first mounting part 300 by external force. However, the invention is not limited thereto, and the movable clamping plate 330 may also be clamped or threadedly connected to the first mounting portion 300 .

[0044] In order to improve the installation firmness of the infrared transmitter 100 or the infrared receiver 200 to be tested in the first installation groove 310, in one embodiment, as Figure 3 As shown, a gasket 340 is provided on one side of the movable card plate 330 close to the first placement groove 310, and the movable card plate 330 applies pressure toward the infrared transmitter 100 or the infrared receiver 200 through the gasket 340. In this way, the movable card plate 330 increases the maximum static friction between the infrared transmitter 100 or the infrared receiver 200 to be tested and the inner wall of the first placement groove 310 through the gasket 340, preventing the infrared transmitter 100 or the infrared receiver 200 to be tested from falling off from the first placement groove 310. Further, the gasket 340 can be made of a flexible material such as foam, so that a buffer can be established between the movable card plate 330 and the infrared transmitter 100 or the infrared receiver 200 to be tested, preventing the movable card plate 330 from damaging the infrared transmitter 100 or the infrared receiver 200 to be tested.

[0045] In order to test the coverage range of the infrared transmitter 100 or the receiving range of the infrared receiver 200 at different distances, in one embodiment, as Figure 1 and Figure 6As shown, the infrared counter-radiation detection device also includes a slide rail portion 600, and the first mounting portion 300 and / or the second mounting portion 400 are mounted on the slide rail portion 600, and the first mounting portion 300 and / or the second mounting portion 400 are movably arranged along the length direction of the slide rail portion 600. In this way, the distance between the first mounting portion 300 and the second mounting portion 400 can be adjusted by the slide rail portion 600 to achieve the coverage range of the infrared transmitter 100 to be tested or the receiving range of the infrared receiver 200 at different distances. In this embodiment, the first mounting portion 300 can be slidably mounted on the slide rail portion 600, and the second mounting portion 400 is fixedly arranged. Specifically, a card slot 350 is provided at the bottom of the first mounting portion 300, and the card slot 350 can be slidably engaged with the slide rail portion 600. Further, in order to accurately control the distance between the first mounting portion 300 and the second mounting portion 400, in one of the embodiments, as Figure 6 As shown, the slide rail portion 600 is provided with scales 610 distributed along the length direction.
