[0055] The current means for testing the infrared counter-radiation characteristic parameters include: first, installing the infrared counter-radiation on a channel blocking device such as a gate, and then testing the characteristic parameters of the infrared counter-radiation with the help of a test tool. However, because the position of the gate is relatively fixed, there is a large error between the characteristic parameters of the infrared counter-radiation obtained by the test and the actual characteristic parameters. In order to reduce the test error of the characteristic parameters of the infrared counter-radiation and improve the test accuracy, the utility model provides a test tool. Figures 1 to 4 The test tooling of the utility model is described in detail. Figure 1 It is a structural schematic diagram of the test tooling provided by the utility model; Figure 2 It is a partial structural schematic diagram of the fixing parts of the test tool provided by the utility model; Figure 3 It is a structural schematic diagram of using the test tool provided by the utility model to test the first half angle θ1 of the first pointing angle of infrared radiation; Figure 4 The utility model is a schematic diagram of a structure for testing the parallel maximum non-interference distance of infrared counter-radiation by using the testing tool provided by the utility model.

[0056] It should be noted that in the specific embodiments of the present invention, for the convenience of description, the two fixed platforms of the first measuring mechanism 100 are respectively named as the first fixed platform 110 and the second fixed platform 120. The fixed platform of the second measuring mechanism 400 is named as the third fixed platform 410. In some embodiments, the first fixed platform 110, the second fixed platform 120 and the third fixed platform 410 have the same structure.

[0057] like Figure 1 As shown, a specific embodiment of the utility model provides a test fixture for testing at least one characteristic parameter of infrared radiation. In this embodiment, the test fixture includes a first measuring mechanism 100; the first measuring mechanism 100 includes two fixed platforms, and the two fixed platforms are arranged along a first direction.

[0058] The fixed platform includes a support component 101 and a fixed component 102; the fixed component 102 and the support component 101 rotate and cooperate around a first rotation center axis 103, and the first rotation center axis 103 intersects with the first direction; one fixed component 102 is used to install an infrared transmitting module for infrared counter-radiation, and the other fixed component 102 is used to install an infrared receiving module for infrared counter-radiation. Specifically, the fixed component 102 of the first fixed platform 110 is used to install an infrared transmitting module, and the fixed component 102 of the second fixed platform 120 is used to install an infrared receiving module; or, the fixed component 102 of the first fixed platform 110 is used to install an infrared receiving module, and the fixed component 102 of the second fixed platform 120 is used to install an infrared transmitting module.

[0059] In a specific embodiment of the utility model, two fixed platforms are arranged along a first direction, and one of the two fixed components 102 is used to install an infrared transmitting module of the infrared counter-beam, and the other is used to install an infrared receiving module of the infrared counter-beam. The distance between the two fixed platforms can be adjusted along the first direction to change the distance between the infrared receiving module and the infrared transmitting module, thereby realizing the test of the farthest distance of the infrared counter-beam specification. Compared with the existing method of installing the infrared counter-beam on the gate machine for testing, this embodiment can reduce the test error of the farthest distance of the infrared counter-beam specification and improve the test accuracy.

[0060] In a specific embodiment of the utility model, by providing a support component 101 and a fixing component 102, and the fixing component 102 and the support component 101 rotate and cooperate around the first rotation center axis 103, the first rotation center axis 103 intersects with the first direction, and the pitch angle of the infrared receiving module relative to the infrared transmitting module in the vertical direction can be adjusted by rotating any one of the fixing components 102, so as to achieve the measurement of the vertical direction angle of the infrared beam. Compared with the existing method of installing the infrared beam on the gate for testing, this embodiment can reduce the test error of the vertical direction angle of the infrared beam and improve the test accuracy.

[0061] When the infrared beam is installed on the gate to test the vertical direction angle of the infrared beam, it is necessary to repeatedly disassemble and adjust the pitch angle of the infrared receiving module on the gate relative to the infrared transmitting module in the vertical direction. This test method is obviously inefficient. In addition, because the size of the gate is fixed, there may be a large error between the vertical direction angle of the infrared beam and the actual vertical direction angle of the infrared beam. In other words, the vertical direction angle of the test may be much smaller than the actual vertical direction angle of the infrared beam, and there are problems of large test error and low test accuracy. Using the test fixture of this embodiment, when measuring the vertical direction angle, rotating the fixed component 102, the pitch angle of the infrared transmitting module and the infrared receiving module in the vertical direction can be adjusted, avoiding repeated disassembly of the infrared receiving module or the infrared transmitting module, and improving the test efficiency. In addition, because the fixed component 102 of this embodiment can be rotated within a range of at least 180 degrees, the test error of the vertical direction angle can be reduced, and the test accuracy is improved.

[0062] like Figure 3As shown, in some embodiments, the process of using this embodiment to measure the maximum distance of infrared counter-shooting specifications includes: installing the infrared transmitting module on the fixed component 102 of the first fixed platform 110, and installing the infrared receiving module on the fixed component 102 of the second fixed platform 120, at which time the center of the infrared transmitting module is aligned with the center of the infrared receiving module; keeping the position of the first fixed platform 110 unchanged, moving the second fixed platform 120 along the first direction to move the second fixed platform 120 away from the first fixed platform 110, and waiting for the second fixed platform 120 to move to the farthest receivable position of the infrared receiving module, measuring the distance between the infrared receiving module and the infrared transmitting module, which is the maximum distance of infrared counter-shooting specifications.

[0063] like Figure 3 As shown, in some embodiments, the process of using this embodiment to measure the vertical direction pointing angle of infrared radiation includes: installing the infrared transmitting module on the fixing component 102 of the first fixing platform 110, and installing the infrared receiving module on the fixing component 102 of the second fixing platform 120, when the infrared receiving module and the infrared transmitting module are both in the initial position, the center of the infrared transmitting module is aligned with the center of the infrared receiving module; keeping the position of the first fixing platform 110 unchanged, and the fixing component 102 of the first fixing platform 110 does not rotate around the first rotation center axis 103, moving the second fixing platform 120 along the first direction, so that the second fixing platform 120 maintains a first distance from the first fixing platform 110; then, operating the fixing component 102 of the second fixing platform 120 so that the fixing component 102 rotates around the first rotation center axis 103. The axis 103 rotates upward, and the fixed component 102 of the second fixed platform 120 carries the infrared receiving module and rotates upward, so that the infrared receiving module rotates to the lowest receivable position, and the first rotation angle θ1 of the fixed component 102 of the second fixed platform 120 compared to the initial position in the current state is measured; finally, the fixed component 102 of the second fixed platform 120 is operated again to rotate the fixed component 102 downward around the first rotation center axis 103, and the fixed component 102 of the second fixed platform 120 carries the infrared receiving module and rotates downward, so that the infrared receiving module rotates to the highest receivable position, and the second rotation angle θ2 of the fixed component 102 of the second fixed platform 120 compared to the initial position in the current state is measured, then at the first distance, the vertical direction pointing angle φ1 of the infrared radiation satisfies: φ1=θ1+θ2.

[0064] like Figure 4As shown, in some embodiments, the process of measuring the maximum horizontal non-interference distance of infrared counter-radiation using this embodiment includes: installing the infrared transmitting module on the fixed component 102 of the first fixed platform 110, and installing the infrared receiving module on the fixed component 102 of the second fixed platform 120, at this time, the center of the infrared transmitting module is aligned with the center of the infrared receiving module, and the distance between the infrared transmitting module and the infrared receiving module is the maximum distance of the specification; then, keeping the position of the first fixed platform 110 unchanged, moving the second fixed platform 120 along the second direction, so that the second fixed platform 120 moves to the farthest receivable position of the infrared receiving module, wherein the second direction and the first direction are in the same horizontal plane, and the second direction is perpendicular to the first direction; at this time, the moving distance of the second fixed platform 120 in the second direction is the maximum horizontal non-interference distance of the infrared counter-radiation.

[0065] In some embodiments, the test process of the vertical maximum non-interference distance of infrared counter-radiation using this embodiment includes: installing the infrared transmitting module on the fixed component 102 of the first fixed platform 110, and installing the infrared receiving module on the fixed component 102 of the second fixed platform 120, when the infrared receiving module and the infrared transmitting module are both in the initial position, the center of the infrared transmitting module is aligned with the center of the infrared receiving module; keeping the position of the first fixed platform 110 unchanged, moving the second fixed platform 120 upward in the vertical direction, so that the second fixed platform 120 is away from the initial position, and when the second fixed platform 120 rises to the farthest receivable position of the infrared receiving module, the distance that the second fixed platform 120 rises is the vertical maximum non-interference distance of infrared counter-radiation.

[0066] It should be noted that in the specific embodiment of the present utility model, the infrared transmitting module includes at least one infrared transmitting lamp bead; the infrared receiving module includes at least one infrared receiving lamp bead. In the specific embodiment of the present utility model, there is no restriction on the number of infrared transmitting lamp beads of the infrared transmitting module and the number of infrared receiving lamp beads of the infrared receiving module, and the number of infrared transmitting lamp beads and infrared receiving lamp beads can be adjusted according to actual conditions.

[0067] In some embodiments of the present invention, a first angle disk is formed on the support component 101, and a first reference scale line is provided on the fixing component 102; wherein the center of the first angle disk is located on the first rotation center axis 103, and the first reference scale line is used to point to the first angle disk.

[0068] In some other embodiments of the present invention, a first angle disk is formed on the fixing component 102, and a first reference scale line is provided on the supporting component 101; wherein the center of the first angle disk is located on the first rotation center axis 103, and the first reference scale line is used to point to the first angle disk.

[0069] By providing a first angle disc on the supporting component 101 or the fixing component 102 , the rotation angle of the fixing component 102 can be directly determined, avoiding the need to use a measuring tool to measure the vertical direction angle of the infrared beam, thereby improving the test efficiency.

[0070] In some embodiments, the first angle disk is a 360-degree dial; the first angle disk includes first angle scale lines, and the first angle scale lines are arranged around the first rotation center axis 103 so that the center of the first angle disk is located on the first rotation center axis 103.

[0071] In some embodiments, when the center line of the infrared transmitting module is aligned with the center of the infrared receiving module, the first reference scale line is aligned with the zero degree scale line of the first angle disk, so as to facilitate reading the rotation angle of the fixing component 102 .

[0072] In a specific embodiment of the utility model, the support assembly 101 has an installation space, and the fixing assembly 102 includes a fixing member 1021 and an operating member 1022; the fixing member 1021 is arranged in the installation space, and the fixing member 1021 and the support assembly 101 rotate and cooperate around the first rotation center axis 103, and the fixing member 1021 is used to install an infrared transmitting module or an infrared receiving module; the operating member 1022 is arranged outside the installation space, and the operating member 1022 is connected to the fixing member 1021. By rotating the operating member 1022, the fixing member 1021 is driven to rotate around the first rotation center axis 103, thereby improving the convenience of operation.

[0073] Furthermore, a first reference scale line is provided on the operating member 1022, or a first angle disk is formed on the operating member 1022. Because the operating member 1022 is located outside the installation space, it is convenient to check the rotation angle of the fixing assembly 102, further improving the test efficiency.

[0074] like Figure 2 Furthermore, the fixing member 1021 includes a fixing member body 10211 and two connecting rotating shafts 10212; the two ends of the fixing member body 10211 are respectively connected to a connecting rotating shaft 10212, and the two connecting rotating shafts 10212 are respectively corresponding to the two supporting members 1011 and rotate along the first rotation center axis 103; the operating member 1022 is connected to one end of the connecting rotating shaft away from the fixing member body. The fixing member body 10211 is provided with fixing member mounting holes 10213 arranged in an array, and the fixing member mounting holes 10213 cooperate with bolts to realize the fixed installation of the infrared receiving module or the infrared transmitting module. The fixing member mounting holes 10213 arranged in an array can adapt to the fixed installation of infrared receiving modules or infrared transmitting modules of different sizes, thereby improving the application range of the fixing member 1021.

[0075] Specifically, the fixing member 1021 is provided with three rows and three columns of fixing member mounting holes 10213 .

[0076] In a specific embodiment of the present invention, the support assembly 101 includes two support members 1011, and an installation space is formed between the two support members 1011; both ends of the fixing member 1021 respectively rotate with the two support members 1011 in a one-to-one correspondence, thereby improving the movement stability of the fixing member 1021.

[0077] In a specific embodiment of the present utility model, the support assembly 101 further includes a bottom plate 1012; two support members 1011 are arranged on the left and right sides of the upper surface of the bottom plate 1012, and the bottom plate 1012 and the two support members 1011 form an installation space; the fixing member 1021 is installed in the installation space, and the two ends of the fixing member 1021 respectively correspond to the two support members 1011 to rotate around the first rotation center axis 103. The operating member 1022 is located outside the installation space and is fixedly connected to one end of the fixing member 1021. By operating the operating member 1022, the fixing member 1021 can be driven to rotate around the first rotation center axis 103.

[0078] In some embodiments, a first angle plate is formed on the first side of the support member 1011 facing the operating member 1022, and a first reference scale line is provided on the second side of the operating member 1022 perpendicular to the first side of the support member 1011; wherein the first side surface is in contact with the second side surface. When the operating member 1022 is rotated, the operating member 1022 drives the fixing member 1021 to rotate synchronously, and the rotation angle of the fixing assembly 102 can be determined intuitively and quickly through the first reference scale line, thereby determining the vertical direction angle of the infrared beam, further improving the test efficiency.

[0079] It can be understood that the gravity of the fixing component 102 is not greater than the rotational friction between the fixing component 102 and the supporting component 101, so that the fixing component 102 can stop at the target position after rotating to the target position. In other words, the fixing component 102 will not rotate spontaneously under the action of gravity.

[0080] In a specific embodiment of the present invention, the test fixture further includes a base mechanism 200; the base mechanism 200 and the fixed platform slide together along a first direction to facilitate movement of the two fixed platforms, thereby improving operation efficiency and further improving test efficiency.

[0081] In a specific embodiment of the utility model, the base mechanism 200 includes a base 210, a first guide assembly 220 and a second guide assembly 230; the first guide assembly 220 is arranged on the base 210, and the first guide assembly 220 and the fixed platform slide in a first direction; the second guide assembly 230 is arranged on the base 210, the second guide assembly 230 is connected to the first guide assembly 220, and the second guide assembly 230 and the fixed platform slide in a second direction, and the second direction and the first direction are perpendicular to each other in the horizontal plane. By setting the first guide assembly 220, and the first guide assembly 220 and the fixed platform slide in the first direction, the fixed platform can be moved more conveniently along the first direction to adjust the first distance of the two fixed platforms along the first direction, thereby improving the test efficiency of the farthest distance of the infrared radiation specification. By setting the second guide assembly 230, and the second guide assembly 230 and the first guide assembly 220 are connected, the second guide assembly 230 and the fixed platform slide in the second direction, and the second direction and the first direction are perpendicular to each other in the horizontal plane, thereby improving the test efficiency of the horizontal maximum non-interference distance of the infrared radiation.

[0082] like Figure 4 As shown, in some embodiments, the test process of the maximum horizontal non-interference distance using the test fixture of this embodiment includes: first, keeping the distance between the first fixed platform 110 and the second fixed platform 120 in the first direction as the maximum distance of the infrared beam; then, moving the second fixed platform 120 in the second direction to move the second fixed platform 120 to the farthest receivable position of the infrared receiving module, at which time the moving distance of the second fixed platform 120 in the second direction is the maximum horizontal non-interference distance of the infrared beam. That is to say, when the infrared beam is installed on a channel blocking device such as a gate, for two adjacent gates, the horizontal distance between the infrared receiving module of one gate and the infrared transmitting module of the other gate should be greater than the maximum horizontal non-interference distance to prevent the two adjacent gates from interfering with each other.

[0083] It can be understood that the second direction and the first direction are in the same plane, and the first rotation center axis 103 is located above the plane where the first direction and the second direction are located.

[0084] In some embodiments, the base 210 is provided with a first scale 211 along the first direction and a second scale 212 along the second direction. The distance between the first fixed platform 110 and the second fixed platform 120 in the first direction can be quickly determined by the first scale 211. The distance moved by the second fixed platform 120 in the second direction can be quickly determined by providing the second scale 212, thereby improving the test efficiency.

[0085] Furthermore, the first guide assembly 220 includes a first slide rail and a first slide groove; the first slide rail is laid along the first direction, and the first slide rail and the first slide groove are slidably matched along the first direction. Specifically, the first slide rail is arranged on the base 210, and the first slide groove is arranged on the fixed platform.

By moving any of the fixed platforms, the angle between the infrared transmitting module and the infrared receiving module in the horizontal direction can be adjusted, thereby realizing the test of the horizontal direction pointing angle of the infrared beam. In addition, in this embodiment, the fixed platform can only rotate 180 degrees around the second rotation center axis 301, thereby reducing the test error of the horizontal direction pointing angle and improving the test accuracy.

[0093] In some embodiments, the second rotation center axis 301 is vertically arranged, and the first rotation center axis 103 is horizontally arranged.

[0095] Furthermore, a first sliding groove and a second sliding groove are formed at the bottom of the rotating mechanism 300 .

[0099] Furthermore, the second angle disk is a 360-degree dial; the second angle disk includes second angle scale lines, and the second angle scale lines are arranged around the second rotation center axis 301 so that the center line of the second angle disk is located on the second rotation center axis 301.

[0100] Furthermore, when the center of the infrared transmitting module is aligned with the center of the infrared receiving module, the second reference scale line is aligned with the zero degree scale line of the second angle disk, which facilitates reading the horizontal rotation angle of the fixed platform and improves the testing efficiency of the horizontal pointing angle.

[0101] In some embodiments, the rotating mechanism 300 includes but is not limited to a rotating dial. The rotating dial can be purchased to reduce the processing cost of the test tooling. A second angle disc is formed on the rotating dial, and a mounting hole is formed at the beginning of the rotating dial. The center of the mounting hole of the rotating dial coincides with the center of the second angle disc. A support column is provided at the bottom of the base plate 1012 of the support assembly 101. The support column is provided in the mounting hole and can rotate around the second rotation center axis 301 in the mounting hole. Further, the center axis of the support column coincides with the second rotation center axis 301.

[0102] In a specific embodiment of the utility model, the test fixture further includes a second measuring mechanism 400 and a telescopic mechanism 500; the second measuring mechanism 400 is arranged above the first measuring mechanism 100, and the second measuring mechanism 400 includes at least one fixed platform; the telescopic mechanism 500 is arranged between the fixed platform of the second measuring mechanism 400 and the fixed platform of the first measuring mechanism 100, and the telescopic mechanism 500 is used to adjust the vertical distance between the upper and lower fixed platforms. By adjusting the vertical distance between the upper and lower fixed platforms, the vertical maximum non-interference distance test of the infrared counter-radiation can be achieved. Compared with the existing method of testing by installing the infrared counter-radiation on the gate, in this embodiment, the distance between the infrared transmitting module and the infrared receiving module in the vertical direction can be more conveniently adjusted by setting the telescopic mechanism 500, thereby improving the test efficiency. In addition, within the telescopic range of the telescopic mechanism 500, the distance between the infrared transmitting module and the infrared receiving module in the vertical direction can be unrestricted, so the test error of the vertical maximum non-interference distance can be reduced, and the test accuracy can be improved.

[0103] It can be understood that the telescopic range of the telescopic mechanism 500 is not less than the maximum vertical non-interference distance of the infrared radiation.

[0104] In some embodiments, the second measuring mechanism 400 includes two third fixed platforms 410; one of the third fixed platforms 410 is arranged above the first fixed platform 110, and the other third fixed platform 410 is arranged above the second fixed platform 120, which can realize the test of the vertical maximum non-interference distance of at least two pairs of infrared radiation.

At this time, the distance between the third fixed platform 410 and the second fixed platform 120 is the maximum vertical non-interference distance of infrared counter-shooting.

[0106] It should be noted that multiple pairs of infrared transmitting modules are installed on the first gate of the gate, and corresponding multiple pairs of infrared receiving modules are symmetrically installed on the second gate of the gate; in order to avoid the mutual crosstalk between the adjacent left and right infrared beams, the distance between the adjacent left and right infrared beams is required to be greater than the maximum horizontal non-interference distance of the infrared beams. In order to avoid the mutual crosstalk between the upper and lower adjacent infrared beams, the distance between the upper and lower adjacent infrared beams is required to be greater than the maximum vertical non-interference distance of the infrared beams.

[0107] It can be understood that multiple pairs of infrared transmitter modules adjacent to each other in the upper, middle and lower rows inside the first gate of the gate are installed, and multiple pairs of infrared receiving lamp beads are symmetrically installed inside the second gate of the gate. When installing the infrared beams adjacent to each other in the gate, the maximum horizontal non-interference distance and the maximum vertical non-interference distance of the infrared beams need to be considered to avoid crosstalk in the gate signal.

The bottom ends of the two telescopic rods are respectively fixedly connected to the upper ends of the two supporting members 1011 of the second fixed platform 120, and the top ends of the two telescopic rods are fixedly connected to the lower ends of the two supporting rods of the third fixed platform 410. The two telescopic rods are arranged in parallel, and the vertical distance between the second fixed platform 120 and the third fixed platform 410 can be adjusted by adjusting the telescopic rods.
