In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] This embodiment provides a light sensor assembly 3, which is used in a measurement system. Figure 4 As shown, the measurement system includes an optical signal transmitting component 1, a control module 2 and the optical sensor component 3. The optical signal transmitting component 1 is used to be set on the object to be measured 4 and transmit the optical signal 6; the optical sensor component 3 is arranged opposite to the optical signal transmitting component 1, and is used to receive the optical signal 6 and output the first optical sensing signal through the first soldering pad 311, and output the second optical sensing signal through the second soldering pad 312; the control module 2 is connected to the first soldering pad 311 and the second soldering pad 312 of the optical sensor component 3, and is used to receive the first optical sensing signal and the second optical sensing signal to generate a measurement detection signal.

[0034] Exemplarily, the optical signal transmitting component 1 includes a laser transmitter or an infrared transmitter. It is understandable that the optical signal 6 can be a laser signal 6 or an infrared light signal 6. Optionally, the optical signal 6 can present different shapes, such as a dot, a straight line or a cross line. The object to be measured 4 is an object to be measured. It can be selected according to actual needs. Exemplarily, the object to be measured 4 includes an object whose horizontal offset or tilt offset needs to be measured. For example, the object to be measured 4 includes a train track, or a bridge, etc.

[0035] In one application scenario, the measurement system is applied to the rails of a train to detect whether the rails of the train are horizontally offset. Exemplarily, the optical signal emitting component 1 and the optical sensor component 3 are relatively arranged on two rails of the train. When any one of the rails is horizontally offset, the optical signal emitting component 1 emits an optical signal 6 to the optical sensor component 3 that is offset. After the optical sensor component 3 senses that the optical signal 6 is offset, it outputs the first optical sensing signal and the second optical sensing signal to the control module 2, so that the control module 2 generates a measurement detection signal, thereby automatically realizing the horizontal offset detection of the train rails, and improving the applicability and measurement efficiency of the measurement system.

[0036] This embodiment provides a light sensor assembly 3, such as Figure 1 As shown, it includes a first substrate 31, at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33; at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 are arranged side by side and staggered on the first substrate 31; the first substrate 31 is provided with a first solder pad 311 connected to the first photosensitive array, and a second solder pad 312 connected to the second photosensitive array; the first solder pad 311 and the second solder pad 312 are used to connect the control module 2.

[0037] Optionally, the first substrate 31 may be a fiberglass substrate or an aluminum substrate.

[0038] As an example, at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 are arranged side by side and staggered on the first substrate 31. Exemplarily, at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 can be welded side by side and staggered on the first substrate 31 by means of a conductive material. Optionally, the conductive material includes conductive materials such as solder paste, conductive glue, conductive metal wire, etc. The welding method can be high-temperature welding, ultrasonic welding or laser welding. In this example, at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 are arranged side by side and staggered on the first substrate 31, thereby improving the measurement density and improving the sensing accuracy of the optical signal 6.

[0039] As an example, the first substrate 31 is provided with a first solder pad 311 connected to the first photosensitive array, and a second solder pad 312 connected to the second photosensitive array; the first solder pad 311 and the second solder pad 312 are used to connect to the control module 2, so as to facilitate outputting the first light sensing signal output by the first photosensitive array to the control module 2 through the first solder pad 311, and outputting the second light sensing signal output by the second photosensitive array to the control module 2 through the second solder pad 312, so that the control module 2 receives the first light sensing signal and the second light sensing signal to generate a measurement detection signal.

[0040] In this embodiment, the optical sensor assembly 3 includes a first substrate 31, at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33; at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 are arranged side by side and staggered on the first substrate 31, so as to improve the measurement density and improve the sensing accuracy of the optical signal 6; the first substrate 31 is provided with a first solder pad 311 connected to the first photosensitive array, and a second solder pad 312 connected to the second photosensitive array; the first solder pad 311 and the second solder pad 312 are used to connect to the control module 2, so as to accurately and automatically detect the optical signal 6 used to measure the object 4 through the optical sensor assembly 3, so as to adapt to more measurement scenarios and improve the measurement efficiency.

[0041] In one embodiment, each row of the first photosensitive array includes at least two first photoreceptors 321 spaced apart from each other; each row of the second photosensitive array includes at least two second photoreceptors 331 spaced apart from each other; and the space between two adjacent first photoreceptors 321 is aligned with one second photoreceptor 331 .

[0042] As an example, due to limitations of the welding process, at least two spaced-apart first photoreceptors 321 in each row of the first photosensitive array cannot be tightly connected. Therefore, when the light signal 6 hits the gap between at least two spaced-apart first photoreceptors 321, it cannot be detected by the first photoreceptor 321. Therefore, in this example, by ensuring that the interval position between two adjacent first photoreceptors 321 is aligned with a second photoreceptor 331, the light signal 6 that cannot be detected by the first photoreceptor 321 is sensed by the second photoreceptor 331, thereby improving the layout density of the first photoreceptors 321 and the second photoreceptors 331 on the first substrate 31, thereby improving the detection density.

[0043] Furthermore, each of the first photoreceptors 321 in two adjacent rows of the first photosensitive arrays is aligned one by one, and each of the second photoreceptors 331 in two adjacent rows of the second photosensitive arrays is aligned one by one.

[0044] For example, when the light signal 6 is a linear light signal 6, when the first photoreceptors 321 aligned in two connected rows of first photosensitive arrays cannot detect the linear light signal 6, the linear light signal 6 can be detected by the second photoreceptors 331 aligned in two adjacent rows of second photosensitive arrays, thereby improving the detection density and further improving the measurement accuracy.

[0045] In one embodiment, the number of the first photoreceptors 321 in the first photosensitive array may be the same as or different from the number of the second photoreceptors 331 in the second photosensitive array, as long as the number of the first photoreceptors 321 in each first photosensitive array and the number of the second photoreceptors 331 in each second photosensitive array are greater than or equal to 1.

[0046] Preferably, the number of the first photoreceptors 321 in the first photoreceptor array is the same as the number of the second photoreceptors 331 in the second photoreceptor array.

[0047] In this embodiment, the number of first photoreceptors 321 in the first photosensitive array is ensured to be the same as the number of second photoreceptors 331 in the second photosensitive array, so that the first photoreceptors 321 and the second photoreceptors 331 can be more evenly distributed on the first substrate 31, thereby ensuring the sensing accuracy of the light sensing component.

[0048] In one embodiment, the spacing distance between any two first photoreceptors 321 is equal to the spacing distance between any two second photoreceptors 331. In this embodiment, the spacing distance between any two first photoreceptors 321 is equal to the spacing distance between any two second photoreceptors 331, so as to ensure that any area on the first substrate 31 can sense the optical signal 6 emitted by the optical signal emitting component 1.

[0049] In one embodiment, the spacing distance is less than or equal to the side length of the second photoreceptor 331 .

[0050] As an example, if the first photoreceptor 321 is square, the side length may be the length of any side of the first photoreceptor 321. If the first photoreceptor 321 is rectangular, the side length is the length of the short side of the first photoreceptor 321.

[0051] In this embodiment, the spacing distance is ensured to be less than or equal to the side length of the first photoreceptor 321. When the light signal 6 hits the spacing position between two adjacent first photoreceptors 321, the light signal 6 can be detected by the second photoreceptor 331 aligned with the spacing position of the two connected first photoreceptors 321, thereby ensuring that the light signal 6 hitting the first substrate 31 can be detected by the first photoreceptor 321 and / or the second photoreceptor 331, thereby improving the measurement density.

[0052] In one embodiment, at least two first pads 311 and at least two second pads 312 are arranged in parallel on both sides of the first substrate 31; the first photoreceptors 321 in two adjacent rows of first photosensitive arrays are aligned one by one; the mutually aligned first photoreceptors 321 are connected to a first pad 311; the second photoreceptors 331 in two adjacent rows of second photosensitive arrays are aligned one by one; the mutually aligned second photoreceptors 331 are commonly connected to a second pad 312.

[0053] As an example, each first photoreceptor 321 in each row of the first photosensitive array is welded on the first substrate 31 via a third pad 313, and each third pad 313 is connected to a fifth pad 315 via a metal line, and the fifth pad 315 is used to receive a first power supply signal. Each second photoreceptor 331 in each row of the second photosensitive array is welded on the first substrate 31 via a fourth pad 314, and each fourth pad 314 is connected to a sixth pad 316 via a metal line, and the sixth pad 316 is used to receive a second power supply signal. The first power supply signal and the second power supply signal are of the same magnitude.

[0054] As an example, a seventh pad 317 is provided at the periphery of the third pad 313 in each row of the first photosensitive array, and each seventh pad 317 is connected to a first photoreceptor 321 through a bonding wire. Two adjacent rows of seventh pads 317 are aligned one by one, and the aligned seventh pads 317 are connected to each other through metal vias and to a first pad 311, so that the first photoreceptors 321 aligned with each other are connected to a first pad 311. An eighth pad 318 is provided at the periphery of the third pad 313 in each row of the second photosensitive array, and each eighth pad 318 is connected to a second photoreceptor 331 through a bonding wire. Two adjacent rows of eighth pads 318 are aligned one by one, and the aligned eighth pads 318 are connected to each other through metal vias and to a second pad 312, so that the second photoreceptors 331 aligned with each other are connected to a second pad 312. When the control module 2 is connected to each first pad 311 and each second pad 312 respectively, the position of the optical signal 6 on the first substrate 31 can be determined, and whether the optical signal 6 is offset, thereby achieving the purpose of measuring horizontal offset or vertical offset.

[0055] In one embodiment, if Figure 2 As shown, the first substrate 31 is annular, so that the first photoreceptors 321 and the second photoreceptors 331 on the first substrate 31 are distributed in annular shape, thereby achieving the purpose of measuring the angle deviation.

[0056] In one embodiment, if Figure 3 As shown, the optical sensor assembly 3 further includes an outer layer of protective colloid 34 , and the outer layer of protective colloid 34 is wrapped around the first photosensitive array 32 and the second photosensitive array 33 .

[0057] Optionally, the outer protective colloid 34 may be made of silica gel, silicone resin or epoxy resin. Furthermore, dyes may be added to adjust the sensitivity to the optical signal 6 or to receive only the optical signal 6 of a specific wavelength.

[0058] In this embodiment, the outer layer protective colloid 34 is wrapped around at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 to protect the at least two rows of first photosensitive arrays 32 and at least two rows of second photosensitive arrays 33 .

[0059] This embodiment provides a measurement system, such as Figure 4 As shown, it includes an optical signal transmitting component 1, a control module 2 and the above-mentioned optical sensor component 3; the optical signal transmitting component 1 is used to be set on the object to be measured 4 to transmit the optical signal 6; the optical sensor component 3 is arranged opposite to the optical signal transmitting component 1, and is used to receive the optical signal 6 and output the first optical sensing signal through the first pad 311, and output the second optical sensing signal through the second pad 312; the control module 2 is connected to the first pad 311 and the second pad 312 of the optical sensor component 3, and is used to receive the first optical sensing signal and the second optical sensing signal to generate a measurement detection signal.

[0060] As an example, the control module 2 can be integrated on the optical sensor assembly 3, or can be independently provided, and the control module 2 is connected to the first pad 311 and the second pad 312 of the optical sensor assembly 3. Preferably, the control module 2 can be integrated on the optical sensor assembly 3 to improve the integration of the measurement system.

[0061] In one embodiment, the measuring system further comprises an angle adjustment bracket 5 for fixing the optical sensor assembly 3 , and the angle adjustment bracket 5 is used to adjust the tilt angle of the optical sensor assembly 3 .

[0062] In this embodiment, if Figure 5 As shown, the measuring system also includes an angle adjustment bracket 5 for fixing the optical sensor assembly 3, and the angle adjustment bracket 5 is used to adjust the inclination angle of the optical sensor assembly 3, so that by adjusting the inclination angle of the optical sensor assembly 3, it is possible to measure whether a vertical offset occurs in the inclined object 4.

By adjusting the position of the fastening structure 52 on the guide ring 51, the inclination angle of the optical sensor assembly 3 is adjusted to be consistent with the inclination angle of the object to be measured 4, so as to detect in real time whether the object to be measured 4 has a vertical deviation, thereby realizing the measurement of the object to be measured 4 with a tilt measurement setting.
