Description
Technical Field
The invention relates to an electronic target light curtain technology, in particular to a double-side double-receiver array light curtain, wherein two receiver arrays are arranged on each of two opposite sides of a frame structure to form a whole optical detection coordinate surface, so that the phenomenon that one receiver array needs to be arranged at a folded angle or the overlapping coupling phenomenon of two adjacent receiver arrays staggered back and forth can be avoided, each side is convenient to independently seal, cross joint sealing is not needed, the difficulty of an installation process is reduced, the target reporting precision and the target reporting reliability are improved, and the faults possibly faced by use and maintenance are reduced.
Background
The light curtain electronic target generally encloses a quadrilateral optical detection coordinate plane through two transmitters and two receiver arrays, the transmission angles of the two transmitters are both 90 degrees, one transmitter is positioned at the lower right corner, and the other transmitter is positioned at the lower left corner. A receiver array corresponding to the lower right transmitter has two edges, an upper edge and a left edge, which join in the upper left corner to form a dog-ear (e.g., a vertical join corner). Another receiver array corresponding to the lower left corner transmitter has two edges, an upper edge and a right edge, which join in the upper right corner to form a dog-ear (e.g., a vertical join angle). The inventor finds that the light path sealing at the corner structure is difficult to realize, the corner sealing structure may cause the receiving interference to the 45-degree diagonal light path, the installation and maintenance difficulty is increased, and the connection precision of the receiver array at the corner is difficult to guarantee during the installation. Even if one receiver array with two edges connected through a folded angle is split into two independent edges, namely two receiver arrays, and then front and back staggered arrangement is carried out, the lapping coupling phenomenon still exists for two adjacent receiver arrays staggered front and back, namely, cross joint sealing is still needed. The inventors believe that if two receiver arrays are provided on each of an opposite side of the frame structure to form the entire optical detection coordinate plane, it is no longer necessary to provide receiver arrays on adjacent sides (e.g., receiver arrays on only the left and right sides, but no receiver arrays on both the top and bottom sides), which enables separate sealing on each of the opposite sides, without cross-splice sealing, reducing process requirements and improving reliability. In view of the above, the present inventors have completed the present invention.

The first transmitter is located on the front layer, the second transmitter is located on the rear layer, the third transmitter is located on the front layer, and the fourth transmitter is located on the rear layer.
The first transmitter, the first receiver array, the third transmitter, and the third receiver array are located on a same plane, and the second transmitter, the second receiver array, the fourth transmitter, and the fourth receiver array are located on a same plane.
The first receiver array receives the upper right corner and left upper light emitted by the first transmitter to cover the lower left area, the second receiver array receives the upper right corner and left lower light emitted by the second transmitter to cover the upper left area, the third receiver array receives the lower left corner and right upper light emitted by the third transmitter to cover the lower right area, and the fourth receiver array receives the upper left corner and right lower light emitted by the fourth transmitter to cover the upper right area.

The invention has the following technical effects: the double-side double-receiver array light curtain can form the whole optical detection coordinate plane by arranging the double-receiver array on each side of the opposite side, and reduces one receiver array side compared with the left, upper and right 3 receiver array sides related in the prior art, namely, only the left and right sides have the receiver arrays without the upper side receiver array or the lower side receiver array, namely, the phenomenon that one receiver array needs to be arranged at a folding angle or the overlapping coupling phenomenon of two adjacent receiver arrays staggered front and back can be avoided. The method facilitates independent sealing of each side, does not need cross joint sealing, and reduces the difficulty of the installation process, thereby being beneficial to improving the target reporting precision and the target reporting reliability and reducing the possible faults faced by use and maintenance.
Each side in an opposite side sets up two receiver arrays, and two receiver arrays with same side can be kept apart through modes such as different spaces or different wavelength or different directions, receive the light that respectively corresponds transmitter transmitted to one mode, realize the cross coverage of the detection light in whole detection target face to realize bullet detection at whole target face. This correspondence can also be understood by four transceiving groups. The first transmitter corresponds to the first receiver array to form a first transceiving group, the second transmitter corresponds to the second receiver array to form a second transceiving group, the third transmitter corresponds to the third receiver array to form a third transceiving group, and the fourth transmitter corresponds to the fourth receiver array to form a fourth transceiving group. The first transceiving group, the second transceiving group, the third transceiving group and the fourth transceiving group are crossed with each other to cover the whole detection area. The first transceiving group and the second transceiving group are separated through space discrimination, wavelength discrimination or direction discrimination, so that signals transmitted by the transmitter of each transceiving group are only received by the receiver array of the transceiving group. The third transceiving group and the fourth transceiving group are separated through space discrimination, wavelength discrimination or direction discrimination, so that signals transmitted by the transmitter of each transceiving group are only received by the receiver array of the transceiving group.
The isolation for spatial differentiation is illustrated as follows: when two transceiving groups on the same side are arranged, the two transceiving groups are isolated in space, and the receiver array of each transceiving group can only receive signals transmitted by the transmitter of the transceiving group. For example, two transceiving groups on the same side are arranged on a front layer and a rear layer, a first transceiving group is arranged at the front, a second transceiving group is arranged at the rear, a third transceiving group is arranged at the front, and a fourth transceiving group is arranged at the rear, so that even if the wavelengths of all the transceiving groups are the same, a crossed light curtain can be formed by space isolation.
The isolation for wavelength discrimination is illustrated as follows: the two transceiving groups on the same side work on different wavelengths, and the receiver array of each transceiving group can only receive signals transmitted by the transmitter of the transceiving group. For example, the transmitter of the first transceiving group transmits light with a wavelength of 650nm, the first receiver array only receives light with a wavelength of 650nm, the transmitter of the second transceiving group transmits light with a wavelength of 940nm, and the second receiver array only receives light with a wavelength of 940nm, so that the crossed light curtain can be formed even if the first transceiving group and the second transceiving group are arranged on the same layer.
The receiver is arranged on two opposite sides of the light curtain with double receiver arrays at two sides, and the cross connection of the receiver arrays is avoided on the premise that the cross light curtain covers the whole target surface, so that the receiver which is in cross connection is prevented from being sealed, the requirement of a production process is reduced, and the reliability of a product is improved. The invention has the following characteristics: 1. the receivers are arranged on opposite sides. 2. Each side contains at least 2 receiver arrays. 3. The transmitters corresponding to the receiver arrays are respectively arranged at two ends of the opposite side of the receiver arrays and respectively irradiate the receiver arrays which are staggered front and back. 4. The receiver array only needs to be sealed on each side, and cross-joint sealing is not needed, so that the process requirement is reduced. 5. Light curtain overlapping: the regional light curtain of upper left region and upper right overlaps, and the regional light curtain of upper left region and lower right overlaps, can reduce the required precision that the light curtain links up.
