［作 用］
上記した本発明の構成に於いて、車両の通過速度変化に
伴って変化する車両の側面パターンは、以下の如くして
パターン補正、並びにパターン修正できる。[Function] In the configuration of the present invention described above, the side pattern of the vehicle that changes as the passing speed of the vehicle changes can be corrected and corrected as follows.
即ち、２組の光電スイッチ群の車両の通過に伴う、立上
り又は立下りの時間差から、車両の平均速度が解るため
、車両の時系列パターンを標準時間の圧縮パターンに補
正できる。That is, since the average speed of the vehicle can be determined from the time difference between the rise and fall of the two photoelectric switch groups as the vehicle passes, the time series pattern of the vehicle can be corrected to a compressed standard time pattern.
又、２組の光電スイッチの立上り時間差と立下り時間差
が大きい場合、立上りと立下りまでの中間速度は、両速
度の内挿法で求まるため、順次補正値を修正することも
できる。Furthermore, when the difference in rise time and fall time between two sets of photoelectric switches is large, the intermediate speed between rise and fall can be determined by interpolation of both speeds, so that the correction value can be corrected sequentially.
又、通過中の速度変化に対しても車高の変化は、２組の
光電スイッチ群とも、同じ軌跡を辿るから、車高の特徴
ある変化点の時間差からも速度変化を検出することがで
き、その中間の速度変化に対しでも圧縮パターンを修正
できる。In addition, changes in vehicle height follow the same trajectory for both photoelectric switch groups in response to changes in speed during passing, so changes in speed can be detected from the time difference between characteristic points of change in vehicle height. , the compression pattern can be modified even for speed changes in between.
従って、車両の通過速度が時々刻々変化しても間延びす
ること無く、正確な車両の側面パターンが得られ、標準
パターンとの比較により精度の高い車種判別が可能とな

。It has a pair of first and second detectors formed by vertically arranging a plurality of photoelectric switches, and each of the detectors is arranged a predetermined distance apart in the direction in which the vehicle travels on the passage. a vehicle detection mechanism, a scanning means for time-divisionally scanning the photoelectric switches provided on the first and second detectors, and a vehicle passage detection mechanism for the photoelectric switches provided on the first and second detectors; first and second input pattern memories for storing switching operation patterns associated with each detector in time series for each of the detectors; and means for correcting and time-compressing the patterns stored in the input pattern memories according to the passing speed of the vehicle. , a vehicle type file storing a standard pattern for each vehicle type measured and set in advance, and means for comparing and collating the time-compressed pattern with the standard pattern in the vehicle type file to determine the vehicle type of a passing vehicle. A vehicle type identification device characterized by:
