A laser blocking bar LB is formed in a vertical direction from a predetermined reference.

The blocking bar device may be installed on the crosswalks 12a and 12b to form a blocking bar, and a blocking bar may be formed along the outer boundaries of the left crosswalk 12a and the right crosswalk 12b. The laser beams LB1 and LB2 may extend along the end portions of the crosswalks 12a and 12b in the width direction. To this end, the first and second laser generation modules 13 and 14 may be installed in the sidewalk, and laser beams LB1 and LB2 may be emitted by each laser generation module 13 and 14 to form a blocking bar. . Specifically, the first and second laser generation modules 13 and 14 are installed at the boundaries of the crosswalks 12a and 12b and the pedestrian road, respectively, to generate laser beams along the boundary between the crosswalks 12a and 12b and the roadway 11. (LB1, LB2) can be released. As a result, blocking bars are formed along both border areas of the crosswalks 12a and 12b, and pedestrians can cross the roadway 11 along the areas separated by the blocking bars. Additionally, the vehicle driver can easily recognize the blocking bar and control the vehicle speed, and at least stop at a position that does not violate the crosswalks 12a and 12b due to the blocking bar. Optionally, a third laser generation module 15 can be installed to separate the crosswalks 12a and 12b from each other according to the crossing direction. The third laser beam LB3 emitted by the third laser generation module 15 may have a different height or color from the first and second laser beams LB1 and LB2. Referring to the upper right of FIG. 1, the first and second laser generation modules 13 and 14 include fixing blocks 16a and 16b extending in the vertical direction; and laser emitting means (17a, 17b) disposed on the fixed blocks (16a, 16b). The first and second fixed blocks 16a and 16b may be arranged to face each other with the crosswalks 12a and 12b in between. The first and second fixing blocks 16a and 16b may be formed at a constant height along a vertical direction from the ground and may have the same or similar shapes. At least one laser emitting means (17a, 17b) may be disposed in the first and second fixing blocks (16a, 16b), respectively. The laser beam LB11 may be emitted toward the second fixed block 16b by the laser emitting means 17a disposed on the first fixed block 16a. And the laser beam LB21 may be emitted to the first fixed block 17a by the second laser emitting means 17b disposed in the second fixed block 16b. The first and second laser emitting means (17a, 17b) can emit laser beams (LB11, LB21) to have different heights, thereby creating a blocking bar by the laser beams (LB11, LB21) with a predetermined height. can be formed.

Different laser beams LB11, LB12, and LB13 may be emitted by at least one laser emitting means 17c installed on the third fixed block 16c. A plurality of laser beams LB11, LB12, and LB13 may be formed by the same or different laser emitting means 17c. Additionally, multiple laser beams LB11, LB12, and LB13 may be emitted to have different heights. And a laser blocking bar can be formed by a plurality of laser beams (LB11, LB12, LB13) emitted at different heights. The laser blocking bar can protect pedestrians from vehicles at the crosswalks 12a and 12b, and pedestrians can pass along the crosswalks 12a and 12b by traffic lights. Therefore, it is advantageous for the blocking bar to be formed in conjunction with the signal.

Figure 2 shows an embodiment of the operating structure of the blocking bar device according to the present invention.

Referring to FIG. 2, it further includes an operation interlocking module 22 that interlocks operation with the signal 21 for traffic. The blocking bar device may be operated according to the signal from the signal 21 installed at the crosswalk. For example, when the signal from the signal 21 becomes a green signal for pedestrians, a blocking bar may be created at the crosswalk. The operating state of the signal 21 can be confirmed in the operation interlocking module 22, and the laser generator 26 can be operated to interwork with the signal. Specifically, the signal state, such as red, green or yellow, of the signal 22 may be detected by the operation interlocking module 22. And the laser generator 26 can be activated based on the detected signal condition. The operating time of the laser generator 26 can be set by the time setting module 23. The operating time of red, green or yellow can be stored in advance by the time setting module 22, and the time at which the laser generator 26 should be operated can be determined by the time setting module 22. For example, the time setting module 23 is configured to start operation 2 seconds before the green signal for pedestrians starts at the signal 21 and to stop operation of the laser generator 26 2 seconds after the green signal ends. You can set it. The direction or position of the laser emitted from the laser generator 26 can be adjusted in the direction/position control module 24. The laser emitted from the laser generator 26 may be emitted along a predetermined direction. It needs to be released at a predetermined height. For example, the laser beam should be emitted parallel to the pedestrian crossing direction along the border between the crosswalk and the roadway. Additionally, the laser beam can be emitted to a height of 10 to 40 cm above the ground. The emission direction or emission position of the laser beam can be detected in various ways, for example by light detection means arranged on a stationary block located opposite the laser generator 26. The direction or position of the laser generator 26 may be adjusted based on the results detected by the light detection means. A blocking bar device may be installed at a crosswalk where the signal 21 is not installed. If the signal 21 is not installed, the blocking bar device needs to be activated when people pass through the crosswalk. For this purpose, a walking detection means 25 may be installed, and the walking detection means 25 may be, for example, an ultrasonic detector, a laser detector, or a similar person detection means. When a pedestrian is detected by the pedestrian detection means 25, a detection signal may be transmitted to the laser generator 26. Accordingly, the laser generator 26 can be operated. Afterwards, if the pedestrian is not detected by the pedestrian detection means 25, the operation of the laser generator 26 may be stopped. The blocking bar device can be installed on various types of crosswalks, and the present invention is not limited thereby.
