In the case of this blocking bar, red LEDs and yellow LEDs are alternately arranged. And when a train etc. pass a railroad crossing, a interruption | blocking bar | burr descend | falls, and it controls so that red LED and yellow LED may light simultaneously at the timing. In the case of the blocking bar disclosed in Patent Document 1, although light of a plurality of colors can be emitted, since they emit at the same timing, the merit of using light of a plurality of colors is small.

  On the other hand, Patent Document 2 discloses a blocking bar that emits a plurality of colors of light at different timings for each color (paragraph numbers 0015-0016 and 0020-0021 of Patent Document 2). In the case of this blocking bar, the red LED and the blue LED are alternately arranged. When the train detection sensor detects the approach of the train, the display control unit blinks the red LED, and then the blocking bar changes from vertical to horizontal. To turn. As a result, the driver can be alerted to the vehicle stop position as the train approaches. When the train passes, the display control unit turns off the red LED and turns on the blue LED after the blocking bar rotates from the horizontal to the vertical direction. Thereby, it is possible to inform the driver that the vehicle can be transmitted safely as the train passes.

  The control unit 101 is constituted by a microcontroller, for example, and this microcontroller is provided with a memory for storing a program. When the microcontroller executes the program stored in the memory, the control unit 101 performs display control of the LED array 105. More specifically, the control unit 101 controls the operation of the drive unit 106 according to a program, whereby the drive unit 106 includes the first LED arrays 11a and 11b and the second LED arrays 12a and 12b that constitute the LED array 105.

  In the present embodiment, the power necessary for lighting the LED array 105 is supplied from the breaker side. However, a solar power supply unit may be provided on the side of the blocking bar 1 so that power for lighting the LED array 105 may be provided by the blocking bar 1 alone.

[Operation of blocking bar]
Hereinafter, the operation of the blocking bar 1 configured as described above will be described. First, the lighting operation of the third LED arrays 13a and 13b that emit white light will be described. When the control unit 101 determines whether or not the brightness around the bar body 10 exceeds a predetermined threshold based on the signal input from the illuminance sensor 104, and determines that it exceeds the threshold, The third LED arrays 13a and 13b are turned on via the drive unit 106. Thereby, when the circumference | surroundings of the bar main body 10 become dark, the lower part of the bar main body 10 can be illuminated. Thereafter, when the control unit 101 determines that the brightness around the bar body 10 is equal to or less than the threshold, the third LED arrays 13a and 13b are turned off.

（２）第２モード

上記において、“起立姿勢”はバー本体１０が垂直になっている状態を、“倒伏姿勢”は同じく水平になっている状態をそれぞれ意味している。バー本体１０が起立姿勢で停止している場合、ゲートは開状態となり、車両の通行が許可される。他方、バー本体１０が倒伏姿勢で停止している場合、ゲートは閉状態となり、車両の通行が禁止される。また、“第１中間姿勢”は、バー本体１０が起立姿勢から倒伏姿勢へ移行する途中における特定の時点の状態を、“第２中間姿勢”は、バー本体１０が倒伏姿勢から起立姿勢へ移行する途中における特定の時点の状態を、それぞれ意味している。 Next, the lighting operation modes of the first LED arrays 11a and 11b and the second LED arrays 12a and 12b that emit two colors of light will be described.
In the present embodiment, the following two modes are prepared: a first mode and a second mode.
(1) First mode

(2) Second mode

In the above, “standing posture” means a state in which the bar body 10 is vertical, and “falling posture” means a state in which the bar body 10 is also horizontal. When the bar main body 10 is stopped in the standing posture, the gate is opened and the vehicle is permitted to pass. On the other hand, when the bar main body 10 is stopped in the lying posture, the gate is closed and the passage of the vehicle is prohibited. The “first intermediate position” is a state at a specific point in the middle of the transition of the bar body 10 from the standing position to the lying position, and the “second intermediate position” is the state where the bar body 10 is shifted from the lying position to the standing position. It means the state at a specific point in the middle of doing.

  As shown in the above table, the same operation is performed in the first mode and the second mode except for the difference between whether the green light is on or flashing. Which of the first mode and the second mode is performed is set using the input unit 102 as described above. Hereinafter, the description will be given assuming that the first mode is set.

  FIG. 5A is a diagram illustrating a display state when the bar main body 10 shifts from the standing posture to the lying posture, and FIG. 5B is a diagram illustrating a display state when similarly shifting from the lying posture to the standing posture. When the bar body 10 is in the standing posture, the control unit 101 lights the first LED arrays 11a and 11b and the second LED arrays 12a and 12b in green. When the control unit 101 determines that the bar body 10 has rotated to reach the first intermediate posture by the signal input from the tilt sensor 103, as shown in FIG. 5A, the first LED arrays 11a and 11b, and The second LED arrays 12a and 12b are lit red. That is, the bar body 10 is switched from green to red at the timing when the bar body 10 reaches the first intermediate posture. Thereafter, the first LED arrays 11a and 11b and the second LED arrays 12a and 12b continue to be lit in red until the bar body 10 is stopped from the first intermediate posture to the lying posture and in the lying posture.

  On the other hand, when the control unit 101 determines that the bar body 10 is rotated and reaches the second intermediate posture from the lying posture by the signal input from the tilt sensor 103, as shown in FIG. 5B, the first LED array 11a is used. And 11b and the second LED arrays 12a and 12b are lit in green. That is, the bar body 10 is switched from red to green at the timing when the bar body 10 reaches the second intermediate posture. Thereafter, the first LED arrays 11a and 11b and the second LED arrays 12a and 12b continue to be lit in green until the bar body 10 stops from the second intermediate posture to the standing posture and in the standing posture.

  In the above-described operation, it can be appropriately set by a program whether the inclination angle of the bar body 10 is determined to have reached each of the first intermediate posture and the second intermediate posture. The first intermediate posture and the second intermediate posture are set based on the examination result by examining how much red and green should be lit while the bar body 10 is rotating. It will be. The first intermediate posture and the second intermediate posture may have the same inclination angle or different inclination angles.

  As described above, in the blocking bar 1 according to the present embodiment, when the bar main body 10 is stopped in the standing posture or the lying posture, the light emission color is not switched, but on the way or from the standing posture to the lying posture. The light emission color changes during the transition from the posture to the standing posture. Therefore, the emission color is switched while the bar body 10 is rotating, and a display rich in visual change can be performed. Therefore, effects such as the ability to promote alerting the driver of the vehicle that is about to pass through the gate are produced.

  In addition, as described above, not only when the bar body 10 is stopped in the lying posture, but also during the period until the second intermediate posture is reached, the operation for continuously lighting red is as follows. There are advantages. When the bar body 10 is stopped in the lying posture and the red light is lit, the gate is closed, so the driver stops the vehicle before the bar body 10 until the gate is opened. Then, when it is determined that the circuit breaker opens the gate, the bar body 10 starts to rotate and starts to shift from the lying posture to the standing posture. At this time, in the present embodiment, red remains lit until the bar body 10 reaches the second intermediate posture. Although the driver can recognize that the bar body 10 has started to rotate, the driver can determine that the vehicle should not start passing because the red color is continuously lit. Thereby, it is possible to prevent the driver from suddenly starting the vehicle at the start of the rotation of the bar body 10 in the lying posture.

  Thereafter, when the bar body 10 switches from red lighting to green lighting at the timing when the bar body 10 reaches the second intermediate posture, the driver who has detected the change in the color recognizes that the vehicle should start to pass at this time. . That is, the start of traffic of the vehicle is prompted by the color change. Shortly thereafter, the bar main body 10a is in a standing posture, and after the gate is opened, the vehicle smoothly passes through the gate. In this way, it is possible to prompt the vehicle to pass at the timing when the gate is opened.

  In the case of the blocking bar 1 according to the present embodiment, the blocking bar 1 itself detects the tilt angle of the bar body 10 and performs the lighting operation of the LED array 105 according to the tilt angle. Become. When lighting control is performed by a breaker, troublesome work such as special wiring is required to output the control signal to the breaker bar, or the breaker control program needs to be updated. However, in this embodiment, since the blocking bar 1 can perform display control by itself, such trouble can be omitted. However, it may be configured such that the shut-off bar 1 is instructed to turn on / flash / turn off from the control device of the breaker.

(Other embodiments)
In the above-described embodiment, the first LED arrays 11a and 11b and the second LED arrays 12a and 12b include red and green two-color LEDs, but each LED array has a red single-color LED and a green single-color LED. A light emitting LED may be provided. In this case, a plurality of LEDs that emit the same color are driven together, thereby switching the multi-color light as in the above-described embodiment. In this case, a mode in which one or a plurality of red monochromatic LEDs and green monochromatic LEDs are alternately arranged is assumed.

  Further, in the above-described embodiment, the bar main body 10 is composed of the two bar-shaped members of the first bar main body 10a and the second bar main body 10b. You may be comprised with the rod-shaped member more than this.

  In the above-described embodiment, when the bar body 10 is in the standing posture, both the first bar body 10a and the second bar body 10b are in the standing posture, but the second bar body 10b located on the distal end side. Can be configured not to stand upright. FIG. 6 is a front view showing the configuration of the blocking bar according to another embodiment in the lying posture, and FIG. 7 is a front view showing the configuration of the blocking bar in the standing posture. As shown in FIG. 6, the blocking bar 2 includes a bar main body 10 including a first bar main body 10 a and a second bar main body 10 b as in the case of the blocking bar 1. Here, plate-like connecting members 31 and 32 are connected to the front end portion of the first bar main body 10a and the rear end portion of the second bar main body 10b, respectively. These connecting members 31 and 32 are provided with holes, and pins 33 are inserted into the holes. The second bar main body 10b is rotatably connected to the first bar main body 10a via a pin 33, and cannot rotate when the first bar main body 10a is in the lying posture when the first bar main body 10a is in the standing posture. It is supported as such. Thereby, as shown in FIG. 7, when the bar main body 10 is in the standing posture, the first bar main body 10a is in the standing posture, while the second bar main body 10b is maintained in the lying posture. As described above, when the bar main body 10 is in the standing posture, the bar main body is bent at approximately 90 degrees, and a display that is more varied can be realized.

  In the above-described embodiment, when the bar body 10 reaches the first intermediate position or the second intermediate position during the period in which the bar body 10 is rotating, the first LED arrays 11a and 11b and the second LED array. Although the lighting colors 12a and 12b are switched simultaneously, this switching may be performed gradually. Specifically, the drive unit 106 is configured to be able to individually drive each LED in the first LED arrays 11a and 11b and the second LED arrays 12a and 12b, and the bar body 10 is in a standing posture (all LEDs are green). When the transition from the lighting state to the lying posture is started, a part of the LEDs is lit in red, gradually increasing the proportion of the LEDs that are lit red, and when the bar body 10 reaches the lying posture all The control unit 101 controls the drive unit 106 so that the LED is lit red. On the other hand, when the bar body 10 shifts from the lying posture (a state in which all the LEDs are lit in red) to the standing posture, a part of the LEDs is lit in green at the timing through the transition, and the green light is gradually turned on. The control unit 101 controls the drive unit 106 so that the ratio of the LEDs is increased and all the LEDs are lit in green when the bar body 10 reaches the standing posture. In this case, for example, gradually from green lighting to red lighting or from red lighting to green lighting from the shaft support portion of the bar main body 10 to the front end portion, that is, from the rear end portion of the first bar main body 10a to the front end portion of the second bar main body 10b. It is assumed that the light emission operation of each LED is controlled so as to change to lighting. Needless to say, the green color may gradually change from red to red or from red to green. As described above, by gradually switching the color while the bar main body 10 is rotating, it is possible to further promote alerting the driver.

  It should be noted that other embodiments can be realized by combining the above-described embodiments.

  The blocking bar and its display control method of the present invention are useful as a blocking bar used in a parking lot barrier and its display control method.
