Description

[Detailed Description of the Invention] The present invention relates to a vehicle entry/exit warning device number ζ that signals pedestrians and general vehicles passing in front of the garage to enter and exit the garage, and alerts them to safety. .

A conventional device of this type is shown in FIG. In the diagram, (1) is the parking lot (garage), (2) is the gate of the parking lot (1), and (3) is "whether the parking lot is full or not" or "the traffic for one vehicle in the parking lot."・Stop command”
(4) is a controller that controls the display (3), (5) is a control line that connects the display (3) and the controller (4), and (6) is a parking Sidewalk in front of car lot (1), (7
) is a pedestrian walking on the road (6), (8) is the road in front of the parking lot (1), and (9) is a vehicle passing on the road (8). 0■
is a manager's room where there is a manager who operates the controller (4).

Next, the operation will be explained.

Usually, the display (3) near the gate (2) of the parking lot (1)
has the function of displaying ``whether the parking lot is full or not'' or ``passing/stopping orders for vehicles in the parking lot.''
Among the cars (9) passing on the roadway (8) in front of the parking lot (1), the car (9) is about to enter the parking lot (1),
And it performs its function only for cars that are about to leave the parking lot (1). That is, the main object of the display (3) is cars using the parking lot.

The display control of the display (3) is performed by the manager or staff member of the manager's room α in the parking lot (1), whether or not the parking lot is currently full or if a car is entering or exiting from the gate (2). This is done by determining whether or not it is OK and operating a controller (4) connected to a display (3) via a control line (5). In addition to human judgment, for example, a loop coil may be buried in each parking space in the parking lot (1).
There is a method of detecting the current ``vacancy'' and ``occupancy'' and automatically displaying it to incoming cars, or placing vehicle detectors such as loop coils and infrared sensors at entrances and exits, and checking the number of incoming cars and There is a method of detecting the number of cars leaving the parking lot and automatically displaying traffic control within the parking lot (1) and the entrance, that is, traffic/stop commands.

A car (9) was passing through a parking lot (1) while passing through a road (8).
), check the display on the roadway (8) edge indicator (3), for example, if the blue lamp is on, and when it is determined that the vehicle is not full, turn right or left and cross the sidewalk (6). , go through the gate (2) and enter the parking lot (1).

In such a device, the safety of pedestrians (7) passing on the sidewalk (6) in front of the parking lot (1) is determined by the display (3).
There is a way to turn on a warning light (for example, flashing yellow), but if a vehicle attempting to enter the parking lot crosses at right angles to the direction of travel of a pedestrian (7), a warning light should normally be installed on the public road. The reality is that the security guard or the driver of the car (9) signals pedestrians verbally or physically that they want to enter or exit the parking lot. In some cases, vehicles enter and leave the warehouse without giving a signal.
There were cases where the safety of pedestrian (7) was threatened due to the lack of thoroughness of this signal. In other words, these parking lots (1)
The display device (3) has only an incomplete function with regard to the safety of pedestrians (7) who are vulnerable to traffic when entering and exiting a car.

Conventional parking lot display devices are constructed as described above, so when entering or exiting the parking lot, the driver must give some kind of signal to pedestrians and other vehicles for safety reasons. Moreover, there are drawbacks such as accidents occurring due to insufficient signaling between drivers of vehicles using the parking lot and pedestrians, or between drivers.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and is equipped with a transmitting device that transmits a signal that signals when a car enters or leaves a garage, and a receiving device that receives this signal on the garage side. By installing a warning device linked to a receiving device near the entrance and exit of the garage, it is possible to alert pedestrians and other vehicles of entering and exiting the garage in advance to alert them to safety concerns. The purpose is to provide a vehicle entry/exit warning device.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows a vehicle entry/exit warning device according to an embodiment of the present invention. In the figure, 21) is a parking lot, (21a) is an entrance/exit, □□□ is a car, (22a) is a transmitting device installed in the car, and (22b) is a transmitting device (22
The transmission activation switch to be operated in order to start transmission of a) is located in the parking lot 21), and is connected to the transmission device (22a).
) is a receiving device that receives the transmission signal from the pedestrian (7) or other control line. In the diagram on the right, (6) is a sidewalk, (7) is a pedestrian, and (8) is a road.

Further, FIG. 3 shows a display device CILL which is an example of the above-mentioned alarm device.

Next, the operation will be explained.

When the car (2) turns right or left and enters the parking lot (21), the transmitting device (22a) transmits a signal indicating the entry in the vicinity of the parking lot (21). The transmission is activated by the driver operating the transmission activation switch (22b). When this signal is received at the entrance/exit of the garage (receiving device installed near 21α), at that timing, the drive signal is transmitted from the receiving device to the sidewalk ('2') via the control line ('2')).
6) is sent to an alarm system installed near the roadway (8).

This warning device (goods) is a device that issues an alarm to pedestrians (7) or other vehicles to draw their attention.As a method of doing so, for example, a device as shown in Figure 3 can be considered. .

That is, 20
This is a display device that is large enough to be visible from up to 30 ya away, and uses a lamp or the like to light up or flash the X-marked part of the display device clll to call out safety precautions to pedestrians (7) or other vehicles. In addition, some pedestrians (7) include people with physical disabilities such as blind people, so at the same time as the display, sounds and sounds (including recently known synchronized sounds) are used to warn people of safety.
It is also possible to output both.

Unlike traffic lights, these devices do not have the force to regulate traffic, so they only request safety cooperation when entering and exiting the garage.

Here, it is assumed that the signal emitted from the transmitting device (22a) is based on known radio waves (including guided radio waves), light, or the like.

Also, it is necessary to limit the transmission output or the distance over which the transmitted signal can reach. In other words, if the signal is transmitted over a long distance, the receiving device (231) will receive the signal much earlier than the car arrives in front of the parking lot (21), causing confusion for pedestrians (7) or other vehicle traffic. This will reduce the reliability of this device, making it impossible to achieve the purpose of this device.Therefore, if the driver of a car (branch) just before entering the parking lot (21) approaches the entrance/exit of the parking lot (21) All you have to do is operate the transmission activation switch (22b) at a position slightly before (21a) so that the signal sent from the transmitting device (22a) is received by the receiving device (c) early. However, since the maximum reach of the signal (service area) is toward the parking embankment while the car is running, approximately 20 to 30 rrL is considered appropriate.

Although we have explained here the operation when a car (+22) enters the parking lot (21), the operation when a car (company) leaves the parking lot (21) is exactly the same, so the explanation is as follows. Omitted.

Also, the lighting time or blinking time of the X mark on the display device t31) shown in FIG. It can be set by

In the above embodiment, the transmission activation switch (22b) is shown, but since the automobile is equipped with a direction indicator, the transmission device (22a) is operated in conjunction with this, i.e. , the transmitting device (22a) may be activated at 1 o'clock right turn or 1 o'clock left turn. In this case, as shown in Figure 2, when entering or exiting a parking lot, the driver must operate the turn signal to make a ``right turn'' or ``left turn.'' Installing the device does not require any additional switch operations, so there will be no extra effort on the part of the driver.

As described above, the vehicle entry/exit warning device according to the present invention is equipped with a transmitting device that transmits a signal that signals the entry or exit of a vehicle, a receiving device is installed on the garage side to receive this signal, and further includes: Since an alarm device linked to a receiving device is placed near the garage entrance, it is possible to automatically notify pedestrians and other vehicles of entering and exiting the garage, which has the effect of alerting pedestrians and others to safety concerns. be.
