Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking display device in a self-propelled parking lot which can electrically display a parking state of a vehicle including a full display at a vehicle entrance position of the parking lot. About.

2. Description of the Related Art In a self-propelled parking lot, a driver himself drives a vehicle to a parking space and parks the vehicle. When the driver exits, the driver himself drives from the parking space and exits.

In self-propelled parking lots, there are two types: one that manages entering and exiting vehicles at the entrance and exit, and one that relies exclusively on free use by shoppers, such as a parking lot attached to a store, in order to collect parking fees. is there.

Problems to be Solved by the Invention In such a self-propelled parking lot, since a driver outside the parking lot cannot know the parking situation inside the parking lot, a vehicle enters a fully-filled parking lot or searches inside the parking lot to find an empty position. There is a problem that the inside of the hall tends to be unduly crowded due to the running of the vehicle.

Therefore, an object of the present invention is to combine a sensor for detecting a parked vehicle in each parking space with an indicator disposed at a vehicle entry position to accurately confirm a parking situation in a parking lot to a driver outside the parking lot. It is an object of the present invention to provide a parking display device in a self-propelled parking lot that can be caused to run.

Means for Solving the Problems A configuration of the present invention for achieving the object has a sensor for detecting a parked vehicle in each parking space, and a fullness display unit and a parking display unit disposed at a vehicle approach position. A parking indicator operates in response to the detection signal of each sensor, and the full display unit operates in response to the detection signals of all the sensors, and the vehicle approaching at the vehicle approach position. The gist is to operate in response to the total number of vehicles in the parking lot corresponding to the difference between the number and the number of exiting vehicles detected by the disappearance of the detection signal of each sensor reaching the total number of parking spaces.

Operation According to the configuration of the present invention, each sensor can individually detect the parking space of the vehicle even when the vehicle is parked in any of the parking spaces.

The detection signal of the sensor that has captured the vehicle activates the corresponding parking indicator of the display arranged at the vehicle entry position, so that the driver of the vehicle will have to park in the parking lot before entering the parking lot. Can be confirmed. When all of the sensors output the detection signal, the fullness display unit operates in response to the detection signal, and the entry of the following vehicle can be prevented.

In addition, the fullness display unit operates based on the total number of vehicles in the parking lot corresponding to the difference between the number of vehicles entering the vehicle at the vehicle entry position and the number of exiting vehicles detected by the disappearance of the detection signal of each sensor, so that the parking space is displayed. Can be displayed immediately when the last vehicle that can secure the vehicle enters the hall, and it is possible to reliably avoid a situation in which a following vehicle that cannot be parked enters. Further, when the leaving vehicle leaves the parking space, it is possible to allow the following vehicle to enter without waiting for the vehicle to leave the parking lot.

Embodiments Hereinafter, embodiments will be described with reference to the drawings.

The parking display device in the self-propelled parking lot includes sensors Sa, Sb... Arranged corresponding to the parking spaces A, B,.
(See FIG. 1). However, the parking spaces A, B,... Are arranged on the first to fifth floors of the multi-story parking garage on the first to fifth floors of the parking floors 1F, 2F, respectively. The parking spaces A, B,. You can approach through 1R, 2R….

The sensors Sa, Sb ... are sensors for detecting vehicles disposed in the parking spaces of the parking spaces A, B ... and detect the vehicles C parked in the parking spaces A, B ... and output detection signals. Can be. A large number of sensors Sa, Sb... Are divided into blocks for each of the parking floors 1F, 2F (FIG. 2), and the detection signals of the sensors Sa, Sb. The signal is sent to the controller 20 as an independent system signal like a detection signal 2F1 from the 2F.

The display 10 displays the fullness display sections 11, 11 for displaying the full state of each of the parking floors 1F, 2F, and the arrangement of the passages 1R, 2R, and the parking spaces A, B for each of the parking floors 1F, 2F. Are displayed on the panel. In addition,
Each of the parking spaces A, B,... Of the full display units 11, 11,... And the parking display units 12, 12,.

The controller 20 includes sensors Sa, Sb,... Of the respective parking floors 1F, 2F,.
And the display 10. The controller 20 detects a detection signal from a sensor Sj installed in a specific parking space j (j = A, B...) Of a specific parking floor iF (i = 1, 2,...).
When iF 1 (i = 1, 2,...) is received, the parking display signal iF 2 is used to activate the position of the parking space j of the corresponding parking floor iF among the parking display sections 12, 12,.
(I = 1, 2,...) Are output. When the total number of the sensors Sa, Sb,... Of any one of the parking floors i outputs the detection signal iF1, the fullness display sections 11, 11,.
Among them, the fullness display signal iF3 (i = 1, 2,...) Is also output to activate the one corresponding to the parking floor iF.

The controller 20 receives a count signal 30a from a counter 30 that calculates the total number of vehicles in the parking lot. Controller 20
When the counting signal 30a reaches the total number of the parking spaces A, B,... In the parking lot, the full display units 1 on all the parking floors 1F, 2F,.
Fullness indication signals 1F3, 2F3 ... for 1, 11, ... are output.

The counter 30 is arranged at the vehicle entrance position EN together with the display 10 (FIG. 1), and performs an addition operation for the vehicle C entering and a subtraction operation for the vehicle C leaving. However, the counter 30 detects the entering vehicle C and directly counts the number of vehicles C, C..., That is, the number of entering vehicles, but the number of exits of the vehicles C, C. , Is counted indirectly by the exit signal 20a from the controller 20 (FIG. 2). The exit signal 20a is output from the sensors Sa, Sb ... regardless of whether or not the exiting vehicle C is still in the field.
Is a pulse signal that once outputs the detection signals 1F1, 2F1,... And then detects the disappearance of the detection signals 1F1, 2F1,. That is, the counter 30 counts the number of vehicles entering the vehicle at the vehicle entry position EN and the detection signals 1F 1, 2F of the sensors Sa, Sb,.
The controller 20 outputs a count signal 30a indicating the total number of vehicles in the parking lot corresponding to the difference from the number of exiting vehicles detected by the disappearance of 1, ..., and the controller 20 outputs the count signal 30a to the parking space A in the parking lot.
When the total number of B ... has been reached, the full-state indicators 11, 11 ... can be activated.

Therefore, the driver of the vehicles C, C... Can easily confirm the parking situation in the parking lot by looking at the display 10 before the vehicle entrance position EN. For example, the second
In the figure, the parking marks A, B,... Of the parking floors 1F, 3F on the first and third floors are all lit, and the parking marks 12a, 12a. You can go directly to the upper floor without entering the passage 1R. However, in this case, since the full display is displayed on the first and third floor full display sections 11 and 11, the driver does not need to check the parking display sections 12 and 12 and the first and third floor are full. Can also be determined.

Here, if the driver uses the parking space H on the parking floor 5F, the vehicle C is immediately counted by the counter 30 at the vehicle entrance position EN,
It is detected by the corresponding sensor Sh in the parking space H. The detection signal 5F 1 of the sensor Sh becomes a parking display signal 5F 2 via the controller 20, and the parking mark H of the parking mark H of the parking space H on the fifth floor parking floor 5F of the display 10
It is displayed as a, and the following vehicle is made to confirm that the parking space H is unavailable.

On the other hand, for example, empty parking spaces A, B,.
If the last two vehicles C, C enter the parking lot in a situation near fullness, such as the number of vehicles, when the vehicles C, C pass the position of the counter 30, the count signal 30a of the counter 30 will be parked. Because the total number of spaces A, B ... is equal to the total number of parking floors 1F, 2F ... of all floors without waiting for the last two vehicles C, C to park in the predetermined parking spaces A, B ... The display units 11, 11,... Are turned on, so that a following vehicle can be prevented from entering. Also, counter 30
Is based on the number of disappearances of the detection signals 1F1, 2F1... Of the sensors Sa, Sb,... Via the controller 20, so that the vehicle C, C,. Not
By turning off the fullness display sections 11, 11,..., The following vehicle can enter, and unnecessary waiting time can be eliminated.

In this embodiment, a parking display device in a self-propelled parking lot is applied to a multi-story parking garage including only a ground floor. This parking display device includes a basement parking floor and a single parking floor. It can be widely applied to parking lots and the like in which the inside parking situation cannot be checked from the outside. In any of these cases, the number of parking floors may be arbitrary. Note that the sensors Sa,
Sb ... are vehicles C, C parked in parking spaces A, B ...
.. May be of any type as long as it can be effectively detected, and may be attached to a dedicated pole or the like other than the bollard.

Also, the subtraction operation of the counter 30 for counting the total number of vehicles C, C...
In addition to the disappearance of 2F1,... May be detected by detecting vehicles C, C. Even if there are vehicles moving in the parking spaces A, B,... In the hall, there is no possibility that the full display units 11, 11,.
Further, the counter 30 is decremented after an appropriate time delay from the disappearance of the detection signals 1F 1, 2F 1..., And when there is a new output of the detection signals 1F 1, 2F 1.
30 may not be subtracted. However, in this case, the addition operation of the counter 30 is performed in order to identify whether the detection signals 1F 1, 2F 1... Are output by a vehicle newly entering the hall or output by a vehicle simply moving in the hall. It is preferable to take an appropriate interlock between them.

Effect of the Invention As described above, according to the present invention, by providing a sensor that detects a parked vehicle in each parking space, and a display unit having a full display unit and a parking display unit, the display unit can display an empty vehicle position Before entering the parking lot, the parking lot can be recognized by the parking lot user.Therefore, a following vehicle enters the full parking lot, or travels in the parking lot to search for an empty position. In addition to being able to avoid unnecessary confusion in the parking lot due to the collision, the fullness display section indicates a vehicle corresponding to the difference between the number of entering vehicles and the number of exiting vehicles detected by disappearance of the detection signal of each sensor. Since the operation is performed based on the total number, it is possible to reliably prevent entry of a following vehicle that cannot be parked, allow the exiting vehicle to leave the parking space, and at the same time allow the following vehicle to enter, so that the parking lot can be operated more smoothly. Has an excellent effect.
