Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a three-dimensional parking lot or the like, and more specifically, a nonstandard vehicle whose physical size does not fit into the parking space of the parking lot. The present invention relates to a non-standard vehicle detection device for a parking lot, which is capable of restricting the entry of the vehicle or guiding it to another parking facility or the like by checking in advance.

[0002]

2. Description of the Related Art In a conventional three-dimensional parking lot, two sensors S ₁ and S ₂ for detecting the length of a vehicle are provided at intervals on an entrance passage connected to the parking lot as shown in FIG. , This 2
It is determined whether the length of the vehicle is longer or shorter than the distance between the _two sensors S ₁ and S ₂ , and if the vehicle is a short vehicle T _{1 as} in case A, the storage is permitted within the standard and as in case B. In the case of a long vehicle T ₂ , the storage was restricted because it was out of specification.

Further, in the conventional three-dimensional parking lot, a height detecting sensor D for detecting the height of the vehicle is provided on the upper side of the above-mentioned storage passage as shown in FIG. _If the vehicle height of _{1 is} a height that cannot be detected by the sensor D, the warehousing is permitted within the standard, and the vehicle T ₂ as in case E
If the vehicle height is a height that can be detected by the sensor D, the warehousing is controlled as a vehicle that is out of the standard.

[0004]

However, when the length of the vehicle is detected by using the _two sensors S ₁ and S ₂ shown in FIG. 8, a plurality of vehicles are used as in case C in FIG. The first vehicle (1st
If the following second vehicle is detected by the outer second sensor S ₂ before the vehicle 1) passes the inner first sensor S ₁ , both S ₁ and S ₂ are turned on and the case B described above is applied. As a result, the first vehicle is erroneously judged to have a length outside the standard even though it is actually within the standard, and there is a storage restriction such as a parking ticket not being issued or the gate not opening. There was a problem.

Similarly, when the vehicle height is detected by the height detection sensor D shown in FIG. 9, a succeeding vehicle (second vehicle) which is continuously parked without a space like the case F shown in FIG. If the vehicle height of (T ₂ ) is high and the height detection sensor D detects this, the situation is the same as in case E described above, and as a result, the height is within the standard, but the first There is a problem that the vehicle height of the vehicle T ₁ is erroneously determined to be out of the standard, and the first vehicle T ₁ is subject to the storage restriction.

Regarding the erroneous determination of the height, as shown in the case G of FIG. 9, the height detection sensor D and the second sensor S ₂
If the second sensor S ₂ is not detected (OFF), that is, when the second vehicle T ₂ has completed passing, the output of the NG is determined. One vehicle T ₁ can be loaded without being affected by the following second vehicle T ₂ , but the second vehicle T ₂ is moved in the direction of the arrow shown in the figure after the detection of the second sensor S _2. Even when the vehicle is moved back, the NG output is determined as the passage has been completed, so that the same result as in case F occurs and there is a problem that the first vehicle T ₁ is erroneously determined to be out of the standard. It was

Therefore, the technical problem of the present invention is that, when vehicles are continuously loaded, the length and height of the leading vehicle are within the standard without being influenced by the following vehicles. It is to judge correctly whether it is outside.

[0008]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows. In a parking lot management device configured so that when a sensor detects an incoming vehicle, the vehicle is put in the parking lot and the vehicle is put in the parking lot,

(1) A first vehicle sensor and a second vehicle sensor for determining the length of a vehicle are provided in the storage passage with a space provided therebetween.
An in-vehicle detection sensor for determining the presence or absence of a vehicle is provided between these two sensors, and if all of these sensors detect the vehicle, it is determined that the vehicle is out of specification, and all sensors are Even if the vehicle is detecting the vehicle, if the detection states of the second vehicle sensor and the vehicle detection sensor on the entrance side of the passage are respectively in the order of ON → OFF → ON, it means that the vehicle is within the standard. If it is determined that the vehicle is within the standard, an OK signal is output, and if the vehicle is out of the standard, an NG signal is output.

(2) A height detecting sensor is provided above the second vehicle sensor provided on the entrance side of the passage, and when both of these sensors detect the vehicle, it is determined that the vehicle is out of the standard and It is determined that the vehicle is a non-standard vehicle when the leading vehicle passes the in-vehicle detection sensor and the vehicle passes the second vehicle sensor, and after this determination is made, the NG signal is output. Be configured to be output. Here, the warehousing process means a parking ticket issuing process by a parking ticket issuing machine provided at the entrance of the parking lot, an entrance gate opening process, and the like.

[0011]

The above means operates as follows. Above (1)
According to the above-mentioned means, even when a plurality of vehicles come in continuously and all three sensors provided on the passage detect the vehicle and turn on, an intermediate vehicle detection sensor or an entrance is provided. One of the second vehicle sensors on the side turns on vehicle detection →
In the case of OFF → ON, one vehicle is not detected by all the sensors because there is an interval between the vehicles, but two vehicles before and after are detected by these three sensors. Therefore, even if the vehicles come in continuously, it is accurately judged whether or not the length is within the standard one by one, and either OK or NG is determined. It is possible to output the signal of.

According to the means described in the above (2), even when the vehicle is continuously loaded and it is determined that the height of the following vehicle is out of the standard range, this determination is made by the leading vehicle. Since it is not determined that the vehicle passing through the intermediate vehicle detection sensor and the vehicle following does not pass the second vehicle sensor, it is possible to solve the problem that the vehicle height of the leading vehicle is erroneously determined by the vehicle following.
Even if the following vehicle backs up while the leading vehicle is at the position of the presence detection sensor, it does not affect the determination of the leading vehicle. If you move back, the decision confirmation will be issued, but there is no vehicle affected by it, and the confirmation permission will be issued again by the next vehicle to be stored. It is always possible to make a correct decision. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.

When it is determined that the parking ticket is out of the standard, an NG signal is output to display on the display 9 that the vehicle cannot be stored, a display for guiding to another parking facility, and the like, and the parking ticket issuing machine 2 Various kinds of warehousing prohibition processing for stopping the issuance of a parking ticket are performed, but instead of the above-mentioned display device 9, a voice generator is used to inform whether or not warehousing is possible, or both the display device 9 and the voice generator are provided. In some cases, it may inform you whether or not the goods can be stored.

Next, the procedure for determining whether the vehicle is within the standard according to the present invention will be described with reference to the flow charts shown in FIGS. 3, 5 and 6. FIG. 3 is a flowchart for explaining the processing procedure for determining the length of the vehicle. In the first step S1, the first incoming vehicle is the first vehicle inward.
It is determined whether or not the vehicle sensor C detects, and the detection (O
N), the process proceeds to the next step S2, this time it is determined whether or not the second vehicle sensor A on the outside has detected the vehicle, and if not (see Case 1 of FIG. 4). It is determined that the vehicle is within the standard, the OK flag is set in step S7, and then the process proceeds to step S8 where the OK signal is output. However, when the second vehicle sensor A is turned on, the process proceeds to the next step S3.

In step S3, an intermediate vehicle detection sensor B
Is detected (ON / OFF), and if it is OFF (see Case 2 in FIG. 4), it is determined that the vehicle is within the standard, the process proceeds to steps S7 and S8, and an OK signal is output. If it is ON, the process proceeds to the next step S4.

In step S4, it is determined whether or not the detection states of the in-vehicle detection sensor B are in the order of ON → OFF → ON, that is, after the first vehicle T ₁ passes (ON → OFF), the second vehicle again. It is determined by T ₂ whether or not the vehicle is turned on, and if YES (see case 3 in FIG. 4), it is determined that the vehicle is within the standard, and the process proceeds to steps S7 and S8 to output the OK signal. , NO, that is, when OFF is not detected, the process proceeds to the next step S5.

At step S5, it is determined whether or not the detection states of the second vehicle sensor A are ON → OFF → ON, that is, after the first vehicle T ₁ has passed (ON → OFF), the second vehicle is again detected. It is determined by T ₂ whether or not the vehicle is turned on, and if YES (see case 4 in FIG. 4), it is determined that the vehicle is within the standard, and the process proceeds to steps S7 and S8 to output the OK signal. However, in the case of NO (see case 5 in FIG. 4), it is determined that the vehicle is out of the standard, and step S
In step 6, the NG flag is set, and then in step S8, the NG signal is output.

Next, FIG. 5 is a flow chart for explaining the processing procedure for judging the height of the vehicle. In the first step S10, the NG flag is reset. Next, in step S11, it is determined whether or not the second vehicle sensor A has detected a vehicle entering the vehicle (ON / OFF). If YES, the process proceeds to step S12, in which the height detection sensor D detects the vehicle. It is determined whether or not it is detected, and if it is detected (YE
S), the process proceeds to step S13, the NG flag is set, and the process proceeds to the next step S14, but if it is not detected (N
O) directly proceeds to step S14.

In step S14, the vehicle (second vehicle T _{2 in} FIG. 7) determined whether or not the second vehicle sensor A is turned off, that is, the height is out of the standard is the second vehicle sensor A. It is determined whether or not the vehicle has passed, and if the vehicle has detected the passage, the process proceeds to the next step S15, and if the vehicle has not passed, the process returns to step S12 and repeats the processing.

In step S15, whether or not the confirmation permission has been issued by the confirmation permission processing shown in FIG. 6, that is,
It is determined whether or not the confirmation permission flag is set, and if YES, the process proceeds to step S16 for the first time.
The following second vehicle T ₂ shown in (1) is judged to have a high vehicle height and is out of the standard, and an NG signal is output. If NO, the process returns to step S12 and the process is repeated, and
When the height detection sensor D does not detect the vehicle in step S12, that is, when it is determined that the vehicle height is within the standard,
After step S14 and step S15, step S16
Outputs an OK signal.

FIG. 6 is a flowchart for explaining the processing procedure for determining the confirmation permission described in step S15 described above. In the first step S20, it is determined whether or not the second vehicle sensor A has detected a vehicle. If it is not detected, the procedure goes to step S23 to reset the confirmation permission, and if it is detected, the procedure goes to next step S21 to determine whether or not the vehicle detection sensor B detects the vehicle, that is, the previous It is determined whether or not one vehicle T ₁ has passed the in-vehicle detection sensor B, and if it is determined that it has passed, step S22.
Then, the confirmation permission flag is set, and the determination of the height detection of the second vehicle T ₂ by the height detection sensor D can be confirmed, but the presence detection sensor B detects the first vehicle T _1. When the vehicle is present, the flag for determining the vehicle height detection of the second vehicle T ₂ is not set, and therefore, the preceding vehicle (the first vehicle T ₁ )
It is possible to solve the problem that the vehicle height determination is erroneously determined by the following vehicle (second vehicle T ₂ ).
