Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for detecting whether or not a person is present on the entrance / exit floor of a multi-level parking device.

[0002]

2. Description of the Related Art In a multi-story parking system equipped with a storage mechanism such as an elevator and a gondola, a driver puts the vehicle on the floor for loading and unloading, gets off the vehicle and exits the parking system, and then drives the storage mechanism to store the vehicle. To do. When driving the storage mechanism, it is dangerous if the driver does not leave, so it is necessary to confirm whether or not the driver has left the parking device. Therefore, conventionally, as shown in FIG. 4, two sets of light beams that form a horizontal beam B in a direction substantially perpendicular to the traveling direction of the vehicle 4 are provided near the entrance 3 of the floor 2 of the parking lot 1. A detection device has been used in which the cut-off type detectors PH1 and PH2 are arranged apart from each other by a predetermined distance in the traveling direction of the vehicle. In this detector, as shown in FIG.
When the first and the second PH2 are operated by blocking the beam B at the same time, it is detected as the passage of the vehicle 4, and the detectors PH1, PH2 are detected.
Was designed to detect beam B as being passed by the driver when the beam B was cut off and operated at different times. That is, this is based on the premise that only the vehicle 4 and the driver driving the vehicle 4 enter the loading / unloading floor 2, and after detecting the entry of the vehicle 4 by the simultaneous operation of the detectors PH1 and PH2, the detector PH1 is detected. , If PH2 operates sequentially, it is considered that the driver has exited, it is judged to be safe, and the storage mechanism is driven.

[0003]

The warning is given on the notices such that only one driver can enter the vehicle when the vehicle is loaded into the loading / unloading floor of the parking device. However, in reality, the warning is overlooked, or Ignoring it, passengers may enter the loading / unloading floor together. In such a case, with the conventional detection device, it is not possible to confirm the exit of all the people who entered, and when the first one exits, the storage mechanism may be driven, and safety cannot be ensured.

Further, when the driver leaves the vehicle with a large baggage after getting in the vehicle, the two sets of detectors may operate at the same time. In this case, since it is not detected as a person leaving, the storage mechanism does not start. Further, if the driver carries out loading and unloading of luggage in the trunk after boarding, or returns to pick up forgotten items after exiting, the driver may be misidentified and treated as a failure.

Moreover, a predetermined distance must be ensured between the two sets of detectors, and a large installation area is required. This invention solves the above-mentioned problem in the human detection device of the multilevel parking device, which can reliably detect the presence or absence of a person in the loading / unloading floor, and improves the safety of the multilevel parking device. An object of the present invention is to provide a person detection device in a multi-level parking device that can reduce the installation area.

SUMMARY OF THE INVENTION According to the present invention, a light beam interception type detector for forming a plurality of beams (light beams) on a loading / unloading floor of a multi-level parking device on a boarding / alighting deck in parallel with a traveling direction of a vehicle, The above problem is solved by arranging a moving body detector capable of detecting the presence of a moving body in the delivery floor.

[0007]

[Function] When the driver puts the vehicle on the loading / unloading floor, the moving body detector is turned on and the entry is detected. When the driver stops the vehicle and gets off on the boarding / alighting deck, the beam on the boarding / alighting deck is blocked, and the light-blocking detector is turned on to detect the getting-off of the driver. When the driver leaves the boarding / alighting deck, the light blocking detector is turned off, but the moving body detector is turned on while the driver is in the loading / unloading floor, and the storage mechanism is not driven. When the driver leaves the loading / unloading floor, the moving body detector also turns off and the storage mechanism is driven. If a passenger enters the loading / unloading floor with the driver, the passenger is also detected,
There is no fear that the storage mechanism will be driven until everyone exits the storage floor. Further, even if the driver has a large baggage, misidentification does not occur, so that the storage mechanism can operate normally.

Is arranged at a position where a moving body can be detected over the entire loading / unloading floor 2.

The light beam interception type detectors PH3 and PH4 are equipped with photocells and operate when any one of the plurality of beams B formed on the boarding / alighting deck 11 is shielded. In addition,
The light blocking detectors PH3 and PH4 may use infrared rays other than visible light, for example. The moving body detectors SE1 and SE2 are infrared sensors that detect a moving heat source, and can detect the presence of a person somewhere by monitoring the entire area inside the loading / unloading floor 2. It does not work with small animals such as mice.

When the driver puts the vehicle 4 on the entrance / exit floor 2 through the entrance 3, the moving body detectors SE1 and SE2 are turned on to detect the entrance. When the driver stops the vehicle 4 on the pallet 5 and dismounts on the boarding / alighting deck 11, the beam B on the boarding / alighting deck 11 is blocked, and the beam blocking detector PH
Any one of 3 and PH4 is turned on to detect the exit of the driver. When the driver leaves the boarding / alighting deck 11, the light blocking detectors PH3 and PH4 are turned off, but the moving body detectors SE1 and SE2 are turned on, and the elevator 7 is not driven. When the driver leaves the loading / unloading floor 2, the moving body detectors SE1 and SE2 are turned off and the elevator 7 can be driven.

When a passenger enters the loading / unloading floor 2, the moving body detectors SE1 and S until all the passengers leave the floor.
E2 is not turned off and the elevator 7 is not driven.
When there is a person in the loading / unloading floor 2, even if another user accidentally tries to drive the elevator 7, the motion detector SE1,
Since SE2 is ON, the elevator 7 does not start and a caution display is displayed to inform that there is a person inside.

The driver takes out a large baggage,
Even when loading and unloading luggage in the trunk, the motion detectors SE1 and SE2 are ON while the person is in the loading / unloading floor 2.
Therefore, when all the people leave the loading / unloading floor 2, the moving body detectors SE1 and SE2 are turned off, so that the presence or absence of a person is not mistakenly recognized. After the operation of the elevator 7 is started, when the elevator platform 10 is inside the loading / unloading floor 2, the elevator platform 10 serves as a moving body and SE
1 and SE2, the detection signal is ignored, and the beam interception type detectors PH3 and PH
When any one of 4 operates, the elevator performs an emergency stop.

After the elevating table 10 has moved above the ceiling 12 of the loading / unloading floor 2, an alarm is issued by the operation of the beam interception type detectors PH3 and PH4.
