Abstract

PURPOSE:To easily search an empty parking space by informing the space number of an empty parking space to a driver of an entering vehicle through a radio mounted on the vehicle or through the radio and a display. CONSTITUTION:The parking states of respective parking spaces are always monitored by a signal processing means based on signals outputted from respective sensors, and when only one parking space is empty, the space is selected. When plural parking spaces (P1, P5, P10) are empty, any one of them is selected and a signal 11 for converting the space number of the parking space into a voice is outputted from a voice composing output device 9. Entering vehicle detecting signals 6 generated from the device 9 and a photodetector 5 are inputted to a gate 12 connected between a voice output device 3 and the device 9. The detecting signal is also applied to a transmitter 14 and acts as an ON/ OFF signal for the transmitter. When an entering vehicle reaches an entrance and the vehicle is detected by an entering vehicle detecting means CS, the space number of a parking space to be parked at that time can be known through the radio mounted on his own vehicle.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention informs drivers of vacant parking lot numbers near the entrance of the parking lot when entering the parking lot, either by the car's radio or by the radio and a display. The present invention relates to a method for indicating a parking position.

[Conventional technology]

Conventionally, in parking lots of supermarkets and the like, visitors either search for an empty parking lot on their own or are guided to an empty parking lot according to instructions from a parking lot manager.

[Problem to be solved by the invention]

It is not easy to find an empty parking lot during busy times or in multi-story parking lots, and the method of assigning a manager has the drawback of requiring a lot of manpower.

This invention is intended to improve these problems.

[Means to solve the problem]

A sensor is installed in each parking lot to detect whether or not a car is parked, and an audio output device (the main components are speakers), a transmitter, and a transmitting antenna are installed at predetermined positions in the parking lot. In addition, means for detecting entering vehicles was installed to inform drivers of vehicles attempting to enter of the empty status of the parking lot at the time of entry, either by the military's own radio or by radio and display.

[For production]

As a result of processing the sensor signal by the signal processing means, when only one parking lot is vacant, the vacant parking lot is changed to -! If more than one parking lot is available, select one of them and notify the driver of the one lot by displaying '' or radio on your military's radio.

〔Example〕

Figure 1 schematically shows a parking lot, where P1 to Pn are parking bays, and S and Sn are sensors (for example, metal detectors) installed in each parking bay. It detects whether or not it is present and provides it to the signal processing means. C+,
Cz represents a car, 01 represents a car already parked in a parking lot, and C2 represents a car that is about to enter the parking lot at the entrance (1). (2) is the exit of the parking lot, and (3) is an audio output device installed at an appropriate position within the parking lot. C8 is an entering vehicle detection means, and is an entrance (
A light source (4) and a light receiver (5) are arranged opposite to each other with a light source (4) and a light receiver (5) placed in between. Therefore, if the car C2 blocks the light generated from the light source (4), it is determined that an entering car is at the entrance. In addition,
A detection signal (6) from the light receiver (5) is given to a gate circuit and a transmitter, which will be described later. Note that the transmitter and transmitting antenna are omitted in FIG. Figure 2(a) shows the relationship between the audio output device (3) and its related devices.
71 is a loudspeaker, (8) is an AMP, +91 is a voice synthesis output device, uu is a signal processing means connected to the plurality of sensors S1 to So, and 圓 is a transmitter that transmits the voice output from the voice output device.

C9 transmits weak FM radio waves using a transmitting antenna connected to the transmitter (14). α61 car receiving antenna, 07
) is the radio in the car. The parking status of each parking lot is constantly monitored by the signal processing means αα based on the signals from each sensor, and when only one parking lot is vacant as shown in Fig. 2(b), that vacant parking lot is .

In addition, as shown in Figure 2(c), there are multiple parking spaces (P□, P5
．． When the parking lot (Pto) is vacant, one of the parking sections is selected and the voice synthesis output device (9) outputs a signal (11J) for converting the number of the parking lot into voice. 3) and the voice synthesis output device (9), into which an entering vehicle detection signal (6) generated from the voice synthesis output device (9) and the light receiver (5) is input.

In addition, the detection signal is also given to the transmitter, and the transmitter is turned on.
, acts as an OFF signal.

Therefore, when a vehicle attempting to enter reaches the entrance and is detected by the entering vehicle detection means CS, the number of the available parking lot at that time can be known by the military's radio.

That is, the transmitter does not function when there is no vehicle attempting to enter, and the transmitter functions when there is a vehicle attempting to enter. Drivers who hear the number of available parking spaces on the radio can simply head straight to that space, without having to search around the parking lot.

In addition, if multiple compartments are vacant, selecting one is not only time consuming if the audio is output for all vacant compartments, but also the driver cannot bark at all of them. This is because it is actually sufficient to know one vacant partition.

FIG. 3 shows another embodiment of the present invention, in which the output of the speech synthesis output device (9) is displayed on a display device αJ. (131 is located near the entrance 11+.

In this way, it is possible to prevent overhearing from listening only to the radio.

Although the display device 9 needs to be placed at the entrance of the parking lot, it goes without saying that other signal processing means, transmitters, etc. may be placed at other appropriate locations.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to improve the conventional problems.
