Can be identified.

FIG. 2 is a conceptual diagram of the parking lot display system. The individual sensor units 1 installed on the front wall 22 of the parking space 20 and parking information obtained from these individual sensor units 1 are shown. Is displayed, and an overall parking status indicator 35 that collects parking information on each floor and displays the parking status of the entire parking lot.

FIGS. 1 and 3 show block diagrams of the parking lot display system. For example, the presence / absence of parking is detected by ultrasonic waves, and the presence / absence of parking information is transmitted from individual sensor units by radio waves. A system for receiving a radio wave indicating parking presence / absence information and displaying it on the parking status display board 10a on each floor will be described.

The individual sensor unit 1 comprises a detection sensor unit 2, an amplification circuit 3, an output circuit 4, and a transmission unit 5.

As shown in FIG. 3, when the car 30 is parked in the parking space 20 with the transmitting unit 2a for transmitting ultrasonic waves constantly toward the parking space 20 as shown in FIG. The receiving unit 2b receives the reflected ultrasonic waves reflected by the vehicle body 30a. The amplifying circuit 3 amplifies the signal obtained by the receiving section 2b.

Upon receiving the amplified signal, the output circuit 4 operates.

This output circuit 4 has a parking space number 23
And outputs a parking space number signal 6 corresponding to
For example, when 80 cars are stored in the entire parking lot, 80 kinds of parking space number signals 6 corresponding to the parking space numbers 23 are required.

In order to obtain 80 kinds of parking space number signals 6, for example, different 80s are used by combining frequencies and amplitudes.
The types of waveforms are set in advance, and these 80 types of waveforms are assigned to each parking space number, and set in the output circuit 4 of the individual sensor unit 1. For example, in the 2-1 parking space, the 21st parking space number signal 6-21
Is output, the first individual sensor unit 1 on the second floor
This is set in the output circuit 4 of −21.

The transmitting unit 5 transmits the parking space number signal 6-21 output from the output circuit 4, for example, as a radio wave, but there are 20 parking spaces on the same floor (2F). When the parking space is “full”, 20 different types of radio waves (signals by parking space number) are transmitted, and the receiving unit 12 of each floor parking status display 10 transmits 20 different types of radio waves with different waveforms. Are received at the same time. For this reason, the parking space number signal 6 is mixed, and the parking space number signal cannot be correctly processed.

In order to solve this situation, the transmitter 5 of each individual sensor unit 1 is provided with a transmitter (not shown) for transmitting the parking space numbers in the order of the parking space numbers. In the case of 2 and 2-5, the parking space number signal 6-2 is transmitted from the transmitting unit of the parking space of 2-1.
After transmitting 1, the parking space number signal 6-22 of 2-2 is transmitted at a short interval. Next, after an interval of two parking spaces, a parking space number signal 6-25 of 2-5 is transmitted.

The radio wave transmitted from the transmission unit 5 of the individual sensor unit 1 is received by the reception unit 12 of each floor parking status display 10, and the reception signal is amplified by the amplification circuit 13.

The parking space number signal 6 amplified by the amplification circuit 13 is determined by the determination circuit 14 to be the corresponding parking space number, and the display circuit 16 for the corresponding parking space number is determined.
To turn off the lamp of the corresponding parking space number on each floor parking status display board 10a.

The lamp lighting circuit (not shown) holds the lamp in a light-off state for a predetermined time when a lamp-off signal is received, and when the lamp-light-off signal is not received after a predetermined time has elapsed, The display circuit 16 turns on the lamp.

When the vehicle 30 exits from the parking space 20, the reflected wave is not received by the receiving section 2b of the detection sensor section 2 of the individual sensor unit 1, so that the transmitting section 5 of the individual sensor unit 1 receives the reflected electric wave. The radio wave stops transmitting. For this reason, the lighting circuit of the display lamp does not receive the light-off signal, and as a result, the lighting circuit is activated, the display lamp is turned on, and the character “empty” on the lamp cover 31 is displayed brightly.

FIG. 4 is a block diagram of a parking lot display system related to each floor parking status indicator and the whole parking status indicator. The parking space number signal 6 received by the receiver 12 of the parking status indicator 10 for each floor is shown. Is amplified by the amplifier circuit 13,
The data is sent directly to the transmission unit 15 without passing through the interpretation circuit 14.

From the transmitter 15 of the parking status display 10 on each floor, a total of 80 types of parking space number signals are transmitted from each of the 20 types of parking space number signals. When these signals are received at the same time, the parking space number signal is mixed, and the parking space number signal cannot be correctly processed.

Therefore, the transmitting unit 15 of each floor parking status display 10 is provided with a transmitting device (not shown) for transmitting the parking space number signals in the order of the parking space numbers so that the parking space number signals are not redundantly transmitted.

The electric wave (signal for each parking space number) transmitted from the transmitter 15 of the parking status display 10 on each floor is received by the receiver 37 of the overall parking status display 35, and the parking space number signal 6 is amplified by the amplifier circuit 38. The reading circuit 39 determines the predetermined parking space number, and the display circuit 40 turns off the lamp of the predetermined parking space number.

The lamp extinguishing circuit (not shown) keeps the lamp turned off for a predetermined time when a lamp extinguishing signal is received, and turns on the lamp when no lamp extinguishing signal is received after a predetermined time has passed. When a car comes out of the parking space, the display lamp is turned on to display "empty" characters.

The detection sensor section of the individual sensor unit has been described above using ultrasonic waves. However, when both wheels of the vehicle enter the parking space, the detection switch is activated.
With a detection switch through which the parking detection current flows,
Glass fiber is installed in the detection switch, amplification circuit, output circuit, and transmission section, and electrical signals are transmitted in this glass fiber, and glass fiber is placed between the individual sensor unit and the parking status display board on each floor and the entire parking status display board. May be installed to transmit an electric signal within the glass fiber.
