DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for managing parking lot information of an automobile in which each parking lot and a monitoring center are connected by a public line, and parking lot information is collected from each parking lot and centrally managed by the monitoring center. About.

[0002]

2. Description of the Related Art Conventionally, as a parking lot guidance system for a car, a device for collecting congestion information of a parking lot, a display plate for displaying a parking lot congestion state near an installation point installed on the side of a road, and collecting the collected data. It is well known that the apparatus is configured by a device that totals and transmits necessary vacancy information to each display board.

According to this parking lot guidance system, the display board beside the road is connected to the display board via a cable from the central control device. For this reason, it is a large-scale system because it is necessary to lay a long cable in the area where a parking lot and a display board are needed for collecting and sending information.
The project was led by local governments and government offices, and was difficult to implement in private companies. In addition, it is difficult to install the display board evenly in the city from the viewpoint of the installation place and the cost of the display board, so that the display board is installed only at a main point.

[0004] For these reasons, information transmission is performed using a public line without laying a cable for information transmission.
Automobile parking guidance systems have been developed. In such a car parking guide system, a public line is used between the central monitoring center and each parking lot as shown in FIG.

[0005]

The central monitoring center 30 shown in FIG. 4 has external parking lots 10A, 10B, 10C.
And a communication device 8 connected to the public line. The timer 20 drives the data collection device 7 at predetermined time intervals to collect parking lot information from each parking lot.

[0006] However, since this technique is performed periodically at a predetermined time interval using a public line, data is collected even in a state where the number of parked vehicles is not changed during off periods when the number of parked vehicles is small, and communication costs are reduced. It becomes expensive and running cost becomes a problem.

[0007] In view of the above circumstances, an object of the present invention is to provide a method of managing parking lot information of a car which determines a data collection frequency in consideration of off-peak periods and congestion periods so that communication costs do not increase. I do. It is another object of the present invention to provide a method of managing parking information of a car, which determines a data collection frequency in consideration of past parking information and events, road conditions, and the like of the corresponding day.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a method for managing parking lot information of an automobile, and the first invention connects each parking lot and a monitoring center by a public line, and connects each parking lot to a monitoring center. In the method for managing parking information of a car, which collects parking information and centrally manages the information at the monitoring center, the frequency of data collection during a parking season is set lower than the frequency of data collection during a congestion period. .

The off-peak period and the congestion period of the parking lot may be different in each parking lot. That is, in the parking lot near the train station, when the train commuters use, the morning and evening commuting hours are crowded, and when it is close to the event venue, large retail stores, etc.,
The congestion period starts at the opening and opening hours. Therefore,
The communication cost can be reduced by lowering the data collection frequency during the off-peak period than the data collection frequency set during the congestion period.

It is also an effective means of the first invention to determine the frequency of collecting the data in consideration of past parking lot information and additional information such as event information and road information on the corresponding day. When there is an event, the parking lot is congested, and when the road is congested, the time to arrive at the parking lot is delayed, and the congested time zone shifts later. Therefore, by considering these pieces of information, the communication cost can be reduced by determining the frequency of data collection.

Further, the second invention connects a parking lot to a monitoring center via a public line, collects parking lot information from each parking lot, and centrally manages the parking lot information in the monitoring center. , The data collection timing of the parking lot is set to a timing that is achieved earlier in time either of the predetermined number of parked vehicles or the regular time interval.

[0012] In some cases, the frequency of data collection in the parking lot does not change the number of parked vehicles at regular time intervals. Therefore, by adding a condition for each predetermined number, data is collected from the predetermined number or the time interval, whichever comes earlier in time. In this case, it is possible to set each regular time interval to a non-working period and to cope with a predetermined number of vehicles during a congestion period.

It is also an effective means of the second invention to determine the predetermined number or the regular time interval in consideration of past parking lot information and additional information such as event information and road information on the corresponding day. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention unless otherwise specified, and are merely illustrative examples. Only.

FIG. 1 is a block diagram showing a first embodiment of the present invention, FIG. 2 is a block diagram showing a second embodiment of the present invention, and FIG. 3 shows a third embodiment of the present invention. FIG. 4 is a block diagram showing a conventional car parking lot information management method.

In the first embodiment shown in FIG. 1, a central monitoring center 1A for centrally managing information on each parking lot and each parking lot 10
A, 10B, 10C,...
Is configured to be accessible. Here the public line 21
Means a wired telephone network that can be communicated with a home telephone, but it goes without saying that a portable telephone may be used to connect to the wired communication network, or a personal computer communication network may be used. Good.

The central monitoring center 1A is provided with a collection interval setting device 3 and a start timer setting device 5. The collection interval setting device 3 uses the operation panel 2 to store data of each parking lot as described in a table 4. The collection time zone and interval can be set. Further, a start timer 6 is provided, the start timer setting device 5 is set under the conditions of the time zone and the interval of the table 4, and the start timer 6 is started under the above conditions.

A data collection device 7 driven by the start timer 6 to collect each parking lot information, a parking lot information database 9 for storing the collected parking lot information, and a signal of the data collection device 7 A communication device 8 that transmits to the parking lot 10 and obtains each parking lot information to send to the data collection device 7 is provided.

The first embodiment configured as described above has the following features.
Since the time zone and data collection interval can be set for each parking lot, the frequency of data collection during the congestion period of the parking lot is high, and the frequency of data collection during the off-peak period of the parking lot is lower than the frequency of data collection during the congestion period. In addition to the setting, the frequency can be arbitrarily changed on the central monitoring center side.

Therefore, in a parking lot near a train station, when commuters use the train, the commuting hours in the morning and evening are congested. For example, the congestion period starts, so that the data collection frequency can be lower in the off-period than the data collection frequency set in the congestion period for each parking lot, so that the communication cost can be reduced.

FIG. 2 is a block diagram showing a second embodiment of the present invention. The same members as those in FIG. 1 are denoted by the same reference numerals. The difference from the first embodiment is that FIG. 1 uses the collection interval setting device 3 to set the data collection frequency, whereas the present embodiment uses external information such as events and road information. From the information and past parking lot information, a congestion prediction is performed using a congestion prediction calculation device, and a data collection frequency is set.

The central monitoring center 1B shown in FIG. 2 has a database 11 for storing the additional information, the parking information from the parking information database 9, and the congestion prediction of the future parking lot from the additional information of the database 11. Is calculated.

Since the second embodiment is configured as described above, the frequency of collecting the data is determined in consideration of past parking lot information and additional information such as event information and road information on the corresponding day. The parking lot is congested when there is an event, and when the road is congested, the time to arrive at the parking lot can be delayed and the congested time zone can be shifted later, By considering the information, the frequency of data collection during the congestion period and the off-peak period is determined, so that useless data collection during the off-period can be suppressed, and an increase in communication cost can be suppressed.

FIG. 3 is a block diagram showing a method for setting the frequency of data collection at each parking lot according to a third embodiment of the present invention. In the first and second embodiments described above, the frequency of data collection in each parking lot is set in the central monitoring center, whereas in the present embodiment, the frequency of data collection in each parking lot can be set. Is different from the first embodiment.

In FIG. 3, in each parking lot 10, the parking number counter 13, the notification change number setting device 14, and the parking number counter 13 based on the number set by the notification change number setting device 14. A parking number change monitoring device 15 that generates an output when the number of vehicles exceeds the set number;
A time interval timer 19 for sending output every predetermined time;
A notification activation device 16 for obtaining the number of parking number counters 13 from the output signal of the parking number change monitoring device 15 or the time interval timer 19 is provided.

When the notification activation device 16 obtains the number of parked vehicles from the parking number counter 13, the notification activation device 16 outputs the number of parked vehicles together with the activation signal, and the activation signal is transmitted to the parking number change monitoring device 15 and the regular time interval. A reset signal is given to the timer 19 to make the change value of the number of parked vehicles zero and the timer value of the regular interval timer to zero.

In each parking lot, a data notification device 17 and a communication device 18 for transmitting parking lot data to the central monitoring centers 1A and 1B are arranged, and when the parking number is received together with an activation signal from the notification activation device 16, Data notification device 17
Sends the data to the communication device 18 and the communication device 18
Transmits the parking lot data to the central monitoring centers 1A and 1B.

In the third embodiment, when the set number is set to n by the notification change number setting device 14, the parking number change monitoring device 15 outputs an output signal when the value of the parking number counter 13 exceeds n. The notification activation device 16 receives the numerical value of the parking number counter 13 and transmits the value to the central monitoring centers 1A and 1B via the data notification device 17 and the communication device 18. Is sent to the parking number change monitoring device 15 to reset the count number of the parking number counter 13 to zero.

An activation signal from the notification activation device 16 resets the count of the parking number counter 13 and resets the time interval timer 19, and when the timer counts for a predetermined time, outputs an output signal to the notification activation device. 1
6, the notification activation device 16 receives the numerical value of the parking number counter 13 and transmits the value to the central monitoring centers 1A and 1B via the data notification device 17 and the communication device 18.
The activation signal from the notification activation device 16 is sent to the parking number change monitoring device 15 to reset the count number of the parking number counter 13 to zero and reset the time interval timer 19.

As described above, the notification activation device 16 is either the parking number changing device 15 or the time interval timer 19, which is satisfied in time either at the predetermined number or at the time interval.
It is driven by either of these signals.

Therefore, the frequency of data collection in the parking lot can be adjusted by adding a condition for each predetermined number of vehicles even if the number of parking spaces does not change at regular time intervals due to the silencer.
Since the data is collected at the earlier one of the predetermined number and the regular time interval, it is possible to cope with the congestion period.

In the third embodiment, the number of notification change units can be arbitrarily set by the notification change unit setting device 14 or the time interval at a predetermined time interval by the time interval timer 19. By accessing the indicated congestion prediction operation device 22 and using the data of the congestion prediction operation device 22, the set number of the notification change number setting device 14 or the predetermined time interval of the time interval timer 19 may be determined.

[0033]

As described above in detail, according to the present invention, the frequency of data collection during the off-period of the parking lot is made lower than the frequency of data collection during the congestion-period, so that extra data is collected during the off-period. And communication costs can be reduced.

By setting the data collection time of the parking lot to a predetermined number of parked vehicles or a fixed time interval, whichever is earlier achieved in terms of time, even if a congestion period suddenly appears, the predetermined number of vehicles can be collected. Since data is collected every time you achieve it,
The frequency of data collection can be automatically increased.
