Parking information is collected from each parking lot.
[0006]
However, because this technology is regularly performed at regular time intervals using public lines, data is collected even in the quiet period when the number of parked cars is low and the number of cars remains unchanged, resulting in high communication costs. The running cost becomes a problem.
[0007]
In view of the above circumstances, an object of the present invention is to provide an automobile parking lot information management method that determines a data collection frequency in consideration of a quiet period and a congested period so that communication costs are not high.
Another object of the present invention is to provide an automobile parking lot information management method that determines data collection frequency in consideration of past parking lot information, events on the day, road conditions, and the like.
[0008]
[Means for Solving the Problems]
The present invention relates to a parking lot information management method for automobiles, and the first invention relates to the monitoring by collecting parking lot information from each parking lot by connecting each parking lot and a monitoring center via a public line. In the car parking information management method centrally managed in the center, the time zone and the collection interval for collecting parking information for each parking lot are set using the operation panel on the monitoring center side . The time zone and the collection interval are set so that the frequency of data collection is lower than the frequency of data collection in the busy period, and the monitoring center collects parking lot information from each parking lot based on the setting conditions. Features.
[0009]
The parking season may be different in each parking lot during the off season and the busy season. In other words, in parking lots near train stations, commuting hours are crowded in the morning and evening when train commuters use, and when it is close to event venues and large stores, etc., it is congested according to the opening and opening times. Starts. Therefore, the communication cost can be reduced by lowering the data collection frequency in the quiet period than the data collection frequency set in the busy period.
[0010]
In addition, the monitoring center predicts parking lot congestion using a congestion prediction calculation device from past parking lot congestion information, event information on the day of the event , and additional information on road congestion information. Determining the collection frequency of the car park information is also an effective means of the first invention. 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 time zone during which the congestion occurs is shifted later. Therefore, by considering these pieces of information, the communication cost can be kept low by determining the frequency of data collection.
[0011]
Further, the present second invention, connects the parking lot and a monitoring center in the public line, the parking lot information management method of a vehicle to collect the parking lot information to centralize the monitoring center from the parking lot, each The parking lot sets the time when the parking lot data is transmitted to the monitoring center at a time when the predetermined number of parking lots or a regular interval is reached first, and each parking lot is based on the setting condition. The parking lot information is transmitted to the monitoring center .
[0012]
The number of parking lots may not change at regular intervals for the frequency of data collection in the parking lot. Therefore, by adding a condition for each predetermined number of units, data is collected by either the predetermined number or the regular interval, whichever comes first in time. In this case, every fixed time interval can be set to a quiet period, and the crowded period can be dealt with every predetermined number.
[0013]
Further, it predicts the congestion of the parking lot using the congestion prediction calculation device from the past parking lot congestion information, the event information on the day of the event , and the additional information of the road congestion information. It is also an effective means of the second invention to determine the fixed time interval.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, exemplary embodiments of the present invention will 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.

In the first embodiment shown in FIG. 1, the central monitoring center 1A that centrally manages information on each parking lot and the parking lots 10A, 10B, 10C,... Yes. Here, the public line 21 means a wired telephone network that can be communicated by a household telephone, but it is of course possible to connect to the wired communication network using a portable telephone, and personal computer communication. A network may be used.
[0017]
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 record data collection time zones of each parking lot as described in the table 4. And the interval can be set.
Also, a start timer 6 is provided, and the start timer setting device 5 is set under the conditions of the time zone and interval of the table 4, and the start timer 6 is started under the above conditions.
[0018]
In addition, the data collection device 7 that is driven by the activation timer 6 and collects each parking lot information, the parking lot information database 9 that stores the collected parking lot information, and the signal of the data collection device 7 are sent to each parking lot 10. The communication device 8 is arranged to transmit to the data collection device 7 and obtain each parking lot information.
[0019]
In the first embodiment configured as described above, since the time zone and the data collection interval can be set for each parking lot, the data collection frequency of the parking lot is high, and the data collection in the parking lot is in a quiet period. Can be set lower than the frequency of data collection in the congested period, and the frequency can be arbitrarily changed on the central monitoring center side.
[0020]
Therefore, in parking lots near train stations, commuting hours are crowded in the morning and evening when used by train commuters, and when it is close to event venues and large stores, etc., it is congested according to the opening and opening times. Thus, for each parking lot, it is possible to lower the data collection frequency in the off-season than the data collection frequency set in the congested period, thereby reducing the communication cost.
[0021]
FIG. 2 is a block diagram showing a second embodiment relating to the present invention, and the same members as those in FIG. The difference from the first embodiment is that the data collection frequency is set by using the collection interval setting device 3 in FIG. 1, but this embodiment does not add additional information such as events and road information to the outside. The data collection frequency is set by performing congestion prediction using the congestion prediction calculation device from these information and past parking lot information.
[0022]
The central monitoring center 1B in FIG. 2 calculates the future congestion prediction of the parking lot from the database 11 storing the additional information, the parking lot information from the parking lot information database 9, and the additional information in the database 11. A congestion prediction calculation device 22 is provided.
[0023]
Since the second embodiment is configured as described above, the frequency of collecting the data can be determined in consideration of past parking lot information, additional information such as event information and road information on the day. So, 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 time zone when it gets crowded can be shifted later, so consider this information By determining the frequency of data collection during the busy period and the low season, wasteful data collection can be suppressed during the low season and the increase in communication costs can be suppressed.
[0024]
FIG. 3 is a block configuration diagram showing a method for setting the frequency of data collection in each parking lot according to the 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 this embodiment, the frequency of data collection can be set in each parking lot. The point which was comprised is different.
[0025]
In FIG. 3, each parking lot 10 includes a parking number counter 13, a notification change number setting device 14, and the number of the parking number counter 13 based on the number set by the notification change number setting device 14. According to the output signal of the parking number change monitoring device 15 that generates an output when the set number of vehicles is exceeded, the fixed time interval timer 19 that outputs the output every predetermined time, and the parking number change monitoring device 15 or the fixed time interval timer 19 A notification activation device 16 for obtaining the number of parking number counters 13 is arranged.
[0026]
When the notification activation device 16 obtains the parking number from the parking number counter 13, the notification activation device 16 outputs the parking number together with the activation signal, and the activation signal is sent to the parking number change monitoring device 15 and the regular interval timer 19. It is given as a reset signal, and the parking number change value is set to zero, and the fixed interval timer value is set to zero.
[0027]
In each parking lot, a data notification device 17 and a communication device 18 for transmitting the parking lot data to the central monitoring centers 1A and 1B are arranged. When the parking number is received together with the activation signal from the notification activation device 16, the data notification device 17 sends the data to the communication device 18, and the communication device 18 sends the parking lot data to the central monitoring centers 1A and 1B.
[0028]
In the third embodiment, when the set number of vehicles is set to n by the notification change number setting device 14, the parking number change monitoring device 15 notifies the output signal when the value of the parking number counter 13 exceeds n. 16, the notification activation device 16 receives the numerical value of the parking number counter 13, transmits the value to the central monitoring center 1 </ b> A, 1 </ b> B via the data notification device 17 and the communication device 18, and starts from the notification activation device 16. The signal is sent to the parking number change monitoring device 15, and the count number of the parking number counter 13 is reset to zero.
[0029]
In addition, the activation signal from the notification activation device 16 resets the count number of the parking number counter 13 and also resets the regular interval timer 19. When this timer counts for a predetermined time, an output signal is sent to the notification activation device 16. 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 parked vehicle number change monitoring device 15 to reset the count number of the parked vehicle number counter 13 to zero and reset the fixed interval timer 19.
[0030]
As described above, the notification activation device 16 is driven by the signal of either the number-of-parking-change device 15 or the time interval timer 19 that is satisfied first in time, either for every predetermined number or for every fixed time interval.
[0031]
Therefore, even if the number of parking lots does not change at regular intervals because of the quietness of the parking lot, by adding the conditions for each prescribed number of vehicles, it is possible to Since data is collected in the direction that comes first in time, it can cope with the congestion period.
[0032]
Further, in the third embodiment, the notification change number can be arbitrarily set by the notification change number setting device 14 or the predetermined time interval by the fixed time interval timer 19, but the congestion shown in FIG. The prediction calculation device 22 may be accessed to determine the set number of the notification change number setting device 14 or the predetermined time interval of the regular interval timer 19 using the data of the congestion prediction calculation device 22.
[0033]
【The invention's effect】
As described in detail above, the present invention makes the frequency of data collection in the quiet period of the parking lot lower than the frequency of data collection in the busy period. Costs can be reduced.
[0034]
In addition, by setting the parking data collection time to either the predetermined number of parked vehicles or the time that was achieved first in time, even if the congestion period suddenly appears, Since data collection is performed, the frequency of data collection can be automatically increased.
