Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a parking lot vehicle management system that manages entry and exit of a parking lot of a vehicle, and a parking lot area control server and a parking lot management server used in the system, and is particularly applied to a large-scale parking lot. And a parking lot vehicle management system, a parking lot area control server, and a parking lot management server.
[0002]
[Prior art]
In recent years, large-scale parking lots have appeared. Among them, there is a parking lot in which a contract for monthly contract and a rental for time are mixed. Regardless of the increase in the size of the parking lot, there are not many systems for managing the entirety of the parking lot, and therefore, they often rely on guidance displays or manuals.
[0003]
Some parking management systems provide separate gates for monthly and hourly rentals on the premise that gates are provided at entrances and exits. In a parking lot, there is also a system for providing an in-vehicle detector in a parking section and managing the availability of parking.
[0004]
[Problems to be solved by the invention]
In the current parking lot, the following situations exist. For example, in a large-scale parking lot, there are cases where the inside of the parking lot is divided into several areas and classified according to symbols, colors, or the like, so as to be convenient when a user returns. However, in this case, it is necessary to memorize the symbols and colors, and if the user forgets them, the user takes time to find the vehicle.
[0005]
In addition, when monthly rentals and hourly rentals are mixed, if only the guidance display is displayed, the user may mistakenly recognize that the rentals are hourly and park in a monthly monthly space, which may cause a trouble. This cannot be prevented by the in-vehicle detector. To prevent this, for example, separate gates and parking sections may be provided for monthly use and time rental use. However, by allocating extra land to the installation of the gate, effective use of land cannot be achieved. Alternatively, it is conceivable to prevent a parking section from being mistaken by monitoring by a manager or a camera, but in this case, labor saving is hindered.
[0006]
In a parking lot, there are generally good and bad conditions, such as the presence or absence of a roof. However, it is actually difficult to set a fare based on good or bad conditions because vehicle control is required. At a flat rate, parking is concentrated in a space with good conditions, and effective use is not achieved.
[0007]
The present invention has been made in consideration of the above-described circumstances, and has a parking lot vehicle management system that manages the entrance and exit of a parking lot of a vehicle, and a parking lot area control server and a parking lot used in the system.

[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
In the parking lot vehicle management system as an embodiment, the management server holds information on the on-vehicle device mounted on the contract vehicle as a contractor table, and the area control server specifies a specific one of the plurality of bases. The information about the on-vehicle device mounted on the vehicle located in the parking lot is acquired by the communication from the vehicle, and the acquired information is passed to the management server. The management server further includes the contractor table. And the passed information are collated, and if the collation does not match, mismatch information is generated. This is a configuration for alerting a non-contracted vehicle entering a parking lot area corresponding to a specific one (a base corresponding to a monthly parking lot) among a plurality of bases.
[0016]
Further, the vehicle management system of the parking lot as an embodiment is connected to the area control server, and a vehicle detector that can be provided on a lane in the parking lot, and connected to the area control server, from the area control server A display for displaying information toward the lane in the parking lot according to the instruction of the area control server, wherein the area control server does not perform the communication from the specific one of the plurality of bases and When vehicle detection is performed by the vehicle detector, the display device is instructed to display alert information. When a vehicle that is not an ETC-compatible vehicle enters a monthly parking area, the vehicle is alerted.
[0017]
Further, the parking lot vehicle management system as an embodiment further includes a display connected to the area control server and displaying information toward the lane in the parking lot according to an instruction from the area control server. The management server instructs the area control server to display the alert information on the display based on the generated mismatch information. The warning for the non-contracted vehicle is performed using the display.
[0018]
Also. The parking lot vehicle management system as an embodiment further includes a user terminal connected to the management server and including an ETC card reader and a display unit, and the entrance server is mounted on a vehicle entering the parking lot. The on-board unit ID and the ETC card ID are obtained from the on-board unit and passed to the management server, and the area control server is obtained by the communication with the on-board unit mounted on a vehicle located in the parking lot. Each time the communication is performed, the OBE ID and the ETC card ID passed by the entrance server are transferred to the management server in association with the base where the communication was performed. Are recorded in association with each other, and time information is added to the vehicle-mounted device ID associated with the base passed by the area control server, When the in-vehicle device ID is not newly passed from the area control server within a predetermined time from the time of the time information to which the information is added, the associated base is associated with the in-vehicle device ID as parking area management information. Recording, the user terminal obtains an ETC card ID by the ETC card reader and passes the acquired ETC card ID to the management server, and the management server further obtains the recorded ETC card ID from the ETC card ID passed by the user terminal. The on-board unit ID is called, the associated base is called from the parking area management information using the called on-board unit ID, and the called base is transmitted to the user terminal. Further, the transmitted base is displayed on the display unit. The ETC card is read by the user terminal, and the area of the parked vehicle in the parking lot is shown on the display unit.
[0019]
In the parking lot vehicle management system according to the embodiment, the area control server communicates the vehicle-mounted device ID obtained by the communication with the vehicle-mounted device mounted on a vehicle located in the parking lot. Every time the communication is performed in association with the base, the communication is passed to the management server, and the management server adds time information to the vehicle-mounted device ID associated with the base passed by the area control server. The specific area parking information is recorded as the specific area parking information, and the recorded specific area parking information is passed to the exit server in response to a request from the exit server. The exit server uses the management server to generate the usage request data. The specific area parking information passed from is also used. The time information is associated with the area where the captured vehicle is located in the parking lot, and corresponds to the calculation of the breakdown of the parking time when the fee differs depending on the parking section.
[0020]
Based on the above, embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an example of a state where a vehicle management system for a parking lot is installed in an actual parking lot according to an embodiment of the present invention.
[0021]
As shown in FIG. 1, in this parking lot, parking sections 1 are arranged in a row, and a lane 2 is provided so that vehicles can enter and leave each parking section 1. Further, the lane 2 communicates with an entrance where the entrance antenna 3 is provided in the sky and a exit where the exit antenna 4 is provided in the sky. The entrance and exit are provided with hardware for managing entry and exit of the vehicle into and out of the parking lot. The configuration of this hardware will be described later.
[0022]
The entrance antenna 3 is connected to an entrance server (not shown), and the exit antenna 4 is connected to an exit server (not shown). The entrance antenna 3 and the exit antenna 4 wirelessly communicate with an on-vehicle device mounted on a vehicle.
[0023]
Area antennas 11 to 22 are provided at a plurality of positions above the lane 2 in the parking lot. These area antennas 11 to 22 serve as bases for communication with the vehicle-mounted device. Each of the area antennas 11 to 22 has a communicable range 11a to 22a, and these communicable ranges 11a to 22a do not overlap each other (if they do not overlap each other, they are shown in FIG. 1). Thus, there may be an area that does not belong to any of the communicable areas 11a to 22a of the area antennas.) The area antennas 11 to 22 are connected to an area control server (not shown).
[0024]
Furthermore, the entrance server, exit server, and area control server described above are connected to a management server (not shown). The management server obtains information from each of these servers as necessary, and performs processing to fulfill the function of newly providing the information. The information held or processed by the management server can be output to each server as needed.
[0025]
FIG. 2 is a diagram showing the entrance antenna 3 shown in FIG. 1 and the configuration of hardware connected thereto. FIG. 3 is a flowchart showing one typical operation flow performed using these configurations. Hereinafter, the operation using the entrance antenna 3 and the hardware connected thereto will be described with reference to FIGS.
[0026]
First, the first vehicle detection device 31 and the second vehicle detection device 32 detect the vehicle 30 that is going to enter the parking lot (step 41). This vehicle detection can be done, for example, by detecting a beam cut-off across the lane, as is commonly done in ETC systems. The two vehicle detection devices 31 and 32 are provided to confirm the flow direction of the vehicle based on the detection time difference.
[0027]
When the vehicle 30 to be entered is detected, a radio wave is emitted from the entrance antenna 3 toward the lane (step 42). Accordingly, when the vehicle-mounted device is mounted on the vehicle 30, the response is transmitted and can be received (step 43). The vehicle-mounted device is used in an ETC system, and is used by inserting an ETC card (credit card corresponding to the ETC), and can perform wireless communication with the outside.
[0028]
If there is a response from the vehicle-mounted device, subsequently, vehicle information is received from the vehicle-mounted device via the entrance antenna 3 (step 44). The vehicle information includes, for example, on-vehicle device ID, ETC card ID, information on the vehicle itself, and the like. The entrance server 36 transmits entrance information to the vehicle-mounted device via the entrance antenna 3 in response thereto (step 45). Here, the entrance information is, for example, entrance time information, parking lot identification information, and the like. These transmitted entrance information are held on the vehicle-mounted device side. In the vehicle-mounted device, a response indicating that the reception of the entrance information has been normally performed is transmitted to the entrance server 36 via the entrance antenna 3, and the entrance server 36 receives the response (step 46).
[0029]
If there is no response from the vehicle-mounted device in step 43 (if the vehicle is not ETC-compliant), and if the series of operations in steps 44 to 46 is not completed normally (in the case of the N side in step 47), parking is performed. A ticket is issued by the ticket issuing machine 33 (step 51). In these cases, it is intended to perform the settlement process using the parking ticket without using the ETC system.
[0030]
If the parking ticket has been removed (in the case of the Y side in step 52) and if the series of operations in steps 44 to 46 has been completed normally (in the case of the Y side in step 47), then the start controller The bar 34 is opened to urge the vehicle 30 to pass (step 48). When the vehicle 30 exits from the entrance into the parking lot (step 49), the bar of the start controller 34 is closed (step 50).
[0031]
The exit of the vehicle 30 can be detected by a third vehicle detection device 35 provided at the back of the start controller 34. The third vehicle detection device 35 also has the same vehicle detection principle as the first and second vehicle detection devices 31 and 32. Thus, the process of entering the parking lot of the vehicle 30 ends. A management server 37 is connected to the entrance server 36. An operation example including the management server 37 will be described later.
[0032]
FIG. 4 is a diagram showing the area antennas 11 to 22 shown in FIG. 1 and a configuration connected thereto. FIG. 5 is a flowchart showing one typical operation flow performed using these configurations. Hereinafter, the operation using the area antennas 11 to 22 and the configuration connected thereto will be described with reference to FIGS.
[0033]
When the vehicle 30 is located in the communicable range 11a to 22a of each of the area antennas 11 to 22 in the parking lot, communication between the vehicle-mounted device and the area control server 61 via each of the area antennas 11 to 22 can be performed. . The area control server 61 controls each of the area antennas 11 to 22 so that radio waves are sequentially emitted.
[0034]
That is, as shown in the flowchart of FIG. 5, a process 70a accompanying radio wave irradiation from the first area antenna 11, a process 70b accompanying radio wave irradiation from the second area antenna 12, ..., a twelfth area antenna The process 70c associated with the radio wave irradiation from 22 is performed, and the operation is repeated.
[0035]
The radio wave irradiation of each of the area antennas 11 to 22 and the associated processes 70a to 70c are specifically performed as follows. First, a radio wave is emitted from the area antenna 11 (..., 22) (step 71). When the vehicle 30 (vehicle compatible with ETC) is located in the communicable range 11a (..., 22a) of the area antenna 11 (..., 22), there is a response from the vehicle-mounted device of the vehicle 30 (Y side in step 72). Then, the vehicle information and the entrance information are continuously received from the vehicle-mounted device (step 73). The vehicle information and the entrance information do not necessarily have to be transmitted and received for all information. The specific information transmission request and reception are determined by the application.
[0036]
When the above information is received from the vehicle-mounted device, identification information unique to the area antenna is added (association is made), and the information is notified to the management server 37 (step 74). As a result, as long as the vehicle 30 located in the parking lot is present in the communicable range 11a (..., 22a) of the area antenna 11 (..., 22), the management server 37 captures its existence area. If the vehicle 30 (ETC-compatible vehicle) is not located in the communicable range 11a (..., 22a) of the area antennas 11 (..., 22), there is no response. Transition. Specific applications will be described later.
[0037]
FIG. 6 is a diagram showing the exit antenna 4 shown in FIG. 1 and the configuration of hardware connected thereto. FIG. 7 is a flowchart showing one typical operation flow performed using these configurations. Hereinafter, an operation using the exit antenna 4 and hardware connected thereto will be described with reference to FIGS.
[0038]
First, the first vehicle detection device 81 and the second vehicle detection device 82 detect the vehicle 30 that is about to leave the parking lot (step 91). This vehicle detection can also be done by detecting the interruption of the beam crossing the lane, as already described in FIG. The two vehicle detectors 81 and 82 are also provided to confirm the flow direction of the vehicle based on the detection time difference.
[0039]
When the exiting vehicle 30 is detected, the exit antenna 4 emits a radio wave toward the lane (step 92). As a result, when the vehicle-mounted device is mounted on the vehicle 30, the response is transmitted and can be received (step 93).
[0040]
If there is a response from the vehicle-mounted device, subsequently, vehicle information and entrance information are received from the vehicle-mounted device via the exit antenna 4 (step 94). As described above, the vehicle information includes, for example, the vehicle-mounted device ID, the ETC card ID, information on the vehicle itself, and the like. Similarly, the entrance information includes, for example, entrance time information and parking lot identification information.
[0041]
The exit server 86 calculates the parking fee from the entry time information and the exit time, generates usage statement information, and transmits this and exit information (hereinafter referred to as exit information) to the vehicle-mounted device via the exit antenna 4. Transmit (step 95). Here, the exit information is, for example, exit time information, parking lot identification information, and the like. These transmitted exit information may be retained on the vehicle-mounted device thereafter. In the vehicle-mounted device, a response indicating that the exit information has been normally received is sent to the exit server 86 via the exit antenna 4, and the exit server 86 receives the response (step 96).
[0042]
The exit server 86 generates billing information from the ETC card ID and the usage statement information, and separately performs settlement with the credit company. (Even if the exit server 86 is used, the information generated by the exit server 86 may be used. May be passed to the management server 37 and the management server 37 may be used, or a payment server may be separately prepared and used.)
[0043]
If there is no response from the vehicle-mounted device in step 93 (if the vehicle is not an ETC-compatible vehicle), it is considered that the user has a parking ticket issued in advance, so that the parking ticket is not inserted into the exit payment device 83. Wait (step 101). As long as the parking ticket is not inserted, the transmission of the radio wave from the exit antenna 4 is tried again. When the parking ticket is inserted into the exit adjuster 83, the exit adjuster 83 performs a settlement process (step 102). The result of the settlement process is displayed on the display 87. As a result, the driver can make a payment using the exit payment device 83 (step 103). If the settlement is not completed normally, a staff member responds (step 104). Since the above-mentioned settlement by the parking ticket is a well-known matter, further detailed description is omitted.
[0044]
When the payment processing by the parking ticket is completed (Y side of step 103) and when a series of operations of steps 94 to 96 are normally completed (Y side of step 97), the vehicle is started. The bar of the controller 84 is opened to prompt the vehicle 30 to pass (step 98). When the vehicle 30 exits the parking lot from this exit (step 99), the bar of the start controller 84 is closed (step 100). The exit of the vehicle 30 can be detected by the third vehicle detection device 85 provided at the back of the start controller 84. The third vehicle detection device 85 also has the same vehicle detection principle as the first and second vehicle detection devices 81 and 82.
[0045]
If the series of operations in steps 94 to 96 is not completed normally (N side in step 97), neither the above-mentioned automatic payment nor the payment using a parking ticket can be performed. (Step 104). Thus, the exit processing of the vehicle 30 from the parking lot is completed. The management server 37 is connected to the exit server 86. An operation example including the management server 37 will be described later.
[0046]
FIG. 8 is a configuration diagram illustrating a first application example (application) in the embodiment described above. In FIG. 8, the components already described are given the same numbers. This application example is suitable, for example, when the inside of a parking lot is divided into a monthly service and a time rental service.
[0047]
When there is such a mixture of monthly rentals and hourly rentals, it is necessary to effectively prevent a non-contracted vehicle from being accidentally parked in the monthly parking lot. Here, in the parking lot shown in FIG. 1, each parking section 1 included in the area substantially defined by the communicable range 13a, 14a, 17a, 18a of the area antennas 13, 14, 17, 18 is for monthly use. This will be described below. This area is hereinafter referred to as a monthly usage area.
[0048]
The area control server 61 is provided in the communicable range 13a, 14a, 17a, 18a of the area antennas 13, 14, 17, 18 on the side facing the roadway 2 in association with the area antennas 13, 14, 17, 18. The vehicle detectors 13b, 14b, 17b, 18b are connected to the indicators 13c, 14c, 17c, 18c, respectively. In the management server 37, the above-mentioned monthly usage area is set, and information (for example, on-vehicle device ID) on the vehicle-mounted device mounted on the vehicle of the monthly contract is registered in advance, and this information is registered by the contractor. It is held and managed as a table 37a. The vehicle detectors 13b, 14b, 17b, and 18b detect entry of a vehicle by detecting, for example, interruption of a beam emitted in a direction crossing the lane 2.
[0049]
In the above configuration, when the vehicle 30 equipped with the vehicle-mounted device enters the monthly usage area, information about the vehicle-mounted device is managed via the area control server 61 from the area antenna 13, 14, 17, or 18 existing in the monthly usage area. It is transmitted to the server 37. The management server 37 collates the sent information on the vehicle-mounted device with the contractor table 37a. If the information matches, the management server 37 determines that it is a monthly contractor use, and does not perform any processing.
[0050]
If the collation results are inconsistent, it is determined that there is an erroneous approach other than the contracted vehicle, and the management server 37 notifies the area control server 61 of the alert information. Upon receiving this notification, the area control server 61 instructs the displays 13c, 14c, 17c, and 18c to display the alert information. As a result, it is possible to alert the driver of the vehicle 30 of the monthly usage area.
[0051]
On the other hand, when a vehicle not equipped with an on-vehicle device enters, it is not possible to obtain information by wireless communication via the area antennas 13, 14, 17, and 18, but from the vehicle detectors 13b, 14b, 17b, and 18b. It is possible to obtain entry information of the vehicle. When only the vehicle detectors 13b, 14b, 17b, and 18b react, it is determined that the non-ETC-compliant vehicle has erroneously entered the monthly use area, and the area control server 61 displays the display 13c, 14c, 17c, 18c. The user is instructed to display alert information.
[0052]
As described above, it is possible to easily realize a system that issues a warning (alert) when a vehicle enters a specific area such as a monthly usage area. This makes it possible to effectively prevent a non-contracted vehicle from being erroneously parked in a monthly parking lot, for example, in a parking lot where both monthly and hourly rentals are mixed.
[0053]
FIG. 9 is a configuration diagram illustrating a second application example in the embodiment described above. In FIG. 9, the components already described are given the same numbers. This application example is suitable as a system for instructing a user on an area where a vehicle is parked when the user returns to a parking lot.
[0054]
In a large-scale parking lot, it is assumed that the user forgets where he or she parked, or loses direction at night or the like. Therefore, in addition to the basic system configuration, a user terminal 111 is provided by connecting to the management server, and guidance display is performed.
[0055]
The user terminal 111 includes an ETC card reader 111a, a display unit 111b for performing guidance display, an operation unit 111c capable of inputting buttons, and a control unit 111d for controlling these units.
[0056]
The operation of this application example will be described. When the vehicle 30 equipped with the vehicle-mounted device enters from the entrance, the entrance server 36 acquires the vehicle-mounted device ID and the ETC card ID from the vehicle-mounted device via the entrance antenna 3. The acquired in-vehicle device ID and ETC card ID are transmitted from the entrance server 36 to the management server 37. The management server 37 holds this information.
[0057]
Next, the vehicle-mounted device of the vehicle 30 that has entered the parking lot communicates with the area control server 61 via the area antennas 11 to 22 as the vehicle 30 moves. The vehicle-mounted device ID and the identification information unique to the area antennas 11 to 22 obtained by this communication are transmitted from the area control server 61 to the management server 37. The management server 37 estimates the parking area of the vehicle 30 as follows based on the temporal change of the information transmitted in this manner. Here, it is assumed that the “parking area” is set corresponding to the communicable range 11 a to 22 a of each of the area antennas 11 to 22.
[0058]
If the vehicle 30 is parked in the parking area corresponding to the communicable range 19a, the information is stored in the area via the area antennas 11 to 18 and 20 to 22 corresponding to other parking areas after a certain period of time. The control server 61 does not notify the management server 37. Thus, the management server 37 can estimate that the vehicle 30 has parked in the parking area corresponding to the communicable range 19a.
[0059]
If the parking area corresponding to the communicable range 19a is full, the vehicle moves to the parking areas 15 and 20 corresponding to the communicable range 19a. The control server 61 notifies the management server 37. Similarly, while the vehicle 30 moves, the management server 37 captures the vehicle-mounted device ID and the identification information unique to the area antennas 11 to 22.
[0060]
Therefore, when the vehicle-mounted device ID obtained from a certain area antenna is not notified to the management server 37 by communication via the next assumed area antenna after a certain period of time elapses (in this case, the power supply of the vehicle-mounted device is turned off in the vehicle 30). In this case, the parking area corresponding to the communicable range of the area antenna with which communication was performed last can be estimated as the parking area of the vehicle 30.
[0061]
Here, in order to determine the elapse of the “certain time”, when the vehicle-mounted device ID and the identification information unique to the area antennas 11 to 22 are notified to the management server 37, the time information is added thereto. You should leave it. Then, by measuring the progress from this time, the management server 37 can determine the progress of the “certain fixed time”. Note that a specific numerical value of the “certain time” can be set to, for example, about 1 minute to 5 minutes depending on the actual situation.
[0062]
The parking area estimated as described above is held and managed as parking area management information 37b in the management server 37 in association with the vehicle-mounted device ID. The parking area management information 37b is a set of unique information indicating one of the area antennas 11 to 22 for one vehicle-mounted device ID, and is not stored in the time direction, so that the storage area information is very small. All you need is enough memory. The exit area 86 may notify the management server 37 of the exit when the exit server 86 performs exit processing, and the parking area management information 37b may be deleted from the parking area management information 37b. This saves memory capacity since no data is stored.
[0063]
When the user parks the vehicle 30 in any one of the parking sections 1, the user removes the ETC card from the vehicle-mounted device and leaves the vehicle 30. However, when the user tries to return to the vehicle 30 after completing the business, the user Can use the user terminal 111 with an ETC card. That is, an inquiry is sent from the user terminal 111 to the management server 37 by inserting the ETC card into the card reader 111a of the user terminal 111 and reading the ETC card and performing necessary button operations on the operation unit 11c. This inquiry is accompanied by the ETC card ID.
[0064]
The management server 37 searches the held information for the vehicle-mounted device ID corresponding to the ETC card ID. Furthermore, the vehicle-mounted device ID obtained by the search is collated with the parking area management information 37b, whereby the parking area can be determined. The determined parking area is transmitted to the user terminal 111, and the guidance of the parking area can be displayed on the display unit 111b.
[0065]
As described above, in this application example, it is possible to easily realize a system for guiding the parking lot area where the vehicle 30 is parked. This makes it easy for the user to return home, for example, when the user is very large and it is difficult for the user to memorize the parking position, or when the direction is complicated.
[0066]
FIG. 10 is a configuration diagram illustrating a third application example in the above-described embodiment. In FIG. 10, the components already described are denoted by the same reference numerals. This application example is a system suitable for setting different fees for each parking area.
[0067]
In such a system, since the parking area can be specified by using the “parking area management information 37b” similar to the second application example, by transmitting the parking area information from the management server 37 to the exit server 86, Can be realized for the time being.
[0068]
However, since the second application example is intended for guidance, the processing is simplified, and it is not practical to apply the second application example as it is when setting different rates for each parking area. For example, in the simplest case, even when the user finishes his business and returns to the vehicle 30, the vehicle-mounted device is turned on and wireless communication is resumed, the area antennas 11 to 22 and the area control server corresponding to the parking area are also provided. If information such as the vehicle-mounted device ID is notified to the management server 37 via 61, it is possible to temporarily confirm that the vehicle is parked in the parking area continuously.
[0069]
However, when the content of the parking area management information 37b is different from the information obtained after the resumption, there is a problem of how to determine. For example, if the user intentionally enters an area (specific area) where the set fee is low, determines the contents of the parking area management information 37b, and immediately re-parks in an area where the set fee is high immediately after this, such a case is obtained. Mismatch occurs.
[0070]
Therefore, in the third application example, when communication with the vehicle-mounted device via the area antennas 11 to 22 is notified from the area control server 61 to the management server 37, the management server 37 adds time information to them. Record it as a communication log. This communication log is information for specifying the time and confirming that the vehicle has been parked in the specific area (area where the set fee is low), and is hereinafter referred to as “specific area parking information 37c”. The communication log is, for example, information according to a time series as shown in FIG. 11 for each vehicle-mounted device ID. In FIG. 11, “area number” is identification information unique to the area antennas 11 to 22.
[0071]
According to the specific area parking information 37c, when the exit server 86 determines the actual parking fee, the time at which the communication in the specific area is interrupted recorded in the management server 37 and the re-communication in the specific area are performed. The difference is calculated from the start time, and this difference can be used as the specific area parking time. Further, even when the vehicle is parked without stopping the engine and its position is within any of the communicable ranges 11a to 22a of the area antennas 11 to 22, the communication with the vehicle-mounted device is continued and managed. The server 37 records a communication log, whereby it is possible to calculate the parking time of a specific area.
[0072]
Furthermore, if the area antenna is arranged so as to cover the parking space without omission, for example, when the specific area is set as the communicable range 14a, the communicable range 13a adjacent to the communication time in the communicable range 14a , 17a, and 18a may be calculated as the specific area parking time. In this case, the vehicle is always located in any communicable range while the vehicle-mounted device is on (that is, while the vehicle 30 is movable).
[0073]
The specific area parking information 37c created and managed by the management server 37 is output to the exit server 86 based on the vehicle-mounted device ID in response to a request from the exit server 86. As a result, the exit server 86 can perform exit processing such as transmission of usage statement information to the vehicle 30 to be exited.
[0074]
Although the embodiment has been described above, various arrangements of the area antenna other than the example shown in FIG. 1 are conceivable. For example, the inside of a parking lot may be divided into a plurality of areas, and an area antenna that emits radio waves only to the lane 2 corresponding to the entrance to those areas may be provided.
[0075]
【The invention's effect】
As described above in detail, according to the present invention, in addition to the entrance server performing the entrance processing to the parking lot and the exit server performing the exit processing from the parking lot, the vehicle-mounted device mounted on the vehicle located in the parking lot An area control server is provided which attempts communication with the server from a plurality of bases provided in the parking lot. Thereby, the area where the vehicle exists in the parking lot can be captured, and the area information where the vehicle exists in the parking lot obtained by the area control server can be sent to the management server and managed. Therefore, it is possible to manage the position of the vehicle in the parking lot.
