Abstract

PROBLEM TO BE SOLVED: To search an absent transmitter which does not exist in its own regular position by using a mobile terminal of a user.SOLUTION: A mobile terminal of a user B successively acquires its own current position. When there is a regular position of any one of transmitters 30 in the vicinity thereof, regardless of whether the transmitter 30 exists in the regular position or not, the transmitter 30 is set as the current target transmitter, and an identification code of the target transmitter is acquired as the target identification code in accordance with a predetermined relationship between the regular position and the identification code. When the mobile terminal does not receive an identification signal from any transmitter at substantially the same position as the current position or when the mobile terminal receives an identification signal from any transmitter but the identification code represented by the identification signal does not coincide with the target identification code, it is determined that the target transmitter does not exist in its own regular position.SELECTED DRAWING: Figure 5

  Referring to FIG. 1, a parking lot management system (hereinafter simply referred to as “system”) 10 according to an exemplary embodiment of the present invention includes a plurality of parking lots 20 (in FIG. Only representative parking lots A, B and C are shown). Although not shown, each parking lot 20 has a plurality of vehicle compartments (that is, a space allocated to one vehicle to be parked), and a plurality of vehicles can be parked in the vehicle compartments.

  The parking lot management system according to the present embodiment is configured to execute the parking lot management method according to the present embodiment.

  Each parking lot 20 is unmanned. Furthermore, in order to reduce and simplify the facilities, each parking lot 20 also includes a gate device that opens and closes appropriately to prevent the unauthorized vehicle from coming out from the entrance / exit of the parking lot 20. The car stop device that protrudes from the ground and is buried in the ground as needed to prevent the car from being issued is also a ticket issuing machine that issues a parking ticket to the user who is a driver on the condition of paying the parking fee and a checkout There is no machine installed.

  Note that the term “vehicle” should be construed throughout the specification as a term encompassing not only automobiles but also all kinds of moving objects such as bicycles and motorcycles.

  In addition, the term “parking space” refers to a single parking lot 20 throughout the specification, or each of a plurality of compartments in the single parking lot 20 or a collection of a plurality of compartments (for example, , A plurality of vehicle compartments adjacent to each other). In the present embodiment, one parking lot 20 constitutes an example of “one parking space”.

  In addition, the term “code” means “a string of numbers and / or symbols” throughout the specification, specifically, a numerical notation that digitizes and expresses the state of an analog signal, A numerical notation specific to each analog signal. The term “code” is referred to as an ID or identifier, for example, depending on the application.

  By the way, as a management method of the parking lot 20, a self-supporting management method in which each parking lot 20 is managed independently (individually or self-contained) using only the facilities installed in the parking lot 20. There is a centralized management method for centrally managing the parking lots 20 by communicating with a management server 50 (see FIG. 1) in which a plurality of parking lots 20 are remote. The system 10 according to the present embodiment employs the above-described centralized management method as the parking lot management method.

  Specifically, as shown in FIG. 1, this system 10 is installed in a transmitter 30 installed in each parking lot 20 and a management center 40 that centrally manages a plurality of parking lots 20. The management server 50 is provided.

  In the present embodiment, a plurality of vehicle compartments are installed in the same parking lot 20, and one transmitter 30 is used in common in the vehicle compartments. However, the present invention may be implemented in a mode in which one transmitter 30 is used for each vehicle compartment. In this aspect, one vehicle compartment constitutes an example of “one parking space”.

  Each transmitter 30 is configured to transmit an identification signal representing a transmitter ID unique to the transmitter 30 (an example of the aforementioned “transmitter code”). Since one transmitter ID is also unique to one parking lot 20, as will be described later, one transmitter ID is associated one-to-one with one parking lot ID (an example of the aforementioned “parking lot code”).

  As shown in FIG. 2, in this system 10, the user uses the mobile terminal 90 of his / her own mobile terminal 90 to receive the identification signal described above from the transmitter 30 installed in the parking lot 20 where the user is currently staying. In a contact state or a non-contact state with the transmitter 30, the short-distance one-way wireless communication method is used, and long-distance two-way wireless communication is performed with the management server 50 of the management center 40.

  The user's portable terminal 90 is a device that is carried by the user and has a wireless communication function, such as a mobile phone, a smartphone, a laptop computer, a tablet computer, and a PDA.

<Outline of system configuration>
In this system 10, the mobile terminal 90 and the management server 50 are both a parking mode for the user to park in any parking lot 20 selected by the user, and a plurality of transmitters 30. And a search mode for searching for a non-existing transmitter that does not exist at the normal position of the first.

<Transmitter>

  Here, a hardware configuration (see FIG. 3) and a software configuration (see FIG. 4) will be described with respect to one transmitter 30 representing the plurality of transmitters 30 in FIG.

  First, to explain conceptually, at least one transmitter 30 is installed in the corresponding parking lot 20 and transmits an identification signal that can identify a unique parking lot ID in the corresponding parking lot 20. Or it is a contact-type communication device. The transmitter 30 only needs to have at least a transmission function, but may be configured to have a reception function as necessary.

  Next, in order to explain the operation method, the transmitter 30 actively transmits a unique identification signal without requiring a trigger signal from the outside, and permanently unless supply power is insufficient.

  The transmitter 30 is a device that is generally known by a name such as a beacon device that transmits a beacon signal as an identification signal or a radio beacon. In one example, the transmitter 30 generates an identification signal representing a corresponding parking lot ID by modulating an original signal, and the generated identification signal is converted into an IR signal, a Bluetooth (registered trademark) signal, an NFC, and the like. (Short-range wireless communication) Signals are transmitted.

  Next, the hardware configuration will be described with reference to FIG. 3 which is a functional block diagram. The transmitter 30 includes a computer 104 having a processor 100 and a memory 102 for storing a plurality of applications executed by the processor 100. It is configured as a subject.

  The transmitter 30 further includes a replaceable disposable battery 106 as a power source. Instead of the battery 106, a rechargeable battery, a commercial power supply as an external power supply, or a generator (for example, a transponder) that generates power using an external magnetic field can be used. .

  The transmitter 30 further includes a transmitter 108 that generates and transmits an identification signal. The transmitter 108 is operated by the battery 106 and is controlled by the controller 110. The controller 110 is controlled by the computer 100.

  The transmitter 30 may be installed on the ground so as not to be mechanically fixed to the ground of the parking lot 20, that is, to be easily removable from the ground, for example. In other words, each transmitter 30 is not physically fixed at a corresponding position (corresponding parking lot 20) in space. This is because the owner of the land operated as the parking lot 20 requested the management company to operate as the parking lot 20 for a certain period, but the request may be canceled suddenly.

  In such a case, the management company promptly removes all facilities for the parking service from the parking lot 20, and at that time, in order to minimize the effort for restoring the current situation, the transmitter 30 is simply It can be placed on the ground of the land. Therefore, the transmitter 30 is different from the parking lot 20 where the transmitter 30 is normally installed due to an illegal act by someone, contrary to the intention of the parking lot management company (for example, a parking lot that is normally installed). There is a possibility that it will be installed in another parking lot away from 20 or another place that does not correspond to the parking lot 20 that is normally installed.

  Next, the software configuration of the transmitter 30 will be described with reference to FIG. 4. The processor 100 of the transmitter 30 repeatedly executes the program conceptually represented in the flowchart of FIG.

  When each program is executed, first, the transmitter ID is read from the memory 102 in step S1. The transmitter ID corresponds one-to-one with the parking lot ID assigned to one parking lot 20 where the transmitter 30 is installed.

  Subsequently, in step S2, a signal for modulating an original signal (for example, a carrier signal) is output to the controller 110 so that the read transmitter ID is reflected. The controller 110 controls the transmitting unit 108, and as a result, the transmitting unit 108 generates an identification signal to be transmitted this time. Thereafter, in step S3, the generated identification signal is transmitted from the transmitter 108. Then, it returns to step S1.

  Here, in order to explain one function of the user's portable terminal 90 in association with the transmitter 30, the portable terminal 90 receives the identification signal from the transmitter 30 and the computer 134 of the portable terminal 90. When a certain program installed in advance (see FIG. 6) is activated, the received identification signal is demodulated in real time, thereby decoding the transmitter ID in real time.

  Furthermore, the portable terminal 90 received the identification signal and the position of the transmitter 30 when the identification signal was transmitted based on the received identification signal while receiving the identification signal from the transmitter 30. The distance between the mobile terminal 90 and the position of the mobile terminal 90 is also measured.

  That is, the portable terminal 90 acquires both the transmitter ID corresponding to the transmitter 30 and the distance to the transmitter 30 at that time based on the identification signal received from the transmitter 30. It is.

  When the user of the portable terminal 90 approaches the transmitter 30 while holding his / her own portable terminal 90 and makes the portable terminal 90 completely or substantially contact the transmitter 108 of the transmitter 30, the portable terminal 90 is The identification signal can be received from the transmitter 30 in a contact manner.

  On the other hand, when the user of the mobile terminal 90 enters the specific reception area while holding his / her mobile terminal 90, the mobile terminal 90 can receive the identification signal from the transmitter 30 in a non-contact manner.

  As conceptually shown in a plan view in FIG. 5, each transmitter 30 is assigned two types of reception areas. They are a receivable area and an effective receiving area. Each of these areas is generally defined by a circle originating from each transmitter 30, and the receivable area has the maximum reception radius, while the effective reception area is the effective reception radius (ie, the effective reception radius described below). Receiving distance R).

  However, specifically, when the power supply of each transmitter 30 is normal, the receivable area is an area where the identification signal from the transmitter 30 is reachable, that is, as long as it exists in the area. It means an area where the portable terminal 90 can receive the identification signal.

  On the other hand, the effective reception area has an effective reception radius smaller than the maximum reception radius of the receivable area. The maximum reception radius cannot be arbitrarily set, whereas the effective reception radius can be arbitrarily set.

  That is, the maximum reception radius may mean a reception limit determined by hardware, whereas the effective reception radius may mean a reception limit determined by software.

  As described above, the portable terminal 90 measures the distance from the transmitter 30 when the received identification signal is transmitted. The distance measurement may or may not exceed the effective reception radius. When the distance measurement value does not exceed the reception effective radius, the mobile terminal 90 exists in the effective reception area, whereas when the distance measurement value exceeds the reception effective radius, the mobile terminal 90 Is present in the receivable area but not in the effective reception area.

  After receiving the identification signal from the transmitter 30, the portable terminal 90 determines whether or not the distance measurement value is less than or equal to the set value of the effective reception radius. Is currently located within the effective reception area, the portable terminal 90 determines that “the identification signal from the transmitter 30 has been received effectively (hereinafter also simply referred to as“ the identification signal has been received ”)”.

  On the other hand, when the mobile terminal 90 determines that the distance measurement value is larger than the set value, the mobile terminal 90 is currently located outside the effective reception area. It is determined that the signal is not received effectively (hereinafter also simply referred to as “the identification signal is not received”).

  That is, in the present embodiment, when the mobile terminal 90 is located outside the effective reception area, the mobile terminal 90 actually appears even though the mobile terminal 90 receives the identification signal. It is handled on the software that the identification signal has not been received.

  In the present embodiment, each transmitter 30 is arranged such that at least the effective reception area of the receivable area and the effective reception area of each transmitter 30 does not overlap with at least the effective reception area of another transmitter 30. Individual performance and relative positional relationship, and set values of the effective reception radius are set.

  Furthermore, in the present embodiment, the effective reception distance R is a value R1 (for example, within a range of 0 cm to 50 cm or within a range of 30 cm to 50 cm) when the parking mode is executed by the mobile terminal 90, as will be described later. When the search mode is executed, the value R2 is changed to be longer than the value R1 (for example, within a range of 50 m to 70 m).

  Furthermore, in the present embodiment, the effective reception distance R is set to be shorter than a measurement error when the mobile terminal 90 measures its current position on a map. According to this setting, due to a positioning error of the mobile terminal 90, the presence / absence determination of the transmitter 30 may be erroneously performed for a normal position different from the normal position specified using the mobile terminal 90. To reduce.

  Furthermore, in the present embodiment, it is determined that no signal is received unless the strength at which the mobile terminal 90 receives any signal exceeds the reference value. In this case, of course, it is determined that a signal from any transmitter 30 is not received.

<Mobile device>

  Next, the hardware configuration of the user's mobile terminal 90 will be described with reference to FIG. 6 which is a functional block diagram. The mobile terminal 90 includes a processor 130 and a memory for storing a plurality of applications executed by the processor 130. A computer 134 having 132 is mainly configured.

  The portable terminal 90 further includes a display unit (for example, a liquid crystal display) 136 that displays information on a screen (having a window having a finite area that is variable or invariable), for example, shown in FIG. The receiving unit 138 receives signals from the transmitter 30 and the management server 50, and the transmission unit 140 generates a signal and transmits the signal to the management server 50.

  The portable terminal 90 further includes an input unit 150 for inputting data and commands from the user. The input unit 150 includes, for example, an operation unit that can be operated by the user to input desired information (for example, commands, data, and the like) to the mobile terminal 90. The operation unit includes a touch screen that displays icons (for example, virtual buttons) that can be operated by the user, a physical operation unit (for example, keyboard, keypad, and buttons) that can be operated by the user, and voice. There is a microphone to detect, but it is not limited to these.

  The portable terminal 90 further includes a GPS (satellite positioning system) receiver 152. As is well known, the GPS receiver 152 receives a plurality of GPS signals from a plurality of GPS satellites, and based on the GPS signals, determines the position (latitude, longitude, and altitude) of the GPS receiver 152 on the earth. Measure by triangulation.

  The portable terminal 90 further has a function of measuring its own moving speed on the ground (for example, the speed of translational movement of the mass point when the portable terminal 90 is regarded as the mass point). The moving speed is measured, for example, by differentiating a plurality of current positions that are sequentially measured.

<Management server>

  Next, the hardware configuration of the management server 50 will be described with reference to FIG. 7 which is a functional block diagram. The management server 50 includes a processor 160 and a memory 162 that stores a plurality of applications executed by the processor 160. The computer 164 is mainly configured.

  The management server 50 further generates a signal by displaying a display unit (for example, a liquid crystal display) 166 that displays information, a receiving unit 168 that receives a signal from the portable terminal 90, and transmits the signal to the portable terminal 90. And a clock 172 that measures the current time. This management server 50 does not directly receive from the transmitter 30, but in effect via the mobile terminal 90.

<Parking mode>

  In FIG. 8, in the parking mode, an example of communication performed between the transmitter 30 and the portable terminal 90 both located in the same parking lot 20 and the management server 50 located in a remote place is sequenced in time series. It is represented by a flow.

  The transmitter 30 spontaneously and continuously transmits an identification signal unique to itself.

  First, the mobile terminal 90 responds to the user's operation on the mobile terminal 90, shifts to the parking mode in step S <b> 101, and transmits parking mode shift data indicating that to the management server 50.

  On the other hand, the management server 50 receives the parking mode transition data in step S201, and shifts itself to the parking mode.

<Receiving mode>

  Next, the portable terminal 90 responds to the user's operation on the portable terminal 90, and sets the effective reception distance R to the value R1 in step S102. Subsequently, in step S103, the process shifts to the warehousing mode, and warehousing mode transition data indicating that is transmitted to the management server 50.

  On the other hand, the management server 50 receives the warehousing mode shift data in step S202, and shifts itself to the warehousing mode.

  Thereafter, the user brings the portable terminal 90 close to or in contact with the transmitter 30 existing in the parking lot 20 actually selected by the user. As a result, the mobile terminal 90 is ready to receive a signal from the current transmitter 30.

  Subsequently, in step S <b> 104, the mobile terminal 90 determines whether or not the mobile terminal 90 has effectively received the identification signal from the transmitter 30. When the reception intensity of the mobile terminal 90 is equal to or lower than the reference value, it is determined that no identification signal from any transmitter 30 has been received.

  Even if the transmitter 30 exists in the vicinity, if the portable terminal 90 is currently located outside the receivable area of the transmitter 30, the portable terminal 90 cannot receive the identification signal from the transmitter 30 at all.

  On the other hand, when the mobile terminal 90 is currently located within the receivable area, the mobile terminal 90 can receive the identification signal from the transmitter 30.

  In this case, in this step S104, the distance between the current transmitter 30 and the portable terminal 90 is further measured based on the received identification signal. In this step S104, whether or not the distance measurement value is smaller than the effective reception distance R (this time is equal to the value R1), that is, when the mobile terminal 90 currently has the effective reception distance R of the value R2. It is determined whether it is located in a narrower effective reception area. In short, in this step S110, it is determined whether or not the portable terminal 90 has identified any transmitter 30.

  In the example shown in FIG. 5, the mobile terminal 90 of the user A is present within the effective reception area defined by the short effective reception distance R <b> 1, so that the identification signal is effectively received from the transmitter 30.

  If the distance measurement value is smaller than the effective reception distance R, the mobile terminal 90 has identified one of the transmitters 30, and thus the process proceeds to step S <b> 105. Warehousing (start of parking service) is not permitted by the user, and the process returns to step S101, for example.

  If the distance measurement value is smaller than the effective reception distance R, then, in step S105, the received identification signal is demodulated, and the transmitter ID represented by the demodulated identification signal is decoded. That is, the current transmitter 30 is specified.

  When the demodulated identification signal is a code expressed in a binary number of multiple digits, for example, the code is a conversion table prepared in advance (for example, one downloaded in advance from the management server 50). Is converted into a transmitter ID. However, in terms of usage, the difference between “code” and “ID” is not important as long as its use is identification.

  Subsequently, in step S106, the acquired transmitter ID is converted into a parking lot ID by referring to a table (not shown) representing a one-to-one relationship between the transmitter ID and the parking lot ID. . The parking lot ID is stored in the memory 132 of the mobile terminal 90.

  Thereafter, in step S107, an entry button 200 (see FIG. 5 (virtual buttons displayed with characters, symbols, images, etc.)) as an operation unit selected for the user to request entry is displayed on the screen 135. Is displayed. Subsequently, in step S108, the user touches the warehousing button with a finger to select and activate the warehousing button 200.

  Thereafter, in step S109, the parking lot ID thus decoded is transmitted to the management server 50 together with the user ID assigned in advance to the current user.

  On the other hand, the management server 50 receives the transmitted parking lot ID together with the current user ID in step S203. Thereafter, in step S204, necessary authentication related to the parking lot and the user is performed based on the reception results. If the authentication is successful, the current user is permitted to park in the current parking lot 20 in step S205. .

  Subsequently, in step S206, using the clock 172, the current time is recognized as the warehousing time. The warehousing time is stored in the memory 162 in association with the current parking lot ID and the current user ID.

  With the above, one warehousing mode is completed.

<Shipping mode>

  In response to the user's operation on the portable terminal 90, the portable terminal 90 shifts to the shipping mode in step S <b> 110, and transmits shipping mode transition data indicating that to the management server 50.

  On the other hand, the management server 50 receives the delivery mode transition data in step S207, and shifts itself to the delivery mode.

  Subsequently, in step S111, the portable terminal 90 displays on the screen 135 a delivery button 202 (see FIG. 5 (characters, symbols, images, etc.) as an operation unit selected for the user to request delivery. Display a virtual button)). Subsequently, in step S112, the user selects the delivery button 202.

  Subsequently, similarly to step S <b> 104, in step S <b> 113, it is determined whether or not the mobile terminal 90 has effectively received the identification signal from the transmitter 30.

  Thereafter, similarly to step S105, in step S113, the received identification signal is demodulated, and the transmitter ID represented by the demodulated identification signal is decoded. Subsequently, in the same manner as in step S106, the decoded transmitter ID is converted into a parking lot ID in step S114.

  Thereafter, in step S116, the parking lot ID is checked against the parking lot ID stored in the memory 132 of the portable terminal 90.

  If the verification is successful, in step S117, a confirmation button 204 (see FIG. 5 (displayed with characters, symbols, images, etc.) as an operation unit selected for the user to request continuation of the exit procedure is displayed on the screen 135. Display virtual buttons)). Subsequently, in step S1182, the user selects the confirmation button 204.

  Thereafter, in step S119, the delivery confirmation data indicating that the confirmation button 204 has been selected by the user is transmitted to the management server 50 together with the current parking lot ID and the current user ID.

  On the other hand, in step S208, the management server 50 receives the delivery confirmation data together with the current parking lot ID and the current user ID. Subsequently, in the same manner as in step S204, in step S209, necessary authentication relating to the parking lot and the user is performed based on the reception results.

  If the authentication is successful, the current time is recognized as the delivery time by using the clock 172 in step S210. The delivery time is stored in the memory 162 in association with the current parking lot ID and the current user ID.

  Subsequently, in step S211, the parking time is calculated by subtracting the entry time stored in the memory 162 from the delivery time.

  With the above, one delivery mode ends.

<Search mode>

  FIG. 9 shows an example of communication performed between the transmitter 30 and the portable terminal 90 located in the same parking lot 20 and the management server 50 located in a remote place in time series in the search mode. It is represented by a flow.

  The transmitter 30 spontaneously and continuously transmits an identification signal unique to itself.

  First, the portable terminal 90 responds to a user operation on the portable terminal 90, shifts to the search mode in step S301, and transmits search mode shift data indicating that to the management server 50. The portable terminal 90 executes this search mode in the background. As a result, this search mode can be executed without the user of the mobile terminal 90 noticing.

  On the other hand, in step S401, the management server 50 receives the search mode shift data and shifts itself to the search mode.

  Next, in step S302, the portable terminal 90 sets the effective reception distance R to a value R2 (> R1). Thereby, the portable terminal 90 can search for the transmitter 30 in a wider range than when the parking mode is executed.

  Subsequently, in step S303, the current position (latitude and longitude) P of the user is measured based on the GPS signal received from the outside by the GPS receiver 152. Thereafter, in step S304, the moving speed V of the portable terminal 90 is measured as described above.

  Subsequently, in step S305, current position data representing the measured current position P (including the longitude and latitude of the current position) and movement speed data representing the measured movement speed V are transmitted to the management server 50.

  On the other hand, the management server 50 receives the current position data and the moving speed data from the portable terminal 90 in step S402. Subsequently, in step S403, it is determined whether or not the moving speed V represented by the received moving speed data is lower than a set value (for example, 5 km / h).

  When the moving speed or walking speed of the user who carries the mobile terminal 90 is too fast, the measurement timing of the current position of the user and the reception timing from the transmitter 30 are greatly shifted during the search operation by the mobile terminal 90. As a result, a search error may occur. The moving speed V is monitored so that this does not happen.

  If the moving speed V is lower than the set value, the process proceeds to step S404. If the moving speed V is not lower than the set value, the current search is skipped, and the process returns to, for example, step S303.

  Subsequently, in step S404, in the plurality of parking lots 20 represented by the plurality of parking lot data stored in the memory 162, the vicinity of the current position P represented by the current position data received from the mobile terminal 90 (For example, a distance from the current position P is generally a value that is substantially equal to or less than the value R2, but in some cases, a value greater than the value R2 may be Is possible).

  Here, the “current position data” represents the current position of the mobile terminal 90, that is, the longitude and latitude of the current position of the user. The “plurality of parking lot data” represents the parking lot ID and the longitude and latitude of the representative position of the parking lot 20 for each parking lot 20.

  Specifically, the distance between each parking lot 20 and the current position P includes the current position data received from the mobile terminal 90 (the longitude and latitude of the current position) and a plurality of parking lot data stored in the memory 162 (a plurality of parking lot data). And the latitude and longitude of each representative position of the parking lot 20). When there are a plurality of searched parking lots 20, the parking lot 20 closest to the current position P is selected as one target parking lot 20.

  If the search is successful, the process proceeds to step S405. If the search is unsuccessful, the current search is skipped, and the process returns to, for example, step S303.

  In step S <b> 405, one searched target parking lot 20 is a transmitter unique to the transmitter 30 that should be actually installed in the target parking lot 20 in accordance with the conversion table stored in the memory 162. Converted to ID. The transmitter ID is the target transmitter ID. The target transmitter ID is acquired regardless of whether or not the corresponding regular transmitter 30 actually exists in the current target parking lot 20. The conversion table represents a predetermined relationship between the parking lot ID of each parking lot 20 and the transmitter ID of the transmitter 30 that should be actually installed in each parking lot 20.

  As is clear from the above description, the memory 162 has the name of parking lot data, the parking lot ID, and the representative position of the parking lot 20 (this is the transmitter that should be actually installed in the parking lot 20). 30 is equivalent to 30 regular positions), and a predetermined relationship is stored between the parking lot ID of each parking lot 20 and the actual parking lot 20 as the above conversion table. A predetermined relationship is also stored with the transmitter ID of the transmitter 30 that should be.

  Therefore, in the present embodiment, by combining these two relationships, for each transmitter 30, the correspondence between the normal position and the transmitter ID (the above-mentioned “example of transmitter code”) is acquired. Is possible.

  Subsequently, the target transmitter ID is transmitted to the portable terminal 90 in step S406.

  On the other hand, the portable terminal 90 receives the target transmitter ID from the management server 50 in step S306. The received target transmitter ID is stored in the memory 132 of the portable terminal 90.

  Subsequently, similarly to step S113, in step S307, it is determined whether or not the portable terminal 90 has received the identification signal from the transmitter 30 effectively. When the reception intensity of the mobile terminal 90 is equal to or lower than the reference value, it is determined that no identification signal from any transmitter 30 has been received.

  Specifically, the distance between the current transmitter 30 and the portable terminal 90 is measured based on the received identification signal. However, in step S307, unlike step S113, whether or not the distance measurement value is smaller than the effective reception distance R (this time is equal to the value R2), that is, the mobile terminal 90 is currently in the effective reception distance R. It is determined whether or not it is located within a wider effective reception area than when the value is R1.

  In the example shown in FIG. 5, the mobile terminal 90 of the user B exists outside the range of the parking lot 20, but is present within the effective reception area defined by the long effective reception distance R <b> 2, and therefore is identified from the transmitter 30. Receive signals effectively.

  If the distance measurement value is smaller than the effective reception distance R2, it is determined in step S308 that the reception from the transmitter 30 was successful. Subsequently, in step S309, the identification signal received from the current transmitter 30 is converted into an actual transmitter ID.

  Thereafter, in step S310, the actual transmitter ID is compared with the target transmitter ID stored in the memory 132. If the IDs match each other, it is determined in step S311 that the collation has succeeded. This means that the transmitter 30 is present in the current parking lot 20 and that the transmitter 30 is determined to be a legitimate transmitter for the current parking lot 20.

  On the other hand, if the actual transmitter ID and the target transmitter ID do not match each other, it is determined in step S312 that the verification has failed. This means that the transmitter 30 exists in the current parking lot 20, but the transmitter 30 is determined not to be a regular transmitter for the current parking lot 20. In this case, thereafter, in step S313, non-existence determination data indicating that the regular transmitter 30 does not exist in the current parking lot 20 is transmitted to the management server 50 together with the user ID for identifying the current user. .

  The case where the distance measurement value is smaller than the effective reception distance R2 has been described above, but the distance measurement value is not smaller than the effective reception distance R2 (when the portable terminal 90 cannot receive a signal from any transmitter 30) In step S314, it is determined that reception from the transmitter 30 has failed.

  Also in this case, step S313 is subsequently executed. In step S313, as described above, the non-existence determination data indicating that the regular transmitter 30 does not exist in the current parking lot 20 identifies the current actual transmitter ID (or the current parking lot 20). For the parking lot ID) and the user ID for identifying the current user.

  In contrast, in step S407, the management server 50 receives the non-existence determination data from the portable terminal 90 together with the current actual transmitter ID and the current user ID. Subsequently, in step S <b> 408, the current time is measured using the clock 172. Thereafter, in step S409, the history of receiving the absence determination data from the portable terminal 90 is stored in the memory 162 of the management server 50.

  Specifically, for example, as conceptually represented in a tabular form in FIG. 10, each time the presence determination data is received, the event of reception is changed to the reception time and the actual transmitter ID received together. It is recorded in the memory 162 in association with the corresponding parking lot 20 number (or parking lot ID). Only the non-existence determination data received in a predetermined time window (for example, the past 12 hours) is recorded in the memory 162, and the non-existence determination data received in the past from the time covered by the time window is deleted. The As a result, the contents of the memory 162 are updated so that only the non-existence determination data received within the latest predetermined time is always saved.

  Subsequently, in step S410, for example, as shown in FIG. 10, the number of times the presence determination data is received within the time window is recorded in the memory 162 as the absence determination number for each parking lot. In the present embodiment, the absence determination data is defined as data representing provisional absence determination that there is a possibility that there is no valid transmitter 30 in the corresponding parking lot 20, and as a result, The number of absence determinations means the number of times that the provisional absence determination is performed.

  Thereafter, in step S411, for each parking lot, it is determined whether or not the non-existence determination number exceeds a set number (for example, four times). When it exceeds, for example, as shown in FIG. 10, in association with the corresponding parking lot 20, the final absence that the legitimate transmitter 30 does not really exist in the parking lot 20 in the memory 162. The decision is recorded.

  The management server 50 can use the result for various purposes when it is determined that the final absence determination has been performed for any of the parking lots 20.

  In one example, an operator is dispatched to the parking lot 20, and the operator is instructed to visually confirm whether or not the transmitter 30 actually exists in the parking lot 20.

  When the transmitter 30 does not really exist in the parking lot 20, the operator is instructed to install the alternative transmitter 30 at the same place.

  On the other hand, if there is a transmitter 30 in the parking lot 20, the transmitter 30 may be inoperable or malfunctioning for some reason (for example, battery 106 exhaustion, electronic circuit failure, etc.). Judge that there is a suspicion. In this case as well, the operator is instructed to install the alternative transmitter 30 at the same place.

  Thus, according to this embodiment, the operator can remotely monitor the presence / absence of the transmitter 30 and the operation state of the transmitter 30 in each parking lot 20 without visiting the parking lot 20 regularly. .

  Therefore, according to the present embodiment, the number of times the worker is dispatched to each parking lot 20 is reduced, and the effect that the labor cost can be easily reduced can be obtained.

  Furthermore, according to the present embodiment, the possibility that the presence or absence of an abnormality of the transmitter 30 in each parking lot 20 can be discovered earlier than when an operator is regularly dispatched to each parking lot 20, thereby increasing the possibility of It becomes easy to shorten the time during which the transmitter 30 is abnormal in each parking lot 20.

  As is apparent from the above description, in this embodiment, as shown in the functional block diagram of FIG. 11, the computer 134 of the mobile terminal 90 has a plurality of portions.

  Specifically, the portable terminal 90 has the following plurality of parts in order to execute the search mode.

Based on the received identification information, the user is allowed to park in the selected parking lot 20 (step S205).

  Note that at least one of the plurality of portions described above may be partially or wholly realized in the computer 134 of the mobile terminal 90 as long as it is technically established.

  In addition, in some embodiments described above, when the current position of the user is acquired, one parking lot 20 located in the vicinity of the current position is selected and installed in the one parking lot 20.
