  Hereinafter, an empty parking space guidance support system according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an overall view showing a basic configuration of an empty parking space guidance support system according to a first embodiment of the present invention including a service area of a parking lot 101. In this empty parking space guidance support system, a plurality of parking spaces having a plurality of parking lanes are divided into a plurality of predetermined areas in the parking lot 101 including the entrance 117 and the exit 122 of the jurisdiction (in FIG. 1, A parking lane and B parking lane A second parking space having a C parking lane and a D parking lane, a third parking space having an E parking lane and an F parking lane, and a fourth having a G parking lane and an H parking lane. And a monitoring device 123 such as a camera or a sensor that monitors the entire service area of the user's car 116 entering the parking lot 101 from the entrance 117. An empty parking space guidance support function unit 120 in the server 115 received via the network 114 allows each parking space to be parked. Shortest vacant parking space 119 contained in the lane (in FIG. 1 is included is in the A parking lane of the first parking space) is to induce the car 116 to the. However, the empty parking space guidance support function unit 120 here lights up installed along the extending direction of each parking lane when the vehicle 116 is routed to the empty parking space 119 according to the shortest route in the parking lot 101. Each route arrow portion 118 to be controlled has a function of instructing the lamp lighting control device 121 which is a lighting control means via the network 114 to turn on and guide the one corresponding to the guide route, In addition to having the function of turning off the light, it has a function of enabling route guidance according to the use frequency of the user based on past parking history information.

  More specifically, the empty parking space guidance support function unit 120 registers, as various functional units, parking history information when the user's car 116 enters and leaves each parking lane in each parking space. The entry / exit function unit 102 that performs the process 102a and the entrance route 117 of the user's car 116 to the entrance 117 of the parking lot 101 determine the optimum parking location based on the parking history information and provide a guide route to the optimum parking location. The stoppage location determination function unit 103 that performs the stoppage location determination processing 103a to be acquired and the shortest to the shortest of the free parking spaces 119 based on the full availability of each parking lane in each parking space acquired in real time The shortest route discriminating function unit 104 that performs the shortest route discriminating process 104a for discriminating the route, and the shortest of the target empty parking space 119 based on the guidance route A guidance function unit 105 that performs a guidance process 105a that guides the route of the user's car 116 according to the shortest route to the one, and an exit function unit 106 that performs an exit process 106a that deletes the guidance route used after the route guidance. In this case, the entrance stop location determination processing unit 103a of the entrance stop location determination function unit 103 instructs the lamp lighting control device 121 via the network 114 to correspond to the guide route in each route arrow portion 118. The guidance function 105a of the guidance function unit 105 instructs the lamp lighting control device 121 via the network 114 to guide the user's car 116 by turning on the one to be operated. Responsible for extinguishing what the user's car has passed.

  In addition, the empty parking space guidance support function unit 120 includes various tables as individual tables for holding parking / vacant state information for each parking space, and whether parking is possible for each parking lane in each parking space. A lane availability determination table 108 to be held, a parking history table 109 for identifying a user's car 116 by number and holding a history of parking for each parking lane in each parking space as parking history information, and route guidance The shortest route guidance work table 110 that holds the guidance route to the shortest route and the passing state information, and the lane that sets which empty portion is to be preferentially guided when there are a plurality of locations in each parking lane The priority master table 111 and the shortest route master table for setting the shortest route in each parking lane And Le 112, and a separate parking space priority master table 113 for setting the priority of the vacant parking space to induce in each parking lane, a. Incidentally, among the functions of the above-described vacant parking space guidance support function unit 120, the entrance stop location discriminating function unit 102 stores the guide route acquired by the entrance stop location discriminating process 102a in the shortest route guidance work table 110. . Further, the guidance function unit 105 performs route guidance with reference to the passing state information acquired from the shortest route guidance work table 110 by the guidance processing 105a. Further, the exit function unit 106 deletes the guide route in the shortest route guide work table 110 by the exit processing 106a after route guide.

  In this empty parking space guidance support system, when the user's car 116 passes through the entrance 117 of the parking lot 101, an identification number (number) is stored in the server 115 from the monitoring device 123 using cameras and sensors covering the entire area through the network 114. To the empty parking space guidance support function unit 120. Therefore, in the empty parking space guidance support function unit 120, the entrance stop location discrimination function unit 102 performs the entrance stop location discrimination process 102a to acquire the guidance route, and the shortest route discrimination function unit 103 performs the shortest route discrimination process. Since the shortest route is calculated by performing 103a, the lamp lighting control device 121 is instructed to light all the route arrow portions 118 corresponding to the guidance route leading to the shortest route, and the lamp lighting control device 121 corresponds to the corresponding route. All of the arrow portions 118 are turned on. During the guidance, the identification number (number) of the route arrow part 118 is transmitted to the empty parking space guidance support function part 120 through the network 114 when the route 116 passes through the car 116, so that the guidance process 104a in the guidance function part 104 is performed. Thus, the control for turning off the route arrow portion 118 that has passed is performed through the lamp lighting control device 121. Further, when entering / exiting the target empty parking space 119, the parking lane / space / identification number (number) is transmitted to the empty parking space guidance support function unit 120 through the network 114, so the entry / exit function unit 104 performs the entry / exit processing. 104a is performed and the parking history information is updated. Further, when the user's car 116 passes through the exit 122, the identification number (number) is transmitted to the empty parking space guidance support function unit 120 through the network 114, so that the exit function unit 106 performs the exit process 106a and performs the shortest processing. The guide route in the shortest route guide work table 110 used after the route guide to the route is deleted (cleared).

  FIG. 2 is a flowchart showing an operation process related to the stoppage time determination process 102a at the time of entry by the stoppage position determination function part 102 at the time of entry provided in the empty parking space guidance support function part 120 in the server 115.

  In the entry stop position determination process 102a, when the user's car 116 enters the entrance 117 of the parking lot 101, the number transmitted by the monitoring device 123 covering all areas is stored in the number (variable) (step S201). ) After performing the processing, as the parking history determination processing, it is determined whether or not there is a car number that has entered the parking history table 109 with reference to the parking history table 109 (step S202). As a result of this determination, if there is no number of the car 116 that has entered (if there is no parking history), the process proceeds to the shortest distance discrimination process 103a by the shortest distance discrimination function unit 103. Is present (if the number of parking histories is one or more), the history number information acquired from the parking history table 109 is stored in the parking history list (variable) (step S203). Loop start for minute loop: cot = 0, parking history list. Length-1, 1 (step S204) is set. Incidentally, the parking history list here includes the number of parkings confirmed based on the number of the car 116 of the user, the (parking) lane, the stop date and time, and the departure date and time.

  Next, as a parking lane empty state determination process, it is determined whether or not the parking lane acquired from the parking history list is empty with reference to the lane empty state determination table 108 (step S205). If the parking lane is not free as a result of this determination, the next parking lane is confirmed until the number of loops reaches the number of parking history lists, and loop start: cot = 0, parking history list. The setting of length-1, 1 (step S204) and the determination of whether or not the parking lane is free (step S205) are repeated, and when the number of parking history lists is reached, the loop ends (step S206) and the shortest distance The process proceeds to the shortest distance determination process 103a by the determination function unit 103. If the parking lane is empty, the parking lane (parking history list) is stored in order to exit the loop and store the corresponding parking lane in the empty lane (variable). In order to store the corresponding shortest route in the variable after storing the parking lane acquired from the variable “empty lane” (step S207), the route information to the empty lane acquired from the shortest route master table 111 is stored. The process of storing in the shortest path list (step S208) is performed. Incidentally, the shortest route list here includes the shortest empty parking lane, the guidance of the route arrow portion 118, and the order of movement.

  Further, after performing a process of adding a record to the shortest route guidance work table 110 based on the variable of the shortest route list (step S209), ON information is transmitted to the lamp lighting control device 121 based on the variable of the shortest route list. (Step S210) The process is ended after all the target route arrow portions 118 are turned on by performing the process.

  FIG. 3 is a flowchart showing an operation process related to the guidance process 105 a by the guidance function unit 105 provided in the empty parking space guidance support function unit 120 in the server 115.

  In the guidance process 105a, the number transmitted from the monitoring device 123 covering the entire area after the user's car 116 enters the entrance 117 of the parking lot 101 is stored in the number (variable) (step S301). After that, the passage information transmitted by the arrow sensor installed in the route arrow portion 118 is acquired (step S302), and the passage route arrow stored in the variable is obtained.

  Next, referring to the shortest route guidance work table 110, the passing state of the shortest route guidance work table 110 is stored in the variable “passing state” (step S303). As processing, it is determined whether or not the passage has been completed (step S304). If the result of this determination is that it has already passed, the process of transmitting the OFF information to the lamp lighting control device 121 (step S312) is performed to turn off the route arrow portion 119 that has passed, and then the operation process ends. If not already passed, it is determined whether or not the vehicle is passing (step S305) as the second passage determination process. If the result of this determination is that the route arrow is not passing, the route arrow (head) of the shortest route guidance work table 110 is acquired and stored in the variable “route arrow” (step S306). As the arrow determination process, the route arrow here is compared with the passing route arrow acquired in the process of acquiring the previous passing information (step S302), and it is determined whether or not the passing route arrow matches the route arrow ( Step S307) is performed. If the result of this determination is that they match, the shortest route guidance work table 110 is updated based on the variable number and the route arrow (step S308), and the passing state of the shortest route guidance work table 110 is passed. After updating, the process of transmitting the OFF information to the lamp lighting control device 121 (step S312) is performed and the route arrow part 119 that has passed through is turned off, and the operation process is terminated. Since it can be considered that the route is different from the route, the guidance is canceled as error processing.

  By the way, as a result of the determination (step S305) as to whether or not the vehicle is passing, which is the previous second passage determination process, the route arrow (not passing) of the shortest route guidance work table 110 is acquired. Is stored in the variable “route arrow” (step S309) to obtain a route arrow, and as the route arrow determination process, the route arrow and the previous passage information are acquired (step S302). The passing route arrow is compared to determine whether the passing route arrow matches the route arrow (step S310). If the result of this determination is that they match, the shortest route guidance work table 110 is updated based on the variable number and the route arrow (step S311), and the passing state of the shortest route guidance work table 110 is passed. After updating, the process of transmitting OFF information to the lamp lighting control device 121 (step S312) is performed and the route arrow part 119 that has passed through is turned off, and the operation process is terminated. In the same way as in this case, it can be considered that the route is different from the guidance, so the guidance is canceled as error processing.

  FIG. 4 is a flowchart showing an operation process related to the shortest path determination process 103 a of the shortest path determination function unit 103 provided in the empty parking space guidance support function unit 120 in the server 115.

  In the shortest path determination process 103a, the lane priority master table 111 and the lane empty state determination table 108 are stored with reference to the lane priority master table 111 and the lane empty state determination table 108. After performing the process of storing the empty lane information acquired from the variable “empty lane list” (step S401), it is determined whether the number of empty lanes is zero (step S402) as the empty lane number determination process. . If the number of empty lanes is zero as a result of this determination, the vehicle is full and error processing is performed to stop guidance. If the number of empty lanes is not zero (if there is one or more empty), loops are made for the number of empty lanes. Start loop: cot = 0, empty lane list. After setting length-1, 1 (step S403), referring to the shortest route guidance work table 110 and the individual parking table 107, it is confirmed whether an empty lane is already being guided (step S404), and the guidance state is set. Is stored in the variable “guidance state”, and based on the variable “guidance state”, as an empty lane guidance determination process, it is determined whether or not an empty lane is already being guided (step S405). If the result of this determination is that guidance is in progress, the next empty lane is confirmed until the number of loops reaches the number of empty lane lists, and loop start: cot = 0, empty lane list. The setting of length-1, 1 (step S403), the process of confirming whether the empty lane is already being guided (step S404), and the determination whether the empty lane is already being guided (step S405) are repeated. After the end of the loop when the number of lists is reached (step S406), the shortest route guidance work table 110 is updated based on the variable “empty lane list” in the same way as when the empty lane is not being guided and exits the loop. (Step S407) is performed to register the guide route in the shortest route guide work table 110, and the operation process is terminated.

  FIG. 5 is a flowchart showing an operation process related to the entry / exit processing 104 a of the entry / exit function unit 104 provided in the empty parking space guidance support function unit 120 in the server 115.

  In the entry / exit process 104a, the entry / exit information is acquired by the sensor installed in the empty parking space 119 (step S501), is stored in the variable “entry / exit information”, and then transmitted by the monitoring device 123 that covers all areas. The number that has been stored is stored in a number (variable) (step S502).

  Next, after performing the process of updating the individual parking table 107 based on the variable number and the entry / exit information (step S503), the lane availability determination table 108 is updated based on the individual parking table 107 and the variable “number”. After performing the process (step S504), the operation process is terminated.

  FIG. 6 is a flowchart showing an operation process related to the exit process 106 a of the exit function unit 106 provided in the empty parking space guidance support function unit 120 in the server 115.

  In the exit process 106a, when the user's car 116 reaches the exit 122 of the parking lot 101, the number transmitted by the monitoring device 123 covering the entire area is stored in the number (variable) (step S601). After performing, the process which deletes all the records corresponding to the number (variable) from the shortest route guidance work table 110 (step S602) is performed, and then the operation process is ended.
