Description

[Technical Field]

[0001] The present disclosure relates to a luggage compartment management system. [Background technology]

[0002] In the logistics industry, drivers are often forced to leave their vehicles unlocked in order to reduce delivery times, increasing the risk of items inside being stolen.

[0003] Therefore, it is important to detect suspicious individuals in order to reduce the risk of theft without compromising work efficiency.

[0004] As a system for detecting a suspicious person in a specified area, for example, Patent Document 1 discloses a suspicious person detection system including a probe request detection terminal that detects a probe request sent from a mobile terminal and generates probe information including first identification information unique to the mobile terminal that sent the probe request, and an analysis device that acquires the probe information from the probe request detection terminal and, if the first identification information included in the probe information does not match any of one or more predetermined second identification information, transmits suspicious person information indicating that a suspicious person has been detected to a specified information processing device.

[0005] Patent document 2 also discloses a suspicious person estimation system that includes a mobile phone, a radio wave monitoring device, a monitor control device, and a management server, in which the radio wave monitoring device restores the ID code sent from the mobile phone and transmits the ID code to the management server along with the date and time of reception, and the management server manages the history of the received ID codes for each radio wave monitoring device, the ID code of a mobile phone owned by a suspicious person is designated as a suspicious ID code, and the suspicious ID code is transmitted from the management server to multiple radio wave monitoring devices, and a radio wave monitoring device that detects a suspicious ID code notifies the management server of the detection, and the monitor control device allows the radio wave monitoring device to be registered when installed and the suspiciousness level for the ID code to be input.

[0006] [Patent Document 1] Patent No. 6017004 [Patent Document 2] Patent No. 6799028 Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, if a thief commits a crime with a mobile phone that emits radio waves, this becomes circumstantial evidence that the thief was at the scene of the crime, i.e., that he committed the theft. For this reason, it is unlikely that a thief would commit a crime with a mobile phone in order to avoid circumstantial evidence.

[0008] The technologies described in Patent Documents 1 and 2 above use radio waves emitted from mobile phones to detect and estimate suspicious individuals, and therefore have the problem of being unable to detect suspicious individuals who are not carrying mobile phones.

[0009] An object of the present disclosure is to provide a luggage compartment management system that can manage luggage compartments without impairing work efficiency. [Means for solving the problem]

[0010] In order to achieve the above object, the luggage compartment management system in the present disclosure includes: a radio wave transmitting unit that transmits radio waves carrying identification information; a radio wave sensor for receiving the radio waves; a detection unit that detects that a door that opens and closes an entrance to the luggage compartment has been opened; a storage unit that stores predetermined identification information; an acquisition unit that acquires the intensity of the radio waves received by the radio wave sensor when the door is opened; a determination unit that determines whether or not identification information carried on the radio waves is the predetermined identification information when the intensity of the acquired radio waves exceeds a threshold; Equipped with.

[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 is a functional block diagram showing functions of a luggage compartment management system according to an embodiment of the present disclosure. The luggage compartment management system 100 according to the embodiment of the present disclosure will be described using an example in which the luggage compartment 2 provided in a delivery vehicle 1 is managed. In this case, the luggage compartment 2 is managed by the driver who drives the vehicle 1. The luggage compartment management system 100 may also be applied to cases in which the luggage compartment management system 100 is placed at a logistics base and manages warehouse facilities that store luggage from the time it is received until it is shipped. In the following description, a person who is stored in the memory unit 53 as the person who manages the luggage compartment 2 will be referred to as a "driver" or "registered person," and a person who is not stored in the memory unit 53 will be referred to as a "suspicious person" or "unregistered person."

[0014] 2 is a diagram showing the state of the luggage compartment management system when a luggage compartment door is opened by a suspicious person in an embodiment of the present disclosure. In order to avoid impairing work efficiency, the driver (registered person) may leave the vehicle 1 without locking the door 2a that opens and closes the entrance to the luggage compartment 2. In this case, the suspicious person may be able to open the door 2a of the luggage compartment 2, increasing the risk of theft of luggage in the luggage compartment 2.

[0015] The luggage compartment management system 100 according to the embodiment of the present disclosure determines whether the person opening the door 2a of the luggage compartment 2 is a driver (registered person) or a suspicious person (unregistered person), and if the person is a suspicious person (unregistered person), notifies the driver of the determination result, thereby making it possible to reduce the risk of theft.

[0016] The luggage compartment management system 100 includes a radio wave transmitter 3 and a radio wave sensor 4.

[0017] The radio wave transmitting unit 3 transmits radio waves of a predetermined frequency belonging to a predetermined band. The radio wave transmitting unit 3 holds identification information and transmits radio waves carrying the identification information. The identification information is information used in the determination by the determination unit (522). The identification information is information for verifying that a person who opens the door 2a and attempts to enter the luggage compartment 2 is the driver (registered person), that is, for verifying the legitimacy of the person entering the luggage compartment 2. The radio wave transmitting unit 3 is worn by the driver (registered person). The radio wave transmitting unit 3 transmits radio waves carrying the identification information for identifying the driver. The radio wave transmitting unit 3 is, for example, a smart key.

[0018] The radio wave sensor 4 is disposed inside the luggage compartment 2. The radio wave sensor 4 is disposed in a position where it can receive radio waves transmitted from the radio wave transmitter 3 carried by the driver who opens the door 2a at a radio wave intensity exceeding a threshold. Note that the radio wave sensor 4 may be disposed outside the luggage compartment 2 as long as it can receive radio waves transmitted from the radio wave transmitter 3 at a radio wave intensity exceeding a threshold.

[0019] The luggage compartment management system 100 includes a control device 5, a detection unit 6, and a mobile terminal 7 in addition to the radio wave transmission unit 3 and the radio wave sensor 4 described above.

[0020] The control device 5 is, for example, an in-vehicle system mounted on the vehicle 1, and functions as a communication unit 51, a control unit 52, and a storage unit 53. In FIG. 1, arrows indicate main data flows, and there may be data flows not shown in FIG. 1. In FIG. 1, each functional block indicates a configuration of a function unit, not a configuration of a hardware (device) unit. Therefore, the functional blocks shown in FIG. 1 may be implemented in a single device, or may be implemented separately in multiple devices. Data may be exchanged between functional blocks via any means, such as a data bus.

[0021] The storage unit 53 has a database that can read and write various information. The database is configured with one or more HDDs (Hard Disk Drives), SSDs (Solid State Drives), or the like.

[0022] The memory unit 53 includes a ROM (Read Only Memory) that stores the BIOS (Basic Input Output System) of the computer that realizes the control device 5, a RAM (Random Access Memory) that serves as the working area of ​​the control device 5, an OS (Operating System), application programs, and a HDD that stores data referenced when the application programs are executed.

[0023] The storage unit 53 stores identification information for identifying a driver (registered person). In the following description, the identification information for identifying a driver (registered person) is referred to as driver identification information ID_Driver. The driver identification information ID_Driver corresponds to the "predetermined identification information" of the present disclosure.

[0024] The communication unit 51 has a communication function for connecting to an external network such as the Internet. The communication unit 51 transmits and receives various information to and from the mobile terminal 7 via the Internet. The communication unit 51 transmits information (e.g., a suspicious person detection event) output from the output unit 523 to the mobile terminal 7 via the Internet.

[0025] The detection unit 6 detects that the door 2a has been opened. Specifically, the detection unit 6 is a door opening sensor that detects that the door 2a has been opened when the opening degree of the door 2a exceeds a threshold value. The detection unit 6 may also be a distance sensor that detects that the door 2a has been opened when the door 2a is a predetermined distance away from the sensor. The detection unit 6 may also be a limit switch that turns on when the door 2a is opened and turns off when the door 2a is closed. The detection unit 6 sends the detection result to the control device 5. The acquisition unit 521 acquires the detection result of the detection unit 6.

[0026] The control unit 52 has an acquisition unit 521, a determination unit 522, and an output unit 523. The acquisition unit 521 acquires the detection result of the detection unit 6. The acquisition unit 521 also acquires the radio waves received by the radio wave sensor 4 (radio waves transmitted from the radio wave transmission unit 3).

[0027] FIG. 3 is a diagram illustrating a state of the luggage compartment management system when the luggage compartment door is opened by the driver in an embodiment of the present disclosure. FIG. 3 illustrates a case where, when the driver opens the door 2a, the radio wave transmitter 3 transmits radio waves carrying identification information ID_Driver for identifying the driver, and the radio wave sensor 4 receives the radio waves. Therefore, in this case, the acquisition unit 521 acquires radio waves carrying the identification information ID_Driver for identifying the driver. In contrast, FIG. 2 illustrates a case where, when the door 2a is opened by a suspicious person not wearing the radio wave transmitter 3, the radio waves received by the radio wave sensor 4 are not transmitted from the suspicious person. Therefore, in this case, the acquisition unit 521 does not acquire radio waves.

[0028] The determination unit 522 determines whether the door 2a has been opened based on the detection result of the detection unit 6 acquired by the acquisition unit 521. When the door 2a has been opened, the determination unit 522 determines whether the radio wave intensity of the radio waves received by the radio wave sensor 4 exceeds the threshold value Th_Rfs. When the radio wave intensity of the radio waves received by the radio wave sensor 4 exceeds the threshold value Th_Rfs, the determination unit 522 determines whether the identification information carried on the radio waves is the identification information ID_Driver.

[0029] The output unit 523 outputs the determination result of the determination unit 522. Specifically, as the determination result of the determination unit 522, the output unit 523 outputs information indicating that the door 2a is open or information indicating that the door 2a is closed. Furthermore, the output unit 523 outputs information indicating that the radio wave strength exceeds the threshold value Th_Rfs or information indicating that the radio wave strength is equal to or less than the threshold value Th_Rfs. Furthermore, the output unit 523 outputs information indicating that the identification information is the identification information ID_Driver or information indicating that the identification information is not the identification information ID_Driver (suspicious person detection event).

[0030] The mobile terminal 7 is a terminal device such as a smartphone or tablet terminal carried by the driver (registrant). The mobile terminal 7 receives the determination result of the determination unit 522 from the communication unit 51.

[0031] Next, an example of the operation of the luggage compartment management system 100 according to the embodiment of the present disclosure will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the operation of the luggage compartment management system according to the embodiment of the present disclosure. This flow is started at predetermined time intervals after the start-up switch of the present system is turned on.

[0032] First, in step S100, the acquisition unit 521 acquires the detection result of the detection unit 6.

[0033] Next, in step S110, the determination unit 522 determines whether the door 2a is open. If the door 2a is open (step S110: YES), the process proceeds to step S120. If the door 2a is not open (step S110: NO), the process ends.

[0034] In step S120, the acquisition unit 521 acquires, from the storage unit 53, the identification information ID_Driver of the driver (registrant).

[0035] Next, in step S130, the radio wave intensity of the radio wave received by the radio wave sensor 4 is acquired.

[0036] Next, in step S140, determination unit 522 determines whether the radio wave strength is greater than the threshold (radio wave strength>threshold?). If the radio wave strength exceeds the threshold (step S140: YES), the process proceeds to step S150. If the radio wave strength is equal to or less than the threshold (step S140: NO), the process proceeds to step S170.

[0037] Next, in step S150, the radio wave sensor 4 acquires the identification information carried in the received radio wave.

[0038] Next, in step S160, determination unit 522 determines whether the identification information is ID_Driver. If the identification information is ID_Driver (step S160: YES), this flow ends. If the identification information is not ID_Driver (step S160: NO), the process proceeds to step S170.

[0039] In step S170, the output unit 523 outputs the determination result, and the communication unit 51 transmits the determination result to the mobile terminal 7. After that, this flow ends. This allows the driver to recognize that the door 2a has been opened by a suspicious person.

[0040] The cargo space management system 100 in the above embodiment includes a radio wave transmitting unit 3 that transmits radio waves carrying identification information, a radio wave sensor 4 that receives radio waves, a detection unit 6 that detects that the door 2a that opens and closes the entrance and exit of the cargo space 2 has been opened, a memory unit 53 that stores predetermined identification information, an acquisition unit 521 that acquires the intensity of the radio waves received by the radio wave sensor 4 when the door 2a is opened, and a judgment unit 522 that determines whether the identification information carried in the radio waves is the predetermined identification information when the intensity of the acquired radio waves exceeds a threshold value Th_Rfs.

[0041] With the above configuration, it is possible to determine whether the person who opened the door 2a is the driver (registered person) or a suspicious person (unregistered person), so the driver can continue working while managing the luggage compartment based on the determination result, making it possible to manage the luggage compartment without compromising work efficiency.

[0042] Furthermore, in the luggage compartment management system 100 according to the above embodiment, the radio wave transmitter 3 is portable by the manager who manages the luggage compartment 2, and the identification information carried in the radio waves transmitted by the radio wave transmitter 3 is identification information that identifies the manager. This allows the driver to confirm that a suspicious person other than the driver has opened the door 2a.

[0043] (Variation) Next, a modified example of the embodiment of the present disclosure will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of the operation of a luggage compartment management system in the modified example of the present embodiment. Note that steps S100 to S160 shown in Fig. 5 are the same as steps S100 to S160 shown in Fig. 4.

[0044] In the cargo room management system 100 in the first modification, if the radio wave intensity exceeds the threshold (step S140: YES) and the identification information is ID_Driver (step S160: YES), the process proceeds to step S200. In step S200, the output unit outputs the determination result of the determination unit 522, and the communication unit transmits the determination result.

[0045] In the first modification, the mobile terminal 7 may receive information indicating that the door 2a is open, information indicating that the radio wave intensity exceeds the threshold value Th_Rfs, and information indicating that the identification information is the identification information ID_Driver. In this case, the driver can recognize that the door 2a has been opened by the driver himself. The driver can also recognize that the cargo space management system 100 is operating normally.

[0046] In addition, in the first modification, the mobile terminal 7 may receive information indicating that the door 2a is open, information indicating that the radio wave intensity exceeds the threshold value Th_Rfs, and information indicating that the identification information is not the identification information ID_Driver. In this case, the driver can recognize that the door 2a has been opened by a suspicious person (an unregistered person).

[0047] In addition, in the first modification, the mobile terminal 7 may receive information indicating that the door 2a is closed. In this case, the driver can continue the delivery work while confirming that the door 2a is closed.

[0048] Furthermore, in the luggage compartment management system 100 according to the above embodiment, in addition to the driver, a delivery assistant may ride in the vehicle 1 as a manager. In this case, identification information ID_Driver2 that identifies the delivery assistant is stored in the storage unit 53. Then, the mobile terminal 7 may receive information indicating that the identification information is identification information ID_Driver2. In this case, the driver can recognize that the door 2a has been opened by the delivery assistant. Furthermore, the driver can recognize that the luggage compartment management system 100 is operating normally.

[0049] Furthermore, the above-described embodiments are merely examples of specific embodiments for carrying out the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited by these embodiments. In other words, the present disclosure can be carried out in various forms without departing from its gist or main features. [Industrial Applicability]
