[0011] EMBODIMENT 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an example of the configuration of the wearing determination system 100 according to the first embodiment of the present invention. As shown in FIG. 1, the wearing determination system 100 includes helmets 200_1, . . . 200_n (n is a positive integer) as one or more wearing members, and a wearing determination device 300. Hereinafter, when the helmets 200_1, . . . 200_n are not particularly distinguished from each other, they will be simply referred to as "helmets 200". The helmet 200 has a communication function, and the helmet 200 and the wearing determination device 300 are capable of communicating with each other via a network N. The wearing determination device 300 may also be capable of communicating with a portable information terminal (not shown) carried by a person wearing the helmet 200 via the network N. The wearing determination system 100 determines whether or not a person is properly wearing the helmet 200 in an environment where one or more people need to wear the helmet 200, for example, a work site such as a construction site.

[0012] Fig. 2 shows an example of the configuration of the helmet 200 according to the first embodiment of the present invention. As shown in Fig. 2, the helmet 200 includes a sensor 210, a GNSS (Global Navigation Satellite System) receiving unit, a notification unit 230, a communication unit 240, and a control unit 250. The configuration of the helmet 200 including each functional block of the control unit 250 shown in Fig. 2 may be provided entirely in the helmet 200, or an information terminal (not shown) carried by the person wearing the helmet 200 may include some of the configuration. When some of the configuration is provided in an information terminal carried by the person wearing the helmet 200, the helmet 200 and the information terminal are connected wirelessly or by wire.

[0013] The sensor 210 detects the wearing state of the helmet 200. Specifically, the sensor 210 is, for example, a sensor that detects that a connecting member such as a buckle that connects a chin strap of the helmet 200 is connected. The sensor 210 is also, for example, a gyro sensor that detects the inclination of the helmet 200. The sensor 210 is also, for example, a gyro sensor that detects the swinging of the helmet 200.

[0014] The GNSS receiver 220 receives signals from positioning satellites. The GNSS receiver 220 may be provided in the helmet 200, or in a portable information terminal (not shown) carried by a person wearing the helmet 200, or may be provided in both the helmet 200 and the information terminal.

[0015] The notification unit 230 is controlled by a notification control unit 253 (described later) of the control unit 250, and issues a predetermined notification. The notification unit 230 is provided with, for example, a speaker, and issues the predetermined notification by voice. The notification unit 230 may also be provided with a display unit such as a liquid crystal panel, and display the predetermined notification. Here, the predetermined notification is, for example, a message such as "Please wear your helmet properly." The notification unit 230 may also be provided with a motor or the like that vibrates the helmet 200, and issue the predetermined notification by vibration. The notification unit 230 may be provided in the helmet 200, or may be provided in a portable information terminal (not shown) carried by the person wearing the helmet 200.

[0016] The communication unit 240 is controlled by a communication control unit 254 (described later) of the control unit 250, and performs communication between the helmet 200 and the wearing determination device 300. The communication unit 240 is a communication module that performs communication using any communication method such as Bluetooth (registered trademark). Specifically, the communication unit 240 transmits information regarding the state of the helmet 200 to the wearing determination device 300. Here, the information regarding the state of the helmet 200 includes information regarding the wearing state of the helmet 200 and information regarding the position of the helmet 200. Furthermore, the information regarding the wearing state of the helmet 200 includes, for example, information regarding whether or not the chin strap of the helmet 200 is connected, the tilt direction and tilt angle of the helmet 200, and whether or not the helmet 200 is swinging. Furthermore, the communication unit 240 receives a notification control signal (described later) transmitted from the wearing determination device 300. The communication unit 240 may be provided in the helmet 200, or may be provided in a portable information terminal (not shown) carried by a person wearing the helmet 200.

[0017] The control unit 250 is a control device that executes various processes in the helmet 200, and is composed of, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), etc. The control unit 250 includes a sensor information acquisition unit 251, a position information calculation unit 252, a notification control unit 253, and a communication control unit 254 as functional blocks that are realized by the CPU executing various programs stored in the ROM, etc.

[0018] The sensor information acquisition unit 251 acquires the detection value of the sensor 210, and generates information regarding the wearing state of the helmet 200 based on the detection value. For example, the sensor information acquisition unit 251 generates information regarding whether or not the chin strap of the helmet 200 is connected. The sensor information acquisition unit 251 also generates information regarding the tilt direction and tilt angle of the helmet 200. The sensor information acquisition unit 251 also generates information regarding whether or not the helmet is swinging.

[0019] The position information calculation unit 252 calculates information relating to the position of the helmet 200 based on the signal received by the GNSS receiving unit 220.

[0020] When the notification control unit 253 receives a notification control signal from the wearing determination device 300 via the communication unit 240, it controls the notification unit 230 to perform a predetermined notification.

[0021] The communication control unit 254 controls the communication unit 240 to control communication of the helmet 200. For example, the communication control unit 254 controls the communication unit 240 so as to transmit information related to the state of the helmet 200 to the wearing determination device 300. In addition, the communication control unit 254 controls the communication unit 240 so as to receive a notification control signal transmitted from the wearing determination device 300.

[0022] The wearing determination device 300 is an information terminal such as a PC connected to the network N, or a server device. The wearing determination device 300 is, for example, an information terminal or server device used by a business operator who works in a place where the helmet 200 is required to be worn, or a server device used by a business operator who provides a service providing wearing information of the helmet 200 to a business operator who works in a place where the helmet 200 is required to be worn. As shown in FIG. 1, the wearing determination device 300 includes a control unit 310, a storage unit 320, a display unit 330, and a communication unit 340.

[0023] The control unit 310 is a control device that executes various processes in the wearing determination device 300, and is composed of, for example, a CPU, a ROM, and a RAM. The control unit 310 includes a state determination unit 311, a wearing determination unit 312, a notification control unit 313, and a communication control unit 314 as functional blocks realized by the CPU executing various programs stored in the ROM or the like. The storage unit 320 also stores map information 321 and the like.

[0024] The state determination unit 311 determines whether or not the person wearing the helmet 200 is in a state where it is required to wear the helmet 200. Specifically, the state determination unit 311 refers to the map information 321 stored in the storage unit 320, and determines whether or not the person is in a state where it is required to wear the helmet 200, based on the position of the helmet 200 or the person. In this case, the state where it is required to wear the helmet 200 is determined to be whether or not the position of the helmet 200 or the person is located in a range where it is required to wear the helmet 200.

[0025] The map information 321 referred to by the state determination unit 311 is information indicating an area or section where the helmet 200 is required to be worn, and an area or section where the helmet 200 is not required to be worn. The area or section where the helmet 200 is required to be worn is, for example, an area or section where a person works, an area or section where a dangerous object exists, etc. The area or section where the helmet 200 is not required to be worn is, for example, a rest space, etc. Such an area or section is set by a business operator or the like who works in a place where the helmet 200 is required to be worn. Information regarding the position of the person may be transmitted to the wearing determination device 300 from an information terminal carried by the person.

[0026] The state determination unit 311 may determine whether or not it is a state requiring the wearing of the helmet 200 based on time. For example, in a specific section, when work requiring the wearing of the helmet 200 is performed from 09:00 to 14:00, and wearing of the helmet 200 is not required during other periods, it determines whether or not it is a state requiring the person to wear the helmet 200 based on the time in addition to the position of the helmet 200 or the person.

[0027] The wearing determination unit 312 determines whether or not a person wearing the helmet 200 is properly wearing the helmet 200. Specifically, the wearing determination unit 312 determines whether or not a person wearing the helmet 200 is properly wearing the helmet 200, based on information related to the wearing state of the helmet 200 transmitted from the helmet 200.

[0028] Here, the following three conditions are given as examples of conditions for determining that the helmet 200 is properly worn. Condition A: The chin strap of the helmet 200 is connected. Condition B: The tilt of the helmet 200 in the front-to-back direction is within ±45° from the reference position, and the tilt in the left-to-right direction is within ±30° from the reference position. Condition C: The helmet 200 is swaying. When all of conditions A, B, and C are satisfied, the wearing determination unit 312 determines that the person is wearing the helmet 200 properly. Note that even if condition B is not satisfied temporarily, for example, within 5 seconds, the wearing determination unit 312 does not have to determine that the person is not wearing the helmet 200 properly. Furthermore, condition C is a condition for eliminating cases where the person is not wearing the helmet 200 and has placed it somewhere, even if conditions A and B are satisfied. Furthermore, the tilt direction and angle of condition B are merely examples and are not limiting.

[0029] The notification control unit 313 performs a predetermined notification when a person is in a state where it is required to wear the helmet 200, but the person is not wearing the helmet 200 properly. In other words, the notification control unit 313 performs a predetermined notification when the state determination unit 311 determines that the person is in a state where it is required to wear the helmet 200 because the person is in a range or area where it is required to wear the helmet 200, and the wearing determination unit 312 determines that the person is not wearing the helmet 200 properly. Specifically, the notification control unit 313 performs a predetermined notification in at least one of the helmet 200 and the wearing determination device 300. More specifically, the notification control unit 313 inputs a transmission request instruction of a notification control signal to the communication control unit 314 so that the communication unit 340 transmits a notification control signal to the helmet 200. This allows the notification control unit 313 to cause the helmet 200 to perform a predetermined notification. The notification control unit 313 also controls the display unit 330 of the wearing determination device 300 to perform a predetermined notification.

[0030] The communication control unit 314 controls the communication unit 340 to control the communication of the wearing determination device 300. For example, the communication control unit 314 controls the communication unit 340 so as to receive information relating to the state of the helmet 200 transmitted from the helmet 200. The communication control unit 314 also controls the communication unit 340 so as to transmit a notification control signal to the helmet 200. The communication control unit 314 may also receive information relating to the state of a person from an information terminal carried by the person by controlling the communication unit 340. Here, the information relating to the state of the person includes information relating to the position of the person.

[0031] The display unit 330 is, for example, a liquid crystal display or the like, and displays a predetermined notification according to a control signal input from the notification control unit 313. The display unit 330 is preferably provided at a position where a manager of an employer who works at a place where wearing the helmet 200 is required can check it. The display unit 330 displays, for example, the unique number of the helmet 200 that is not worn properly, the name of a person linked to the unique number of the helmet 200, or the like, as the predetermined notification. The display unit 330 may also display the position information of the helmet 200 on a map based on the map information 321 stored in the storage unit 320, as well as the unique number of the helmet 200, the name of a person linked to the unique number of the helmet 200, or the like.

[0032] The communication unit 340 is controlled by the communication control unit 314, and performs communication between the wearing determination device 300 and the helmet 200. Specifically, the communication unit 340 receives information relating to the state of the helmet 200 transmitted from the helmet 200. The communication unit 340 also transmits a notification control signal to the helmet 200. The communication unit 340 may also receive information relating to the state of a person from an information terminal carried by the person.

[0033] Next, a wearing determination method performed by the wearing determination system 100 according to the first embodiment will be described with reference to FIG. First, the wearing determination device 300 starts acquiring information from the helmet 200. Specifically, in the helmet 200, the sensor information acquisition unit 251 starts generating information related to the state of the helmet 200, and the position information calculation unit 252 starts calculating information related to the position of the helmet 200. Then, the wearing determination device 300 starts receiving information related to the state of the helmet 200 and information related to the position of the helmet 200 from the helmet 200 (step S101). The process of step S101 may start acquiring information from the helmet 200 by issuing an instruction to the helmet 200 present in the range managed by the wearing determination device 300 to start transmitting information related to the state of the helmet 200 and information related to the position of the helmet 200. The transmission of information from the helmet 200 and the reception of information from the helmet 200 by the wearing determination device 300 are continued until the process of FIG. 3 is completed.

[0034] Next, the state determination unit 311 determines, based on the position of the helmet 200 or the position of the person wearing the helmet 200, whether or not the position of the helmet 200 or the person is in a position where it is required to wear the helmet 200 (step S102).

[0035] In step S102, if the state determination unit 311 determines that the position of the helmet 200 or the person is not a position where it is required to wear the helmet 200 (step S102; No), the process proceeds to step S105.

[0036] In step S102, if the state determination unit 311 determines that the position of the helmet 200 or the person is a position where the helmet 200 is required to be worn (step S102; Yes), the wearing determination unit 312 determines whether the person is wearing the helmet 200 properly (step S103).

[0037] In step S103, when the wearing determining unit 312 determines that the person is wearing the helmet 200 appropriately (step S103; Yes), the process proceeds to step S105.

[0038] In step S103, when the wearing determination unit 312 determines that the person is not wearing the helmet 200 properly (step S103; No), the notification control unit 313 performs a predetermined notification in the target helmet 200 (step S104). Note that the notification control unit 313 may perform the predetermined notification in the wearing determination device 300.

[0039] Next, the wearing determination device 300 determines whether or not to end the wearing determination method (step S105).

[0040] In step S105, when the wearing determination device 300 determines not to end the implementation of the wearing determination method (step S105; No), the process returns to step S102.

[0041] In step S105, when the wearing determination device 300 determines that the wearing determination method is to be ended (step S105; Yes), this process ends.

[0042] In addition, while the processing shown in FIG. 3 is being performed, the display unit 330 of the wearing determination device 300 constantly displays information indicating the wearing status of the helmet 200, in addition to information indicating whether the position of the helmet 200 to be managed or the person in question is in a position where the helmet 200 is required to be worn.

[0043] According to the above-described wearing determination system 100 and wearing determination method according to the first embodiment, the sensor 210 provided in the helmet 200 detects that a connecting member such as a buckle that connects the chin strap of the helmet 200 has been connected, and detects the inclination and swing of the helmet 200. The position of the helmet 200 is calculated based on a signal received by the GNSS receiving unit 220. Then, the state determination unit 311 determines whether or not the person is in a state in which it is required to wear the helmet 200 based on information on the position of the helmet 200. The wearing determination unit 312 determines whether or not the person is properly wearing the helmet 200 based on information on the wearing state of the helmet 200 generated based on the detection value of the sensor 210. The notification control unit 313 issues a predetermined notification when the person is in a state in which it is required to wear the helmet 200 and the person is not properly wearing the helmet 200. Therefore, it is not necessary to photograph the head wearing the helmet 200 by the camera, and it is possible to solve the problem that the wearing state of the helmet 200 can be determined only at the location where the camera is installed. In addition, it is possible to solve the problem that it may not be possible to properly determine from the image whether the chin strap is properly attached or not. Therefore, it is possible to properly detect whether the helmet 200 is being worn and to provide a notification.

[0044] EMBODIMENT 2 Next, a helmet 200A as a wearing determination device according to a second embodiment of the present invention will be described. Fig. 4 shows an example of the configuration of the helmet 200A according to the second embodiment. The helmet 200A according to the second embodiment differs from the helmet 200 according to the first embodiment in that it does not include a communication unit 240 and a communication control unit 254, but includes a state determination unit 255 and a wearing determination unit 256. In addition, the processing of the notification control unit 253A according to the second embodiment differs from that of the notification control unit 253 according to the first embodiment. Therefore, among the configuration of the helmet 200A according to the second embodiment, the same configuration as that of the helmet 200 according to the first embodiment is assigned the same reference numerals, and the description thereof will be omitted.

[0045] The helmet 200A according to the second embodiment judges whether or not the person is wearing the helmet 200A appropriately by itself. The helmet 200A is, for example, a helmet worn by a person riding a motorbike, a motorcycle, or the like. The helmet 200A judges whether or not the person is in a state where it is required to wear the helmet 200 based on the position of the helmet 200A or the position of the person wearing the helmet 200A. Note that the helmet 200A includes a communication unit 240 and a communication control unit 254, as in the first embodiment, and may communicate with an information terminal (not shown) carried by the person wearing the helmet 200A or an external server via a network N, and may perform distributed processing of functions.

[0046] The state determination unit 255 determines whether or not the person wearing the helmet 200A is in a state where it is required for the person wearing the helmet 200A to wear the helmet 200A, in other words, whether or not the person wearing the helmet 200A is in a position where it is required for the person wearing the helmet 200A to wear the helmet 200A, based on the position of the helmet 200A. Specifically, when the position of the helmet 200A is on a roadway, the state determination unit 255 determines that the person is in a state where it is required for the person to wear the helmet 200A. The state determination unit 255 determines whether or not the position of the helmet 200A is on a roadway by referring to the map information 261 stored in the storage unit 260 of the helmet 200A. The map information 261 is, for example, map information acquired from a GNSS positioning satellite. Note that the helmet 200A may acquire the map information from an information terminal carried by the person wearing the helmet 200A.

[0047] The wearing determination unit 256 determines whether or not the person is properly wearing the helmet 200 based on the same conditions as those of the wearing determination unit 312 according to the embodiment 1. Here, as described below, only the condition C according to the embodiment 2 is different from the condition C in the embodiment 1. Condition C: The vibration detected by the gyro sensor of the sensor 210 does not include any component higher than a predetermined frequency. Condition C is a condition for determining whether the detected rocking motion is not rocking motion including high frequency components associated with driving a moped or motorcycle, but rocking motion caused by the movement of a person wearing helmet 200A, or rocking motion including high frequency components associated with driving a moped or motorcycle transmitted through a person. That is, condition C is intended to exclude cases where helmet 200A is placed on the rear or case of a moped or motorcycle while conditions A and B are satisfied.

[0048] The notification control unit 253A controls the notification unit 230 to give a predetermined notification when the person is required to wear the helmet 200A and the person is not wearing the helmet 200A properly. Specifically, the notification control unit 253A causes the notification unit 230 to give a predetermined notification by voice. The notification control unit 253A may also cause the display unit (liquid crystal panel or the like) that is the notification unit 230 to display a predetermined notification. Here, the predetermined notification is, for example, a message such as "Please wear your helmet properly." The notification control unit 253A may also cause the notification unit 230 to give a predetermined notification by vibration. The notification unit 230 may also include a light emitting unit, and the notification control unit 253A may cause the notification unit 230 to give a predetermined notification by emitting light. In this case, it is possible to know from the outside that the helmet 200A is not worn properly.

[0049] Next, a wearing determination method implemented by the helmet 200A according to the second embodiment will be described with reference to FIG. First, the state determination unit 255 determines, based on the position of the helmet 200A, whether or not the position of the helmet 200A is a position in which it is required to wear the helmet 200A (step S201).

[0050] In step S201, when the state determination unit 255 determines that the position of the helmet 200A is not a position in which it is required to wear the helmet 200A (step S201; No), the process proceeds to step S204.

[0051] In step S201, if the state determination unit 255 determines that the position of the helmet 200A is a position where the helmet 200A is required to be worn (step S201; Yes), the wearing determination unit 256 determines whether the person is wearing the helmet 200A properly (step S202).

[0052] In step S202, when the wearing determining unit 256 determines that the person is wearing the helmet 200A appropriately (step S202; Yes), the process proceeds to step S204.

[0053] In step S202, when the wearing determination unit 256 determines that the person is not wearing the helmet 200A properly (step S202; No), the notification control unit 253A performs a predetermined notification in the helmet 200A (step S203).

[0054] Next, the helmet 200A determines whether or not to end the implementation of the wearing determination method (step S204).

[0055] In step S204, when the helmet 200 determines not to end the implementation of the wearing determination method (step S204; No), the process returns to step S201.

[0056] In step S204, when the helmet 200 determines that the implementation of the wearing determination method is to be ended (step S204; Yes), this process is ended.

[0057] According to the helmet 200A and the wearing determination method according to the second embodiment described above, as with the wearing determination system 100 and the wearing determination method according to the first embodiment, there is no need to photograph the head wearing the helmet 200A by a camera from outside the vehicle, and the problem that the wearing state of the helmet 200A can be determined only at the location where the camera is installed can be solved. In addition, it is possible to solve the problem that it may not be possible to properly determine whether the chin strap is properly worn from the image. Therefore, it is possible to properly detect the wearing of the helmet 200A and to notify it.

[0058] EMBODIMENT 3 Next, a helmet 200B as a wearing determination device according to a third embodiment of the present invention will be described. Fig. 6 shows an example of the configuration of the helmet 200B according to the third embodiment. The helmet 200B according to the third embodiment differs from the helmet 200A according to the second embodiment in that it does not include a memory unit 260 and map information 261. In addition, the processing of the state determination unit 255B according to the second embodiment differs from that of the state determination unit 255 according to the second embodiment. Therefore, among the configuration of the helmet 200B of the third embodiment, the same configuration as that of the helmet 200A of the second embodiment is assigned the same reference numerals, and the description thereof will be omitted.

[0059] The helmet 200B according to the third embodiment determines whether or not a person is wearing the helmet 200B appropriately by itself. The helmet 200B is, for example, a helmet worn by a person riding a bicycle. The helmet 200B determines whether or not the person is in a state where it is required to wear the helmet 200B based on the moving speed of the helmet 200B. Note that the helmet 200B includes a communication unit 240 and a communication control unit 254, as in the first embodiment, and may communicate with an information terminal (not shown) carried by the person wearing the helmet 200B or an external server via the network N, and may perform distributed processing of functions.

[0060] The state determination unit 255B determines whether or not the person wearing the helmet 200B is in a state where it is required that the person wearing the helmet 200B wears the helmet 200B, based on the moving speed of the helmet 200B. Specifically, the state determination unit 255B calculates the moving speed of the helmet 200B based on the change over time in the position of the helmet 200B. Then, when the moving speed of the helmet 200B is equal to or higher than a predetermined speed, the state determination unit 255B determines that the person is in a state where it is required that the person wears the helmet 200B. Here, the predetermined speed is, for example, a speed faster than the moving speed by walking, such as 10 km / h.

[0061] Next, a wearing determination method performed by the helmet 200B according to the third embodiment will be described with reference to Fig. 7. The processing of steps S302 to S304 shown in Fig. 7 is similar to the processing of steps S202 to S204 shown in Fig. 5, and therefore description thereof will be omitted.

[0062] First, the state determination unit 255B determines, based on the change over time in the position of the helmet 200B, whether the movement speed of the helmet 200B is a movement speed at which it is required to wear the helmet 200B, in other words, whether it is equal to or greater than a predetermined speed (step S301).

[0063] In step S301, when the state determination unit 255B determines that the moving speed of the helmet 200B is not a moving speed at which it is required to wear the helmet 200B (step S301; No), the process proceeds to step S304.

[0064] In step S301, if the state determination unit 255B determines that the movement speed of the helmet 200B is a movement speed at which wearing of the helmet 200B is required (step S301; Yes), the wearing determination unit 256 determines whether the person is properly wearing the helmet 200B (step S302).

[0065] According to the helmet 200B and the wearing determination method according to the third embodiment described above, it is possible to achieve the same effects as the helmet 200A and the wearing determination method according to the second embodiment.

[0066] In the above embodiment, the present invention has been described as a hardware configuration, but the present invention is not limited to this. For example, the present invention can be realized by having a CPU execute a computer program to perform the above-mentioned processing procedures shown in Figures 3, 5, 7, etc.

[0067] The above-mentioned program can be stored using various types of non-transitory computer readable media and can be supplied as a program executed by a computer. The non-transitory computer readable medium includes various types of tangible storage media. Examples of the non-transitory computer readable medium include a magnetic recording medium, an optical recording medium, and a semiconductor memory (e.g., a mask ROM, a programmable ROM (PROM), an erasable PROM (EPROM), a flash ROM, and a RAM). The program may also be supplied to a computer by various types of transitory computer readable media. Examples of the transitory computer readable medium include an electric signal, an optical signal, and an electromagnetic wave. The transitory computer readable medium can supply the program to a computer via a wired communication path such as an electric wire and an optical fiber, or via a wireless communication path.

[0068] The present invention is not limited to the above-mentioned embodiments, and can be modified as appropriate without departing from the spirit of the present invention. For example, the processing of the state determination unit 255 according to the second embodiment may be executed in an information terminal carried by a person wearing the helmet 200A. Similarly, the processing of the state determination unit 255B according to the third embodiment may be executed in an information terminal carried by a person wearing the helmet 200B.
