[0011] First Embodiment 1 is a block diagram showing an example of the configuration of a tank truck operation management device 10. The tank truck operation management device 10 includes a content information acquisition unit 110, a license identification unit 120, a holder determination unit 130, a certificate determination unit 140, and an operation switching unit 150.

[0012] The content information acquisition unit 110 acquires information about the contents of the tank of the tank truck. The tank truck transports a tank filled with a solid, liquid, or gas, such as chemicals or petroleum. The tank truck may carry the tank or may tow the tank. The information about the contents includes, for example, the type of the contents and the amount or weight of the contents, but is not limited to these.

[0013] The content information acquisition unit 110 may acquire, as information on the contents, for example, the type of the contents injected and the weight or volume of the contents measured at the time of injection from a device that injects the contents into the tank. The content information acquisition unit 110 may acquire information on the contents from a sensor installed at the entrance of the tank or inside the tank. The content information acquisition unit 110 may acquire information on the contents from a device that measures the tank truck. For example, the content information acquisition unit 110 may acquire, as the weight of the contents, the difference in the weight of the tank truck before and after the injection of the contents from a weighing scale that measures the weight of the tank truck. The content information acquisition unit 110 may acquire the weight of the contents calculated from the difference in tire air pressure before and after the injection of the contents from a sensor that measures the tire air pressure. Note that some cargo vehicles such as tank trucks have a number of tires that are on the ground that changes depending on the weight of the cargo. When the tank truck is such a vehicle, the content information acquisition unit 110 may acquire the weight of the contents estimated from the number of tires that are on the ground from a management unit that manages the tires used in the vehicle. The content information acquiring unit 110 may acquire content information from other devices, without being limited to the above.

[0014] The qualification identifying unit 120 identifies the qualification required for the transfer of the content based on the information of the content. For example, the qualification identifying unit 120 may identify the following qualifications: ·Hazardous materials: Hazardous materials handler qualification. Poisonous substances: Notification of business handling by a business establishment that has a person in charge of handling poisonous and hazardous substances. ·High Pressure Gas: Completion of high pressure gas transportation supervisor training course. Explosives: A transportation certificate issued by the Prefectural Public Safety Commission. The license specification unit 120 may specify a license other than the above. For example, when a tank truck tows a tank, the driver needs a towing license in addition to a large vehicle license. Therefore, the license specification unit 120 may specify the license (such as a large vehicle license and a towing license) required to drive the target tank truck.

[0015] The license holder determination unit 130 determines whether or not a license holder is on board the tank truck. For example, the license holder determination unit 130 may obtain a face image of a passenger in the driver's seat from a camera provided in the driver's seat, and may determine whether or not a license holder is on board based on face authentication using the obtained face image. The license holder determination unit 130 may use other biometric authentication such as iris or fingerprint, not limited to face authentication. However, for example, when the license is a dangerous materials handler, the license holder may be the driver or may be a passenger other than the driver. Therefore, for example, when the license is a dangerous materials handler, the license holder determination unit 130 may determine whether or not at least one license holder of a dangerous materials handler is included among the passengers. Furthermore, the license holder determination unit 130 may determine multiple licenses. For example, the license holder determination unit 130 may determine whether or not a license holder of a dangerous materials handler is included among the passengers, and further determine whether or not the driver in the driver's seat is a large vehicle license holder.

[0016] The certificate determination unit 140 determines whether or not a certificate indicating a qualification held by the holder is loaded on the tank truck. For example, when the certificate is placed in a predetermined location of the driver's seat, the certificate determination unit 140 may analyze an image of the driver's seat to determine whether or not the certificate is loaded on the tank truck. When the certificate has an IC (Integrated Circuit) tag for radio frequency identification (RFID), the certificate determination unit 140 may obtain information on the qualification from the IC tag of the certificate. The IC tag may also be called an RFID tag.

[0017] The certificate judgment unit 140 may judge the holder of the certificate. For example, if the certificate includes a face image, the certificate judgment unit 140 may judge the holder of the certificate based on face authentication using the face image of the certificate. Alternatively, the certificate judgment unit 140 may judge the certificate issue number from the image of the certificate and judge the holder of the certificate from the issue number. If the certificate is an IC tag, the certificate judgment unit 140 may acquire information on the holder of the certificate from the IC tag. In these cases, the holder judgment unit 130 or the certificate judgment unit 140 may judge whether the holder of the certificate judged by the certificate judgment unit 140 matches the holder of the qualification to board the tank truck judged by the holder judgment unit 130. If they do not match, the holder judgment unit 130 or the certificate judgment unit 140 may output an alert to a system of the management department of the tank truck.

[0018] The certificate may be of any form or name as long as it is a certificate that certifies the qualifications required for the transfer of the contents. For example, the certificate may be a license, permit, qualification, certification, registration, exemption, certificate of completion, or notification.

[0019] When the manager stores the confirmation results of the holder and the certificate confirmed by using a list or the like in the management system, the holder determination unit 130 and the certificate determination unit 140 may determine the consistency between the stored confirmation results of the manager and the respective determination results. For example, the manager uses a tablet or the like to register the confirmation results that the holder of the necessary qualification is on board and that the certificate of the qualification is on board in the management system of the tank truck. Then, the holder determination unit 130 determines whether the holder of the qualification is on board the tank truck, and determines whether the determined qualified person matches the qualified person registered by the manager. Then, when the qualified person registered by the manager does not match the qualified person determined, the holder determination unit 130 outputs an alert to the system of the management department of the tank truck or the mobile terminal of the manager. Alternatively, the certificate determination unit 140 determines whether the certificate indicating the qualification held by the holder of the qualification is on board the tank truck, and determines whether the determined certificate matches the certificate registered by the manager. If the certificate registered by the administrator and the determined certificate do not match, the certificate determination unit 140 outputs an alert to the system of the tanker truck management department or to the administrator's mobile terminal.

[0020] The operation switching unit 150 switches the tank truck between operable and inoperable based on the result of the determination of whether the holder of the license is on board the tank truck and the result of the determination of whether the certificate is loaded on the tank truck. For example, the operation switching unit 150 may output operation switching information indicating either operable or inoperable to an operation control unit that controls the engine of the tank truck. For example, when the passengers include a holder of the license and the certificate is loaded on a predetermined location of the tank truck, the operation switching unit 150 may output operation switching information that enables the engine or motor of the tank truck to be started. In addition to starting the engine, the operation switching unit 150 may output operation switching information that enables the shift lever to be moved from the parking position, for example. Alternatively, the operation switching unit 150 may output operation switching information that enables the handbrake to be released. Alternatively, the operation switching unit 150 may output operation switching information that enables the accelerator pedal to function. When the holder of the qualification is not on board the tanker truck and / or when the certificate is not loaded on the tanker truck, the operation switching unit 150 outputs operation switching information that disables the tanker truck from operating.

[0021] The qualification specification unit 120 may specify whether or not the state of the contents of the tank indicates that a qualification is no longer required. For example, when the contents are discharged from the tank, a qualification is no longer required to operate the tank truck. Thus, for example, the tank truck operation management device 10 may operate as follows. The contents information acquisition unit 110 acquires information indicating that the contents have been discharged from a device that discharges the contents into the tank. Then, the qualification specification unit 120 specifies that the state of the contents of the tank indicates that a qualification is no longer required based on the information indicating that the contents have been discharged. Then, when the state of the contents of the tank is specified as a state in which a qualification is no longer required, the operation switching unit 150 outputs operation switching information that enables the tank truck to operate.

[0022] The qualification specification unit 120 may use other information to specify whether or not a qualification is required. For example, in many cases, no qualification is required to operate a tanker truck within a factory. Therefore, for example, the qualification specification unit 120 may use location information to determine whether the person is inside or outside the factory, specify that no qualification is required within the factory, and specify the qualification that is required when leaving the factory. For example, in the case where an IC tag is provided at the entrance / exit of the factory, the qualification specification unit 120 may acquire location information by referring to the information on the IC tag. Alternatively, the qualification specification unit 120 may acquire location information by using a global positioning system (GPS).

[0023] The operation switching unit 150 may use information on the personal items necessary for the transport of the contents. For example, the operation switching unit 150 may output operation switching information that enables the tank truck to operate when a license holder is on board, a certificate is loaded, and personal items are loaded. The personal items include, but are not limited to, protective equipment, fire extinguishers, and tools. For example, when transporting hazardous materials, it is necessary to carry a yellow card (emergency contact card) that clearly states the measures and contact information that transportation personnel, fire department, police, etc. should take in the event of an accident during the transport of chemical substances. The yellow card is a measure and contact document that describes the properties of the chemical substances, first aid methods, emergency contacts, etc., in order to quickly respond to accidents during the transport and transport of chemical substances such as hazardous materials. Therefore, the operation switching unit 150 may output operation switching information for the tank truck based on whether or not the yellow card is loaded. The source of the information on the personal items is not particularly specified. The operation switching unit 150 may obtain, for example, information on an IC tag attached to a portable item from the certificate determination unit 140 or a configuration not shown.

[0024] The operation switching unit 150 may output an alert. For example, when the driver tries to operate the tank truck when the license holder is not on board the tank truck or when the certificate is not loaded on the tank truck, the operation switching unit 150 may output an alert to the system of the management department of the tank truck. The operation switching unit 150 may respond to the certificate being left behind. For example, when it is determined that the license holder is not on board the tank truck and the certificate is loaded on the tank truck, the operation switching unit 150 may output an alert indicating that the certificate has been left behind. For example, the operation switching unit 150 may output an alert indicating that the certificate has been left behind to the system of the management department or a mobile terminal of the license holder.

[0025] FIG. 2 is a flow diagram showing an example of the operation of the tank truck operation management device 10. The content information acquisition unit 110 acquires information on the contents of the tank of the tank truck (step S201). The license identification unit 120 identifies the license required for the transfer of the contents based on the information on the contents (step S202). The holder determination unit 130 determines whether the holder of the license is on board the tank truck (step S203). The certificate determination unit 140 determines whether the certificate indicating the license held by the holder is loaded on the tank truck (step S204). The operation switching unit 150 switches the tank truck between operable and inoperable based on the determination result of whether the holder of the license is on board the tank truck or not and the determination result of whether the certificate is loaded on the tank truck or not. In detail, the operation switching unit 150 first determines whether the holder of the license is on board the tank truck and whether the certificate is loaded on the tank truck or not (step S205). If the license holder is on board the tank truck and the certificate is loaded on the tank truck (Yes in step S205), the operation switching unit 150 enables the tank truck to operate (step S206). If the license holder is not on board the tank truck and / or the certificate is not loaded on the tank truck (No in step S205), the operation switching unit 150 disables the tank truck from operating (step S207).

[0026] In this manner, the tank truck operation management device 10 includes a content information acquisition unit 110, a license identification unit 120, a holder determination unit 130, a certificate determination unit 140, and an operation switching unit 150. The content information acquisition unit 110 acquires information on the contents of the tank of the tank truck. The license identification unit 120 identifies the license required for the transfer of the contents based on the information on the contents. The holder determination unit 130 determines whether the holder of the license is on board the tank truck. The certificate determination unit 140 determines whether the certificate indicating the license held by the holder is loaded on the tank truck. The operation switching unit 150 switches between the operation possible and the operation impossible of the tank truck based on the determination result of whether the holder of the license is on board the tank truck or not, and the determination result of whether the certificate is loaded on the tank truck or not. For example, the operation switching unit 150 enables the tank truck to operate when the holder of the license is on board the tank truck and the certificate is loaded on the tank truck. On the other hand, the operation switching unit 150 disables the tank truck when the license holder is not on board the tank truck and / or when the certificate is not loaded on the tank truck. In this way, the tank truck operation management device 10 manages switching between operable and inoperable states of the tank truck in accordance with the license required to transport the contents of the tank of the tank truck. Therefore, the tank truck operation management device 10 reduces the manager's burden of managing the operation of the tank truck related to the license.

[0027] <Second embodiment> When transporting dangerous goods by tank truck, it is necessary to post signs indicating the dangerous goods in easily visible locations on the front and rear of the tank truck. Figure 3 is a diagram showing an example of a tank truck sign. For the management of tank truck operations, it is preferable to manage the signs in addition to the qualifications. Therefore, a tank truck operation management device 11 that operates including the signs will be described.

[0028] FIG. 4 is a block diagram showing an example of the configuration of the tank truck operation management device 11 that operates including the sign. The tank truck operation management device 11 includes a sign information acquisition unit 160 in addition to the configuration of the tank truck operation management device 10. The content information acquisition unit 110, the license identification unit 120, the holder determination unit 130, and the certificate determination unit 140 operate in the same manner as in the first embodiment. The sign information acquisition unit 160 acquires information on the sign mounted on the tank truck. For example, when the sign includes an IC tag, the sign information acquisition unit 160 may acquire the sign information from the IC tag. Then, the operation switching unit 150 enables the tank truck to operate when the license holder and the certificate, as well as the sign information, correspond to the contents. The tank truck operation management device 11 configured in this manner can enable the tank truck to operate when a sign corresponding to the contents is mounted. The sign information acquisition unit 160 may acquire other information, not limited to the sign information. For example, the sign information acquisition unit 160 may acquire information on personal belongings necessary for transporting the contents instead of the certificate determination unit 140 or a configuration not shown. In this way, the tank truck operation management device 11 manages switching between operable and inoperable states of the tank truck based on the license holder, the license certificate, and the license label determination result. Therefore, the tank truck operation management device 11 reduces the manager's burden of managing the operation of the tank truck, including the labels.

[0029] (Modification) The tank truck may be equipped with a display device for a sign. For example, the tank truck may be equipped with a display device at the position of the sign in FIG. 3. In this case, it is preferable to manage the display device so as to correspond to the contents of the tank as the management of the operation of the tank truck. Therefore, a case where the display device is included in the management will be described. FIG. 5 is a block diagram showing an example of the configuration of the tank truck operation management device 12 corresponding to the case where the tank truck is equipped with a display device for a sign. The tank truck operation management device 12 includes a sign information output unit 170 in addition to the configuration of the tank truck operation management device 10. The contents information acquisition unit 110, the qualification identification unit 120, the holder determination unit 130, the certificate determination unit 140, and the operation switching unit 150 operate in the same manner as in the first embodiment. The sign information output unit 170 acquires information on the contents from the contents information acquisition unit 110, and outputs information on the sign corresponding to the contents to the display device mounted on the tank truck. For example, when the contents are dangerous goods, the sign information output unit 170 outputs information for displaying the character "Danger" in yellow on a black background to the display device. The display device displays the sign information. The tanker truck operation management device 12 configured in this manner can display signs corresponding to the contents. Therefore, the tanker truck operation management device 12 reduces the burden on the manager of setting and checking the signs.

[0030] <Hardware configuration> Next, the hardware configuration of the tank truck traffic management devices 10 to 12 will be described. Each component of the tank truck traffic management devices 10 to 12 may be configured with a hardware circuit. Alternatively, each component of the tank truck traffic management devices 10 to 12 may be configured using a plurality of devices connected via a network such as an in-vehicle network. Alternatively, each component of the tank truck traffic management devices 10 to 12 may be configured with a single piece of hardware. Alternatively, the tank truck traffic management devices 10 to 12 may be realized as a computer device including a processor (CPU: Central Processing Unit), a memory, and a network interface (NI: Network Interface). The memory is configured with, for example, a read only memory (ROM: Read Only Memory), a random access memory (RAM: Random Access Memory), and a storage device.

[0031] 6 is a block diagram showing the configuration of a computer device 600 which is an example of the hardware configuration of the tank truck operation management devices 10 to 12. The computer device 600 includes a CPU 610, a ROM 620, a RAM 630, a storage device 640, and an NI 650.

[0032] The CPU 610 reads a program from at least one of the ROM 620 and the storage device 640. The CPU 610 then controls the RAM 630, the storage device 640, and the NI 650 based on the read program. The computer device 600 then controls these components to realize functions as the content information acquisition unit 110, the license identification unit 120, the holder determination unit 130, the certificate determination unit 140, the operation switching unit 150, the sign information acquisition unit 160, and the sign information output unit 170. In this way, the computer device 600 realizes functions as a combination of hardware and software.

[0033] The CPU 610 may read a program contained in a recording medium 690 that stores the program in a computer-readable manner, using a recording medium reading device (not shown). Alternatively, the CPU 610 may receive a program from an external device (not shown) via the NI 650, store the program in the RAM 630 or the storage device 640, and operate based on the stored program.

[0034] The ROM 620 stores programs and fixed data executed by the CPU 610. The ROM 620 is, for example, a programmable ROM (P-ROM) or a flash ROM. The RAM 630 temporarily stores programs and data executed by the CPU 610. The RAM 630 is, for example, a dynamic RAM (D-RAM). The storage device 640 stores data and programs that the computer device 600 stores long-term. The storage device 640 may operate as a temporary storage device for the CPU 610. The storage device 640 is, for example, a hard disk device or a solid state drive (SSD).

[0035] ROM 620 and storage device 640 are non-volatile (non-transitory) recording media. On the other hand, RAM 630 is a volatile (transitory) recording media. CPU 610 can operate based on programs stored in ROM 620, storage device 640, and RAM 630. In other words, CPU 610 can operate using either a non-volatile recording medium or a volatile recording medium. When realizing each function, CPU 610 may use at least one of RAM 630 and storage device 640 as a temporary storage medium for programs and data.

[0036] The NI650 communicates with external devices, such as a smart card reader, a camera, or a system in the administrative department, and transmits data to and from the system via a network. The NI650 is, for example, a wireless local area network (LAN) card.

[0037] The computer device 600 configured in this manner executes the operations of the configurations in the tank truck operation management devices 10 to 12 and realizes the functions of the tank truck operation management devices 10 to 12.

[0038] Although the present invention has been described above with reference to the embodiment, the present invention is not limited to the above embodiment. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
