Information processing apparatus, information processing method, and information processing program

[0001] The present disclosure relates to an information processing apparatus, an information processing method, and an information processing program.

[0002] Japanese Patent No. 5276778 discloses a tire information management system used at a mining site, comprising: sensors attached to each of a plurality of vehicles that transport mineral resources, the sensors measuring tire conditions; and a tire information management device that wirelessly receives measurement values output by the sensors, the tire information management system comprising: a position specifying unit that transmits the current position and destination of the vehicle to the tire information management device; wherein when the received measurement value is not within an allowable range, the tire information management device selects, from a plurality of travel routes for the vehicle that transmitted the measurement value to travel from the current position to the destination, the travel route that is unlikely to impose a large load on the tire, and transmits the selected travel route included in deterioration suppression information for suppressing the progress of tire deterioration to the vehicle that transmitted the measurement value.

[0003] If a tire is damaged when a vehicle is traveling, for example by stepping on an obstacle such as a stone, this will greatly impede the traveling of the vehicle. In particular, the road surface on which mining vehicles for transporting mineral resources travel has many obstacles such as stones, so air leakage from tires is prone to occur. Therefore, if the position where air leakage occurs can be grasped in advance, it becomes possible to prevent tire air leakage.

[0004] An object of the present disclosure is to provide an information processing apparatus, an information processing method, and an information processing program that enable grasping the position where air leakage from a tire occurs.

[0007] The information processing device according to the third embodiment is an information processing device according to the second embodiment in which, when the corrected internal pressure gradually decreases over a predetermined period from the reference point in time when the corrected internal pressure falls below the reference internal pressure, the determination unit determines that the reference point is the time when the air leak occurred, and the output unit outputs the position of the vehicle at the time of occurrence as the air leak occurrence position.

[0008] In the information processing device according to the fourth embodiment, if there is a time before the reference time when the amount of change per unit time of the corrected internal pressure becomes greater than or equal to the normal amount of change, the determination unit determines the time when the air leak occurred, using the reference time as the reference time.

[0014] The information processing device according to the tenth embodiment is an information processing device according to the eighth or ninth embodiment, wherein the output unit outputs a path that avoids the location where the fault occurred.

[0015] The information processing device according to the 11th embodiment is an information processing device according to any one of the first to tenth embodiments, wherein the vehicle is a mining vehicle for transporting mining resources.

[0016] The information processing method according to the 12th embodiment includes the following processes: the computer acquires the internal pressure of the tires of a moving vehicle and the position of the vehicle; determines whether there is an air leak in the tires based on the amount of change in the acquired internal pressure of the tires per unit time; and outputs the position of the vehicle where the air leak occurred as the air leak location.

[0017] The information processing program according to the 13th embodiment causes a computer to perform a process that includes acquiring the internal pressure of the tires of a moving vehicle and the position of the vehicle, determining whether there is an air leak in the tires based on the amount of change in the acquired internal pressure of the tires per unit time, and outputting the position of the vehicle where the air leak occurred as the air leak location.

[0018] This disclosure has the effect of making it possible to determine the location where air leaks occur in tires.

This block diagram shows the hardware configuration of the information processing device according to this embodiment. This block diagram shows the functional configuration of the information processing device according to this embodiment. This flowchart shows an example of the flow of information processing performed by the information processing device according to this embodiment.

[0020] Hereinafter, an example of an embodiment of the technology of this disclosure will be described with reference to the drawings. In each drawing, identical or equivalent components and parts are given the same reference numerals. Also, the dimensional ratios in the drawings may be exaggerated for illustrative purposes and may differ from the actual ratios.

[0021] The information processing device 10 according to this embodiment acquires the internal pressure of the tires and the position of a vehicle transporting mining resources while it is in motion, determines whether there is an air leak in the tires based on the amount of change in the acquired internal pressure per unit time, and outputs the position of the vehicle where the air leak occurred as the air leak location. In the following description, the vehicle transporting mining resources may be referred to as a mining vehicle.

[0022] First, the overall configuration of the information processing device 10 and peripheral devices will be described. Figure 1 is a diagram showing the overall configuration including the information processing device 10 and the mining vehicle 50 according to this embodiment.

[0023] As shown in Figure 1, the information processing system 1 of this embodiment is composed of an information processing device 10 and a plurality of mining vehicles 50. Each mining vehicle 50 is equipped with a communication device 25, various sensors for acquiring tire information, and various sensors for detecting vehicle information representing various driving conditions of the mining vehicle 50.

[0024] The various sensors include multiple TPMS (Tire Pressure Monitoring System) 20 for detecting tire information, a GPS sensor 26 for detecting the position (latitude, longitude, altitude) of the mining vehicle 50 as an example of vehicle information, and a G sensor 27 for detecting the acceleration applied to the mining vehicle 50 as an example of vehicle information (see also Figure 2). The information processing device 10 according to this embodiment is wirelessly connected to the communication device 25 of each mining vehicle 50. The communication device 25 of the mining vehicle 50 is also wirelessly connected to various sensors mounted on the mining vehicle 50. In this way, the information processing device 10 receives tire information and vehicle information of the mining vehicle 50 from multiple mining vehicles 50 that are in motion.

[0025] Figure 2 is a block diagram showing the hardware configuration of the information processing device 10 according to this embodiment. As shown in Figure 2, the information processing device 10 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, storage 14, an input / output I / F (Interface) 15, and a communication I / F 16. Each component is connected to the others via a bus 17 so as to be able to communicate with each other.

[0026] The CPU 11 is a central processing unit that executes various programs and controls various components. Specifically, the CPU 11 reads programs from the ROM 12 and executes them using the RAM 13 as a working area. The CPU 11 controls the above-mentioned components and performs various calculations according to the programs stored in the ROM 12. The CPU 11 is also responsible for processing each of the functional units shown in Figure 3.

[0027] The storage device, comprised of ROM 12, stores various programs, including the operating system, and various data. ROM 12 also stores information processing programs for executing the information processing described later.

[0028] The memory, comprised of RAM 13, temporarily stores programs and data as a working area.

[0029] The storage device 14 is composed of an HDD (Hard Disk Drive) and an SSD (Solid State Drive), and stores various types of data. The storage device 14 also functions as the data storage unit 105 shown in Figure 3, and stores various types of information such as tire information and vehicle information. The storage device 14 does not necessarily have to be built into the information processing device 10; for example, it may be a portable storage device that can be attached to or detached from the information processing device 10, or an external cloud server may be used as the storage device.

[0030] The input / output interface 15 is an interface for communicating with input and output devices located outside the information processing device 10. The input devices include pointing devices such as a mouse and a keyboard, and are used for various types of input. The output devices include, for example, a liquid crystal display or an organic EL (Electroluminescence) display, and are devices for outputting various types of information. The output devices may also function as input devices by employing a touch panel system. The output devices may also be equipped with speakers or other means for audio output. For example, if the information processing device 10 is installed in a mining vehicle 50, the output devices are used as monitors inside the vehicle. Also, if the information processing device 10 is installed in an operation control room, the output devices are used as monitors inside the operation control room.

[0031] The communication interface 16 is an interface for communicating with other devices outside the information processing device 10. For this communication, a wired communication standard such as Ethernet (registered trademark) or FDDI, or a wireless communication standard such as 4G, 5G, or Wi-Fi (registered trademark) can be used. For example, if the information processing device 10 is installed in the operation control room, the information processing device 10 communicates data with each mining vehicle 50 through a wireless line, which is an example of a communication line connected to the communication interface 16. Alternatively, if the information processing device 10 is installed in a mining vehicle 50, the information processing device 10 may communicate data with a server (not shown) installed in the operation control room through a wireless line connected to the communication interface 16, and display tire information for each tire and vehicle information on a monitor installed in the operation control room.

[0032] Furthermore, the communication interface 16 communicates wirelessly with the communication device 25 of the mining vehicle 50. The communication device 25 is installed on the mining vehicle 50 and communicates with the TPMS 20 on each tire of the mining vehicle 50. The communication device 25 installed on each mining vehicle 50 includes a GPS (Global Positioning System) sensor 26 and a G sensor 27, etc. The GPS sensor 26 acquires position information of the mining vehicle 50, and the G sensor 27 detects acceleration in the vertical, horizontal, and longitudinal directions applied to the mining vehicle 50, and transmits each of these from the communication device 25 to the communication interface 16 of the information processing device 10. In addition, the TPMS 20 installed on each tire of the mining vehicle 50 includes at least a temperature sensor 21, a pressure sensor 22, and a transmitter 23.

[0033] The temperature sensor 21 is a sensor that detects the temperature of the tire. The pressure sensor 22 is a sensor that detects the internal pressure of the tire. The transmitter 23 communicates with the communication device 25 of the mining vehicle 50. Specifically, the transmitter 23 transmits the tire temperature detected by the temperature sensor 21 and the internal pressure detected by the pressure sensor 22 to the information processing device 10. The measurements by the temperature sensor 21 and the pressure sensor 22 are performed continuously or at a preset sampling interval. The communication device 25 may also acquire vehicle information such as vehicle speed and yaw rate in addition to acceleration from various sensors mounted on the mining vehicle 50 and transmit it to the information processing device 10.

[0034] Referring to Figure 3, the functional configuration of the information processing device 10 according to this embodiment will be described. As shown in Figure 3, the information processing device 10 of this embodiment includes an acquisition unit 101, a determination unit 102, and an output unit 103. A data storage unit 105 is also provided in a predetermined storage area of ​​the storage 14. The CPU 11 executes a processing program stored in the ROM 12, thereby enabling the acquisition unit 101, determination unit 102, and output unit 103 to function. Various information acquired by the acquisition unit 101 is stored in the data storage unit 105.

[0035] The acquisition unit 101 acquires the internal pressure of the tires of the mining vehicle 50 while it is in motion, as well as the position of the mining vehicle 50. Specifically, the acquisition unit 101 acquires the internal pressure of the tires detected by the pressure sensor 22 and the position of the mining vehicle 50 detected by the GPS sensor 26 by receiving them from the communication device 25.

[0036] The determination unit 102 determines whether there is an air leak in the tire based on the change in the internal pressure of the tire per unit time obtained by the acquisition unit 101. Since air leaks are thought to occur when the tire is damaged by obstacles such as stones, determining whether an air leak has occurred makes it possible to determine whether or not the tire is damaged.

[0037] The output unit 103 outputs the location of the mining vehicle 50 where the determination unit 102 has determined that an air leak has occurred as the air leak location. Specifically, the output unit 103 outputs the air leak location to a monitor in the operation control room for display, or outputs the air leak location to the mining vehicle 50 for display on the monitor of the mining vehicle 50. This allows the operator in the operation control room or the driver of the mining vehicle 50 to know the location of the air leak. This makes it easier to avoid driving in the area of ​​the air leak, to drive at a reduced speed, or to perform road surface maintenance in the area of ​​the air leak.

[0038] Incidentally, since tires generate heat during driving, the internal pressure of the tire will be different from the value when the tire returns to room temperature. For this reason, it is preferable to correct the internal pressure to that of room temperature as needed. In other words, since the measured internal pressure of the tire is affected by temperature, it is preferable to use a value corrected to the internal pressure at a constant temperature as the internal pressure of the tire.

[0039] Therefore, the acquisition unit 101 acquires the tire temperature of the mining vehicle 50 while it is in motion from the temperature sensor 21. Then, the determination unit 102 corrects the acquired tire internal pressure to the internal pressure at room temperature based on the tire temperature and internal pressure acquired by the acquisition unit 101, and determines whether there is an air leak in the tire based on the corrected internal pressure. Methods for correcting (converting) the acquired tire internal pressure to the internal pressure at room temperature include, but are not limited to, methods using Boyle's Law and Charles's Law and methods using a correction formula derived using the results of experiments conducted in advance.

[0040] Furthermore, when a tire leaks air, there are two patterns in which the internal pressure of the tire decreases: a rapid decrease and a gradual decrease. When the internal pressure of the tire decreases rapidly, it is highly likely that the timing of the decrease will be noticed immediately. On the other hand, when the internal pressure decreases gradually, it may not be noticed at the start of the decrease and may only be detected after a certain amount of time has passed. This information processing device is useful in both patterns, but given this background, the benefits are greater when the internal pressure decreases gradually.

[0041] Therefore, the determination unit 102 may determine that the reference point is the time when an air leak occurred if the corrected internal pressure gradually decreases over a predetermined period from the reference point when the corrected internal pressure falls below the standard internal pressure. Specifically, if the decrease in tire internal pressure continues for a predetermined period from the reference point when the corrected internal pressure falls below the standard internal pressure, the determination unit 102 determines that the tire internal pressure is gradually decreasing due to an air leak, and determines that the reference point is the time when the air leak occurred. In this case, the output unit 103 outputs the position of the vehicle at the time the air leak occurred, as determined by the determination unit 102, as the air leak occurrence position.

[0042] Furthermore, if there is a point in time before the reference point when the amount of change in the corrected internal pressure per unit time exceeds the normal amount of change, the determination unit 102 may use that point in time as the reference point to determine the time when the air leak occurred. Here, the normal amount of change is, for example, the amount of change in the corrected internal pressure when the mining vehicle 50 is driving normally with no obstacles on the road surface. Since the point in time when the amount of change in the corrected internal pressure exceeds the normal amount of change is highly likely to be the time when the air leak occurred, this point is used as the reference point. This makes it possible to determine the time when the air leak occurred with high accuracy. Alternatively, the mining vehicle 50 may be equipped with a sensor to detect suspension pressure, and the acquisition unit 101 may acquire the suspension pressure. In this case, if there is a point in time before the reference point when the amount of change in the suspension pressure per unit time exceeds the normal amount of change, the determination unit 102 may use that point in time as the reference point to determine the time when the air leak occurred.

[0043] However, there may be some variation and error in the corrected internal pressure. In this case, even if it is determined that the corrected internal pressure is below the standard internal pressure, it may not actually be below the standard internal pressure. Therefore, the determination unit 102 may determine the time of air leakage by using the lower limit of the error range of the corrected internal pressure as the standard internal pressure. The error range should be calculated in advance through experiments or other means. This can suppress misdetermination of the time of air leakage in the tire.

[0044] Furthermore, the output unit 103 may be configured to output the occurrence frequency of air leakage at the air leakage occurrence position determined by the determination unit 102. This allows the occurrence position of air leakage to be displayed in a display mode corresponding to the occurrence frequency of air leakage on a monitor in an operation control room or a monitor of the mining vehicle 50. Here, the display mode corresponding to the occurrence frequency of air leakage refers to a display mode in which at least one of colors, characters, and marks is changed according to the occurrence frequency, but is not limited thereto.

[0045] Furthermore, the output unit 103 may be configured to output a route that avoids the air leakage occurrence position determined by the determination unit 102. Specifically, for example, a route that avoids the air leakage occurrence position is output to the mining vehicle 50 and displayed on the monitor of the mining vehicle 50. This allows the driver of the mining vehicle 50 to easily travel along a route that avoids the air leakage occurrence position.

[0046] Furthermore, when the acceleration of the mining vehicle 50 in at least one of the vertical direction, left-right direction, and front-rear direction changes significantly compared to when the vehicle is traveling on a road surface without obstacles, it is considered that an impact such as running over an obstacle such as a stone may have been applied, and a failure such as spilling of mining resources from the loading bed may have occurred.

[0047] Accordingly, the acquisition unit 101 acquires, from the G sensor 27, acceleration of the mining vehicle 50 in at least one of the vertical direction, left-right direction, and front-rear direction, the determination unit 102 determines that a position where the amount of change per unit time in the acceleration in at least one of the vertical direction, left-right direction, and front-rear direction acquired by the acquisition unit 101 is equal to or greater than a predetermined threshold is a failure occurrence position where a failure has occurred, and the output unit 103 may output the failure occurrence position determined by the determination unit 102. Here, the predetermined amount of change is set to a value that enables determination of whether an impact has been applied to the mining vehicle 50 by an obstacle such as a stone. This makes it possible to grasp positions where an impact applied to the mining vehicle 50 may cause cargo to spill from the mining vehicle 50 or damage to a tire. Accordingly, it becomes easy to travel while avoiding failure occurrence positions, travel with speed limits, perform road surface maintenance at failure occurrence positions, and the like.

[0048] The output unit 103 may also be configured to output the occurrence frequency of a fault at a fault occurrence position. This enables the fault occurrence position to be displayed in a display mode corresponding to the fault occurrence frequency on a monitor in an operation management room or a monitor of the mining vehicle 50. Here, the display mode corresponding to the fault occurrence frequency refers to, similarly to the display mode corresponding to the occurrence frequency of air leakage, a display mode in which at least one of colors, characters, and marks is changed according to the occurrence frequency, but is not limited thereto.

[0049] In addition, the output unit 103 may be configured to output a route that avoids the fault occurrence position determined by the determination unit 102. Specifically, for example, a route that avoids the fault occurrence position is output to the mining vehicle 50 and displayed on the monitor of the mining vehicle 50. This enables the driver of the mining vehicle 50 to easily travel along a route that avoids the fault occurrence position.

[0050] In addition, the mining vehicle 50 may be provided with a camera that captures images of the surroundings of the mining vehicle 50, and the acquisition unit 101 may acquire captured images captured by the camera while the mining vehicle 50 is traveling. In this case, the output unit 103 may output a captured image captured at an air leakage occurrence position, or may output a captured image captured at a fault occurrence position.

[0051] In addition, the mining vehicle 50 may be provided with a load detection sensor that detects the load of the loading platform, and the acquisition unit 101 may acquire the load detected by the load detection sensor while the mining vehicle 50 is traveling. In this case, the determination unit 102 may determine, as a cargo spill position where cargo has spilled, a position at which a difference between the load when the cargo is loaded and the load during traveling is equal to or greater than a predetermined threshold, and the output unit 103 may output the cargo spill position determined by the determination unit 102.

[0052] Next, specific processing performed by the information processing apparatus 10 according to the present embodiment configured as described above will be described. FIG. 4 is a flowchart showing an example of the flow of information processing performed by the information processing apparatus 10 according to the present embodiment. Note that the processing in FIG. 4 may be started, for example, every predetermined time, or may be started according to a user's instruction.

[0053] In step S100, the CPU 11 acquires tire information and vehicle information and stores it in the storage 14. Specifically, it acquires the temperature of each tire of each mining vehicle 50 detected by the temperature sensor 21 of each mining vehicle 50, the internal pressure of each tire of each mining vehicle 50 detected by the pressure sensor 22 of each mining vehicle 50, the position of each mining vehicle 50 detected by the GPS sensor of each mining vehicle 50, and the acceleration of each mining vehicle 50 in at least one direction of the vertical, horizontal, and longitudinal directions detected by the G sensor 27 of each mining vehicle 50.

[0054] In step S101, the CPU 11 corrects the internal pressure of each tire of each mining vehicle 50 to the internal pressure of the tire at room temperature, based on the tire temperature and internal pressure obtained in step S100.

[0055] In step S102, the CPU 11 determines whether there is an air leak in each tire of each mining vehicle 50 based on the corrected internal pressure corrected in step S101. Specifically, if the corrected internal pressure gradually decreases over a predetermined period from the reference point when the corrected internal pressure falls below the standard internal pressure, the CPU determines that the reference point is the point in time when the air leak occurred.

[0056] In step S103, the CPU 11 determines whether or not there is a mining vehicle 50 that has experienced a tire leak, as determined in step S102. If there is a mining vehicle 50 that has experienced a tire leak, the process proceeds to step S104; otherwise, the process proceeds to step S106.

[0057] In step S104, the CPU 11 stores the location and date / time of the air leak determined in step S102 in the storage 14, and calculates the frequency of occurrence of the air leak determined in step S102.

[0058] In step S105, the CPU 11 outputs the location of the air leak determined in step S102 and the frequency of the leak calculated in step S104 to, for example, a monitor in the operation control room or a monitor on the mining vehicle 50.

[0059] In step S106, the CPU 11 determines whether a malfunction has occurred for each mining vehicle 50 by determining whether the amount of change per unit time of acceleration in at least one direction of the mining vehicle 50 (vertical, horizontal, and longitudinal) obtained in step S100 is greater than or equal to a predetermined threshold.

[0060] In step S107, the CPU 11 determines whether or not there is a mining vehicle 50 that has malfunctioned, as determined in step S106. If there is a mining vehicle 50 that has malfunctioned, the process proceeds to step S108; otherwise, the routine terminates.

[0061] In step S108, the CPU 11 stores the fault location and date / time determined in step S106 in the storage 14, and calculates the frequency of occurrence of the fault location determined in step S106.

[0062] In step S109, the CPU 11 outputs the fault location determined in step S106 and the fault frequency calculated in step S108 to, for example, a monitor in the operation control room or a monitor on the mining vehicle 50.

[0063] As described above, the information processing device 10 according to this embodiment acquires the internal pressure of the tires and the position of the mining vehicle 50 while it is in motion, determines whether there is an air leak in the tires based on the amount of change in the internal pressure of the tires per unit time, and outputs the position of the mining vehicle 50 where the air leak occurred as the air leak location. Therefore, the location where the air leak in the tires occurs can be determined.

[0064] In the above embodiment, the tires of the mining vehicle 50 were described as an example, but the invention is not limited to the tires of the mining vehicle 50, and tires of other vehicles such as passenger cars, trucks, and buses may also be used.

Various modifications or improvements can be made to the embodiments without departing from the spirit, and such modified or improved forms are also included within the technical scope of this disclosure.

[0066] Furthermore, in the above embodiment, the processing performed by the information processing device 10 may be implemented by a software configuration, or each process may be implemented by a hardware configuration. Alternatively, it may be implemented by combining a software configuration and a hardware configuration.
