TECHNICAL FIELD

[0001] The present application relates to an information system and an operation device. BACKGROUND

[0002] According to a remote information system that remotely operates a construction machine, an image signal captured by a camera provided to the construction machine is transmitted via a network and displayed on a monitor device of a remote operation device (control room) provided at a remote place (for example, refer to Patent Document 1).

[0003] PRIOR ART DOCUMENT PATENT DOCUMENT Patent Document 1: Japanese Patent Publication No. 2013-168777

[0004] A system that saves image data displayed on a monitor device of a remote operation device as operation history information of a construction machine and enables reference to the saved image data is desired. It is assumed that the image data is saved to an external server of the remote operation device that enables online access.

[0005] However, if the image data is uploaded to a server, the line will be congested, and thus, when the line is used for a purpose other than the upload of the image data, communication quality in the purpose will be degraded, such as communication delay or slow response. SUMMARY

[0006] An object of the present application is to provide an information system and an operation device that can suppress degradation of communication quality.

[0007] An information system according to the present application, in a case where a specified communication other than transmission of image data acquired by a specified device is performed between the specified device and an external server, the specified device being at least one of an operation device and an operation object operated by the operation device, executes a specified communication control process that either suspends transmission of the image data by the specified device or reduces a speed of the transmission of the image data.

[0008] "Acquisition" of image data is a concept that includes acquisition of the image data using an imaging device and reception of the image data using a communication device. In addition to communication between a second specified device and an external server being controlled in a case where image data acquired once by a first specified device is acquired (or received) twice by the second specified device from the first specified device, communication between the first specified device and the external server can also be controlled in a case where information acquired once by the first specified device is controlled.

[0009] The operating device involved in this invention includes: a display device for displaying image data received from the operating object; and a communication device for sending the image data to an external server, and, in the event of specified communication with the external server other than the sending of the image data, performing specified communication control processing to suspend the sending of the image data or reduce the sending speed of the image data.

[0015] (The structure of an information system) Figure 1 It is an explanatory diagram related to the structure of an information system. Figure 2 This is an explanatory diagram related to the structure of the remote operation device. Figure 3 These are explanatory diagrams related to the structure of engineering machinery. Figure 1 The information system shown in one embodiment of the present invention comprises a remote operating device 20 (operating device), which is configured to communicate with both an external server 10 and the construction machinery 40 (operating object) via network. Alternatively, the information system may include at least one of the external server 10 and the construction machinery 40 (operating object).

[0016] (Structure of the remote operation device) like Figure 1 As shown, the remote operation device 20 includes a remote control device 200 (processing device), a remote input interface 210, and a remote output interface 220. The remote control device 200 is composed of a computing processing device (a single-core processor or a multi-core processor, or a processor core constituting a processor), which reads necessary data and software from storage devices such as memory, and performs computing processing based on the software with the data as the object.

[0017] The remote input interface 210 includes a remote operation mechanism 211. The remote output interface 220 includes a remote image output device 221 (display device) and a remote wireless communication device 222.

[0018] The remote operating mechanism 211 includes a traveling operating device, a slewing operating device, a boom operating device, a stick operating device, and a bucket operating device. Each operating device has an operating lever that accepts rotational operation. The operating lever (traveling lever) of the traveling operating device is operated to move the lower traveling body 41 of the construction machinery 40. The traveling lever may also serve as a traveling pedal. For example, a traveling pedal fixed to the base or lower end of the traveling lever may also be provided. The operating lever (slewing lever) of the slewing operating device is operated to actuate the hydraulic slewing motor constituting the slewing mechanism 43 of the construction machinery 40. The operating lever (boom lever) of the boom operating device is operated to actuate the boom cylinder 442 of the construction machinery 40. The operating lever (stick lever) of the stick operating device is operated to actuate the stick cylinder 444 of the construction machinery 40. The operating lever (bucket stick) of the bucket operating device is operated to actuate the bucket cylinder 446 of the construction machinery 40.

[0019] The levers constituting the remote operating mechanism 211 are, for example, Figure 2 As shown, the seat St is arranged around the operator's seat. Although the seat St is in the form of a high-backed chair with armrests, it can also be in the form of a low-backed chair without a headrest or a chair without a backrest, or any other form of seating where the operator can sit.

[0020] In front of the seat St, left and right travel levers 2110 are arranged side by side, corresponding to the left and right tracks. One lever can also function as multiple levers. For example, Figure 2 The left-side operating lever 2111, located in front of the left side frame of the seat St shown, can function as a boom lever when operated in the forward and backward direction, and as a swivel lever when operated in the left and right direction. Similarly, Figure 2 The right-side operating lever 2112, located in front of the right frame of the seat St shown, can function as a boom lever when operated in the forward and backward direction, and as a bucket lever when operated in the left and right direction. The lever mode can also be changed arbitrarily according to the operator's operating instructions.

[0021] The remote image output device 221 is composed of one or more image output devices. The remote image output device 221 includes: a capture board (output processing device) that outputs the input image information to the screen of the image output device; and a hub (relay device) that inputs image information to the capture board based on the judgment result of the sent image information.

[0022] Remote image output device 221, for example, such as Figure 2 As shown, the system comprises a central remote image output device 2210, a left remote image output device 2211, and a right remote image output device 2212, each with a roughly rectangular screen, positioned in front of, to the left diagonally in front of, and to the right diagonally in front of the seat St. The shape and size of the screens (image display areas) of the central remote image output device 2210, the left remote image output device 2211, and the right remote image output device 2212 may be the same or different. The remote image output device 221 may also consist of a single curved or flexible image output device, or two or more image output devices arranged to surround the front of the seat St.

[0023] like Figure 2 As shown, the right edge of the left remote image output device 2211 is adjacent to the left edge of the central remote image output device 2210 so that the screens of the central remote image output device 2210 and the left remote image output device 2211 are tilted at an angle θ1 (e.g., 120°≤θ1≤150°). Figure 2 As shown, the screens of the central remote image output device 2210 and the right remote image output device 2212 are tilted at an angle θ2 (e.g., 120°≤θ2≤150°), with the left edge of the right remote image output device 2212 adjacent to the right edge of the central remote image output device 2210. The tilt angles θ1 and θ2 may be the same or different.

[0024] The screens of the central remote image output device 2210, the left remote image output device 2211, and the right remote image output device 2212 can be parallel to the vertical direction or tilted relative to the vertical direction. At least one of the image output devices 2210, 2211, and 2212 can also be composed of multiple image output devices. For example, the central remote image output device 2210 can also be composed of vertically adjacent image output devices with a generally rectangular screen.

[0025] (Structure of construction machinery) like Figure 1 As shown, the construction machinery 40 includes a machine control device 400, a machine input interface 410, a machine output interface 420, and a machine wireless communication device 422. Each component of the machine control device 400 is composed of a processing unit (a single-core processor or a multi-core processor, or a processor core constituting a processor), which reads necessary data and software from storage devices such as memory, and performs software-based computational processing based on that data.

[0026] Construction machinery 40, such as tracked excavators (construction machinery), such as Figure 3 As shown, the device includes a tracked lower traveling body 41 and an upper rotating body 42 that is rotatably mounted on the lower traveling body 41 via a rotating mechanism 43. A driver's cab 42C is provided on the front left side of the upper rotating body 42. A working mechanism 44 is provided on the front center of the upper rotating body 42.

[0027] The machine input interface 410 includes a machine operating mechanism 411, a machine camera device 412, a machine positioning device 414, and a machine sensor group 416. The machine operating mechanism 411 has multiple joysticks arranged similarly to the remote operating mechanism 211 around the seat located inside the cockpit 42C. A drive mechanism or robot that receives signals corresponding to the operating states of the remote joysticks and actuates the joysticks based on these received signals is located in the cockpit 42C. The machine camera device 412 is located, for example, inside the cockpit 42C, and captures images of at least a portion of the environment, including the operating mechanism 44, through the front window and left and right side windows. Some or all of the front and side windows may be omitted. The machine positioning device 414 consists of GPS (Global Positioning System) or GNSS (Global Navigation Satellite System), and, if necessary, gyroscope sensors, etc., and measures the position (latitude and longitude) of the construction machinery 40.

[0028] The actual machine sensor group 416 outputs the following signals to the actual machine control device 400, which correspond to the values ​​of parameters related to the state of the construction machinery 40, such as the undulation angle of the boom 441 relative to the upper rotating body 42, the rotation angle of the stick 443 relative to the boom 441, the rotation angle of the bucket 445 relative to the stick 443, the working hydraulic pressure, and the remaining fuel.

[0029] like Figure 3 As shown, the working mechanism 44 includes a boom 441 that is flexibly mounted on the upper rotating body 42, a stick 443 that is rotatably connected to the distal end of the boom 441, and a bucket 445 (distal attachment) that is rotatably connected to the distal end of the stick 443. The working mechanism 44 is equipped with a boom cylinder 442, a stick cylinder 444, and a bucket cylinder 446, all of which are telescopic hydraulic cylinders.

[0030] The boom working cylinder 442 is located between the boom 441 and the upper slewing body 42, and extends and retracts by receiving a supply of working oil, causing the boom 441 to rotate in the undulating direction. The stick working cylinder 444 is located between the stick 443 and the boom 441, and extends and retracts by receiving a supply of working oil, causing the stick 443 to rotate relative to the boom 441 about a horizontal axis. The bucket working cylinder 446 is located between the bucket 445 and the stick 443, and extends and retracts by receiving a supply of working oil, causing the bucket 445 to rotate relative to the stick 443 about a horizontal axis.

[0031] (Function) Figure 4 It is an explanatory diagram related to the functions of an information system. Figure 5 This is an explanatory diagram related to images of the work environment. (Use) Figure 4 The flowchart shown illustrates the functions of the construction assistance device and camera control system of the aforementioned structure. In this flowchart, the "C (number)" block is used for simplified description; it refers to the sending and / or receiving of data, and specifically to the conditional branch that executes the branch direction processing based on the sending and / or receiving of such data.

[0032] In the remote operation device 20, the remote control device 200 sends a specified signal to the construction machinery 40 via the remote wireless communication device 222. Figure 4 (Step 210). When multiple construction machines 40 are multiple candidate operation objects, a designated signal can be sent to each of the multiple construction machines 40. It can also be determined whether a designated operation has been performed by the operator through the remote input interface 210, and if the determination result is positive, a designated signal is sent. A "designated operation" is, for example, a click or other operation in the remote input interface 210 used to specify the construction machine 40 that the operator wants to remotely operate.

[0033] When the construction machinery 40 receives the specified signal through the actual machine wireless communication device 422 ( Figure 4 The machine control device 400 sends the video image (camera image, with appropriate image processing also possible) obtained by the machine camera device 412 as "first machine information" to the remote operation device 20. Figure 4 (Step 410). The camera image (or camera image data) can be the camera image itself, or it can be image data representing a simulated environment generated based on the camera image.

[0034] When the remote operating device 20 receives the first real-time information via the remote wireless communication device 222 ( Figure 4 (C21), the remote control device 200 outputs the camera image as the first real-time information to the remote image output device 221 (display device). Figure 4Step 211). Thus, the camera image is output to the remote image output device 221, the camera image being, for example, Figure 5 As shown, in addition to the ground extending in front of the cab 42C, the boom 441 and stick 443, which are part of the working mechanism 44, as well as piles of rubble or sand in the work area (which are the work objects of the bucket 445) are also captured.

[0035] The remote control device 200 determines whether the second communication condition is sufficient. Figure 4 Step 212). The "second communication condition" includes, for example, the following conditions: specified information that needs to be sent to the external server 10 is stored in the storage device (a designated area of ​​the memory) of the remote operating device 20; the amount of information in the specified information is greater than or equal to the second specified value; a response in the specified manner is received from the external server 10; and / or the operator of the remote operating device 20 performs the operation in the second specified manner through the remote input interface 210. In addition to the "second machine information" described later, the "specified information" may also include information indicating that at least one of the operations of "remote operation start", "remote operation interruption" and "remote operation end" for the construction machinery 40 has been performed through the remote input interface 210.

[0036] Under the condition that the second communication condition is sufficient ( Figure 4 If step 212 is "Yes", the remote control device 200, acting as the "designated device", will send or upload the designated information to the external server 10 via the remote wireless communication device 222. Figure 4 (Step 214). At this time, the physical machine identifier used to identify the construction machinery 40 and the remote identifier used to identify the remote operating device 20 can also be sent or uploaded to the external server 10 in association with the camera image. The external server 10 as the destination for sending "specified information" and the external server 10 as the destination for sending "camera image" can be the same or different. The "specified information" and the "camera image" can each be sent not only from one remote operating device 20 to the external server 10, but also from multiple remote operating devices 20 respectively.

[0037] When external server 10 receives the specified information ( Figure 4 (C11), the specified information is saved or stored in cloud-based information storage resources or databases. Figure 4 Step 110).

[0038] Furthermore, the remote control device 200 performs the "designated communication control processing" ( Figure 4Step 215). Specifically, the uploading of camera images from the remote control device 200 (designated device) to the external server 10 is suspended, or the priority of the camera images to be sent to the external server 10 is relatively lower than the priority of the designated information, for example, by reducing the bandwidth usage of the camera images. During the period when the remote control device 200 determines that the second communication condition is sufficient, the unsent camera images are accumulated or stored in the storage device of the remote control device 200. If the designated communication ends during the execution of the designated communication control process, the transmission of camera image data is restarted, or the communication speed is restored.

[0039] In the case where the second communication condition is deemed insufficient ( Figure 4 If step 212 is "No", the remote control device 200 determines whether the first communication condition is sufficient. Figure 4 Step 216). The "first communication condition" includes, for example, the following conditions: a specified period has elapsed since the last start or end time of uploading a camera image to the external server 10 in the storage device (a specified area of ​​the memory) of the remote operating device 20; and / or the upload of specified information to the external server 10 has been completed in the execution of specified communication processing control. The "first communication condition" may also include conditions such as: a camera image that needs to be sent to the external server 10 is saved or accumulated; the amount of information in the camera image is greater than or equal to a first specified value; and / or the operator of the remote operating device 20 has performed the first specified operation through the remote input interface 210.

[0040] If the first communication condition is deemed sufficient ( Figure 4 If step 216 is "Yes", the remote control device 200, acting as the "designated device", will send or upload the designated information to the external server 10 via the remote wireless communication device 222. Figure 4 Step 218). At this time, the physical machine identifier used to identify the construction machinery 40 and the remote identifier used to identify the remote operating device 20 can also be sent or uploaded to the external server 10 in association with the camera image. When the external server 10 receives the camera image (first physical machine information) ( Figure 4 The C12 image is stored or saved in cloud-based information storage resources or databases. Figure 4 Step 120).

[0041] In the remote operation device 20, the remote control device 200 identifies the operating status of the remote operation mechanism 211 and sends a remote operation command corresponding to the operating status to the construction machinery 40 through the remote wireless communication device 222. Figure 4 Step 220).

[0042] In the construction machinery 40, when the actual machine control device 400 receives a remote operation command through the actual machine wireless communication device 422 ( Figure 4 (C42), according to the remote operation command, controls the actions of the working mechanism 44, etc. Figure 4 Step 420). For example, the following operation is performed: the bucket 445 digs and excavates the soil in the construction target area in front of the construction machinery 40, and after the upper rotating body 42 is rotated, the soil is dumped from the bucket 445 to outside the construction target area.

[0043] Furthermore, the actual machine control device 400 obtains the status of the construction machinery 40 (which may also include the second actual machine information) based on the output signal of the actual machine sensor group 416, and sends the status of the construction machinery 40 to the remote operation device 20. Figure 4 Step 422). The "Second Machine Information" may also include the current position of the construction machinery 40, the tilt angle of the upper slewing body 42, the undulation angle of the boom 441 relative to the upper slewing body 42, the rotation angle of the stick 443 relative to the boom 441, the rotation angle of the bucket 445 relative to the stick 443, the working hydraulic pressure, and the remaining fuel level, among other parameters related to the state of the construction machinery 40. The "Second Machine Information" may also include the operating state of the remote operating mechanism 211 (the amount of operation or tilt angle of the operating lever constituting the remote operating mechanism 211, etc.) or the remote operating command corresponding to the operating state, and / or the motion state of the operating lever constituting the machine operating mechanism 411, etc., controlled according to the remote operating command.

[0044] When the remote operating device 20 receives the second real-time information via the remote wireless communication device 222 ( Figure 4 (C22) The remote control device 200 shall at least temporarily save or store the second real-machine information in a storage device (or, a designated area of ​​the memory, etc.). Further, the remote control device 200 shall repeatedly perform the sufficiency determination process for the second communication condition, followed by further processing (refer to...). Figure 4 Steps 212 to 218).

[0045] (Technical effect) According to the information system that performs the aforementioned function, when there is designated communication between the remote operating device 20 and the external server 10 (communication other than sending camera image data from the remote operating device 20 to the external server 10), the transmission of the camera image is suspended, or the transmission speed is reduced (see reference). Figure 4 Step 212 is "Yes" → Step 214 → Step 215. Therefore, the communication capacity is not excessively limited due to the simultaneous transmission of camera image data and designated communication, and the degradation of the communication quality of the transmission of camera image data and the designated communication can be suppressed.

[0046] When the specified communication ends during the execution of the specified communication control process, resume the transmission of the suspended image data, or restore the reduced transmission rate (see [reference]). Figure 4 (Step 218). Thus, in addition to suppressing the degradation of communication quality of the specified communication, the camera image data will also be successfully sent from the remote operating device 20 to the external server 10, thereby suppressing the degradation of communication quality.

[0047] Upon completion of the specified communication, the camera image data stored in the storage device of the remote operating device 20 will be sent to the external server 10 (see reference). Figure 4 (Step 218). Thus, in addition to suppressing the degradation of communication quality of the specified communication, the camera image data will also be successfully sent from the remote operating device 20 to the external server 10, thereby suppressing the degradation of communication quality.

[0048] (Other embodiments of the present invention) In the described embodiment, the information system is constituted by the remote operating device 20. However, as another embodiment, the information system may be constituted by the construction machinery 40, or by a computer (external server 10, etc.) separate from the remote operating device 20 and the construction machinery 40. The construction machinery 40 (the object of operation) may also be operated by an operator riding on the construction machinery 40 through the physical operating mechanism 411.

[0049] In the described embodiment, the “operation object” is engineering machinery 40 (or construction machinery). However, in other embodiments, the “operation object” may also be any equipment such as drones, vehicles, cranes, or other types of construction machinery that can be remotely operated and have the function of acquiring and sending internal and / or external information.

[0050] In the described embodiment, machine information is uploaded from the remote operating device 20, which is designated as the "designated device," to the external server 10. However, in another embodiment, machine information may also be directly uploaded from the construction machinery 40, which is designated as the "designated device," to the external server 10 (see [reference]). Figure 4 Steps 410 to C11 and from steps 422 to C12). In this case, the information system may also consist of the machine control device 400 of the engineering machinery 40, and the machine control device 400 performs the sufficiency determination process of the second communication condition (see...). Figure 4 Step 212), the process of sending specified information to external server 10 (refer to...) Figure 4 Step 214), specify communication control processing (refer to...) Figure 4 Step 215), the sufficiency determination process of the first communication condition (refer to...)Figure 4 Step 216), and the processing of sending camera images to external server 10 (see step 216). Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Figure 4 Step 218).

[0051] Alternatively, the structure could be as follows: the construction machinery 40 has an automatic driving function, and the remote operation device 20 sends instructions to start, pause, and end the automatic driving of the construction machinery 40. The construction machinery 40 then starts, pauses, and ends the automatic driving according to the instructions.

[0052] The information system according to the first aspect of the present invention performs a specified communication control process to suspend the transmission of the image data performed by the specified device or reduce the transmission speed of the image data when there is specified communication between a specified device and an external server other than the transmission of image data obtained by the specified device. The specified device is at least one of an operating device and an operating object operated by the operating device.

[0053] According to this information system architecture, when there is designated communication (other than sending image data from the designated device to the external server) between the operating device and at least one of the operating objects operated by the operating device, i.e., the designated device, the image data transmission is suspended or the transmission speed is reduced. This avoids excessive limitation of the information communication capacity between the designated device and the external server due to simultaneous image data transmission and designated communication, and further suppresses the degradation of the communication quality of both image data transmission and designated communication.

[0054] "Acquiring" image data includes the concept of acquiring the image data using a camera device and receiving the image data using a communication device. In addition to the control of communication between the second designated device and the external server for image data acquired once by the first designated device and acquired (or received) a second time from the first designated device, the communication between the second designated device and the external server for information acquired once by the first designated device can also be controlled.

[0055] The information system according to the second aspect of the present invention is preferably the information system according to the first aspect, wherein the object of operation is engineering machinery, and the operating device is a remote operating device for remotely operating the engineering machinery.

[0056] According to this information system architecture, when there is designated communication (other than communication other than sending image data obtained by the construction machinery from the operating device to the external server) between the remote operating device used for remote operation of construction machinery, the transmission of image data is suspended or the transmission speed is reduced. This avoids excessive limitation of communication capacity due to simultaneous transmission of image data and designated communication, and further suppresses the degradation of communication quality in both image data transmission and designated communication.

[0057] In the information system according to the third aspect of the present invention, preferably in the information system according to the first or second aspect, the designated device obtains a camera image obtained by the imaging device of the object being operated as the image data.

[0058] According to this information system architecture, when there is designated communication between a designated device and an external server (communication other than sending image data obtained by the operating object through a camera device from the designated device to the external server), the transmission of the image data is suspended or the transmission speed is reduced. This avoids excessive limitation of the communication capacity used for the designated communication due to image data transmission, and consequently, suppresses the degradation of the communication quality of the designated communication.

[0059] The information system according to the fourth aspect of the present invention is preferably an information system according to the first to third aspects, wherein the designated communication is a communication used to manage at least one of the operation start, operation interruption and operation end of the operation device on the operation object.

[0060] According to this information system architecture, when there is designated communication between the operating device and an external server (communication other than sending image data obtained by the camera device of the work object from the operating device to the external server), the transmission of the image data is suspended or the transmission speed is reduced. This avoids excessive limitation of the communication capacity used for designated communication due to image data transmission, and further suppresses the degradation of the communication quality of the designated communication (communication used to manage at least one of the start, interruption, and end of operation of the operating device regarding the work object).

[0061] In the information system according to the fifth aspect of the present invention, preferably in the information systems according to the first to fourth aspects, if the designated communication ends during the execution of the designated communication control process, the transmission of the image data by the designated device is restarted, or the communication speed is restored.

[0062] According to this information system architecture, when a specified communication ends during the execution of the specified communication control process, the previously suspended transmission of image data from the specified device to the external server is restarted, or the reduced transmission speed is restored. Thus, in addition to suppressing the degradation of communication quality in the specified communication, image data is also successfully transmitted from the specified device to the external server, thereby suppressing the degradation of communication quality.

[0063] The information system according to the sixth aspect of the present invention is preferably an information system according to the first to fifth aspects, wherein the designated device accumulates the image data during the execution of the designated communication control process, and after the designated communication ends, the designated device sends the accumulated image data.

[0064] According to this information system architecture, upon the termination of a specified communication, the image data stored on the specified device is sent from that device to an external server. This not only suppresses the degradation of communication quality during the specified communication but also ensures that the image data is successfully sent from the specified device to the external server, thereby mitigating the degradation in communication quality.

[0065] The operating apparatus according to the seventh aspect of the present invention includes: a display device for displaying image data received from the operating object; and a communication device for sending the image data to an external server, and performing specified communication control processing to suspend the sending of the image data or reduce the sending speed of the image data when there is specified communication with the external server other than the sending of the image data.

[0066] According to the operating device of this structure, when there is designated communication (other than the communication from the operating device to the external server) between the operating device and the external server, the transmission of the image data is suspended or the transmission speed is reduced. This avoids excessive limitation of the communication capacity used for the designated communication due to the transmission of image data, and consequently, the degradation of the communication quality of the designated communication can be suppressed.
