Description

[Technical Field]

[0001] The present disclosure relates to a mobile terminal capable of communicating with a controller for a hydraulic pump device via wireless communication, a program for the mobile terminal, and a method for processing characteristic data of a hydraulic pump. [Background technology]

[0002] In construction machinery and industrial machinery, a hydraulic pump device that supplies hydraulic oil to a hydraulic actuator may be adopted, and the hydraulic pump device includes at least one pump whose discharge capacity, which is the amount of discharge per rotation, increases as the pump command current increases (see, for example, Patent Document 1). In this case, the hydraulic pump device is controlled by a controller so that the pump's discharge capacity increases as the operating speed of the hydraulic actuator increases.

[0003] Specifically, an actuator operation signal corresponding to the operation amount of an operation device for operating the hydraulic actuator is input to the controller. The operation device determines the operating speed of the hydraulic actuator based on the operation amount of the operation device. A pump command current corresponding to the actuator operation signal is output from the controller to the hydraulic pump device. [Prior art documents] [Patent documents]

[0005] Incidentally, pumps in hydraulic pump units vary in Iq characteristics, which are the relationship between pump command current and discharge capacity, due to individual differences. Patent Document 1 describes a method in which a code storing characteristic data indicating the pump's actual Iq characteristics (Patent Document 1 describes the relationship between command current and discharge flow rate, but the discharge capacity is determined by dividing the discharge flow rate by the rotation speed) is displayed on the surface of the hydraulic pump unit, the characteristic data is input into a controller for the hydraulic pump unit using a code reader, and the controller electronically calibrates the variation in Iq characteristics due to individual differences. Specifically, the controller adjusts the pump command current output to the hydraulic pump unit so as to obtain a set discharge capacity corresponding to the amount of operation of the operating device.

[0006] In response to this, there is a demand for inputting characteristic data into a controller using a portable terminal instead of a code reader.

[0016] 1 shows a calibration system according to one embodiment, including a mobile terminal 4. A program is installed in the mobile terminal 4.

[0017] In addition to the portable terminal 4, the calibration system includes a hydraulic pump unit 1 and a controller 2 for the hydraulic pump unit 1. The portable terminal 4 is capable of communicating with the controller 2 via wireless communication.

[0018] In this embodiment, a wireless LAN router 3 is connected to the controller 2 by wire, and the mobile terminal 4 communicates wirelessly with the wireless LAN router 3. However, the controller 2 may include a wireless communication module, and the mobile terminal 4 may directly communicate wirelessly with the controller 2.

[0019] 2, the hydraulic pump device 1 includes at least one variable displacement pump 11 and at least one regulator 12 that changes the displacement of the corresponding pump 11. In this embodiment, the hydraulic pump device 1 includes two pumps 11 (a first pump 11A and a second pump 11B) and two regulators 12. However, the hydraulic pump device 1 may include only one pump 11.

[0020] In this embodiment, each pump 11 is a swash plate pump (axial piston pump). Furthermore, in this embodiment, the hydraulic pump unit 1 is a tandem type in which the central axes of the two pumps 11 are aligned coaxially. However, the hydraulic pump unit 1 may also be a parallel type in which the central axes of the two pumps 11 are aligned parallel to each other. Alternatively, the hydraulic pump unit 1 may include one or two bent-axis pumps as the pumps 11.

[0021] The hydraulic pump unit 1 is driven by a prime mover (an engine or an electric motor). Whether the hydraulic pump unit 1 is a tandem type or a parallel type, it includes one input shaft, and this input shaft is connected to the output shaft of the prime mover.

[0022] A pump command current I is input to each regulator 12 from the controller 2. The discharge volume q of each pump 11, which is the discharge amount per rotation, increases as the pump command current I input to the corresponding regulator 12 increases.

[0023] For example, the regulator 12 may change the hydraulic pressure acting on a servo piston connected to the swash plate of the pump 11 in accordance with the pump command current I. In this case, the servo piston moves in a direction that increases the tilt angle of the swash plate as the pump command current I increases. Alternatively, the regulator 12 may be an electric actuator connected to the swash plate.

[0024] Each pump 11 supplies hydraulic oil to a hydraulic actuator. The number of hydraulic actuators may be one or more. An actuator operation signal corresponding to the operation amount of an operation device for operating the hydraulic actuator is input to the controller 2. The controller 2 outputs a pump command current I corresponding to the actuator operation signal to a corresponding regulator 12 (the regulator 12 of the pump 11 that supplies hydraulic oil to the hydraulic actuator corresponding to the operated operation device).

[0025] Returning to FIG. 1, two codes 5 (a first code 5A corresponding to the first pump 11A and a second code 5B corresponding to the second pump 11B) are displayed on the surface of the hydraulic pump unit 1. If the hydraulic pump unit 1 includes only one pump 11, only one code 5 is displayed on the surface of the hydraulic pump unit 1. Alternatively, one code 5 may store characteristic data, which will be described later, of two pumps 11.

[0026] Regarding the display of the code 5 on the surface of the hydraulic pump apparatus 1, the code 5 may be printed on a plate, and the plate may be attached to the hydraulic pump apparatus 1. Alternatively, the code 5 may be printed directly on the surface of the hydraulic pump apparatus 1.

[0027] The first code 5A stores characteristic data indicating the actual Iq characteristic of the first pump 11A (the relationship between the pump command current I and the discharge capacity q), and the second code 5B stores characteristic data indicating the actual Iq characteristic of the second pump 11B. For example, the code 5 is a matrix-type two-dimensional code (QR code (registered trademark)). The first code 5A may also store characteristic data indicating the actual IQ characteristic of the first pump 11A (the relationship between the pump command current I and the discharge flow rate Q) and a predetermined pump rotation speed N, and the same applies to the second code 5B.

[0028] The mobile terminal 4 includes a memory 41, a touch screen 42, a camera 43, a wireless communication module 44, and a processor 45. These elements are connected to each other by a bus 46. For example, the mobile terminal 4 is a tablet terminal, a smartphone, or the like.

[0029] The memory 41 includes, for example, a main memory such as a RAM or a ROM, and a storage such as a hard disk or a flash memory. The above-mentioned programs are stored in the memory 41. The touch screen 42 functions as an input device and an output device. The processor 45 is configured by, for example, a CPU.

[0030] The functions of the elements disclosed herein can be performed using circuits or processing circuits, including general-purpose processors, special-purpose processors, integrated circuits, ASICs (Application Specific Integrated Circuits), conventional circuits, and / or combinations thereof, configured or programmed to perform the disclosed functions. A processor is considered a processing circuit or circuit because it includes transistors and other circuitry. In this disclosure, a circuit, unit, or means is hardware that performs the recited functions or hardware that is programmed to perform the recited functions. The hardware may be hardware disclosed herein or other known hardware that is programmed or configured to perform the recited functions. Where the hardware is a processor, which is considered a type of circuit, the circuit, means, or unit is a combination of hardware and software, and the software is used to configure the hardware and / or processor.

[0031] The processor 45 of the mobile terminal 4 performs the following operations in accordance with the program stored in the memory 41.

[0032] When a program icon representing the program displayed on the touch screen 42 is tapped, the processor 45 displays a screen such as that shown in Fig. 3 on the touch screen 42. Specifically, the processor 45 displays a first display frame 61 for displaying information about the first pump 11A and a second display frame 62 for displaying information about the second pump 11B on the touch screen 42. For example, the processor 45 displays "Pump 1" in the first display frame 61 and "Pump 2" in the second display frame 62.

[0033] The processor 45 also displays a pump icon 7 representing the hydraulic pump unit 1 in the first display frame 61 and the second display frame 62. The pump icon 7 includes a first region 71 indicating the position of the first pump 11A and a second region 72 indicating the position of the second pump 11B. As described above, the hydraulic pump unit 1 of this embodiment is a tandem type, and therefore the first region 71 and the second region 72 are aligned in the axial direction of the input shaft. However, if the hydraulic pump unit 1 is a parallel type, the first region 71 and the second region 72 may be aligned in a direction perpendicular to the axial direction of the input shaft, as shown in FIG. 6.

[0034] 3 and 6, the processor 45 displays the pump icon 7 so that the first region 71 is emphasized in the first display frame 61, and displays the pump icon 7 so that the second region 72 is emphasized in the second display frame 62. The method of emphasis may be, for example, to make the first region 71 or the second region 72 a distinctive color.

[0035] Returning to FIG. 3, the processor 45 further displays a virtual code reading start button 63, a characteristic data transmission button 64, and a characteristic data reset button 65 on the touch screen 42.

[0036] The code reading start button 63 is for receiving an input to start reading the first code 5A and the second code 5B displayed on the surface of the hydraulic pump device 1. When the code reading start button 63 is tapped by the user, the processor 45 activates the camera 43.

[0037] When the camera 43 comes into focus on the first code 5A or the second code 5B, it automatically captures the image of the first code 5A or the second code 5B. When the camera 43 captures the image of the first code 5A, the processor 45 acquires the characteristic data of the first pump 11A stored in the first code 5A and stores the acquired characteristic data in the memory 41. Similarly, when the camera 43 captures the image of the second code 5B, the processor 45 acquires the characteristic data of the second pump 11B stored in the second code 5B and stores the acquired characteristic data in the memory 41. Acquiring the characteristic data stored in the code 5 by capturing the image of the code 5 (the first code 5A or the second code 5B) is called reading the code 5.

[0038] Before the first code 5A and the second code 5B are read, the processor 45 displays the first display frame 61 and the second display frame 62, for example, in gray, to indicate that the first code 5A and the second code 5B have not been read.

[0039] When the first code 5A is captured by the camera 43, the processor 45 changes the color of the first display frame 61 to clearly indicate that the first code 5A has been read, as shown in Fig. 4. For example, the first code 5A may also store the serial number of the hydraulic pump device 1, and when the second code 5B is captured by the camera 43, the processor 45 may display the serial number in the first display frame 61.

[0040] Similarly, when the second code 5B is captured by the camera 43, the processor 45 changes the color of the second display frame 62 to clearly indicate that the second code 5B has been read.

[0041] By changing the color of the first display frame 61 or the second display frame 62 in this way, it is possible to show the user of the mobile terminal 4 which of the first code 5A and the second code 5B has been read, and also to let the user know which code needs to be read next.

[0042] Furthermore, when the first code 5A or the second code 5B is captured twice in succession by the camera 43, the processor 45 displays on the touch screen 42 that the second reading was an error. For example, when the first code 5A is captured twice in succession, the processor 45 may display "Reading Error" in the second display frame 62 (or in the first display frame 61), as shown in FIG. 5. This makes it possible to inform the user of the portable terminal 4 that the second reading was an error.

[0043] The virtual characteristic data transmission button 64 described above is for receiving an input to transmit characteristic data to the wireless LAN router 3. When the characteristic data transmission button 64 is tapped after reading of the first code 5A and the second code 5B is completed, the processor 45 causes the wireless communication module 44 to transmit the characteristic data of the first pump 11A and the characteristic data of the second pump 11B stored in the memory 41 to the wireless LAN router 3. As a result, the characteristic data of the first pump 11A and the characteristic data of the second pump 11B are input to the controller 2 via the wireless LAN router 3.

[0044] The controller 2 electronically calibrates the variations in the Iq characteristics of the first pump 11A and the second pump 11B due to individual differences. Specifically, the controller 2 uses the input characteristic data to adjust the pump command current I output to the regulator 12 so as to obtain a set discharge capacity corresponding to the operation amount of the operating device.

[0045] The virtual characteristic data reset button 65 is for accepting an input to reset the characteristic data of the first pump 11A and the characteristic data of the second pump 11B that has been input to the controller 2. When the characteristic data reset button 65 is tapped, the processor 45 causes the wireless communication module 44 to transmit a reset signal to the wireless LAN router 3 to reset the characteristic data. As a result, the reset signal is input to the controller 2 via the wireless LAN router 3.

[0046] When the reset signal is input, the controller 2 determines the pump command current I using an Iq characteristic map pre-stored in the controller 2. This stops the electronic calibration of the variations in Iq characteristics due to individual differences. That is, by tapping the characteristic data reset button 65, the calibration by the controller 2 can be canceled by operating the mobile terminal 4.

[0047] As described above, in this embodiment, the code 5 (first code 5A or second code 5B) displayed on the surface of the hydraulic pump device 1 is read by the camera 43, and the characteristic data of the pump 11 (first pump 11A or second pump 11B) stored in the code 5 is transmitted from the mobile terminal 4 to the wireless LAN router 3 connected to the controller 2. Therefore, the characteristic data of the pump 11 can be input from the mobile terminal 4 to the controller 2.

[0048] In addition, in this embodiment, the first display frame 61 and the second display frame 62 are displayed on the touch screen 42, so that the display screen of the touch screen 42 can be made a display screen suitable for a hydraulic pump device 1 including two pumps 11, namely, the first pump 11A and the second pump 11B.

[0049] (Variation) The present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the gist of the present disclosure.

[0050] For example, if the controller 2 includes a wireless communication module, when the characteristic data transmission button 64 is tapped, the processor 45 of the mobile terminal 4 causes the wireless communication module 44 to transmit the characteristic data of the first pump 11A and the characteristic data of the second pump 11B to the controller 2. In this case, when the characteristic data reset button 65 is tapped, the processor 45 of the mobile terminal 4 causes the wireless communication module 44 to transmit the above-mentioned reset signal to the controller 2. The characteristic data reset button 65 may be omitted.

[0051] In the above embodiment, the first code 5A stores the characteristic data of the first pump 11A, and the second code 5B stores the characteristic data of the second pump 11B. However, the first code 5A may store storage destination information for the characteristic data of the first pump 11A, and the second code 5B may store storage destination information for the characteristic data of the second pump 11B. The storage destination information may be, for example, the Internet Protocol (IP) address of the server where the data is to be stored, or a uniform resource locator (URL) of a specific level on the server. In this case, the first code 5A and the second code 5B may be character strings.

[0052] 7 , when the first code 5A and the second code 5B store information on where to save the characteristic data, the processor 45 of the mobile terminal 4 may, when the first code 5A is captured by the camera 43, obtain the characteristic data of the first pump 11A from the server 9 specified by the storage location information stored in the first code 5A via the network 8 and store the characteristic data in the memory 41. Similarly, when the second code 5B is captured by the camera 43, the processor 45 may obtain the characteristic data of the second pump 11B from the server 9 specified by the storage location information stored in the second code 5B via the network 8 and store the characteristic data in the memory 41.

[0053] With this configuration, the code 5 (first code 5A or second code 5B) displayed on the surface of the hydraulic pump device 1 is read by the camera 43, and characteristic data of the pump 11 (first pump 11A or second pump 11B) is acquired from the server 9 specified by the storage destination information stored in the code 5. The acquired characteristic data is then transmitted from the mobile terminal 4 to the wireless LAN router 3 connected to the controller 2. Therefore, the characteristic data of the pump 11 can be input from the mobile terminal 4 to the controller 2.

[0054] In addition, even if the first code 5A and the second code 5B store information on where to save the characteristic data, the controller 2 may include a wireless communication module, and the processor 45 of the mobile terminal 4 may cause the wireless communication module 44 to transmit the characteristic data of the first pump 11A and the characteristic data of the second pump 11B to the controller 2.

[0055] Furthermore, the processor 45 of the mobile terminal 4 does not necessarily need to display the virtual code reading start button 63 on the touch screen 42, but may instead activate the camera 43 when a program icon displayed on the touch screen 42 is tapped.

[0056] (summary) From a first aspect, the present disclosure provides a mobile terminal including a processor, a memory, a wireless communication module, a touch screen, and a camera, wherein the processor, when at least one code displayed on a surface of a hydraulic pump unit is imaged by the camera, stores in the memory characteristic data of at least one pump included in the hydraulic pump unit, the characteristic data stored in the at least one code, displays on the touch screen a virtual characteristic data transmission button for receiving input for transmitting the characteristic data to a controller for the hydraulic pump unit or a wireless LAN router connected to the controller, and, when the characteristic data transmission button is tapped, causes the wireless communication module to transmit the characteristic data stored in the memory to the controller or the wireless LAN router.

[0057] According to the above configuration, the code displayed on the surface of the hydraulic pump device is read by a camera, and the pump characteristic data stored in the code is transmitted from the mobile terminal to the controller or a wireless LAN router connected to the controller, thereby enabling the pump characteristic data to be input from the mobile terminal to the controller.

[0058] From a second aspect, the present disclosure provides a mobile terminal including a processor, a memory, a wireless communication module, a touch screen, and a camera, wherein the processor, when at least one code displayed on the surface of a hydraulic pump unit is imaged by the camera, acquires characteristic data of at least one pump included in the hydraulic pump unit via a network from a server specified by storage destination information stored in the at least one code, and stores the data in the memory; displays a virtual characteristic data transmission button on the touch screen for receiving input for transmitting the characteristic data to a controller for the hydraulic pump unit or a wireless LAN router connected to the controller; and, when the characteristic data transmission button is tapped, causes the wireless communication module to transmit the characteristic data stored in the memory to the controller or the wireless LAN router.

[0059] According to the above configuration, the code displayed on the surface of the hydraulic pump device is read by a camera, the pump characteristic data is acquired from a server specified by the storage destination information stored in the code, and the acquired characteristic data is transmitted from the mobile terminal to the controller or a wireless LAN router connected to the controller. Thus, the pump characteristic data can be input from the mobile terminal to the controller.

[0060] For example, the processor may display a virtual code reading start button on the touch screen to receive an input to start reading the at least one code, and start the camera when the code reading start button is tapped. Alternatively, the processor may start the camera when a program icon displayed on the touch screen and representing a program installed on the mobile terminal is tapped.

[0061] The at least one pump may include a first pump and a second pump, the at least one code may include first code storing characteristic data of the first pump and second code storing characteristic data of the second pump, the processor may display on the touch screen a first display frame for displaying information about the first pump and a second display frame for displaying information about the second pump, and may display a pump icon representing the hydraulic pump system, including a first region indicating a position of the first pump and a second region indicating a position of the second pump, in the first display frame and the second display frame, the pump icon being displayed in the first display frame so that the first region is emphasized, and the pump icon being displayed in the second display frame so that the second region is emphasized. With this configuration, the display screen of the touch screen can be made suitable for a hydraulic pump system including two pumps, the first pump and the second pump.

[0062] The processor may store characteristic data of the first pump in the memory and change the color of the first display frame when the first code is captured by the camera, and may store characteristic data of the second pump in the memory and change the color of the second display frame when the second code is captured by the camera. This configuration allows the user of the mobile device to know whether the first code or the second code has been read and to know which code needs to be read next.

[0063] When the first code or the second code is captured twice in succession by the camera, the processor may display on the touch screen that the second reading was an error. This configuration makes it possible to inform the user of the mobile terminal that the second reading was an error.

[0064] The processor may display a virtual characteristic data reset button on the touch screen for receiving an input to reset the characteristic data transmitted to the controller or the wireless LAN router, and when the characteristic data reset button is tapped, cause the wireless communication module to transmit a signal to reset the characteristic data to the controller or the wireless LAN router. With this configuration, calibration on the controller can be canceled by operating the mobile terminal.

[0065] From a third aspect, the present disclosure provides a program for a mobile terminal including a processor, a memory, a wireless communication module, a touch screen, and a camera, the program causing the processor to, when at least one code displayed on a surface of a hydraulic pump unit is imaged by the camera, store in the memory characteristic data of at least one pump included in the hydraulic pump unit stored in the at least one code, display on the touch screen a virtual characteristic data transmission button for receiving input for transmitting the characteristic data to a controller for the hydraulic pump unit or a wireless LAN router connected to the controller, and, when the characteristic data transmission button is tapped, cause the wireless communication module to transmit the characteristic data stored in the memory to the controller or the wireless LAN router.

[0066] According to the above configuration, the code displayed on the surface of the hydraulic pump device is read by a camera, and the pump characteristic data stored in the code is transmitted from the mobile terminal to the controller or a wireless LAN router connected to the controller, thereby enabling the pump characteristic data to be input from the mobile terminal to the controller.

[0067] From a fourth aspect, the present disclosure provides a program for a mobile terminal including a processor, a memory, a wireless communication module, a touch screen, and a camera, the program causing the processor to, when at least one code displayed on the surface of a hydraulic pump unit is imaged by the camera, obtain characteristic data of at least one pump included in the hydraulic pump unit via a network from a server specified by storage destination information stored in the at least one code, store the data in the memory, display a virtual characteristic data transmission button on the touch screen for accepting input to transmit the characteristic data to a controller for the hydraulic pump unit or a wireless LAN router connected to the controller, and, when the characteristic data transmission button is tapped, cause the wireless communication module to transmit the characteristic data stored in the memory to the controller or the wireless LAN router.

[0068] According to the above configuration, the code displayed on the surface of the hydraulic pump device is read by a camera, the pump characteristic data is acquired from a server specified by the storage destination information stored in the code, and the acquired characteristic data is transmitted from the mobile terminal to the controller or a wireless LAN router connected to the controller. Thus, the pump characteristic data can be input from the mobile terminal to the controller.

[0069] For example, the program may cause the processor to display a virtual code reading start button on the touch screen to receive an input to start reading the at least one code, and start the camera when the code reading start button is tapped. Alternatively, the program may cause the processor to start the camera when a program icon displayed on the touch screen and representing the program is tapped.

[0070] The at least one pump may include a first pump and a second pump, the at least one code may include first code storing characteristic data of the first pump and second code storing characteristic data of the second pump, and the program may cause the processor to display on the touch screen a first display frame for displaying information about the first pump and a second display frame for displaying information about the second pump, and to display a pump icon representing the hydraulic pump system, including a first region indicating the position of the first pump and a second region indicating the position of the second pump, in the first display frame and the second display frame, and to display the pump icon in the first display frame so that the first region is emphasized, and to display the pump icon in the second display frame so that the second region is emphasized.
