[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2009-023574 Summary of the Invention

[0006] Technical problem to be solved by the invention

[0007] A retrofitted object is equipped with multiple retrofit control devices (retrofit electronic control units, or ECUs) to control the retrofitted object. The more retrofit control devices installed in the retrofitted object, the more retrofit information the retrofit control devices must output. Consequently, it takes a long time to obtain the required retrofit information.

[0008] This disclosure focuses on these key points, with the goal of obtaining only the necessary installation information.

[0009] Means used to solve problems

[0010] In a first aspect of the present disclosure, there is provided an installation information acquisition device, comprising: a storage unit, which stores identification information of the installation information, the installation information including control information for controlling the installation body and the above-mentioned identification information for identifying the control information; and an installation information acquisition unit, which acquires the installation information including the identification information stored in the storage unit when the installation information is sent and received between multiple installation control devices installed in the installation body.

[0011] The installation information acquisition section may acquire a copy of the installation information transmitted and received between the plurality of installation control devices.

[0012] Even if the time when the installation information including the identification information stored in the storage unit is sent and received is before the predetermined time has passed after the installation information is acquired, the installation information acquisition unit does not need to acquire the installation information including the identification information stored in the storage unit, and if the installation information including the identification information stored in the storage unit is sent and received between multiple installation control devices after the predetermined time has passed since the installation information was acquired, the installation information acquisition unit can acquire the installation information including the identification information stored in the storage unit.

[0013] The installation information acquisition device may further include an output control unit that outputs the installation information acquired by the installation information acquisition unit to a vehicle body control device that controls a vehicle body connected to the installation body, so that a storage unit of the vehicle body control device stores the installation information acquired by the installation information acquisition unit.

[0014] The installation information acquisition unit can further acquire a sending instruction for outputting the installation information to an external device together with the installation information, and if the installation information acquisition unit acquires the sending instruction, the output control unit can output the installation information acquired by the installation information acquisition unit to the external device through the vehicle body control device.

[0015] The additional information acquisition unit can further acquire a sending instruction for outputting the additional information to an external device, and if the sending instruction is acquired together with the additional information, the output control unit can cause the additional information to be sent to the external device without causing the additional information to be stored in the storage unit of the vehicle body control device, and if only the additional information is acquired, the output control unit can cause the storage unit of the vehicle body control device to store the additional information.

[0016] The storage unit can store acquisition information, which includes identification information included in one or more installation information to be acquired from multiple installation information sent and received between multiple installation control devices, and the installation information acquisition unit can acquire installation information, which includes identification information included in acquisition information from multiple installation information sent and received between multiple installation control devices.

[0017] The installation information acquisition unit may acquire new acquisition information and may update the acquisition information stored in the storage unit to the acquired new acquisition information.

[0028] <Overview of Information Transmission System S>

[0029] Figure 1 This is a diagram for explaining an overview of an information transmission system S according to an embodiment. The information transmission system S includes a vehicle V, a vehicle body server 4, and a retrofitting server 5. The vehicle body server 4 is a server managed by the manufacturer of the vehicle body B of the vehicle V. The retrofitting server 5 is a server managed by the manufacturer of the retrofitting body A. The vehicle V and the vehicle body server 4 are interconnected so as to enable communication. The vehicle body server 4 and the retrofitting server 5 are also interconnected so as to enable communication. The information transmission system S transmits information about the vehicle body B to the vehicle body server 4. Furthermore, the information transmission system S transmits information about the retrofitting body A to the retrofitting server 5 via the vehicle body server 4.

[0030] Vehicle V includes an attachment A and a vehicle body B connected to attachment A. For example, vehicle V is a dump truck, a concrete mixer truck, a tank truck, a refrigerated freezer truck, an aerial work platform, a camper, a fire truck, or an ambulance. Attachment A is equipped with various devices for operating attachment A and sensors for detecting the status of these devices. For example, if attachment A is an aerial work platform, attachment A is equipped with a lift for raising and lowering a work platform on which an operator rides during operation, as well as sensors for detecting the status of the lift (e.g., the oil pressure in the cylinder).

[0031] Furthermore, the installation body A is equipped with an installation control device 2a and an installation control device 2b that control various devices installed in the installation body A. Hereinafter, when it is not necessary to distinguish the installation control device 2a and the installation control device 2b from each other, they are referred to as a plurality of installation control devices 2. Alternatively, in addition to the above, Figure 1 In addition to the case where two retrofit control devices 2 are installed in the retrofit body A, three or more retrofit control devices 2 may also be installed in the retrofit body A.

[0032] The vehicle body B is equipped with a vehicle body control device 3 for controlling the vehicle body B. The vehicle body control device 3 includes a storage unit ( Figure 2 The storage unit 31) and the sending unit ( Figure 2The storage unit 31 stores information for controlling the vehicle body B. The storage unit 31 includes a storage medium such as a read-only memory (ROM), a random access memory (RAM), and a hard disk. The storage unit 31 stores vehicle body information, including control information for controlling the vehicle body B and vehicle body identification information for identifying the control information.

[0033] The transmission unit 32 is a wireless communication module for transmitting at least one of the information regarding the vehicle body B and the information regarding the attachment body A to the vehicle body server 4. For example, the transmission unit 32 may transmit the information to the vehicle body server 4 using a mobile phone network. For example, the mobile phone network may be a fourth-generation mobile communication system or a fifth-generation mobile communication system. The transmission unit 32 may transmit the information to the vehicle body server 4 using Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0034] Multiple installation control devices 2 send and receive installation information to control various devices installed in the installation body A. The more installation control devices 2 are installed in the installation body A, the more installation information is output from the installation control devices 2, so it takes a long time to obtain the required information.

[0035] Accordingly, the vehicle V is equipped with the installation information acquisition device 1 that acquires only necessary information among a plurality of pieces of installation information transmitted and received between a plurality of installation control devices 2. Next, the configuration of the installation information acquisition device 1 will be described.

[0036] <Configuration of Additional Information Acquisition Device 1 According to the Embodiment>

[0037] Figure 2 1 is a diagram for explaining the configuration of the attachment information acquisition device 1 according to the embodiment. The attachment information acquisition device 1 includes a storage unit 11 and a control unit 12. The storage unit 11 includes storage media such as ROM, RAM, and a hard disk. The storage unit 11 stores programs executed by the control unit 12.

[0038] The storage unit 11 stores acquisition information indicating the installation-side identification information to be acquired from one or more pieces of installation information transmitted and received between the plurality of installation control devices 2. For example, the storage unit 11 stores a collection table as the acquisition information, the collection table including the installation-side identification information to be acquired from the one or more pieces of installation information. Figure 3 The collection table R is schematically shown. Figure 3As shown,

[01] ,

[02] , and

[04] are stored as the attachment side identification information included in the attachment information to be acquired. It should be noted that, for example, the attachment side identification information stored in the storage unit 11 is identification information for identifying control information necessary for the management and operation of the attachment A. For example, the control information necessary for the management and operation of the attachment A is the oil pressure, operating time, or fault code of the cylinder.

[0039] In addition, the storage unit 11 can store a conversion rule in which the vehicle body side identification information used in the vehicle body control device 3 is associated with the installation side identification information. Specifically, the storage unit 11 stores a conversion table as a conversion rule in which the vehicle body side identification information is associated with the installation side identification information. The storage unit 11 can store the conversion rule by associating the vehicle body side identification information with each piece of installation side identification information in the collection table R. Figure 3 As shown, the attachment-side identification information and the vehicle-side identification information are associated with each other in a one-to-one correspondence.

[0040] The control unit 12 is a computing resource including a processor such as a central processing unit (CPU). By executing programs stored in the storage unit 11 , the control unit 12 functions as an installation information acquisition unit 121 , an installation information conversion unit 122 , and an output control unit 123 .

[0041] The installation information acquisition unit 121 acquires installation information including control information for controlling the installation object A and installation side identification information for identifying the control information. Figure 4 : is a diagram for explaining the installation information Dr. The installation control device 2 outputs a plurality of installation information Dr (installation information Dr1 and installation information Dr2). Alternatively, the installation control device 2 may output one installation information Dr or three or more installation information Dr.

[0042] The installation information Dr includes installation-side identification information AID and control information CI. Each piece of installation-side identification information AID and control information CI is digital data represented by 0s and 1s. It should be noted that the installation control device 2 outputs multiple pieces of installation information Dr at predetermined time intervals. For example, the predetermined time interval is 30 milliseconds. The installation information acquisition unit 121 sequentially acquires the installation information Dr output by the installation control device 2.

[0043] The installation information acquisition unit 121 can acquire the installation information Dr at intervals longer than the interval at which the installation control device 2 outputs the installation information Dr. For example, the installation information acquisition unit 121 acquires the installation information Dr output from the installation control device 2 100 milliseconds (longer than 30 milliseconds) after acquiring the installation information Dr. Specifically, the installation information acquisition unit 121 discards the installation information Dr output from the installation control device 2 when 100 milliseconds have passed since acquiring the installation information Dr. This allows the installation information acquisition unit 121 to reduce processing load by preventing it from acquiring information other than necessary.

[0044] Control information CI is information used to control the installation body A, such as the oil pressure of the cylinder, the operating status of each device installed in the installation body A, or a fault code used when a fault occurs in each device. The control information CI may include the name of the installation manufacturer, the model or type of the installation body, the product serial number of the installation body, etc. It should be noted that the installation information acquisition unit 121 can acquire the control information CI without knowing the details of the control information CI. In other words, the installation information acquisition unit 121 acquires the control information CI as digital data represented by binary digits 0 and 1, and does not acquire the details of the information indicated by the acquired digital data. Alternatively, the control information CI can be expressed not only in binary digits, but also in hexadecimal digits. For example, for this reason, another user cannot understand what the value of the control information CI means. Therefore, the user who manages the installation server 5 can keep the contents of the control information CI confidential from other users.

[0045] The installation information acquisition unit 121 monitors the communication between the plurality of installation control devices 2 installed in the installation body A. Specifically, the installation information acquisition unit 121 monitors the communication performed between the installation control device 2a and the installation control device 2b so as not to interfere with the communication (see Figure 2 dashed line in the middle).

[0046] When the installation information Dr including the installation-side identification information AID stored in the storage unit 11 is transmitted and received, the installation information acquisition unit 121 acquires the installation information Dr. Specifically, the installation information acquisition unit 121 determines whether the installation information Dr transmitted and received between the installation control device 2a and the installation control device 2b includes the installation-side identification information AID stored in the storage unit 11. More specifically, the installation information acquisition unit 121 determines whether the installation information Dr transmitted and received includes any one of the installation-side identification information AID

[01] ,

[02] , or

[04] included in the collection table R stored in the storage unit 11. Then, if the installation information Dr transmitted and received between the installation control device 2a and the installation control device 2b includes the installation-side identification information AID in the collection table R, the installation information acquisition unit 121 copies the installation information Dr and acquires a copy of the installation information Dr.

[0047] Figure 5 It is a diagram for explaining the process of acquiring the installation information Dr. Figure 5 Part (1) schematically shows a plurality of installation information Dr sent and received between a plurality of installation control devices 2. Figure 5 As shown, it is assumed that the installation information Dr1, the installation information Dr2, and the installation information Dr3 are transmitted and received between a plurality of installation control devices 2. The installation information acquisition unit 121 specifies the installation side identification information AID included in the installation information Dr1, the installation information Dr2, and the installation information Dr3, respectively. Then, the installation information acquisition unit 121 copies each of the installation information Dr1 including the installation side identification information AID

[01] and the installation information Dr2 including the installation side identification information AID

[02] , both of which are included in the collection table R, and the installation information acquisition unit acquires their respective copies. Since the installation side identification information AID

[03] of the installation information Dr3 is not included in the collection table R, the installation information acquisition unit 121 does not acquire the installation information Dr3. Figure 5 Part (2) in FIG. 1 shows a plurality of pieces of installation information Dr (installation information Dr1 and installation information Dr2) acquired by the installation information acquisition section 121 .

[0048] The installation information acquisition unit 121 does not need to acquire the installation information Dr until a predetermined time has passed since the previous instance of acquiring the installation information Dr. For example, after acquiring the installation information Dr, the installation information acquisition unit 121 does not acquire the installation information Dr including the installation-side identification information AID stored in the storage unit 11, even if the installation information Dr is being transmitted and received before the predetermined time has passed since the previous acquisition of the installation information Dr. The predetermined time is longer than the time interval (e.g., 30 milliseconds) at which the plurality of installation control devices 2 transmit and receive the installation information Dr, and the predetermined time is, for example, 100 milliseconds.

[0049] Then, if the installation information Dr including the installation-side identification information AID stored in the storage unit 11 is transmitted and received between the plurality of installation control devices 2 after a predetermined time has passed since the previous acquisition of the installation information Dr, the installation information acquisition unit 121 acquires the installation information Dr including the installation-side identification information AID. Due to this, the installation information acquisition unit 121 can prevent the acquisition of more pieces of installation information Dr than the information necessary for the management and operation of the installation object A.

[0050] The installation information conversion unit 122 converts the installation-side identification information AID included in the installation information Dr into vehicle-side identification information BID associated with the installation-side identification information AID. Specifically, the installation information conversion unit 122 first refers to the acquisition table R stored in the storage unit 11 and specifies the vehicle-side identification information BID associated with the acquired installation-side identification information AID. The installation information conversion unit 122 then converts the acquired installation-side identification information AID into the specified vehicle-side identification information BID. It should be noted that the installation information conversion unit 122 converts the installation-side identification information AID included in the installation information Dr into vehicle-side identification information BID, but does not convert the control information CI.

[0051] Figure 6 1 is a diagram for explaining a process of converting the installation information Dr into the converted installation information Dc. Figure 6 As shown, the installation information conversion unit 122 converts the installation side identification information AID

[01] included in the installation information Dr1 into the vehicle body side identification information BID

[11] by referring to the collection table R, and does not convert the control information CI1[1100101] included in the installation information Dr1.

[0052] The output control unit 123 outputs the attachment information Dr to the vehicle body control device 3. For example, the output control unit 123 outputs the attachment information Dr to the vehicle body control device 3, causing the storage unit 31 of the vehicle body control device 3 to store the attachment information Dr. Furthermore, the output control unit 123 may output converted attachment information Dc, obtained by converting the attachment information Dr using the attachment information conversion unit 122, to the vehicle body control device 3, causing the converted attachment information Dc to be stored in the storage unit 31. This allows the vehicle body control device 3 to store control information CI necessary for managing and operating the attachment A in the storage unit 31.

[0053] Furthermore, the output control unit 123 may cause the installation information Dr to be output to at least one of the vehicle body server 4 and the installation server 5, which are external devices, via the transmission unit 32 of the vehicle body control device 3. In this case, the installation control device 2 outputs a transmission instruction to output the installation information Dr to the external device, and the installation information acquisition unit 121 further acquires the transmission instruction.

[0054] Figure 7: is a diagram for explaining the sending instruction TR. The installation control device 2 outputs the sending instruction TR together with the installation information Dr. For example, the sending instruction TR includes the sending identification information TID for identifying the sending instruction TR and the instruction information SI indicating whether to send the installation information Dr. The sending identification information TID is preset. In this embodiment,

[90] is set as the sending identification information TID. In addition, in this embodiment, if the instruction information SI is

[00] , the instruction information SI indicates that the installation information Dr is not sent, and if the instruction information SI is

[01] , the instruction information SI indicates that the installation information Dr is to be sent.

[0055] The installation information acquisition unit 121 acquires the transmission instruction TR output by the installation control device 2. If the installation information acquisition unit 121 acquires the transmission instruction TR including instruction information

[01] indicating that the installation information Dr is to be transmitted, the installation information acquisition unit 121 notifies the output control unit 123 of an instruction to transmit the installation information Dr1 acquired along with the transmission instruction TR. Then, upon receiving the instruction to transmit the installation information Dr1 from the installation information acquisition unit 121, the output control unit 123 transmits the installation information Dr to the installation server 5 via the transmission unit 32 of the vehicle body control device 3 and the vehicle body server 4. In addition, the output control unit 123 may transmit the converted installation information Dc obtained by converting the installation-side identification information AID into the vehicle-side identification information BID using the installation information conversion unit 122 to the installation server 5.

[0056] In this way, the output control unit 123 can transmit the installation information Dr to the installation server 5 when the installation control device 2 outputs the transmission command TR. Therefore, by causing the installation control device 2 to output the transmission command TR at a predetermined time, the installation information Dr can be transmitted to the installation server 5 at the predetermined time. Therefore, if the installation body A fails or if its parts need to be replaced, the installation information Dr can be immediately transmitted to the installation server 5 without having the vehicle body control device 3 store the installation information Dr.

[0057] <Flow of Processing Executed by Additional Information Acquisition Device 1>

[0058] Figure 8 1 is a flowchart showing an example of the flow of processing performed by the installation information acquisition device 1. The installation information acquisition unit 121 monitors communication between multiple installation control devices 2 (S1). For example, the installation information acquisition unit 121 monitors communication performed between the installation control device 2a and the installation control device 2b so as not to interfere with the communication.

[0059] Next, the installation information acquisition unit 121 determines whether the installation information Dr transmitted and received between the installation control device 2a and the installation control device 2b includes the installation information Dr to be acquired (S2). Specifically, the installation information acquisition unit 121 determines whether the transmitted and received installation information Dr includes the installation-side identification information AID stored in the storage unit 11. More specifically, the installation information acquisition unit 121 specifies the installation-side identification information AID included in the transmitted and received installation information Dr and determines whether the specified installation-side identification information AID is included in the collection table R.

[0060] If the transmitted and received installation information Dr includes the stored installation side identification information AID ("Yes" in S2), the installation information acquisition unit 121 copies the installation information Dr and acquires a copy of the installation information Dr (S3). The installation information acquisition unit 121 waits for a predetermined time (e.g., 100 milliseconds) after acquiring the installation information Dr, and returns to the process of S1 after the predetermined time has passed since the installation information Dr was acquired.

[0061] If the installation information Dr does not include the stored installation-side identification information AID (No in S2 ), the installation information acquisition section 121 returns to the process of S1 without acquiring the installation information Dr. The installation information acquisition device 1 repeats the above-described process when the vehicle V is activated.

[0062] <Example after modification>

[0063] The installation side identification information AID stored in the storage unit 11 may be rewritable. For example, the installation information acquisition device 1 obtains new installation side identification information AID from the installation server 5 through the vehicle body server 4 and the vehicle body control device 3. Specifically, the installation information acquisition device 1 obtains a new list including one or more installation side identification information AIDs. Then, the installation information acquisition device 1 updates the installation side identification information AID in the collection table R stored in the storage unit 11 of the installation information acquisition device 1 to the installation side identification information AID included in the obtained new list. Therefore, the manufacturer of the installation body A can appropriately rewrite the installation side identification information AID so as to change the installation information Dr to be obtained as needed.

[0064] <Effects of Installing the Information Acquisition Device 1 According to the Embodiment>

[0065] As described above, the installation information acquisition device 1 according to this embodiment stores the installation-side identification information AID of the installation information Dr, including the control information CI for controlling the installation object A and the installation-side identification information AID for identifying the control information CI. When the installation information Dr is transmitted and received between multiple installation control devices 2 installed in the installation object A, the installation information acquisition device 1 acquires the installation information Dr including the stored installation-side identification information AID. This allows the installation information acquisition device 1 to acquire only the necessary installation information Dr from the installation information Dr transmitted and received between the multiple installation control devices 2.

[0066] The present disclosure is described on the basis of exemplary embodiments. The technical scope of the present disclosure is not limited to the scope described in the above embodiments, and various changes and modifications are possible within the scope of the present disclosure. For example, all or part of the device may be configured with any functionally or physically dispersed or integrated units. In addition, new exemplary embodiments generated by any combination of them are also included in the exemplary embodiments. In addition, the effects of the new exemplary embodiments brought about by the combination also have the effects of the original exemplary embodiments.
