Abstract

A communication system of an industrial machine includes an in-vehicle network, an information communication network, and a communication device of an information collecting unit. The in-vehicle network N 1 performs data communication in a plurality of electronic devices 7 mounted on the industrial machine (backhoe 1 ). The information communication network is an external network of the backhoe and is a network different from the in-vehicle network. The communication device connects the in-vehicle network to the information communication network. The communication device 30 C transmits the in-vehicle data D when data communication is performed by the plurality of electronic devices 7 in the in-vehicle network N 1 to the information communication network N. As a result, the in-vehicle data configured via the in-vehicle network in the backhoe can be transmitted without any change to the information communication network outside the backhoe.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2022-208350 filed on Dec. 26, 2022 in Japan, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present invention relates to, for example, an industrial machine such as an agricultural machine or a construction machine, and a communication system of the industrial machine. RELATED ART Conventionally, as a system for diagnosing a failure of a work machine, there is a failure diagnosis support system in JP 2011-74639 A (Claim 1, paragraph 0022, and the like). In the failure diagnosis support system in JP 2011-74639 A (Claim 1, paragraph 0022, and the like), an operation status of each part of the work machine is converted into an image. The image is read and transmitted as an operation status to an external terminal via a network. In a case where the terminal receives the operation status, a failure is automatically estimated on the basis of the operation status and a repair record. In the system in JP 2011-74639 A (Claim 1, paragraph 0022, and the like), operation information of the work machine is converted into an image of a QR code (registered trademark) at a timing at which diagnosis is requested. An operation status is transmitted to an external terminal by reading the image. On the other hand, in a case where only the operation information at the timing at which diagnosis is required is used, an amount of information for diagnosis may be reduced, and it is difficult to easily and accurately execute diagnosis. As information to be transmitted to the terminal, for example, a continuous temporal change at a level at which a change tendency can be appropriately analyzed is preferable in many cases. JP 2011-74639 A (Claim 1, paragraph 0022, and the like) does not disclose a technique related to this viewpoint. As described above, there is a demand for a technique for easily and accurately executing diagnosis of a part of an industrial machine at a place remote from the industrial machine. Therefore, in view of the above problems, an object of the present invention is to provide an industrial machine and a communication system of the industrial machine capable of easily and accurately performing diagnosis of a part of the industrial machine at a place remote from the industrial machine. SUMMARY The technical means of the present invention for solving this technical problem is characterized by the following points.
