  "abstract": "To promptly investigate the cause of interruption of Ethernet communication. An anomaly monitoring device includes a power supply, an Ethernet port, an anomaly determination unit configured to determine whether or not an anomaly related to Ethernet communication has occurred between a peripheral device and a control device, an information collection unit configured to collect operation information about operation of the peripheral device when the anomaly determination unit determines that an anomaly related to the Ethernet communication has occurred, and an information transmission unit configured to transmit the collected operation information outside via the Ethernet port, on the basis of the Ethernet communication.",
  "claims": [
    "1. An anomaly monitoring device comprising: a power supply; an Ethernet port; a non-transitory memory configured to store a program; and a hardware processor configured to execute the program and control the anomaly monitoring device to operate as: an anomaly determination unit configured to determine, as an anomaly related to Ethernet communication between a robot peripheral device and a robot control device, at least a state in which a power supply of the robot peripheral device is off, a state in which communication processing in a processer of the robot peripheral device has been hung up, or a state of physical disconnection due to breakage of an Ethernet cable or detachment of the Ethernet cable from an Ethernet port, wherein The robot peripheral device includes the anomaly monitoring device; an information collection unit configured to collect operation information regarding operations of the robot peripheral device, by using the power supply, at a time of the anomaly and when the anomaly determination unit determines that the anomaly related to the Ethernet communication has occurred; and an information transmission unit configured to transmit the collected operation information, by using the power supply, outside of the anomaly monitoring device via the Ethernet port to the robot control device, on the basis of the Ethernet communication.",
    "2. The anomaly monitoring device according to claim 1, wherein the anomaly monitoring device further comprises: a storage configured to store information about the Ethernet communication, wherein the information transmission unit transmits the operation information outside by broadcast communication, on the basis of the information about the Ethernet communication.",
    "3. The anomaly monitoring device according to claim 1, wherein the operation information about the operation of the robot peripheral device indicates a case of the power supply of the robot peripheral device being in an off state, a case of anomalous termination of communication processing, or a case of physical disconnection of an Ethernet cable.",
    "4. The anomaly monitoring device according to claim 1, the anomaly monitoring device being an Ethernet transceiver.",
    "5. The anomaly monitoring device according to claim 1, wherein the robot peripheral device is a teaching operation panel."

  "description_excerpt": "This application is based on and claims the benefit of priority from Japanese Patent Application No. 2019-096594, filed on 23 May 2019, the content of which is incorporated herein by reference.\n\nField of the Invention The present invention relates to an anomaly monitoring device. Related Art A robot system disposed in a factory or the like includes not only a robot control device and a robot body, but also a plurality of robot peripheral devices arranged in the vicinity of the robot, such as a teaching operation panel for teaching a program to the robot control device. It is noted that the robot peripheral device may further include a belt conveyor, a rail-type conveying carriage, or the like. In an example, the robot control device is connected to each of the plurality of robot peripheral devices by an Ethernet cable, via an Ethernet port of the robot control device, so as to exchange information such as an operation command based on a program, by Ethernet (registered trademark) communication. This realizes the advanced operation of a robot in conjunction with the operation of a plurality of robot peripheral devices. In a known art, with respect to such advanced operation of a robot, in the case where the operation state of the robot or robot peripheral devices are monitored, and where the detected operation state deviates from a specified operation range or a specified speed, a robot stop signal or a peripheral device stop signal is output. For examples, Patent Document 1 should be referred to.",
