Description

TECHNICAL FIELD

[0001] The utility model relates to electrical control field especially relates to a robot control cabinet automatic power-off restart detection system. BACKGROUND

[0002] In the field of modern industrial automation, robot control cabinets play a crucial role. It integrates the core components of robots, including controllers, drivers, and IO boards, etc. These components are connected through high-speed EtherCAT networks, ensuring that robots can accurately and efficiently perform tasks. However, after the robot control cabinet is powered on, sometimes the communication network connection between the controller, driver and IO board fails. This situation may be caused by internal problems of the control cabinet, such as hardware failure, software configuration error or unstable network connection, etc.

[0003] In order to ensure the reliability and stability of the robot control cabinet when used by end customers, pre-shipment detection becomes particularly important. The traditional detection method requires manual power-off and restart, which not only consumes time and effort, but also is inefficient, making it difficult to meet the needs of large-scale production. Therefore, developing an automated and efficient detection process is of great significance to improve production efficiency and reduce costs.

[0004] In the EtherCAT network, due to the inconsistency of network cable quality and device performance, it may cause unstable or failed network connection. This requires that before the control cabinet is shipped, it must be tested multiple times for power-off and restart to ensure that all components can work stably under various conditions. Such a testing process is crucial to ensure the performance of robots in actual application, because any communication failure may cause the robot to stop working, affecting the normal operation of the production line.
