Abstract: The present invention relates to an industrial robot process cloud system and a working method thereof. The industrial robot process cloud system comprises an industrial robot control system integrated with a human machine interaction layer HMI, a motion planning control layer Motion and a servo loop control layer Servo, and further comprises a cloud server, wherein the cloud server comprises a process expert system. The human machine interaction layer HMI and the motion planning control layer Motion realize data interaction with the cloud server by means of a network, after the human machine interaction layer HMI inputs operation information, the operation information is transmitted to the cloud server, and a specific robot operation program is generated and downloaded into the industrial robot control system by means of the network.
