The invention discloses an integrated mobile collaborative robot control system based on a field bus, and relates to the technical field of robot control. The system comprises a task decomposition unit for decomposing tasks corresponding to a robot, a task monitoring unit for obtaining the quantity of remaining tasks of the robot, a comprehensive analysis unit for analyzing the pre-completion degree Dj of the robot, and a task distribution unit for redistributing the remaining tasks according to the pre-completion degree Dj. According to the system, task delay caused by insufficient electric quantity is avoided by pre-estimating the completion condition of each robot for distributed tasks, reasonable scheduling is performed in combination with the conditions of the tasks and the robots, the tasks are re-distributed in time, it is ensured that each task is completed smoothly, and the robot is prevented from being insufficient in power, each task and the corresponding power consumption form a power consumption table, and the power consumption table is updated in real time to form data reference of each task and the corresponding power consumption, so that a reference basis is provided for distribution of subsequent tasks, the tasks are reasonably distributed, and the task completion efficiency is improved.
