The invention discloses a smart press-mounting system based on high-end manufacturing and process monitoring. The system includes a displacement sensor, a force sensor, high-performance embedded processor, a main control computer, a human-machine interface, a field bus interface and a data storage unit, wherein the displacement sensor and the force sensor are used for collecting data, the high-performance embedded processor is connected with the displacement sensor and the force sensor, and the human-machine interface, the field bus interface and the data storage unit are connected with the main control computer. According to the system, pull/press signals and displacement-value signals in a press-mounting process can be rapidly and synchronously collected, the pull/press signals and the displacement-value signals respond rapidly, a servo electric cylinder is controlled through a high-speed closed loop, and the accurate press and mounting of the modes of positioning, pressure fixing, pressure limiting and positioning and the like are achieved; meanwhile, the pull/press signals, the displacement-value signals and curve graphs of relations between the pull/press signals and the displacement-value signals can be monitored and analyzed; according to preset constraint conditions, the quality of products is inspected and evaluated in real time in the press-mounting process, defective products can be detected online, and the lean press and mounting are achieved to the maximum degree.
