The rolling screw transmission mechanism is a key transmission component of the servo mechanism. Monitoring its operating state is crucial for the normal operation of the servo control system. Currently, there are still difficulties in the state monitoring of rolling screw transmission mechanisms, such as low integration and wiring difficulties. A multi-parameter wireless micro-nano sensing monitoring system for rolling screw transmission mechanisms is designed. The sensing module, MCU module, wireless module and power management module are integrated in this system, which can be integrated with the nut of the rolling screw transmission mechanisms directly and flexibly, improving integration and reducing wiring complexity. The sensing module contains three types of MEMS sensors for temperature, acceleration, and acoustics to meet the condition monitoring requirements of multi-point distributed and multi-parameter sensing on the surface and interior of the nut. This system has advantages of small size, easy installation, flexibility and high integration, effectively monitoring the working state of rolling screw transmission mechanisms.
