The invention discloses a rockfall monitoring and early warning system and a rockfall monitoring and early warning method based on an MEMS sensing technology. The method comprises the following steps: determining an object: determining a rock object to be monitored through inspection; arranging an instrument: arranging an MEMS micro-motion sensor sub-machine on a monitored rock object, and arranging a data receiving host at a stable and safe position; measuring data: continuously monitoring the stability change of the rock mass, and transmitting and storing test data; data analysis: calculating and analyzing the obtained data; and analyzing the result: helping to judge whether the road can pass or not, and implementing an early warning function. Compared with the prior art, the system has the advantages that the monitoring precision is higher, the real-time performance is better, meanwhile, by adopting the continuous monitoring and wireless transmission technology, remote monitoring is achieved, monitoring pe
