The invention discloses a method and a device for monitoring tumble. The method for monitoring tumble comprises: utilizing a mode recognition method, creating a human body tumble behavior recognition model based on a support vector machine to screen standard feature vectors capable of serving as human body tumble judge, and judging the tumble state of the human body through the joint judge of the mode recognition of the support vector machine and the inclination angle threshold. The device is composed of an acceleration sensor, a microcontroller, a GPS (Global Position System) module, a GSM (Global System for Mobile Communications) module, and the like. The method for monitoring tumble is used for monitoring the acceleration and inclination angle data in a tumble process in real time, correctly recognizing the human body tumble state and timely sending the tumble information and direction to family members of the user and nurses of a community hospital to rescue the user in time. According to the invention, tumble detection is more reliable, tumble judging accuracy is improved, individual difference error is effectively reduced and recognition capability of different tumble categories is greatly improved.
