The present invention discloses a device for monitoring and preventing slump and a processing method thereof. The device includes: an alarm module, a signal collection module, and a signal processing module, wherein the signal collection module is used for collecting human-body posture behavior data and biometrics data； the signal processing module includes a slump detection unit configured to perform analysis processing according to the human-body posture behavior data and biometrics data to judge a state of the human body, and output a help signal to the alarm module when judging that a slump occurs to the human body； and the alarm module generates and outputs help message according to the help signal. The device and method according to the invention, perform slump detection through the human-body posture behavior data and biometrics data, thus the behavior characteristics of the human body are considered effectively, and higher accuracy is achieved.
