Abnormal tumbling detection system and method for special crowds

Abstract

The invention relates to an abnormal tumbling detection system and method for special crowds. The detection system comprises a master control unit as well as a static detection unit, a physiological parameter detection unit, a storage unit, a computing unit and a warning device which are connected with the master control unit, wherein the static detection unit detects the motion state of a detected person in real time and sends a detection result to the master control unit; when the person is detected to be in a static state, the master control unit controls the physiological parameter detection unit to detect physiological parameters of the detected person and stores the detected physiological parameters through the storage unit, the computing unit performs processing and analysis according to the stored physiological parameters and judges the safety state of the detected person according to a set danger state judgment index, when the detected person is judged to be in a dangerous state, the warning device gives out an alarm. Otherwise, the warning device does not operate. Compared with the prior art, the detection system and method have the advantages of being high in detection accuracy and stability, high in practicability and the like.

Description

technical field [0001] The invention relates to a detection system and detection method for abnormal falls, in particular to a detection system and detection method for abnormal falls aimed at special groups of people. Background technique [0002] In recent years, falls have occurred continuously in our country, which has aroused widespread concern in the society. Accidents mostly happen to older people. According to the 2014 Statistical Bulletin on National Economic and Social Development issued by the National Bureau of Statistics, my country has entered the aging process, and the proportion of the elderly in society is increasing year by year. As a vulnerable group in society, the elderly should receive more attention, but the contradiction is that with the acceleration of modernization, the rapid development of society, and the continuous acceleration of the pace of life, the pressure on young people is also increasing At the same time, with the impact of population p...

Problems solved by technology

[0004] Nowadays, many scholars at home and abroad have proposed many schemes for the detection of falls. As a behavioral action, falls are highly uncertain and complex. The existing detection methods are based on the undeterministic behavior of falls. Carry out direct detection to judge the fall behavior. However, there are many interferences in the detection process, so the accuracy and stability of the detection are relatively poor.
