Monitoring system and method for abnormal conditions in elevator car

Abstract

The invention discloses a monitoring system for abnormal conditions in an elevator car, comprising at least one 3D somatosensory photography device arranged in the elevator car, and the 3D somatosensory photography device sends the collected original sensing data stream to a signal processing device; The signal processing device judges whether the passenger's behavior is abnormal or whether the passenger is in a dangerous state; when the signal processing device determines that the passenger's behavior is abnormal or the passenger is in a dangerous state, it sends an indication signal to the emergency processing device. The present invention is based on 3D somatosensory photography technology, which can not only enable passengers in accidents to be rescued in time, but also reduce the difficulty of rescue of trapped persons, and at the same time reduce and prevent the occurrence of violent incidents among passengers in the elevator car. The invention also discloses a method for monitoring abnormal conditions in the elevator car.

Description

technical field [0001] The invention relates to a monitoring system for an elevator, in particular to a monitoring system for abnormal conditions in an elevator car. The invention also relates to a method for monitoring abnormal conditions in the elevator car. Background technique [0002] According to the sixth census data, by the end of 2013, China had 202.43 million people aged 60 and over, accounting for 14.9% of the total population; and 131.61 million people aged 65 and over, accounting for 9.7% of the total population. China is entering an aging society, showing a trend of large elderly population base, rapid growth, aging, disability, and empty nests. China's existing elderly population has exceeded 160 million, and it is increasing at a rate of nearly 8 million per year. Experts predict that by 2050, China's elderly population will reach one-third of the total population, and the number of elderly people who are dying without children will reach 79 million.

Problems solved by technology

[0007] Although this type of monitoring system can reduce the occurrence of violent behavior in the car to a certain extent, it can only detect violent crimes among passengers, and the monitoring device needs to be activated only when it is determined that there are two passengers in the elevator.

When a single passenger suffers sudden illness, leaning, fainting and other accidents, this kind of monitoring system does not start the monitoring work, which will delay the passenger's rescue time

[0008] At the same time, because this kind of monitoring system uses the comparison of single-frame image pixels, it can only judge the mutual movement of objects as a whole. Although there are sensors such as voice and load to assist in the judgment, it is still difficult to detect the threat of a passenger holding a knife or several Fights and threats of violence between passengers who are already close to each other, but at the same time, it is easy to mistake the frolicking between passengers (children) and the behavior of passengers carrying goods as violence, which greatly reduces the reliability of the monitoring system
