Problems solved by technology

Although this type of technology improves the detection efficiency, it is very easy to identify the normal opening of the elevator on the leveling floor as an abnormal door opening, which leads to false identification / alarms
Moreover, this type of technology only depends on the speed to judge whether the elevator is running, and its recognition accuracy is greatly affected by the accuracy of speed data reporting and the frequency of collection
If there is an error in speed data collection within a short period of time, it is also prone to misidentification / alarming, which seriously affects the accuracy of door opening and elevator detection

Abstract

The invention relates to a door-opening elevator walking real-time detection method fusing multi-sensor data. The method comprises the following steps: a, acquiring door state data, speed data and air pressure data of an elevator in real time; b, judging whether an elevator door is opened abnormally or not according to the door state data; c, if the elevator door is opened abnormally, judging whether the elevator runs or not in the door opening period according to the speed data and the air pressure data at the same time; and d, if the elevator runs in the door opening state, outputting a door opening elevator walking alarm. By means of the detection method, the normal opening condition of the elevator door can be recognized, and therefore false alarms are avoided to a great extent.

Description

technical field [0001] The invention relates to a real-time detection method for door opening and elevator walking by fusing multi-sensor data. Background technique [0002] With the development of urbanization and the trend of adding elevators to old buildings, the use of elevators is also increasing. What comes with it is frequent elevator failures. Among elevator failures, walking with the door open is the most harmful. The reason is that serious accidents such as trapping people and falling into wells are very likely to occur when the door is opened and the ladder is taken. Therefore, the technology capable of real-time monitoring and identification of door-opening and elevator phenomenon and timely prevention has gradually become the focus of attention in related fields. [0003] In the prior art, there are also some technical solutions for preventing or identifying elevators with doors open. For example, some technologies use multiple sets of sensors to directly moni...
