Problems solved by technology

[0005] At the same time, the current photoelectric sensor or microwave sensor can only respond to whether an object enters the detection range, but cannot judge the actual size of the object, so it may respond to the entry of abnormal passengers during use, such as animals, infants, etc. , there is a certain security risk
In addition, photoelectric sensors or microwave sensors cannot judge whether there are large areas of passengers stranded at the exit of escalators or moving walks, which may be a potential safety hazard.

Abstract

The invention discloses a passenger detection device for an escalator or a moving walkway and an implementation method thereof. An intelligent distance sensor located at the entrance and / or exit of the escalator or the moving walkway emits multiple beams, and these beams form a detection area; part The beam is reflected by the measured object to the smart distance sensor. The smart distance sensor calculates the vertical distance between the measured object and the entrance or exit of the smart distance sensor based on the round trip time of each beam and the angle between each beam and the entrance or exit of the smart distance sensor. distance to obtain the minimum vertical distance between the measured object and the entrance or exit where the smart distance sensor is located at each time point; the signal processor determines the movement trend of the measured object based on the continuous changes in the minimum vertical distance, and sends a corresponding response to the escalator or moving walkway command signal. The present invention uses a very simple algorithm to use intuitive distance value changes to determine the movement trend of the measured object relative to the entrance and exit of the escalator or moving walkway.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a passenger detection device for escalators or moving walks. Background technique [0002] Escalators or moving walks are widely used in public places such as public infrastructure, shopping malls, and office buildings. With the improvement of energy-saving awareness in the whole society, the energy-saving requirements for escalators or moving walks are also increasing, and the automatic start-stop technology is also improved. The energy-saving effect of escalators or moving walks is improved. Among them, the passenger detection device is a key part to ensure the safe and effective operation of escalators or moving walks. [0003] The current passenger detection device mainly uses photoelectric sensors or microwave sensors installed at the entrances and exits of escalators or moving walks to detect whether there are passengers entering. After a certain time, the escalator or moving wal...
