Embodiment Construction

[0086] Further illustrate the present invention below in conjunction with accompanying drawing.

[0087] Refer to attached Figure 1-11 , the escalator energy saving and safety monitoring system based on omnidirectional computer vision includes omnidirectional visual sensors, voice prompt units and microprocessors; the omnidirectional visual sensors are used to acquire video images including the entire escalator on both sides, and the microprocessor is used to Detect the number of people who are going to get on the escalator and those who are already on the escalator, analyze the status of the people on the escalator, the running status of the escalator, count the number of people entering and leaving the escalator, and control the stop and operation of the movement; the voice prompt unit is used to Various unsafe or dangerous states are played by voice;

[0088] In order to effectively obtain all video image information including the entire escalator and the entrance and exi...

Abstract

An escalator energy-saving and safety monitoring system based on all-round computer vision, including a microprocessor, an all-round vision sensor and an escalator PLC controller. At the same angle, the omnidirectional visual sensor is connected to the microprocessor, and the microprocessor is connected to the PLC controller of the escalator. The curves of the reflective mirror and the double catadioptric mirror are designed according to the average resolution in the horizontal direction. The lens of the camera component is placed at the viewpoint behind the primary catadioptric mirror and obtained by the secondary catadioptric mirror through the small hole of the primary catadioptric mirror. The reflected panoramic image; the transparent outer cover supports the primary catadioptric mirror surface and the secondary catadioptric reflective mirror surface; the invention has good energy saving performance and can realize good safety monitoring.

Description

technical field [0001] The invention belongs to the application of omnidirectional vision sensor, computer vision, automatic control and other technologies in aspects of safety and energy saving of escalators. Background technique [0002] Escalators are inclined, powered escalators used to carry passengers up or down. The steps move horizontally at the passenger entrance, and then gradually form a ladder; when approaching the exit, the steps gradually disappear, and the steps move horizontally again. Escalators are one of the equipment for efficiently transporting passengers in public places, and are widely used in shopping malls, hotels, airports, stations and other places. Escalators are widely used for their strong conveying capacity and convenient use. Compared with the vertical elevator, the defects of the escalator are very obvious, (1) the waste of electric energy in the case of idling; (2) the occasional retrograde behavior of the escalator is easy to cause injury...
