Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0021] An escalator safety detection device in one embodiment, such as figure 1 shown, including:
[0022] The infrared sensor and the camera are used to obtain the sampling image of the escalator, and detect the background temperature of the escalator with no one on the escalator. The sampling image of the escalator includes the sampling image of the unmanned escalator, the sampling image of one person on the escalator and the real-time sampling image of the escalator;
[0023] The image and infrared processing controller is used to calculate the temperature rise of on...

The invention discloses an escalator safety detection device and method. The method includes the steps of obtaining a sampled image showing that no one is on an escalator, a sampled image showing that one person is on the escalator and real-time sampled images of the escalator through an infrared sensor and a camera, detecting the background temperature when no one is on the escalator, calculating the temperature rise of one person relative to the background temperature of the escalator through an image and infrared processing controller according to the showing that one person is on the escalator, and judging whether a passenger is held up or gets stuck or falls on the escalator or not according to the real-time sampled images of the escalator, the sampled image showing that no one is on the escalator and the rise of one person relative to the background temperature of the escalator. According to the escalator safety detection device and method, information is collected through the infrared sensor and the camera, the image and infrared processing controller judges whether the abnormal condition happens to the escalator or not according to the collected information, corresponding processing is conducted according to the judgment result, accidents can not be extended, and safety of passengers on the escalator is ensured; meanwhile, by combining image processing with infrared matrix sampling, detection accuracy is improved, and the escalator safety detection device and method are suitable for application.
Description
technical field [0001] The invention relates to the technical field of escalators, in particular to an escalator safety detection device and method. Background technique [0002] With the development of the economy, people's living standards are gradually improving, and escalators are used more and more in daily life, which brings people a lot of convenience, but also presents many safety hazards, such as passengers stranded on the escalator , blocking and falling, often cause great injury to people who take the escalator. In order to ensure the safety of passengers on the escalator, regular maintenance is required when using the escalator. At the same time, some detection equipment is required to reflect its operating status at any time during operation. There is no mature technology in the prior art that can detect situations such as passenger retention and falls, which seriously affects the safe use of escalators. Contents of the invention [0003] Based on the above ...
