Contour recognition technology-based high-efficiency and low-cost automatic recharging system and method

Abstract

The invention discloses a contour recognition technology-based high-efficiency and low-cost automatic recharging system and a method. Only one feature module needs to be arranged on a charging seat, and a laser radar and a mobile mechanism are arranged on a mobile platform. A light beam emitted by the laser radar is reflected back when the light beam emitted by the laser radar touches an obstacle.The analysis is carried out through analysis units on the mobile mechanism, so that the contour line of the surrounding environment is obtained. The mobile platform is controlled to move and clean bythe mobile mechanism. Meanwhile, relevant line segments with a feature module are compared and then the position of the charging seat with the feature module is judged. In this way, the mobile platform is automatically returned to the charging seat for being charged according to the position information when the mobile platform needs to be charged. The whole structure is simple, and the control process method is simple. By adopting the laser radar and a radar reflection light analysis unit, the system is not prone to being influenced by dust and the like compared with infrared detection. Meanwhile, the contour recognition technology is adopted, so that the moving position of the mobile mechanism is more rapid and more accurate.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to an automatic recharging system and method for sweeping the floor. Background technique [0002] Automatic recharging technology is widely used in sweeping robots and vacuum cleaners, and is generally equipped with an automatic recharging device, which is also called a "recharging seat". [0003] The automatic recharging of the sweeping robot means that the charging base continuously sends out signals, the receiver on the robot receives the signal, and finally finds the way to "go home". There are many ways to return to the charging technology, such as infrared positioning technology, Bluetooth positioning technology And radar positioning technology, etc., 70% of the models on the market use infrared positioning technology, but this form has many disadvantages. Although infrared positioning has high accuracy, because this kind of light cannot penetrate objects, infrared rays ca...

[0003] The automatic recharging of the sweeping robot means that the charging base continuously sends out signals, the receiver on the robot receives the signal, and finally finds the way to "go home". There are many ways to return to the charging technology, such as infrared positioning technology, Bluetooth positioning technology And radar positioning technology, etc., 70% of the models on the market use infrared positioning technology, but this form has many disadvantages. Although infrared positioning has high accuracy, because this kind of light cannot penetrate objects, infrared rays can only be used in Positioning within the line of sight is just like the infrared ray used by the TV remote control. If something blocks it, the signal will be lost. For the sweeping robot, there will be a certain dust layer during the sweeping process, and when the dust layer is too much, the dust Debris can easily interfere with infrared reception, making it impossible for the sweeping robot to find the charging base

Moreover, the refilling device made of the above-mentioned structure requires complex electronic hardware and high maintenance costs.
