Problems solved by technology

The first method above is just a simple optical infrared technology method. Infrared rays can only be transmitted within a straight line of sight, and the visible range is narrow. It is easily blocked and interfered by external obstacles, resulting in signal loss, so it is not conducive to long-distance or Looking for the charging stand across obstacles, because the receiving head is on the mobile robot, it is easily interfered by the infrared signal of the external environment, and because the charging stand must be placed next to a fixed object, the coverage of the infrared emission signal is reduced
Although the above second method will not be blocked and interfered by external obstacles, it can only find the approximate location of the charging stand
The above-mentioned third method is more susceptible to the influence of the external environment, occlusion and poor light will lead to recognition errors, and the amount of calculation is relatively large, resulting in a relatively large power consumption for the mobile robot in the process of finding a charging stand

Abstract

The invention discloses a mobile robot charging control system and method. A communication mechanism between a charging seat and a mobile robot is built through wireless communication. Through combining with the azimuth information of the charging seat and robot, the mobile robot can quickly obtains the general azimuth of the charging seat at a moment of starting to search the charging seat, and continuously tries to get close to the charging seat according to the azimuth of the charging seat and the generation azimuth of the robot. The robot is guided onto the charging seat through infrared communication while getting close to the charging seat, thereby achieving butt joint even if the charging seat and the robot are located in different rooms. Through building the wireless communication mechanism between the charging seat and the mobile robot and combining with the geographic azimuths of the charging seat and the mobile robot and infrared signal guide, the system and method can enable the robot to return to the charging seat quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of signal processing and automatic control, in particular to a mobile robot charging control system and method. Background technique [0002] With the improvement of living standards, more and more people desire more personal time in order to enjoy life. However, fast-paced work and heavy housework take up a lot of people's personal time. With the development of science and technology, mobile robots can gradually replace human beings to undertake simple and repetitive physical labor. A considerable part of these robots must have their own batteries to achieve mobility. When the battery is exhausted, the robot will not be able to work, so it is necessary to monitor the power of the robot from time to time. When the power is low to the set threshold or manually When the charging command is activated, the robot must start the mode of searching for the charging station in order to return to the charging statio...
