Abstract

The invention discloses a light locating system used for a cleaning robot. The light locating system comprises a light emitting device, a signal receiver arranged on the cleaning robot and a microcontroller. The light emitting device comprises a plurality of luminous sources, each luminous source loads a recognition code of itself into a light signal to be transmitted, and the recognition codes are position information of the luminous sources in the light emitting device. The signal receiver is used for receiving the light signals from the luminous sources. The microcontroller is used for conducting calculating processing on the strength and the time of the light signals, received by the signal receiver, of at least three of the luminous sources to obtain the spatial position of the signal receiver. According to the light locating system, the luminous sources realize an indoor locating function while being used for lighting, therefore, the indoor spatial position of the cleaning robot is determined and automatic cleaning work for preset specific lines is completed. A locating method is simple, convenient to implement and high in locating precision, and greatly reduces the housework burden of people.

Description

technical field [0001] The invention belongs to the field of optical communication technology and the field of household cleaning, and in particular relates to an optical positioning system and a positioning method for a cleaning robot. Background technique [0002] A cleaning robot is an electric cleaning device equipped with a microcomputer system, which can clean a specific part or all of the room according to people's settings. The positioning technology of the cleaning robot is the core technology of the entire cleaning robot. Existing cleaning robots use position sensors for positioning. However, due to the irregular placement of furniture and other objects in ordinary households, it is difficult to locate the position sensors. Positioning errors often occur, resulting in suction leakage. On the other hand, with the continuous promotion of LED environmental lighting technology, it is an irreversible trend for LED lighting systems to replace ordinary fluorescent lamps....
