Method and system for determining the position of a mobile device with respect to a stationary device, in particular of a battery-operated dust collecting robot with respect to an accumulator - charging device, stationary apparatus and mobile device

摘要

A method for determining the position of at least one mobile device, in particular a self-propelled accumulator-operated dust collecting robot, from its respective position of a derived therefrom travel path to a stationary apparatus, in particular a battery charging device - can be fastened using transmission signals, the of the stationary device with an at least one rotating transmission characteristic is to be transmitted, and while applying a reference signal from the stationary device, in relation to the the position of the aforementioned transmission signals is fixed, wherein in the mobile device of the relationship between the orientation of the individual transmitted signals and the reference signal is known, and wherein in the mobile device, its position to the stationary unit from the time difference between the time of the reception of the rotating transmission signal with maximum field strength and the transmission of the reference signal is determined, characterized by the,that of the mobile device (ro) first a request signal in the form of an ultrasonic signal (u.s. pat. no.) to the stationary unit (bs) is emitted,that of the stationary unit (bs)..
