The invention relates to an ultrasound positioning system for an indoor mobile robot. The ultrasound positioning system comprises a positioning system signal emission end, a positioning system signalreceiving end and a central controller. The positioning method comprises the steps of 1, sending a positioning instruction to the system signal emission end on a to-be-positioned robot; 2, emitting anoptical signal after the instruction is received by the positioning system signal receiving end, and starting to time; 3, emitting an ultrasound signal to the positioning system signal receiving endafter the emitted optical signal is received by the positioning system signal emission end; 4, stopping timing when the ultrasound signal is received by the positioning system signal receiving end, and then sending ultrasound propagation time information and current positioning robot number to the central controller; and 5, and sending positioning information to the mobile robot after the information emitted from the positioning system signal receiving end is received and processed by the central controller. By the ultrasound positioning system, the problem that the accurate positioning demandof the indoor mobile robot is difficult to satisfy by satellite positioning under an indoor scene can be effectively solved.
Description
technical field [0001] The invention relates to the technical field of navigation, in particular to an ultrasonic positioning system and positioning method for an indoor mobile robot. Background technique [0002] Most of the existing positioning systems use satellites to locate the target. This positioning technology is widely used, but there are also problems such as low positioning accuracy and limited usage scenarios. In indoor and other confined scenarios, satellite positioning is difficult to meet the target. Accurate positioning needs. Contents of the invention [0003] The purpose of the present invention is to provide an ultrasonic positioning system and positioning method for indoor mobile robots, which can effectively solve the problem that satellite positioning in indoor scenes is difficult to meet the precise positioning requirements of indoor mobile robots. [0004] To achieve the above object, the present invention is achieved in that: [0005] An ultrason...
