Accurate-positioning navigation system of autonomous mobile device

Abstract

The invention discloses an accurate-positioning navigation system of an autonomous mobile device. The accurate-positioning navigation system is characterized by comprising an RFID (Radio Frequency Identification Device) and infrared transmitting device and an RFID and infrared receiving device, wherein the RFID and infrared receiving device is arranged in the autonomous mobile device, the RFID and infrared transmitting device is arranged at a positioning point, and the distance between the RFID and infrared transmitting device and the RFID and infrared receiving device is less than 200m. According to the invention, the defects that the positioning distance of the traditional single infrared device is small and the positioning is not easy to be processed are remedied; and due to the integration of the RFID and infrared rays, the quick and accurate positioning can be carried out, and the accurate-positioning navigation system of the autonomous mobile device, disclosed by the invention, has the advantages of simple structure, accurate data, high processing speed, low requirement on a hardware, low cost, high reliability as a rotating component is free and capability of ensuring the free motion and accurate positioning and navigation of the autonomous mobile device within a covered range.

Description

technical field [0001] The invention relates to an autonomous navigation device, in particular to an accurate navigation system for autonomous mobile equipment. Background technique [0002] Intelligent autonomous mobile devices, such as robots, need to locate and navigate autonomously while moving. Especially the precise navigation of indoor robots serving homes and factories is a difficult problem. The current common navigation method is line-following navigation, that is, by setting a guide line on the ground and sensing the guide line through sensors such as light, magnetism, and electric field to realize navigation. The disadvantage is that the equipment using this technology can only follow the line. Walking, lack of flexibility; Another navigation method is inertial navigation, which is realized by gyroscope and electronic compass. The disadvantage is that there is error accumulation; another navigation method is through image recognition and image matching navigatio...
