Abstract

The invention discloses a wireless and magnetic field induction technology combined high precision positioning technology and a corresponding sensor device. The specific technology includes that: (1) a matrix distribution analog Hall voltage detection way is adopted; (2) a wireless radio frequency technology is employed to identify landmark information, and positioning and identification are combined into one; (3) the indoor and outdoor general positioning sensor is not disturbed by rain, snow, thunder, electricity and other environmental factors; and (4) the positioning sensor and method support multi-interface communication and multi-module combination. Compared with current traditional magnetic induction positioning technology, the positioning sensor and method provided by the invention have the advantages of high positioning precision, good stability, good scalability, low cost, concise connection line, and strong anti-interference ability, etc., and are suitable for high precision mobile robot magnetic stripe navigation under various environments.

Description

technical field [0001] The present invention relates to a navigation method and device, in particular to a high-precision positioning sensor and method based on the combination of wireless and magnetic field induction technologies. Background technique [0002] In the research of mobile robot-related technologies, navigation technology is its core technology, and it is also the key technology to realize intelligent and autonomous movement. At present, the mobile robot navigation technology that is widely used at home and abroad is magnetic navigation technology. The robot realizes the navigation movement by sensing the magnetic strip laid in real time. The current magnetic navigation uses switching Hall sensors with a positioning accuracy of 1cm, which is low and can easily cause movement derailment; the positioning module of road signs and the real-time navigation module are located in different parts, with many interfaces and high cost, and the layout of the magnetic induc...
