Abstract

The invention discloses a transformer substation inspection robot track calculation method and device based on inter-wheel differential. A feedback link is added in the track calculation method, track data treated by virtue of Kalman filtering is fed back to a track calculation equation, the self-correction of the equation is realized, and the influence of interference on the track calculation can be effectively alleviated. The track calculation precision is relatively high in a local part, the circuit is simple, the parameter is simple to debug, and the algorithm is easy to realize. The transformer substation inspection robot track calculation method is combined with a magnetic track navigation technology, a magnetic track can be buried in a segmenting manner, the in-situ construction can be effectively reduced, and the cost is reduced; the transformer substation inspection robot track calculation method also can be combined with a GPS global navigation system, in a failure area of the GPS, the track information with high local precision can be outputted, and the weaknesses of the GPS global navigation system can be effectively compensated.

Description

technical field [0001] The invention belongs to the technical field of mobile robot positioning and navigation, and in particular relates to a method and device for dead reckoning of a substation inspection robot based on differential speed between wheels. Background technique [0002] With the in-depth application of substation inspection robots in recent years, complex substation inspection tasks have put forward higher requirements for the reliable and accurate operation of inspection robots in substations. The basis for accurate docking at checkpoints. At present, the technologies used for the position and heading angle information perception of substation inspection robots mainly include the following: [0003] 1. The way of magnetic track course guidance and RFID tag auxiliary positioning. This method combines the magnetic track pre-buried on the ground surface with the magnetic sensor array carried on the robot body to provide real-time heading guidance during travel...
