Abstract

The invention discloses a robot magnetic navigation sensor applied to transformer substation routing inspection and intelligent logistics. The sensor comprises a main control unit, a Hall sensor, a data processing module, an output data identification module and a low power consumption power supply module, wherein the main control unit is used to wake up the Hall sensor, and make the data processing module to carry out data processing on collected information; the Hall sensor is used for magnetic field detection; the data processing module is used for removing a noise and an interference signal in the system; the output data identification module is used for identifying a wave peak or a trough; and the low power consumption power supply module is used for supplying power for the main control unit, a Hall component, and the data processing module. Under conditions of external disturbances and uncertainties, the magnetic navigation sensor can still accurately detect a position of a magnetic strip so that the magnetic strip position detected by an autonomous navigation robot is more accurate, and reliability of a motion path is improved. Simultaneously, a low power consumption work mode is used, work time is prolonged and work efficiency is improved.

technical field [0001] The invention relates to the field of sensors, in particular to a robot magnetic navigation sensor applied to substation inspection and intelligent logistics. Background technique [0002] In terms of substation inspection and logistics in modern smart grids, due to the large work demand and high labor intensity, the manual mode is unsustainable, and the autonomous navigation robot can realize path identification by identifying the magnetic strips laid on the ground, thereby replacing manual power supply. Substation inspection and logistics distribution in the system, so robots with autonomous navigation are increasingly favored by smart grids. [0003] The robot with autonomous navigation has fully demonstrated its superiority in substation inspection and intelligent logistics, that is, it can inspect outdoor high-voltage equipment in unattended substations, complete the inspection and operation of substation equipment, so that the inspection work Th...

Problems solved by technology

[0004] Guidance technology is the key technology of autonomous navigation robots, and magnetic navigation sensors are an important part of guidance technology, which determines its intelligence and motion accuracy. Traditional magnetic navigation sensors use threshold comparison output, because The consistency of each analog Hall sensor is poor, the power consumption is large, and the output has temperature drift. Therefore, a new output method is urgently needed to reduce the power consumption of the sensor.
