Axle power generation device, self-powered sensor and vehicle state information monitoring device

Abstract

The invention discloses an axle power generation device, a self-powered sensor and a vehicle state information monitoring device. The axle power generation device comprises a magnetic-conducting fluted disc and a power generation unit, wherein the magnetic-conducting fluted disc is provided with at least one protruding tooth part or a plurality of protruding tooth parts; the plurality of protruding tooth parts are evenly arranged at intervals; the magnetic-conducting fluted disc is fixed on an axle; the power generation unit comprises a shell, an electromagnetic induction coil, an N-pole permanent magnet and an S-pole permanent magnet; the electromagnetic induction coil is fixed in the shell; the N-pole permanent magnet and the S-pole permanent magnet are arranged at two sides of the electromagnetic induction coil respectively; and the power generation unit is arranged at the position with a preset distance from the outer side of the magnetic-conducting fluted disc. The axle power generation device can be applied to power supply of any vehicle equipment with power supply inconvenience; and power generation, vehicle state detection and vehicle state system monitoring can be achieved under the condition free of external power supply.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to an axle power generation device, a self-powered sensor and a vehicle status information monitoring device. Background technique [0002] The safety of a vehicle is an important indicator of its performance. When designing the safety of a vehicle, it is usually necessary to use sensors that measure various state parameters of the vehicle. However, in some cases, it may be difficult to power the sensor. For example, there are situations where it is necessary to monitor a specific part of an existing vehicle, and that part has not been designed for power supply before. For another example, in terms of railway applications, the continuous increase in railway operation speed makes safety information monitoring more and more important, but currently some railway freight trains do not provide power supply, so electronic sensors have not been popularized on freight trains. As a...
