Abstract

The invention discloses a low-power-consumption axle bearing temperature detecting device for a locomotive, comprising a power supply module, a communication module, a temperature collecting module, a microcontroller and a shielding box. The low-power-consumption axle bearing temperature detecting device collects the temperature from four axle bearing temperature sensors and an ambient temperature sensor connected therewith, and sends temperature data to an upper level processor at regular intervals. In addition, four different alarm modes can be chosen to process the temperature data, and if alarm conditions are met, a corresponding alarm code is sent to the upper level processor. The low-power-consumption axle bearing temperature detecting device for the locomotive provided by the invention has the characteristics of simple structure, wide measuring range, high measuring precision, fast response speed, low power consumption and good reliability.

Description

technical field [0001] The invention belongs to the technical field of locomotive shaft temperature detection, and in particular relates to a low-power consumption locomotive shaft temperature detection device. Background technique [0002] Nowadays, my country's economy is developing rapidly, and high-speed rail, bullet trains, subways and other locomotives are widely used, which greatly facilitates people's lives. When the locomotive is running, it is easy to have an impact with the rail, and the locomotive itself has a large weight and load capacity, which causes the locomotive bearings to heat up and wear. Serious accidents such as derailment and car crashes are caused when the axle wear is serious. Therefore, the safe operation of the locomotive is the premise to ensure the safety of people's lives and property, and the axle temperature of the locomotive is an important parameter for the normal operation of the train. Real-time detection must be maintained. If the axle...
