Embodiment 1

[0037] The working principle of the conventional locomotive braking resistor is attached figure 1 As shown; when the vehicle starts to brake with the braking resistor, the train will turn on the IGBT overvoltage chopping, and use the locomotive braking resistor to consume the regenerative energy of the IGBT chopping; and then use the fan to dissipate the heat of the locomotive braking resistor into the air; However, as the regenerative energy is dissipated on the braking resistor in the form of heat energy, the temperature of the resistor will gradually rise. It is necessary to monitor the braking resistor of the locomotive in real time to prevent the temperature of the braking resistor of the local locomotive from rising too fast, resulting in failure. Otherwise, it will seriously affect the safe operation of the vehicle traction system.

[0038] In order to obtain accurate braking resistor temperature, the present invention arranges a temperature sensor 2 in the body of the ...

Embodiment 2

[0052] The principle of the second embodiment is basically the same as that of the first embodiment, except that the specific structure and processing methods are different; an intelligent monitoring method for the failure of the braking resistor of the locomotive, through the braking resistor on the body surface of the braking resistor of the locomotive Install a temperature sensor, attach the temperature sensor to the body surface of the braking resistor, directly collect the temperature value on the surface of the braking resistor element, convert the collected temperature value into a temperature electrical signal, and send it to the traction control through the CAN bus The unit (DCU) performs intelligent identification and monitoring. At the same time, an air duct air temperature sensor is installed at the outlet or entrance of the ventilation duct of the braking resistor. The air temperature in the air duct is detected by the air duct air temperature sensor, and the detect...

Abstract

An intelligent monitoring method for the braking resistor failure of a locomotive. A temperature sensor is installed in the body or on the surface of the braking resistor element of the locomotive braking resistor or around the surface to collect the temperature signal on the braking resistor element. Air duct air parameter detection sensors are installed at the inlet or outlet of the air duct, and the air parameter information in the air duct of the locomotive braking resistor is collected by the air duct air parameter detection sensor, and the temperature signal and air parameter information are sent to the traction control unit through the CAN bus Carry out intelligent identification and monitoring, and determine the status of the locomotive braking resistor through the intelligent identification of the traction control unit. The invention obtains the temperature signal and air parameter information by detecting the braking resistor element, and intelligently recognizes and judges the operation status of the locomotive braking resistor through the temperature signal and air parameter information, effectively protecting the operation safety of the locomotive braking resistor, and is suitable for various Popularization and application of locomotive braking resistors.

Description

technical field [0001] The invention relates to a component monitoring method of a locomotive brake system of an electric locomotive, in particular to an intelligent monitoring method for a brake resistor failure of a locomotive; the intelligent monitoring method for a brake resistor failure of a locomotive and the grounding resistance can effectively reduce the The invention relates to the occurrence of a resistance fault; it belongs to the technical field of electric locomotive manufacturing. Background technique [0002] At present, most electric locomotives use resistance braking. Using resistance braking, the original traction motor that drives the wheelset is converted into a generator. The inertia of the train is used to drive the rotor of the motor to rotate to generate electricity, thereby generating reverse torque and consuming the train. Kinetic energy, to achieve the purpose of braking. The electric current from the motor passes through specially set resistance ...
