Description
Technical field
The present invention relates to locomotive technology field, and in particular to a kind of locomotive traction motor temperature redundancy monitoring method.
Background technology
In the prior art, in order to realize the control and protection to locomotive traction motor, in the stator core of traction electric machine
Temperature sensor is installed, the motor temperature collected is sent to converter control system.When the temperature of monitoring reaches threshold value
When, send temperature alarming.Two paths of data passage generally is used, is used all the way as control, another way is as spare, to improve system
Reliability.But in practical applications, temperature sensor may break down, or the electromagnetism that while being subject to locomotive operation is accidental
Interference.These can make system cause to judge by accident.In addition, when difference occurs for two paths of data passage, system can not be to the effective of data
Property carries out judgement choice, so as to lose spare meaning.
The content of the invention
The purpose of the present invention is exactly to overcome the deficiency of the above-mentioned prior art, there is provided a kind of locomotive traction motor temperature redundancy prison
Survey method.
The technical solution adopted in the present invention is a kind of locomotive traction motor temperature redundancy monitoring method, using two ways
According to channel monitoring motor stator temperature, it is characterised in that take the following steps：
A. design temperature refers to value function T3 and -50 DEG C of normal temperature data area~250 DEG C；
B. gather at the same time temperature data T1 and T2, traction motor current, ventilation quantity that two paths of data passage detects respectively and
Environment temperature, and calculate T3；
C. if T1 and T2 be not in normal temperature data area, it is effective motor temperature value to take T3, and alarm T1 and
T2 circuit-switched data channel temperature sensor faults；
D. if T1 is in normal temperature data area, for T2 not in normal range (NR), it is effective motor temperature value to take T1, and
Alarm T2 circuit-switched data channel temperature sensor faults；
E. if T2 is in normal temperature data area, for T1 not in normal range (NR), it is effective motor temperature value to take T2, and
Alarm T1 circuit-switched data channel temperature sensor faults；
F. if T1 and T2 are in normal temperature data area, take in T1 and T2 that Error Absolute Value is smaller compared with T3
For effective motor temperature value, or take change rate Error Absolute Value compared with T3 change rates in T1 and T2 less for effectively electricity
Machine temperature value.
The solution of the present invention can be filtered from extraneous interference signal, reduce the mistake to locomotive traction motor temperature
Report, improves system reliability, so as to reduce machine breaking rate, improves locomotive efficiency.
