Description
Technical field
The present invention relates to rail transit electrical equipment fields, are applied to EMU, high-speed railway, iron more particularly, to one kind
Traction convertor (CI) the power module overtemperature recording device of the rail traffic vehicles such as road locomotive, city rail vehicle, railcar and
Method.
Background technology
EMU CI (traction convertor) generally includes 5 power modules, and the wherein quantity of rectification module is 2, and inverse
Become the quantity of mould as 3, as shown in the module position schematic diagram of attached drawing 1.After overtemperature occurs for EMU CI modules, traction current transformation
Device can only record overtemperature state, but it is which specific module breaks down in 5 power modules that cannot be accurately located.
And when EMU is when torridity summer or traveling are in torrid areas, at any time may CI happened power module overtemperature alarm failure,
And after there is alarm, which can entirely be removed, and so as to which motor-car be made to lose partial power, influence normal row
Vehicle process, leads to Train delay, has seriously affected punctuality rate and the safety of EMU operation.Since power module overheats
Some specific power module cannot be navigated to during alarm condition, and generally dynamic temperature alarm occurs in operation, it is more difficult to
It is diagnosed.Even technical staff, which adds, multiplies observation, specific malfunctioning module can not still be accurately positioned when failure occurs.
In the prior art, overheat overtemperature alarm is occurred for traction convertor power module, be typically only capable to until motor-car
After group storage, after experimental is in addition to reasons such as deashing, heat dissipations in library, just following method can be taken to be handled：
(1) first method is：Experiment of reaching the standard grade is carried out after the power module of traction convertor is replaced one by one, it can when most
5 replacements processing can be carried out, and train is needed to carry out 5 on-line runnings.This method needs one by one to carry out power module
It replaces, motor-car may at most need on-line running 5 times and carry out 5 processing, could thoroughly solve to handle failure well, but in reality
In situation, high ferro passenger traffic EMU does not allow to operate with failure.
(2) second method is：Disposable all 5 power modules for replacing traction convertor, and it is usual one it is whole
Flow module weighs 185kg, and inverter module then weighs 110kg.This method is although perfectly safe, but needs disposable replacement 5
A power module, the expensive of module, weight are larger, for per failure, 5 modules need to usually prepare 2,000,000 yuan of left sides together

S126：Cycle performs step S123~step S125.
The power module overtemperature alarm information display section of overtemperature recording device 20 uses dynamic scanning displaying method, and LED is shown
Show that the segment encode of program, position code display are employed as the form that nested subroutine supplies main program to call.In every light-emitting diode display all
It sweeps after going over, is returned to main program.It is stored if processing input signal directly carries out data to data storage cell 4, it is first
It calls and shows scanning imaging system, then the dynamic scan of LED digital displays is realized by calling the program repeatedly.It is designed in program
There is 6 tunnels (spare 1 tunnel) input signal, after the temperature relay triggering of traction convertor, set in data storage cell 4
6 addresses store data, can re-read the action state recorded in operation after a loss of power.I2C buses include starting, start
Signal, end signal, clock signal write a byte data, the process of one byte data of reading is designed to as general sub- journey
Sequence, in order to be called at any time in main program.The process that 4 data of data storage cell send and receive response bits is put into subprogram
In, can program structure be further simplified in this way.When the module overtemperature alarm for coming from traction convertor temperature relay
After action, overtemperature recording device 20 inputs a high level signal, by being depressured, filtering, Phototube Coupling and Shape correction, eliminates
After most of signal interference, then signal-obtaining carried out by processor 1.Processor 1 carries out 6 tunnel input signals using 6 I/O
It reads, resets one I/O mouthfuls of progress signal processing of key assignments, complete the identification of input signal and keyboard, pressed according to identifying
The key assignments of key completes the calling of subprograms corresponding.Display button also distributes an I/O mouthfuls of progress signal processings, completes signal
It has been shown that, according to the key assignments of institute's key range, completes the calling of subprograms corresponding.
It is a complete process that input signal and button, which are never triggered to triggering and release, when defeated there are one signal
Enter when triggering often with interference signal, once there is interference to come, false triggering process may be caused, this is the feelings for not allowing to occur
Condition.These interference signals are filtered out, but can increase the volume of hardware cost and hardware circuit using capacitance under normal circumstances.Cause
This, these interference signals are removed in the specific embodiment of the invention using the method for software filtering.Under normal circumstances, one it is defeated
Entering signal or push button signalling, always there is certain interference signals at the time of firm triggering, have been put into the shape stablized later
State.During programming, to more than input signal Time delay 5ms, so as to avoid the region of interference signal, then detect once,
To determine whether trigger signal really triggers, output one at this time is set to high level or low level.If signal is overturn in 5ms
Or lose, then prove that input or push button signalling at this time are the false triggerings caused by interference signal, processor 1 will be given up
This triggering identification process, so as to greatly improve the reliability of system.
After EMU power module overtemperature record system is completed according to preceding method, need to adjust system
Examination.At this point, first by EMU power module overtemperature record system connection DC100V power supplys, the input fortune of overtemperature recording device 20
Whether normal row tests static energization.Then, simulation comes from the power module overtemperature alarm trigger signal of traction convertor,
Signal transition line input DC100V trigger signals between CNS8 plugs and CNS8 sockets, digital-scroll technique unit 6 can be shown
Whether corresponding power module triggers.If digital-scroll technique unit 6 is shown " nb3=0002 " at this time, then it represents that inversion U phase module temperature
Relay is spent to trigger 2 times.The status displaying information cycle alternation of digital-scroll technique unit 6 is shown, a state was shown every one second,
Status details are as shown in table 1 below.
