Schematic diagram.
In figure：1st, signal conversion unit 2, control unit 3, driving plate 4, display unit 5, operating unit.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to technical scheme.
A kind of railway DC600 power-supply system driving plates as shown in Figure 1 it is test bed, including signal conversion unit 1,
Control unit 2, (different model) driving plate 3, display unit 4 and operating unit 5；Wherein：Signal conversion unit 1 passes through interface
It is connected with the driving plate 3 of power-supply system；Operating unit 5 is respectively connected with signal conversion unit 1 and control unit 2, control
Unit 2 is connected with signal conversion unit 1；Display unit 4 is connected with driving plate 3.
Display unit 4 include manually display driving plate under static schema and dynamic mode the voltmeter of operating voltage and
Malfunction coefficient lamp is lighted in driving plate failure automatically.
Operating unit 5 is included for selecting to distribute the rotary switch of each model driving plate 3 correspondence operating voltage and being used for
Enabling signal is sent according to aforementioned operation voltage to the button switch of control unit 2.
Signal conversion unit 2 has concentrated the driving plate test condition of five big producers, i.e.,：The various driving plates of each producer are carried out
Interface concentrationization unification (is concentrated all driving plate interfaces, and is unified on a testing equipment panel), by different driving
The connectivity port of plate 3 is converted into unified pcb terminal interface, is referred to by the work of the various driving plates 3 of the controlled output of control unit 2
Order, and output voltage parameter is detected, when a failure occurs it, break down signal.Various driving plates are realized by operating unit 5
Signal is distributed, specifically：
Operating unit 5 is mainly used for distributing the operating voltage of the driving plate 3 of each model and starts to recognize, first by behaviour
Make the operating voltage of the driving plate 3 of the rotary switch selection various models of distribution of unit 5, then by the band lamp of operating unit 5
The button switch of instruction sends enabling signal to control unit 2, and signal conversion unit 1 is carried out for the driving plate 3 of different model
Interface unification conversion, and transmit control unit 2 send to driving plate 3 enabled instruction and for transmit driving plate 3 export to
The voltage parameter of display unit 1 and control unit 2；Control unit 2 is then used to recognize the model of various driving plates 3, monitoring signals
The voltage parameter of the feedback of converting unit 1, and judge whether driving plate 3 breaks down；The voltmeter of display unit 4 is used to show drive
Dynamic plate 3 start before after (static schema) and startup (dynamic mode) output voltage parameter.
In the present embodiment, testing stand can to iron section, just remote, new reputation, strain when and Hua Shi (but being not limited to this five kinds) it is internal
(iron section driving plate (model KC2) carries out testing experiment to the driving plate 3 of power supply, and monitors output parameter, judges whether plate is sent out
Raw failure.
Iron section driving plate (model KC2), just remote driving plate (model ZYY67-02-52-01-00G), prestige driving plate
(model CDXX05/15 and CDXX16), magnificent scholar's driving plate (model HS3.226.361MX and HS7.820.422) and strain
Institute's driving plate (TET313B-11-01-GY)) carry out performance test.The selecting switch of operating unit 5 is to signal conversion unit first
1 (i.e. input/output board) distributes the operating voltage of driving plate 3, driving plate 3 is worked in a static mode, and now driving plate 3 is defeated
The a certain voltage characteristic for going out delivers to display unit 4 (i.e. voltmeter) and shows voltage parameter by input/output board, while by the electricity
Pressure parameter sends to control unit 2 (i.e. master control borad) and carries out data diagnosis, and whether just driving plate 3 under judging now static schema
Often, after confirming the board static state fault-free of driving plate 3, the start button of operating unit 5 sends enabled instruction, now driving plate 3
Work voltage parameter in a dynamic mode can change, and can be judged with visual inspection by the voltmeter of display unit 4, together
When may also pass through master control borad and carry out data diagnosis, judge its output characteristics whether failure, confirm automatic after failure to send failure and refer to
Show signal, show that the fault-signal occurs automatically by display unit 4.
As shown in Fig. 2 by the above-mentioned test bed performance test for iron section driving plate, driving plate 3 is connected first
It is connected on input/output board, now controls K1, K4 to close by operating unit 5, the operating voltage of+5V and+24V is by input
Output board delivers to driving plate 3, and driving plate 3 is in static schema, and under the pattern, six road output voltages of driving plate 3 should be negative
8-10V between, the output voltage parameter of each port of this driving plate is sent to six voltmeters and shows respectively through input/output board,
Master control borad receives six road voltage datas to being analyzed contrast simultaneously, judges whether the board of driving plate 3 under static schema is normal.
If abnormal, faulting instruction is sent, light corresponding malfunction indicator lamp.If the data under static schema are normal, by behaviour
The TK buttons for making unit 5 send driving plate enabled instruction, and now output voltage parameter should have obvious numerical value change, Ying Youyuan
Carry out the voltage that anti-phase 8-10V is changed into positive, its value should be between 1.8-3V.Shown by six voltmeters of display unit 4 respectively
Show six road output voltages, now master control borad receives six road voltage parameters and ratio is analyzed to it again, judges the drive after starting
Whether dynamic plate is normal, bitter abnormal, then send faulting instruction, lights corresponding malfunction indicator lamp.If voltage parameter is consistent, lead
Control plate does not send indicating fault, that is, represent that the test of the plate of driving plate 3 is normal.Just remote, new reputation, strain institute and magnificent scholar in addition to iron section etc.
Driving board test also refers to the embodiment analogizes is carried out.
As can be seen that whether driving plate 3 can intuitively check its output voltage parameter very much with after startup before activation
Balance is consistent, and whether logical master control borad is crossed to be diagnosed and broken down.Not only whole process is easy to operate simple, and soon
The accurate quality for judging plate, substantially increases operating maintenance efficiency.And the test method does not obviously need each producer's power supply system
System and electric power system are supported, and also do not receive place and time restriction, and based on integrated and compatible advantage, cost substantially drops
It is low.
Testing stand of the invention can concentrate five test conditions of the driving plate 3 of producer's (but being not limited only to this), simulation
The course of work of driving plate 3, carries out energizing test, greatly without the driving plate 3 after maintenance is filled into corresponding producer's power source internal
The big workload for reducing plate experiment.The testing stand can completely check every input and the output parameter of driving plate, on the one hand
Each item data shown by display unit, maintenance personal can full apparent ground understand the overall work state of plate and worked
Journey is clearly understandable, and the testing stand is simple to operate：The correspondence that driving plate 3 is connected to signal conversion unit 1 is connect first
On mouth, secondly the rotary switch of operating unit 5 shares out the work power supply；The corresponding button switch of last push unit 5, starts
Driving plate 3 is started working.
As described above, being explained to embodiments of the invention, it is clear that as long as essentially without this hair of disengaging
Bright inventive point and effect, will be readily apparent to persons skilled in the art deformation, also be all contained in guarantor of the invention
Within the scope of shield.
