Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
A kind of railway DC600 power-supply system drive plate as shown in Figure 1 test bed, comprises signal conversion unit 1, control module 2, (different model) drive plate 3, display unit 4 and operating unit 5; Wherein: signal conversion unit 1 is connected with the drive plate 3 of power-supply system by interface; Operating unit 5 is connected with control module 2 respectively with signal conversion unit 1, and control module 2 is connected with signal conversion unit 1; Display unit 4 is connected with drive plate 3.
Display unit 4 comprises the voltage table of manual display driver plate operating voltage under static schema and dynamic mode and automatically lights malfunction coefficient lamp when drive plate fault.
Operating unit 5 comprises and distributes the rotary switch of the corresponding operating voltage of each model drive plate 3 and the pushbutton switch for enabling signal being sent to according to aforementioned operation voltage control module 2 for selecting.
Signal conversion unit 2 has concentrated the drive plate test condition of five large producers, that is: multiple for each producer drive plate is carried out unified (the concentrated all drive plate interfaces of interface concentrationization, and be unified on a checkout equipment panel), convert the connectivity port of different driving plate 3 to unified pcb terminal interface, the work order exporting various drive plate 3 is controlled by control module 2, and detect output voltage parameter, when a failure occurs it, break down signal.The signal being realized various drive plate by operating unit 5 is distributed, specifically:
Operating unit 5 is mainly used for the operating voltage of the drive plate 3 distributing each model and starts identification, first the operating voltage of the drive plate 3 distributing various model is selected by the rotary switch of operating unit 5, then the pushbutton switch indicated by the band lamp of operating unit 5 sends enabling signal to control module 2, signal conversion unit 1 carries out the unified conversion of interface for the drive plate 3 of different model, and transmit control unit 2 is sent to the enabled instruction of drive plate 3 and exports the voltage parameter of display unit 1 and control module 2 for transmitting drive plate 3 to; Control module 2 is for identifying the model of various drive plate 3, and the voltage parameter that monitor signal converting unit 1 is fed back, and judges whether drive plate 3 breaks down; The voltage table of display unit 4 is for (static schema) before display driver plate 3 startup and the output voltage parameter starting rear (dynamic mode).
In the present embodiment, testing table can to when iron section, just far away, new reputation, strain and the drive plate 3 of Hua Shi (but being not limited to these five kinds) internal electric source (iron section drive plate (model is KC2) carries out testing experiment, and monitor output parameter, judge whether plate breaks down.
Iron section drive plate (model is KC2), drive plate (model is ZYY67-02-52-01-00G) just far away, prestige drive plate (model is CDXX05/15 and CDXX16), magnificent scholar's drive plate (model is HS3.226.361MX and HS7.820.422) and strain institute drive plate (TET313B-11-01-GY)) carry out performance test.First the selector switch of operating unit 5 distributes the operating voltage of drive plate 3 to signal conversion unit 1 (i.e. input/output board), drive plate 3 is made to work in a static mode, the a certain voltage characteristic that now drive plate 3 exports is delivered to display unit 4 (i.e. voltage table) by input/output board and is shown voltage parameter, this voltage parameter is sent to control module 2 (i.e. master control borad) simultaneously and carries out data diagnosis, judge that now whether drive plate 3 is normal under static schema, after confirming the static non-fault of the board of drive plate 3, the start button of operating unit 5 sends enabled instruction, the voltage parameter that now drive plate 3 works in a dynamic mode can change, can be judged by visual inspection by the voltage table of display unit 4, also caning be passed through master control borad carries out data diagnosis simultaneously, judge its output characteristics whether fault, automatically fault indication signal is sent after confirming fault, automatically show this fault-signal by display unit 4 to occur.
As shown in Figure 2, by above-mentioned test bed for the performance test to iron section drive plate, first drive plate 3 is connected on input/output board, now by operating unit 5 control K1, K4 closes, namely the operating voltage of+5V and+24V delivers to drive plate 3 by input/output board, drive plate 3 is in static schema, under this pattern, six road output voltages of drive plate 3 should be between the 8-10V of negative, the output voltage parameter of each port of this drive plate is sent to six voltage tables through input/output board and shows respectively, master control borad receives six road voltage datas to carrying out analysis contrast simultaneously, judge that whether the board of drive plate 3 is normal under static schema.If abnormal, then send faulting instruction, light corresponding malfunction indicator lamp.If the data under static schema are normal, then send drive plate enabled instruction by the TK button of operating unit 5, now output voltage parameter should have obvious numerical value change, and should be become the voltage of positive from originally anti-phase 8-10V, its value should between 1.8-3V.Six road output voltages are shown respectively by six voltage tables of display unit 4, now master control borad again receives six road voltage parameters and carries out analysis ratio to it, judges that whether the drive plate after starting is normal, bitter abnormal, then send faulting instruction, light corresponding malfunction indicator lamp.If voltage parameter is consistent, then master control borad does not send indicating fault, namely represents that the test of drive plate 3 plate is normal.The drive plates such as the reputation just far away, new outside deironing section, strain institute and magnificent scholar are tested also to analogize with reference to this embodiment and are carried out.
Can find out, whether drive plate 3 before activation with after startup can to check whether its output voltage parameter balances very intuitively consistent, and lead to master control borad and crosses to carry out diagnosing and break down.Not only whole process operation is convenient and simple, and accurately judges the quality of plate soon, substantially increases operating maintenance efficiency.And this test method does not obviously need each producer power-supply system and electric power system to support, also not by place and time restriction, based on integrated and compatible advantage, cost obviously reduces.
Testing table of the present invention can concentrate the test condition of the drive plate 3 of five producers's (but being not limited only to this), the course of work of analog-driven plate 3, carry out energizing test without the need to the drive plate 3 after maintenance is filled to corresponding producer's power source internal, substantially reduce the workload of plate test.The complete every input and output parameter of checking drive plate of this testing table energy, the every data shown by display unit on the one hand, overall work state and the course of work of maintenance personal's energy full apparent ground understanding plate are clear understandable, secondly and this testing table is simple to operation: be first connected to by drive plate 3 on the corresponding interface of signal conversion unit 1, the rotary switch of operating unit 5 shares out the work power supply; The corresponding button switch of last push unit 5, starts drive plate 3 and starts working.
As mentioned above, embodiments of the invention are explained, obviously, as long as do not depart from fact inventive point of the present invention and effect, will be readily apparent to persons skilled in the art distortion, is also all included within protection scope of the present invention.
