Abstract
The invention discloses an electric locomotive control unit function test bed comprising a frame and a signal control processing portion. The frame is used for holding five types of electric locomotive control units. The five types of control units can be inserted onto corresponding positions for independent function tests but cannot be inserted into the frame in the same time. The signal control processing portion comprises a power supply device, an industrial personal computer, a PXI case, a communication case, a display, related communication software and the like. When one type of control unit is inserted for function test, the power supply device powers the industrial personal computer, the PXI case, the communication case and the control unit under test, the industrial personal computer controls the PXI case and the control unit under test to be subjected to signal generation, reading and testing through the communication software, and the communication case assists in testing network communication of the control unit under test. The electric locomotive control unit function test bed is simple and reasonable in structure and has lower cost than domestic and abroad imported like products. Through the application of the bed, the five types of control units can be tested automatically with no need of manually testing any signal.
Description
Technical field the present invention relates to locomotive control experiment detection device, particularly the function test pick-up unit of electric locomotive control module.
The traction control of background technology electric locomotive and network control unit are as the critical component of electric locomotive, and its function test is an important step in new product development, production run.By function test, can verify the mentality of designing of product, find design defect and the production technology problem of product, be next step entrucking establish a firm foundation.At present, testing table that can five kinds of control modules of integration testing electric locomotive is all from external import, not only expensive, safeguards that aspect also exists very large problem.
Summary of the invention
For solving above-mentioned the problems of the prior art, the electric locomotive control module function test bed that the object of the present invention is to provide that a kind of cost is lower, easy maintenance and five kinds of control modules (Main Processor Unit, traction control unit, Auxiliary Control Element, remote input output control unit, driver display unit) of can be a kind of electric locomotive of vehicle provides functional test.
Technical scheme of the present invention is as follows: electric locomotive control module function test bed of the present invention consists of frame and the signal controlling processing section of placing five kinds of control modules of electric locomotive.
The frame of placing five kinds of control modules of electric locomotive comprises the frame of Main Processor Unit frame, traction control unit rack, Auxiliary Control Element frame, remote input output control unit frame and driver display unit.These five kinds of control modules can insert corresponding position and carry out separately functional test, but can not all insert in frame simultaneously.
Signal controlling processing section comprises electric supply installation, industrial computer, PXI cabinet, communication machine box, display and related communication software etc.When certain control module of insertion carries out functional test, by electric supply installation, to industrial computer, PXI cabinet, communication machine box and tested control module, powered, by industrial computer, by communication software, control PXI cabinet and tested control module carries out signal generation, reads and tests, the network service test of tested control module has been assisted by communication machine box.
Adopt after technique scheme, of the present invention simple and reasonable, cost is lower than external import like product.By testing table of the present invention, can automatically test five kinds of control modules, without the arbitrary signal of manual test.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
The present invention can test five kinds of control modules of electric locomotive automatically, and this sentences test Main Processor Unit is that example is told about embodiment, and the test of other control modules is similar with it.
Main Processor Unit functional test principle schematic as shown in Figure 3.Main Processor Unit is comprised of power panel, digital IO plate, analog input plate, Main Processing Unit, FIPT communication board, FIPV communication board, status lamp display board, motherboard etc.During test, by veneer, test, first testing power supply plate, then survey digital IO plate etc., a piece plank is tested.
Hardware implementation mode: electric locomotive control module function test bed structural representation as shown in Figure 1.During test, Main Processor Unit is inserted to " Main Processor Unit frame " position.This position is the outer container of Main Processor Unit.Outer container is connected by connector with tested Main Processor Unit, and the connector of outer container is connected to PXI cabinet by cable, and PXI cabinet is linked to industrial computer by cable.The FIPT signal of tested Main Processor Unit is to be connected to communication machine box by cable, and FIPV and RS232 signal are connected to industrial computer by cable.
Implement software mode: develop under the TESTSTAND software environment of test procedure Shi NI company, subroutine can be completed by software developments such as C, Lab view, CVI.Tested Main Processor Unit also needs to download testing software and has assisted test.Test process is as follows: 1, test procedure is powered to unit under test by software control electric supply installation, and the DMM in PXI cabinet carrys out other power parameters such as input voltage, electric current and output voltage of testing power supply plate; 2, download testing software: unit under test need to be downloaded testing software to carry out communication with testing table; 3, unit under test and industrial computer communicate; 4, digital IO test: industrial computer, is fed back to PXI cabinet by unit under test and detects to unit under test input 0,1 by test procedure; 5, analog input test: industrial computer is controlled PXI cabinet output analog quantity to unit under test by test procedure, and PXI cabinet detects unit under test again by the result after processing; 6, RS232 test: by RS232 interface, industrial computer and unit under test are received and dispatched test; 7, FIPT and FIPV test: by software and hardware interface, industry control and receive and dispatch test with unit under test.
The physical circuit relating in the present invention is custom circuit, repeats no more here.
