Fig. 2 is the circuit theory diagrams of the embodiment of the invention
Fig. 3 is the aging test program flow diagram of the embodiment of the invention
The present invention will be described in detail below in conjunction with drawings and Examples for embodiment.
As shown in Figure 1, component product of microcomputer network control system of locomotive of the present invention is dynamic aging test bed, comprises temperature test chamber, frock rack, industrial control computer and the multi-way switch data collection and analysis instrument that communicates with by Ethernet.Wherein, temperature test chamber provides required temperature environment for dynamic aging test, and the frock rack places in the temperature test chamber, and measured piece is positioned over the frock rack.Multi-way switch data collection and analysis instrument 3706 receives the control command of industrial control computer, relay switch control module 3740 and DATA REASONING control module 3720 to its grafting are controlled, implement power on/off by the 3740 pairs of measured pieces of relay switch control module, detect the magnitude of voltage of the unit under test of the current value of measured pieces and measured piece by DATA REASONING control module 3720.The circuit diagram of the embodiment of the invention as shown in Figure 2.
Industrial control computer of the present invention is controlled experimentation automatically by operation LABVIEW dynamic aging experimental arrangement, need not manual operations.Its program flow diagram as shown in Figure 3.
Experiment process of the present invention is as follows: during thermal cycle, unit under test is on/off repeatedly.Respectively to the energising of the measured piece of three racks, the current value of test measured piece, when measuring current value during greater than 2 times of the electric current under the steady state (SS), the red warning of program interface pilot lamp newspaper, the present invention will stop the aging test circulation of unit under test.Unit under test to measured piece carries out voltage detecting then, notes measured value, carries out current detecting in 20 seconds after energising, carries out voltage detecting in 120 seconds after the energising, and be 3 minutes half whole conduction time.Outage afterwards, power-off time are that half, one circulation in 2 fens needs 6 minutes altogether.The on/off total degree of power supply is 110 times in 11 hours test duration.Generate a file when finishing, write down start time, input voltage, current value and the magnitude of voltage of the power on/off in this cycle, the value that surpasses rated voltage is given " false " sign in each cycle.Finish to this dynamic aging test.
