Description
Technical field
The present invention relates to locomotive test technical field more particularly to a kind of locomotive self-tests based on the interaction of driver's display screen
Method and locomotive test method.
Background technique
Electric locomotive is used since design to investment is formal, is needed by careful and stringent test process.From component
Joint test before, the shop test to after being completed, the type approval test after factory and the last running assessment of grade
Test, the test in each stage are all carried out in strict accordance with test program, and the purpose is to guarantee that locomotive enters the main track operation phase
Stability and safety.
The traditional content of the test of electric locomotive includes rising pantograph, drop pantograph test；Co-host break road device, sub-main break road device
Test；Traction, electricity system test；The functions such as nobody vigilant test.In the prior art, above-mentioned function be all 25kV High-Voltage Network under into
Row test.Specifically, as shown in Figure 1, when Keep Clear-High Voltage the test operation such as pantograph, main disconnected, when experimental condition meets, then directly
It connects to be sent instructions by central control unit (CCU) and carries out actual experimental.When a test is begun, by being issued a command under central control unit
Correlation unit, such as traction control unit, brak control unit, remote input output unit, auxiliary system unit, these units
After receiving instruction, feedback action state is to central control unit, after central control unit acquires all relevant location modes, warp
Internal logic calculating is crossed, is obtained a result, is last transmitted to display screen and shows.
However, technical staff has found that there are still following disadvantages for the prior art:
1) when operation correlation test under try net, once there is mistake or emergency case, Bu Nengji in the interaction of each equipment
When drop pantograph, sub-main break, commissioning staff can face electric shock etc. dangerous situations.
2) when test off the net, all network variables are all to pick up from real equipment operational data, the work shape of these equipment
State is only current working status, is unable to test equipment damage or malfunction.That is, the prior art is carrying out
When test off the net, all situations cannot be sufficiently tested.Once not sufficiently test, encounters fault condition, microcomputer possibly can not be made
Corresponding safeguard measure.
3) test period off the net is urgent, and when test encounters problems, test condition at that time does not often allow to reappear, and causes to adjust
Examination personnel are not easy the basic reason to search problem.
4) off the net to test the cooperation for needing various aspects unit, high-tension line ensures department's maintenance department, design department, maintenance
Department etc. requires cooperation, and the time of debugging is long, at high cost.
5) when locomotive carries out above-mentioned test, once test central control unit (CCU) interacts with each equipment and mistake occurs
Or emergency case, it is impossible to drop pantograph, sub-main break in time, the loss that can not be retrieved may be caused to locomotive.
Therefore, locomotive sufficiently tests pantograph, main disconnected and other equipment control system before 25kV test off the net
Internal logic guarantees the safety of the formal test off the net of locomotive, becomes a urgent problem to be solved.

Realize lifting/lowering bow, point/co-host break road device, traction/electricity system, nobody the functions such as be vigilant, other are consistent with normal drive mode.
Embodiment
As shown in figure 4, the locomotive self-test method based on the interaction of driver's display screen disclosed in the present embodiment, into survey certainly
After trying interface, interface prompt goes out to enter the condition that simulation test needs to meet, condition as shown in Figure 3: " locomotive is in static state
Under ", " pantograph be in drop arciform state ", " main circuit breaker is in an off state ", the conditions such as " blue key is in truncation position ", these
After condition passes comprehensive descision by central control unit, result is sent to display screen.When a certain condition meets, implied condition language
Filling green in the small box on sentence the right, on the contrary filling is red.
Display screen judges whether to meet all test conditions, as shown in figure 4, interface is most lower if full terms meet
" starting to test " key of side is enabled, as long as a condition on the contrary is unsatisfactory for, key is not enabled.
Key is not enabled then to exit test.The key that key is enabled then to be pressed by tester " test ", Xiang Zhongyang
Control unit transmission starts test instruction.
Central control unit is after being connected to test sign on, in the case where not rising bow, carries out pantograph logic, master is broken
The calculating of logic, traction/electricity logic processed, nobody vigilant logic.Such as when simulating rising bow test, central control unit is sentenced first
To break each rising bow condition, if condition all meets, simulates and issue rising bow instruction, simulation pantograph is in rising bow state, while
Network pressure value is exported in communication data stream, simulates the network pressure of 25kV, display screen is truncated to network pressure and other parameters in a stream,
It shows on a display screen.
During simulation test, display screen carries out information alert to commissioning staff according to the instruction of central control unit,
" asking rising bow " in such as Fig. 3 similar prompt statement, this prompt change according to test case, until test terminates.
After the completion of the test of all corners, the key of " stopping testing " is pressed by commissioning staff, display screen informs center control
Unit testing processed terminates, and display screen jumps out this interface automatically, and self-test is completed.
Carry out actual experimental.
