If finished predetermined testing time, then entered step 511: return success information.
Otherwise, enter step 512: judge and whether carry out switching for twice interval delay time SwpDelay continuously greater than 60000.
If SwpDelay greater than 60000, then enters step 513: time-delay SwpDelay switches test next time after the time, up to finishing predetermined testing time.
Otherwise enter step 514: continue to call the operating state that the QueryBoard function obtains current standby plate, up to inquiring the standby plate mode of operation for normal, test is switched in beginning next time behind the SwpTTime that then delays time, up to finishing predetermined testing time.
In the TCL script, trigger and switch, can regularly initiate switching operation, also can allow script control automatically, be that script judges that the state of current active and standby plate is all normal, then initiate switching operation, switch active and standby plate such as back all normal again after, then initiate the next round switching operation automatically.
In the reality test, can use board switchover that equipment under test provides, reset, order such as electricity realizes switching operation down, wherein switching switching of order control belongs to initiatively and switches, reset, descend electric main board can cause main board unusual, then standby plate can be upgraded to main board automatically, belongs to passive and switches.For the state of the primary and backup veneer of equipment under test, also can realize by the board querying order that control of product maintenance console provides.Make simple and fast in this way, usually, equipment all provides these basic inquiry and operational orders in the product maintenance control desk.Calculating for switching time, the order Time that uses TCL to carry realizes, when initiating to switch, open a timer, can obtain switching the required time Deng inquiring once to switch when successfully finishing according to timer, number of times and the time of switching each time, result etc. are switched in statistics output in the script simultaneously, for all outputs in the test, use the print command puts of TCL standard all to export, test result is come into plain view.
With reference to Fig. 6, Fig. 6 utilizes order to finish the flow chart of switching in the inventive method, may further comprise the steps:
Step 601: utilize the Time order of TCL to open a timer, pick up counting.
Step 602: transmitting order to lower levels is to the designated port of equipment under test, and catches the return value of this order in the TCL script.This return value can comprise multiple information, such as, the state information of corresponding veneer, operation information etc.Usually equipment is all supported MML (man-machine language) interface, and real-time command is provided.
Step 603: the sign that utilizes the string matching commands match among the TCL to run succeeded to return value.
If coupling is unsuccessful, illustrate and switch failure, at this moment, enter step 604: utilize the puts order of TCL to switch failure information to the test window transmission, and return value " 0 ", show that the switchover mode of failure is switched for order.
If the match is successful, illustrate and switch successfully, at this moment, enter step 605: use QueryState to obtain the activestandby state of current single board.
Enter step 606: whether standby plate became the main state of using before inquiry was switched.
If the standby plate inquiry is main usefulness before switching, then enter step 607: stop the timer timing, and obtain timing time, be i.e. the switching time of veneer.
Step 608: the board switchover time of obtaining is sent to test window by the puts order.
If the standby plate inquiry is then returned step 605 for standby before switching: continue to use QueryState to obtain the activestandby state of current single board.
Like this, just finished once complete order reversed process.
The implementation procedure of switchover mode of resetting is identical with the mentioned order reversed process, and just when switching failure after, when failure information is switched in the test window transmission, return value " 1 " shows that the switchover mode of failure is switched for resetting.
The implementation procedure and the mentioned order reversed process of electric switchover mode are also similar down, are after switching failure, when failure information is switched in the test window transmission, and return value " 1 ", the switchover mode that shows failure is that electricity is switched down; And, switch at every turn finish after, need the designated port of transmitting order to lower levels to equipment under test, give down that the veneer of electricity re-powers, switch test with the following electricity of preparing next time.
