Accompanying drawing explanation
Fig. 1 is protective relaying device veneer automatic test approach schematic flow sheet of the present invention;
Fig. 2 is method of testing hardware connection layout of the present invention.
Embodiment
Below in conjunction with Figure of description, technical scheme of the present invention is described in further detail.
Accompanying drawing 1 is the process flow diagram of the inventive method, and veneer to be measured is connected by backboard CAN bus, also can pass through Ethernet switch networking, and server (or claiming test background) sends test procedure packet on the net in LAN (Local Area Network) or CAN.
In veneer to be measured, increase a Hook Function, this function receives after certain data packet message verification correctly, can carry out specific action.
When server (or claiming test background) has the request of the test file of transmission, veneer to be measured extracts test procedure executable code from message packets, deposits and specifies in RAM district.
Meeting after test procedure transmits successfully, veneer to be measured sends and transmits success message and cut out and transmit test file request, described veneer to be measured carries out verification to autotest program, verification by after start to judge whether testing ram; If autotest program verification unsuccessfully can send verification failed message, enter the wrong function of processing and return to again the state after initialization.
While needing testing ram, veneer to be measured can be transferred to test procedure in flash and move, after transfer, also can carry out verification to it, verification is by just starting testing ram, tested again test procedure to be moved back into and specified RAM district, enter the initial phase of testing service responding process, when not needing RAM to test, test procedure directly enters this stage.If verification failure in test procedure CongRAM district transfers to flash process, sends flash test crash message (test procedure shifts unsuccessfully can be considered as flash existing problems), enter the wrong function of processing and return to the state after initialization afterwards.
After the initialization of testing service responding process, first can judge whether test command changes: if changed, start to transmit test configurations information, whether transmission completes verification and transmits successful, when transmitting successfully, start to carry out individual event test (for the hardware cell on veneer or module, test separately, as flash, AD, power supply etc.), individual event test finishes that rear to judge whether all test commands respond complete, just as the complete test procedure that exits of all test commands responses, report is completed; If test command does not change or test configurations information transmits unsuccessfully, send that to judge whether all test commands respond after the unchanged message of test configurations information complete, as complete in do not responded, just return, judge whether test command changes and rejudge.
Testing progress and test result are sent in real time host computer by the designated port on veneer to be measured and show, after test finishes, veneer power down also powers on again, and during application program self check RAM, cleaning can be carried out RAM district packet, and test procedure is deleted automatically.
In the automatic testing scheme of design, each hardware composition part for veneer, designs independently autotest program, and is compiled into executable code, forms packet.This packet is exactly that packet that downloads to the operation in veneer of saying above.Packet comprises method of testing, flow process, criterion and the stipulations for certain hardware composition part.These packet independent numberings.For certain veneer, select the packet of adaptation, form a test template.After single board communication, packet is downloaded, is carried out one by one, and execution result (test result) is reported, and completes test job.
Data when this veneer power down Hou， RAM district will not exist, even if exist, can not be performed yet.Because after powering on, according to plug-in unit setting, what move is application program.After application program self check RAM, this region can be cleared up again, thoroughly solved and in operational process, be strayed into test link.
For same class veneer, a lot of peripheral hardwares are the same, can not overlapping development test use " packet ".These packets can now generate in use, also can generate in advance rear preservation.Now the benefit of generation is, can according to stipulations text, automatically generate up-to-date code at any time, and the benefit generating is in advance to save time.Also can both be combined according to actual conditions, to improve testing efficiency.
As shown in Figure 2, two veneers to be measured are connected by backboard CAN bus the hardware connection diagram of method of testing, and a plurality of serial ports can be connected in combination in any mode.Can one of them serial ports be connected with host computer for veneer to be measured as required, manual mode is selected test event, two veneers to be measured and host computer can also be received on switch simultaneously, host computer visits tested single board by Ethernet, selects test event.
When test communication function, during as testing CAN bus communication, can transmit detecting information and order by serial ports or Ethernet, verify that whether communication is normal, can be by CAN bus or serial ports (or Ethernet) checking while in like manner testing Ethernet (or serial ports) communication, that is to say that three networks can verify mutually, guarantee the reliability of communication.In addition, when serial ports is tested, perhaps can there is a plurality of serial ports or Ethernet interface in board under test, at this moment do not need to fix the port corresponding relation of two plates, program can be accomplished automatically identification mutually, determine that the other side is which port with which port of oneself communicates, and improves dirigibility and the adaptivity of method of testing.
