Testing auxiliary machine case includes FPGA accessory plate, CPU accessory plate and board card slot, and board card slot can be used for the company of fixationConnecing tested board, tested board is inserted directly into subtest cabinet card slot when test, and card slot is connect with auxiliary cabinet inside,Facilitate and carries out subsequent dependence test.FPGA accessory plate and CPU accessory plate are used to send tested board order and receive boardReturn information.
Tester extends IO plug-in unit and exchanges data, direct read/write expansion bus using expansion bus.Tested board and FPGAOrder data Fabric Interface is used between accessory plate, order and data format is the same.
The test macro board can be carried out opening into, output, DC/AC AD, optical port, power port, Ethernet, photoelectricity BCode, light channel, liquid crystal, keyboard, NOR FLASH, NAND FLASH, RTC real-time clock, thermometric, 24V clock synchronization are opened total into, IOThe boards hardware performance test item such as line, expansion bus, SD mmc card, IIC expansion bus.
The basic test thinking of the test macro is: in test, industrial personal computer sends test instruction, tester to testerTest is instructed and carries out dissection process, according to the test pattern that test item judgement uses, tester is by corresponding test patternIt is transferred to subtest cabinet, to test tested board.
The specific embodiment of test process is given below.
When testing tested board, industrial personal computer carries out user login validation first, and editor generates test configurations textPart after tested board type matching, sends test configurations order to tester.
Host computer issues test command message, and tester carries out dissection process to the message received, wraps in command messageTitle containing test item, test method, test pattern, test waiting time, test send message, test sending port, testThe contents such as number.
For the hardware performance of relay protection board, need content to be tested more, single testing process is unable to satisfyAll hardware testings.Tester is divided into following two test mode according to test item, is active test pattern and oneself respectivelyDynamic test pattern, the corresponding test item of active test pattern open into, output, B code etc. is tested, Passive Test mode is correspondingTest item has the test such as optical port, power port.Active test pattern specific implementation means are as follows: tester sends corresponding to tested boardTest command, test board is accordingly tested according to test command, and tester will be sent in test result；Passive TestMode specific implementation means are as follows: tester sends corresponding test command to tested board, after test board receives the orderThe test packet that defines actively is sent to tester, and tester is received to send back to tested board after test packet and be reported on completion of a taskIt enables, tested board is tested after receiving commands in return, and tester then will be sent in test result.
Under active test pattern, test instruction message format that industrial personal computer is sent to tester is according to requiring to be divided into twoKind, it is a kind of for without test data data message, another kind tests data data message to have.Without test data data message lengthIt is fixed, different data segments has been carried out to show difference for different test-types in data framing；There is data data message to visit numberIt is not fixed according to message length, includes not only test-types in message, joined test data sum number also according to different test-typesAccording to type.When belonging to has data type of message, tester handles message, specifically takes out data and carries out weightStructure, and required to be sent to the accessory plate tested in auxiliary cabinet, test by serial ports, cable or Ethernet according to dependence testTest command in instruction is individually sent to test auxiliary cabinet by Ethernet；When belonging to no data type of message, testTest command is directly sent to test auxiliary cabinet by Ethernet by instrument.In addition, if the message that industrial personal computer is sent instructs notBelong within the scope for the treatment of mechanism, then tester sends alarm signal to industrial personal computer.
For opening test, driving is opened while tester forwards " enter and open into test pattern " order to tested boardPlug-in unit enters " outputing dedicated tunnel " and orders out；The state into front terminal is opened in tested board self-test, is sent and " is opened into shape on testerState response " message；Tester " will open into state response " message and be transmitted to host computer, host computer carry out test result judgement toComplete the test that Ben Lukai enters channel.
By taking optical port testing as an example, directly this order is sent to after tester receives " optical port testing mode " order testedIn board, tested board actively sends the optical port testing message defined to tester optical port after receiving optical port testing order, surveysExamination instrument optical port sends commands in return immediately after the message for receiving specific frame head, after the optical port of tested board receives this commands in returnIt is tested, only by the result by sending on tester to host computer.
Under any circumstance the communication test order of tester be interacted by subtest cabinet with tested board, butWhen Passive Test mode, the test packet defined sent in tested board active can not also be by subtest cabinet, directlyTest, such as serial ports test, fiber optic communication test, ethernet test etc. are interacted with tester relevant interface.
