the system of the example of a kind of proving installation that Fig. 2 provides for the utility model embodiment forms structural drawing, with reference to Fig. 2, in this system, described automobile electronic module is tested controller, described instruction generation unit is the industrial computer that is connected with auxiliary input device and display device, described the second normal signal generation unit is programmable power supply, accessory power supply, the bus transceiver, bus interferometer and integrated circuit board, described the second fault indication signal generation unit is integrated in integrated circuit board, described the second test signal generation unit is that fault is injected box, described receiver module, described analysis module and described update module are integrated in the bus transceiver, described interface is that tested controller and fault are injected the interface between box.
Wherein, industrial computer, bus transceiver, bus interferometer, programmable power supply, integrated circuit board, fault are injected box and are connected controller by the connection of lan controller bus.Accessory power supply and programmable power supply are connected to integrated circuit board by pressure-wire respectively.Proving installation in this example and line can be integrated in same test cabinet.
Described the second fault indication signal sends to fault to inject box by integrated circuit board.If fault injection box not slave plate clamping is received described the second fault indication signal, fault injection box shows as channel status, is about to described the second normal signal and sends to tested controller as described test signal; Described the second fault indication signal is received in clamping if fault is injected the box slave plate, state corresponding to described the second fault indication signal is changed in the circuit connection of inside, thereby tested controller is deliberately received in the circuit of certain fault.The failure mode that fault injection box can be simulated mainly contains input/output port to power supply short circuit, input/output port shorted to earth and input/output port open circuit.
Preserved the test configurations information of a plurality of test items in industrial computer.After being activated by industrial computer, the bus transceiver can be got by industrial computer the test configurations information of these a plurality of test items.Each bus transceiver will call the test that industrial computer carries out next test item after obtaining actual test result according to test signal and response message analysis.When industrial computer is tested each test item, can be by lan controller bus control bus transceiver, bus interferometer and/or the programmable power supply change input to integrated circuit board, sometimes also can Control card the integrated circuit board internal circuit be connected and make a change, integrated circuit board is input to fault injects the signal of box and be transmitted to tested controller or integrated circuit board is input to fault and inject and after the signal of box is made fault handling, fault-signal is sent to tested controller thereby make fault inject box.
The bus transceiver can be after the test item test of all-network test be completed the unified test report that generates all these test items, and after the test item test of all diagnostic tests is completed the unified test report that generates all these test items; Perhaps, also can after completing, all test items unify to generate the test report of all these test items.
The workflow of this system can be as shown in Figure 3.The working-flow figure of the example of a kind of proving installation that Fig. 3 provides for the utility model embodiment.After bringing into operation, industrial computer carries out the initialization of this system: control programmable power supply and accessory power supply and power on, activate the bus transceiver, control fault injection box by integrated circuit board and power on to tested controller.After the bus transceiver is activated, judge whether to carry out network test according to test configurations, if so, enter network test branch; Otherwise, enter diagnostic test branch.
For network test branch, the bus transceiver judges that whether current test item needs bus to disturb, and obtains one first judged result.First when the determination result is NO, the bus transceiver need to judge whether the transform controller power supply mode, obtains one second judged result when this.Second when the determination result is NO, the bus transceiver sends corresponding bus to the lan controller bus and sends message, receives the response message from tested controller, and obtains actual test result when this; When this second judgment result is that when being, bus transceiver indication industrial computer is controlled miscellaneous equipment with the power supply mode of the tested controller of conversion, after the bus transceiver detects the power supply mode conversion and completes, send corresponding bus to the lan controller bus and send message, reception is from the response message of tested controller, and obtains actual test result.When this first judgment result is that when being, the bus transceiver starts the bus jamming equipment, and the control bus jamming equipment sends corresponding bus undesired signal to the lan controller bus, then the bus transceiver sends corresponding bus to the lan controller bus and sends message, reception is from the response message of tested controller, and obtains actual test result.
The bus transceiver judges whether the test of the test item of all-network test has all been completed, and if so, actual test result and the expected test result in test configurations information according to the test item of each network test generates test report; Otherwise the test item of the network test that the next one is not carried out is controlled the test of new current test item as current test item.
After the test report of the test item of bus transceiver generation all-network test, judge whether to have completed diagnosis test sequence according to test configurations, if so, finish all content measurements; Otherwise, enter diagnostic test branch.
For diagnostic test branch, for each current test item, bus transceiver indication industrial computer is controlled miscellaneous equipment take the power supply mode of the tested controller of conversion and then as the corresponding fault of tested controller simulation.After the bus transceiver detects the power supply mode conversion and completes, send corresponding bus to the lan controller bus and send message, receive the response message from tested controller, and obtain actual test result.
If the test item of the diagnostic test of testing is still arranged, the test item of bus transceiver diagnostic test that the next one is tested as new current test item, is controlled the test of new current test item.When the test item of all diagnostic tests is all tested when completing, the bus transceiver generates test report according to actual test result and the expected test result in test configurations information of the test item of each diagnostic test.
The bus transceiver judges whether to have completed the network test sequence according to test configurations after generating the test report of test item of all diagnostic tests, if so, finishes all content measurements; Otherwise, enter network test branch.
The above is only the embodiment of the utility model embodiment; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model embodiment principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the utility model embodiment.
