The invention belongs to the field of material ultra-high temperature mechanical property testing, relates to a test instrument for material mechanical properties at ultra-high temperature, in particular to an instrument for measuring the mechanical performances (for example, indentation characteristics, hardness and the like) of an object to be tested under ultra-high temperature conditions, anda high-temperature furnace with a special structure used in the instrument. The high-temperature furnace comprises a furnace body, a furnace bottom and a furnace cover, wherein the furnace body is connected with the furnace cover in a dynamic sealing manner, the furnace body and the furnace bottom are welded and in machine-made leveling to be formed integrally. The test instrument for the materialmechanical properties at the ultra-high temperature comprises the high-temperature furnace, and further comprises a sample rotating component, a data acquiring-processing component, an automatic control component and a vacuum pumping component and / or a protective gas filling component. The test instrument for the material mechanical properties at the ultra-high temperature, disclosed by the invention, not only maintains vacuum or protective atmosphere in the high-temperature furnace to solve the problems of inconvenient operation and the like caused by that the hardness tester or indenter inthe prior art is integrally kept in the vacuum or protective atmosphere.

The invention discloses a system for automatically diagnosing a fault of a circuit board. The system comprises a testing probe, a signal excitation device, a signal testing device, a central control machine and a robot movement mechanism, wherein the central control machine controls the signal excitation device; the signal excitation device is connected with a signal excitation end of a circuit board; the testing probe acquires data of a tested point of the circuit board to be transmitted to the signal testing device; the signal testing device processes the data and transmits the data to the central control machine; the central control machine controls the robot movement mechanism; the robot movement mechanism is used for controlling the testing probe to move; and the testing probe is used for testing the fault of the circuit board. The robot movement mechanism is controlled to drive the testing probe to move to a target testing point by the central control machine, so that fault diagnosis of the circuit board is fully automatically tested, manual operation is replaced by the robot movement mechanism, and manual labor is saved; and moreover, the fault of the circuit board can be accurately tested, and the system is convenient to use.

The invention discloses a power device IO plug-in automatic test method suitable for pipeline production. A database, a computer, a tester, an auxiliary device and the like are provided; the databaseis used for barcode identification and test data storage; the computer is used for test management and fault positioning realization; the tester comprises a main control board, a backplane, a terminalconversion matrix, a backplane interface conversion module, a pin bed and the like; the terminal conversion matrix achieves automatic test wiring by switching a working bus; in the case of output test, main / standby double-input voltage sampling is used, and comparison error proofing is carried out; interface or level conversion is carried out through the backplane interface conversion module so as to meet requirements of a to-be-tested plug-in; and IO test is regularized to two steps of setting output and comparison input, the universality and the extensibility of an IO plug-in test logic areensured, and flexible pipeline production requirements can be well met.
