The invention discloses a test method of an engine controller software diagnosis module on the basis of the USB-CAN (Universal Serial Bus-Controller Area Network) network communication equipment and the automobile diagnosis instruction set tool of the NI Company (National Instruments). The method comprises the following steps: designing an Excel-based diagnosis software test template file; according to the test template, compiling a diagnosis software test case which conforms to a test template format; obtaining the test template file input by a user, analyzing the test template appointed by the user, and generating a data structure used for describing a test template test case and controlling a test process; controlling a test flow; analyzing a simulation working condition; generating a diagnosis communication data frame; receiving and transmitting the communication data frame; judging a test result; realizing interaction with the working condition environment of an engine controller; and outputting a test report and a log file. The invention also discloses a test system of the engine controller software diagnosis module on the basis of the USB-CAN network communication equipment and the automobile diagnosis instruction set tool of the NI Company. The test method can improve the test efficiency and the test quality of the test work of the engine controller software diagnosis module.

The invention relates to a spot measurement mechanism for an LED light sorting machine and the LED light sorting machine with the spot measurement mechanism, wherein the spot measurement mechanism is good in probe contact, long in service life, accurate in spot measurement testing and not prone to being stuck.According to the spot measurement mechanism for the LED light sorting machine, probes and an installation structure in the prior art are improved, each probe is provided with an air flow channel, the surface of a probe tip of each probe is provided with vent holes communicated with the corresponding air flow channel, air flow is blown off from the vent holes formed in the surfaces of the probe tips, residual packaging glue remaining on the testing probe tips can be cleaned away, and long-time good contact between the probe tips of the probes and electrode pins of LED lamp beads can be maintained; sleeves are additionally arranged, the sleeves are arranged on the probes in a sleeving mode and fixed in through holes, the probes can move relative to the corresponding sleeves, gaps between a support plate and the probes are filled with the sleeves, the residual packaging glue is prevented from entering the gaps, and contact point deviations caused by transverse displacement of the probes are avoided.The invention further provides the LED light sorting machine with the spot measurement mechanism.

The invention discloses an electrical test assembly, which comprises a frame, at least one test station is arranged on the frame, the test station has a supporting part for placing a tooling board with products, and the test station is movable A test plug assembly is provided, the test plug assembly is located above the supporting part, and the test station is provided with a linear driver for driving the test plug assembly to move up and down relative to the supporting part, and the test plug assembly and the test socket on the tooling board There is a deviation correcting structure for adjusting the relative position of the two. The electrical test assembly with the above structure uses a linear driver to drive the test plug assembly up and down to move closer to or away from the test socket on the tooling board, and at the same time uses the correction structure to adjust the relative position between the test plug assembly and the test socket, so as to realize the function of correction and avoid The test plug assembly and the test socket cannot be accurately docked, thereby avoiding test failure and ensuring the working efficiency of the test process.
