It should be noted that, through the research of the inventor, it is found that, in the whole vehicle, the load power supply of the whole vehicle supplies power to the electronic instrument, when the battery of the load power supply is in a power shortage, the instrument can be lightened, but when the battery is in the power shortage, when the battery is lightened or ignited, the voltage of the battery is pulled down to generate interference pulses, and the problem of adapting the instrument to the whole vehicle is caused. Such conditions are often the case where the vehicle has not started for a long time and then suddenly started, or where there is a break in the power supply of the whole vehicle.
The electronic instrument has complex functions, and the test is mainly manual test and whole vehicle test. The manual test is to use a great deal of manpower to perform single test on one signal, and the operation is complex and complicated. The whole vehicle test needs to be delivered to a host factory frequently, and each time the test project and the working condition are single, the development efficiency is low. In the existing test fixture of the electronic instrument, the input signal of the whole vehicle to the electronic instrument can be simulated only through the test fixture so as to test whether the electronic instrument can output corresponding information or not, and then whether the function of the electronic instrument is normal or not is detected. The working condition of the electronic instrument in the condition of power shortage of the whole vehicle battery can not be simulated through the existing test tool, so that the electronic instrument needs to be tested to a host factory for many times in the development process. In the vehicle electronic instrument testing tool provided by the embodiment of the utility model, the second power module 60 is used for simulating the load power supply of the whole vehicle, so as to supply power to the electronic instrument during testing, and then the signal conditioning module 30 can send out simulation interference signals according to the signals sent by the main control module 20 when the battery in the second power module 60 is in power shortage, wherein the simulation interference signals comprise but not limited to interference signals such as lighting, ignition, horn, contact ignition and the like, and further simulate the testing of the electronic instrument under the working condition of battery power shortage.

The first power module 50 and the second power module 60 are used for supplying power to the main control module 20 and the signal conditioning module 30 respectively, and the main control module 20 and the signal conditioning module 30 are arranged at intervals, so that the power supply is managed separately in the power supply part, that is, the signal conditioning module 30 only receives the power supply of the second power module 60, the electric interference caused by the first power module 50 can be avoided, that is, the power supply is independently performed through different power modules, the second power module 60 can better simulate the whole vehicle environment, and the non-whole vehicle interference signals caused by the main control module 20 are reduced.
In this embodiment, the vehicle electronic test fixture further includes a man-machine interaction module 10, and the man-machine interaction module 10 is electrically connected with the main control module 20.

For example, the instruction may be sent to the main control module 20 through a key, where the instruction includes but is not limited to instructions such as lighting, pressing a horn, and striking a fire, and the main control module 20 then carries out transportation according to the instruction, outputs an initial interference signal, and outputs and obtains a simulated interference signal through the signal conditioning module 30, where the simulated interference signal corresponds to the instruction, that is, simulates the interference signal such as lighting, pressing a horn, striking a fire, and the like. For example, when the second power module 60 is deficient, a firing command is issued according to the man-machine interaction module 10. The signal conditioning module 30 can simulate the ignition signal sent by the whole vehicle, the simulated ignition signal is also a simulated interference signal, so that the interference to the electronic instrument is realized, if the electronic instrument has a fault caused by the simulated interference signal, a user can develop the electronic instrument in an improved manner according to the fault, and the electronic instrument meets the use requirement.
It should be noted that, in some other embodiments, the man-machine interaction module 10 is not limited to the above structure, but may be other special structures through which the user can send instructions to the main control module 20.

And the shielding module may also be designed with other structures to realize that the main control module 20 is not interfered by signals. It is not particularly limited herein.

And the signal conditioning module 30 is electrically isolated and physically isolated from the output management module 40 and the second power module 60, so that interference influence of the second power module 60, the output management module 40 and the environment is reduced, and accuracy of signals is ensured.
Further, in this embodiment, the vehicle electronic instrument testing tool further includes an output management module 40, where the output management module 40 includes an input end and an output end, the input end is electrically connected with the signal conditioning module 30, and the output end is electrically connected with the electronic instrument and is used for outputting the analog interference signal input by the signal conditioning module 30 to the electronic instrument. I.e. to send signals such as simulated ignition, lighting, horn, etc. to the electronic instrument. And then simulate the environment of the whole vehicle.
Further, the number of output ends in the embodiment is more than two. It can be understood that the test of a plurality of electronic instruments can be simultaneously carried out through the connection of more than two output ends and more than two electronic instruments in a one-to-one correspondence manner, so that the development efficiency of the electronic instruments is improved.
The same analog interference signal may be output to different output terminals, or different analog interference signals may be output, for example, to two output terminals, one of which outputs an analog ignition signal and the other of which outputs an analog ignition signal, or other signals different from the ignition signal, for example, signals such as lighting or horn.
Of course, in some other embodiments, the number of output ends may be one, and the number of output ends is not specifically limited herein.
