Description
Technical field
The utility model belongs to technical field of electromagnetic compatibility measurement, is surveyed more particularly, to a kind of electromagnetic compatibility free field anti-interference
Try network communication monitoring system.
Background technology
With the continuous promotion of automotive engineering in recent years, the electronic device used in the car is more and more.Vehicle-mounted control
Device processed carries out information to vehicle mounted electric device and transmits and control, and vehicle mounted electrical apparatus is made to work normally.Gasify in industrial electro more powerful
Today, residing electromagnetic environment also becomes increasingly complex in car running process, is needed during automotive development based on this point
Carry out electromagnetic compatibility anti-interference test.It is monitored by the network communication to automobile, electrical part signal during experiment, so as to
Observation, analysis vehicle operating status, while the quick positioning confirmation of problem of implementation electrical part.
Automotive EMC free field anti-interference test is divided into two steps of test implementation and test result analysis.
The existing anti-interference test monitoring method of electromagnetic compatibility is：Vehicle work is carried out by image documentation equipment during the test
Condition appearance monitors.This monitoring changes and can not judge to the operating mode that some are subtle in anti-interference test process, and to not
The case where displaying but not meeting test request can not be judged.Such as the work of automobile blower motor, it is tested in anti-interference
In the process if blower motor moment is stopped 0.1 second, the picture sent by image documentation equipment can not be judged；Again
For example New-energy electric vehicle carries out in anti-interference test process, if DC/DC is stopped, this abnormal phenomenon can not pass through shadow
As picture is judged.
After anti-interference is tested, vehicle network communication equipment, investigation are utilized for the unusual service condition occurred in test process
Vehicle network communication positions the electrical part that goes wrong.But this monitoring has prodigious hysteresis quality, because going out in anti-interference test process
Existing abnormal phenomenon can may automatically restore normal after anti-interference is tested.Some can even go out in certain specific frequency ranges
It is now abnormal, just automatically restore to normal condition during testing other frequency ranges.Therefore after anti-interference is tested again into
Row network communication monitors, and may miss or can not find problematic electrical part.Such as instrument face plate after anti-interference test
On the alarm lamp that does not disappear, corresponding problem part can be found by monitoring vehicle network, but if anti-interference is tested
After some or all of disappearance of alarm lamp on instrument face plate, will be unable to search by network monitoring in this case
Problem part.
Existing automotive EMC free field anti-interference test is not carried out at the same time with vehicle network communication monitoring, and there are following
Some shortcomings：
(1) anti-interference test is not carried out at the same time with network monitoring, may be missed certain abnormal phenomenon in anti-interference test, be influenced
Final anti-interference test grade judgement；
(2) there are hysteresis quality, when anti-interference carries out investigation positioning after testing to the abnormal phenomenon occurred in test process
The problematic electrical part in part may be missed.
(3) increase time and economic cost, need to carry out network communication monitoring and problem electrical part again after test
Investigation positioning.For restoring failure automatically, need to implement to test again.

Photoelectric conversion module, for carrying out electromagnetic compatibility free field anti-interference test；
The network communication monitoring system includes the first photoelectric conversion module and network communication monitoring device, whole for monitoring
Vehicle vehicle bus network communicates, and the network communication monitoring device is separately connected the second photoelectric conversion module and computer, by the
The vehicle network signal that the transmission of two photoelectric conversion modules comes is sent in computer.
Further, the network diagnosis interface of one end connection tested vehicle of first photoelectric conversion module, the other end
Network signal is transmitted out the laboratory of carry out anti-interference test by connection optical fiber, and connects the second photoelectric conversion module.
Further, it is equipped in the computer and the matched software of network monitoring device.
Compared with the existing technology, a kind of electromagnetic compatibility free field anti-interference testing network communication monitoring described in the utility model
System has the advantage that：
