In the present embodiment, using the upper computer software of CAN analyzer 4 by received CAN communication signal and setting signal phase
Compare, it is normal with the communication function of this radar L to be detected being connected to all the way if identical, if it is different, then connecting all the way with this
The communication function of logical radar L to be detected is abnormal.
It carries out that the waveform of CAN signal can be will acquire when communication function test and the standard CAN signal waveform of setting is opposed
Than.Such as the CAN frame waveform based on message is obtained, judge whether communication is normal by CAN frame waveform.
It can also be compared by the message that will acquire with standard message, such as parse received message, obtain message
The details such as frame type, data length, frame ID, frame data, by above- mentioned information judge received message whether mistake, in turn
Judge whether the communication function of radar L to be detected is normal.
Host computer 2 judges whether be located at setting from current collector 3 or the received current value of Multipath current collector 31
Current value range in, if radar L electric property to be detected is normal, if it was not then radar L electrical resistance to be detected
It can be abnormal.In the present embodiment, host computer 2 exports the current value on every road within each period, is used to form test record report
Table.According to the difference of radar L-type number to be detected during actual test, the current value range of setting can accordingly be adjusted
It is whole.
In the present embodiment, relay grading control system is formed using the first multicircuit relay 6 and the second multicircuit relay 7
