To be touching display screen.During detecting system is detected each bonding dots 110, fault verification submodule 133 is also
For real-time statistics fault point quantity, for example, when detecting system just powers on, 110 quantity of failure bonding dots is initialized as 0.With
Detection to each bonding dots 110, fault verification submodule 133 often determine a failure bonding dots, failure bonding are counted
Amount is done plus 1 processing.Assuming that fault verification submodule 133 judges bonding dots 2 and bonding dots 3 there are when failure, fault verification submodule
Block 133 judges that bonding dots 2 are failure bonding dots, and the quantity of failure bonding dots is added 1, and judgement bonding dots 3 are failure bonding dots,
And the quantity of failure bonding dots is added 1 again, transmit it to display module after finally counting the bonding dots quantity (such as 2) that is out of order
180 are shown.I.e. when bonding dots 2 in N number of bonding dots 110 and bonding dots 3 are there are when failure, display module 180 will show event
Hinder bonding dots 2 and 3 corresponding position of failure bonding dots and failure bonding dots quantity 2, and sends out abnormal alarm.
Optionally, display module 180 may include input button, and user can be according to actual conditions to each bonding dots
110 pressure drop threshold value is set.For example, before vehicle release, automobile-used earth system carries out each bonding dots of vehicle 110 more
Secondary detection, to determine 110 corresponding pressure drop threshold value of each bonding dots according to the big data to this detection.Staff can root
According to determining pressure drop threshold value by inputting each 110 corresponding pressure drop threshold value of bonding dots of key-press input on display module 180；When
It, can be directly by showing that display screen inputs each 110 corresponding pressure drop threshold of bonding dots when display module 180 is touching display screen
Value.
Optionally, 110 number of faults threshold value of bonding dots, fault verification submodule are prestored in data processing module 130
133 are additionally operable to, when detecting that 110 quantity of failure bonding dots is greater than or equal to 110 number of faults threshold value of bonding dots, judge bonding
There are failures for datum mark 111.
Because the breakdown judge of all bonding dots 110 is all absolute according to the bonding dots 110 and the pressure drop of bonding datum mark 111
Value judges, therefore when bonding 111 failure of datum mark, the testing result of each bonding dots 110 is all inaccurate, and most of
Bonding dots 110 can be judged as failure bonding dots.Therefore bonding dots number of faults threshold can be prestored in data processing module 130
Value, when fault verification submodule 133 detects that failure bonding dots quantity is greater than or equal to bonding dots number of faults threshold value, judgement
There are failures for bonding datum mark 111.Optionally, number of faults threshold value is more than or equal to the 1/2 of 110 total quantity of bonding dots.I.e.
When fault verification submodule 133 determines half or the bonding dots of more than half 110 all have failure, bonding benchmark is judged
Point 111 is failure bonding dots, and failure bonding dots quantity is set to 1.Display module 180 is then transmit to be shown.Failure
Amount threshold can also be configured according to actual conditions by display module 180.
Optionally, data processing module 130, which is additionally operable to detect each bonding dots 110 successively upon power-up of the system, whether there is
Failure, and control disconnects each bonding dots 110 and corresponding detection line 120 after the completion of multiple bonding dots 110 all detection
Electrical connection.
The automobile-used bonding detecting system detects for the monocycle, i.e., detects each bonding dots 110 successively after the power is turned on, and diagnosis is completed
Afterwards, 130 inside of data processing module is automatic disconnects bonding dots detection line 120, and high current produces it when vehicle launch being avoided to run
Raw impact, damages module.Such detection mode both may be implemented the high-frequency each bonding dots 110 of detection and whether there is failure,
Or it will break down and (there is paint or dirty when such as bonding dots 110 are in corrosion initial stage or bonding dots 110 are got one's things ready online vehicle
It is dirty)；Consumption system charge that again will not be excessive.
The technical solution of the present embodiment obtains the bonding dots voltage value with each bonding dots by data acquisition submodule,
The bonding datum mark voltage value of bonding datum mark；Fault verification submodule is detecting that bonding dots state bonding dots voltage value and bonding
When voltage difference absolute value between the bonding datum mark voltage value of datum mark is more than the bonding dots corresponding pressure drop threshold value, judgement should
Bonding point failure, and fault point is transmitted to display module and is shown；And it is more than number of faults in failure bonding dots quantity
When threshold value, judge bonding benchmark point failure, facilitate malfunction elimination, foundation is provided to exclude the failure because of caused by bad earth.
After realizing overall wire sheaves entrucking, the detection to the bonding dots of overall wire sheaves and body earth improves vehicle operational reliability,
And further improve detection accuracy.
