With value come judge to obtain grounding resistance that water is rinsed in vehicle ground system whether the result of failure, therefore with raising system peace
The technique effect of full judging efficiency.
Further alternatively, the processor, in the current first resistor value R1More than or equal to second resistance
During threshold value, the Resistance Fault of first load device is determined, controls the warning device to send and characterizes the first load dress
The warning message for the Resistance Fault put；And/or in the second resistance value R2During more than or equal to 3rd resistor threshold value, it is determined that described
The Resistance Fault of N number of wheel group, the warning device is controlled to send the warning message for the Resistance Fault for characterizing N number of wheel group.
The second resistance threshold value and the first resistor threshold value are similar, can be equally systemic presupposition, characterize negative
Carry put because loose contact or welding quality it is bad, vibrations cause short circuit, burn into pollution caused by resistance greatly increase when and answer
The threshold value met or exceeded, user can voluntarily be set according to different application environment or different need.
The 3rd resistor threshold value is equally similar with the first resistor threshold value, can be systemic presupposition, characterize more
Individual wheel group because loose contact or welding quality it is bad, vibrations cause short circuit, burn into pollution caused by resistance greatly increase when and answer
The threshold value met or exceeded, user can voluntarily be set according to different application environment or different need.
That is, when processor determines there is a first resistor value and second resistance value R2And value R be more than or equal to institute
After stating first resistor threshold value, then it may proceed to judge the first resistor value, that is, the current first resistor value R1It is whether big
In equal to the second resistance threshold value, if so, can then determine and the current first resistor value R1Corresponding first load dress
Put and failure be present, processor can control warning device to send and characterize the warning message that first load device has failure, work
Make personnel directly can carry out maintenance processing according to the warning message to first load device.
On the other hand, when processor determines the current first resistor value R1And not less than the second resistance threshold value after,
The second resistance value R can then be determined whether2Whether the 3rd resistor threshold value is exceeded, if so, can then determine described N number of
Failure in wheel group be present, processor can control warning device to send and characterize the warning message that N number of wheel group has failure, work
Personnel directly can carry out maintenance processing according to the warning message to N number of wheel group.
It can be seen that the technical scheme in the embodiment of the present application can determine the current first resistor value R by processor1Or
It is the second resistance value R2Whether exceed default resistance threshold and determine the equipment specifically to break down, so as to pass through place
Reason device control warning device sends the warning message of the equipment of embodiments guilty culprit, therefore the technology in the embodiment of the present application
Scheme also has the technique effect for improving warning message applicability.
Still optionally further, the processor, to be more than or equal to the 4th resistance threshold in the resistance value R of the grounding resistance
When being worth and being less than or equal to five resistance thresholds, determine the grounding resistance loose contact in the water flushing vehicle ground system or set
Mistake is equipped with, controls the warning device to send and characterizes the grounding resistance loose contact or wrong warning message is set, wherein,
5th resistance threshold is less than the first resistor threshold value.
4th resistance threshold and the 5th resistance threshold are equally similar with the first resistor threshold value, Ke Yiwei
The resistance threshold of systemic presupposition, the 4th resistance threshold to the resistance range between the 5th resistance threshold can characterize described
Load device and/or the wheel group are in loose contact or device and set failure, or other circuits such as release at the non-normal working shape
It should reach during state or residing threshold range, user can voluntarily be set according to different application environment or different need.
That is, the technical scheme in the embodiment of the present application can also judge that load device and wheel group are by processor
It is no in loose contact or device failure to be set or the abnormal operating states such as other circuits release, so as to control warning device
Send corresponding warning message, it is seen then that the technical scheme in the embodiment of the present application also has the technology for further improving applicability
