Due to needing the water level information for detecting diverse location, therefore, maintainer's offer data foundation is given into raw ponding information is convenient.
Embodiment eight
Referring to Fig. 8, display unit 5 is added on the basis of a upper embodiment, for showing the ponding information；
While above-mentioned ponding information is obtained, by the way that display device, such as LCDs, mobile terminal is being locally located
Above-mentioned ponding information is shown, when display unit 5 is mobile terminal, the mobile terminal is connected with the communication of network control unit 4.This
Sample can not only make driver and conductor understand ponding information, and be easy to assign corresponding maintainer to go to corresponding water level monitoring
Leak equipment is handled near device.
Embodiment nine
A upper embodiment basis on control unit 1 add function, i.e. described control unit 1 be used for receive change
After the instruction of first watermark threshold, first watermark threshold is changed；
Because the equipment of vehicle interior is different for the ability to bear of ponding, therefore, for the first water of different equipment
Position threshold value difference, therefore, the present invention can meet difference of the whole vehicle for water level by changing the first watermark threshold
Tolerance.
Embodiment ten
A upper embodiment basis on control unit 1 add function, i.e. described control unit 1 be used for receive change
After the instruction of second watermark threshold, second watermark threshold is changed；
Because the equipment of vehicle interior is different for the ability to bear of ponding, therefore, for the second water of different equipment
Position threshold value difference, therefore, the present invention can meet difference of the whole vehicle for water level by changing the second watermark threshold
Tolerance.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
