The pressure difference at 5 both ends of detection main fuse, and send data to main control chip 2 in real time in the case of electricity.Main control chip 2 is receiving
Come to the data of voltage detection module, using the statistic law based on mathematical model, i.e., by calculating fuse percussion power, punching
Frequency is hit compared with number is with the default impact service life, prejudges the deterioration extent of fuse.Bus transceiver 3 is used to connect vapour
Car bus, and the real-time status of main fuse 5 is sent to automobile bus, in order to which whole-control system is made a response, including
Vehicle operator is reminded to replace main fuse 5 in time.Bus transceiver 3 includes two external pins CAN-H and CAN-L,
It is connected respectively the high position data line and low data line of CAN lines.
Power module 4 includes three external pin 12V often electricity, ON grades, ground wire.Power module 4 is direct by external pin
Vehicle power supply is accessed, its major function is that vehicle-mounted 12V power supplys are converted to 5V DC power supplies is whole automobile using high-voltage fuse
Device fault detection module is powered.Whole automobile using high-tension fuse fault detection module is in dormancy in the case of the not actuated ground of automobile
State, whole automobile using high-tension fuse fault detection module is just in running order only when receiving signal for ON grades, opens
The health status of beginning detection main fuse 5, power module 4 also receive the wake-up of vehicle bus, perform vehicle self-test before automobile starting
Function.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is set forth the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in embodiment and application range, in conclusion this specification content should not be construed as
Limitation to the utility model.
