Wherein, first default value is greater than second default value.
7. a kind of detection device of fuse state, which is characterized in that including infrared sending device, the first infrared receiving set,
Timing unit and control unit as claimed in claim 1 or 2；The infrared sending device and first infrared receiving set
It is oppositely arranged and is located at the lower left and lower right of the fuse of fuse；First infrared receiving set is described molten
When silk is unblown, the infrared signal can be normally received；First infrared receiving set, cannot in the fuse failure
Normally receive the infrared signal；The infrared sending device, first infrared receiving set and the timing unit with
Described control unit communication connection；
The infrared sending device, for being sent in current sensing time point red after timing unit timing reaches timing time
External signal；
First infrared receiving set, for receiving the infrared signal.
8. detection device according to claim 7, which is characterized in that further include communication unit；
Described control unit is also used to the current fuse state information being sent to communication unit；
The communication unit is set for the current fuse state information to be sent to reception by wireless self-networking mode
It is standby.
9. detection device according to claim 8, which is characterized in that further include the second infrared receiving set；Described second
Infrared receiving set and the infrared sending device are located at the same side；
Second infrared receiving set returns to the infrared sending device side after reflection for receiving the infrared signal
To part signal；
Described control unit is also used to obtain the second infrared receiving set in the second reception knot of the current sensing time point
Fruit determines the state of fuse according to second reception result, if the fuse in the current fuse state information
State is identical as the state of the fuse, and the current fuse state information is sent to communication unit；Wherein, described
Second reception result includes receiving time when receiving the part signal.
10. detection device according to claim 8, which is characterized in that described control unit is received according to described first
As a result and the device id is also used to after generating fuse state information:
Obtain the fuse state information of the upper detection time point after timing unit timing reaches timing time；
If the current fuse state information is not identical as the fuse state information of upper detection time point, work as by described in
Preceding fuse state information is sent to communication unit；
If the current fuse state information is identical as the fuse state information of upper detection time point and reaches data
When reporting time point, the current fuse state information is sent to communication unit.
