DEG C, although optical fiber distributed type thermometric can carry out all fronts thermometric to the cable that optical fiber is contacted, and accomplish to record in real time, not
The too suitable measurement to cable intermediate joint or terminals；Infrared contactless temperature-measuring is interfered greatly by ambient enviroment, and discomfort shares
It is measured in temperature of cable junction.
Utility model content
The technical problem to be solved by the present invention is to be directed to effectively measure cable intermediate joint in the prior art
Or the defect of terminals temperature, the flexible distributed fever strip that a kind of high certainty of measurement is provided and can be extended.
Technical solution adopted by the utility model to solve its technical problems is：
There is provided a kind of flexible distributed fever strip, including conductive flexible band and uniformly distributed on the conductive flexible band
Digital Measurement of Temperature sensor；The bottom of the flexible distributed fever strip is silicone band, and the silicone band is equipped with embedded groove, described
Conductive flexible band is placed in the embedded groove；The flexible distributed fever strip further includes thermal insulation band, is laid on the conductive flexible band
Top separates adjacent digital temperature transducer.
Above-mentioned technical proposal is connect, the thermal insulation, which takes, is uniformly arranged thermal insulation item, hollow out between two thermal insulation items, the thermal insulation
The edge of band is embedded on the silicone band, and hollow-out part fills heat conductive silica gel.
Above-mentioned technical proposal is connect, one end of the flexible distributed fever strip is the waterproof connector for connecting sensor interface,
The other end is fever strip expansion interface；The unique ID number of each Digital Measurement of Temperature sensor is labeled on each conductive flexible band.
Above-mentioned technical proposal is connect, the interface type of the Digital Measurement of Temperature sensor is three-wire system or four-wire system, wherein two
Bar line is power and ground, and others are data line.
Above-mentioned technical proposal is connect, the Digital Measurement of Temperature sensor is temperature sensor or base based on single wire transmission agreement
In the temperature sensor of SMBus, I2C agreement.
The utility model generate advantageous effect be：The utility model is devised a kind of soft by flexible circuit printing technology
Property distributed temperature measuring band, the length that can increase fever strip according to actual demand increases temperature measuring point, to can realize that testee is whole
Temperature distributed measurement.On-line measurement of the utility model for temperature of cable junction can realize the entire cable connector highest temperature
Degree, minimum temperature is poor and the monitoring of mean temperature, while high certainty of measurement, actual deployment facilitate at low cost.
