Background technique
Common electric tracing temperature controller is made of heating device and temperature sensor, heating device by heating power supply and
Generate heat cable composition, temperature sensor is then thermocouple probe, when operator temperature controller setting expectation reach temperature or
Person's heating time, open heating power supply, by mounted in fever cable on thermocouple probe monitor temperature, temperature reach the time or
Heating time stops heating to power supply is switched off, and current this mode has the disadvantage that thermocouple temperature sensor can only pacify
Mounted in the nearly controller end of fever cable, need to power, can not install at a distance, at the same temperature sensor without hair enter very deep water bottom or
Oil well bottom etc.；Thermocouple temperature sensor is point type sensing, and the temperature that only measurement fever cable is put individually, measurement result can not
Completely reflect the temperature distribution state of whole section of fever cable, fever cable temperature tends to vary with the variation of contact medium and distribution is presented not
, therefore as temperature as heat tracing stop condition seem inaccurate；It is unable to monitor fever cable health status, is made in real time
Fault pre-alarming, fever cable is easily-consumed products, can accelerate its aging even in the case where comparing harsh conditions using frequent or use environment
Breakdown.
Summary of the invention

Set can carry out temperature measurement to rugged environment and be controlled by temperature control module by heating module according to the temperature information measured
The cable that generates heat heats；Temperature-measuring optical fiber is using being spirally mounted on fever cable, in the element length section of each setting on cable of generating heat
It is interior to measure multiple temperature informations, the temperature resolution of the thermo parameters method information measured is substantially increased, thermometric information is more
Add accurate reliable；Entire thermometric process be to the whole real-time temperature measurement of fever cable progress, temperature measurement information more fully,
Can be according to whole generate heat cable thermal self-restraint stress, minimum point and average value as the foundation for closing heating device, temperature controls more
Add accurate；Barrier module real-time monitoring temperature-measuring optical fiber is sought by the optical fiber being made of optical time domain reflectometer fracture whether occur, squeeze
The failures such as deformation and coiling bending, test seeks barrier module by optical fiber and tests the strong of entire temperature-measuring optical fiber at the beginning of temperature-measuring optical fiber installation
Health situation checks whether that there are excessive, the debuggings that link attenuation coefficient occurs of decay events or a certain section there are partial points
The optical time domain reflectometer optical signal curve of temperature-measuring optical fiber is recorded afterwards and as datum curve, need before temperature controller starting heating
It first carries out optical fiber and seeks barrier test, the curve that temperature-measuring optical fiber measures does not have decay events and datum curve comparison result to be consistent
