It is set to be directed at heat source thermo, record current data is temperature measurement data first；
(3-2) control mobile terminal stops movement after moving forward certain distance, adjusts infrared thermal imaging equipment angle, obtains
Take second of heat source temperature data；
(3-3) and then control mobile terminal move forward again, get third time heat source temperature data；
(3-4) thermal source data acquisition finishes and then carried out across comparison three times, is floated with the change of angle as heat
Source, on the contrary it is reflective spot, reflective spot is excluded.
In the step (3-4), floated with the change of angle in the range of 0 degree~3 degree for thermal source.
The specific method of the step (4) is：
The position of this reflective spot and temperature information recorded thermal source number by (4-1) when it is reflective spot to identify pyrotoxin
According in Exclude Lists；
(4-2), will not if this thermal source information is found in Exclude Lists when mobile terminal is re-moved to herein
Thermal source identification is carried out again, directly ignores this thermal source, continues to move.
Beneficial effects of the present invention are：
(1) by the implementation of this method, when using portable infrared thermal imaging technique, the surface of the cable in tunnel is monitored
It is thermal image by the reaction of cable surface Temperature Distribution during temperature change；
(2) the reflective spot interference of the thermal imaging in tunnel can effectively recognize and exclude by the present invention, prevented
Only due to reflective spot disturbs and caused by erroneous judgement operation on related service logic, reliability is high.
