The precision of system, the precision of the night vision system after improving fault restoration.
In addition, being based on night vision system calibration facility in operator, the night vision system after fault restoration is demarcated
In the process, the temperature of 9 available second temperature sensor 13 heat generating member 2 detected of above controller.For example, if heat generating member
2 temperature is more than the first preset threshold, then controlling electric pressure converter 10 reduces the supply voltage of heat generating member 2.If the temperature of heat generating member 2
Degree is lower than the second preset threshold, then controls the supply voltage that electric pressure converter 10 improves heat generating member 2.By the above-mentioned means, can be with
Make the temperature of heat generating member 2 is more constant to maintain in preset temperature range, to ensure that night vision system, can when being demarcated
The infrared radiation that accurate detection is distributed to heat generating member 2 improves calibration efficiency and accuracy rate.
If the temperature of heat generating member 2 does not exceed only the first preset threshold also when being more than high temperature threshold value, controller 9 controls voltage and turns
Parallel operation 10 stops being that heat generating member 2 is powered, and burns to avoid in night vision system calibration facility overheat.
Further, above controller 9 is additionally provided with preset duration, the preset duration specifically can according to night vision system into
It is determined the time required to rower timing.Therefore, above controller 9 can also be while the first indicator light 14 of control be always on, record
The fever duration of heat generating member 2, when adstante febre is long is greater than or equal to preset duration, control electric pressure converter 10 stops being heat generating member
2 power supplies.In this way, it can make night vision system calibration facility after night vision system completes calibration, be automatically stopped work, nothing
Need operator that night vision system calibration facility is turned off manually.
Night vision system calibration facility provided by the utility model, when can provide night vision system for night vision system and being demarcated
The required target heater used, so that carrying out the night vision system after fault restoration can be marked based on the target heater
