The heating element 300 is configured as a resistor such as a heater to emit heat. The heating element is located at the front end of the conductive pipe 500, and the heat dissipated is transferred to the heat target shape module along the conductive pipe 500. In order to allow the heat generated from the heating element 300 to have a multi-step heating temperature according to the current control of the heating operation unit 210, the heating control can be variably controlled. In addition, the area size of the heating element 300 is larger than the area of the heat target shape module.

The heat generating controller 210 is a driving driver that drives the heating element, and adjusts the amount of current provided to the heating element so that the heating control is performed. Control the amount of heat generated by the heating element according to the heating control data provided from an external server (not shown) through the system interlocking unit 100. For example, it is possible to control the heat generation temperature of the heating element in three steps of upper, middle, and lower. The margin of error of the stepwise temperature can be designed to ± 2 ° C or less.

The opening and closing plate 410 is positioned in the form of a plate plate on the top of the heating element, and serves to block or pass the heat of the heating element to the conductive tube 500. Therefore, to block or pass the heat transfer to the heat target shape module 610 located at the end of the conduction pipe 500.

Opening and closing control unit 400 controls the opening and closing of the opening and closing plate 410, by temporarily blocking the heat generated by the heating element 300 to prevent heat from flowing into the conductive tube, the heat target shape module 610 It is possible to open and close the heat emitted from. The opening / closing maximum / minimum speed of the opening / closing plate 410 controlled by the opening / closing control unit 400 is designed to move instantaneously between the heat target and the heat target. In the heat target shape module 610, the average opening and closing speed for making the heat target visible is designed to move on average between the heat target and the heat target. The opening / closing maximum / minimum / average speed is determined according to the opening / closing control data received from an external server.

The light emission controller 220 is a driving driver that controls the amount of light emitted from the light emitter 621 installed under the light emission target shape module 622 of the target display unit 600, and adjusts the amount of current provided to the light emitters such as LEDs. Allow light emission control. Controlling the amount of light emitted from the light emitter according to the light emission control data provided from the external server through the system interlocking unit 100. For example, the light emission amount of the light emitter can be adjusted in three steps of upper, middle, and lower. The error of light emission in stages may be designed to be 2 LUX or less. On the other hand, the heat generating control unit 210 and the light emitting control unit 220 is implemented as one driving chip on the PCB (Printed Cricuit Board) substrate 200, the heating value of the heating element 300 and the light emitting element 621 and light emission You can adjust the value together.

The conductive tube 500 has a structure of a tube protruding from the body of the housing 10 to supply heat radiated from the heating element to the infrared image detector. The conduction pipe 500 has a hollow passageway, so that the heat of the heating element 300 located at the front end of the conduction pipe 500 is located at the end of the conduction pipe 500 along the inside of the conduction path. It can be delivered to the target shape module 610. By having the structure of the conductive tube 500 as described above, the body of the housing 10 can act as a gripper of the user, it is possible to easily touch the end of the conductive tube 500 to the image detector.

The target display unit 600 functions to generate heat emitted from the heating element 300 in the form of a target, or emit light emitted from the light emitting element 620 in the form of a target. To this end, the target display unit 600 includes a heat target shape module 610 and a light emitting target shape module 620. The thermal target shape module 610 and the light emitting target shape module 620 are formed to have a size that can be input to the infrared sensor and the visible light sensor that detects the minimum.

The target display unit 600 including the thermal target shape module 610 and the light emitting target shape module 620 is positioned at an end surface of the conductive tube 500. The target display unit is positioned on the end surface of the conductive tube so that an image detector (infrared detector, visible light detector) can easily detect the heat target shape module 610 and the light emitting target shape module 620 located at the end surface of the conductive pipe 500.

The heat target shape module has a structure formed as a specific shape at the end surface of the conductive tube. For example, as illustrated in FIG. 3A, the heat target shape module 610 may have a vehicle shape. The heat of the heating element located at the front end of the conductive pipe is conducted along the conductive pipe 500, so that the temperature of the heat target shape module 610 in the form of a vehicle is increased. The conductive pipe end surface 501 other than the heat target shape module is insulated. This is to prevent the heat temperature of the heating element from appearing at the end face 501 of the conductive tube other than the heat target shape module. The infrared detector may detect a temperature in the heat target shape module 610 and output an infrared image of a vehicle shape. Therefore, by controlling the temperature value in the heat target shape module 610 step by step, or on / off, it is possible to verify the performance of the infrared detector.

Meanwhile, the heat target shape module 610 may have various shapes such as a square, a triangle, a tank, an airplane, a ship as well as a vehicle, and may be implemented as a plurality as shown in FIG.

It must be anodized. This is to protect the infrared sensor of the infrared detector from the heat of the heating element.

On the other hand, in the light emitting target shape module 620, a plurality of light emitting bodies such as LEDs are formed on a part of the end surface 501 of the conductive tube. The light emitter may emit light on / off according to the control of the light emission controller and may vary the amount of emitted light. The visible light detector may detect light emitted from the light emitting target shape module and output a visible light image.

The light emitting target shape module 620 may also be implemented to have various light emitting forms by varying the shape of the light emitting body. In addition, by varying the number of light emitters, the performance of the visible light detector can be verified by alternately emitting a plurality of light emitters alternately.
