[Technical Background of the Invention] As is well known, in rolling processing lines for steel materials, there is a canopy that detects the presence or absence of hot lumps such as red-hot slabs in order to control continuous rolling. As a means of detecting this hot mass, the infrared rays emitted from the hot mass are detected by an HMI installed at each step of the rolling lie.In Kenya-Kune, the movement of this hot mass is detected by an HMD. Efficient control of the rolling line is achieved through monitoring.

所に設けた制御箱12まで導く方式のHMDが考えられ
ている。Conventional general HMDs have the above configuration, but with the recent development of optical fibers, as shown in Figure 2, the light focused at 5/2 is separated from the thermal mass 1 by the optical fiber IS. An HMD that leads to a control box 12 installed at a location is being considered.

はこの必要がなくなる。This method has a head part 1 that focuses the light from the thermal mass 1.
Since there are no 11/C electronic components, there is an advantage that the permissible circumference can be high and it can be placed close to the thermal mass 10. Also, up until now, the main body of the HMD was cooled with water, but with the optical fiber method, this is no longer necessary.

ない。When considering the check device ratio of HMD operation in the original fiber system, if the conventional system using the check rung 7 is to be used as is, it is necessary to provide a light source in the head section 11. Light-emitting diodes or light bulbs are usually used as light sources. It is necessary to supply electricity only for this purpose, and in order to guarantee an ambient temperature of around 200"C for the head ill'4 without a cooling device, it is necessary to It is not recommended to install it due to temperature and reliability issues.

内の受光素子3で電気に変換される。The arm light blocking filter 14 is normally provided to prevent visible light from causing damage to the HMD.As shown in Figure 5, a reflective mirror is provided in the center of this filter using an arm light shielding filter 14, and the bundle fiber IJL is Reflects the light and guides it to the outer bundle fiber JJjL5
Make it. In this case, the area of reflection@1m needs to be smaller than the effective area of the visible light blocking filter 14, and the light from the inner bundle fiber tsL must be effectively reflected.
The light reflected by the reflecting mirror a is guided to the outer bundle fiber 1skL and controlled again @x2

The tip of the bundle fiber 16 is positioned and the light from the internal bundle fiber 16L is transferred to the outer bundle fiber 15.
Light is received at B. Considering the original loss, the focal length 11f of the reflection platform 11ia should be as short as possible.

でも良い。The present invention uses an optical fiber to check the operation of the HMD, including the head part 1. , Fig. 6 is a modified example of JI5 Fig. 4. The inner side of the bundle fiber shown in Fig. 4 is used for light reception, the outer side is used for light emission, and the outer bundle fiber IIL is 117E.
As shown in Figure 1, the light from the outer bundle fiber 15L is collected by the internal bundle fiber JlJRK, which is arranged in a ring shape, for example, around the fixed support 16 of the town vision cutoff filter 14, and is formed with a reflecting mirror such as Part 6-1. The method of doing so is also fine.
