Meanwhile, according to the present invention, a dust measuring means is installed in a CCTV to detect dust through the dust measuring means, and when dust above a standard is detected, it is output through an automatic communication signal output unit to notify that fine dust is above the standard.

The dust measuring means 1000 of the present invention is positioned so as to face an infrared transmission means (A) for emitting infrared rays, and the infrared transmission means, and receives light emitted from the infrared transmission means according to the degree of the received amount. Infrared receiving means (B) for determining the inflow of dust, and dust measurement control section for controlling the input voltage of the infrared transmitting means (A) to increase when the output voltage of the infrared receiving means (B) is less than a set value It includes (C).

Further, the infrared transmission means (A) receives the infrared transmission control signal from the dust measurement control unit (C), determines the infrared transmission amount, and outputs the changed infrared transmission amount.

That is, when the result value of the infrared receiving means (B) is transmitted to the dust measurement control unit (C), the dust measurement control unit (C) predicts the amount of dust generated based on the data of the infrared receiving unit (B), and By outputting a control signal to the infrared transmission means (A), the amount of infrared transmission is adjusted to induce output.

In other words, the dust measurement control unit reads the light quantity data output from the infrared receiving means, and based on this, the light quantity of the infrared light emitting means is automatically controlled so that the sensitivity control is automatically kept constant. It is designed to be able to measure by maintaining it in a sensitivity state.

In other words, if the amount of light received by the infrared receiver (B) is weak, the dust measurement control unit (C) determines that the degree of contamination is high, and outputs a control signal to increase the amount of light from the infrared transmitter (A) for more precise dust measurement. And, if the amount of received light of the infrared receiving means (C) is too much, the state without contamination or precise measurement becomes difficult, so that a control signal is output to reduce the amount of light of the infrared transmitting means (A). That is, it is necessary to maintain the amount of infrared light transmitted in an appropriate state. Only then can the amount of infrared rays measured through the infrared receiving means become accurate, so that the amount of dust generated can be more accurately predicted. Accordingly, the dust amount data measured by the dust measurement control unit of the present invention can output a dust measurement result with high reliability.

The present invention includes a concave lens group (1) in which a plurality of concave lenses are mounted to limit the output of infrared rays;

An infrared transmission element (2) that is close to the concave lens group and outputs infrared rays;

It is installed on one side of the concave lens group to allow the concave lens group to flow to control the infrared output, but if the ambient temperature is high according to the amount of temperature change, the concave lens group is moved to the left so that infrared rays pass through the lens with a low depression angle. A shape memory spring (3) which controls the output to increase and controls the infrared output to decrease by allowing the concave lens group to flow to the right when the ambient temperature is low so that infrared rays pass through the lens having a high depression angle;

It comprises a fixing part 4 located at the right end of the shape memory spring to support the movement of the shape memory spring.

And, a housing (5) for accommodating the spring and the fixing portion;

It is installed on the inside of the housing, but is installed on one side of the shape memory spring and forcibly expands the shape memory spring through heat generation to move the concave lens group to the left, thereby allowing infrared rays to pass through the lens with a low depression angle to output infrared rays. A heat generating means (6) for inducing the force to increase;

It is installed on the inside of the housing, but is installed on the other side of the shape memory spring (3) to transfer cooling heat to force the shape memory spring (3) to contract to move the concave lens group to the right. A thermoelectric element 7 for inducing an infrared output to be forcibly lowered by allowing the infrared rays to pass through;

A transmission control unit (8) that is electrically connected to the heating means and the thermoelectric element and controls to increase the infrared output by operating the heating means when there is a lot of dust, and operates the thermoelectric element to lower the infrared output when there is little dust. It consists of including.

In addition, a plurality of holes 5a, 5b 5c are formed in the rim of the housing in which the fixing part 4 is located, and a magnet 9 for setting the position of the fixing part 4 is inserted into the hole. Done.

That is, the fixing part 4 is made of metal, and the fixing part is temporarily fixed by inserting the magnet 9 into the hole. Accordingly, in areas with low temperature, the magnet is placed in the central hall (5b) or the left hole (5a), and in areas with high temperature, the magnet (9) is placed in the central hole (5b) or the right (5c). do.

Then, the location of the first transmission element 2 is located in the center of the concave lens group 1, and then expands and contracts appropriately according to temperature changes, so that the concentration of dust can be accurately determined.

In the present invention, the output of the transmitting element 2 is automatically adjusted according to the change in temperature. The shape memory spring 3 is set to a basic temperature, and when the temperature increases, the shape memory spring increases, The light is output by reducing the light, and when the temperature decreases, the shape memory spring 3 decreases and the light of the transmitting element 2 is lowered to output.

In other words, since the dust is distributed in the gas, the movement becomes active when the temperature rises, so it is possible to check the more precise dust concentration than when the output of the transmission device 2 is lowered, and when the temperature decreases, the movement becomes dull. You can check the dust concentration more precisely than when the output of 2) is increased.

Accordingly, the present invention allows the concave lens group 1 to flow to reflect the temperature change so that the dust concentration can be more accurately identified.

Looking at the actual operation, first, light of the transmitting element is outputted through the third concave lens 1c installed at the center of the concave lens group 1 basically.

And, when the ambient temperature rises, the shape memory spring expands so that the second concave lens 1b is located on the right side of the third concave lens 1c, and the second concave lens 1b has a lower depression angle than the third concave lens 1c. Accordingly, the light output of the transmission device 2 is lowered and output is performed. And, when the ambient temperature decreases, the shape memory spring 3 contracts and is located on the left side of the third concave lens 1c, and at the same time, the fourth concave lens 1d having a higher depression angle than the third concave lens 1c is transmitted. It comes to the position of the element 2, and accordingly, the light output of the transmission element 2 is increased to output.

As described above, according to the present invention, the shape memory spring 3 automatically expands and contracts in response to the ambient temperature, thereby promoting a change in the amount of light according to the movement of the dust, so that a more precise dust concentration can be identified, and a more accurate alarm output. This is done.

On the other hand, the present invention is configured so that the transmission control unit 8 forcibly moves the concave lens group 1 according to the dust concentration to determine the most accurate dust concentration. Even if there is no temperature change, the amount of light of the transmitting element is adjusted according to the dust concentration. It was adjusted so that the exact concentration of dust could be determined.

That is, the present invention drives the heating means 6 and the thermoelectric element 7 by recognizing the dust measurement controller C when the control signal is output to facilitate the change in the amount of light of the infrared transmitting means. Thus, the most appropriate infrared transmission was made.

First, the infrared light is basically output through the third concave lens 1c installed at the center of the concave lens group 1, and when the infrared light is to be output by a little reduction, the transmission control unit 8 is used as the heating means 6 ) To generate heat so that the shape memory spring expands, and the transmission element (2) is fixed accordingly, so the concave lens group (1) moves, but the second concave lens (1c) is installed on the right side of the third concave lens (1c). As the lens 1b moves to the position of the transmitting element 2, the output light of the transmitting element is output through the second concave lens.

And, when it is necessary to reduce the infrared light more and output it, the transmission control unit 8 activates the heating means 6 to generate more heat so that the shape memory spring 3 expands more, and accordingly, the concave lens group 1 ) Is moved, but the first concave lens 1a is heated to move to the position of the transmitting element 2, so that the light of the transmitting element 2 is output through the first concave lens 1a.

In addition, when the infrared light is to be increased and output is required, the transmission control unit 8 drives the thermoelectric element 7 to generate cooling heat so that the shape memory spring 3 contracts, and the concave lens group 1 moves accordingly. The fourth concave lens 1d, on which the left side of the 3 concave lens 1c is installed, is positioned on the transmission element, and accordingly, the light from the transmission element 2 is output through the fourth concave lens 1d.

In addition, when the infrared light is to be output higher, the transmission control unit 8 drives the thermoelectric element 7 to generate more cooling heat so that the shape memory spring 3 contracts more, and accordingly, the concave lens group 1 ) Is moved, but the fifth concave lens 1e is moved to the position of the transmitting element 2, and accordingly, the light of the transmitting element 2 outputs light through the fifth concave lens 1e.

In addition, the concave lens group is designed to vary the degree of output of infrared light according to the depression angle of the center, and the third concave lens 1c is basically installed at the center of the operating rod and has a depression angle of 25 degrees.

In addition, the second concave lens 1b is used when the infrared light is to be output by slightly reducing the infrared light, is installed on the right side of the third concave lens 1c, and has a depression angle of 15 degrees.

In addition, the first concave lens 1a is used when the infrared light is to be further reduced and output, and is installed on the right side of the second concave lens 1b, and has a depression angle of 5 degrees.

In addition, the fourth concave lens 1d is used when the infrared light is to be further increased to be output, is installed on the left side of the third concave lens 1c, and has a depression angle of 35 degrees.

In addition, the fifth concave lens 5e is used when it is necessary to increase the infrared light to be output, and is installed on the left side of the fourth concave lens 1d to form a depression angle of 45 degrees.
