Description

Transparent optical transmission medium consisting of metering devices for metering and method for the preparation according to the present invention.

The present invention relates to a meter reading device for supplying (transmitting) an image by photographing the meter part of the meter so that the meter part (display part) of the meter can be checked at a long distance, and in detail, using a camera provided to be built in. It is installed so that the meter part of the meter can be taken, but the air layer between the camera and the meter part can be minimized and the structure can be simplified while preventing the metering restriction caused by moisture infiltration and condensation due to temperature change. It relates to a meter reading device made of a transparent light transmission medium and a method of manufacturing the same.

A water meter is a device that accumulates the amount of water used by a user and is usually installed in the water pipe buried in the underground of indoor or outdoor of the customer. On the outside of the water meter there is also a protective box for protecting the water meter. When the meter is installed indoors, the meter reading meter must check the indoor meter and obtain the permission of the customer. Therefore, there is a problem that the meter can not be read when there is no person in the room. Even if the meter is installed outdoors, It was inconvenient to open the cover of the protective compartment buried in one place and to check the meter part of the water meter.

In order to solve the above problems, there have been proposed various water meter automatic meter reading systems in which a CCD camera is installed in a water meter and a meter reading source can meter water usage in the open water.

That is, (KR) Patent No. 10-0837428 remote meter reading device, remote metering system and remote metering method using the same, (KR) Patent number No. 10-1020083 water meter with anti-collimation function Meter Reading Device, (KR) Registered Patent Publication No. 10-1164579 Electronic Letter for Meter Reading and Meter Reading Device Using the Same, (KR) Utility Model Publication No. 20-0231394, Remote Meter Reading Device, (KR) Patent documents such as the water meter remote meter reading system 20-0310392 are provided, and various other technologies are provided.

However, in the conventional automatic meter reading system of a water meter, there is a problem that it is often impossible to perform a meter reading using an image captured by various factors such as humidity and temperature change in a camera installed for shooting a meter part of a water meter. Especially, in Korea, there are four seasons, and there are severe temperature changes, high temperature and high humidity, and dry weather, so that they can not obtain clear images due to moisture and temperature changes.

That is, in the related art, a large number of air layers are included between the camera and the meter part, and in particular, a large amount of air layers are included in the space where the camera is installed, and when the temperature changes due to moisture (moisture) contained in the air layer, There is a disadvantage in that the image captured by the camera is not clear due to condensation.

For this reason, the meter reader should be uncomfortable with the naked eye, and in order to do the naked eye, there is a disadvantage in that a part of the automatic metering system (system) installed is disadvantageous, and the meter reader is partly separated to perform the meter reading. The problem arises in that a considerable amount of time is consumed by assembling the metering device (system).

In addition, the structure of the meter reading device provided in the prior art has a disadvantage that the transparent light transmission medium, the camera and the control substrate is provided in the body of the meter reading device, the structure is complicated and the production cost and its cost is expensive. On the other hand, there are disadvantages such as condensation or the like occurring in the camera due to wet air penetrating into the internal space of the meter reading device.
