Description

[0001] Meter reading device of dual structure [0002]

[0001] The present invention relates to a metering meter probe which is installed in a meter such as a water meter and is equipped with a camera and is capable of meter reading from a long distance. More particularly, the present invention provides a dual structure body, (Sealing) means so as to solve the problem caused by the temperature change and to prevent penetration of moisture easily.

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, a remote meter reading device of a meter, a remote meter reading system and an remote meter reading method using the meter, which is disclosed in Korean Patent Registration No. 10-0837428, (KR) Patent Registration No. 10-1020083, a meter meter having a fog prevention function (KR) Registered Patent Publication No. 10-1164579, which is an electronic nameplate for meter reading, and a meter reading device using the same, registered as a registered utility model registration No. 20-0231394, registered as a utility model registration device (KR) No. 20-0310392, which is incorporated herein by reference in its entirety, and various other techniques 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.

To overcome these shortcomings, many applicants, including the present applicant, are making efforts to provide various technologies.

In addition, in the conventional meter reading device, the light transmitting member is accommodated in the body, and a problem that adverse effects are imposed on the photographing such as condensation at a portion where the light transmitting member is in contact with each other due to the temperature difference between the body and the light transmitting member .
