In general, if the cold lasts two to three days in winter, when temperatures drop below 5 degrees Celsius, water related to water in the house, such as pipes exposed to the outside air, water tanks installed on the rooftop, water pipes and water meters in apartments or detached houses, Frequent freezing of the facility freezes and causes many problems such as leakage.

Freezing accidents of water pipes and water meters are increasing every year due to unpredictable weather due to extreme weather. First, freezing accidents of water pipes and meters are as follows: First, the economic burden of leakage due to water leakage and installation cost of water pipes and water meter. Secondly, the use of tap water is impossible, so that drinking water, washing, and toilets are not available. Also, the boiler is not operated and the heating is not performed, which paralyzes normal life. There is a problem that can cause life injuries due to impaired traffic and slippery due to freezing of water.

The freeze phenomenon is that the water contained inside the water pipe is filled with water, and when the outdoor temperature is low, such as in winter, the water contained in the water pipe freezes and its volume increases, which causes the water pipe to break while the space inside the water pipe expands. In order to prevent such freezing accidents, the exposed water pipes have been constructed with insulation or used clothes, cloth, etc. to prevent freezing.

However, when warming with old clothes, cloth, sawdust, chaff, etc., the old clothes, cloth, sawdust, chaff, etc. absorb moisture and freeze together. Insulating material does not melt, so there is a problem of promoting the freezing, so to solve the freezing problem of the water pipe, various types of insulation and coating material surrounding the water pipe is being developed.

However, if the insulation of the material such as styrofoam or sponge is buried in the ground, there is a problem of soil pollution, or environmental pollution problems such as air pollution when incinerated, and if replaced annually, waste disposal problems occur.

 In addition, in the previous stage of freezing phenomenon, the water flow starts to freeze somewhere in the water pipe, and if the water does not come out immediately, find the place where it started to freeze and heat the frozen area with a heating means such as a torch before the water pipe is frozen and damaged. Urgent action is needed to make it available.

On the other hand, there are resources that are supplied by public companies and utilized to maintain a smooth life and activities in each home or workplace, for example, electricity, water, city gas.

It is no exaggeration to say that these resources are the minimum necessary for modern people to live.

These resources, like other goods, must be purchased at a certain cost, and the purchase amount is set based on the amount used in each household or business at the base price.

Therefore, each home or workplace is equipped with a meter that can detect the amount of water, city gas, electricity, etc., and the scale of the meter rotates according to the amount of usage, so that the total accumulated amount of usage can be known.

Therefore, gas meter, water rate, electricity rate, etc. according to the used amount of the meter were charged using the method that the meter readers visited the head of household or workplace periodically and checked the meter reading.

 However, it is not easy for the meter readers to visit each home and business at once, and the usage of each home and business is not easy to be aggregated. As a result, it has been difficult for suppliers such as water, city gas, and electricity to easily check the total supply and profits based on a specific date, false or misreading of the meter reader, and crimes that set the meter in charge. .

Therefore, a remote meter reading system has been proposed to improve this problem.

The remote meter reading system installs an automatic meter including a meter in each home and workplace, and periodically sends meter reading signals from the meter to a remote meter server that manages meter data remotely. At the same time, the inconvenience of having to do it, and the advantages of checking the usage of each home and business at a specific date and time at the same time, and the integrated meter reading of electricity, water, and city gas, reduce labor costs and make false or false In addition to preventing the meter reading, there is an effect of protecting the privacy of the consumer by eliminating the crime prevention and the visitor visited by the reader.

However, these wireless meter reading is difficult to apply to real life because there is a problem to secure the power required for the wireless communication and the insulation system that prevents freezing accident of water pipes as well as a large installation cost for supplying power from a separate generator or the outside.

Without a separate generator or supplying power from the outside, sufficient power cannot be efficiently obtained by itself, and even if it generates power by itself, power is not supplied when water, gas, etc. are not used.

In the above, it is to be supplied to the power of the communication unit 24 for transmitting and receiving the electrical energy generated by the self-powered power supply unit 10 to the outside.

Even without receiving a separate power supply from the outside, the mechanical energy generated by the flow of fluids such as city gas or water is connected to the rotating impeller and the generator to generate electricity, thus producing efficient electricity. The production capacity is maximized and it is stored in the storage battery so that it does not use water or city gas, so it is possible to secure sufficient power even without generating power. Therefore, it is possible to prevent the freezing of water pipe during winter by using heating elements such as heating wire. The wireless communication can be performed smoothly by supplying the power to the driving power of the meter reading member such as a digital meter and the power of the communication unit for transmitting and receiving data to and from the outside.

Therefore, it checks the temperature of water pipes by itself to prevent freezing waves in advance, and it is possible to reduce costs and quick and accurate meter reading by automatic meter reading through wireless communication without reading the amount of water and gas consumption. The installation cost is reduced because there is no need to install a power line to power the gas meter.

  In addition, by enabling integrated meter reading of electricity, water, and city gas, it not only reduces labor costs and prevents false or false meter readings, but also protects the privacy of consumers by eliminating crime prevention and visitor visits by meter readers. It works.
