Description

Remote meter reading measuring device based on power line communication

The present invention relates to a measuring device for remote meter reading, in particular, easy to install, electrically safe, can be used in a power cable having a variety of diameters, can reduce the construction cost without impairing the appearance of the pole, The present invention relates to a power meter communication-based remote metering measurement device that can be applied to both electric poles and electric power meter boxes of electric power.

In general, a remote meter reading system refers to a system that transmits data through a communication network by converting a measurement result into an electrical signal from a measurement target at a distant point and processes the data at a terminal.

Remote meter reading has been developed as a new information and communication service with the development of communication technology, sensing technology and computer technology, and recently, it is widely used in pollution monitoring, methods, disaster prevention, power, water supply and gas system.

Such a remote meter reading system is classified into a wireless method without a communication line and a wired method with a communication line according to a communication method used.

Here, the wired method is classified into a power line method, a cable method, a dedicated line method, and a telephone line method according to the type of communication route used.

In this case, the power line method is a method using power line communication (PLC), and uses a power line used to supply electricity to a home, a factory, or an office in a power company as a signal transmission path.

The power line communication is a method of communicating data through a power line using a commercial AC signal as a transmission medium. Since a sinusoidal wave of 60 Hz, which is commercial AC power, and a communication signal (for example, several tens of KHz) are multiplexed and transmitted simultaneously, Communication is possible wherever power is supplied.

However, currently applied power line communication method is a probe connected to the power line in order to add a communication signal to the power line, or extract the communication signal from the power line is located close to the transformer or close to the consumer electronics or lamp in the customer have.

Therefore, various harmonics such as corona and noise are generated from a transformer or a home appliance, and thus there is a problem in that the amount of power is not properly detected.

This prevents the remote meter reading itself or the reading of the data itself. However, the meter reading rate tends to get better in the early morning when there is no electricity use.

In order to solve this problem, a noise filter has been attempted, but since the communication signal and the noise are attenuated together, most of the remote meter reading by the power line communication is actually performed.

1 is an exemplary view showing a measurement device for a remote meter reading based on the conventional power line communication. Referring to FIG. 1, a conventional meter reading apparatus for remote meter reading based on power line communication includes a probe 10 for piercing a power cable installed in a pole P, and a lower portion of the probe 10 and a pole P. An electric wire 20 for connecting the housing 50 installed on the side, a flexible conduit 30 surrounding the outer diameter of the electric wire 20, and a metal film band 40 for supporting the conduit 30 Consists of components,

In this case, the housing 50 accommodates a coupler 60 and an earth leakage breaker 70 for extracting only a PLC signal.

Such a conventional power meter communication device based on the power line communication has a disadvantage that hinders aesthetics because the complex parts must be installed in the electric pole (P), and also the installation is complicated and difficult due to the installation of various components There is a problem that the construction cost is very high due to the installation of the parts.

In addition, as a result of piercing a power cable having a diameter of various sizes, there is a very dangerous problem in that an electric shock occurs due to a gap between the screw of the probe P and the power cable.

In addition, since only one large probe 10 is used from the beginning to pierce a power cable having a large diameter, there is a disadvantage in that it cannot be applied to a small-only electricity meter box having a small place.

That is, the operation costs are inevitably increased to manufacture and operate the probes 10 having different sizes, which are pierced from the small diameter to the large diameter, and if the small probe 10 for the KEPCO is separately manufactured, This also has a problem that the operating costs must rise.
