Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic watt-hour meter management system including an RJ_11 connector and a DLMS / COSEM protocol using a smart phone,

The present invention relates to a system for managing an electronic watt-hour meter incorporating an RJ_11 connector and a DLMS / COSEM protocol using a smartphone, and more particularly, to a system for managing an electronic wattmeter installed in a switchboard or a home, By connecting a smartphone equipped with an app for energy measurement and self-diagnosis by a wireless communication module such as LTE, Bluetooth, Zibee, RF, etc., and using a smart phone that can meter the electricity used by the customer or self-diagnose the electronic watt- To a system for managing an electronic watt-hour meter having an RJ_11 connector and a DLMS / COSEM protocol.

It is necessary to provide smooth power supply in order to enable users of consumers such as homes and businesses to live happily lives and activities. Electricity companies such as electric power companies that supply these electric power to each customer install electricity wattages to measure the electric power supplied to each customer, and charge electric charges according to the measured values. However, there are limits to the method of imposing the electric charge by checking the watt hour meter by the meter checker when the number of the objects charged with the electric bill is increased, and development of the remote meter reading device capable of remote meter reading of the watt hour meter at the remote place is under development.

This remote meter reading device, that is, the remote meter reading, automates the meter reading method in which the meter reader visits the customer. That is, the electric power company uses the electronic watt-hour meter with communication function to meter the amount of electricity used in the remote place. The electronic watt-hour meter for remote meter reading has a built-in communication function, and it is a device that enables meter reading at the remote server to be performed without going to the field. Thus, the meter reading apparatus can automatically process the meter reading of the used power meter remotely by using a computer and a communication technology, without having to visit the site on a troublesome basis (see Patent Document 1).

In addition, it is equipped with a modem that can be removed and attached, which makes it easy to add maintenance and functions, and can perform remote power meter reading by various communication methods using a wireless communication system, a private line and a power line. At this time, the customer can expand the system to a system that can reduce energy voluntarily by checking the amount of power used in real time through the Internet or a display device in the home.

In order to reduce various errors generated in the above-described remote meter reading method, a method of directly reading the amount of electricity used by a customer is used. At this time, the meter reading unit does not directly record the amount of electricity, On the other hand, the presence or absence of an electronic watt-hour meter can be confirmed.

However, in the above-described method, the meter reading unit is inconvenient to carry the notebook every time the customer visits the room to check the power consumption of the customer. It is cumbersome to manage information on the results of self-diagnosis of each customer including the amount of power used by the laptop by the laptop in a database such as a power company.
