Description

Electronic watt-hour meter and automatic meter reading system with remote power interception and controller

The present invention relates to an electronic electricity meter and a remote meter reading system that can quickly and remotely cut off and control power in the event of emergency or non-payment of electricity.

In general, an automatic meter reading system (AMR) refers to converting a measurement result into an electrical signal from a measurement object at a distant point, transmitting data through a communication network, and processing the data in a computer.

The remote meter reading system is a system for automatically processing the meter reading by remotely using a computer and communication technology without the need for a meter reading visitor, and acquires the weighing data with a data collection device, and the information is a communication processing device It is a fully automated system that sends a series of processes to the weighing server via the front end processor (FEP). In addition, the metering information of each customer transmitted is linked to the customer number through the data processing process in the metering server, calculate the time / day / month usage is provided as data for service billing, settlement, guidance.

The communication between the FEP and the data collection device uses a mobile communication network and a hybrid fiber coax (HFC), and the remote metering server can be connected to other systems in KEPCO. The data collection device can be designed with an extended concept to enable the integrated reading of water, gas, and heat in the future.

The remote meter reading system receives the meter reading data of each consumer in real time from the data collection device, and analyzes the idle state, the challenge, the leakage state, and the like, which can know the power state of each consumer based on the data, and provides it to the manager.

According to the related art, since the remote meter reading system includes a simple meter reading function without a power cut function, when the operator wants to cut off the power arbitrarily, the remote meter reading system requires a long time to shut down the power as the power meter needs to be visited and operated. .

Therefore, when emergency power cuts are required due to natural disasters such as fire and non-payment, there is a demand for a method of quickly shutting down power without directly visiting the operator.

The present invention includes a remote power cut-off and control function that can cut off and control power remotely in case of emergency and occurrence of charge by installing a power cut-off relay inside or outside the electronic wattmeter to solve the inconvenience of the prior art. The purpose is to provide an electronic electricity meter and a remote meter reading system.

In the electronic wattmeter and remote meter reading system including a remote power cut and control function of the present invention to achieve the above object, it is possible to cut off and control the power of each customer from a remote using a power cut relay.

The present invention relates to an electronic electricity meter including a remote power cut-off and control function, and includes a power control unit for remotely turning on or off a power supply by a power-off command of a server for higher remote meter reading (AMR), and a power cut-off relay It is preferable to include.

In the present invention, the power cutoff relay is preferably installed in the electronic wattmeter or detachable.

The present invention relates to a remote meter reading (AMR) system including a remote power cut-off and control function, through an electronic meter and a meter reading data obtained through a data collection device It is preferable to include a server for a higher remote meter reading (AMR) to determine whether the electronic electricity meter is shut off, and to control the power of the electronic electricity meter through wired or wireless communication.

According to the present invention, in the event of an unpaid charge or an emergency situation such as a fire or a natural disaster, the power can be quickly dealt with by remotely shutting off the power, thereby preventing secondary damage such as an electric short circuit.

In addition, there is an effect that can quickly and remotely cut off and control the power of the customer is a challenge and a short circuit occurs.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In adding reference numerals to the components of the following drawings, it is determined that the same components as possible, even if displayed on the other drawings as possible, and unnecessarily obscure the subject matter of the present invention Detailed descriptions of well-known functions and configurations will be omitted.

1 is a view showing a remote meter reading system including a remote power off function according to an embodiment of the present invention.

Referring to FIG. 1, an electronic power meter 100, a data collection device 110, and a server 120 for a higher remote meter reading (AMR) are included.

Each of the electronic wattmeters 100 is installed in the customer, and the power amount used by the customer is read (current and voltage monitoring), and the metered data is transmitted to the data collection device 110 using a PLC or an RF modem. At this time, the present invention includes a power control unit 102 and a power cut-off relay 104 to receive and execute a power cutoff signal remotely to the electronic electricity meter (100).

In the conventional induction-type and electronic electricity meters, when the operator wants to cut off the power, such as a failure of the electricity meter and an error in the meter reading data, the operator directly visits the customer to cut off the power. The power control unit 102 and the power cutoff relay 104 of the electronic electricity meter 100 may remotely cut off power.

In addition, it is possible to remotely block and control the power supply through the power control unit 102 and the power cut-off relay 104 of the electronic watt-hour meter 100, whereby when the situation such as unpaid charges and natural disasters occur, By remotely shutting off the supply, secondary damage such as an electrical short can be reduced. In addition, it is possible to remotely quickly cut off the power of a customer who has incidentally caused a short circuit.

In addition, the power cutoff relay 104 may be integrally installed inside the electronic wattmeter 100, and may be detachably installed outside the electronic wattmeter 100 when the internal space is insufficient.

The data collecting device 110 collects a plurality of meter reading data generated by the electronic electricity meter 100 installed in each customer by using power line communication (PLC) or wireless communication (RF) method, and the optical coaxial mixed network ( HFC) or Coat Division Multiple Access (CDMA) network can be used to transmit to the server 120 for higher remote meter reading (AMR).

In addition, the power cut-off relay 104 may be a 220V relay when using a single-phase electronic electricity meter, and 220 / 380V for each of A, B, and C phases when using a three-phase electronic electricity meter. Relays may be used (see FIGS. 2A and 2B).

The upper remote meter reading (AMR) server 120 communicates with a plurality of data collection devices 110 by wired / wireless to acquire meter reading data, and the electronic power meter 100 via the data collection device 110. ) Can be controlled.

In particular, in the present invention, since the operator can directly cut off and control the power of the electronic electricity meter 100 through the data collection device 110 in the upper remote meter reading (AMR) server 120, in case of emergency By quickly shutting down and controlling the power supply without visiting, it can reduce secondary damage such as an electrical short.
