Description

TECHNICAL FIELD [0001] The present invention relates to a smart meter and a remote power control system using the SMART METER and a remote power control system using the SMART METER and REMOTE POWER CONTROL.

The present invention relates to a smart meter and a remote power control system using the smart meter.

More specifically, the present invention enables power control such as power interruption or power amount control remotely while a smart meter and a remote control center share information about a power user as a power control target.

More specifically, the present invention combines temperature, fire, and earthquake detection with an intruder monitoring function and shares the sensing and monitoring information with the control center, thereby controlling the power cutoff or the amount of power appropriately according to the situation .

In the case of apartment buildings and buildings, for example, a meter is installed separately for each room in a state in which a meter that integrally manages the electric power supplied from the electric power company is installed, and the electric power consumption is measured for each room, There are a lot of places to pay. This method has a problem of increasing the cost, such as installing a meter for each room, but it is very convenient in terms of management since it prevents the possession of a dispute about the power consumption.

However, in spite of this convenience, for example, if a legitimately charged electric power bill is not paid for a long period of time without a clear reason, it can not be enforced or the electric power can not be cut off, which makes it difficult for a manager.

In such cases, it is rare that the other residents of the building pay for the electricity bill due to reserve funds deposited in the building, which is another problem in terms of equity among the tenants.

There are many cases where not only the delinquency for electricity charges but also the use of electric heater which is prohibited for some residents are used. From the viewpoint of the manager, there is a problem of fairness due to excessive power consumption. There is another problem.

In the case of overseas, a prepayment type electric power meter is introduced. However, this system simply reads a prepaid card to supply and shut off electric power for only a charge charge, and can not perform a power control function on and off line. There is a problem that can not cope with the situation properly.

In addition, the smart meter, which has already been commercialized, has advantages such as being able to measure the power consumption remotely. However, for example, a technology capable of solving the above problems has not been developed yet.
