Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an Internet-based wireless power management system having a scheduling function,

The present invention relates to an Internet-based wireless power management system having a scheduling function and a method thereof, and more particularly, to an Internet-based wireless power management system and method capable of selectively supplying and blocking power to electric and electronic devices in a building, Based wireless power management system having a scheduling function and a method thereof.

Regarding the device for preventing energy saving and blackout, there are a large number of registered and disclosed devices in addition to Korean Patent No. 10-1301704 (hereinafter referred to as "precedent document").

The above prior art document discloses a plug type power line connection terminal detachably connected to the end of a power line which is a socket type and receives power, A main body having a receptacle type load power line connection terminal connected to a power line connection terminal via one end of the controller power line and detachably connected to the end of the load power line drawn out from the demand control target device, A frequency sensor installed in the main body and sensing a frequency of electricity supplied through the power line; A current sensor installed in the main body and sensing a current flow; A temperature sensor installed in the main body, for sensing an indoor temperature of a place where the demand control target device is installed; And a control unit which is installed in the main body, reads a frequency sensed by the frequency sensing sensor, outputs a switching signal according to the read frequency value, receives a current sensing signal from the current sensor, A control unit for outputting a switching signal according to a room temperature value from the temperature sensor; A switching unit installed in the main body and switching power supply to the demand control target device according to a switching signal from the control unit; .

 On the other hand, if the amount of electricity used is larger than the electricity generation momentarily, a large-scale blackout phenomenon is expected. When the amount of electricity used is increased close to the amount of power generation, the voltage starts to fall due to excessive supply current in the generator. Turbines connected to the generator also begin to increase the supplied steam pressure.

If the voltage drops and the overcurrent flows, there is a fuse or a breaker to stop the generator to protect the generator. However, if the generator is stopped, the generator can not be stopped because the generator is overloaded. I will write down how to stop.

If there is no precipitation in a certain area, it will take a long time to recover the power plant due to other problems such as breakdown of the power plant breaker or damage to the generator. Occurs. Therefore, when there is a possibility of a surge in power consumption, the maintenance and maintenance of the power plant are suspended and the private power plant is also awaited.

A detailed look at the domestic blackout countermeasures shows that power alarms are classified into five levels based on reserve power. If an emergency occurs in the supply and demand of electricity, emergency measures are declared and emergency measures are taken according to emergency manuals.

In the first stage (preparatory), where the reserve power is less than 5 million kW, the company instructs the generator to operate, and in the second stage (attention) of less than 4 million kW, the primary voltage is downwardly adjusted. Reducing the secondary voltage and stopping the power supply to the pre-contracted companies. Emergency power saving of the industrial core process facilities in the 4th stage (boundary) of 2 million kW or less. Finally, in the 5th stage (serious) Perform a downtime. On August 6, 2012, the Korea Power Exchange (KPX) issued a warning for the first time since '9.15 blackout' in 2011 due to surging power supply due to the longest heat wave ever.

This is because electricity supply and demand imbalances have become more frequent in recent years because everything has become mechanized and automated, making clean and convenient electricity use more common, and the amount of electricity used has increased sharply because electricity has been supplied at a low cost below production cost.

In this way, people's desire for power consumption grows, but it is quite difficult to construct a power plant to increase its supply. First of all, various environmental groups are opposed to environmental destruction because they are trying to build a power plant.

First, the research trends at home and abroad will be examined. First, developed countries such as the US and Japan are implementing national programs to develop and promote strong policies for energy efficiency. The United States (Building America) aims at realizing the implementation and dissemination of energy-efficient buildings using state-of-the-art technology, and developing national projects aimed at fostering energy-efficient products, The Department of Energy (DOE) is being implemented largely in connection with housing construction companies. For example, the New York Times building in the United States uses Lutron's Quantum solution to achieve 30% daylight savings, 10% human detection, 2% schedule control, and 58% illumination reduction by applying an integrated lighting management system.

Meanwhile, Canada (R-2000 program) is running the national program for product, design, construction and dissemination throughout the country with the aim of promoting energy-efficient housing. It is also involved in the construction of pilot houses, public information, And the implementation of the

Japan (Home Value Innovation Project) started with House 55 in 1975 and led a national project to lead the housing technology market of about 5-6 years, including House Japan and resource circulation housing technology development project, It has been in operation for 40 years. Japan is investing in the establishment of the "Cool Earth - Energy Innovation Technology Plan" under the goal of reducing the world's total greenhouse gas emissions by half by 2050. The Panasonic Electric Building's Emitotal Building System was developed in 2002 based on research results that demonstrate the "30% reduction in office building power consumption" in the joint research between Panasonic Electric Works and the New Energy Industrial Technology Development Organization (NEDO) Saving building system.

Features of the Emito total building system include total energy saving control of buildings including lighting control / air conditioning control / energy data measurement / measurement. It is also a remote energy saving control system based on WEB.

There are various methods for the energy efficiency of buildings in Korea. However, there are only simple control functions such as ON / OFF, current temperature and humidity monitoring, change of control value setting, reservation operation, Control systems, sensors, and control devices are largely dependent on imports, making control / arithmetic algorithms unsuitable for Korea.

Focusing on LS Industrial Systems, the Ministry of Knowledge and Economy is developing AMI (Advanced Metering Infrastructure) technology focusing on the Smart Grid project. It plans to apply it mainly to home automation and large-scale industries. On the other hand, we are introducing and operating a building energy management system (BEMS, Building Energy Management System) mainly for large buildings such as the Trade Center, Samsung C & T, and some new government buildings. However, Air conditioning, lighting, sanitation, disaster prevention, etc. However, in reality, only electricity is managed. BEMS has been installed in Samsung C & T's headquarters building to receive Japanese technology, but so far it has collected operational information, performance information, and energy usage for various devices and processed it statistically. It is not included. Although we are in the process of establishing eco-friendly and energy-related certification plans and eco-friendly architectural plans, they are yet to be fully implemented.

The goal of the present invention is to reduce electric energy by cutting off electric power in homes and buildings. The necessary research for this is as follows.

First, we analyze how much standby power is consumed in various electric and electronic devices in home or building and analyze how much energy can be saved if it is properly shut off using power cutoff terminal.

Second, since electric and electronic devices such as building vending machines and cold / hot water appliances are not used on weekends or late at night or at dawn, energy savings can be obtained when a scheduling technology that cuts off power through a power cutoff terminal at this time .

Third, in case of unavoidable situations such as a large-scale power outage, the result of analyzing the result is implemented by simulating the function of selectively interrupting the electric power of the non-urgent electric and electronic equipments except for the elevators and emergency lights.

As described above, there is a continuing demand for a user-oriented "monitoring and control technology for building energy efficiency" in order to change the perception of domestic and overseas environmental problems and improve the inefficient use of energy in our country It is urgent to localize the technology that is highly dependent on overseas technology.

Therefore, significant energy savings will be achieved if the standby power of various electric and electronic devices in the home or building is appropriately blocked using a smart tag. In addition, since electrical and electronic devices such as building vending machines and cold / hot water appliances are not used on weekends or late at night or at dawn, energy savings can be achieved by adopting a scheduling technique that cuts off power through smart tags during this time It is significant.

In the unavoidable case such as a large power outage, it can be a great help to prevent the national blackout when the function of selectively blocking the electric power of the non-urgent electric and electronic devices except for the elevator and the emergency light, which is essential, is introduced.

By demonstrating the savings on building energy savings, it will raise public interest in and encourage the use of energy saving, thereby increasing the necessity of securing technology for national energy saving and ultimately leading to user-oriented energy saving, Effect can be expected.
