Description

Intelligent outlet for power consumption pattern analysis system {SMART RECEPTACLE FOR CONSUMPTION POWER PATTERN ANALYZING SYSTEM}

The present invention relates to an intelligent outlet for a power consumption pattern analysis system, and more particularly, to collect and store power consumption from one or more intelligent outlets installed in individual consumers, and to display the collected power consumption monthly or real time, as well as carbon dioxide. In addition, the power consumption pattern analysis system and wired / wireless communication network can reduce power consumption and monitor power consumption by displaying standby power consumption and displaying standby power consumption and monitoring standby power automatically or manually. The present invention relates to an intelligent outlet for a power consumption pattern analysis system used in connection.

Currently, various kinds of electronic products such as TVs, refrigerators, computers, printers, and copiers are generally used in each home or office.

Most users use various electronic devices connected to the outlets, and there is a problem that the so-called standby power is consumed, which consumes a large amount of electricity even when the electronic products are not in the standby state. Can save.

However, in the related art, since a device for easily shutting off standby power has not been provided, the standby power cutoff of the electronic product has to be relied on by the user unplugging the battery. Due to the hassle of unplugging, there was a problem that the standby power blocking is not widely executed.

On the other hand, the ultimate goal of efficient building energy management is to minimize the use of energy consumed for indoor environment control such as cooling / heating, ventilation, and lighting without compromising the comfort of living spaces.

Even if technical measures are taken to conserve energy in a building, the effect cannot be expected without close and continuous energy management of actual building energy use, system efficiency, normal operation and operation schedule.

Therefore, in advanced countries, separate building energy managers are assigned to thoroughly manage the energy consumption level and operation status of the building, so that the building is always operated with the best energy efficiency.

In addition, we are focusing on the continuous development of technologies in terms of energy consumption analysis and diagnosis of abnormality of the system according to the unique thermal characteristics of the building.

On the other hand, in recent years, the United Nations Climate Change Convention has strengthened the obligation to reduce greenhouse gases by country, and once Korea joins the Organization for Economic Cooperation and Development (OECD), it is difficult to avoid the pressure to reduce the obligations of advanced countries.

As a result, it is urgent to develop clean energy that can minimize greenhouse gas emissions and foster environmentally friendly industries, and building is a burden factor that weakens the competitiveness of a company unless it is an energy-saving building that emits less greenhouse gas.

Therefore, in order to manage efficient building energy, it is necessary to accurately monitor the electricity use devices in the building.

However, the existing remote meter reading system is made for the purpose of monthly billing and cannot perform the energy management function. That is, since the meter is installed for each billing subject in the building, the power consumption broken down by load is not known and is not real time and is unidirectional.

In addition, most of them use simple non-standard technology and manufacturer's dedicated communication protocol, so it is impossible to be compatible with and expand functions, and it is impossible to provide information on power consumption of general users by monitoring and controlling and managing specified energy-related devices.

As a technology for solving such a problem, a smart energy management system and method of a building have been disclosed (Korean Patent No. 10-0963161, registered on June 4, 2010).

However, the technology does not meet the needs of users who want to know the power consumption patterns individually by analyzing the power consumption patterns in the electronic devices connected to individual outlets in the energy management aspects.

The present invention has been proposed to improve the above-mentioned problems, and collects and stores power consumption from one or more intelligent outlets installed in individual customers and displays the collected power consumption monthly or real time, as well as carbon dioxide generation amount. In addition, it also displays the standby power consumption and monitors the standby power to cut off the standby power automatically or manually to reduce the power consumption and to monitor the power consumption by providing an intelligent outlet for power consumption pattern analysis system. have.
Another object of the present invention is to apply a control signal to the switch driver to cut off the first switch or the second switch according to the comparison signal of the measurement value storage / comparison unit, the current measurement result of the comparison result of the measurement value storage / comparison unit When there is no numerical change between the value and the previous measured value stored in the memory, it is determined whether a certain time has elapsed, and when a certain time has elapsed, a control signal is applied to the switch driver to turn off the first and second switches to supply the constant power. By applying a control signal to block the current, the standby power can be effectively cut off even when unused electronic devices are connected to the outlet. It is to provide an intelligent outlet for power pattern analysis system.

According to a preferred embodiment of the present invention for achieving the above object,

The communication unit can be either RS485 or IrDA or Zigbee devices. However, it is not limited thereto.

With reference to Figure 7 looks at the operation of the intelligent outlet for power consumption pattern analysis system according to the present invention.

First, the central control unit 110 determines whether user data of an IrDA or Zigbee communication port is input (S1).

As a result of the determination of step S1, when user data is not input, the user measuring unit 130 reads and stores the usage value from the sensor unit 120 (S3).

Then, the measurement value storage / comparison unit 112 of the central control unit 110 compares the current measurement value and the previous measurement value in the memory to check whether there is a numerical change (S5).

In step S5, if there is no numerical change (S7), it is determined whether a predetermined time has elapsed (S8), and if a predetermined time has elapsed, the central controller 110 switches because it is a standby power state of the load. A control signal is applied to the driver 150 to turn off the first and second switches 160 and 170 to cut off the power supply at all times (S9). Subsequently, standby power is cut off in response to the first and second switches 160 and 170 turned off (S10).

In the step S7, when there is a numerical change, since the user is using the electronic electrical appliance connected to the outlet of the indoor wall, the central control unit 110 periodically reads the value of the usage measuring unit 130 and stores it in the memory ( S11).

Thereafter, the central control unit 110 determines whether there is input data from the 485 communication port (S13). If there is input data in step S13, the central control unit 110 interprets an external control command (S15), and determines whether there is a power consumption value transfer command from an external server (not shown) (S18). .

If there is a power consumption value transfer command in step S18, the central control unit 110 reads the stored value from the memory and transmits it to the RS485 communication unit, that is, the communication unit 140 (S19).

If there is no power consumption value transfer command in step S18, it is determined whether there is a switch off command from the user (S20). In step S20, when there is a switch off command from the user, the central controller 110 applies a control signal to the switch driver 150 to turn off the first and second switches 160 and 170. (S21).

If there is no switch off command from the user in step S20, it is determined whether there is a switch on command (S22). In step S22, when there is a switch on command from the user, the central controller 110 applies a control signal to the switch driver 150 to turn on the first and second switches 160 and 170.
