Description

An energy management device using a VoIP gateway as an EMS gateway, an energy management system and an energy management method {Apparatus, system and method for managing energy using internet phone terminal as BEMS gateway}

The present invention relates to energy management technology, and more particularly, to an energy management device, an energy management system, and an energy management method for managing energy use of electronic devices using a VoIP gateway as an EMS gateway.

An energy management system (EMS) is classified into a BEMS (Building EMS), a HEMS (Home EMS), a FEMS (Factory EMS), and the like according to a provision type. EMS installs sensors and measurement equipment in various electronic devices that use energy (e.g., lighting, heating and cooling facilities, ventilation facilities, outlets, PCs, home appliances, process facilities, etc.) It is a system that monitors and efficiently analyzes the collected energy use information through optimization analysis software (SW), and manages and controls the energy use of electronic devices according to the analyzed results.

The EMS has a gateway for communication of energy information between the electronic device and the EMS server. To collect energy information, the electronic device is connected to the energy sensor, the gateway receives the energy information of the electronic device from the energy sensor and transmits it to the EMS server, and receives the energy control information of the electronic device from the EMS server through the energy sensor Control the corresponding electronic device. That is, the EMS may be generally composed of a sensor, a collection device (Gateway), and an EMS server.

Here, the BEMS is configured in a building unit to provide a BEMS service, and the initial construction cost is high for such a configuration. That is, when a small office (SOHO: Small Office Home Office) resident in a building wants to receive a service, it is difficult to provide the service by configuring the BEMS system in the building.

And most of the electronic devices used in SOHO's office simply provide information using RS-485 (or RS-422) serial communication rather than IP communication. In order to collect energy information of electronic devices in the office, a gateway that handles information conversion function (serial to IP) and communication function with a server is required.

EMS gateways typically provide services on an embedded-Linux basis. To provide these services, the gateway purchase cost is excessive.

Currently, various IoT-based platforms (Home-Kit (Apple), Works with Nest/Brillo (Google), Digital Life (AT&T), Smart Home (NTT DoCoMo), ThingPlug (SKT)) have been released for Home. While EMS service is provided, there is almost no service for SOHO office, so EMS service for SOHO office is required.

Most SOHO offices use offices in complex (officetel, apartment-type factories, zone (floor, house), etc.) buildings rather than independent buildings. Unnecessary control occurs in individual offices, and it is difficult to receive essential services (air conditioning, heating, etc.) only in individual offices. In addition, in order to receive EMS service, which is essential only for individual offices, it is difficult to form a comfortable office environment through remote control or the like because it is dependent on manual control of individual offices.

- Before 9 am, the usage fee is reduced through operation during light load hours (23:00 ~ 09:00).
- Reduce energy costs by cooling (heating) the office before the temperature rises (it is more difficult to control the temperature once it rises)
- Refrain from cooling (heating) during the maximum load time (10 am to 12 o'clock) and use it for medium load (12 o'clock to 1 o'clock)
- Set and control the driving schedule in units of 24 hours a day <2. Lighting Schedule Control>
- Lights are turned off by default during lunch time (12 o'clock), and turned on manually only in necessary departments
- After work hours, all lights are turned off by time zone (6 o'clock, 8 o'clock, 9 o'clock, 10 o'clock...), and necessary departments are manually turned on

In addition, when the accumulated energy consumption power of all energy devices 2 exceeds the peak power, the energy device control unit 26 is configured in the order of the energy devices 2 according to the priority set by the EMS server 5 . A control command for cutting off energy consumption is transmitted to the energy device 2 for control. Energy consumption is limited or a power-off control command is issued for each priority energy device 2 . When the peak power is exceeded, the energy unit price is raised to a higher grade basic rate, so it is required to manage the peak power not to exceed it.

7 is a schematic flowchart of an energy management method according to an embodiment of the present invention.

First, businesses with existing VoIP gateway equipment sign up for EMS service. By service subscription, the VoIP gateway equipment of the workplace is upgraded to the energy management device 4 in which the VoIP gateway and the EMS gateway are linked.

Thereafter, the energy management device 4 receives various informational events generated from the energy device 2 and the EMS server 5 and the sensors in the workplace through wired and wireless networks (S71).

When the event is received, the energy management device 4 analyzes whether the received event is an EMS event to be sent to the EMS server or an event processed locally (S72). The EMS event is generated by the energy device 2 and includes power on/off information, energy consumption information (eg, energy usage, power factor, reactive/active power, etc.). In addition, the local processing event includes information about an abnormal situation and schedule control.

If it is analyzed as an EMS event, the energy management device 4 transmits the analyzed EMS event to the EMS server 5 (S73). The EMS server 5 classifies the received EMS event for each energy device 3, evaluates the overall energy consumption status, and generates an EMS mode or local mode control command that meets the criteria of energy policy and energy demand prediction. to give a control command for each energy device 3 . The control command is issued to the energy device 3 via the energy management device 4 and the adapter device 3 . The EMS mode means that the related event of the control command should be reported to the EMS server 5 , and the local mode means that the related event of the control command should be locally processed by the energy management device 4 .

If it is analyzed as an event of local processing, the energy management device 4 classifies the event of local processing into an event of an abnormal situation and an event of schedule control (S74).

When classified as an event of an abnormal situation, the energy management device 4 classifies the occurrence of the event into excessive energy use, long-time equipment use, and sensor/equipment error state (S751).

When the occurrence situation of the event is classified, the energy management device 4 classifies the propagation type of the occurrence situation whether it is a simple message propagation or a radio wave requiring an administrator's device control (S752).

When the propagation type of the occurrence situation is classified, the energy management device 4 inquires the manager of the energy device 2 related to the abnormal situation, and sets the inquired manager as a reception group (S753).

When the reception group is set, the energy management device 4 generates a notification message according to the propagation type, and transmits the generated message to the terminal of the reception group (S754). Here, in the case of radio waves for which the manager's device control is required, the notification message includes EMS access information, and the manager receives the notification message and links to the access information to issue a control command to the energy device 2 .

In addition, if the event is classified as a schedule control event in step S74, the energy management device 4 classifies the energy charge pattern of the event (S761). Electricity rates are classified by time period (light load, medium load, maximum load), day of the week (weekdays, weekends, holidays), and season (summer, winter, spring (autumn)). That is, a charge pattern according to unit price information of the charge of the energy device 5 in which the event has occurred is classified.

When the charge pattern is classified, the energy management device 4 generates a control command according to the schedule control in which the energy device 5 is to be operated based on the charge pattern by the equipment classification processing ( S762 ). In this process, the energy device 5 performs an operation in advance during a time when the energy rate is low, so that the energy rate and efficiency can be further optimized.

When the classification by equipment is processed, the energy management device 4 performs the processing of situation control to adjust the control command so as not to exceed the peak energy amount of each energy device 2 and the total energy device 2 (S763) ). For example, in the case of power, the basic rate of the electricity rate may be increased when the peak power is exceeded, and once the peak power is exceeded, the basic rate for one year may be increased.

Here, the energy management device 4 refers to the preset priority of the energy device 2 and uses a control command to reduce the energy consumption so that the energy consumption of the energy device 2 does not exceed the peak energy amount according to the priority. change That is, the energy management device 4 does not generate a control command according to only the schedule control, but generates a control command that meets the energy peak criterion while following the schedule control.

When the situation control is processed, the energy management device 4 performs the processing of the individual control to issue the control command generated for the event of the schedule control to the energy device 2 through the adapter device 3 (S764).

In the above-described embodiment, the term “~ unit” is not used as a term meaning hardware division of the energy management device 4 . Accordingly, a plurality of components may be integrated into one component, or one component may be divided into a plurality of components.
