It is possible to optimize the replacement timing by using an algorithm that can propose replacement of the pump, air conditioner, lighting, refrigerator, and boiler equipment by comparing energy consumption patterns.

Meanwhile, the present invention can enhance the VPN-based security, and the VPN can be used. The VPN is a solution for enabling a VPN connection regardless of the place where an Internet connection is possible. It is a VPN-based protocol developed to overcome the disadvantage that the existing Internet protocol can not maintain confidentiality by improving the productivity and work efficiency of enterprises by providing mobility.

A remote access (VPN) system is a virtual private network (VPN) that enables access to major Scada servers from the outside Internet and ensures safe data transmission from various security problems that may occur when connecting to the outside world.

The present invention separately manages individual pump, air conditioner, lighting, refrigerator, and boiler parts with serial numbers, and when it is replaced, it resets the cumulative recording data and replaces the recorded data of the replaced part with the proper Show the replacement time and display the parts that have come to the replacement time on the monitor screen of the monitoring system, or send it to the manager or mobile.

Therefore, there is an effect that it is possible to display and replace the corresponding parts as replacement at an appropriate replacement time before the life expectancy reaches. Also, by collecting data from each organization in the ground center system, parts that are nearing the exchange time can be prepared in advance, so that the operation of the facility can be prevented from being affected.

Further, the present invention can monitor and display the abnormality of each facility (pump, air conditioner, lighting, refrigerator, boiler) based on the API map.

As shown in FIG. 4, the present invention integrally manages the processes described below via the at least one of the scada 30 and the server 40 or the EMS server and the central server.

First, various sensor information is acquired (S101).

And confirms whether the sensor information is repeated. If the sensor information is not repeated, it becomes difficult to obtain a certain pattern. Therefore, the sensor information is repeatedly obtained until a repeated pattern appears (S102).

When the repetitive pattern occurs, predetermined pattern information is acquired (S103).

It is checked whether the predetermined pattern information is repeated for a period in which analysis is possible.

The analyzed information is analyzed for each time of generation (S104, S105, S106).

Time-based prediction information is generated (S107).

In addition, current sensor information is acquired (S108). This is to judge whether past prediction information is similar to current sensor information and to apply it.

And generates and transmits optimal operation / control information according to the determination information (S109).

Energy saving information according to the optimum operation / control information is displayed (S110). At this time, the current sensor information is referenced to determine how much the previous sensor information is saved.

Referring to FIG. 5, a server and a Scada EMS-based energy saving and management method according to an embodiment of the present invention will be described in detail.

Various sensor information is acquired, and it is confirmed whether the sensor information is repeated (S201, S202).

And acquires predetermined pattern information (S203).

It is confirmed whether it is a period that can be analyzed (S204).

The analysis information for the period is classified for each facility and divided into analysis information for each facility (S205, S206).

And generates facility-specific replacement prediction information according to the analysis information (S207).

It is judged whether or not the facility-specific parts replacement time has come (S208).

And transmits replacement information according to the determination information to the manager (S209).

Meanwhile, as shown in FIG. 6, the server and the Scada EMS-based energy saving and management system according to the present invention acquires each renewable energy efficiency information (S301).

When the acquisition of each new renewable energy efficiency information is completed, an energy saving rate is calculated (S302, S303).

When the energy saving rate calculation is completed, the convergence energy saving efficiency is analyzed (S304, S305). Then, the total energy saving information is displayed (S306).

As shown in FIG. 7, the present invention is applied to an illumination facility as an embodiment of the present invention. Each control step to be described later is performed around the EMS server 40.

The EMS server 40 divides the area in which the lighting equipment is installed according to a certain criterion, measures the illuminance in each zone, and performs a data processing process in which the illuminance is constant in all the zones.

Thus, lighting equipment can be divided into lighting areas (for example, areas A, B, and C based on the window), and uniform lighting can be maintained through differential lighting control to reduce energy while lowering eye fatigue.

In other words, the higher the illuminance of a window is, and the lower the illuminance becomes, the more the illuminance is decreased. By differentiated lighting control, This has the advantage of softening.

For example, the window zone (zone A) is illuminated by daylight at daytime, and the closer the zone is to window (zone C), the lower the illumination level.

First, illuminance data according to time is divided into illumination zones and collected (S401).

The illumination data is extracted from the stored information of brightness of the internal equipment with reference to the previous year's time (corresponding date and time).

If the illuminance data is less than or equal to a constant value in any lighting zone, the brightness of the lighting fixture is reduced (S402, S404).

If the illuminance data is equal to or greater than a predetermined value in any lighting zone, the brightness of the lighting fixture is increased (S403, S405).

Subsequently, the illuminance sensor information is obtained by dividing the illuminance sensor information by illuminated areas, thereby raising the brightness of the illuminating equipment in the illuminated area where the sensor information is equal to or less than a predetermined value (S406, S407, S408).

However, if the sensor information of the illumination zone is equal to or greater than a predetermined value, the brightness of the lighting apparatus is maintained or decreased (S409).

As shown in FIG. 8, when the present invention is applied to a boiler according to an embodiment of the present invention, the degree of coldness (room temperature) with time is calculated (S501).

If the temperature information is not more than a predetermined value, the boiler facility is operated (S502, S504).

If the temperature information is equal to or greater than a predetermined value, the boiler facility is turned OFF (S503, S505).

Subsequently, the room temperature sensor information is acquired and it is confirmed whether or not the sensor information is a predetermined value or less (20 degrees) (S506, S507).

At this time, if the sensor information is less than 20 degrees, the boiler facility temperature is raised (S508).

However, if the sensor information is more than 20 degrees, the boiler facility temperature is maintained (S509).

In addition, the above-described control method can be applied to a refrigerator or various temperature-related equipment.

As shown in FIG. 9, when the present invention is applied to an air conditioner as an embodiment of the present invention, the degree of coldness (room temperature) with time is calculated (S601).

If the room temperature information is equal to or less than a predetermined value, the air conditioner equipment is operated (S602, S604).

If the temperature information is equal to or more than a predetermined value, the air conditioner equipment is turned OFF (S603, S605).

Additional fine dust sensor information is acquired while the air conditioner is operating (S606).

If the sensor information is equal to or greater than a predetermined value, the air conditioner motor speed is increased (S607, S608).

However, if the sensor information is less than a predetermined value, the air conditioner motor speed is maintained (S609).
