The present invention may include a vibration sensor for sensing vibration information for diagnosing an abnormality of a power facility among the facilities, a current sensor for measuring a current value of the power facility among the facilities, and estimating a load capacity; An insulation resistance measurement sensor for measuring insulation resistance; For example, it is possible to divide the vibration of the power plant using the vibration sensor according to the frequency, and to detect the vibration of the power unit using the vibration sensor, such as bolt loosening, bearing failure, Can be displayed.

The reason why the insulation resistance is measured by the insulation resistance measuring sensor is to measure the leakage current of the electric equipment or the whole circuit and to prevent the accident by detecting the malfunction of the equipment or the electric shock accident when the electric leakage occurs .

In addition, an X-axis vibration signal and a Y-axis frequency signal generated in the diagnosis target motor during the operation of the diagnosis target motor among the facilities are acquired through a vibration sensor, and the X-axis and Y- 40) receives the rotation frequency of the diagnostic target motor, calculates the defect frequency from the rotation frequency, and diagnoses the fault of the motor.

For example, the energy saving module 44 can reduce energy by applying efficiency analysis algorithm based on the speed control of the power equipment among the above-mentioned equipments by a predetermined pump flow rate value.

As the efficiency analysis algorithm, a speed pattern and an optimum speed analysis of the load of the power equipment among the above equipments can be used.

It is possible to reduce the power consumption by controlling the pump by calculating the optimal speed by grasping the speed pattern of the load of the power plant by the pump flow rate value. In addition, after calculating the optimum speed, the controller informs the manager of the malfunction or malfunction of the pump by SMS or the like, and the manager manually controls the scada device 20 manually or indirectly through the server 40, So that there is no confusion.

The energy saving module 44 can reduce the energy by applying a temperature change rate efficiency analysis algorithm due to the speed control of the power plant based on a predetermined air conditioner airflow value.

The temperature change rate efficiency analysis algorithm measures the degree of temperature change corresponding to the air conditioner air volume value and not directly increases or decreases the air conditioner air quantity value in the case of the sudden decrease or surge of the temperature change rate, The power plant is operated with an average air volume value based on the air-conditioner air-volume value per hour, and an alarm is transmitted to the managers.

In other words, energy can be saved by analyzing the speed pattern and optimum speed of the air conditioner according to the time of each building load, and it is possible to maintain the constant value by referring to the existing information even when the temperature measurement sensor or the air conditioner fails.

The energy saving module 44 stores an amount of usage of the air conditioning system in accordance with a temperature change of the weather, indoor or outdoor temperature, and a holiday according to time, and then uses an algorithm that can save energy by predicting the amount of use of the air conditioning system in advance .

For example, if the present room temperature is higher than the lowest temperature stored in the DB and is lower than the best temperature as a result of comparison between the temperature changes of the weekday and the holiday, the fan speed is fixed at a constant value without adjusting the valve of the air conditioning system, You can write an algorithm so that there is no energy consumption.

In addition, the server 40 receives design data of various equipments of buildings or buildings in advance and stores energy demand amount, energy consumption amount, CO2 emission amount, and new and renewable energy production amount. The optimum control information can be calculated.
