A warning message may be exposed together, and the storage unit 300 may be accompanied by a reference message stating 'Error details were confirmed in a total of 5 facilities this month'. In addition, the message may be determined whether to expose the message to each sub button by checking whether the guide message is provided in the setting guide unit 212 .

Meanwhile, in the customer information, the customer's phone number is hidden behind the customer name, and when a desired customer name button is clicked, a balloon based on the expansion window is exposed and the hidden phone number can be checked. In addition, as for the number of reception information, if data is received more than 5 times a day, there is no problem in identifying the equipment through monitoring, and it is recommended to set the reset at 12:00 midnight every day. If the number of receptions is less than 5, the hearing loss area is registered as a hearing loss area in the hub meme and may be used as a basis for requesting an extension of the gateway. As for the facility error information, when you click the code number to which the error guide display is assigned, detailed information about the cause of the error can be checked as the rich language is exposed. may be exposed.

The list unit 220 provides a smart search and new registration management service in which a renewable energy source, an address where a facility is installed, an installed facility code, a type of facility and a customer name are separated by category.

First, the renewable energy source provides primary classification categories such as solar heat, wind power, hydraulic power, and electric power, and in the case of solar heat, secondary classification categories such as solar single phase, solar three phase, solar forced, solar thermal nature, geothermal energy, etc. and provides the option to select the energy source of the facility address.

If desired, the search results can be converted into an Excel file to provide information or print.

The sensing unit 230 not only detects operating errors of the platform 1 and the facility, but also detects the weather and climate of the area where the facility is installed in real time, and can be used as reference data such as predicting or deriving the amount of power generation and production of renewable energy. It plays a role in collecting information.

To systematically perform this, the sensing unit 230 detects program errors and device errors of the facility based on the weather observation unit 231, which manages weather and climate observation and the observed information, and the communication modem and CCTV link around the facility. It consists of an error detection unit 232 that is sensed in real time, and an energy analysis unit 233 that statistically analyzes the amount of generation and production of renewable energy within a set period.

The weather observation unit 231 includes sunrise, solstice, sunset, day length, uniform time difference, declination, morning and evening citizen/sea/astronomical twilight, current solar azimuth, and current solar elevation in the area or vicinity of the facility installed. , climax angle, precipitation pattern, temperature, humidity, wind speed, ultra-fine dust, fine dust, etc. are observed in real time, and the observed information is classified by item and then stored and stored in a separate state.

The error detection unit 232 detects D-EUI error detection, equipment error detection, and equipment code error based on the RTU function, and exposes the detected content to the display or transmits a message to the terminal registered by the operator. The error information message conveys the details of the failure, facility address, type of power generation, customer information, and the time of the error occurrence. may be

For example, the facility error is a value that the facility controller sends the facility status to the RTU as a code through communication. You can also check the hidden phone number as it is exposed.

The energy analysis unit 233 measures the amount of generation of renewable energy only for facilities whose normal operation has been proven under the judgment of the error detection unit 232 , and calculates the average climate within the measurement period using the measured generation information to determine the climate of the region Relevant big data is automatically generated.

On the other hand, the energy analysis unit 233 includes detailed functions such as detection of inspection errors, control of the incident angle, azimuth, and inclination angle of the panel, previous day's power generation management, today's power generation amount management, total generation amount management, facility measurement value management, installation longitude and latitude management, accumulated generation amount Error value management, accumulated power generation reception time management, today's reference value management, accumulated power generation correction value management, facility reset and self-diagnosis control and management are provided.

In the energy analysis unit 233 , the inspection error detection function manages errors detected by the server program analyzing data, and the panel incident angle, azimuth, and inclination angle control functions control the panel incident, azimuth, and inclination angles of the corresponding equipment. and, the previous day's generation management function guides the generation of the previous day based on the date displayed in the cumulative generation reception time, and the today's generation management function guides the generation of the current day based on the day displayed in the cumulative generation reception time, and the total The generation amount management function guides the accumulated generation amount of the date indicated in the cumulative generation amount reception time, the cumulative generation amount error value management function guides the error accumulated generation amount at the time when the inspection error occurs, and the cumulative generation amount reception time management function provides the inspection error guides the last time that data of normal accumulated power generation without communication energy is received The adjustment value (Wh) guides the increase/decrease time value, and the reset and self-diagnosis control and management functions of the equipment restart the equipment with the reset button or self-diagnose the equipment with the self-diagnosis button.

For example, the inspection error detection function displays error codes such as a decrease in the accumulated power generation and a power generation threshold error (a power generation greater than the installed capacity). On the other hand, 0 among the displayed values is normal, and if you click the code when other numbers appear, the content of the error is exposed in a balloon.

The panel incident angle calculates the altitude and orientation of the sun in real time based on information on the installation longitude, installation latitude, panel azimuth, and panel inclination angle, and finally provides the incident angle of the corresponding facility as a numerical value. The incident angle is an important factor for energy production, and the amount of energy produced is increased during a time period when the incident angle is decreased. Since the angle of incidence can act as an important factor in statistical analysis of power generation with other facilities, it is desirable to input the correct installation longitude, installation latitude, panel azimuth, and panel inclination angle when registering the facility.

The accumulated power generation error value Wh is configured so that when a check error such as a threshold error occurs when the accumulated power generation decreases, it is easily known why the check error occurred by comparing the value with the previous normal accumulated power generation amount.

The accumulated power generation reception time is different from the last time data was received regardless of any errors, and represents the numerical values based on the previous day's power generation amount, today's power generation amount, total power generation amount, and the accumulated power generation amount reception time standard.

The accumulated power generation correction value is preferably in consideration of the existing accumulated power generation and numerical values in order to calculate the accurate generation amount statistics if the controller or inverter of the facility is replaced or if there is a situation in which the accumulated power generation is converted and transmitted for some reason. The accumulated power generation correction value is corrected in the hub meme server, and when the hub meme manager finds an abnormality, the hub meme manager contacts the relevant company to check the condition of the facility and then recommends correction.

The processing unit 300 prioritizes non-face-to-face primary cause treatment using monitoring based on the operation information of the facility detected by the management unit 200 and the climate information measured from the surroundings of the facility, and the first If the cause is not resolved even after the cause is dealt with, the cause information is transferred to the on-site worker so that the on-site self-treatment is recommended.

Facility maintenance and repair using the platform 1 of the present invention configured as described above is performed in the following procedure, for example, the new and renewable energy facility is solar power, solar heat, geothermal, wind power, fuel cell, ESS, etc. can be given as an example.

3) Reset the control unit, RTU and communication modem primarily through remote control.

4) Secondary through remote control, self-diagnosis operation of the control unit, RTU and communication modem, and then check the status.

5) Recommend offline on-site A/S after reassessing the operating status of equipment through remote control.

6) Result Reporter is issued after A/S is completed.

When the controller of the field facility recognizes the error of the facility and determines the clear cause of the error through self-diagnosis

[Features]: Accurate error status can be identified. Determination of equipment error in monitoring program

- Error example: A00131F72605DA185331 (Leak current occurred)

Accurately recognizes errors in the controller, inverter, and heat pump control device, and transmits error information to the RTU connected to the RS-485 communication line with the cause of the error.

- Actions

1) Control device reset → Self-diagnosis program execution → Control device error judgment

2) RTU reset → Self-diagnosis program execution → RTU error judgment

If the error is not resolved after taking action, on-site A/S recommendation to respond to the error result

When the facility has only RTU information and does not send power generation and facility data information

[Features]: Only RTU information, no information on energy facilities. Determination of equipment standby status in monitoring program

- Error Example: A0011

No data is transmitted through communication from the controller, inverter, or control device of the heat pump. Since the RTU holds its own information, it is more likely to be normal.

- Equipment status due to errors

1) Equipment failure

2) Shut off equipment power

3) In case of solar power, inverter system power is used to supply power to RTU, and if there is no harm, RTU power is cut off and does not work.

- Actions

1) Control device reset → Self-diagnosis program execution → Control device error judgment

2) RTU reset → Self-diagnosis program execution → RTU error judgment

- result

Recommendation for on-site A/S because the equipment is in a malfunctioning state or there is a power supply problem

If the equipment does not have data information

[Features]: All information is missing. Determination of equipment standby status in monitoring program

- Error example: Data is not transmitted through communication between the RTU and the controller, the inverter, and the control unit of the heat pump.

In case the data information is not fixed in the facility

[Features]: There is information, but the data format and number of digits are variable. Determination of facility warning status by monitoring program

- Error example: 12:00 A00131F72605DA185351, 12:30 A00131F7, 13:00 A00131F72605D

Variation of the number of data digits in the facility information causes noise in the communication line between the control unit and the RTU, making accurate data transmission impossible.

- Equipment status due to errors

1) Accurate data collection impossible due to noise

2) Normal communication occurs intermittently when equipment does not generate power

- Actions

1) Control device reset → Self-diagnosis program execution → Control device error judgment

2) RTU reset → Self-diagnosis program execution → RTU error judgment

Since noise gathers in weak places, we recommend A/S at the RTU stage and communication line

Normal communication occurs intermittently when equipment does not generate electricity

monitoring on the server big data When an error is judged by analysis, and the accumulated amount of power is kept constant even if the cause of the error is over time

[Features]: Although the general equipment is in a normal state, if the data is analyzed, A/S processing is recommended because the control unit is malfunctioning and the RTU is malfunctioning. The monitoring program determines that the equipment is in a normal state

- Error example: A00131F72605DA185330

Data is normal, but there is no change in data or no change in accumulated power generation after 3 hours.

- Equipment status due to errors

1) Communication line signal latch status due to noise

- Actions

1) Control device reset → Self-diagnosis program execution → Control device error judgment

2) RTU reset → Self-diagnosis program execution → RTU error judgment

- result

Normal operation possible

If the same error occurs frequently even after normal operation, noise countermeasures are recommended to field facilities

When normal data and overvoltage data coexist in one day

[Features]: Although the general equipment is in a normal state, it is recommended to handle A/S because the efficiency is low when data is analyzed. The monitoring program determines that the equipment is in a normal state

- Error example: 12:00 A00131F72605DA185351, 12:30 A00131F72605DA185330, 13:00 A00131F72605DA185351

Inverter problem with low power generation efficiency when 3 or more overvoltage data are generated continuously in one day's power generation data. Comparing the amount of power generation under similar ambient conditions, when the power generation is less than 90% In case of AND condition with the above conditions

- Equipment status due to errors

1) Inverter status error

- Actions

Inverter A/S recommendation due to inverter internal problem

Treatment of power generation facilities where the power generation status of the facility is normal but the power generation efficiency is inferior compared to the conditions of the surrounding power plant

[Features]: The power generation status is normal, and the efficiency is less than 90% of the normal facility, so warning processing is required. The monitoring program determines that the equipment is in a normal state

- Error example: When the current generation of a facility is 8kW and the current generation of nearby facilities is 10kW

[variable data]

1) Calculating the angle of incidence of the sun to determine and predict power generation efficiency

* Integer value: installed panel latitude, longitude, inclination angle, installation direction

* Variable value: position of the sun

* Calculated value: Calculates the angle of incidence of the sun with integer and variable values

* Applied value: The closer the angle of incidence of the sun is to 0 degrees, the greater the power generation efficiency.

2) Weather information Access the public data server and read the weather information of the current time and location to understand and predict power generation efficiency

3) Reading power generation data from the control device to understand and predict power generation efficiency

- Equipment status due to errors and measures to be taken

1) Inverter status error → Inverter A/S recommendation due to inverter internal problem

2) Equipment leakage current → Check the equipment power line and determine the state of leakage

3) Decrease in power generation efficiency of equipment → Review replacement due to reduced efficiency of inverter and panel
