In detail, the light quantity guide module 320 includes an input unit 321, a test unit 322, a storage unit 323, a statistical processing unit 324, a setting unit 325, and a guide unit 326.

First, the input unit 321 provides a function for inputting a location, a use time, and a weather in which the user is located through the input button 274 of the platform 200.

The platform 200 is provided with at least one input button 274, in which case it is also possible to include a display panel 275 in which the information input from the input button is displayed. It is desirable to provide only the input button to prevent the cost and to reduce the case manufacturing cost.)

 One of the input buttons 274 has a function of storing a specific place according to the number of touches, such as place A (for example, home) when pressed once and place B (for example, company or school) when pressed twice. The other one of the input buttons 274 sets a time such as 9 AM when touched once and 10 AM when touched twice, and determines a start time when long presses, and then moves to the next touch count. It provides the function to set the time required from the start time, such as 1 hour, 2 hours.

In addition, another input button 274 allows the user to input the weather, for example, sunny on one touch, cloudy on two touches, rain on three touches, and storage on long presses, such as storage on long presses. Provides the ability to select

The input button 274 is for setting the test location, the test time, and the test weather to determine how much power is charged through the solar cell in the actual test, based on the conditions set by the user. Provides full functionality.

After processing the command to receive the weather information from the database, and receives the weather information through the communication unit 331) to receive the weather information of a specific date and time for a specific area automatically.

The test unit 322 provides a function of performing solar cell charging for a predetermined time by exposing the actual solar cell 220 to the outside at the time, place, and weather inputted through the input unit 321.

That is, when the test condition setting is completed through the input unit 321, the button is provided by the test unit 322 to start charging from the actual solar cell.

The test unit 322 performs a test in order to minimize the error that may occur when theoretically presenting the expected charge amount of the solar cell by running the test several times under different conditions and conditions based on a specific place. It provides a premise function that enables the user to identify the optimal amount of generated power in the environment.

The storage unit 323 stores the amount of power charged under the test conditions set by the input unit 321 through the test unit 322 and processes the actual amount of power generated in relation to the time zone, place, and weather at the input unit. To perform.

The statistical processing unit 324 serves to determine the amount of power that can be obtained under the corresponding conditions by statistically processing the actual amount of power charged according to various times / places / weather input through the input unit 321. If two tests were run under the same input conditions, the averaged power would be derived, and if the locations were the same, the amount of charging power that would change over time and weather could also be calculated.

That is, the statistical processing unit 324 compares the actual amount of power charged according to the various time / place / weather input through the input unit 321, that is, the database stored in the storage unit according to each time zone, place, and weather, and then Based on the location, it is possible to grasp the estimated charge amount which may be different from the actual charge amount according to the time zone and the weather at a certain error range level. For example, when the actual charge amount is A-6, it is 2-6 hours. In order to estimate the estimated charge amount by combining the level of reduction in A by calculating the time division equal division calculation or the change in the angle at which sunlight is irradiated.

The setting unit 325 provides a function of inputting a desired place, time, and weather through an input button like the method of the input unit in order to determine an amount of power that a user can obtain in a specific situation.

That is, the setting unit 325 is a function that can be executed after the user has tested the actual amount of power in a specific situation as described above, and if the user inputs the setting unit 325 through the storage unit If not recorded in 323, a message or a sound such as "the situation is not stored" may be displayed, or the stored data for the similar situation may be guided.

In addition, the setting unit 325 may include a communication setting unit 340.

In particular, the communication setting unit 340 is configured to automatically determine a setting value for the weather. Like the communication input unit 330, a portable electronic device having a communication function (for example, a mobile communication terminal) and a near field communication ( And a communication unit 341 capable of Bluetooth communication, etc., and communicating with the Meteorological Agency database containing the forecast weather information via the portable electronic device (or the Meteorological Office in advance through the portable electronic device). After the command processing to receive the weather information from the database, and receives the weather information through the communication unit 341) to receive the weather information of a specific date and time for a specific region, place automatically.

That is, the user can set the time and place directly in a specific situation, but because it is not easy to know the weather information for the time, provides a feature to automatically set the weather forecast according to the expected weather input information of the communication setting unit .

The guide unit 326 predicts the amount of power that can be charged through the solar cell 220 in a specific situation (that is, when a specific place has a specific time zone and a specific weather) recognized by the setting unit 325. It is a function of guiding the information, and because it is statistically processed through the values tested in the actual environment and conditions, it provides a characteristic that can guide the numerical value much more accurately than the theoretical expectation.

The guide unit 326 may provide a display function such as the display panel 275 to output guide contents through the display panel 275.

The light quantity guide module 320 is expected to be actually charged to the user in a specific situation in advance in consideration of the large amount of power charged to the battery through the solar cell 220 according to the specific time zone and weather at the place where the user is located. Power consumption is not based on theoretical estimates but based on actual test results data, allowing users to know more specifically and realistically how much power they can get in a particular situation, so they have more careful and ready battery power. Provide a role to help.
