In addition, the main body parts 100 and 100a have the advantage that the pivoting part and the tilting part are constructed in one module frame type, so that no rework of the module frame is required during the installation process.

In addition, the main body parts 100 and 100a of the solar tracking device are equipped with heaters in the tilt part and the rotating part, respectively, to perform a winter freeze protection function.

The tilt part and the rotating part are further provided with an angle sensor connected to the local control unit 102.

The tilt part plays a role of tilting the panel 101 in a tilt angle range of 15 to 70 degrees in the north and south directions.

The rotating part is responsible for rotating the panel 101 within the rotation angle range of 270 degrees from the rotation angle reference point in the east and west directions.

The tilting and rotating parts are operated simultaneously according to the direction of sunlight to track sunlight.

In addition, the main body parts 100 and 100a are each provided with a local control unit 102 which is its own controller.

Each local control unit 102 is coupled with the central control unit 200 to be able to communicate with each other via a conventional wired communication network.

In addition, the local control unit 102 is coupled to deliver the generated power generated from the panel 101 to the power transmission facility via the central control unit 200 through the power supply network installed in parallel with the wired communication network.

The central control unit 200 performs the collection management of the generated electric power of the plurality of local control unit 102.

The power tower 400 is connected to the central control unit 200. The power tower 400 receives the generated power collected in the central control unit 200 and serves to supply the external power generation system.

The central control unit 200 is connected to a solar system 501, such as an all-weather solar system, an anemometer 502, a wind vane 503, and a measurement unit 500 provided with a communication module 504 on an upper shore. The communication module 504 communicates with the central control unit 200 to transmit the measured values measured by the solar system 501, the anemometer 502, and the wind vane 503 to the central control unit 200.

The central control unit 200 calculates a command value for following the operation path for each of the main body parts 100 and 100a based on the received measured value, and transmits each command value to the corresponding local control unit 102 for control. To perform.

The central control unit 200 predicts the tracking movement based on the astronomical data necessary for the individual tracking with local consideration, and realizes more precise solar tracking by using the measured value as a correction value of the tracking movement prediction. Together, they implement operational control to respond to changes in daily solar radiation, wind direction, and wind speed.

For example, the central control unit 200 maintains the panel 101 at an angle of 5 degrees during dark clouds to track a small amount of light, thereby maximizing power generation efficiency.

Each local control unit 102 has an individual identification code or address for distinct communication with the central control unit 200, and can be distinguished using this.
