The first umbrella handle 1 can be directly used for the insertion and fixing of the sun umbrella and for working support. The first reducer 4 is installed on the top of the first umbrella handle 1 by bolts, and the driving motor has a brake mechanism. The output shaft of the first reducer 4 is installed with a mounting platform by a flat key and bolts. The second reducer 5 is installed on the mounting platform by bolts. The second reducer 5 drives the motor with a brake mechanism, and its output shaft is fixedly connected to the second umbrella handle 2 by bolts. The controller 7 uses the STM32F1 series 32-bit microcontroller STM32F103C8T6 with an operating frequency of 72MHz. The chip can complete fast processing and can well complete the system's operation control, data processing, information interaction and other functions. It is installed on the mounting platform by bolts. The communicator 8 is a communication device that uses the ATK-ESP8266 serial port to WiFi module as a wireless communication method. Outdoors, it only needs to connect to the user's mobile phone hotspot WiFi to connect directly, which is convenient and fast. Compared with traditional serial port devices, it only needs simple serial port configuration to transmit data through the network, and is compatible with 3.3V and 5V single-chip computer systems, which is convenient for connecting to the system. The wireless transmission rate of this module can reach up to 54Mbps, and the frequency range is between 2.412GHz-2.484GHz. The onboard PCB antenna has a transmission power of 11-18dbm, which is fixed to the housing of the controller 7 by bolts. The locator 9 uses the NEO model series GPS positioning module, which is fixed to the housing of the communicator 8 by bolts.

The user can view the device's geographic location information through the cloud platform. If the user has an accident outdoors, the family can discover it in time and take corresponding measures. The solar tracker 10 is composed of a light-seeking tracking module. The light-seeking tracking module is mainly composed of two parts, one is a 5MM waterproof probe, and the other is a high-speed calculator. The waterproof probe is fixed to the umbrella frame 3 by bolts. The waterproof probe uses a photosensitive element. When light shines on the obstruction to form a shadow, the photosensitivity on one side forms a difference with the photosensitivity on the other side. The controller 7 controls the first reducer 4 and the second reducer 5 to move, find the photosensitivity balance point, that is, the center of the light source, so as to achieve the purpose of tracking the sun. The controller 7 will make judgments in sequence when controlling and adjusting, which is divided into three situations. First, when the photosensitivity difference at both ends of the solar tracker 10 is less than 0, the first reducer 4 and the second reducer 5 will be driven to move in the direction of smaller photosensitivity. When the two photosensitivity differences are 0, they are in the middle of the sun. Second, when the photosensitivity difference at both ends of the solar tracker 10 is equal to 0, the first reducer 4 and the second reducer 5 will not be driven to turn. At this time, the sun is in the middle. Third, when the photosensitivity difference at both ends of the solar tracker 10 is greater than 0, the first reducer 4 and the second reducer 5 will be driven to move in the direction of larger photosensitivity. When the two photosensitivity differences are 0, they are in the middle of the sun. When the two photosensitivity differences are 0, the first reducer 4 and the second reducer 5 will no longer turn, and the adjustment is completed.

[0022] Secondly, a flexible solar photovoltaic panel 6 is laid on the umbrella frame 3, and the flexible solar photovoltaic panel 6 is electrically connected to the controller 7 and fixed on the top of the umbrella frame 3. The flexible solar photovoltaic panel 6 uses a solar panel to directly convert the light energy of the sun into the electric energy required by the electrical equipment according to the principle of the photovoltaic effect, and is installed in the controller 7 in conjunction with a controller and an inverter. The controller 7 is equipped with a battery box. When working, the controller 7 can be directly powered by an external power supply or powered by a battery to ensure normal use. By setting the flexible solar photovoltaic panel 6, the battery in the battery box can be charged.

[0023] Then, the human sensor 11 is electrically connected to the controller 7 and fixed on the first umbrella handle 1. The human sensor 11 is fixed on the first umbrella handle 1 by bolts, and uses a micro-human infrared sensor to determine whether an early warning is needed. In the system, the micro-human infrared sensor is used to sense whether there is someone nearby. If there is someone nearby, a high level output is output, and the data upload mechanism is not triggered. If no one is nearby, a low level output is output. After a period of time, it is still determined that no one is nearby, and the upload mechanism is triggered. The working delay time is 2 seconds, the blocking time is 2 seconds, and it can be triggered repeatedly. Its sensing range is less than or equal to 120 degrees of cone angle, the sensing mileage is between two meters and five meters, and it works between negative 20 degrees and sixty degrees. The detection standard of the human sensor 11 is based on whether there is someone around. If there is someone nearby, a high level is sent, and if there is no one nearby, a low level is sent. The high and low levels are used as the trigger mechanism for uploading GPS positioning data of no one nearby to the cloud platform, and the trigger time is added.

[0024] Finally, the fan 12 is electrically connected to the controller 7 and fixed to the first umbrella handle 1 near the first reducer 4. The fan 12 is mounted on the first umbrella handle 1 by bolts, and a 5V DC relay is used as a rotation mechanism to control the fan 12. After the fan 12 is controlled to work, it can blow and provide a cool and comfortable environment for the user.

[0025] When the utility model is used and it is necessary to adjust the angle to achieve maximum sunshade, automatic angle adjustment can be achieved, the intensity of manual adjustment can be reduced, quick adjustment can be achieved, and it is more convenient to use. When in use, the first umbrella handle 1 is used to insert, fix and support the sun umbrella, and then the solar tracker 10 tracks the size and direction of solar energy, and then feeds the data back to the controller 7. After the controller 7 processes the data, it controls the first reducer 4 and the second reducer 5 to adjust the angle. The positioner 9 is used to collect longitude and latitude positioning data and feed it back to the controller 7. The communicator 8 is used to cooperate in communication, so as to achieve that when the angle needs to be adjusted to achieve maximum sunshade, automatic angle adjustment can be achieved, the intensity of manual adjustment can be reduced, quick adjustment can be achieved, and it is more convenient to use.
