However, it should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention.

Further, the four-quadrant optical tracker 7 is a cylinder, and several photoelectric sensors are installed on the bottom of the cylinder, and several photoelectric sensors form a photosensitive plane, and the diagonal lines of the photosensitive plane divide it into four photosensitive quadrants area.

Further, the control mechanism 9 includes a photovoltaic charging control module, a power module, and an MCU controller; the photovoltaic charging control module is connected to the power module, the power module is connected to the power terminal of the MCU controller, and the MCU controller is respectively connected to the photoelectric sensor, DC geared motor, DC push rod motor connection.

The working principle of this specific embodiment is: the STM32 series single-chip microcomputer is adopted as the microcontroller, which is based on the ARM Cortex-M3 core controller designed for applications requiring high performance, low cost, and low power consumption. Its core chip volume Small and powerful, it can meet the requirements of the system for the controller. A lot of functional modules are integrated inside, and users can call them at will according to their needs, and there is no need to design additional peripheral additional circuits. Moreover, the control precision is high and the operation speed is fast. The internally integrated RTC clock module and the internally generated PWM signal are used. The mechanical structure is controlled by two parts of the sun azimuth and elevation. The azimuth angle is controlled by DC deceleration motor gear transmission, and the elevation angle is controlled by the withdrawal and contraction of DC push rod motor. The whole design is divided into two parts, namely the sun tracking control part and the photovoltaic power generation part.

The solar cooker uses photoelectric tracking to track the light. It uses photoelectric sensors to detect the altitude and azimuth of the sun. Under the condition that the sun is vertically irradiated, for the solar cooker, if the light intensity in all directions is the same, the output signal of the photoelectric sensor is 1; When the light is strong, the azimuth motor is controlled to rotate to make the solar cooker rotate to the left. During the light tracking process, the azimuth angle is adjusted first, and then the elevation angle is adjusted to achieve two-axis precise tracking of the sun. This tracking mode has the characteristics of high precision and fast speed, but it has a high response to the sensitivity of the photoelectric sensor and the control circuit.

In the sensor selection, a photosensitive plane is made with a photodiode array to detect the position of the sun. As shown in Figures 4 and 5, the bottom of the cylinder represents a photosensitive plane, and the four areas divided by diagonal lines represent four photosensitive quadrants. Figure 4 shows direct sunlight, and the light irradiates the bottom surface to form a circular spot, indicating that the light is perpendicular to the photosensitive plane below. Figure 5 shows that the sunlight is obliquely irradiated to the left area outside the circular spot, indicating that the sunlight is not perpendicular to the photosensitive plane, and its azimuth and elevation angles need to be adjusted so that the light is perpendicular to the photosensitive plane. After experiments, when the sun's rays shine on the left and right of the circular area, adjust the azimuth angle, and adjust the elevation angle when the sun's rays shine on the left and right sides of the circular area, so that the photosensitive plane is perpendicular to the sunlight. Install the photoelectric sensor on the solar cooker, adjust the angle through the control system, make the largest circular plane of the solar cooker parallel to the photosensitive plane, and make the photosensitive plane perpendicular to the sunlight. Chasing light effect.

It adopts STM32 series single-chip microcomputer, which has ARM Cortex-M3 core designed for embedded applications requiring high performance, low cost and low power consumption. It is small in size and powerful in function, which can meet the system's requirements for light tracking control.

The azimuth rotation uses a miniature DC motor with worm gear reduction, which has two characteristics: (1) The worm gear reduction motor is self-locking, that is, the output shaft cannot rotate when the motor is without power, that is, Self-locking, the self-locking force is 1.2 times the rated torque. (2) The direction of the output shaft of the reduction box is perpendicular to the motor shaft, and the output shaft of the entire motor body is shorter than that of the ordinary geared motor, which is suitable for some occasions that require this aspect of the installation size.

The elevation angle actuator uses a push rod motor, which is a motor that is decelerated by a worm gear, and cooperates with a screw nut to convert the rotational motion of the motor into a linear motion, and uses the forward and reverse rotation of the motor to control the expansion and contraction of the electric push rod, so as to achieve the regulation of the solar cooker elevation angle.

The motor drive adopts the MC33886 module with high current and low impedance. The working voltage is 5-12V, and the maximum driving current is up to 5A. , Easy to install features.
