[0002] Currently, the control systems of photovoltaic panels generally adopt a single-board independent control mode, which has the following limitations:

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] The object of the present invention is to provide a linkage type photovoltaic power station that is portable and easy to install, so as to solve the problems existing in the prior art.

[0031] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1:

[0033] This embodiment provides a linkage type photovoltaic power station that is portable and easy to install, as Figure 1 and Figure 2 shown, including:

[0034] Photovoltaic panel assemblies 1, there are multiple photovoltaic panel assemblies 1, and the multiple photovoltaic panel assemblies 1 are networked through MESH;

[0035] Energy storage assembly 2, the energy storage assembly 2 is electrically connected to the photovoltaic panel assemblies 1, and is used for storing and transporting the electric energy generated by the photovoltaic panel assemblies 1;

[0036] Detection assembly 3, the detection assembly 3 is arranged on the photovoltaic panel assemblies 1, and is used for collecting the state information of the photovoltaic panel assemblies 1, the energy efficiency information of the energy storage assembly 2 and the environmental information;

[0037] Control platform 4, the control platform 4 establishes communications with the photovoltaic panel assemblies 1, the energy storage assembly 2 and the detection assembly 3 respectively, and is used for receiving the state information of the photovoltaic panel assemblies 1, the energy efficiency information of the energy storage assembly 2 and the environmental information, generating a control scheme after analysis, and controlling the operation of the photovoltaic panel assemblies 1 and the energy storage assembly 2.

[0038] As an implementation manner, for the specific structure of the photovoltaic panel assemblies 1, please refer to Figure 3The photovoltaic panel assembly 1 includes a mounting base 11, and a protective sleeve 12 is vertically provided on the upper surface of the mounting base 11. The purpose of the protective sleeve 12 is to protect and store the wiring harness, because the photovoltaic panel assembly 1 needs to be provided with cables for transmitting electrical energy, and at the same time for control and communication. If the wiring harness is exposed to the outside, it is easy to age, and many wiring harnesses are also easy to entangle with each other. By storing the wiring harness in the protective sleeve 12, the neatness of the wiring harness can be effectively ensured; a support rod 13 is coaxially provided in the protective sleeve 12, and the bottom of the support rod 13 is transmission-connected with a rotating mechanism, and the transmission mechanism can control the rotation direction of the support rod 13. The top of the support rod 13 is connected to the photovoltaic panel 14 through an angle adjustment mechanism. The angle adjustment mechanism can control the photovoltaic panel 14 to adjust the angle, so as to adjust the direction and angle of the photovoltaic panel 14 according to the intensity of sunlight, so as to ensure that the photovoltaic panel is always at the optimal receiving surface; it also includes a photovoltaic panel control module 15, which is provided with a microprocessor, a controller, a ZigBee communication module and a 5G communication module. The controller, the ZigBee communication module and the 5G communication module all establish communication with the microprocessor. The controller is electrically connected with the rotating mechanism and the angle adjustment mechanism, and is mainly used for sending control instructions. The ZigBee communication modules of multiple photovoltaic panel components establish communication through MESH networking. Zigbee is a kind of communication technology based on IEEE 802.15.4 standard wireless communication technologies are widely used in Internet of Things (IoT) devices. The Zigbee network supports multiple topologies, and the Mesh network is a typical application. The Mesh network is a self-organizing and multi-hop network structure where devices can forward messages to each other, thus improving the network coverage and reliability. Implementing the Mesh network function in Zigbee allows devices to freely forward data packets in the network without relying on a single central node. This structure is particularly suitable for large-scale deployment scenarios such as smart homes, industrial monitoring, and large-scale agricultural applications because it improves the network flexibility and scalability. Most modern Zigbee coordinators (such as the Xbee3 series) and end devices support the Mesh network. Use a Zigbee network configuration tool (such as XCTU) to configure the coordinator and end devices. During the configuration process, it is necessary to specify whether the device is a coordinator, router, or end device. In the Mesh network of this embodiment, a ZigBee communication module is used as the coordinator, which is the central node of the network. Each ZigBee communication module can be used as the central node for data transmission. It can directly communicate with the router or indirectly communicate through multiple intermediate routers. When data needs to be sent, it first tries to directly communicate with the target device. If the direct communication fails (for example, because the target device is outside the direct communication range), the data packet can be forwarded through other routing devices (routers), thus ensuring the reliability of data transmission and achieving efficient control of multiple photovoltaic panel components in a large area, avoiding problems such as high energy consumption, delay, and poor reliability caused by single control in traditional technologies; The 5G communication module communicates wirelessly with the control platform for remote communication.

[0039] As an implementation, a counterweight groove is provided on the mounting base 11, and it can be stably installed by placing heavy objects in the counterweight groove. Of course, under conditional circumstances, it can also be installed in the mounting holes of the mounting base 11 through anchor bolts to achieve stable installation.

[0040] As an implementation, a support sliding sleeve is provided between the protective sleeve 12 and the support rod 13 to ensure the stability of the support rod 13. The friction surface of the support sliding sleeve can adopt a polytetrafluoroethylene coating, which can make the rotation smoother. It should be understood that the support sliding sleeve has through holes for the wire harness to pass through.

[0041] As an implementation manner, the rotation mechanism includes a large bevel gear 16, which is fixed to the bottom of the support rod 13. The large bevel gear 16 meshes with a small bevel gear 17, which is fixed to the power output end of a rotary motor 18. The rotary motor 18 is electrically connected to the control platform 4. By driving the small bevel gear 17 to rotate with the rotary motor 18, the large bevel gear 16 can be rotated, so as to achieve the purpose of rotating the support rod 13. In this embodiment, a low-speed motor can be used for the rotary motor 18, so that the tooth number ratio of the large bevel gear 16 to the small bevel gear 17 can be set to a reasonable value, so that a speed reducer does not need to be used for speed reduction, making the transmission more stable and the structure simpler.

[0042] As an implementation manner, the angle adjustment mechanism includes a ball seat 19, which is arranged at the central position of the back of the photovoltaic panel 14. A rotating ball 110 is rotatably arranged in the ball seat 19. The rotating ball 110 is fixed to the top of the support rod 13. An electric telescopic rod 111 is hinged between the side part of the support rod 13 and the lower part of the photovoltaic panel 14. The electric telescopic rod 111 is electrically connected to the control platform 4. The ball hinge connection structure enables the photovoltaic panel 14 to rotate freely. Of course, in order to ensure the smoothness of rotation, a polytetrafluoroethylene coating can also be arranged on the rotating surface. By stretching and contracting the electric telescopic rod 111, the angle of the photovoltaic panel 14 can be adjusted.

[0043] As an implementation manner, the energy storage component 2 includes an energy storage battery 21 and a self-use battery 22. Both the energy storage battery 21 and the self-use battery 22 are connected to the photovoltaic panel assembly 1 through a first converter 23, which is used to provide electric energy for the adjustment of the photovoltaic panel assembly 1 and transmit the electric energy generated by the photovoltaic panel 14. The self-use battery 22 is connected to the control platform 4 through a second converter 24, which is used to supply power to the control platform 4.

[0044] As an implementation manner, the detection component 3 includes a light intensity sensor 31, an electric energy monitor 32 and an attitude sensor 33. All three can adopt low-power devices and establish wireless communication with the control platform 4, so as to facilitate deployment. The light intensity sensor 31 is arranged in an array on the photovoltaic panel 14, so as to increase the comprehensiveness of the detection results.

[0045] As an implementation manner, the control platform 4 includes a central processor 41, a communication module 42 and a cloud server 43. The central processor 41 establishes communication with the communication module 42 and the cloud server 43. The communication module 42 establishes communication with the photovoltaic module 1, the detection component 2 and the energy storage component 3 for information transmission. By using the strong computing power and storage capacity of the cloud server 43, by collecting parameters such as the output power of the photovoltaic panel, the photoelectric conversion efficiency, the incident irradiance, and the angle between the sun ray and the normal line of the panel surface, the decision on the direction and angle of the photovoltaic panel is made, and the following formula is used for calculation:

[0046]

[0047] α = arcsin(sinδsinφ + cosδcosφcosω);

[0048]

[0049] Thereby, the ideal angle θ is calculated. i = 90° - α, φ i = γ; Then, the control command generated by the ideal angle is sent to the photovoltaic panel assembly 1, thereby realizing the adjustment of the direction and angle of the photovoltaic panel to achieve the best power generation efficiency.

[0050] The present invention uses specific examples to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
