Embodiment 1

[0028] Embodiment 1: An intelligent photovoltaic controller, including a control box 1, a power module 102 and a wireless module 103 are installed inside the control box 1, and a joint 101 is installed at one end of the control box 1, and the inner side of the joint 101 is provided with an automatic reinforcement rotating components;

[0029] Grooves are embedded on both sides of the joint 101. The control box 1 is divided into a main control box and a sub-control box. The main control + sub-control structure is used to control 3 or more motors. The main control box collects sub-control via 485 lines For voltage, current and position information, the 485 line is a 4-core line, respectively, 485A, 485B, power supply is positive, power supply is negative, and the 485 line of the sub-control box of multiple motors uses a 485 bus structure communication with one input and one output;

[0030] Among them: the reference manual attached image 3 , the main control box will collect t...

Embodiment 2

[0031] Embodiment 2: with reference to instruction manual Figure 4 , 5 and 6, it can be seen that the difference between embodiment 2 and embodiment 1 is that the rotating assembly includes a sliding frame 2, a fixed frame 201, a rotating sphere 202, a swash plate 203, a swing frame 204, a bracket 3, a rotating shaft 301, a sleeve 302 and The telescopic rod 303, the sliding frame 2 slides on both sides inside the joint 101, the fixed frame 201 is fixed on both sides inside the joint 101, the rotating sphere 202 is hinged on both sides of the sliding frame 2, and the swash plate 203 swings on one side of the rotating sphere 202. side, the swing frame 204 swings on the inner side of the swash plate 203, the bracket 3 is folded on one side of the swing frame 204, the rotating shaft 301 rotates on the inside of the bracket 3, and the sleeve 302 and the telescopic rod 303 telescopically slide on the inside of the bracket 3;

[0032] The inside of the fixed frame 201 is hollow, an...

Embodiment 3

[0039] Embodiment 3: with reference to instruction manual Figure 5 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that the side of the joint 101 close to the sliding frame 2 swings with a connecting rod 4, and the side of the connecting rod 4 rotates with a disc 401 and a snap-in disc 402. The lower end of 4 is embedded with a groove, the disk 401 and the clamping disc 402 are rotated on both sides inside the joint 101, and the clamping disc 402 is arranged in a semicircular arc shape;

[0040] Wherein: the swash plate 203 is embedded in the lower end of the connecting rod 4, and at the same time drives the connecting rod 4 to swing at an angle. When the connecting rod 4 swings, it drives the disc 401 to rotate, and the disc 401 synchronously drives the clamping disc 402 to swing, so that the clamping disc 402 can be used to The outer side of the antenna plug is limited and fixed, so that the connector 101 can automatically limit and fix th...

Abstract

The invention provides an intelligent photovoltaic controller, which comprises a control box, wherein a power supply module and a wireless module are installed in the control box, a connector is installed at one end of the control box, a rotating assembly capable of being automatically reinforced is arranged on the inner side of the connector, grooves are embedded in the two sides of the interior of the connector, the control box is divided into a main control box body and a sub control box body, a main control and sub-control structure is adopted to control three or more motors, the main control box collects sub-control voltage and current and position information through a 485 line, the 485 line is a four-core line, and wireless communication is communication between upper computers on the background of the main control box. According to the invention, due to the fact that a product is in a static state in most of time within a time period of one day, when the motor does not operate, the communication frequency can be automatically reduced, the communication frequency with the background is increased to ensure communication, so that the problem of asynchronous tracking caused by voltage imbalance is solved; and through mutual communication, a driving structure of one host and multiple extension control boxes is adopted.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to an intelligent photovoltaic controller. Background technique [0002] Photovoltaic controller is an automatic control device used in solar power generation systems to control multi-channel solar battery arrays to charge batteries and batteries to supply power to solar inverter loads; [0003] Since the photovoltaic controller needs to be connected to the antenna through the interface, and the antenna plug is easy to fall off after the photovoltaic controller is used for a long time, the existing photovoltaic controller cannot be embedded in the antenna plug for automatic reinforcement; [0004] Aiming at the technical problems of the photovoltaic controller mentioned above, after searching, it is found that there is a patent No. CN201611141321.9, a portable MPPT photovoltaic controller, which has good waterproof and dustproof effect , improve the service life of t...
