Embodiment 1

[0069] see figure 1 , the embodiment of the present invention provides a kind of solar system, and this solar system comprises several solar components 10, at least one junction box 13 and central controller 11; Each junction box 13 is connected with at least one solar module 10; Central controller 11 and Each junction box 13 is connected; the central controller 11 is communicatively connected with the external control system.

[0070] Compared with the application scenarios with a large number of solar modules, figure 1 The solar system shown is more suitable for application scenarios where the scale of solar modules is relatively small, such as a scenario where the number of junction boxes 13 in the solar system is less than 100. In a scene with a large number of solar modules, the number of junction boxes 13 is correspondingly large. If all junction boxes 13 are directly connected through the central controller 11, the amount of data that the central controller 11 needs to...

Embodiment 2

[0129] An embodiment of the present invention provides a solar energy system control method. The control method is based on solar energy systems such as figure 1 As shown in or 2, the subject of execution of this method is the central controller 11 included in the solar energy system provided in the above-mentioned embodiment 1. Such as Figure 4 As shown, the method specifically includes the following steps:

[0130] Step 101: The central controller 11 receives the component control information sent by the external control system.

[0131] The above-mentioned external control system includes a remote control system and a local control system. Wherein, the remote control system is a system that needs to be connected through the Internet, such as the server cluster 30, the user terminal 40, and the like. The local control system is a self-contained system in the place where the solar energy system is installed, such as a fire protection system 20, a monitoring system, and t...

Embodiment 3

[0152] Such as Figure 6 As shown, the embodiment of the present invention provides a solar energy system control device, which is used to implement the control method provided in the above-mentioned embodiment 2. Specifically, the device includes:

[0153] A receiving module 30, configured to receive component control information sent by an external control system;

[0154] The execution control module 31 is configured to execute control operations corresponding to the component control information on the solar components 10 connected to the junction box 13 according to the component control information.

[0155] The execution control module 31 is used to analyze the component control information, determine the component to be controlled corresponding to the component control information; execute the control operation corresponding to the component control information through the junction box 13 associated with the component to be controlled.

[0156] In the embodiment of t...

Abstract

The invention provides a solar energy system control method and device, a central control unit and a solar energy system, and belongs to the field of solar energy. The method comprises the steps thatthe central control unit receives module control information sent by an external control system; according to the module control information, control operation corresponding to the module control information is executed on a solar energy module connected with a junction box. Accordingly, by connecting the central control unit with the external control system, and conducting remote configuring, controlling, maintenance monitoring and the like on the solar energy system through the external control system, the system safety, stability and reliability are enhanced. Automatic module state data obtaining and remote anomaly detection are achieved, people for on-site maintenance are reduced, and the personal safety problems such as climbing and falling or electric shock are avoided. The central control unit can communicate with a fire extinguishing system, the solar energy module can be turned off through control of the fire extinguishing system under the conditions such as fires or earthquakes, the phenomenon that high voltage of the solar energy system causes electric shock injury to personnel is avoided, and the safety performance of the solar energy system is improved.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar energy system control method and device, a central controller, and a solar energy system. Background technique [0002] BIPV (Building Integrated Photovoltaic, Building Integrated Photovoltaic) is a technology that integrates solar power generation products into buildings, using solar modules to integrate solar curtain walls, daylighting roofs, etc. on buildings. [0003] At present, BIPV technology usually installs a solar power generation system on the outer surface of the building envelope, and converts solar energy through the solar power generation system to provide electricity. Among them, the solar power generation system includes solar modules and junction boxes. Several solar modules are connected in series and parallel, and finally converged through the junction box to form a solar power generation system. [0004] However, the above-mentioned solar power ...
