[0012] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 , Figure 2 and Figure 3 A distributed energy system for construction shown in the figure includes an electrically connected energy supply module 1, an energy distribution module 2, an energy storage module 3 and an energy monitoring module 4. The energy distribution module 2 can distribute the electric energy generated by the energy supply module 1 to electrical appliances or store it in the energy storage module 3, and use the energy monitoring module 4 to monitor the power consumption of electrical appliances in real time. The energy storage module 3 is a battery or a lithium battery. The energy supply module 1 outputs the generated electric energy to the electrical appliances through an AC / DC converter or stores it in the energy storage module 3.

[0013] The energy supply module 1 is used to generate electric energy. The energy supply module 1 includes a solar power generation component 10, a wind power generation component 11 and an auxiliary power generation component 12. The solar power generation component 10 is arranged on the peripheral infrastructure 5 and the peripheral buildings; the wind power generation component 11 is arranged on the peripheral infrastructure 5, and the auxiliary power generation component 12 is arranged in the building area; the solar power generation component 10, the wind power generation component 11 and the auxiliary power generation component 12 provide stable power supply to the system within a preset time. The solar power generation component 10 is a solar panel, the wind power generation component 11 is a small wind turbine generator, and the auxiliary power generation component 12 is an internal combustion generator.

[0014] The peripheral infrastructure 5 includes a plurality of support columns 50 arranged along the circumference of the area to be constructed and a protective fence 51 sequentially connecting the plurality of support columns 50. The wind power generation assembly 11 is arranged on the top of the support column 50, and the solar power generation assembly 10 is arranged on the outside of the protective fence 51. The solar power generation assembly 10 is also arranged on the top of the staff dormitory and material warehouse set up in the construction area and the non-construction operation area, so as to avoid the solar power generation assembly 10 occupying the construction area. In the specific implementation, a galvanized iron plate can also be fixedly installed on the protective fence 51 to shield the area that the solar power generation assembly 10 does not cover.

[0015] The supporting column 50 includes a supporting base 500 fixed to the ground by anchor bolts, a column 501 detachably mounted on the top of the supporting base 500 by bolts, and a plurality of connecting members 502 fixed on the side walls of the column 501 by bolts. The protective fence 51 is mounted on the connecting member 502. Specifically, a snap-in groove is provided on the connecting member 502, and an inverted L-shaped snap-in protrusion is provided on one side of the protective fence 51. The inverted L-shaped snap-in protrusion is detachably mounted in the snap-in groove for easy installation and disassembly. In order to further improve the reliability of the connection, bolts can also be used to reinforce the connection between the protective fence 51 and the connecting member 502.

[0016] The lighting and warning module 7 can be removably installed on the support column 50 through fasteners. The lighting and warning module 7 includes a searchlight and a voice alarm. The searchlight can provide light for night operations or patrol operations in the work area, and can also warn non-operating personnel near the work area through the voice alarm, which has a good warning effect. The support column 50, the protective fence 51 and the lighting and warning module 7 form a modular installation, which can be recycled in different construction sites. Of course, a monitoring system can also be installed on the support column 50 to improve the function of the module. The peripheral infrastructure 5 can maintain the construction area and has good protection capabilities. The solar power generation component 10 and the wind power generation component 11 can also be installed on it, which can be used for multiple purposes and reduce construction costs.

[0017] The energy distribution module 2 is used to distribute the electric energy generated by the energy supply module 1 according to a preset method. The energy distribution module 2 is a microgrid controller. The microgrid controller can preferentially supply the electric energy generated by the energy supply module 1 to nearby electrical appliances or store it in the energy storage module 3. In this embodiment, the energy distribution module 2 can adopt the S077 power distribution module produced by Suzhou Shimaide Electric Co., Ltd., and of course other power modules can also be used. The energy monitoring module 4 is used to monitor the power consumption of electrical appliances and the storage power of the energy storage module 3. Specifically, the energy monitoring module 4 can adopt the energy consumption monitoring terminal equipment purchased on the market, or it can use the existing technology to manufacture a matching monitoring module according to the structural system of this system.

[0018] like Figure 1 , Figure 2 and Figure 3 A control method for a distributed energy system for building construction is shown, the control method comprising the following steps: Step 1: Before the construction, a peripheral infrastructure 5 is set up outside the building area to be constructed, and temporary shed structures such as dormitories and material warehouses required for construction are set up in the area enclosed by the peripheral infrastructure 5 and outside the area to be constructed. Then the energy supply module 1 and the energy storage module 3 are installed according to the designed position. Specifically, the solar power generation component 10 is installed on the temporary shed structures required for construction such as the protective fence 51, dormitories, and material warehouses. When installing the solar power generation component 10, a fixed bracket can be selected for installation, or a rotating bracket with an adjustable angle can be selected to improve the power generation efficiency of the solar power generation component 10. The wind power generation component 11 is installed on the top of the supporting column, and the installation has a certain height to avoid harm to personnel when the fan blades rotate. Due to the high installation height, the ventilation is better and the power generation capacity is stronger. The energy storage module 3 is set in a safe area with a distance of not less than 5m from the construction area, and a protective structure is built to ensure the safety performance of the installation and use of the energy storage module 3. Then the energy distribution module 2 and the energy monitoring module 4 are installed to form a distributed energy system.

[0019] Step 2: Use the solar power generation components 10 and the wind power generation components 11 to generate electricity from light energy and wind energy in real time. The energy distribution module 2 supplies the electrical appliances near each power generation component according to the principle of priority proximity, and stores the remaining electrical energy in the energy storage module 3. The method of supplying power according to the principle of priority proximity can reduce the length and complexity of cable layout, and is also convenient for modular design with a high degree of integration.

[0020] Step three, use the energy monitoring module 4 to monitor the power consumption of electrical appliances in the system in real time. When the detected power generation is less than the power consumption, the energy storage module 3 releases electric energy to power the system; when the amount of electricity stored in the energy storage module 3 reaches the lower limit of the preset value and the power generation is less than the power consumption, the auxiliary power generation component 12 is started to supplement the system with electric energy, so as to ensure the stability of electric energy provided and the efficiency of clean energy utilization, and minimize carbon emissions.

[0021] The above embodiments are only some illustrations of the concept and implementation of the present invention, and are not intended to limit the same. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
