[0072] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0073] It is understandable that distributed photovoltaic power generation has been rapidly developed and promoted. The use of distributed photovoltaic power generation can be used to sell electricity in addition to household electricity consumption, thereby increasing the income of photovoltaic households. In this process, the information transmission of photovoltaic equipment plays a particularly important role. However, in the existing technology, the way of photovoltaic equipment information transmission is relatively simple and fixed, and it is impossible to expand the scope of electricity sales through blockchain technology, resulting in the inability to maximize the consumption and income of photovoltaic power generation.

[0074] To solve the above problems, an embodiment of the present invention discloses a photovoltaic equipment information transmission method and system based on blockchain, which determines the target photovoltaic family and the target photovoltaic equipment, monitors the electricity consumption and power generation in the period, obtains the target monitoring data, calculates the family benefit ratio and the remaining power in the period; compares the family benefit ratio with the preset standard benefit ratio, and compares the remaining power in the period with the preset standard remaining power; when the family benefit ratio is greater than the standard benefit ratio, generates targeted sales information, selects auxiliary photovoltaic equipment, builds an auxiliary communication channel with the target photovoltaic equipment, and transmits the targeted sales information based on blockchain technology; when the family benefit ratio is not greater than the standard benefit ratio, and the remaining power in the period is greater than the standard remaining power, generates regional coordination information, and broadcasts the regional coordination information internally; when the family benefit ratio is not greater than the standard benefit ratio, and the remaining power in the period is not greater than the standard remaining power, performs photovoltaic power generation storage, or generates and publishes request coordination information. It can calculate the household benefit ratio and the remaining electricity in each period, conduct comparative analysis, and in different situations, based on blockchain technology, transmit targeted sales information, or broadcast regional coordination information internally, or issue request coordination information, thereby effectively expanding the scope of electricity sales and maximizing the consumption and benefits of photovoltaic power generation.

[0075] Specifically, Figure 1 A flowchart of a photovoltaic device information transmission method based on blockchain provided in an embodiment of the present invention is shown.

[0076] In a preferred embodiment of the present invention, a photovoltaic device information transmission method based on blockchain comprises the following steps:

[0077] Step S101, determine the target photovoltaic households and target photovoltaic equipment, monitor the power consumption and power generation in the periodic period, obtain the target monitoring data, and calculate the household benefit ratio and the remaining power in the period.

[0078] In the embodiment of the present invention, by determining the target photovoltaic family and the target photovoltaic equipment, the power, voltage, current, ambient temperature, solar radiation intensity, power generation, power consumption and other parameters of the target photovoltaic family are monitored in the period according to the preset monitoring period, the target monitoring data is obtained, and the unit price of photovoltaic targeted sales is obtained in real time. and Calculate the household benefit ratio according to Calculate the remaining power during the period, where: is the family benefit ratio, is the preset electricity efficiency coefficient, is the preset electricity sales benefit coefficient, is the unit price of electricity sold, is the power generation, For electricity consumption; The remaining power for the time period.

[0079] Understandably, It can represent the electricity sales benefit of the target photovoltaic household. Specifically, the higher the electricity sales price and the greater the remaining electricity in the period, the higher the electricity sales benefit. It can represent the electricity efficiency of the target photovoltaic household. Specifically, the greater the electricity consumption, the higher the electricity efficiency.

[0080] Specifically, Figure 2 A flow chart of monitoring and analyzing electricity consumption and power generation in the method provided by an embodiment of the present invention is shown.

[0081] Among them, in the preferred embodiment provided by the present invention, the determination of the target photovoltaic households and target photovoltaic equipment, monitoring of electricity consumption and power generation in the periodic period, obtaining the target monitoring data, and calculating the household benefit ratio and the remaining power in the period specifically include the following steps:

[0082] Step S1011: Determine target photovoltaic households and target photovoltaic equipment.

[0083] Step S1012: monitoring the electricity consumption and power generation of the target photovoltaic household during a period according to a preset monitoring period cycle to obtain target monitoring data.

[0084] Step S1013: Calculate the household benefit ratio according to the target monitoring data.

[0087] Step S102: compare the household benefit ratio with a preset standard benefit ratio, and compare the remaining power in the time period with a preset standard remaining power.

[0088] Step S103: When the household benefit ratio is greater than the standard benefit ratio, generate targeted sales information, select auxiliary photovoltaic equipment, build an auxiliary communication channel with the target photovoltaic equipment, and transmit the targeted sales information based on blockchain technology.

[0089] In an embodiment of the present invention, when the household benefit ratio is greater than the standard benefit ratio, it indicates that the electricity sales benefit is much greater than the electricity consumption benefit. At this time, targeted sales information is generated, and by performing linkage monitoring on photovoltaic devices in a preset internal linkage area, multiple online photovoltaic devices that can be connected to the blockchain are determined, and then the processor performance parameters, memory performance parameters, network parameters, interface protocols, firewalls, data encryption functions and other performance security data of multiple online photovoltaic devices are obtained. By comparing and analyzing the performance security data of multiple online photovoltaic devices, the online photovoltaic device with the best comprehensive performance and security is selected from the multiple online photovoltaic devices, and it is marked as an auxiliary photovoltaic device. Then, an auxiliary communication channel is constructed between the target photovoltaic device and the auxiliary photovoltaic device. Through the auxiliary communication channel, the targeted sales information is forwarded to the auxiliary photovoltaic device, and then through the auxiliary photovoltaic device, the targeted sales information is transmitted to the blockchain, so that based on the blockchain, the information integrity, non-tamperability, decentralization and automated contracts can be ensured, and the targeted sale of photovoltaic power to the target photovoltaic household can be achieved, effectively expanding the scope of electricity sales.

[0090] It is understandable that for the targeted sale of photovoltaic power, the unit price of targeted electricity sales based on blockchain is not lower than the unit price of electricity sales directly to the power grid.

[0091] Specifically, Figure 3 A flow chart of transmitting targeted selling information in the method provided by an embodiment of the present invention is shown.

[0104] Furthermore, the photovoltaic equipment information transmission method based on blockchain also includes the following steps:

[0105] Step S104: when the household benefit ratio is not greater than the standard benefit ratio and the remaining power in the time period is greater than the standard remaining power, generate regional coordination information and perform internal broadcast transmission of the regional coordination information.

[0106] In an embodiment of the present invention, when the household benefit ratio is not greater than the standard benefit ratio and the remaining electricity in the time period is greater than the standard remaining electricity, it indicates that the electricity sales efficiency is not high and the remaining electricity in the time period is large. At this time, regional coordination information is generated, and the internal broadcast addresses of multiple electricity-consuming households in the internal linkage area are obtained. Then, according to the multiple internal broadcast addresses, the regional coordination information is internally broadcast and transmitted, so that electricity-consuming households with electricity coordination needs can coordinate the use of the remaining photovoltaic electricity in the target photovoltaic households without conducting targeted sales of photovoltaic electricity.

[0107] Specifically, Figure 5 A flow chart of internal broadcast transmission of information in the method provided by an embodiment of the present invention is shown.

[0111] Step S1043: internally broadcast and transmit the regional coordination information according to the multiple internal broadcast addresses.

[0112] Furthermore, the photovoltaic equipment information transmission method based on blockchain also includes the following steps:

[0113] Step S105: When the household benefit ratio is not greater than the standard benefit ratio and the remaining power in the time period is not greater than the standard remaining power, photovoltaic power generation storage is performed, or request coordination information is generated and issued.

[0114] In an embodiment of the present invention, when the household benefit ratio is not greater than the standard benefit ratio and the remaining power in the time period is not greater than the standard remaining power, it is determined whether the remaining power in the time period is a negative value. Specifically: when the remaining power in the time period is not a negative value, it indicates that the power sales benefit is not high and there is still remaining photovoltaic power. At this time, the remaining photovoltaic power is stored for photovoltaic power generation; when the remaining power in the time period is a negative value, it indicates that the power sales benefit is not high and cannot meet the electricity demand of the target photovoltaic household. At this time, a request for coordination information is generated, and the request for coordination information is internally published and transmitted according to multiple internal broadcast addresses, and then when the electricity-consuming household that can coordinate electricity responds, the internal electricity is coordinated and used.

[0115] Specifically, Figure 6 A flow chart of publishing request coordination information in the method provided by an embodiment of the present invention is shown.

[0116] Among them, in the preferred implementation mode provided by the present invention, when the household benefit ratio is not greater than the standard benefit ratio and the remaining power in the time period is not greater than the standard remaining power, performing photovoltaic power generation storage, or generating and publishing request coordination information specifically includes the following steps:
