Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a photovoltaic equipment management and positioning system and method based on RFID. Background Art

[0002] Energy is related to the long-term development of mankind. Photovoltaic power generation is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. On the one hand, the photovoltaic industry can greatly alleviate the current shortage of non-renewable energy and further ensure the security of China's energy supply.

[0003] The power industry requires high continuity of safe production. When photovoltaic power generation operations cannot proceed normally, it will greatly affect the production of enterprises. Power plants need to quickly troubleshoot and locate the fault point for maintenance and restore power supply. With the rise of the concepts of smart power plants and digital power plants, the importance of power plant inspection methods in modern power plant management is becoming increasingly significant. When photovoltaic panels cannot generate electricity for transmission normally, maintenance personnel need to navigate to the photovoltaic panel control area as soon as possible and accurately find the corresponding photovoltaic controller of the faulty photovoltaic panel for subsequent maintenance work.

[0004] The photovoltaic power generation system mainly consists of solar panels, inverters, photovoltaic controllers, batteries, power distribution systems, lightning protection and grounding systems, etc. Among them, energy storage equipment and photovoltaic controllers are key factors affecting system cost and life. In actual applications, each photovoltaic panel corresponds to a photovoltaic controller. When deployed in large quantities, all photovoltaic controllers may be placed in different places. When maintenance personnel need to perform maintenance, it is difficult to quickly find the photovoltaic controller corresponding to a photovoltaic panel, which poses a great challenge to subsequent system management and maintenance. At present, the common method is to paste QR code information on each photovoltaic controller to identify the corresponding photovoltaic panel information. However, in outdoor environments, QR codes are easily contaminated and cannot be identified, and are also easily blocked. In addition, this method will consume a lot of manpower costs and time in actual applications by simply searching with the naked eye. Summary of the invention

[0028] S1 deploys photovoltaic equipment tags to multiple photovoltaic equipment and transmits the collected data to server 1 in real time;

[0029] S11 first installs the photovoltaic equipment tag, satellite positioning and communication unit 22 on the photovoltaic controller 2;

[0030] Specifically, based on commercial high-sensitivity tag chips, through proprietary designs of antennas, materials and appearance, special RFID tags are realized according to the photovoltaic controller 2 with different characteristics; if placed inside the device, it can also be an ordinary paper label, which will be collectively referred to as photovoltaic equipment tags later. The RFID photovoltaic equipment tag is bound to the photovoltaic controller 2, and the photovoltaic controller 2 is equipped with a satellite positioning and communication unit.

[0031] S12 writes the system identification information assigned by the photovoltaic controller 2 into the photovoltaic device tag;

[0042] Specifically, during routine inspections, maintenance personnel can use the handheld device 3 to query the approximate location of the photovoltaic controller 2. When near the photovoltaic controller 2, maintenance personnel can use the handheld device 3 to query the operating status of nearby photovoltaic panels, such as the charged voltage of the battery, the temperature and humidity values ​​of the photovoltaic panel collecting solar energy environment, etc.; when there are no abnormalities, the time, number, status, etc. of this inspection are recorded; according to the seasonal characteristics of photovoltaic power generation, the photovoltaic controller 2 can set the undervoltage protection value of the battery to better smooth the peak of the power grid and improve the economic benefits of the power grid operation.
