Description

Technical Field

[0001] The utility model belongs to the field of energy technology, and specifically relates to an intelligent formulation and evaluation device and system for inspection routes of household photovoltaic power stations. Background Art

[0002] Photovoltaic power stations are developing rapidly in the energy field. However, due to their wide distribution and large number, their inspection and management has become a difficult problem that needs to be solved urgently.

[0003] There are two core problems with traditional inspection methods: first, household photovoltaic power stations are relatively scattered, and finding the specific location of each household is a tedious task; second, it is impossible to monitor and evaluate the quality of inspections in real time, which leads to many potential problems not being discovered and resolved in a timely manner.

[0004] The traditional inspection method has the following main problems that need to be solved:

[0005] The positioning of traditional inspection methods is inaccurate. Due to the lack of high-precision positioning technology, traditional methods often find it difficult to accurately find the specific location of each household when household photovoltaic power stations are widely distributed, which increases the complexity of inspection route planning.

[0006] The lack of real-time monitoring means leads to delayed problem discovery. Traditional inspection methods lack real-time monitoring means, and there is no guarantee that operation and maintenance personnel will conduct high-quality inspections on time, resulting in potential faults not being handled in a timely manner, increasing maintenance costs.

[0007] Inspection route planning is not intelligent. Traditional methods lack intelligent route planning and usually adopt fixed modes. They fail to optimize route planning, resulting in unnecessary waste of energy and time and reducing inspection efficiency.

[0008] There is a lack of real-time inspection quality assessment methods. Traditional methods cannot assess inspection quality in real time. There is a lack of means to monitor whether operation and maintenance personnel arrive at inspection points accurately, resulting in the inability to discover problems in a timely manner, affecting the overall inspection quality.

[0009] The maintenance cost is high. Due to the existence of the above problems, the traditional inspection method has great deficiencies in efficiency and accuracy, which in turn increases the maintenance and operation costs.

[0010] In view of the above factors, a household photovoltaic power station inspection route intelligent formulation and evaluation device and system are specially designed. Through high-precision positioning, real-time monitoring, low-power design and intelligent path planning, it effectively solves the problems existing in traditional inspection methods and provides a more efficient and intelligent solution for the sustainable development of household photovoltaic power stations.

[0020] The PC terminal automatically generates inspection paths for quality assessment of operation and maintenance personnel and inspection route management.

[0021] Furthermore, the PC terminal is a central system control platform, which uses an intelligent algorithm to generate an optimal inspection route based on user location information;

[0023] Furthermore, the positioning device is electrically connected to the button sensor, and the button sensor and the positioning device are installed as an integral structure, or the button sensor is installed near the user's power station.

[0024] Furthermore, the central system control platform receives the button sensor signal from the SIM800L4G module and updates the inspection status in real time according to the received button signal.
