Solar combiner box data acquiring and processing module supportive to multiple communication formats

Abstract

The invention provides a solar combiner box data acquiring and processing module supportive to multiple communication formats. The solar combiner box data acquiring and processing module supportive to the multiple communication formats is capable of acquiring and processing various operating data and related environmental parameters of devices in a solar combiner box, and converting the data into various communication protocol formats according to operating needs, so that needs of various control systems can be met. Therefore, data acquiring and processing efficiency is improved, setting and operation of the systems are more simplified, and the solar combiner box data acquiring and processing module supportive to the multiple communication formats enables the combiner box to be suitable for wider application conditions.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar combiner box data acquisition and processing module supporting multiple communication formats. Background technique [0002] More and more attention has been paid to the solar power generation industry, and it has also been widely used in the world. The traditional solar combiner box does not have a monitoring function, or only processes the monitoring data inside the combiner box, and then transmits it to the next-level control unit through 485 or other field buses. [0003] However, as solar photovoltaic power plants are getting more and more attention, the scale of solar photovoltaic power plants is also increasing, and the scope of construction around the world is becoming wider and wider. The traditional monitoring and control communication methods of solar combiner boxes have begun to appear. The following problem arises: refer to figure 1 , between...

Problems solved by technology

[0003] However, as solar photovoltaic power plants are getting more and more attention, the scale of solar photovoltaic power plants is also increasing, and the scope of construction around the world is becoming wider and wider. The traditional monitoring and control communication methods of solar combiner boxes have begun to appear. The following problem arises: refer to figure 1 , between each combiner box and inside the combiner box, only a single communication format is used for data transmission. In this way, data transmission mismatches often occur due to different communication protocols in the process of sending and receiving.

In addition, most solar power plants are located in the wild, in the desert, and need to be unattended. Therefore, it is necessary to carry out fully automatic 24-hour monitoring of the power plant. In the monitoring system of the entire power plant, there are various communication protocols that are incompatible with each other. Communication is the biggest problem in networking

[0004] In summary, when applied to large-scale solar power plants, the solar combiner box data acquisition and processing module that only supports a single communication format has gradually failed to meet the needs of use
