Solar photovoltaic module array data collection device and data processing method thereof

Abstract

The invention relates to the technical field of solar energy, and especially relates to a solar photovoltaic module array data collection device and a data processing method thereof. The data collection device is internally provided with a data collection processing chip, a communication assembly connected with the data collection processing chip, a standard internet access and / or a USB interface connected with the data collection processing chip, a wired internet of things interface connected with the data collection processing chip, a current sensor connected with the data collection processing chip, and a power supply system connected with the data collection processing chip. The device has wired and wireless internet of things networking functions, and engineering application is wide. A 433 wireless communication module is used to acquire operating data of a solar photovoltaic module, a relay is not needed, and network structure is simplified into a two-layer structure, so complexity is low and networking is easy. The device is fast in data acquisition speed and good in real-time property. The device is excellent in wireless network performance, wide in coverage, and holds more number of inferior nodes.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar photovoltaic module array data collection device and a data processing method thereof. Background technique [0002] At present, the working data of the solar photovoltaic power generation system (including the working data of the battery panel, the working data of the inverter, and the working data of the power transmission and transformation equipment) are generated by each discrete device and submitted to the upper computer system. Different types of equipment and different manufacturers have different data specifications and physical interfaces, resulting in inconsistent software and hardware interfaces of the upper computer system, and heavy workloads for software development and maintenance. When replacing and upgrading existing equipment, it is necessary to modify the upper-level application software, which has a large economic cost and has a high security ris...

Different types of equipment and different manufacturers have different data specifications and physical interfaces, resulting in inconsistent software and hardware interfaces of the upper computer system, and a large workload for software development and maintenance

When replacing and upgrading the existing equipment, it is necessary to modify the upper application software, which has a large economic cost and has a high security risk and is not feasible for the operating power station system.

At the same time, ZigBee wireless network is generally used when collecting the working data of each node of the solar photovoltaic panel array. The disadvantages of ZigBee wireless network are slow speed and low real-time performance. The number of node access of the converging device is limited
