Problems solved by technology
However, due to the large number of photovoltaic cell module arrays, the layout area is large, manual or wired monitoring is inefficient, and the cost is high
Although the patent number 201520395866.7 adopts the wireless data transmission method, the monitoring data of the photovoltaic battery module is not stored in the database of the upper computer management system, and the current working status of the battery module can only be judged according to the currently received data
This is not conducive to summarizing the historical working status of battery components, nor is it conducive to making a correct assessment and prediction of the future working status of battery components

The invention discloses a wireless monitoring system of an intelligent photovoltaic array. The wireless monitoring system comprises intelligent junction boxes, a base station and a monitoring upper computer. With the adoption of the intelligent junction boxes, fusion and wireless transmission of acquisition data are achieved by a uniform clustering ad-hoc network routing algorithm of a wireless sensing network; and the monitoring upper computer end is combined with a network database and an intelligent alarm system to store and analyze a working parameter of a battery module and estimate the working state. With the adoption of a wireless ad-hoc network transmission technology, and the wireless monitoring system has the advantages of low cost, high efficiency, expandability and the like, and can be applied to the field of power generation monitoring of a large-sized photovoltaic array.
Description
technical field [0001] The invention relates to an intelligent junction box and a photovoltaic array wireless monitoring system based on the intelligent junction box, belonging to the field of photovoltaic power generation. Specifically, it is a wireless sensor network monitoring system based on a uniform clustering ad hoc network routing protocol. Background technique [0002] As a renewable and non-polluting energy source, solar energy has been valued in the energy field for its abundant resources and easy access. As the main form of utilizing solar energy, photovoltaic power generation has significant energy, environmental protection and economic benefits, and has been widely used. [0003] Since the photovoltaic cell modules are connected in series, the maximum current flowing in the string depends on the photovoltaic cell module with the worst performance, that is, a damaged photovoltaic cell module can make the performance of the entire string deteriorate. Therefore,...
