Cell slice tracking information generating method and system, and tracking method and system

Abstract

The invention relates to a cell slice tracking information generating method and system, and a tracking method and system. The generation method comprises: obtaining a corresponding case number according to a cell slice case; establishing corresponding box numbers for the cell slice boxes in the cell slice case according to the case number; establishing corresponding cell slice numbers for the cell slices in the cell slice boxes according to the box numbers; series welding the cell slices according to the case number, boxes numbers and cell slice numbers, and establishing corresponding serial numbers for the cell slices after series welding; and arranging cell slice strings according to position information, and establishing module numbers for the cell slice modules after string arrangement. The tracking method can track cell slices according to the generation method, track cell slice production line, production processes, production time, etc., and effectively avoid photovoltaic module faults.

Description

technical field [0001] The invention relates to the field of photovoltaic module production, in particular to a method and system for generating cell tracking information, and a tracking method and system. Background technique [0002] Photovoltaic modules are the core part of the solar power generation system, and also the most important part of the solar power generation system. Photovoltaic modules are usually composed of solar cells combined. The current and voltage of a single solar cell are very small. After connecting multiple cells in series, a high voltage can be obtained, and a high current can be obtained after parallel connection, and then passed through a diode (to prevent Current input) can output the current, so as to enter the practical field. [0003] In addition to the shape and size, single-poly crystal type, power level, current level, etc., the information of the battery sheet also includes information such as its process, production line type, and prod...

Problems solved by technology

[0004] When there is an abnormality in the photovoltaic module, for the abnormal cell, through the MES system, only the supplier of the cell, the type of the cell, and the electrical performance can be found out, but the production type, production process, and production time cannot be tracked As a result, it is impossible to conduct a comprehensive investigation on cells of the same production line, production process, and production time, and subsequent photovoltaic modules may have the same problem
