Photovoltaic module flexible manufacturing control system based on field bus

Abstract

The invention provides a photovoltaic module flexible manufacturing control system based on a field bus. The control system comprises an upper computer subsystem, a primary field station, a line control subsystem and a special equipment subsystem. The systems are connected through the Ethernet, Profibus and ASI (actuator-sensor-interface). The system is capable of monitoring production process information of photovoltaic modules in real time, and realizes functions of rhythm adjusting, quality tracing, automatic fault alarming and the like of production lines.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic modules, in particular to a fieldbus-based flexible manufacturing control system for photovoltaic modules. Background technique [0002] Current flexible systems for PV module manufacturing have the following disadvantages: [0003] 1. Decentralized control is adopted, each manufacturer has its own control, there is no unified standard, data collection is inconvenient, and it is difficult to realize centralized control of the entire production line; every time the specification is changed, each special machine must be adjusted one by one, which delays time , affecting production efficiency. [0004] 2. There is no automatic tracking system, and each process is counted manually, which is error-prone and inefficient; the production status of components cannot be tracked in real time; manual summarization is carried out every day, and problems cannot be found in time. [0005] 3. Decentr...

AI Technical Summary

Problems solved by technology

[0003] 1. Decentralized control is adopted, each manufacturer has its own control, there is no unified standard, data collection is inconvenient, and it is difficult to realize centralized control of the entire production line; every time the specification is changed, each special machine must be adjusted one by one, which delays time , affecting production efficiency

[0004] 2. There is no automatic tracking system, and each process is counted manually, which is prone to errors and low in efficiency; the production status of components cannot be tracked in real time; manual summary is carried out every day, and problems cannot be found in time

[0005] 3. Decentralized control, point-to-point connection, time-consuming to replace the unit, and error-prone; through terminal block connection, it is easy to loosen and malfunction after a long time

[0006] 4. In the photovoltaic module manufacturing system, there are many devices from different manufacturers, and the standards of each manufacturer are not uniform. In practical applications, they cannot be easily and conveniently placed in the automatic assembly line
