Implementing the data acquisition and monitoring system is beneficial to improving the application efficiency of the entire enterprise information system. Currently, there are three types of data acquisition and monitoring systems based on telephone lines, network transmission, and embedded systems. In the future, the data acquisition and monitoring system using the Internet as the communication carrier is becoming the mainstream of the era.

[0003] For the data acquisition and monitoring system in photovoltaic glass production, the current line control system controller of the photovoltaic glass cold end production line uses Siemens S7-300PLC, and the upper computer software uses Siemens WINCC software. Each production line is equipped with three sheet unloading manipulators and a cutting system. The control system of the sheet unloading manipulator is controlled by Siemens S7-1500PLC. PROFIBUS DP communication is used for data transmission between the line control PLC, the cutting system, the PLCs of each manipulator control system, and each manipulator controller. The upper computer and the PLC on each line communicate through the MPI network. The upper computer is independently set and there is no backup. When the upper industrial computer fails, it can only be replaced or repaired, which will bring great inconvenience to production, and the repair of the faulty industrial computer will be very urgent.

The failure of any upper industrial computer will not affect the safe production operation of each production line, and the repair time of the faulty industrial computer is sufficient; the line control system of each photovoltaic glass cold end production line is aggregated from independent systems into a large system, which provides convenience for the workshop production line-level data acquisition during the promotion process of the enterprise digital factory and can reduce a large amount of data acquisition work.
