Description

technical field [0001] The invention relates to the technical field of data measurement and monitoring in the process of boiling sugar crystallization, in particular to a data monitoring method and system for boiling sugar crystallization. Background technique [0002] At present, the functions and structures of the automatic control system used in the sugar boiling and crystallization process are basically the same, and can be roughly divided into four parts: data acquisition, data display, data processing and actuators. The idea of ​​constructing the automatic control system of the sugar crystallization process is: firstly, obtain the real-time state parameters of the sugar crystallization process (such as vacuum degree, massecuite temperature, liquid level, steam temperature, steam pressure, massecuite hammer, etc.) through various hardware sensors. State parameters), and then transmitted to the host computer monitoring system through the field bus, after the host compute...
