Abstract

The invention discloses a water distiller monitoring system based on a Profibus. The water distiller monitoring system comprises a monitoring center upper computer installed with industrial control configuration software, a Profibus / RS232 conversion module, the Profibus, a plurality of Profibus control terminals for carrying out field data acquisition and control on a water distiller and a signal acquisition device and an execution mechanism device which are connected with the Profibus control terminals respectively, the Profibus control terminals comprise controllers, signal conditioning circuits, data acquisition circuits, data merge processors, photoelectric couplers, Profibus transceivers and electromagnetic valve driving circuits. The water distiller monitoring system is simple in structure, reasonable in design and high in automation degree and works to carry out comprehensive and real-time monitoring on a distilled water production process to fundamentally guarantee the distilled water production quality and reduce the operation cost.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a field bus-based distilled water machine monitoring system. Background technique [0002] High-efficiency distilled water machines for medicine are indispensable equipment in every pharmaceutical industry. With the rapid development of my country's pharmaceutical industry, the demand for distilled water machines, the basic production equipment, is also expanding. As distilled water is the basic water for injection in the pharmaceutical industry, its quality The significance of is self-evident. However, judging from the current level of domestic pharmaceutical production development, the production process, technical equipment, production environment, and quality control of most pharmaceutical factories do not meet the requirements. [0003] The mathematical model of the distilled water machine is relatively complex, and its heat exchange circuit is closely related to the main steam pressur...
