Laboratory ventilation intelligent PLC system adopting wireless unvarnished transmission mode

Abstract

The invention discloses a laboratory ventilation intelligent PLC system adopting a wireless unvarnished transmission mode, and particularly relates to the technical field of ventilation control systems.The laboratory ventilation intelligent PLC system comprises a PLC control end, the output end of the PLC control end is electrically connected with the input end of a ventilation module, and the output end of the ventilation module is electrically connected with the input end of an environment detection module; and the output end of the database is electrically connected with the input end of an extraction module. According to the PLC system, the extraction module, the statistics module, the voice control module, the environment detection module and the data updating module are arranged, so that the PLC system can update optimal data generated in a network and in the use process of an operator in real time in the actual use process, and the optimal data are screened; the PLC system can perform optimal processing in the shortest time, and the diversified and real-time updated setting can ensure that the PLC system can cope with more and more complex indoor environments, so that the energy consumption is reduced, and the processing effect on the indoor environment is ensured.

Description

technical field [0001] The invention relates to the technical field of ventilation control systems, more specifically, the invention relates to an intelligent PLC system for laboratory ventilation in a wireless transparent transmission mode. Background technique [0002] The laboratory ventilation system is one of the largest and most influential systems in the entire laboratory design and construction process. Whether the ventilation system is perfect or not will directly have an important impact on the laboratory environment, the health of the experimenters, and the operation and maintenance of the experimental equipment. Noxious or pathogenic vapors, gases and particles, laboratory ventilation systems must be able to handle some emergency situations. The fume hood is one of the necessary devices in the ventilation system. The fume hood is a relatively closed cabinet with a certain container space. A movable cabinet door is arranged in front of the cabinet. An operating p...

Problems solved by technology

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a laboratory ventilation intelligent PLC system that adopts wireless transparent transmission. The technical problem to be solved by the present invention is: in the process of actual use, due to the It is changeable, and the contents of experiments in different laboratories are different, which makes it difficult to unify the specific data of ventilation. Therefore, most of the current laboratory ventilation systems usually use manual control. However, its disadvantages are particularly obvious. The gas in the internal laboratory is optimally processed, and it is difficult to perform corresponding processing according to different gases in the laboratory, resulting in the problem that the processing effect is difficult to achieve proportionality to time-consuming and cost
