Air Conditioning Automatic Control System in Infusion Pharmacy Workshop

Abstract

The invention aims to provide an air conditioning automatic control system of infusion pharmaceutical workshops. A programmable logic controller (PLC) control box is additionally provided, and a medicine liquid pump serving as a signal source transmits a signal to the PLC control box, so that a controller is controlled within the corresponding workshop section time period to turn on and turn off a third air conditioning fan; a main control box is controlled by a work signal of the third air conditioning fan to control a first air conditioning fan and a second air conditioning fan, and the first air conditioning fan and the second air conditioning fan operate in a high-frequency state during normal production and then switch to a low-frequency state to operate after production is finished, so that energy-saving and consumption-reducing aims are fulfilled; the air conditioning fans in three workshops can be control well; and the operating efficiency of equipment is improved, the labor intensity of workers is reduced, the occurrence probability of artificial deviation is reduced, and the operating safety of the equipment is improved.

Description

technical field [0001] The invention relates to the field of air-conditioning control in workshops, in particular to an automatic air-conditioning control system in a transfusion pharmaceutical workshop. Background technique [0002] The current large infusion clean production area is divided into three levels, which are controlled by different air conditioning systems. The controller of the first air-conditioning fan is in the dilution room, while the controllers of the other two air-conditioning fans are in the production area. During normal production, the air-conditioning fans in the third-level area normally operate at high frequency. But after the end of the night shift, the first air-conditioning fan can be turned off (this is manually operated by rare personnel). The air-conditioning fans in the other two areas can also be adjusted to operate at a suitable low frequency, so as to achieve the purpose of saving energy and reducing consumption. The following problems...

AI Technical Summary

Problems solved by technology

The following problems exist in the existing air-conditioning system: the first air-conditioning fan is manually operated by sparsely allocated personnel. If the air-conditioning system is not turned on in time at the beginning of production, the infusion product cannot be produced in the specified process environment, thereby causing infusion products Bring great quality risks

After the evening shift production, if the first air-conditioning fan is not turned off in time, it will cause a great waste of energy; because the air-conditioning control systems of the other two areas are in the general production area, the operation is very inconvenient, and professional Manual control by personnel, serious safety problems will occur if improper operation
