ABSTRACT

The ventilation design of PCR laboratory is the premise of ensuring the reliability, accuracy and safety of the experiment. In the architectural layout, the PCR laboratory should be divided into reasonable areas, the pressure gradient between each laboratory room should be strictly controlled, and the purification and adjustment system and sterilization device should be set up. The structure of BP neural network decoupler and neuron adaptive PID controller are designed, and the initial value of the controller weight is determined by the parameters of traditional PID control algorithm. The simulation results show that the proposed control scheme can complete the decoupling and control tasks of the system well, and can improve the control law by learning in the control process, which has good decoupling and robustness. When the indoor air supply state is not changed, the best air change frequency of this PCR nucleic acid detection laboratory is 22 times/h; When changing the indoor air supply state, the best air exchange rate of this PCR nucleic acid detection laboratory is 18 times/h, which is lower than the air exchange rate required by the code. It can run stably and save energy.
