Abstract
Objective To study the remote monitoring and automatic control system of biological safety level 3 laboratory, the core of which is the configuration software and PLC. Methods According to the special requirements of biological safety level 3 laboratory, which included keeping a stable laboratory negative pressure, maintaining negative pressure gradient and directional flow between different areas and the system switch and transformation of different working conditions (normal working mode, disinfection mode and unattended mode), airflow regulation was combined with differential pressure regulation in the system. The variable-air-volume valve for air supply was controlled based on the number of the safety cabinets in operation, the frequency of the converter was based on the pressures in the header pipes for air supply and exhausting, and the variable—air-volume valve for air exhausting was based on the differential pressure in the room. Results The requirements of biological safety level 3 laboratory and the new specification were satisfied. Conclusion Siemens Win CC configuration software and S7—300PLC are used for data acquisition and automatic control in the system, and the trial in some biological safety level 3 laboratory of Chinese CDC proves the stability and reliability.关键词
