Multi-parameter wireless real-time monitoring and alarming system suitable for clean operating room air environment

The invention discloses a multi-parameter multi-point wireless real-time monitoring and alarming system suitable for a clean operating room. The system is mainly composed of a data collection unit, aZigBee wireless router, an executing mechanism and an upper computer. The data collection unit comprises a temperature and humidity sensor, a wind speed sensor, an oxygen sensor, a particulate mattersensor, a carbon dioxide sensor, a microorganism sensor, a human body infrared sensor, a battery, a sound-light alarm, a single-chip microcomputer MCU and a ZigBee wireless module. The system can conduct multi-point wireless monitoring on indoor air temperature and humidity, wind speed, oxygen, particulate matter, carbon dioxide and microorganism concentration in the clean operating room in real time on the basis that the normal operation process is not disturbed. When one concentration exceeds the standard, the system can give an alarm in time and feed the concentration back to a central airconditioner system for adju
