When necessary, the control server needs to adjust the indoor air exhaust volume of the laboratory air environment monitoring system to ensure that the laboratory still needs to maintain a negative pressure state (to ensure that toxic, harmful and irritant substances in the laboratory air do not overflow); in addition, the set temperature and humidity of the laboratory can be maintained.
When the smoke sensor collects that the indoor smoke concentration is greater than a threshold value, for example, the fire smoke sensor generally alarms when the fire smoke concentration reaches 0.65-15.5% FT concentration, the standard of the laboratory can be properly improved, for example, the threshold value is set to be 0.6% FT; the control server controls the laboratory air environment monitoring system to execute air exhaust operation; the infrared temperature sensors are respectively arranged in corresponding monitoring areas and used for monitoring indoor temperature and sending the indoor temperature to the control server; when the indoor temperature is monitored to be higher than the ignition temperature (such as 200 degrees centigrade) and the indoor smoke concentration is monitored to be higher than the threshold value, the control server controls the fire-fighting water spraying equipment or the gas fire-fighting equipment to perform fire extinguishing operation. In specific implementation, the corresponding fire fighting equipment can be selected according to the use standard of a laboratory. The fire-fighting monitoring system is associated with the laboratory air environment monitoring system, and the intelligent requirement of a laboratory is further met.

If the severity of the accident is continuously monitored to be enlarged, the control server forcibly turns off the air supply equipment and simultaneously increases the treatment power of the treatment equipment and controls the intelligent lighting control system and the fire-fighting monitoring system subsequently until the crisis is resolved or the corresponding authorized person relieves the system or the system is damaged.
