The fan 300, the air conditioner are associated with the VOC sensor, combustible gas sensor, temperature sensor, and humidity sensor. The automatic fire sprinkler is associated with the smoke sensor and temperature sensor. When it is detected that the concentration of volatile organic compounds, combustible gas, etc. in the box 100 exceeds the preset threshold, the terminal can control the exhaust fan 300 to operate; when it is detected that the temperature and humidity in the box 100 exceed the preset threshold, the terminal controls the air conditioner to operate to control the temperature and humidity in the box 100 within an appropriate range; when it is detected that there is smoke and the temperature exceeds the preset threshold, the automatic fire sprinkler starts to extinguish the fire and sends an alarm prompt. The automatic fire sprinkler is preferably filled with heptafluoropropane fire extinguishing agent. Through the above sensors and equipment, intelligent linkage control is realized, which is convenient for the management of hazardous waste and is safer and more reliable.

[0069] Optionally, a liquid level sensor electrically connected to the terminal is provided in the collection box 200. When the detection value of the liquid level sensor exceeds the set safety threshold range, the terminal or the Internet of Things cloud platform gives a warning or alarm prompt through the alarm, and the Internet of Things cloud platform records and stores the warning and alarm information.
