Laboratory gas safety early warning system and method

Abstract

The invention discloses a laboratory gas safety early warning system and method. The system comprises a monitoring center and a detection system arranged in each laboratory, wherein the detection system comprises a control device and a plurality of gas detection devices; the control device comprises a controller, an alarm module and a wireless communication module; the gas detection devices comprise a microprocessor and an acquisition device; the acquisition device comprises a signal acquisition card, a first gas chamber and a closed second gas chamber; a first gas sensor array is arranged inthe first gas chamber; a first gas inlet hole and a gas outlet hole are formed on the first gas chamber; a second gas sensor array is arranged in the second gas chamber; the signal acquisition card isrespectively connected with the first gas sensor array, the second gas sensor array and the microprocessor; and the controller is respectively connected with the microprocessor, the alarm module andthe wireless communication module. The invention has the advantages that the toxic and harmful gas leaked from a laboratory can be timely detected, and an alarm is given, so that the personal safety of operators in the laboratory is guaranteed.

Description

technical field [0001] The invention relates to the technical field of gas safety detection, in particular to a laboratory gas safety early warning system and method. Background technique [0002] The reagents used in chemical experiments in the laboratory usually volatilize some gases, some of which are poisonous and harmful, such as benzene, xylene, formaldehyde, methanol, etc. The above-mentioned gases are usually colorless and transparent gases at room temperature, and have a strong aromatic odor. The above gases can cause poisoning of the central nervous system and other parts of the human body, causing acute or chronic poisoning. In severe cases, headaches, nausea, vomiting, confusion, loss of consciousness, coma, convulsions, etc. will occur. Inhalation of small amounts of the toxic gas can also cause dizziness, rapid heartbeat, headache, and confusion. For example, excessive intake of toluene can cause stomach pain, vomiting, dizziness, convulsions, confusion, rapi...

AI Technical Summary

Problems solved by technology

The above-mentioned toxic and harmful gases are highly volatile and easy to spread in the air, resulting in widespread spread of toxicity and seriously endangering the personal safety of operators in the laboratory environment.
