Safety monitoring and early warning system for laboratory

Abstract

The invention discloses a safety monitoring and early warning system for a laboratory. The system includes a laboratory body, identity authentication modules, and an experiment table. The laboratory body is divided into a general experimental area and a special experimental area; each of the identity authentication modules includes a fingerprint entry unit, a user database, and a processing unit;the experiment table includes a reagent platform, a monitoring unit, and an early warning unit; an early warning database and an alarm are disposed in the early warning unit; a combination mode of experimental reagents that are dangerous is stored in the early warning database; when any one of the experimental reagents in dangerous experimental reagent combination contained in the early warning database is taken and utilized, the monitoring unit controls and restricts access of other experimental reagents that are in the same dangerous experimental reagent combination with the taken experimental reagents; and the alarm is connected to a sensing module and gives an alarm when the experimental reagents that are restricted to be taken are taken. The system can limit the access of the experimental reagents mixed with danger, avoids the occurrence of the danger, and timely emits warnings when potential dangers occur to ensure the safety of personnel and property.

Description

technical field [0001] The invention relates to the technical field of laboratory safety, in particular to a laboratory safety monitoring and early warning system. Background technique [0002] Chemistry is a kind of natural science. It studies the composition, properties, structure and change laws of substances at the molecular and atomic levels; the science of creating new substances. The chemical laboratory is an important place to provide chemical experiment conditions and conduct scientific research. There are a large number of instruments: iron stand, asbestos net, alcohol lamp, beaker, test tube, gas collecting bottle, rubber stopper, reagent bottle, mortar and other experimental tools, usually equipped with a chemical cabinet, which contains commonly used chemical Medicines, such as: copper sulfate pentahydrate, sodium hydroxide solution, limestone, hydrochloric acid, etc. The reaction phenomenon between various experimental reagents in chemical experiments looks int...

[0002] Chemistry is a kind of natural science. It studies the composition, properties, structure and change laws of substances at the molecular and atomic levels; the science of creating new substances. The chemical laboratory is an important place to provide chemical experiment conditions and conduct scientific research. There are a large number of instruments: iron stand, asbestos net, alcohol lamp, beaker, test tube, gas collecting bottle, rubber stopper, reagent bottle, mortar and other experimental tools, usually equipped with a chemical cabinet, which contains commonly used chemical Medicines, such as: copper sulfate pentahydrate, sodium hydroxide solution, limestone, hydrochloric acid, etc. The reaction phenomenon between various experimental reagents in chemical experiments looks interesting and magical, but the reaction between some chemical reagents will cause release Toxic gas, sudden increase / decrease in temperature, and serious consequences such as explosion, so it is necessary to have a certain understanding of the interaction between reagents when conducting experiments. For some personnel with insufficient chemical knowledge, blindly doing experiments is likely to cause serious damage Therefore, it is necessary to carry out certain safety monitoring on the process of chemical experiments, and to issue early warnings in time before dangers occur, so as to ensure the safety of personnel.
