A laboratory safety monitoring system and method based on the Internet of Things

Abstract

A laboratory safety monitoring system and method based on Internet of Things are disclosed. The system includes a background server and a monitoring device disposed in a laboratory. The monitoring device includes a control device and a harmful toxic gas detection device. The harmful toxic gas detection device includes a plurality of gas detection modules disposed at different positions of the roofof the laboratory. The gas detection modules include bases. The lower surfaces of the bases are provided with a plurality of gas sensors forming a round shape and equally spaced along the round shape. The bases are also provided with microprocessors and first wireless communication modules. The control device includes a controller, an alarm module and a second wireless communication module. The microprocessors are electrically connected to the gas sensors and the first wireless communication modules respectively. The controller is electrically connected to the alarm module and the second wireless communication module separately. Safety of a laboratory can be effectively monitored through the system and the method, and when leakage of harmful toxic gas is detected in the laboratory, an alarm is given in time.

Description

technical field [0001] The invention relates to the technical field of laboratory safety monitoring, in particular to a laboratory safety monitoring system and method based on the Internet of Things. Background technique [0002] During chemical reactions, many harmful gases are often produced, such as hydrogen, carbon monoxide, carbon dioxide, methane, toluene, etc. The harmful gases generated after these chemical reactions are harmful to the human body, toxic or flammable and explosive. In the chemical laboratory, if the toxic, harmful, flammable and explosive gas leaks after the reaction, it will endanger the personal safety of the experimenters. Therefore, early detection, early forecast, and timely and secure solution to the leakage problem can maximize To ensure the safety of the laboratory to a certain extent. Contents of the invention [0003] In order to solve the above problems, the present invention provides a laboratory safety monitoring system and method base...
