Hazardous chemical gas detection terahertz safety door and detection method

Abstract

The invention relates to the field of laboratory hazardous chemical gas safety protection equipment, in particular to a hazardous chemical gas detection terahertz safety door and a detection method. The terahertz safety door comprises a terahertz wave transmission probe, a terahertz wave modulator, a terahertz wave receiving probe, a terahertz wave receiving processor, a central processing unit, an electronic door lock and a buzzer. The invention utilizes the characteristics that a terahertz spectrum of gas cintains rich physical and chemical information to establish a huge hazardous gas terahertz spectrum information base, and real-time comparison is carried out so as to solve the problems of insufficient induction type and low sensitivity of existing hazardous gas detection devices. The terahertz safety door provided by the invention adopts a design of combining the central processing unit with the electronic door lock and the alarm buzzer, when indoor hazardous gas exceeds the standard, the safety door controls opening of the electronic door lock at first time, the door is bounced off, so that outdoor air can enter a room to reduce the concentration of indoor hazardous gas, also ringing of the alarm buzzer is controlled at the same time to give a warn to people indoors visually, thus reducing the probability of risks.

Description

technical field [0001] The invention relates to the field of laboratory dangerous chemical gas safety protection equipment, in particular to a dangerous chemical gas detection terahertz safety door and a detection method. Background technique [0002] While China is gradually entering into industrialization, industrial accidents that occur in China every year are also occurring frequently. Coal mine explosions, factory fires, worker poisoning, and other such news reports emerged one after another. The occurrence of these accidents is mainly caused by improper use of flammable, explosive, toxic and harmful gases in industrial environments. As the name implies, a gas alarm is a gas leak detection and alarm instrument. When flammable or toxic gas leaks in the industrial environment, when the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the alarm will send out an alarm signal to remind the work to take safety ...
