An emergent wireless toxic gas indicator for chemicals leakage accident

Abstract

The invention relates to an emergency wireless toxic gas detector for chemical leakage accident, which belongs to a field of safe production monitoring and emergency rescue technology. The detector comprises a wind direction and wind speed sensor, at least one toxic gas sensor and an amplification circuit thereof, a single-chip and a peripheral circuit thereof, a GPS module, a wireless sending module and an antenna thereof, an ID setting switch, a power supply, and a power switching circuit. The output terminal of each toxic gas sensor is connected with the input terminal of amplifying circuit thereof, the output terminal of each amplifying circuit is connected with an AD switching interface of the single-chip, wind speed and wind direction output ports of the wind direction and wind speed sensor are respectively connected with the single-chop, the GPS module, the wireless sending module and the power switching circuit are respectively connected with the single chip, and the power supply is connected with the power switching circuit. The invention can detect wind direction and wind speed, and concentration of multiple toxic gases in emergency rescue field of the chemical leakage accident, and send the detected result timely to remote end emergency command center so as to guarantee public life and property safety.

Description

technical field [0001] The invention belongs to the technical field of safety production monitoring and emergency rescue, and in particular relates to a gas detector for detecting wind direction, wind speed and toxic gas concentration at the site of a chemical leakage accident, and automatically sending the information to an emergency rescue command center through wireless. technical background [0002] With the development of the petrochemical industry, the types and application ranges of flammable, explosive and toxic gases have been increased. Once these gases leak during production, transportation, and use, it will cause poisoning, fire and even explosion accidents, seriously endangering people's lives and property safety. Due to the diffusibility of the gas itself, after leakage, the gas will spread along the ground surface under the action of external wind force and internal concentration gradient, forming a combustion explosion or poisonous danger zone at the accident...

AI Technical Summary

Problems solved by technology

However, although there are currently portable detection equipment for gas concentration monitoring, most of them can only detect a single gas, and the composite detection equipment for monitoring the wind direction, wind speed and concentration of various gases at the scene of chemical leakage accidents is basically in a blank state. After the accident, it is impossible to obtain the relevant information of the accident scene in time, which seriously affects the smooth development of emergency rescue work and easily causes heavy property losses and casualties.
