Background

When the oil product is operated in the production areas of oil product storage, transportation, refining and sale enterprises, the air quality of the operation site is detected, and the oil product can enter after meeting the national safety standard. Since the gas concentration in the hazardous location is a potential hazard factor, it is invisible and untouchable. In order to ensure the life safety of the worker, the worker must follow the principle of "first check and then work", and must be prohibited from entering the work site until the air quality is not confirmed. When the operation is carried out in a dangerous place, the concentrations of oxygen, harmful gases, combustible gases and dust are measured in advance according to actual conditions, and the safety requirements of national standards are required to be met. When the concentration of oxygen, toxic and harmful gas, combustible gas and dust may change greatly, the concentration should be measured regularly or continuously. During operation, the on-site guardian needs to monitor the position in place, so that the safety and health of the operator entering a dangerous place are guaranteed. When oxygen deficiency and poisoning symptoms occur in the operation process or the detection instrument gives an alarm, the operation must be stopped immediately, personnel at an operation point should leave the operation site quickly, and rescue personnel immediately organize emergency treatment and medical treatment in a safe area.

At present, the air in dangerous environment and closed space is generally detected through a four-in-one gas detector, and the detector can simultaneously detect the following four gases: combustible gas, O₂CO and H₂S, the application occasions are combustible gas environments, limited spaces, leakage, oxygen-deficient and toxic gas environments. When the gas concentration exceeds the safety range, the four-in-one gas detector can give an alarm to remind constructors of evacuating. In order to ensure the safety of the working environment, the detection personnel detect whether the gas concentration of the working site meets the national regulations every two hours.

However, in actual work, the operator may cause leakage of toxic gas and flammable gas due to improper operation, negligence of work, etc., which may cause a sharp increase of gas concentration in the working environment, and the detector may not find the gas concentration in time because the detector detects the gas once in two hours instead of real-time detection, thereby threatening the personal safety of the constructor, and the reliability is low. When the detector is used, detection personnel must hold the detector to carry out mobile detection, and the efficiency is low.
