Fast formaldehyde detection equipment with low power consumption

Abstract

The invention discloses fast formaldehyde detection equipment with low power consumption. The fast formaldehyde detection equipment comprises a formaldehyde detector and intelligent terminal equipment in wireless communication with the formaldehyde detector, wherein the formaldehyde detector comprises an ARM processor, an inspiration control unit, a getter pump, an airflow chamber, an electrochemical sensor, a temperature sensor, a 3G monitoring / alarming unit, a WiFi module, an audible and visual alarm unit and a calibration setting key, the ARM processor controls the inspiration control unit to drive the getter pump to suck air into the airflow chamber, the electrochemical sensor and the temperature sensor are used for acquiring concentration and temperature signals of formaldehyde in the air and transmitting the signals to the ARM processor to calculate the concentration and temperature of formaldehyde after respectively conditioning the signals, the 3G monitoring / alarming unit or the WiFi module transmits the concentration and temperature of formaldehyde to the intelligent terminal equipment in a wireless manner for data storage and analysis processing, and feeds back the concentration and temperature of formaldehyde to the ARM processor, and when the concentration or temperature exceeds the standard, such alarms as short messages and emails are made and the audible and visual alarm unit is controlled to give an alarm. The fast formaldehyde detection equipment disclosed by the invention is used for detecting formaldehyde data quickly and intelligently with high precision and can be used for continuously measuring for a long time.

Description

technical field [0001] The invention relates to the field of formaldehyde gas detection equipment design, in particular to a low-power fast formaldehyde detection equipment. Background technique [0002] Environmental quality testing has always been a major topic of concern in the world. The quality of the environment is directly related to the health of human life and the level of human living standards. Toxic gas detection is a crucial part of environmental detection. Formaldehyde is a colorless gas with a strong pungent odor. Soluble in water, alcohol and ether. Formaldehyde is harmful to human health mainly in the following aspects: [0003] a. Stimulation: The main hazard of formaldehyde is the stimulation of the skin and mucous membranes. Formaldehyde is a toxic substance in the plasma, which can be combined with proteins. When inhaled at high concentrations, severe respiratory tract irritation, edema, eye irritation, and headache will occur. [0004] b. Sensitiza...

Problems solved by technology

[0007] These methods all require long-term sampling on site, and the measurement results are one-hour average values. The analysis cycle is long, the operation is cumbersome, the detector is expensive, the detection accuracy is low, and it is susceptible to external interference, and it cannot continuously observe the dynamic changes of the data.
