Formaldehyde gas detection system

Abstract

The invention discloses a formaldehyde gas detection system and relates to the technical field of gas detection. The detection system comprises a distributed formaldehyde concentration detection module, a remote control switch, a communication module and terminal equipment, wherein the distributed formaldehyde concentration detection module comprises a plurality of formaldehyde sensors which are detachably distributed in the to-be-detected area; the terminal equipment comprises a terminal controller, a data processor, a data memory, a display, a counter and an alarm device; the remote controlswitch is in control connection with the formaldehyde sensor; the remote control switch is electrically connected with the terminal controller through the communication module; the formaldehyde sensortransmits data information to the data processor through the communication module, and the data information is then stored in the data memory; and the display is used for displaying and independentlydisplaying the data information from the data memory corresponding to each formaldehyde sensor. The system can be used for detecting the formaldehyde concentration of residences in multiple directions at the same time, and accordingly detection errors can be reduced.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a formaldehyde gas detection system. Background technique [0002] Formaldehyde is a colorless and irritating gas. Long-term exposure to formaldehyde can reduce the respiratory function of the body, the information integration function of the nervous system and affect the immune response of the body. Also has toxic effects. [0003] Before people move into a new living environment, they generally need to test the formaldehyde content of the living environment to see if it exceeds the standard, so as to judge whether it is suitable for living. Most of the existing formaldehyde detectors are small desktop or hand-held single instruments, which mainly have the following problems. They can only detect the concentration of formaldehyde gas in the surrounding area, and are not suitable for large-area area detection. For example, for large-area In residential buildings, the dete...

Problems solved by technology

Most of the existing formaldehyde detectors are small desktop or hand-held single instruments, which mainly have the following problems. They can only detect the concentration of formaldehyde gas in the surrounding area, and are not suitable for large-area area detection. For example, for large-area In residential buildings, the detection results can only represent the instantaneous concentration, while the indoor formaldehyde concentration often changes with time, and is more affected by indoor personnel activities. The instantaneous detection concentration often cannot accurately reflect the indoor formaldehyde concentration, and there is a problem of detection deviation. Therefore, there is room for improvement
