Mobile terminal with harmful substance detection system and harmful substance detection method

Abstract

The invention discloses a mobile terminal with a harmful substance detection system. The mobile terminal is provided with a display screen, wherein a ventilating hole is formed in the mobile terminal; the harmful substance detection system comprises an integrated sensor module, an analog / digital (A / D) conversion module, a data analysis processing module and a result output module which are electrically connected with a central control module respectively; the central control module controls the working mode of the system; the ventilating hole is connected with the integrated sensor module; the integrated sensor module detects harmful substances entering from the ventilating hole and generates an analog signal; the analog signal is converted into a digital signal through the A / D conversion module and transmitted to the data analysis processing module for analysis, and detection result information is generated and sent to the result output module; and the result output module transmits the detection result information to the display screen of the mobile terminal for displaying. The invention also provides a harmful substance detection method. The mobile terminal is easy to operate and convenient to carry.

Description

technical field [0001] The invention relates to a harmful substance detection system and method, in particular to a mobile terminal with a harmful substance detection system and a harmful substance detection method. Background technique [0002] With the development of industry, the extensive use of various chemical substances and pesticides has filled people's lives with various harmful substances, and is increasingly threatening people's health. Both food and living environment are full of various substances harmful to the human body, for example, fruits and vegetables have pesticide residues that are harmful to the human body, the indoor environment has harmful formaldehyde gases brought by decoration and furniture, and the outdoor environment has various industrial waste gases and automobile exhaust, etc., so that people in the process of life Unknowingly, they passively absorb harmful substances. Although there are a large number of devices that can detect harmful subst...

AI Technical Summary

Problems solved by technology

[0003] First, the existing devices are complicated to operate, and most of them require professional technicians to operate, which is inconvenient and impractical for general non-professional users;

[0004] Second, the existing devices are inconvenient to carry and cannot provide services to users in time;

[0005] Third, most of the existing devices are unitary and can only detect the same type of harmful substances, which cannot effectively meet the needs of users for various occasions

[0006] With the rapid development and progress of social science and technology, mobile terminals appear in every corner of people's lives, but there is no mobile terminal that can provide the detection function of harmful substances under the existing technology
