Indoor environment monitoring system

Abstract

The invention discloses an indoor environment monitoring system. In the system, the outputs of a CO sensor circuit, a SO2 sensor circuit, a CH2O sensor circuit, a CO2 sensor circuit, a noise sensor circuit and an electromagnetic radiation sensor circuit are connected with the input of a sensor multipath gating circuit, the output of the sensor multipath gating circuit is connected with the input of an analog-to-digital conversion circuit, the outputs of the analog-to-digital conversion circuit, a temperature-humidity sensor circuit, an inhalable particulate sensor circuit, a reserved interface circuit and a key circuit are respectively connected with the input of a singlechip, the output of the singlechip is respectively connected with an acousto-optic alarm circuit, a liquid crystal display circuit and a reserved expansion I / O port circuit, and a power supply circuit supplies power for the whole system. The system can monitor eight environment pollution-related parameters, intelligently analyze the influences of each parameter on a human body, display a current comfortableness value, and automatically execute relevant operations according to data results, and has convenient operation, high automation degree, high correctness and good safety.

Description

technical field [0001] The invention relates to an environment monitoring system, in particular to an indoor environment monitoring system for large buildings and ordinary families. Background technique [0002] Buildings, such as buildings and residential buildings, have a direct and important impact on the internal environment of people's physical and mental health. The indoor air quality standard (GB / T188883-2002) promulgated by our country has made relatively strict regulations on the indoor environment. People spend more than 85% of their time indoors, and the quality of the indoor environment is very important to people's physical and mental health. At present, the monitoring of the indoor environment mainly depends on the monitoring of the environmental indicators of the specific environment within a certain period of time by technicians, and the real-time performance is poor. However, the existing monitors can only monitor content, and the degree of automation is no...

Problems solved by technology

At present, the monitoring of the indoor environment mainly depends on the monitoring of the environmental indicators of the specific environment within a certain period of time by technicians, and the real-time performance is poor.

However, the existing monitors can only monitor content, and the degree of automation is not high. They cannot predict and alarm harmful events, nor can they display the current environmental comfort, and they cannot automatically perform relevant operations based on the measured data. requirements
