Abstract

The invention discloses a portable classroom environment monitoring device. The monitoring device comprises a controller and a multipath data selector. A voltage / frequency converter and an address switch circuit are arranged in a housing. A display and a light intensity are fixed on the front part of the housing. A temperature-humidity integration sensor and a CO2 sensor are fixed on the upper part of the housing. A port device is fixed on the side part of the housing. A noise detection device and an air pressure sensor are fixed on the lower part of the housing. A CO2 sensor and a noise detection device are connected with the multipath data selector. The multipath data selector is connected with the voltage / frequency converter and the controller. The voltage / frequency converter is connected with the controller. The controller is connected with the display, the temperature-humidity integration sensor, the air pressure sensor, the light intensity sensor, the address switch circuit and the port device. According to the invention, various kinds of data can be monitored in real time; and the monitoring device is quite small in size, portable and easy to install.

Description

technical field [0001] The invention relates to a portable classroom environment monitoring device, which belongs to the technical field of monitoring devices. Background technique [0002] The total population of various schools (universities, middle schools, primary schools and kindergartens) in our country is about 300 million, and the classroom environment plays a very important role in the physical and mental health of these students. On June 9, 2008, the Ministry of Education and the Ministry of Health jointly promulgated the "National Basic Standards for School Physical Education and Hygienic Conditions" and "Sanitary Standards for Primary and Secondary School Classroom Ventilation" (GB / T17226); on October 5, 2008, the National Quality Supervision and Inspection The General Administration of Quarantine and the State Environmental Protection Administration of the Ministry of Health jointly promulgated the "Indoor Air Quality Standard" (GB / T18883-2002); the Ministry of ...
