Environment safety control system based on multimedia classroom

The invention discloses an environment safety control system based on a multimedia classroom. The system comprises a monitoring module, a control module, a wireless communication connection module anda fresh air module, and is characterized in that the monitoring module comprises a temperature and humidity sensor, a carbon dioxide concentration sensor, a CCD camera module, a light sensation sensor and a P.M2.5 monitoring sensor, and the control module is designed based on an STM32F105 single chip microcomputer. Two CAN interfaces are integrated at one end of the STM32F105 single chip microcomputer, PIC single chip microcomputer design is adopted in the wireless communication connection module, meanwhile, a ZigBee wireless receiving and transmitting module is welded and integrated in the PIC single chip microcomputer, and the fresh air module comprises an air conditioner, exhaust equipment and a fan. According to the environment safety control system, the STM32F105 single chip microcomputer and the PIC single chip microcomputer are designed to form a complete embedded control system, the monitoring sensitivity is improved, a large number of ZigBee wireless technologies are used, emergencies are avoided, the environment safety coefficient of the classroom is improved, comfortable learning environment is provided, and the learning requirements of teachers and students are met.
