Monitored Control System Of Environment

Today, in the context of the rapid development of the global economy, although people’s concept of smart home is continually changing, the requirements of quality and safety of the living environment are higher and higher. Most of the smart home products can only achieve very little function, so in order to meet the requirements of multiple parameter monitoring and controlling and then monitored control system of environment was designed.As a part of the intelligent building, based on single-chip microcomputer technology and wireless communication as the core, and using of detection technologies, sensor technologies and system integration technology, the system realizes real-time monitoring and control on indoor air quality, humidity, temperature, the concentration of carbon monoxide, fire hazards and indoor security. Monitored control system of environment is divided into three parts, namely environmental monitoring unit, control unit and data center. The function of environmental monitoring is to monitor a variety of factors of the indoor environment.The function of control unit is alarm that exceeds the set value and ventilate the high concentration of toxic gas to reach the goal of improving air quality. The function of data center is that all data collected wirelessly are sent to PC in order to display and control.The system adopts modularization design. By using it, we can shorten the system development time and the system is also easy to debug, install. Environmental monitoring unit, control unit and the data center contain uniform common module. The common modules are consist of power supply, wireless communication and main control CPU board. Wireless communication adopts NRF24L01+chips and designs a non-standard protocol. Main control CPU board is based on Texas Instruments’ MSP430F149.
