What benefits does the Internet of Things bring to smart environmental protection applications
Smart environmental protection is an extension of the Internet of Things technology, which puts more emphasis on the application of perception layer technology and intelligence layer technology to realize a real-time and automatic environmental data perception system, and collect and monitor environmental pollution source data and atmospheric environment quality data in real time. industrial iot gateway It can intelligently analyze a large amount of environmental protection monitoring data through powerful computing power, and promote the intelligence and automation of environmental protection work.
The overall structure of "Smart Environmental Protection" is divided into four layers: perception layer, transmission layer, intelligence layer and service layer.
Perception layer: Use any equipment, system or process that can sense, measure, capture and transmit information anytime and anywhere to achieve a "more thorough perception" of environmental factors such as environmental quality, pollution sources, ecology, and radiation;
Transport layer: use environmental protection private network, combined with 4G network, satellite communication and other technologies, to interact and share the environmental information stored in personal electronic devices, organizations and government information systems, to achieve "more comprehensive interconnection";
Intelligence layer: Integrate and analyze massive cross-regional and cross-industry environmental information by means of cloud computing, virtualization, and high-performance computing to realize massive storage, real-time processing, deep mining, and model analysis, and realize "deeper intelligence change";
Service layer: use the cloud service model to establish an object-oriented business application system and information service portal to provide "smarter decision-making" for environmental quality, pollution prevention, ecological protection, radiation management and other businesses.
Specifically, modbus tcp gateway it mainly involves two parts: the front end of the data acquisition hardware and the software system of the background data center. The data acquisition hardware is responsible for collecting on-site environmental data. The environmental data that can be collected include air temperature and humidity, soil temperature and humidity, CO2 concentration, light intensity, ethernet to rs485 converter For water temperature, ammonia nitrogen in water, dissolved oxygen concentration and pH value, etc., the data center summarizes, analyzes, displays and alarms the data through the intelligent analysis software system. When the environmental data exceeds the threshold set by the system, the system will generate an alarm, through sound and light alarm Notify the relevant personnel in the form of devices, mobile phone text messages and pop-up windows, and at the same time start or close the relevant equipment to adjust the on-site environmental indicators. Here 4G wireless transmission plays an important role, generally industrial-grade wireless routers are used as the transmission pipeline at both ends. Therefore, smart environmental protection has high requirements for front-end signal acquisition equipment.
