Various detectors installed in various environmental scenarios (parks, buildings, lakes, rivers, etc.) can detect information (temperature, humidity, air quality, water level, etc.) .The terminal nodes based on the LoRaWAN protocol can transfer the information collected by the detector to LoRa Gateway, such information will establish communication with the cloud center through the processor, When the collected data changes, the system starts the data reporting service. Each detector will have a unique ID to identify. All terminal nodes in each scene will have a unique ID to identify different scenarios.
System main function：
(1) Data collection:
Environment data will be transferred to the cloud center through the wireless network for intelligent analysis and processing.
(2) Data storage
The system store the historical data and thus form a knowledge base, ready for processing and query.
(3) Data analysis
Data collected by the system will be send to the user in a intuitive form to show the time distribution (line graph) and spatial distribution (field map), to provide daily reports, monthly reports and other historical statements.
(4) Unified certification
System set up unified authentication, centralized management and control, including user management, equipment management, certification management, rights management and other functions.
(5) Mobile phone surveillance
4G mobile phone can achieve the same function as the computer terminal, real-time view of all data transferred from the detector.
3. System Advantage
Wireless network work in the 470MHz band, green, environmentally friendly, no radiation sensor network features a whole network synchronization of ultra-low power consumption, wireless collection terminal using two alkaline batteries can work more than 3 years; network automatic load balancing, all the wireless nodes power consumption can be assessed, similar power consumption nodes automatically group a network, self-maintenance, visual network connection. Full-time stable operation without human intervention. Users can conduct all the supervisory control by accessing directly to the gateway or network server. The management software has a good interface and powerful function to ensure a timely and accurate data record or analysis. Stable and reliable wireless sensor network work independently without paying any fees, multi-collector data send through a designated gateway, thus greatly save 4G traffic data cost.
