Based on the Internet of things, big data, cloud computing and other modern information technologies, arcrui cloud platform connects the distributed automatic fire alarm equipment, electrical fire monitoring equipment, intelligent smoke detector, safe electricity and water and other equipment to form a network, and intelligently perceives, identifies and locates the status of these equipment, dynamically collects fire information in real time, and communicates with the public Through the cloud platform for data analysis, mining and trend analysis, it helps to achieve the goals of scientific early warning of fire, grid management, and implementation of multiple responsibility supervision. It fills the gap that the original "nine small places" and hazardous chemical production enterprises can not effectively monitor, adapts to all public and civil buildings, realizes the unattended safe electricity use, and realizes the actual needs of "automation", "intelligence", "systematization" of safe electricity use and "refinement" of electricity use management.
