PROBLEM TO BE SOLVED: To provide a cloud general-purpose environmental information monitoring system and its middleware for keeping damages due to natural disasters to a minimum in business types, such as types represented by agriculture industry and fishery and aquaculture industry in which yields are substantially affected by natural phenomena, and types like river management.SOLUTION: A cloud general-purpose environmental information monitoring system has a multi-hop communication function that, by making middleware lie in between, reads supply voltage corresponding to each sensor and various settings of communication formats from a server, enables communication with each sensor, and is easy to add and change analog and digital communication-type sensors according to environmental information corresponding to a purpose. The system does not need an external power source because it includes a photovoltaic power generator. The system obtains environmental information obtained by an environmental information acquisition sensor node capable of continuous data transmission, transmits it to the cloud server through a mobile phone network or the Internet, and integrally manages the collected environmental information.SELECTED DRAWING: Figure 1 |
