Abstract: A remote real-time monitoring system based on cloud computing is disclosed, comprising: a monitored terminal which is a terminal for collecting data and processing control on site, a management terminal which is a user terminal for performing remote monitoring and managing on the monitored terminal, and a cloud monitoring platform. The monitored terminal and the management terminal are connected to the cloud monitoring platform through a network comprising GPRS, 3G broadcast TV network, telecommunication network, power carrier network and satellite via the Internet. A monitoring service system operated on the cloud monitoring platform stores, analyzes and computes data sent by the monitored terminal. A monitoring service system, a fault diagnosis system and a report analysis system and etc. are also mounted to monitor states of the monitored terminal and pre-warn a fault in real time.
