Disclosed is a remote real-time monitoring system based on cloud computing, including a monitored end, i.e. a terminal collecting data and performing control on site, a management end, i.e. a user terminal performing remote monitoring and management on the monitored end, and a cloud monitoring platform. The monitored end and the management end are connected to the cloud monitoring platform through a network including but not limited to GPRS, 3G, broadcast TV network, telecom network, power carrier network, satellite, etc. via the Internet. A monitoring service system running on the cloud monitoring system stores, analyses and computes the data sent by the monitored end. A fault diagnosis system, a report analysis system and so on are also mounted to monitor the state of the monitored end and pre-warn of a fault and so on in real time. The present invention makes the monitored end and the management end form a real-time monitoring internetwork through cloud service and cloud computing, and the system can be applied with low costs, high reliability, convenient and simple use.
