Monitoring system and monitoring method

The invention relates to the technical field of solar energy. Provided are a monitoring system and a monitoring method. The monitoring system includes a monitoring center, N data transmission systemseach in communication with the monitoring center, and N data control systems each in communication with the monitoring center, with the N data control systems corresponding one-to-one to the N data transmission systems. With the monitoring system, it is possible to monitor, at anytime and anywhere, the project service and operation conditions of N solar systems arranged at different locations, timely acquire the real-time operation information of the N solar system monitoring devices arranged at different locations, and conduct, according to such information, remote and centralized control over the solar system monitoring devices. The monitoring system enhances the controllability of the solar system monitoring devices, saves and reduces the maintenance costs, improves the scientific management level, and also has
