The invention relates to an intelligent monitoring system for a boiler and a heat exchange station and a method thereof, which belong to the technical fields of production monitoring and security management. The system comprises a main system in a central control room, a plurality of boiler monitoring subsystems which are respectively connected with the main system in the central control room and a plurality of heat exchange station monitoring subsystems. The method comprises the following steps: parameters and video signals on site are collected and transmitted in real time and transmitted to a host machine in the central control room after being converted and compressed; the host machine carries out comprehensive processes of intelligent analysis, dynamic display, prewarning and warning and management for the received signals and transmit control commands to the monitoring subsystems to carry out control; and the monitoring subsystems can be cooperated with the central room to carry out monitoring or independently carries out monitoring to realize automatic control. The invention can realize real-time and dynamic intelligent control, prewarning and warning, security management and automatic monitoring for a large boiler or a boiler group and a heating network system and has the advantages of energy saving, consumption reduction, comprehensive analysis, safety, stability and economic operation.
