Control system and method for IoT boilers using central management server

A control method of a plurality of IoT boilers in a control system of the plurality of IoT boilers, the control system comprising the plurality of IoT boilers, each IoT boiler checks an operation state to transmit state information including its identification information, and senses whether or not a fault occurs through a sensor to transmit fault information including the identification information, a plurality of manager terminals, each manager terminal includes a boiler control application for monitoring and controlling the IoT boilers, monitors states of the IoT boilers, receives control information for controlling the IoT boilers from a manager, and transmits the control information, and a central management server that is connected to the IoT boilers and the manager terminals through a network, the control method comprising:

• periodically or non-periodically receiving and storing the state information of the IoT boilers from the IoT boilers, by the central management server;
• receiving the fault information including the identification information from at least one IoT boiler among the plurality of the IoT boilers, by the central management server;
• identifying at least one manager terminal, which corresponds to the identification information included in the fault information, among the plurality of manager terminals, based on data stored in a database of the central management server, by the central management server;
• transmitting, to the at least one identified manager terminal, a fault code corresponding to the fault information, and receiving, from the at least one identified manager terminal, the control information for addressing the fault occurred in the at least one IoT boiler, by the central management server;
• and
• transmitting received control information to the at least one IoT boiler, by the central management server, for addressing the fault.
