The invention discloses a centralized scheduling resource distributing load balancing device and method. According to the centralized scheduling resource distributing load balancing device and method, the calculation and analysis pressure of intelligent terminals is shared, the intelligent terminals and a centralized scheduling service system are separated and decoupled, and the framework flexibility is achieved; a resource distribution server enables every centralized scheduling server to obtain the related intelligent terminal, and enables centralized scheduling services to issue and synchronize information to the intelligent terminals and receive and store data uploaded by the intelligent terminals; disadvantages of data bi-synchronization, complex service scheduling and the like are overcame, the system complexity is simplified, and the system maintainability is improved; a centralized scheduling service system is extracted to perform tasks of unified task allocation, equipment accounts, stipulation distribution, data summarization, alarm uploading, project issuing and the like, load balancing is performed on the system through distributed deployment, adaptive adjustment of the system is achieved according to the number and tasks of the servers of server tasks, the system stability is well guaranteed, and the system operation stability is not influenced by downtime of the scheduling services.
