Abstract: Traditional methods, such as artificial operation and synchronization software, can not guarantee the reliability of data transmission and synchronization of water information. A solution of data bidirectional communication based on Message-Oriented Middleware (MOM) is proposed. According to various demands, MOM is deployed at platforms of different levels of water information centers, and data efficient management and real-time sharing of water information system are realized by ActiveMQ clusters and load balancing technology. The proposed scheme is applied to the data center platform of torrential flood monitoring system, which verifies the effectiveness, flexibility and reliability of data communication.
