Abstract：To cope with the effective connection of the transmit information with different protocols in remote monitoring system for alert?鄄situation information，a multi?鄄protocol conversion of Modbus based on remote monitoring system and its implementation method was given in this paper. The system consisted of protocol conversion module，server or cloud platform，and remote clients. The protocol conversion module is used for Modbus protocol parsing and encapsulation，and connecting with the alert?鄄situation information aquisition unit adopting Modbus protocol. The server or cloud platform is used to receive and store alert?鄄situation information，push the information timely to remote clients such as smart phone etc.，and receive and transmit control command from remote clients to local actuator via the protocol conversion module. The remote client is used to receive real time alert?鄄situation information and send control instruction. The main contribution of this system is that the real time alert?鄄situation information can be pushed to remote clients and the remote instruction can be dealt in time，thus the remote monitoring of alert?鄄situation information can be achieved effectively.
