Aiming at issues such as the limitation of operating spot and supervision inconvenience of traditional lo-cal monitoring methods used by cascade control system, this paper proposes a solution of remote monitoring system of cascade control system based on mobile network. A hardware platform based on wireless data terminal realized the remote wireless monitoring of cascade control system through the cooperation with the server and client software developed in the Windows system. The wireless data terminal was developed based on MC9S12X128MAA MCU of Freescale company which was combined with wireless transmitting module EM770W M2M of HUAWEI company. The remote monitoring system was designed to transmit through 3G networks and Internet, the information of the wireless data network terminals jobsite equipment parameters to the server which can store and forward them. Users could achieve real-time on-site monitoring and control of the equipments by monitoring the operations of the clients. In addition to the remote monitoring functions, the system also included a remote upgrading capabilities. The over-all scheme of the system was presented. And the implementation of software and hardware of lower computers, the software of host computer were introduced in detail. Practical experiment shows that the system could work stably with a friendly HMI, and meet the desired effects.
