摘　　要：针对传统串级调速系统采用的就地监控方式存在的使用地点的局限性,监管不便等问题,笔者提出了一种基于移动网络的串级调速系统的远程监控系统的解决方案。以Freescale公司的处理器MC9S12X128MAA为控制单元,结合华为EM770W M2M无线传输模块开发的无线数据终端为硬件平台,配合在Windows系统下开发的服务器、客户端软件,实现对串级调速系统的远程无线监控。所设计的远程监控系统利用无线数据终端通过3G网络和Internet网络将作业现场的设备参数信息及时传输至服务器端,在服务器端进行存储并转发。用户通过在监控客户端的操作,以实现对现场设备的实时监视和控制。除远程监控功能外,系统还具备远程升级功能。阐述了系统的总体设计方案,并详述了下位机软、硬件的实现和上位机软件的实现。实际试验表明系统运行稳定,人机界面友好,达到预期的效果。Aiming at issues such as the limitation of operating spot and supervision inconvenience of traditional local 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 overall 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.
