基于GPRS的无线温度控制系统将分为现场和远端两级进行控制,现场为温度信号采集及温度控制执行;远端部分为承担算法的上位机,通过GPRS网络远端接收到温度数据后,在线计算得到控制数据,再通过无线网络将数据传输到现场对系统进行精确的控制。在设计中,采用了MATLAB等仿真软件实施仿真,不仅有效地加快了设计的进程,而且完善了设计方案仿真。实践运行结果表明,这种控制方法不仅实现了无线远端控制,而且资源开销少,响应速度快,控制过程稳定,能满足实际要求。
GPRS-based wireless temperature control system will be divided into two levels of field and remote control, the scene for the temperature signal acquisition and temperature control implementation; the remote part of the algorithm for the host computer, through the GPRS network to receive remote temperature data, Online calculation of control data, and then through the wireless network to transmit data to the scene for precise control of the system. In the design, using MATLAB and other simulation software to implement the simulation, not only effectively speed up the design process, but also to improve the design simulation. The results of practical operation show that this control method not only realizes wireless remote control, but also has less resource overhead, fast response and stable control process, which can meet the actual requirements.
