摘要
由于用户信息量庞大且多样,使得传统智能控制端嵌入式操作系统无法对其进行有效控制,能耗不稳且控制效率低。因此,构建能耗稳定且控制效率高的智能控制端嵌入式操作系统,该系统由传感器网络和终端组成。传感器网络由采集模块、微处理模块和智能通信模块组成。采集模块利用PT100传感器采集传感器网络节点信号,并经由AD7793模/数转换器将初始信号转换成电流信号和电压信号。微处理模块集中管理采集模块传输来的信号,并将管理后的信号传输到智能通信模块中进行多步处理,以获取电压和电流的最终信号。终端管理整个系统的工作流程,并通过处理电压和电流的最终信号,提供给用户多种控制指令。软件给出了终端控制信号采集工作的流程图,以及系统调用电压和电流最终信号的代码语言。实验结果表明,所设计系统拥有能耗稳定、控制效率高的特点。
Since the traditional intelligent control terminal embedded operating system can＇t control the huge and diverse in- formation effectively, and its energy consumption is unstable and its control efficiency is low, an intelligent control terminal em- bedded operating system with stable energy consumption and high control efficiency was built. The system consists of sensor net- work and terminal. The sensor network is composed of acquisition module, microprocessor module and intelligent communication module. The acquisition module collects sensor network node signal by means of PT100 sensor, and converts the original signal into current signal and voltage signal by means of AD7793 AD converter. The microprocessor module performs a centralization management of the signals from the acquisition module, and transmits the signal to the intelligent communication module for multi-step processing to get the final voltage and current signals. The terminal controls working process of the whole system, provides users with a variety of control instructions by processing the final voltage and current signals. The flow chart of the terminal control signal acquisition and code language that the system calls voltage and current signals are given. The experimental results show that the designed system has the characteristics of stable energy consumption and high control efficiency.
