摘要：针对传统的生产监控存在浪费和效率低下等问题，在IEEE 802.15.4无线通信协议的基础上，根据系统低功耗的需求，设计并实现了与生产监控软件相配套的具有两级结构的新型无线智能传感器网络，它能完全反馈终端设备所有信息；在软件设计中采用了一个简单的多任务操作系统，并在无线通信协议中定义了两个无线通信信道：一个用于数据；另一个用于控制、仲裁和时间同步。实验结果证明，该方法简单易行，既能保证设备的生产效率，又能获得满意的数据传输准确率和数据传输速率。

Abstract: Aiming at existing the problems of waste and inefficiencies in traditional productive monitor, a new wireless communication protocol based on the IEEE 802.15.4 was introduced. According to the request of lowpower consumption,a twolevel structure of novel wireless smart sensor network was designed and realized to cooperate with the productive monitor software by feeding totally snapped devices states information. A tailored multitask operating system was designed in the software. Two wireless communication channel was defined in the wireless protocol, one for the data, and the other for control, arbitration, and time synchronization. Experimental results indicate that the improved method which is implemented easily can guarantee the processing efficiency of device, and it can get satisfied accuracy and data transmission speed.
