Lonworks技术是美国Echelon公司于90年12月推出的一种现场总线技。LON（Local Operation Network）为局部操作网络，具有现场总线技术的一切特点。Lonworks分布式测控网络技术，它真正并彻底地贯彻了“分散控制、集中管理的控制思想，在国际和国内都得到越来越广泛的应用。更准确地说Lonworks技术有效地解决了集散控制系统的通讯难题。Lonworks技术符合IEEE- 1437和EIA-709标准。 这是一个Lontalk协议栈的C语言参考实现，包括一个参考文档。极具参考价值-Lonworks technology is the Echelon Corporation in the United States 90 years in December launched a fieldbus technology. LON (Local Operation Network) for local operation of networks, fieldbus technology has all the characteristics. Lonworks distributed monitoring and control network technology, it is truly and thoroughly implement the

现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.
