智能科学与技术的知识体系:语义分析的结论 总被引:2,自引:2,他引:0
本文从分析"智能"、"Intelligence"、"科学"、"技术"的语义入手,首先界定了"人类智能"、"人工智能"、"智能科学与技术"概念的内涵,进而构建了"智能科学与技术"的知识体系,继之导出了"智能科学与技术"专业教育的课程体系。本文的讨论取得了若干颇有新意的研究结论:真正与英文的Intelligence对应的是中文的"智";"智能"是"智的能力"的简称;"智能"应该是"能智";智能科学与技术的知识体系由两个理论和四种技术构成,据此决定了智能科学与技术专业教育应该设置的六门主干课程。 相似文献

基于IAP15F2K61S2设计了一种低成本门禁控制系统,以IAP15F2K61S2为核心控制器,分别利用了传感器FM70和MFRC522门禁卡模块以及4x4的矩阵键盘来接收外界信息,利用AT24C02芯片来存储信息,使用液晶显示器12864来进行显示。当输入正确密码或者指纹信息以及1C卡感应时就会启动开门程序,多次输入错误的密码时会报警。实验表明,设计的门禁系统可以较快准确地识别密码等信息,从而进行相应的开门动作或报警。系统成本低,适用于民间普及。 相似文献

考虑到无人机群在协同完成任务时对时延的高要求,选用先验式路由协议OLSR(Optimized Link State Routing)协议。但无人机自组网中无人机节点高速移动和能量有限的特性,使得OLSR选举出来的MPR(Multi-Point Relay)节点可能会因此而丧失MPR资格,从而导致时延增加,网络开销增大。针对该问题,提出一种基于节点速度和能量的MPR集选择算法,运用HELLO分组在邻居探测的过程中感知节点能量和速度,之后在MPR选举前根据节点速度和能量对一跳邻居进行预处理,从而使速度快能量低的节点永不成为MPR节点。排除掉节点后,在节点意愿值相同的情况下再次对节点的速度和能量进行加权计算,选出最优MPR节点。仿真结果表明,基于节点速度和能量的MPR集选择算法在时延、吞吐量、节点能量消耗三个指标都具有良好的特性。 相似文献

煤矿事故严重威胁人们的生命和财产安全,瓦斯作为煤矿事故的罪魁祸首,其主要成分是甲烷。因此,选择一种性能优良并且能够实时探测甲烷浓度的气体传感器对安全生产和检测大气环境是十分有意义的。在众多气体传感器中,光纤气体传感器由于容量大、损耗小、体积小、抗腐蚀、抗干扰能力强等优势受到学者和仪器制造商的青睐。本文对比了几种光纤气体传感器,基于光谱吸收技术的光纤气体传感器体积小、成本低、功耗小,其使用最为广泛。在光谱吸收技术的基础上,发展了一种高灵敏度的探测技术,腔衰荡CRD(Cavity Ring-Down)技术。相比于普通的光谱吸收技术,其吸收光程长,灵敏度高出3个~4个数量级,并且对光源强度稳定性要求不高。但是,为了有效、实时地探测到衰荡信号,该技术对探测器的速度要求极高。本文研究的频移干涉腔衰荡FSI-CRD(Frequency-Shifted Interferometry Cavity Ring-Down)技术,通过将腔衰荡技术结合频移干涉技术,构建了频移干涉腔衰荡甲烷传感系统,实现了衰荡信号从时间域到频域的转换,降低了对探测设备的要求,并通过实验验证了该系统可以用于甲烷气体浓度的测量。 相似文献

The study on nonlinear control system has received great interest from the international research field of automatic engineering.
There are currently some alternative and complementary methods used to predict the behavior of nonlinear systems and design
nonlinear control systems. Among them, characteristic modeling (CM) and fuzzy dynamic modeling are two effective methods.
However, there are also some deficiencies in dealing with complex nonlinear system. In order to overcome the deficiencies,
a novel intelligent modeling method is proposed by combining fuzzy dynamic modeling and characteristic modeling methods. Meanwhile,
the proposed method also introduces the low-level learning power of neural network into the fuzzy logic system to implement
parameters identification. This novel method is called neuro-fuzzy dynamic characteristic modeling (NFDCM). The neuro-fuzzy
dynamic characteristic model based overall fuzzy control law is also discussed. Meanwhile the local adaptive controller is
designed through the golden section adaptive control law and feedforward control law. In addition, the stability condition
for the proposed closed-loop control system is briefly analyzed. The proposed approach has been shown to be effective via
an example.
