传统方式下的高校图书馆对于图书文献的入库和出库管理大多是基于条码识别技术来完成的,尤其是书籍入库时更是需要对书籍信息进行录入确认和编目分类确认工作,这种方法存在工作效率低的缺点.提出了一种基于物联网的图书电子标签系统,利用RFID技术和自定义通信协议实现了对图书信息的管理,系统采用恩智浦CLRC663射频芯片实现图书信息的存储,上位机采用C#编写,数据库存储图书信息、电子标签信息、学生卡信息和图书借阅信息等,实现了图书标签的智能化;该设计方案性价比高,可行性较好,相对于传统的解决方案提出了一种全新的设计理念和实现方法.
This paper describes the architecture, principles, advantages and disadvantages of user services strategy evaluation. And a new evaluation system is proposed, which can be used in local library. Using BP neural network structure, this system can better solve qualitative evaluation problems. The result show that this system can achieve service strategy evaluation accurately and rapidly.
At present the inspection conclusions of exported seafood with traditional qualitative inspection can not reflect the influence of products’ quality difference on the risk.This paper introduces BP-neural network into the risk analysis process of seafood,and uses DLL method which calls Matlab using VC to make a quantitative assessment on the risk of exported seafood.The advantages and disadvantages of VC and Matlab are compared,and the modeling method of neutral network and the procedure of the mixed programming of them are described in detail.The test results show that the method has higher accuracy and feasibility,and provides a new solution for the exporting risk assessment of seafood.
This paper presents the development trend of virtual reality in digital library.At first, it shows the relationship between the DL and VR in detail,a combination of both on the formation of the inevitability of the development of VR. Secondly, Digital Library based on VR is described. And at last, problems, limitations and trends on DL are given.
This paper puts forward an E-government information network security assessment system model based on Agent, makes detailed analysis on the architecture,merits and key technologies of the model, and proves the performances of the model in E-government information security risk assessment through the system test.
To overcome the hidden danger of manual broadcasting in buses,a novel intelligent passenger information system has been proposed.The system is composed of SPCE061A single chip computer,GPS,LCD and keyboard.Through comparing GPS signal and the bus-stop information stored in NAND Flash in real time to determine information of the coming stop,then the information is released.The system offers more safety,intelligent,accurate and stable passenger information than those provided by manual broadcasting.
This paper presents a Random number generation system of examination based on VC++.It shows the architecture and structure,merits and key technology in detail.The system can further improve efficiency and flexibility and it is especially fit for Institutions of higher learning.At last,a full realized software is shown.
The mixed programming for VC++ and Matlab can unit their advantages to increase the efficiency in simulation and development.In this paper,three seamless mixed programming skills such as Matcom Add-in,Matlab Visual Studio Add-in and COM is discussed in detail,these skills is simple,efficient code and seamless integration with the VC++ and have been widely used in the interactive field.Therefore,implementation steps in the course of programming are presented;Finally,the advantages and disadvantages of various methods and their application are proposed.
SPI Bus interface with simple equipment, transmission reliability,and efficient features are widely used,but some of SCM or embedded system does not have SPI interface,which limits the application of SPI equipment to some extent.This paper proposes a method to realize serial communication by timing simulation,and verified the feasibility of this approach through communication between SPCE061A system and the SD card module.
课程考试是检验教学效果的一种有效方式,它能为高校进行教学改革提供必要信息.但是目前高校考试管理中存在着许多亟待解决的问题,影响了考试工作的正常进行.因此,采取有效措施,加强考试管理,使考试管理更加科学化和规范化,充分发挥考试的积极功能,是高校考试管理工作的一项重要内容.本文在分析这些问题的基础上,提出了相应的对策.
Simulated annealing is a general optimization method which stochastically simulates the slow cooling of a physical system . The algorithm works by iteratively proposing changes and either accepting or rejecting each change. The proposed change may be accepted or rejected by the Metropolis criterion .The algorithm in IC design was also discussed. At last some experimental results of simulated annealing were given. A high performance IC design way can be achieved on the basis of algorithm.
