A data recording system for fault diagnosis of hybrid electric vehicles was studied by taking the integrated starter and generator (ISG) hybrid electric vehicle as the investigation object. The fault diagnosis communication net was established using a CAN bus and a K line. As designed, the system hardware structure included a CPU processing module, a communication module, and a USB recording module. With the system requirements and characteristics in mind, special circuit design and analysis of USB mass storage module were carried out based on the hardware scheme and software design. In the running test, the fault data recording system worked stably, and the data was recorded integrally and correctly. At the same time, the online display data accurately reflected the vehicle's running status.  相似文献

In CDMA communication system, the relativities between users result in Multiple Access Interference (MAI). With the increase of users, MAI becomes the main jam of broadband CDMA communication system. Multi-User Detection (MUD) is the most important technology of anti-jamming in the broadband CDMA communication system, which can eliminates MAI effectively by using the information of all user signals to detection single. This paper analyze the expression of system capability without MUD and with MUD, and puts forward the way to increase system capability by using MUD. Then the influence of MUD on CDMA system capability is discussed by MATLAB emulation. Basing analysis and emulation, the conclusion is got: the higher the MUD efficiency, the better the improvement of CDMA system capability; under the same MUD efficiency, the lower data rate, the smaller inter-cell interference, the lower the ratio of bit energy to power spectrum, the better the improvement of CDMA system capability.  相似文献

This paper analyzes the relationship between the performance of incumbent firms and the net entry of new firms by combining various theoretical views of entrepreneurship. Different regression models to treat dynamics and endogeneity issues are applied to test the research hypothesis with regional micro‐data for 61 Vietnamese provinces from 2000 to 2008. The main finding is that net entry is associated with the performance of incumbent firms and the overall performance of the economy. Incumbents' growth and gross domestic product growth induce changes in the existing production system and stimulate the creation of an economic environment more favourable to new firm formation. Consistent with the hypotheses put forward within the “knowledge spillover,” the “error‐correction,” and other approaches, incumbents may generate new entrepreneurial opportunities not only for themselves but also for the whole society.  相似文献

The communication of the application program among work tations of 3+ network is realized by the shared file on harddisk of the network server,which does not support the application program' s real-time communication among the network workstations nor supplies software or hardware needed for information refreshing, nor fits for field multibatch continuous real-time transmission and processing of working condition information, by using the NETBIOS function call method, the real-time communication among network workstations is realized and a power plant working information background real-time communication and data processing system is developed which effectively traces working condition from tow 200 MW power plant generators, altogether 321 points from a cycling detecting system and 78 binary points for broadcasting the information to other workstations,and realizes a complx display of 14 working condition graphs and a real-time data simulation graph.  相似文献

The mobile IPv6 protocol solves the mobile communication problems in the next generation Internet.The mobile IPv6 not only provides huge address space,but also strengthens handover ability of mobile user,and realizes route optimization.IPv6 will become the next generation Internet protocol;so the mobile IPv6 will be widely used in the next generation Internet.The moblile IPv6 will provide in the future network,a uniform transmission platform that transmits data,voice data and video data,or other services.People not only put forward more and more requirements for multimedia playing operation,but also bring forward higher request,which is interaction capabiliby communication,Because the long latency associated with mobile IPv6's return routability procedure of correspondent node binding,this paper presents a fast correspondent node binding of method based on early binding updates option.The method not only eliminates at least 50% of the additional delay that a standard correspondent node binding adds to the network stack's latency,but also reinforces the ability to support alternant real-time application.  相似文献

The paper mainly analyzes and studies mode of bus communication based on optical fiber at one_point to multiple_point and mode of point_to_point communication based on wireless at one_point to multiple_point. The advantages and disadvantages of two communication modes are given. Considering the demands on FA data communication,the paper presents transmitting data based on network mode and connection mode,implementing application protocol based on object oriented mode and international standard. Considering the requirements of FTU unit for data communication, the paper proposes the network inner operating system in FTU unit, which is indispensable. Data are transmitted on client/server mode, defined and organized on object oriented mode and transmitted on logical address.  相似文献

This article puts forward a 3 Layers Model for the communication between embedded system and PC. It is based on the speciality of them and the TCP/IP model. The model defines the communicate process of embedded system to be three layers: Transport Layer, Control Layer and Application Layer. Each layer serves for its higher-up. It can keep the efficiency and credibility of the communicate process and the authors prove and analyse that in the article. the concept of the model is also suitable for Bluetooth, IrDA and other kinds of communication about embedded system.  相似文献

It is not able to provide the decision service information that should be instantaneous, exact and all-around for governor by means of traditional mode of information communication. And it is important problem faced by modernization office. In order to get the needed information instantaneously and satisfy requirement of coordination work, the paper presents a kind of enterprise office information platform based on dynamic coordination work. The platform can guarantee coordination work of the system dynamically and instantaneously, and it is stronger in functions, and facility in use. It is discussed in more details to the design of dynamic coordination workflow drive and coordination message service drive and so on. The application effect of practical engineering shows that the design is successful.  相似文献

According to the reality of the development of fire alarm system in our country, this paper offers a fire alarm information system based on Internet. Being different with the way of normal router in transmitting all data packages fairly, a new dispatch algorithm is put forward, which can identify different data packages of demanding different real-time performance and transmit the data packages of demanding high real-time performance by jumping queue intelligently. That decreases warning time delay and improves the dependability of important data transmitted by router. A new kind of method is proposed to satisfy a high real-time system at a low cost.  相似文献
