Abstract: To verify the validity of fault control measures, a verification platform with software fault injection and hardware fault injection is developed to conduct fault diagnosis measures for MCU control system. For the faults occurring in the internal units of a controller, program debugger is employed to simulate software or hardware faults by varying the data; for the faults occurring in peripheral circuits, a circuit of fault-settings is employed to simulate hardware faults, i.e., open-/short-circuit and electrical level variation. This verification platform is applied to evaluate software measures to control the faults/errors in accordance with IEC60335/IEC60730/UL1998/CSA22.2.08, and a case of induction cooker is presented shows how it works. Experimental results show that the verification platform runs stably and accurately, and has a big value in practice.

Abstract: In order to solve the existing project management information chain, decentralized management, low efficiency problems. This paper put forward ideological based on the main line information technology means and multi-dimensional integration principle. And the paper comprehensively consider a kind of integrated management mode for various factors related with the project from the decision-making stage to put to use in all phases.

Abstract: Using virtual instrument technology, digital signal processing technology and traditional optical radiation measuring technology to construct optical radiation measuring system breaks the construction methods of traditional instruments. Signal processing, collection, control and process of measuring system are implemented by the software LabVIEW8.2. And they are integrated in a computer. The computer not only is data processing center, but also is instrument control center. While measuring, the user uses the mouse to operate the handles including knobs, switch and buttons of virtual instrument panel to select instrument functions and set various parameters, which realizes measuring optical radiation with different wave bands and different intensity. And the user can change instrument operation panel, modify system software, transform instrument function, and customize instrument parameters, which embodies the idea that the software is the instrument.

Abstract: Now computer terminals, communication control, and network technology continues rapidly developed, the rapidly expanding range of information exchange, has been covering the field device to the control and management at all levels of networking, industrial control monitoring is not only limited to on-site monitoring, on-site scheduling. The development of industrial monitoring control system is a history of development of centralized monitoring and control to the network monitoring control. The previous system, the various important instruments status were monitored by the large-scale instruments.

Abstract: With the rapid development of network communication technology, the computer can not only control the local equipment, but also control remote devices through the network. With the development of the network and its applications in-depth development, in the past few years, many new network applications are familiar to people based on its application. Network control system is the one, where the network is used as a tool to connect the bridge side and device-side operations. C/S mode

Abstract: This paper proposes a block Mean-Shift algorithm based on target real-time update and LBP texture features, through the target update improves the accuracy of target tracking, enhances the local character of the target through the target block, so as to improve the robustness of algorithm based on skin color backgrounds. And then analyze the Mean-Shift algorithm cannot recover quickly lost target tracking defects, and its improvement by combining the frame difference method.

Abstract: The express delivery industry of China is relatively backward in the automation degree of critical business processes. The basic reason is that the business-related supporting data, which is scattered in the multidimensional space, is difficult to utilize and process. This paper proposes an automatic data acquisition framework to resolve such difficulty, which synthetically utilize intelligent inernet of things (IoT), semantic web and complext event processing (CEP) technology. We also implement a SCEP prototype system with the capability of real-time detecting complex business events on the goods sorting line, which adopts a detection method consisting of four stages. The simulation results show that the system has good performance and feasible enough to deal with the complex business which need data support from multidimensional space.

Abstract: This article introduces two ways of calculating the transmission parameter of the mechanical system in the aircraft based on the traditional computational method. One is the method of fixed point coordinate which is based on spatial Analytic Geometry and spatial coordinate transformation can calculate the motion parameter of various links, the effective radius of the limit position rocker as well as the transmission ratio by fixed point coordinate. The other method can establish the model of control system by using the MDT module of the three-dimensional mapping software CATLA. It also can realize analog computation and system optimization which points at the transmission parameter of the mechanical system by using DMU module.

Abstract: This paper describes the chemical equipment and design overpressure conditions. Analysis of the different setting conditions on the discharge area of influence drawn: set a smaller discharge pressure tends to reduce the discharge area; reaction should be increased to increase the quality of the material discharge area; For gas system, increasing large volume of the reactor or the design pressure discharge area required can be reduced, when designing the reactor discharge area is too large can not meet the case of volume of the reactor can be increased and thus meet the requirements of the design pressure. By analyzing the results, in the design of the discharge system, can effectively reduce the discharge area, to meet safety and economy.
