Abstract: Failsafe control system can improve the safety of personal and environment. We used failsafe PLC and PROFIBUS-DP field bus to structure the car rear bumper welding line, introduce the hardware configuration and programming.

Abstract: How to test the communication robustness of high-bandwidth and low-latency network under harsh environments is critical for evaluating reliability of network. The accuracy of data transmitted by large-scale network control software under busy communication is fully verified in the paper, by means of the simulation to simulate uncertainty time and link failure phenomenon of data transmission occurs in the real application environment to complete the test of robustness for the large-scale network control software, which is useful for assessing the reliability of the network.

Abstract: Nowadays, lots of efforts have been made to develop new technology for navigation system of underwater vehicle with the increasingly improved requirements of precise positioning, obstacles-avoidance, energy-saving in locomotion and stabilization in response to turbulent currents. In nature, fish have a great ability to localize prey, school, navigate, rheotaxis, etc. using the lateral-line organ. The biological lateral line system has inspired the researchers’ efforts to artificial lateral lines for applications in underwater vehicles and robots. In this paper, the working mechanism of the fish lateral line system has been described. Then the research status both at biology and at mechanics on the artificial lateral line system at home and abroad has been reviewed. To make a comparison with acoustic navigation system USBL,The key technologies and developing tendency as well as potential applications are described. At last, an insight on the future research directions and route of artificial lateral-line system have been given.

Abstract: The computer virtual control method for thermostatic process of sand casting and gas forming tester system is studied in this paper. The system software is designed based on LabVIEW, which includes the design of temperature controller interface, the construction of virtual system and the design of system interface. This paper is of certain directive significance to future exploitation of virtual control system.

Abstract: Based on the establishment of a system of electronic control gasoline engine, we try to develop and optimize a set of electronic control fuel injection system which aims at the LJ462Q gasoline engine. At the same time, we can provide the beneficial reference for the other similar product’s design and development.

Abstract: The problem of robust fault detection filter is investigated for a class of systems with unknown disturbance and fault inputs. Attention is focused on formulating the design the residuals match with reference model. The robustness of the residual system is proved to be stability. The existence condition of the above filters, which can guarantee the robustness against disturbances and sensitivity against fault are solved by LMI. Finally, an example is given to illustrate the feasibility of the proposed method.

Abstract: With the popularization and development of Internet, the network has penetrated into every corner of social life. Network brings people convenient but at the same time it also brings a series of safety problems. Intrusion detection system is an important part of network security system. Computer security problem is increasingly prominent, which puts forward higher requirements on intrusion detection system. In this paper, the application of data mining and intelligent Agent detection in the intrusion detection system is researched.

Abstract: The coal safety has always been the focus of attention. So it is important to monitor the location of the mine personnel and display it on the the monitoring computer for the timely and effective rescue when the mine disaster occurs. The mine personnel positioning system is made up of Zigbee and LabVIEW software. The system has a better performance in system security, data storage, positioning accuracy, report printing, etc. It has a higher degree of automation and more apparent display. The research focus on the communication of LabVIEW software and the lower computer, the data processing, real-time reports and historical data.

Abstract: In this paper, NIR diffuse reflectance spectroscopy as well as the PLS method was adopted for rapid determination of vitamin C in navel oranges. The GN method was employed to select calibration and validation samples. The spectral data in the region 900-1600nm were used for modeling. The coefficient of determination of the validation set is 0.8690, and RMSECV is 1.039mg/100g. The results suggest that NIR diffuse reflectance spectroscopy may serve as a strong tool for developing an on-line fruit sorting system.
