T Food Safety plays a crucial role in today's society, and is a growing concern and serious matter for consumers, companies involved in the food chain, as well as for government authorities. In this paper, the authors introduced traceability and analyzed challenges of whole chain traceability. Based on some real practices, the authors argued that a whole chain traceability system is important as the...
In allusion to the characteristics of infrared CCD imaging, a novel infrared video real-time processing system based on TMS320DM642 DSP chip is proposed in this paper. We analysed the mechanism of real-time processing infrared video, proved the real-time processing performance of DM642 by experiments and designed the system. The system hardware mainly includes video capture module, video processor...
The low-voltage power line as a transmission medium, proposed to power line carrier technology, through the power line carrier signals to monitor the operational status of electrical equipment to protect electrical equipment. The large-scale medical equipment is of the great significance. Through the intelligent management system can be well managed to use these large-scale medical equipment, saving...
This paper presents a scheme to perform the message sharing of the Integrated Protection for power system. The concept of integrated protection is introduced, in which data and message allover the substation even the whole power system can be obtained. Software of the integrated protection is designed to achieve the message sharing goal. As the basic unit in the software program, every thread stands...
With the development of turbine-generator unit at the direction of high parameters, high capacity, and in order to ensure that the unit is safe, reliable and operated optimally, research of monitoring and fault prognostics system for turbine-generator units have now become an important research topic. Using the advantages of embedded system such as fast computing speed, small size, low power consumption,...
During underwater scanning, navigation, and other tasks, the acquisition of large scale 3D terrain information is very important for underwater vehicle (UV) navigation and safety. In this paper, we propose a new approach to underwater target detection using a discontinuous digital laser scanning grid. It is shown that the proposed approach can suppress scattering background noise generated by suspended...
Combining with the characteristic of Web technology and field working requirement, Embedded Web Server (EWS) integrates the information acquisition and diffusion into the field embedded measurement and control equipments by the standard interface and communication protocol. And the EWS in the equipments can provide the browser-based operation and control interface through Internet. Ethernet for Plant...
As the Profibus is generally applied in the field of control, its feature of real-time has become more and more important. This paper promotes an improved analyzing method on the single-master Profibus stations. In this method, single-master Profibus DP networks' feature and its protocol are analyzed, and the impact on the messages' real-time and network load of different priority level using different...
The real-time fault diagnosis system is very great important for steam turbine generator set due to a serious fault results in a reduced amount of electricity supply in power plant. A novel real-time fault diagnosis system is proposed by using strata hierarchical fuzzy CMAC neural network. A framework of the fault diagnosis system is described. Hierarchical fault diagnostic structure is discussed...
One time radial vibration, mostly caused by rotary eccentric load, may reduce the reliability and operating life of motors. In order to mitigate the one time radial vibration in permanent magnet motors, a real time detection method for rotary eccentric load based on the theoretical analysis of the motor vibration and the mechanical analysis was given, and a novel control strategy based on FOC (field...
With the rapid development of the field of industrial process control and the fast popularization of embedded ARM processor, it has been a trend that ARM processor can substitute the single-chip to realize data acquisition and control. A new kind of remote I/O data acquisition system based on embedded ARM platform has been researched and developed in this paper, whose hardware platform use 32-bit...
The turbo-generator unit is very important equipments for electric power production, which has a high rate of fault and causes a lot of harm because of the structural complexity and the special circumstance. With the increasing of the capacity of the unit, the condition monitoring and fault diagnosis plays an important role to ensure safe operation and guarantee the efficiency. Therefore, the real-time...
