摘要:
A method for compensating nonlinear characteristic of thermocouple vacuum gauge is proposed. Least squares support vector machine (LS-SVM) is adopt as compensation model, of which parameters are optimized using particle swarm optimization (PSO) algorithm. Experimental results using data obtained on-site show that the proposed approach effectively compensates the nonlinearity characteristic, and the accuracy of this method is higher than those obtained by SVM model.

摘要:
In tobacco industry, the air for feeding tobacco and the air for dusting are supported simultaneously to save energy and reduce emission. Feeding speed is vital to the quality of the production. The paper puts forward a control system based on Advanced RISC Machines(ARM), touch panel and PLC. It describes the component structure of control system, control principle and the design of hardware and software in detail. Testing results showed that the built system is running well in the cigarette maker and demonstrated excellent performance like fast and accurate response and strong robustness. Air speed during feeding is controlled precisely with deviation less than +/- 1 m/s. The system satisfied all standards of design requirement. Effective tobacco feeding will increase production safety and decrease energy and tobacco consumption.
摘要:
A simulation system for instrument cluster based on the CANoe from Vector company is developed and used for real-time cluster test and fault analysis. Test results show that the operation condition of cluster can be simulated and the fault data from CAN bus can be collected, replayed and analyzed using this system.

摘要:
Nuclear pulse is directly related to the radiation intensity but influenced by statistical fluctuation. Because most available rate-meters have complex structure of circuits, we introduce a chip-microcomputer-based nuclear count rate measuring system which is easily incorporated into isotope gauges for measurement on level, density, thickness, etc. To make continuous measurement of the count rate, the time period is divided equally into a lot of intervals. The sample frequency is increased by making the interval smaller. The box car averaging and self-adapting weighted algorithm for continuous count rate measurement are explained in details. Simulations show that both methods can substantially decrease the statistical fluctuation by appropriately choosing the number of data used for on-line measurement and the weighted algorithm gives minimum variance. In a word, the measuring system is a fast rate meter with simple construction and high accuracy.

摘要:
This paper introduces an instrument for measuring the size and shape of almost any pipes' interior profile. It describes the components and principle of operation of the instrument. A modular DSP system embedded in the instrument to process the image makes the measurement fast and accurate. The design of the instrument is given from five areas such as optical, electrical, electronics, etc. It has been tested that the information derived from the intelligent instrument can assist not only in making repair decision but also in the generation of the 3-D structure of the pipes.
