Study on Measurement System of Cement Cooler Clinker's Temperature Field
A system of measuring temperature field is introduced in this. It is CCD colorimetric method, which achieves non-intrusive measurement of temperature field. This article describes the principle and the structure of measuring system in detail, analyses selection principles of system parameters. Experiments are carried out, and measurement results show that this method can measure clinker temperature distribution, the system can meet the measurement requirement of cement cooler for clinker temperature field. Such doing provides credible assurance for automatic control of cement cooler
A two-color spatial-scanning pyrometer for the determination of temperature profiles in combustion synthesis reactions
This article describes a new two‐color pyrometer able to obtain multiple temperature reading using charge couple device type sensors. The device was tailored to fit the characteristics of self‐propagating high‐temperature synthesis processes in order to be able to detect temperature profiles and propagation rates of the combustion front. The light intensities at the two working wavelengths and the relative temperature profile are detected in 512 or 1024 points on the sample surface. The time between the acquisition of two profiles can be varied between 100 ms and 10 s. The pyrometer is interfaced with the BUS of a PC and is fully software programmable. The constructive details, procedure for sensors alignment, and temperature calibration are described. Few examples of applications are discussed.
Research on Control and Planning of Soft-Wing UAV for Haze Removal
The existence of fog and haze has caused great pollution to the environment. The research of removing haze is a hot topic in recent years. In this paper, a special haze removal algorithm based on Soft- Wing UAVis proposed. In this algorithm, two track control strategies are designed based on the Soft-Wing UAV model transfer function. A SIMULINK platform based mathematical model of Soft-Wing UAV is built to testified effectiveness of the two track control strategies. An autonomous ergodic-planning algorithm with greedy strategy and foldback algorithm for Soft-Wing UAV is designed. Within the algorithm, the haze regional has been modelled, the cost matrix is constructed, and the planning and ergodic strategy is proposed. Finally, the experimental results validates the reliability of the algorithm in the application of haze removal with the proposed evaluation Index.
