In plate rolling, the existence of some asymmetry rolling conditions, affects the distribution of transversal thickness of rolling pieces, leading to the occurrence of camber phenomenon, which in turn seriously affect the product's material yield. In this paper, based on the images of plates in the production line collected by camera, taking into account the requirements for on-line measurement, filtering noise from image information, use edge detection operator, Hough transform methods and sub pixel edge location method to identify the steel plates, have achieved in-line measurement of camber curvature of plate side. At the same time, combined with camber control model, we have developed camber curvature measurement and control system, realized the automatic correction control of camber curvature of rolling pieces in the production process. Field applications show that this method can reduce the human intervention, will limit the camber curvature of rolling pieces within a certain range, which has great significance for improving the product’s yield.

This article presents the development of an on-line measurement and control system for process characterization and optimization of the nanoparticle manufacturing process, called the submerged arc-spray nanoparticle synthesis system (SANSS). To achieve optimized control of particle uniformity, this research investigates the feasibility of employing optical fiber probe and the dynamic light scattering (DLS) technique to monitor and control particle sizes. According to the theory of DLS, an on-line nanoparticle sampling and measurement system was developed and integrated with the SANSS as an important step to verify the measurement performance of the proposed method. To examine the measurement accuracy of the developed system, calibrated polystyrene latex particles with known accurate sizes were employed to verify the particle sizing accuracy of the proposed system. The data conformity between the measurement results of TiO2 nanoparticles obtained by various methods, including TEM, a calibrated commercial particle sizing system and the on-line measurement system, has indicated that the developed method was feasible and effective.

Water and fertilizer are two important factors in seedlings growth and development, the reasonable management of water and fertilizer can play a greater growth potential for seedling, and blind management of water and Fertilizer not only is harmful for seedling growth, but also will lead to the water resource waste and environmental pollution. In order to precisely determine the seedlings fertilizer demand, this paper presents a method seedlings fertilizer and water measurement and control system based on wireless sensor network, the system can realize automatic deployment of information acquisition node, data self-organization transfer, namely, wireless communication, and can accurately detect information of soil water and fertilizer and identify water and Fertilizer on the best demand of seedlings growth stages for different seedlings, different regions, different period of climate and seedling growth status, so the best water and fertilizer control is achieved in seedling cultivation. This system were introduced and analyzed from the hardware structure, software structure and so on in this paper, and it has the advantages of low power consumption, low cost, good robustness, flexibility and so on. The experiment results shown that the system is practical and efficient, which can be applied in farmland, and nursery area.

To resolve the limited transmission and complicated layout, the common parameter measurement and control system of agricultural equipment use virtual instrument technology and embedded technology. The research results show that the wireless transmission data of the system is accurate and reliable. The linearity errors of acquisition divestiture (AD) and frequency counting (FI) channel measurements are only 0.38% and 0.006%, respectively, and the resolution is 0.01V and 1 Hz. This performance evaluation fully meets equipment detection in agricultural use. The system is integrated with various wireless transmission platforms, intelligent agricultural equipment, and computer wireless reception and processing. These parameters can significantly improve the automation level and quality of agricultural equipment.
