By ‘twice pre-bending method’ in the first forming step, the springback law can be obtained. With the springback law and the target angle, the exact punch displacement which determines the formed angle in each bending step is predicted. In the succedent forming steps, the bending process is carried out with the exact punch displacement by real-time revising the springback law. And the angle error in each forming step is calculated by comparing the actual formed angle with the target angle. By conducting compensation for the last angle error in the next forming step, each precise bending process step is realized. A system of intelligent control technology for forming the steel pipe was developed. A calibration method is proposed to calculate the exterior parameters of the CCD camera, in which the equilateral triangle is em-ployed as the calibrating board and only one image needs to be captured. A mathematical model, which converts the angle in the image into the actual formed angle, is derived. The experimental results showed that the ellipticity of the formed pipes was less than 1.5% and the high-quality pipes can be manufactured without the worker's operating experience by employing the in-telligent control technology.展开更多

文摘The economy of distribution networks largely depends on the utilization rate of distribution network equipment.Most of the emerging intelligent power consumption technologies have a positive effect on equipment utilization and their use can save investment of distribution networks.In this paper,the influence of intelligent power consumption technologies on the utilization rate of distribution network equipment is reviewed.The evaluation methods and indexes are assessed first and then intelligent power consumption equipment with energy storage function,vehicle-to-grid(V2G)technology and time-of-use(TOU)tariff are reviewed respectively.It is concluded that these intelligent power consumption technologies and measures have great potential to improve utilization rate of distribution network equipment because of their effective improvement to power load.Meanwhile,recommendations on how to utilize these intelligent power consumption technologies to improve utilization rate of distribution network equipment are proposed.

文摘With the rapid development of intelligent technology,the smart heightened-containment biological laboratory(sHCBL)has moved from concept to reality.Experimental activities and laboratory construction,operation,and management will undoubtedly lead to disruptive changes.Conventional laboratories are increasingly being replaced by smart laboratories;however,the key technologies involved in this transition remain at an exploratory stage.It is necessary for HCBLs to absorb the advanced ideas of smart laboratories to guarantee the establishment of biosafety and biosecurity in a more automated way.This study examines in detail sHCBL module structures,the functions of each module,laboratory operation processes,and the advanced nature of smart laboratories.It may provide a theoretical foundation for the future transformation and smart construction of sHCBLs.
