Design of the detecting platform for the electronic control rotary dobby

In order to meet the factory detection requirements of the rotary electronic dobby, a new design of the detecting platformfor the rotary electronic dobby was proposed in the present study. It was composed with three main modules to meetthe different levels of detecting process all over the factory, including the embedded control system, human machineinterface system and the information management system. For the information management system of the dobbyworkshop, the proposed platform performed the remote management, results monitor, and data analysis to the dobbymanufactured at the factory. For the operators of the dobby detecting process, the human machine interface systemrealized the edit of pattern, the upload and download of the pattern data based through Wi-Fi, the control of motor speed,the test process record and the upload of the test results. Moreover, the embedded control system was developed andbuilt to realize the real-time control to electromagnet and swing arms of dobby according to the pattern stored in flashchip and status display of the detecting results on the platform. The designed detecting platform in this article can bewidely applied in the factory for detection of the rotary electronic dobby. The reliability and practicability of the proposedplatform have been confirmed by the practical application of the dobby manufacturing enterprise.

Time Control

The progress of embedded control systems in the last several years has made possible the realization of highly-effective controllers in many domains. It is essential for such systems to provide effective performance at an affordable cost. Furthermore, real-time embedded control systems must have low energy consumption, as well as be reliable and timely. This research investigates primarily the feasibility of implementing an embedded real-time control system, based on a low-cost, commercially off-the-shelf (COTS) microcontroller platform. It explores real-time issues, such as the reliability and timely response, of such a system implementation. This work presents the development and performance evaluation of a novel real-time control architecture, based upon a BeagleBoard microcontroller, and applied into the PWM (pulse width modulation) control of a three-phase induction motor in a suction pump. The approach followed makes minimal use of general-purpose hardware (BeagleBone Black microcontroller board) and open-source software components (including Linux Operating System with PREEMPT_RT real-time support) for building a reliable real-time control system. The applicability of the proposed control system architecture is validated and evaluated in a real case study in manufacturing. The results provide sufficient evidence of the efficiency and reliability of the proposed approach into the development of a real-time control system based upon COTS components.

Localization Method

The workflow management system plays an important role in enterprise information management system. An enterprise workflow contains a lot of business process and their relevancies. These relevancies are important in building workflow management system. This paper proposes a business relevance based workflow localization method to divide the workflow locally. In this method, a workflow is treated as a combination of local processes; therefore single task can be divided into several subtasks. This method can reduce the difficulty and improve the efficiency in building workflow management system. This method has been practically applied to the design and development of steel pipe production supervision control system. The actual results validate the effectiveness of the proposed workflow localization method.
