摘要： Composite filament materials with embedded sensors are increasing in demand to create 3D printed hierarchical sensor structures in a cost-effective and scalable way for the development of wearable and geometry-conforming sensing devices. Traditional methods of encapsulating sensors with polymers are implemented through techniques such as adhesive bonding and potting. For microelectronic device encapsulation, the plastic moulding technologies are employed. However, final products from these methods have geometry constraints and are not easily customizable. This paper presents a methodology of fabrication of polymer filaments embedded with 550-µm radio-frequency identification (RFID) chip using extrusion process for 3D Printing applications. The fabricated filament (3 mm diameter) is manufactured with a 1.5 mm extrusion nozzle specifically designed for this process and controlled by an RFID reader. The RFID sensor filaments produced by this extrusion encapsulation technique were successfully used to produce objects on an existing Fused Deposition Modelling (FDM) 3D printing machine. Such filaments and printed devices are wireless, battery-less, flexible, customizable, and repairable, and hence are advantageous in new sensor applications including the internet of things (IoT). The 3D printed objects produced via this process will have the ability to sense the environment and communicate with reader devices due to their unique embedded RFID codes. This development will subsequently open new avenues for meeting the growth in IoT demands forecast as a pillar of industry 4.0.

摘要： Complex manufacturing and supply chain systems consist of concurrent labour-intensive processes and procedures with repetitive time-consuming tasks and multiple quality checks. These features may pose challenges for the efficient operation and management, while manual tasks may significantly increase human errors or near misses, having impact on the propagation of effects and parallel interactions within these systems. In order to handle the aforementioned challenges, a digital twin (DT) integrated in a multi-agent cyber-physical manufacturing system (CPMS) with the help of RFID technology is proposed. The proposed reference architecture tends to improve the trackability and traceability of complex manufacturing processes. In this research work, the interactions occurring both within a single complex manufacturing system and between multiple sites within a supply chain are considered. For the implementation of the integrated DT-CPMS, a simulation model employing the agent-based modelling technique is developed. A case study from a cryogenic supply chain in the UK is also selected to show the application and validity of the proposed digital solution. The results prove that the DT-CPMS architecture can improve system’s performance in terms of human, equipment and space utilisations.

摘要： We can no longer imagine life without modern technologies. In many ways, they facilitate human labour, provide distraction or information. In the context of a modern dynamic age, technology is helping us speed up our work. In the transport sector, this is appreciated especially by customers to whom goods can be delivered faster. RFID technology is just such a technology. The main aim of the paper is to optimize working procedures at a specific railway station while using this technology in order to prove its efficiency in the field of speeding up transport. Streamlining processes is the key to reducing disruption and downtimes during transport. At the same time, in this way it is possible to increase the competitiveness of rail freight transport on the transport market and thus ensure better distribution of transport.

摘要： 为了对小区、宾馆及其它公共场所的出入进行有效的管理,设计一个功能强大的门禁管理系统是非常重要的。本设计采用无线射频识别(RFID)技术,以市面上应用广泛的单片机为控制系统的核心,同时采用传统的密码输入方式实现门禁系统的控制。本控制系统实现的功能主要有通过读取IC卡信息或输入密码开门、注册新卡、修改密码等。首先,系统读取IC卡成功或输入密码正确,LCD12864就会显示人员的信息,提示人员正常出入;其次,如果IC卡不能正常读取或密码输入错误次数超过预设值,LCD12864就会显示禁止出入,同时出发报警系统;最后,门禁管理系统的控制部分可以对IC卡进行注册、密码修改等。经过实践验证,本系统操作简单,能够对一些公共场所及住宅小区进行有效的出入管理,具有很大的实用价值。

摘要： The development of access control systems has progressed rapidly in recent years and the market offers a wide range of different devices. The design of the access control systems is specific to each object. It depends mainly on the operational requirements and the value of the protected interest. Access control systems have their own specifics that must be used during the designing a security system. Logistics centers are an ideal object for the implementation of access control systems. Inconsistent selection of access devices can cause inefficient system functionality, leading to downtime and losses. Based on experimental testing and related works in the field of access control systems, the paper discusses the possibilities of using access control systems in logistics centers and points out the specifics of RFID based access control systems.
