摘要： 传统的图书借还流程需要在人为辅助下进行且图书馆每天开放时间较短,在生活节奏快以及职业、生活多元化发展的今天,难以满足现代人的需求。为了提高图书借还效率,有效管理图书馆图书借还产生的数据,减少人力物力资源的损耗,本文研究设计了一个运用WIFI技术、RFID技术和WEB技术的自助图书借还终端系统。系统主要由自助借还书终端机、WEB服务器和数据库服务器三部分组成。读者可利用带有RFID标签书籍和RFID借书卡,在图书自助借还终端自助地完成借书和还书。终端机同时将读者借书还书信息发送至WEB服务器,信息经WEB服务器处理后,上传至数据库服务器中。系统可代替人工借还书服务,在提高图书借还效率的同时保证图书馆服务质量,可实现图书馆无人管理以及长时间开放。

摘要： Bio-integrated wireless sensors in the form of conformable plaster, based on the Radiofrequency Identification (RFID) communication, have been recently proposed for the battery-less measurement of the human skin temperature. However, the response of the Integrated Circuit (IC) transponder is sensitive to the strength of the interrogating power. Indeed, high power produces artifacts on the sampled temperature up to 2 degrees C when the mutual position between reader and sensors, as well as the emitted power, can not be carefully controlled. Hence, a reliable adoption of this technology in real cases is challenging and still in question. A combined macro-scale electromagnetic-thermal model is here introduced to predict and correct the above artifact so that the temperature measurement becomes insensitive to the RF power collected by the IC. The method is based on the new generation RFID ICs with on-chip temperature sensor that are also capable to give back the strength of the collected RF power. The model is validated in controlled conditions and then applied for different skin temperature measurements on human body. An average accuracy of +/- 0.25 degrees C, compared with a reference calibrated thermocouple, was demonstrated in the considered tests.

摘要： The application of the elements of the Fourth Industrial Revolution (4IR) through the development of a Flexible Manufacturing System (FMS) for manufacturing operations in the railcar industry will promote flexibility, intelligent coordination of the manufacturing operations, efficient handling and quality control. Some production systems in the railcar industry are non-responsive to changes in real time thereby leading to reduction in productivity, hence, the need for a FMS that will cater for the dynamics of manufacturing operation. This work proposes a FMS, which encompasses the assembly line, lean production, logistics and quality assurance. The system comprises of the Radio Frequency Identification Technology (RFID) for components identification and process control, arrays of sensors and cameras, automated material storage and supply, standard interfaces such as the interface for the internet of things (IoT), the robotic welding system as well as a robust intelligent control system. A framework for the implementation of the FMS was developed while the simulation of the designed system was performed using the Anylogic 8.2.3. software. Based on the results obtained, there was an inverse relationship between the operating cycle time of the conveyor and the conveyor speed per cycle when the conveyor’s performance was simulated at a speed of 3 m/s and 7 m/s. The results showed that the system can suitably perform the sequence of assembly and quality assurance operations during the manufacturing of railcar subassemblies with minimal interruptions and human intervention. This will promote production of component parts with high structural and dimensional integrity with significant reduction in the manufacturing cycle time and cost.
