关键词： STM32   蓝牙   RSSI   RFID   防丢器   门禁  

摘要： 在现实生活中,人们经常有需要“找证件”“找耳机”“找钱包”“找钥匙”等困惑。为此,设计基于蓝牙定位技术的智能防丢器。智能防丢器设计采用STM32作为主控芯片,结合蓝牙模块、灯光闪烁指示和响铃指示,使用蓝牙接收信号强度指示(RSSI)定位算法实现在室内或近距离对防丢器的定位追寻的功能。通过无线射频识别技术(RFID)用防丢器替代门禁卡的功能,实现门禁卡与防丢器“二合一”。该设计极大地减少了人们在日常生活寻找物品时所花费的时间和精力,避免因丢失物品而带来的损失和不必要的麻烦;同时配合门禁功能,还提升了人们生活的舒适度与方便度。

关键词： 散货装卸   门机抓斗   RFID   防碰撞  

摘要： 传统的散杂货码头,装卸船舶主要依靠门座式起重机(以下简称门机)进行装卸作业。通常情况下,为提高作业效率,当船舱内货物快要见底的时候,需要安排挖掘机或者装载机进行清仓作业。在作业过程中,由于门机体积大,驾驶员视线盲区多,容易发生门机抓斗与船舱内作业机械碰撞的事故,轻则是机械的损坏,重的造成舱内机械驾驶员的人身伤害,因此,如何有效避免门机抓斗与舱内机械的碰撞一直是港口管理者非常关注的安全问题。在装卸船舶过程中,各港口虽然也采取了一些技防手段来防止碰撞事故,例如,在门机大臂上安装高清摄像机,让门机驾驶员看的更清楚;在船舶的舱口安装隔离绳,区分作业区域,防止抓斗与舱内机械碰撞等。这些措施在一定程度上减少了事故的发生,但是受到人为因素和环境因素的影响,作用不是不明显,并且费时费力,占用人工成本较高。本文探讨一种基于RFID技术的门机抓斗防碰撞预警系统,实用性强,部署简单实用,主要利用RFID技术,在门机抓斗上安装RFID射频标签,同时,在舱内机械上安装射频读写器,当门机抓斗靠近舱内机械时,提醒司机进行避让,达到防碰撞的效果。

摘要： RFID technology, as an important intelligent perception technology, provides a more efficient, convenient, and intelligent way for library management and services. However, the security issues of RFID (Radio Frequency Identification) systems have gradually emerged, such as tampering with RFID tags and system cracking. In order to address the security issues of RFID technology in smart libraries, a RFID security algorithm based on intelligent perception systems was studied. This algorithm utilized the location information, physical properties, and communication features of RFID tags to achieve location privacy protection, and improved the security of the algorithm by combining dynamic and static keys. The simulation results showed that the algorithm had a high recognition rate (Max: 94%) and security (Max: 97.9%), which can effectively achieve RFID system identification of tag identity, effectively prevent tag attacks and cracking, and improve system reliability.

摘要： This paper presents a lubrication management support system, built on a concept previously developed by the authors, which is currently being implemented in one of the industrial plants. This system enables the use of established Industry 4.0 solutions and allows us to reach the benefits of implementing intelligent solutions related to data analytics even before the transition from manual lubrication methods to automated methods. The system described uses tools such as RFID, AR, and IoT, allowing relatively simple, cost-effective, and direct involvement of maintenance personnel in both data collection and the use of modern technologies to support lubrication management tasks.

摘要： The growing popularity of IoT (Internet of Things) devices and the ever-increasing multiplicity of their applications ranging from security issues of automated locking systems in homes or hotels to contactless payments. This poses more and more challenges for RFID (Radio-Frequency Identification) users to raise the level of security. Problems of RFID-based devices often involve limited access to computing resources or persistent memory, which is associated with the low cost of the devices and their wide range of applications. The subject of this research is the comparative analysis of the power of communication signals between reader and transponder and reader and attacker. Measurement results were quantified, and the signal was compared for two types of modulations: ASK (Amplitude-Shift Keying) and PSK (Phase-Shift Keying), presenting their readings in the form of contrast histograms based on Fourier transforms. Based on the readings obtained, a security method was proposed based on an algorithm that allows 100% detection of attempted attacks on RFID devices based on the signal power emitted by the transponder to the reader. The conditions under which the effectiveness of the method is possible were also determined based on experiments for IoT devices.

摘要： RFID technology application has made multi label collisions and security privacy issues increasingly prominent in logistics warehousing. A solution that combines RFID and chaotic encryption algorithm has been proposed and applied to anti-collision and security protocols for logistics warehousing labels to address these issues. Firstly, optimization analysis was conducted on the anti-collision of warehouse system labels using chaotic sequences. By comparing different types of labels, it was determined that the 6TypeB label has good anti-collision ability. On this basis, a bidirectional security authentication protocol based on a chaotic encryption algorithm for 6TypeB labels was studied. The data privacy and security of tags can be effectively protected by this protocol. Finally, a detailed analysis was conducted on the performance of 6TypeB logistics warehousing labels used. The 6TypeB system has an average label recognition rate of 73%, an average transmission efficiency of 95.31%, and an average memory usage rate of 93%. Meanwhile, the average stability of the bidirectional security authentication protocol based on the 6TypeB label system is 92.08%. By utilizing 6TypeB, data privacy and security of RFID can be significantly improved, leading to a new application direction for anti-collision and security of logistics warehousing labels. © 2023 Yunhai Gu, Fei Xia, Weihua Wang, Song Yang and Yuqiong Ye, published by Sciendo.
