Adequate conditions are critical to avoiding damage or degradation of products during transportation, especially in the case of delicate goods like food products, live animals, precision machinery or art items, among others. The damages are not always readily identified: sometimes they are only detected several days or weeks after the merchandise has been delivered. Moreover, it may be hard to assess if the problems resulted from the transport conditions, and it may be even harder to prove it, making it difficult to determine and assign responsibilities. Also, transport is a global business, typically involving different companies and means (truck, train, plane, ship, …). Usually, customers hire the service to a single commercial entity, but the service is performed by several companies, like transporters, stockists and dispatchers. To know whether the transport requirements are fulfilled or not is thus essential to assessing responsibilities and encouraging compliance by all the players in the process. In this paper, the authors propose an architecture that allows certifying, in an exempt manner, the conditions under which the transport of sensitive goods are carried out. In case of compliance, it protects the entities of the transport chain and ensures the customer that the merchandise has not been subject to conditions that may have affected its integrity or quality. If problems are detected, it allows to identify the non-compliant players and to assign responsibilities. The solution is based on ultra-low-power, low-cost devices (equipped with several sensors, a real-time clock, and Bluetooth Low Energy services), a mobile application and several cloud services (including a Coordinated Universal Time service).
适当的条件对于避免产品在运输过程中受损或退化至关重要,特别是对于食品、活体动物、精密机械或艺术品等易碎品。这些损坏并不总是容易识别的:有时在货物交付后几天或几周才会发现问题。此外,很难确定问题是否是由于运输条件造成的,甚至更难证明这一点,这使得确定和分配责任变得困难。此外,运输是一项全球性业务,通常涉及不同的公司和运输方式(卡车、火车、飞机、轮船等)。通常,客户会向单个商业实体租用服务,但该服务是由几家公司提供的,如运输商、仓储商和调度员。因此,了解运输要求是否得到满足对于评估责任和鼓励所有参与方遵守规定至关重要。在本文中,作者提出了一种架构,允许以豁免的方式证明敏感货物运输条件得到满足。如果符合要求,它将保护运输链中的各个实体,并确保客户商品没有受到可能影响其完整性或质量的条件的影响。如果发现问题,它可以识别不合规的参与者并分配责任。该解决方案基于超低功耗、低成本设备(配备多个传感器、实时时钟和蓝牙低能服务)、移动应用程序和几个云服务(包括协调世界时服务)。
