ABSTRACT Precise information on the origin of timber can be obtained by using an identifier system, which can help in preventing illegal logging, managing timber supply chains and increasing value adding. Radio frequency identification (RFID) is increasingly used in log-tracking systems. The RFID tags currently available on the market are not directly suitable for forestry applications, however, unless the tags are protected by a housing. Harsh working environments mean that tag housings must be robust in order to keep their valuable information safe throughout a logging operation. The aim of this study was to provide a testing method for use as a decision-making tool by RFID users. The study used five tests to evaluate the applicability of eight kinds of tag housing for forestry applications. The tests considered climatic aspects, mechanical stress, readability and survival in the field. The method was found to work well with tested tag housings, revealing their strengths and weaknesses. Using the testing method, a procedure is recommended to determine the most appropriate tag housing.

热带林业工作环境中射频识别标签外壳的比较

摘要 使用标识符系统可以获得关于木材原产地的精确信息，这有助于防止非法采伐、管理木材供应链和增加附加值。射频识别 (RFID) 越来越多地用于日志跟踪系统。然而，目前市场上可用的 RFID 标签并不直接适用于林业应用，除非标签受到外壳的保护。恶劣的工作环境意味着标签外壳必须坚固耐用，以便在整个测井操作过程中保持其宝贵信息的安全。本研究的目的是提供一种测试方法，供 RFID 用户用作决策工具。该研究使用五项测试来评估八种标签外壳在林业应用中的适用性。测试考虑了气候方面，机械应力、可读性和野外生存。发现该方法适用于经过测试的标签外壳，揭示了它们的优点和缺点。使用测试方法，建议使用一个程序来确定最合适的标签外壳。
