Construction is one of the most dangerous industrial sectors. Struck-by object or equipment is one of the main causes of fatal accidents on construction sites. Although many regulations have been designed for preventing struck-by accidents, they still happen and lead to many injuries and fatalities. The application of real-time location systems (RTLS) on construction sites provides new possibilities in construction safety management. Previous researchers have proposed using RTLS to track the locations of workers and equipment on construction sites to improve construction safety. However, they have the limitation of cabling problems. Also, providing effective safety alerts to workers within dangerous proximity to equipment has not been well addressed. This paper aims to develop a method for detecting the proximities as well as providing proximity safety alerts to workers on construction sites using Bluetooth Low Energy (BLE) RTLS. Here, vibro-tactile alerts representing different cases of proximities were defined. Unnecessary alerts were filtered out to avoid desensitizing workers. A number of tests were conducted on a construction site to test the prototype system developed based on the proposed method. The results indicate that the system is capable of detecting proximities and generating timely vibro-tactile alerts, which can be easily perceived by the workers.

建筑业是最危险的工业部门之一。被物体或设备撞击是建筑工地致命事故的主要原因之一。尽管已经制定了许多法规来防止碰撞事故，但它们仍然会发生并导致许多人员伤亡。实时定位系统（RTLS）在施工现场的应用为施工安全管理提供了新的可能性。之前的研究人员提出使用 RTLS 来跟踪施工现场工人和设备的位置，以提高施工安全。但是，它们具有布线问题的局限性。此外，在危险的设备附近向工人提供有效的安全警报也没有得到很好的解决。本文旨在开发一种使用蓝牙低功耗 (BLE) RTLS 检测接近度以及向建筑工地的工人提供接近度安全警报的方法。在这里，定义了代表不同接近情况的振动触觉警报。过滤掉了不必要的警报，以避免使工作人员麻木。在施工现场进行了大量测试，以测试基于所提出方法开发的原型系统。结果表明，该系统能够检测接近并及时产生振动触觉警报，工人很容易察觉到这些警报。过滤掉了不必要的警报，以避免使工作人员麻木。在施工现场进行了大量测试，以测试基于所提出方法开发的原型系统。结果表明，该系统能够检测接近并及时产生振动触觉警报，工人很容易察觉到这些警报。过滤掉了不必要的警报，以避免使工作人员麻木。在施工现场进行了大量测试，以测试基于所提出方法开发的原型系统。结果表明，该系统能够检测接近并及时产生振动触觉警报，工人很容易察觉到这些警报。
