‘B-Fixed’ stands for ‘Beacon Fixed’. Bluetooth beacons are deployed at fixed locations to be used as beacons for indoor tracking. This intelligent asset management solution is based on the lastest LoRa, Bluetooth and GPS technology. The solution uses the latest IoT technology to strengthen the management of onsite personnel, acquire real-time location information of personnel, and precisely document the time when personnel enter and leave the construction site. Electronic fences are set to specific regions of the site to control the in and out of personnel. It also performs an analysis of the duration of vehicles staying on construction sites. Therefore, the management level is significantly enhanced. Safety risks are reduced, and construction efficiency is improved. This solution is also applicable to asset tracking management. It tracks and calculates assets in real-time. It also supports geo-fences so that alarm will be triggered when the device moves or the tag falls off. Features of this tracking system are: Wide network coverage Easy to install devices, no need to set premises distribution system Long standby time Indoor and outdoor seamless tracking This document aims to introduce the composition, features, software development methods, and project implementation methods of the system.
