Asset Tracking with ZigBee

Objective

Keeping track of high-value assets can be a time-consuming and expensive business. Wiring a large building with a detection system will do the job, but the cost may be prohibitive. Covering an outdoor area using a system connected by cables may not be possible. ZigBee offers a simple, scaleable solution at a fraction of the cost.




Approach

Cambridge Consultants developed a location system based on ZigBee technology in which battery-powered ‘nodes’ are placed around a site to create a security network. A node is then placed on each asset, allowing it to be tracked discretely and efficiently.

Result

The system provides a map showing the zoned location of each asset. The assets are tracked around the building in real-time and an alarm is raised if one is moved too close to an exit or if it is no longer being detected. The nodes also send back telemetry data such as temperature.

Benefit

The wiring costs when setting up the system are reduced to zero and all assets can be reliably traced. The potential to enhance the system, for example with two-way communications, is also available.
