Fall detection and avoidance

The current solution is a PIR sensor placed in the room of residents-at-risk. It is powered by means of an adaptor and conveys limited information to staff, requiring advance knowledge by the team of which rooms have the units.

The aim of the project is to scope a better solution to the PIR sensor-based nurse calling system with better improvements by performing below tasks:

• Analysis of existing nurse calling system
• We aim to describe the internet module interface on to the existing system (Includes old and new systems)
• Automatic WiFi setup for the Havenwood building
• Architecture to get detection alerts to mobile phones or email (count the number of detection)
• External power supply
• Alternative sensor which can be replaced in the place of existing sensor unit
• Sensor detection is performed and communicated over internet, later the data is decoded with the radio receivers.

The team in TSSG compared existing products available in the market based on a pre-agreed set of criteria and created a technology comparison table. The team then conducted a sensor analysis to create solutions to the existing PIR unit focusing on detection quality, along with a list of requirements and contingencies for future applications. However, converting internet signals to radio signals is not feasible to the above use case and is expensive technology therefore conversion of internet signals to radio signals was not achieved.
