The development of bed occupancy sensor system

Abstract

Bed Occupancy Sensor System (EBOS) is a joint industrial project developed by a Start-up Company eVida and the author. The system aims to provide fall prevention and bedsore prevention functions for patients in hospital and nursing homes. It detects patients’ moving patterns and issue alarms to the caretaker to attend the patients. The system is composed of a waterproof mattress with sensors, a control unit with network communication capacities and a computer software to collect and analysis data. The objective of this FYP is to equip the control unit with network communication function and develop a computer program to serve as a centralised control panel and data storage point. We have developed a program that enables the control unit to send data via Wi-Fi communication and a computer program to receive and store data. The testing results show that the softwares can perform the functions with high reliability.
