At present, the domestic demand for long-term care is growing rapidly. However, the replenishment of related services has been slow. This leads to an imbalance in the proportion of nursing staff. The result was a shortage of manpower and a hectic work schedule. If there is a system to assist caregivers in their daily work processes, the burden on caregivers reduces. The constructed system in this research has the functions of Bluetooth indoor positioning, abnormal state judgment, early warning with processing flow control, active reminder, and recording of nursing work. Indoor positioning is used to instantly locate the elderly, know their activity statuses, and determine whether the activity is abnormal. In the event of possible abnormal conditions, active and passive alerts are issued. Through the combination of software and hardware, the processing flow is controlled to achieve the optimal allocation of manpower. In addition, proactively reminding the attendant and recording the care items before carrying out the care needs are conducted to avoid omission or duplication of care items.
