Intelligent Elderly Care System Upgraded：VDB03 Bluetooth

2025-07-18/ By Admin

In today's era of increasingly pronounced population aging, how to provide more comprehensive and timely protection for the elderly in nursing homes and care centers is a core challenge for managers. Risks such as lost personnel and sudden discomfort that make it difficult to call for help in time constantly worry both family members and managers. Micro Energy Information Technology has launched the VDB03 iBeacon Bluetooth positioning wristband (with trigger button version), which combines an advanced Bluetooth positioning system to provide a set of efficient and reliable real-time personnel positioning management and emergency assistance solutions for nursing institutions. This significantly improves safety management levels and emergency response efficiency.

The traditional management of nursing homes usually relies on the inspections by caregivers and the use of call bells, but this approach has significant drawbacks:

• Location unknown: It is impossible to keep track of the exact location of each elderly person in real time. Especially in public activity areas, gardens, and other open spaces, it is difficult to detect if an elderly person strays or enters restricted areas in a timely manner.
• Delay in calling for help: When an elderly person suddenly experiences discomfort (such as fainting or angina pectoris), they may be unable to reach the call button or express themselves clearly, thus missing the golden time for rescue.
• Lax management: There is a lack of digital tools for analyzing personnel activity trajectories and warning of regional gatherings, etc., resulting in insufficiently refined management.
• Family members' anxiety: Family members cannot easily obtain real-time information about the whereabouts and status of their loved ones, which can lead to worry.

VDB03 Bluetooth Smart Watch Smart Solution

Real-time precise positioning

Each elderly person wears a lightweight and comfortable VDB03 bracelet (with a trigger button version). The bracelet is based on Bluetooth 4.2 technology and operates continuously in the iBeacon broadcasting mode, with a broadcast range of up to 70 meters.

Bluetooth gateways from MicroEnergy Information Technology are deployed in key areas within the institution (corridors, activity rooms, dining halls, garden entrances and exits, etc.). They function like sensitive "ears", continuously receiving the unique signals (including UUID, Major, Minor Mac addresses, etc.) broadcast by the bracelets.

The Bluetooth gateway collects the signal strength (RSSI) and other data it has gathered and uploads them to the cloud server. The powerful Bluetooth positioning engine in the cloud analyzes these data in real time, and precisely displays the real-time location of each elderly person wearing the bracelet on the electronic map of the management platform. Nursing staff and administrators can have a clear understanding of the locations of all the elderly people in the hospital through computers or mobile apps.

Press the "SOS" key to activate the emergency alarm

The prominent trigger button on the side of the VDB03 bracelet is the crucial "lifeline". When the elderly person feels unwell, needs urgent assistance, or encounters other dangerous situations, they only need to press it gently.After the button is triggered, the bracelet will immediately broadcast the preset SOS alarm information via Bluetooth signals.The nearby Bluetooth gateway quickly captures this special alarm broadcast and immediately uploads it to the management platform.The rescue workers were able to reach the exact location of the incident immediately, thus gaining precious time for saving lives.

Intelligent Area Management

The management platform can set up electronic fences. For instance, the stairwells, equipment rooms, unopened areas or the boundaries of nursing homes can be designated as "restricted areas" or "danger zones". Once a senior wearing the VDB03 bracelet enters or approaches these areas, the system will automatically issue an out-of-bound warning, alerting the caregivers to intervene promptly to prevent accidents (such as falls, getting lost and leaving the facility). The system can also trigger alarm for prolonged stays (such as when a senior stays in the bathroom for too long) and conduct aggregation analysis to assist managers in optimizing the allocation of service resources.

Long-lasting and durable, with convenient management

VDB03 is powered by a button battery and features an ultra-low power consumption design, ensuring an extremely long battery life (typically several months). The battery can be easily replaced, making maintenance simple and the cost low. Through the accompanying mobile app, administrators can remotely modify the bracelet parameters, such as the broadcast frequency, transmission power (within the compliance range), and device name, to adapt to different environmental needs. There is no need to individually retrieve the bracelets. The product complies with strict certification standards such as ROHS/FCC/CE, and is safe and reliable.

Characteristics

Deploying the VDB03 Bluetooth positioning wristband system brings significant value to nursing homes:

Security enhancement: Real-time positioning + one-key SOS, significantly reducing the risk of getting lost and improving the speed of emergency assistance, making the elderly feel more secure and the family more at ease.

Efficiency improvement: Caregivers can reduce the time spent on blind search and focus on providing higher-quality care services; managers can achieve precise management through data dashboards.

Risk avoidance: Intelligent warnings such as electronic fences effectively prevent potential accidents and reduce operational risks of the institution.

Brand image: By adopting intelligent management methods, it enhances the professional and modern image of the institution, strengthens market competitiveness.

The VDB03 Bluetooth positioning wristband with a trigger button from Weichen Information is not merely a positioning device; it is also an intelligent "guardian" that safeguards the safety of elderly residents in nursing homes. It seamlessly integrates advanced Bluetooth positioning technology, emergency call function, and cloud management platform, creating an invisible safety protection network for nursing institutions. This enables precise real-time personnel positioning management, instant emergency assistance, and intelligent daily management. Choosing VDB03 is choosing to empower care with technology, building a solid and reliable safety barrier for the later years of the elderly population, eliminating any risks in safety management and ensuring constant care.
