First, the application background:
With the continuous advancement of the national economy and technology, various industries are gradually moving towards intelligent development, and the healthcare sector is no exception. In recent years, many hospitals have invested significant financial and human resources to modernize their facilities, which has greatly improved medical equipment and hospital environments. However, there are still several challenges that need to be addressed:
1. When a patient is alone in the ward or accompanied by a guardian, sudden illnesses can occur without immediate access to medical assistance, leading to potentially serious consequences.
2. Patients may leave their rooms or even the hospital without permission, posing safety risks.
3. There is a lack of centralized management and monitoring for medical equipment, making it difficult to track and maintain them effectively.
4. Important areas such as storage rooms and medicine cabinets lack strict security measures, increasing the risk of theft or misuse.
5. The management of newborns remains a critical issue, with concerns about identity confusion and safety.
Second, the system objectives:
The Chengdu Anxun LINK UWB high-precision positioning system utilizes a wired network to provide seamless coverage throughout the hospital. It calculates time differences to achieve a positioning accuracy of up to 10 cm, supporting the simultaneous tracking of multiple tags. The system is fast, flexible, and automatically registers any new tag upon entry. With intelligent management software, it enables label management, map display, and real-time tracking of movement paths, achieving efficient and accurate information management.
Third, the application cases:
Patient medical record management: Previously, retrieving a patient's medical history was time-consuming. With the Chengdu LINK UWB system, each patient wears an active tag that stores their medical information. Staff can view real-time data and monitor patients through the management center. The system uses a wired network for seamless coverage, transmitting signals every two seconds. By calculating signal time differences from three base stations, it accurately tracks the patient’s location and displays their movement on a map. If a patient moves out of a designated area, the system immediately triggers an alarm, enabling staff to respond quickly and prevent incidents.
Medical equipment management: Key devices are equipped with active tags that store device details. These tags transmit signals at one-second intervals, allowing staff to view device information and historical locations in the monitoring room. This enhances the security and efficiency of equipment management.
Patient safety management: When a patient is alone, they can press the button on the tag to send an automatic alert. The system then notifies staff, who can respond promptly, significantly improving patient safety.
Baby identification: Ensuring the safety of newborns is a major concern for both parents and hospitals. The LINK UWB system provides harmless, durable tags that emit pulse signals. These tags store baby identity information and allow parents to check for errors through the monitoring room. The tag also includes a thermometer for real-time temperature monitoring. If the temperature is abnormal, the system alerts staff immediately. Additionally, if a baby leaves the designated area, the system sounds an alarm, preventing potential kidnappings.
Medical waste monitoring: Tags placed on medical waste transmit pulse signals at regular intervals. The system monitors the entire lifecycle of waste, from disposal to final handling. If a tag deviates from its set path, an alarm is triggered, reducing the risk of environmental contamination. This helps build a solid foundation for information technology in waste and radiation safety management, ensuring the safe disposal of hazardous materials.
Fourth, the system summary:
Chengdu Anxun Electronics Co., Ltd. is a high-tech enterprise integrating R&D and production. It specializes in developing advanced technologies, including UWB wireless precision positioning systems, radio communications, and electronic countermeasures. The LINK UWB system employs cutting-edge UWB technology, offering cellular sub-area positioning, high-speed data transmission with ultra-narrow pulses, low power consumption, strong security, resistance to multipath effects, and robust electromagnetic interference performance. It supports fast networking, rapid positioning, and high accuracy, making it ideal for real-time tracking of people and objects in various environments. The system is scalable, capable of expanding coverage and the number of tracked individuals as needed. It is suitable for both indoor and outdoor applications, meeting requirements for security, scheduling, and navigation.
