2. Working principle
The electronic tag or wireless device periodically sends a signal to the AP, or the AP actively searches for the electronic tag or wireless device periodically. After the AP obtains the signal, it is transmitted to the back-end positioning server. The positioning server uses the unique precise positioning algorithm created by UHF to display it on the web interface in real time. The specific location of the electronic tag or wireless device is displayed on the electronic map. At the same time, the tag can implement two-way communication with the server through the AP. The tag can send information to the positioning server, and the positioning server can also send instructions to the tag to classify and manage the tags.

2. The application of real-time positioning system (Wi-Fi RTLS) in the medical industry
1. Maternal and child management
Newborn babies have little difference in appearance. They have no sense of self-protection and need careful care from medical staff. The real-time positioning system can solve the problems of mother-infant pairing and infant anti-theft, and realize the safety of mother-infant. At present, RFID radio frequency technology is basically adopted for mother and child management solutions. Passive wristband tags are worn for babies and mothers. Medical staff hold RFID readers to read the information of mother and baby respectively and compare whether they are paired. Install RFID readers in the baby room. Only persons with passive tags can enter the baby room. Regularly read the visit records of the reader. Real-time monitoring is not possible, and it is impossible to avoid theft by people with passive tags. Or drop the baby.
Mother-infant pairing: Wear the Wi-Fi location electronic tag of the wristband on the ankle of the newborn baby. Before being discharged from the hospital, it is not allowed to open the tag unless there are special circumstances. Mothers also wear electronic tags. When the mother is admitted to the hospital and the baby is born, the hospital administrator enters the current and baby’s personal information in the tag. The medical staff holds the Wi-Fi PDA, reads the tag information in real time, and successfully compares the baby and mother’s information. , To avoid holding the wrong baby. If the mother and baby are paired incorrectly, an alert will be issued when the mother and baby’s tags are together. Remind nurses that a pairing error occurred.
Infant anti-theft: 1), disassembly alarm: the unique design inside the baby’s wristband tag, no matter how it is disassembled, it will trigger an alarm reminder of the tag to the positioning server; 2), the baby’s position movement alarm: if the baby is taken away In the baby room, the tag will also trigger the alarm prompt of the positioning server through the real-time location information transmitted. 3) Real-time monitoring with camera linkage: The real-time positioning system can be linked with camera monitoring. When the position of the baby with the tag moves, the tag will stimulate the camera to take pictures or video, upload the back-end positioning server, and the manager can view the baby’s status in real time. Security situation. Thus, the baby is effectively prevented from being stolen.
2. Special patient management
Special patient groups include: mental patients, disabled patients, patients with sudden illnesses, and children. These groups have poor self-management capabilities and require more complete and meticulous care from the hospital.
Real-time location information query: Wear an electronic tag to the patient, and you can view the real-time location information of the patient in the hospital on the back-end positioning server to ensure that the patient is in a safe environment.
Emergency alert: When a patient encounters an emergency, such as a disabled patient falling down in the bathroom, a child can’t find his ward, a sudden illness patient has a sudden onset, etc., the patient can press the label alert button he is wearing, the back end The positioning server immediately displays an alarm prompt, and the management personnel can immediately respond and arrange rescue.
Hospitals are particularly heavily managed: There are many areas where patients are prohibited from entering the hospital, which requires strict monitoring and management. If a patient with a tag breaks into this area, the alarm function of the back-end positioning server will be triggered to remind the management staff to deal with it immediately.
Security scope definition: In order to maintain the safety of special patients, the hospital can arrange special patients in a safe area according to actual conditions. If the patient walks out of the safe area, the tag carried by the patient will send an alarm message to the back-end positioning server, and the management can Arrange for medical staff to deal with it in real time.
3. Medical equipment management
The emergency medical equipment (for example: ventilator, oxygen device, etc.) of the hospital needs to be found in the first emergency, which puts forward extremely high requirements on the management of medical equipment. Place an electronic tag on the medical device, enter the medical device to be searched on the back-end low-end server, and immediately display the real-time storage location of the device on the interface, which is convenient for finding the device immediately and avoiding the first aid caused by searching for the medical device Time progress.
4. Supervision of special drugs
For some special drugs that require high temperature and humidity, and the monitoring of drug expiration dates, it takes a lot of manpower to manage. The real-time positioning system (Wi-Fi RTLS) can be used to realize easy management. The electronic tag has built-in or external sensors. The tag can collect the temperature, humidity, time and other parameters of the environment where the medicine is located in real time and upload it to the positioning server. The parameters can be set on the positioning server. When the environmental temperature and humidity of the medicine exceed the standard, the label will trigger an alarm reminder, and the manager can deal with the effective management of the medicine in real time according to the warning reminder information to avoid unnecessary waste.
5. Optimize workflow
1) Find a doctor instantly: The doctor wears an electronic tag, and the manager can see the doctor’s real-time location information on the back-end positioning server interface. When there is an emergency to find a doctor, they can send instruction information to the label through the positioning server. After receiving the reminder, I know that I have an emergency, and I can go back to the clinic immediately.
2). Ensure the safety of medical staff: If a medical staff encounters an emergency situation, such as being attacked by a patient, or unable to return to the clinic due to an emergency, the doctor can press the alarm button on the label to inform the back-end management center of his real-time situation.
In summary, the real-time positioning system (Wi-Fi RTLS) not only solves the problem of wireless network coverage in the hospital, but also realizes the intelligent office of wireless Internet access. The real-time positioning system based on Wi-Fi wireless local area network also solves the problem of the hospital’s wireless network coverage. Effective management of personnel and assets. The real-time positioning system (Wi-Fi RTLS) can be integrated with the existing information system of the hospital at the same time, which is more convenient for the intelligent management of the hospital.
