1. System background
Newborn babies are born in the hospital every day. This new life is the most valuable asset for every family and parents. However, the newborn babies have similar appearance characteristics and lack the language and understanding ability to communicate with the outside world. According to the statistical report of the medical department, incidents of miscarrying and stolen babies in maternity hospitals occur from time to time. These incidents not only cause serious trauma to the person’s mind, but also damage the reputation of the hospital, and even face lawsuits and financial compensation. The IOT rfid baby identification and anti-theft system is safe and reliable. It not only has comprehensive area monitoring, including real-time location and tracking functions of tags and regional location of events, but also has a fast response speed to alarm events. Therefore, in terms of newborn management, the hospital can not only monitor the location of the baby wearing the anti-theft tag in real time, track and record the baby’s movement, which can more effectively implement monitoring and protection, and when an alarm event occurs, it can also immediately locate the event. The location of the occurrence can prevent the occurrence of theft in time, thereby helping to protect the safety of the newborn and prevent the baby from being held by mistake or being stolen.
2. System principle
Babies and mothers wear wristbands. The baby wristband contains an active long-distance RFID tag, and the mother’s wristband contains a source short-distance RFID tag. Once the baby’s wristband is worn, if it is removed, its active tag will be An alarm message will be sent through the system. And the wristband has a waterproof and moisture-proof treatment. The active RFID of the baby is used for the system to identify its range of motion, and the hand-held card reader for close inspection of the baby and the mother can intuitively identify the pairing relationship.
In terms of the number of wristbands, several pairs can be made according to the number of rooms in the mother-infant room and the number of beds, (each room can be set with multiple pairs, and then some additional temporary pairing cards can be set to meet the situation of insufficient rooms and temporary arrangements). Recycled and reused, or sold to family members as a souvenir when discharged from the hospital; in terms of appearance, the wristbands paired by mothers and babies can be designed to have the same shape and color, so that the wristbands of different mothers and babies can be easily distinguished in appearance; In use, before the system is used, the wristbands used by the mother and the baby are set up in a pairing relationship, and the child is born with the wristband until discharged from the hospital.
Arrange card readers in the activity space to collect baby information. Install locators in each room where the baby is located (distance adjustable, 3-8 meters), and install long-distance card readers (distance 20 meters) in the corridors. Each baby’s wristband information will be automatically uploaded to the application software management subsystem for data processing; the important peripheral channels are designed so that only authorized personnel can enter and exit. To the greatest extent, prevent irrelevant personnel from entering and leaving casually.
Three, system function
1) Real-time location of baby area: It can locate the area where babies and medical staff wearing location tags are located in real time, and display them on the map of the monitoring terminal.
2) Regional baby population statistics and electronic roll call: real-time statistics of the number of babies that should be in each region and the actual number of babies, and prompts the name or number of the baby who has left.
3) Baby search: You can enter the baby’s name or tag number on the monitoring terminal to find the current location of the specified baby or the baby’s mother.
4) Disappearance alarm: It can focus on monitoring some babies. When these tags leave the designated area or disappear, the system will find corresponding alarms
5) Cross-border and exit alarm: Some areas belong to important areas, such as certain staircase exits, corridors or hospital gates. When unauthorized tagged babies or medical personnel appear in these areas, the system will issue an alarm. It can also be set in certain areas that certain babies are not allowed to leave the area within a set time, leaving or disappearing the system alarm, such as a baby room.If the baby leaves the room without authorization, the system will alert
6) Detention time over and alarm: certain special areas can be set. When a baby or mother stays in this area for more than a certain time, the system will alarm. By preventing some accidents from happening.
7) Track playback: You can query the movement track of a baby in a certain period of time in the past, and which areas the label has been to during this period of time.
8) Video linkage: You can bind a camera to each positioning device, and click on the map of the positioning device on the map of the monitoring terminal to call the video of the area where the positioning device is located. When there is a specific alarm, the system will automatically call up the video of the area where the alarm occurred.
9) Temporary label authorization: When a baby needs to temporarily enter an important area, or the baby wants to leave the nursery temporarily, a temporary authorization can be made in the system to allow him to enter an important area or leave the nursery for a certain period of time.
10) Electronic tag failure alarm: The failure of the electronic tag mainly refers to the low voltage of the tag battery; the wristband worn on the baby is damaged or removed; as long as the wristband worn on the baby is taken off, the system will prompt an alarm ; Whether it is cutting or removing it normally with a tool, the system will give an alarm. The system will also prompt when the battery voltage of the label is too low, and the battery needs to be replaced as soon as possible.
11) Personnel service call: There are function buttons on the specific card-type positioning label. When the mother has service needs or encounters danger or needs help in the situation, just press the function button, the system will display the location of the help, and call the nearby Camera video.
Four, system characteristics
1) Prevent the baby from holding the wrong baby
When the mother and baby’s wristbands are paired, the doctor can hold the hand-held reading terminal device to read the mother’s and baby’s wristband tag information respectively to verify the correctness of the pairing of the two wristbands. If there is no match, the reader will prompt the mother to let the mother Completely rest assured that it is indeed his own child. It avoids family and hospital lawsuits caused by holding the wrong baby.
2) Prevent malicious exchange of babies
The baby wristband is designed for one-time use. Once the wristband is worn, it will be invalid when it is turned on again, and the system will alarm. This prevents the malicious exchange of babies and avoids possible disputes between the hospital and the patient.
3) Prevent theft of babies
In the few days from birth to discharge of the baby, except for special circumstances, both the mother and the baby will stay in a specific monitoring area, where the system detects a safe area. Once the baby is stolen illegally (without authorization to take the baby out of the safe custody area), the system will immediately report to the police.
4) Control personnel access
The personnel entering and exiting the area are controlled. Those without authorization can not enter from the gates of the periphery of the area. Those with authorization can also set different time period restrictions for entering and exiting, and restrictions on the number of times. To the greatest extent, the hidden dangers caused by the entry of idle personnel are eliminated.
5) Prevent cross infection
The resistance of newborns and mothers is weak, avoiding the entry of unrelated persons who are idle, that is, a safety guarantee for mothers and babies, avoiding cross-infection and so on.
6) Retrospective query of events
The system will automatically record small areas of baby activities, entry of medical staff and parents, alarm events, etc., to provide a basis for subsequent inquiries.
7) Generate income for the hospital
8) Improve the image and management of the hospital
