1. Significance of system construction
1) Real-time supervision and management of newborn babies in the hospital (the information center can view the position information of newborn babies, the number of babies, any baby information in the delivery room, baby dynamic changes, baby stolen alarm information, baby out of a fixed area alarm information, etc.).
2) Active early warning, solve the problem of lagging accidents, expose the hidden dangers of accidents in advance, and avoid accidents;
3) Sudden scenes reappear, the Internet of Things technology and existing video linkage can view the scene of the accident in real time, providing a basis for the deployment of relevant doctors to solve the emergency;
4) Reduce the workload of hospital nurse doctor management and improve work efficiency.
5) Improve the informatization level of hospitals, promote the institutionalization, standardization, and real-time development of hospital infant management to ensure the safety and stability of the delivery room.
2. System architecture and program description
In recent years, incidents of newborn babies being lost and stolen in hospitals have frequently occurred. Traditional baby monitoring and management is usually performed by manual care management methods that use visual recognition text, barcodes, and cards to identify. This management method is often easily caused by misidentification. The incidents of being exchanged and stolen have brought huge losses and impacts to the hospital and their families. Here we propose a brand-new basisRFID The technical application design of neonatal electronic anti-theft system, because RFID has the characteristics of long-distance non-contact fast and accurate reading, it is very suitable for reading and monitoring neonatal characteristic information.
2.1 System architecture
2.2 Program description
The anti-theft system for newborn babies based on semi-active RFID technology uses semi-active electronic tags, using electronic tags as the most advanced identification code at present, and installing them on controlled targets as the unique identification of the target for tracking and positioning. At work, managers use networked wireless identification base stations to track and locate targets.
The baby electronic wristband works in two modes: “active or passive”. The wristband emits signals actively or is triggered by instructions from a reader (or low-frequency activator). The activators distributed in various areas or inside and outside the access control have been actively transmitting 125KHz low-frequency electromagnetic wave signals at close range. The baby wristbands within the signal range of any activator can be activated smoothly, and the digital number emitted by the activator can be obtained. Calculate the RSSI field strength value. The baby wristband then wirelessly transmits data such as “tag ID + tag status information + activator number + RSSI value” at a frequency of 2.4 GHz.The long-distance reader antenna installed in the delivery room, entrance guard, and corridor receives the carrier signal sent from the anti-removal wristband, and transmits it to theReader, The reader demodulates and decodes the received signal and then sends it to the neonatal anti-theft system software based on semi-active RFID technology for related processing. The system judges its legality and location information based on logic.
