The traditional wired bed call system is not only costly but also less efficient. In this paper, research on bed call systems based on AT89C52 microcontroller is carried out. The nurse-side host (AT89C52) and the bedside slave (AT89C52) communicate over long distances using wireless communication technology. The system transmits signals, including Liquid Crystal Display (LCD), voice announcements, and beeping alarms, to indicate the bed number requiring assistance. This allows the nurse to respond promptly. The system supports real-time updates, where calls and processing occur independently, ensuring efficiency. It is not only cost-effective but also enables a rapid and intelligent call-and-response process.
