Design of Wireless Sickbed Call System Based on Microcontroller
With the development of technology,the application of wireless technology has been applied to every corner of daily life and production.The hospital bed call system is generally used in places such as hospital wards and sanatoriums.It is a device for patients to send call signals to medical staff to improve the level of hospital care.Designing a wireless hospital bed call system has certain practical application significance.The hospital bed call system uses STC89 C51 as the control module,nRF24L01 as the wireless sending and receiving module,and is equipped with corresponding power circuit,LCD display screen,button circuit,and sound and light alarm.The system is mainly divided into two parts:the host and the slave.The hospital bed number signal is collected by the slave machine and sent to the host.The host receives the signal,and the buzzer and LED emit an audible and visual alarm,prompting medical staff to call a patient.Then,the medical staff presses the response button to cancel the response,achieving long-distance transmission.
