Design and Implementation of Wireless Nurse Calling System Using SYSCALL

The proposed system architecture is shown in “Fig. 2”.

The figure explains the main idea of the system where nursing staff can reply to the patient by knowing his room and his bed number via an easy graphical computer interface. The proposed system uses simple (WSN) and can be expanded. In this project do not use the sensors to monitor the environment or temperature measurement or other functions that can be used for it, just its use a signal coming from the push button.

The architecture of the system is based on wireless communication and (plug and play), this allows to expand the network by adding rooms or beds. The new bed is given an address and this address is added to Processing program to access the wireless network.

The system simply consists of two main parts , the master and slave parts. The master part is located in the main nursing room, and the slave part is near the patient’s bed (each bed has its own device). The master part consists of: the microcontroller (SYSCALL) connected to the wireless module, two LEDS
(green & red) and push button and a computer device.
The slave part consists of: the microcontroller (SYSCALL) connected to the wireless module, two LEDS (green & red) and push button,
