Signal Analysis and Monitoring Systems Robotics Engineering
Biography
Many new parents have a fear of sudden and unexpected death for their child may they considering the use of a monitor to detect the possibility of cessation of breathing in order to make something and help their baby before it is too late. So in this project, we are focusing on transmitting the alarm by FM transmitter to alert the health care (parents) in order to take appropriate action.
Infants are at serious risk of suffering from an apnea while they are sleeping. The definition of apnea is a pause in breathing. When this pause lasts for (5-7) seconds or more, medical attention should bring to the baby. While adults take about 15 breaths per minute, a baby will take between (20-40) breaths per minute. Therefore, if a baby does not breathe for 7 seconds this is a serious problem that eventually could lead to asphyxiation; (Oxygen starvation of tissues). Chemicals such as carbon monoxide prevent the blood from carrying sufficient oxygen to the brain and other organs. As a result, the person may lose consciousness, stop breathing, and die without artificial respiration and other means of elevating the blood oxygen level). And idea should appear on surface to face this problem.
The project has four parts; at first electronic part that contains implantation of different circuits with different functions to form breathing monitor then we have a pic microcontroller unit (MCU) with LCD part which showing data. In addition, the part represents the most important function is wireless FM transmitter/receiver part, and finally to simulate the reality we have mechanical part includes a doll which mimics the natural baby.
I designed a device that is used to monitor the breathing rate of a baby.
Over many years this idea was implemented in different techniques and has encountered many developments in the size, communication technique between the baby bed and the Health care (parents), Sensor type…etc.
By, using the FM System is enough to send the alert signal to avoid high-cost communication devices. Microcontrollers are capable of storing and running the program that was written, compiled and downloaded onto it.
The digital display will be a liquid crystal display (LCD) connected to the Microcontroller, it displays the breathing rate(BPM), and breathing level as a percent(%).
The circuit of the baby breathing monitor device is composed of five stages; power supply
with a regulator, detection stage, an unbreathing alarm circuit, microcontroller with LCD and finally FM transmitter and receiver.
The power supply requirements were (+9) volts for some stages {detection stage, FM transmitter and receiver stage}, however, some stages need less than 9v precisely 5v so we use the voltage regulator (7805).
In this stage we use slider resistor as a detection tool for breathing signal from the baby, Then we connect it to Wheatstone Bridge to convert the displacement movement generating from inhalation and exhalation to electrical signal (voltage).
To transmit the alarm generated from the MCU we use an FM transmitter to propagate the sound signal in order to reach the receiver. This mechanism ensures safety phase to the baby guards that any breathing healthy problem or cessation will make an alarm allowing them to rescue the baby before it is too late.
