Automation in patient room for covid 19 in hospital
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryThe number of patients worldwide is increasingly rapidly due to COVID19. Caring for and supporting these patients is a concern for families and hospital staff around the globe. Patient’s room automation is one of the fast growing industries that have the capability to change the way people live. The aim of the automation of patient room in hospital is to provide a system to the patient that responds to their smart phone and control the on/off status of electrical appliances such as control over lighting, fan, window blinds, bed position, gas leakage room temperature, also nurse or attendant continuously monitor the blood pressure of the patient and call an attendant or nurse from their smart phone. To gain maximum the system must be easily configurable, easy to run and reasonably cheap. The series of topics discussed are how to make patient’s life safer, more comfortable and convenient.
Project ObjectivesFollowing are the objectives of this project:
- Adds safety through emergency alarm alert.
- Monitoring of patient room.
- Smart hospital through IoT.
- Increases awareness through security cameras.
- Increases convenience by monitoring temperature and humidity.
- Saves times.
- Saves money and increases convenience for patient’s family members.
- Facilities for doctors to monitor the patient.
- Proper monitoring of temperature and heartbeat through cloud.
The processs that are automated in this project are:
- Lights & fans control.
- Smoke and gas leakage emergency alert.
- Window blinds control as electric curtains for semi private room.
- Patient bed movement control.
- Monitoring of room temperature and humidity.
- The monitoring of the complete process will be done through mobile app or website.
The main hardware component in the system is the microcontroller Raspberry Pi various sensors such as temperature sensors, light sensor, relay, web camera, and step motor. It is a general overview of the control and monitoring system of the patient room. The application of the components which are found in it can be explained as follow.
Raspberry Pi in this system used as the center of data processing which is received from other components. Raspberry Pi receives input data from sensors, which then the raspberry pi gives output command to perform the certain task. The data that have been received by Raspberry Pi will be continued to the server through the internet. The webcam in this system is used to monitor the patient's room condition. The data or recording sends to the cloud and monitoring through a website or HMI touch panel. DC gear motor in this system is used to the movement of patient’s bed and window blinds as movement of motor in clockwise direction it will move downward while the direction of motor in anticlockwise it will move in upward direction which is controlled by the users through smart phone. Temperature sensor in this system is used to measure the room temperature. Gas and smoke sensor is used to detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. LDR is used to energy efficiency sensors to lower electric bills.Relay in this system is used to control the movement of bed and window blinds, lights and fan in patient room.
- Smart patient isolation room for COVID19 patients.
- Installs easily in the existing network.
- Economical.
- System stability.
- System reliability.
The main components which can be used in this project that make patient’s life safer, more comfortable and convenient are:
A. RASPBERRY PI:
Raspberry Pi in this system used as the center of data processing which is received from other components. Raspberry Pi receives input data from sensors, then gives an output command to perform certain tasks. The data that have been received by Raspberry Pi will be continued to the server through the internet.
B. WEBCAM:
Webcam (web camera) is the name of real-time camera which the image can be seen
through WWW (World Wide Web), fast data processing program, or video call application.
C. PATIENT FALL DETECTION SENSOR:
A load cell (or load cell) is a transducer that converts force into a measurable
electrical output.
D. TEMPERATURE SENSOR:
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the
surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It’s fairly simple to use but requires careful timing to grab data.
E. GAS AND SMOKE SENSOR:
The Grove - Gas Sensor (MQ2) module is useful for gas leakage detection
(home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. The sensitivity of the sensor can be adjusted by a potentiometer.
F. DC GEAR MOTOR:
DC Gear motor is also called DC Geared Motor, Geared DC Motor, and gearhead motor or gearbox motor. It consists of an electric DC motor and a gearbox or gearhead these gearheads are used to reduce the DC motor speed while increasing the DC motor torque. Therefore the user can get the lower speed and higher torque from the gear motor.
G. WIFI MODULE:
The ESP8266 WiFi Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all WiFi networking functions from another application processor.
H. LDR:
Light-dependent resistor (LDR) or photocell which is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity.
I. INTERNET:
Internet is used as a data sender media who received by microcontroller Raspberry Pi to the server.
J. WEB SERVICE:
Web service is an application of the server that is used to receive the data that has been sent by microcontroller Raspberry Pi and then save it in the database.
K. DATABASE:
The database is used to save the data collection received by the server.
L. WEBSITE:
Website is used to control and monitor the sensors data, patient movement, emergency alarm alert, lightening, fan, and window blinds.
