INTRODUCTION
1.1. PROJECT OBJECTIVE
In this chapter introduction of the PATIENT MONITORING SYSTEM TO REMOTE DOCTORS USING GSM AND ZIGBEE TECHNOLOGY are discussed. It gives overall view of the project design and the related literature and the environment to be considered. Chapter wise organization of the thesis and the appendices is given at the end of this chapter. At first we discuss the main processing done using 8051 microcontroller is and then what is the process that can be automated which is within the scope of the work. Then we discuss the implementation aspects.
1.2. OVERVIEW
In case of emergency and dangerous situations we have to alert the doctor immediately. For this we are using a Zigbee based network for doctor to patient communication in the hospital and even to communicate and indicate the status of the patient through SMS. This way of communication is actually done with Zigbee network topology and with the GSM network. Each patient will be given this module and with the help of this module the patient health condition is monitored and if there is any change in the condition of the health then it immediately sends that changed data through Zigbee to the local system where the main module is connected to the computer to maintain the status of the patient.
The heart beat is monitored with the pulse rate of the body. The high intensity light sensor senses the expansion and contraction of the heart with the help of the nerves. That beam will transmit the signal to the receiver and the minute change in the pulse is noticed as the heart beat. If there is any change in the pulses then it is noticed as the change in the heart and then the controller will get a disturbed pulse count which indicates the fault or malfunction of the heart. The controller is fixed for a no. of pulses initially. If there is any change in the any of the pulse count then it considers as a malfunction of the heart and then it transmits the pulse count with the patients ID to the doctor in the hospital and at the same to it sends a sms to a fixed number in the microcontroller. This is convenient process to monitor the patients health conditions form any of the distance we present. Since we are using both the networks like Zigbee and GSM this makes the user to communicate for internal system and as well as to the longer distances.
1.3. AIM OF THE PROJECT
The main processes involved in this type of control system are to monitor the patient’s health status. Zigbee is a wireless connection network that is used to connect different devices at a frequency of 2.4GHz. For medical applications also this Zigbee is widely used. The Zigbee can communicate with the devices of about 1km. The other network is GSM network. This can be operated from any distance to any point of control. The communication is done with the help of local network support. This can get communicated to any part of the world which the network of the local system is applicable. Here we are using for the hospital communication for monitoring the patient.
1.4. LITERATURE SURVEY
The technical brilliance and development in different fields has led to a drastic in our lives, one among them is embedded systems. The application of these devices is to monitor the patient health status. Zigbee is a wireless connection network that is used to connect different devices at a frequency of 2.4GHz. For medical applications also this Zigbee is widely used. The Zigbee can communicate with the devices of about 75 m. The other network is GSM network. This can be operated from any distance to any point of control. The communication is done with the help of local network support. This can get communicated to any part of the world which the network of the local system is applicable. Here we are using for the hospital communication for monitoring the patient.
