Advanced Public Transportation System APTS/ Intelligent Transport System

One application implemented in APTS area is GPS vehicle tracking system in public transport buses (Bangalore, Chennai, Indore) to monitor vehicle routing and frequency .so that passengers do not have to wait long hours for a bus. .The objective is to provide Global Positioning System based passenger information system to help passengers utilize their waiting time at bus stops more efficiently as well as to reduce the uncertainty and associated frustrations. Display boards with high quality light emitting diode in wide-view angle are provided at bus stops so that passengers can read the information. It displays the number and destination of the approaching bus, expected time of arrival, and messages of public interest. Even SMS Alert is provided to the Ticket reserved passengers from Main server Applies state-of-art transportation management and information technologies to public transit systems to enhance efficiency of operation and improve safety. It includes real-time passenger information systems, automatic vehicle location systems, bus arrival notification systems, and systems providing priority of passage to buses at signalized intersections (transit signal priority).

10.Multipoint Wireless Data Acquisition System for Smart Vehicle

In data acquisition mode ARM-7 microcontroller acquires and stores different parameter of car. The main block of Wireless Data Acquisition System for Vehicles is ARM-7 micro controller which is heart of the WDASV which provides monitoring and controlling actions. It senses signals from input blocks and processes output blocks. The software program is stored in ARM-7 microcontroller on chip memory, according to which it provides the controlling actions. The on chip ADC converts these parameters into digital form and gives to the ARM-7 microcontroller. The status of door status i.e. whether the door is opened or closed is sensed by door status block and gives the corresponding signal to micro-controller. The speed of the vehicle is sensed by the speed sensor and this speed is measured in RPM by ARM-7 microcontroller. With the help of keyboard block the driver can enter the password along with cabin temperature. The LCD block is provided for visual display of the message and password. Also it continuously displays the measured parameters. The RTC provides real time clock depending on which the various events occur. Whenever accident takes place the accident interrupt block gives interrupt to the ARM-7 microcontroller. Through serial communication block the WDASV is interfaced the PC. With this interfacing the stored data is transferred serially to PC, for the analysis purpose.

11.Microcontroller based anaesthesia machine

In the hospitals when any major operation is performed, the patient must be in anesthetize condition. If the operation lasts for a long time, say for suppose for 5 or 7 hours, complete dose of anaesthesia cannot be administered in a single stroke. It may lead to the patient’s death. If lower amount of anesthesia is administered, the patient may get up in midst to avoid this, the anesthetist administers few milliliters of anesthesia per hour to the patient.

If the anesthetist fails to administer the anesthesia to the patient at the particular time interval, other Allied problems may arise.To overcome such hazardous problems the design of an automatic operation of an anesthesia machine based on a micro-controller is effective. In this system provided syringe infusion pump along with the microcontroller .

The anesthetist can set the level of anesthesia in terms of milliliters per hour to administer anaesthesia to the patient. After receiving the signal from the temperature sensor heart beat sensor and respiration sensor , the microcontroller controls the signal to the desire level and fed into the stepper motor to drive the infusion pump in proper manner. The anesthesia is administered to the patient according to the stepper motor rotation.

This particular paper will be very much useful to physicians to see the current position of anesthesia of the patients. If the level of anesthesia is decreased to lower level (set value), the alarm will be initiated to alert the physician to refill the anesthesia in the Syringe Pump to continue the process
