Accident Alert Using ZIGBEE and GPS

Abstract : The Internet of Things is a network of physical objects embedded with electronics, software, sensors and network connectivity that enable these objects to collect and exchange data. Currently, when an accident occurs, either the victim or the witness has to inform the local law enforcement and call the ambulance for help. This manual process causes a lot of delay inproviding assistance to the injured person(s). To reduce this delay, we propose an automated system that sends an alert message to the law enforcement in the locality of the accident and also to the ambulance, as soon as the accident occurs, so that help may be provided as soon as possible. For automating this process, we make use of the vibration sensor in the car and ZigBee for transmission of information. The vibration sensor is activated when the accident occurs which, simultaneously activates the PIC, which contains the information regarding the vehicle, and the GPS, which, obtains the location of the accident. This information is loaded into the ZigBee transmitter, which transmits it to the ZigBee transceiver from where it is sent to the server via aLAN (Land Area Network) connection. The server then searches the database for emergency contact numbers pertaining to that location. An SMS gateway is then used to send the alert message to those numbers. The outcome of this system is the automatic and immediate alert to the local law enforcement and ambulance about the accident.

 EXISTING SYSTEM :

 ? There no existing system is available to track the vehicle, which made accident using the regular monitoring system. ? Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. ? In the existing system, when an accident occurs, either the victim or the witness has to inform the local law enforcement and call for an ambulance manually, hence there is a huge delay before help could arrive. ? If the location of the accident is remote or if the accident occurs during late hours of the day, there may be no witnesses and the victim may be seriously injured and unable to call for help.

 DISADVANTAGE :

 ? The motorcycle accident is a major public problem in many countries. Despite awareness campaign, this problem is still increasing due to rider's poor behaviors such as speed driving, drunk driving, riding with no helmet protection, riding without sufficient sleep, etc. ? The immediate effect of this situation is the dramatic increase of traffic accidents on the road, representing a serious problem in most countries. ? It can overcome the problems of lack of automated system for accident location detection. ? One of the drawbacks of this system is that cameras are placed in limited areas only.

 PROPOSED SYSTEM :

 • In the proposed system, when an accident occurs, the in-built vibration sensor is triggered which, in turn activates the PIC and the GPS. • The PIC contains information regarding the vehicle. • The GPS, when activated, obtains the position of the car in latitude and longitude format. • These particulars are loaded into the ZigBee transmitter which transmits this information to the ZigBee transceiver that sends the information to the server which employs an SMS gateway to send an alert message to the emergency numbers pertaining to the location of the accident by searching the database.

 ADVANTAGE :

 ? The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit. ? The main advantage of using ZigBee for the transmission of information regarding the accident is that ZigBees may transmit even in remote areas and do not require any GSM network for transmission of the data. ? It is used access the vehicle by swiping the card in the device. ? When the accident occurred, information of the driver can be stored in the microcontroller by using embedded c language and passed via zigbee communication to the server.
