  now can anyone disscuss abu the circuit combination of this project

  Can't we use GPS in this?

  First of all, what an awesome idea!Concept is great but we have to find a transmitter which will stay intact in case of an accident. The next question that arises how do we propose to pin-point the site of the accident? I suggest a Microstrip antenna. The rest will need some more brainstorming. Will get back to you.

  ya of cos we ve to use gps.... to locate the accident ... but the point over here is that the way of transmitting the msg to other vehicles... the idea of using microstrip antenna is good... but we ve to use an transreceiver.... coz the vehicle which is receiving the ve to pass on the signal to other nearby vehicle in case if it doesn't find the base station(hospital,ambulance etc..) near by.... so a combi circuit and programming to do all these....
  ?
  of cos brainstorming is needed........... 😛

  What if there is no other vehicles nearby in range to rebroadcast the packets? 😛

  Thats why i had suggest to use GPS as it is more reliable. 😀

  Actually, as jaywalker mentioned, GPS should be used anyway for location aquisition. But thats all that GPS does, it doesn't transmit its own coordinates out. We'd still need to transmit this information out, hence this proposed wireless system.

  arey yaar... it can detect the vehicles in around 200m... so no point in thinking abu no vehicles... 😛
  more on we gonna implement it on remote highways...

  Yes, Then its good !
  
  You just have to find out the Suitable RF Modules. And there are some good options from TI and HOPE RF for Wireless Solutions.

  jaywalker

  TI and HOPE RF ?...can u just explain the option of these things

  I mean they are manufacturer of RF Modules for wireless communication.

  First of all, we'll have to establish a given frequency at which all the transceivers will be tuned or rather a given freq. band. Logically the transmitter will have to multicast the alert packets. The vehicle which is 'farthest' away in the given transmitting range will send an acknowledgement confirming retransmission to the nearest base station. The signals from a base station like an emergency response center can be differentiated from those from another vehicle by some bit field in the packet format. The rest needs to be developed more. And we can use the Fm antenna in the vehicle for this purpose too. What say?
  @jaywalker- Plz. don't use short from of the words & don't use any other language than English. Better edit your post before catching the moderator's eye.

  hey can u ppl temme how to assign unique ID's to an transmitting nd receiving units.... nd also tellme anything about the collision sensors u know... nd even how can we make use of electrode for collision detection..??

  For Collision detection i think you can use Ultrasonic Sensor.
• 

  jaywalker

  ya ok with ultrasonic sensors... but what about using electrodes for sensing collision... do you know anything about it..?
  and tell me about the assigning of ID's for the transmission units...

  Don't know about electrodes. 😔
  and for assigning ID..you can use PROTOCOL. it mean you have to program all the device with Unique ID and some RF modules have facility to write address in their register.

  do anyone know about the way of transmitting the gps contents , i mean the gps location from one node to another.... the nodes here are dynamic...........

  I have one idea..if GPS is connected to your Device(CAR) then take the Data from that module and transmit it to RF module.

  but i think the gps resolution in india is too less.... and moreon is it possible to combine zigbee module and gps module to a single microcontroller?
• 

  Ashraf HZ

  Yep. If your microcontroller has only one hardware UART, use that for the zigbee and a software UART for the GPS. Watch out for the GPS buffering though! 😀
  
  Have you tested GPS in India? 10-15m accuracy should be good enough for this purpose.

  jaywalker

  cool.... will try out anyway.fine if u can, tell me about the code program for serial interrupts and external interrupt....?

  thanks all project is almost done... :-D

  thanks all project is almost done... :-D

  Great So now we are looking forward to see the Presentation here mate. please do share.

  jaywalker

  sure gonna post all my project details ...sorry for being late.. busy with certain works.

  If you are gonna implement this on remote highways, i have one question for you?
  What if there are no vehicles in and around 200m range as you said??
  I would also like to add a point why dont you set up these transmission stations along the road, like cell phone towers. In this case using a high power transmitter we can broadcast the details and the location of the accident directly to a nearby Hospital/ambulance or other emergency services.
  
  This is just a thought which came across my mind.
• 

  jaywalker

  no the first preference will be given to hospitals in case hospitals found as soon as accident occured then the message is directly passed to it else via passing by vehicles.. then its a good idea to implement it on road pedestrian lamps, towers.. etc.. we had thought but since we made prototype for our college project work we didn't go for it..thanks for your suggestions bob...
• 

  jaywalker

  then we changed title of project as "Automatic Accident Routing System"(AIRS)... :-D
• 

  jaywalker

  sorry it was Automatic "Accident Information Routing System"... 😛
• 

  dheerajkvs

  Yes that is something like i thought..
  Anyways i think that it is better to depend on these lamp posts than passing vehicles as only god knows when the next vehicle is gonna come in that way.
  Going for these towers along the road makes the project more reliable than when depending on passing vehicles.
  Anyways all the best....
