Assignment Help:
I am the inventor of the railway signaling device now operated by timer. I wish to move on to the next phase where the equipment will be operated by DTMF codes. The device is a signaling device for railways to protect work crews working on the track.

what I need the design capability for is to perform the following actions using radio signals and initiate 4 actions. The actions can be described as follows
1- create a source of a DTMF code from radio with a minimum range of 3 miles to initiate remotely the display of a certain color signal to indicate to trains that a crew is working on the track. the portable signaling device will then initiate the movement of the flag (much like s sjicece of bread coming out of s tosster) into the displayed position. this is a mechanical process now initiated by timer. Once the signal is then displayed position it ,toggles a limit switch on the display mechanism which initiates step 2.

2- Step two is that the signaling device sends a radio signal back to the initiating radio indicating that the flag is in display position this could be any special code or computer-generated voice reply. Example"flag is now in display position"

3- at the end of the work session the operator sends a DTMF code the flag device which initiates the mechanical movement of the flag back to the non-display position. at the end of the movement a limit switch initiates action 4.

4- this step is the reverse of step two where the signaling device sends a message back to the radio of the operator to indicate that the flag is now in the non-display position.

The particular challenge that I have is to come up with the system that operates independently and does not interfere with current DTMF code operated equipment on major railways within the US rail system. I need to have 4 of these units operating within 4 miles for each operator. The control radio will thus need to have a minimum range of 3 miles.



where would I need to go to get the design capability on cost sensitive budget to work with me to advance design of this control system as above.
