is then compared to the actual speed of the auto in the receiver logic. The data received is then

decoded and converted to a signal that will display the speed limit on the display panel, and a

separate signal is also sent to each of the output options, including the speaker and the L.E.D. If

the driver is exceeding the speed limit, he/she is notified appropriately.

In addition to being able to choose the means of notification of speeding, the driver is also able

to incorporate a cushion. This is a number of miles per hour by which the speed limit can be

exceeded before the alarms are enabled. This feature would not be part of the basic speed limit

alarm, but would be available as an extra.

Two major goals that were kept in focus while designing the alarm included a low production

cost and reliability. Should the alarm become more than a prototype, hundreds of thousands of

transmitters and receivers will need to be produced. In order for the product to be a success, the

cost of production will have to be low. Additionally, should the alarm replace or at least

complement the posted speed limit signs of today, accuracy and reliability are essential. Thelarger the role of the wireless alarms, the greater their need for accuracy, and this is true for

obvious reasons. In order to achieve a functioning product with these two considerations in

mind, the design of the alarm was kept as simple as possible.

Originally, the design of the alarm involved synchronous data transfer from the transmitter to the

receiver. A packet of bits representing the speed limit would be shifted to the transmitter at a

rate specified by an on-board clock, and then received at a rate specified by a clock amid the

receiver logic. Knowing that the two clocks would not always be in phase with one another,

which could and would cause a portion of the data to be inaccurate, an asynchronous design was

chosen. This design change, while having a major impact on the receiver logic, only minutelyaffected the original transmitter logic.

Literature review

The main components of the transmitter are a parallel-in/serial out shift register, two up/down

counters (Counter1 and Counter2), a J/K flip flop, and the Linx transmitter chip. Counter1

enables Counter2, which then enables the shift register to serially shift out its contents to the

Linx chip and be transmitted. Counter1 then disables Counter2 and hence the transmitting

process, allowing time for the signal to be received and processed by the receiving end, and the

cycle begins again when Counter1 enables Counter2. This process continuously loops,

alternating between transmitting and resting for as long as power is supplied to the device.

Linx TransmitterThe data to be transmitted enters the Linx transmitter chip serially and is then

transmitted.

Code The speed code was chosen with efficiency and reliability in mind. Since the

transmitting and hence the receiving period (and consequentially the speeding/not speeding

update time) depends primarily on the length of the speed limit code, a code was chosen that

would minimize the operating period and still transmit the number of speeds necessary.

The receiver logic portion of the device was implemented using basic logic principles and

components. The receiver logic used three counters, two comparators and various simple logic

devices to implement the desired function. The data input from the receiver module had to be

used as both a control signal and a data signal. The initial design attempt involved using a serial

in parallel out shift register which would need to be clocked from the receiver board itself.

Objective

This proposal comprises the following general and specific objectives:

General objective: to make the automobile deriving experience safer and more convenient.

Specific objectives: some of the specific objectives are:

Successfully link the transmitter/receiver pair and limit the distances that the transmitter

will transmit to avoid crossover with other speed limit transmitters in the area.

Successfully integrate the speedometer with the data from the receiver by the use of a

micro-controller.

Allow both the speed limit sign and the speedometer alarm to remain adjustable to the

users sensitivity needs.

Methodology

Literature review: includes reading books, articles, simulation tools and other materials related

to wireless communication and programming that helps me in doing this paper.

System modeling: involves formulating mathematical relationship to achieve optimum values.

Simulation: simulating performance evaluating parameters in order to outline the significantimprovement.

Analysis and interpretation of the results: different performance improvement will be

analyzed and interpreted by numeric parameters like how much and if present possible tradeoffswill be mentioned.
