Abstract

A system capable of warning road users of the presence of emergency vehicles includes a radio transmitter onboard the emergency vehicle and a receiver aboard other road vehicles. Upon receipt of an activating signal from an emergency vehicle the receiving units will emit both visual and audible warnings. The warnings may be in the form of LED lights and buzzers. The transmitting and receiving units will use antenna.

Description

24 275 Emergency Control System

Introduction

The purpose ofthis project is to allow emergency vehicles to progress through their journey and reach their destination with ease without any delay caused by traffic and day to day congestion. Emergency personnel will benefit from this by a lot and also drivers - regardless of disabilities including the deaf will take advantage from this.

Method The product will be electronically operational through means of a radio transmitter and receiver. Each and every emergency vehicle will have a transmitter as well as a receiver installed and hard wired through the ignition system. As soon as the ignition is activated, a green light on the transmitter will flash in accordance representing stand-by mode. This will indicate that the system is fully operational, should any emergency arise.

In the case of an emergency situation, the emergency personnel can send out a signal to other motorists, alerting them of the situation at the touch of the button attached to the vehicle. This signal will only reach drivers who are within a certain range which is selected by a transmitter. This will work effectively wherever the emergency vehicle has driven to. By now the original green light will have switched over to a red flashing light showing the operator that the signal is pending. The signal can only shut off when the switch is returned to stand-by mode (green light).

Ordinary vehicles will have a factory fitted receiver as part of a compulsory law, should it pass. As the ignition is activated a green light on the receiver will begin to flash.

This indicates that the receiver is ready to use. In any case of an emergency, a green flashing light will switch to a red flashing light with the sound of an audio signal bleeping discreetly so that the driver is aware of the situation and so in turn, can act accordingly and clear the way well before the arrival of an emergency vehicle.

Diagram See attached document for illustration. )

Advantage Currently, emergency vehicles have great difficulty reaching their destination in a short time due to traffic congestion.

With the new system, every motorist will have enough time to move aside before an oncoming emergency vehicle drives through and in this way many lives can be saved in a short matter of time.

Suggestion All transmitter and receiver units will be sold through government departments and will become essential recommended installations through M.O.T stations nationwide.

Conclusion

There have been many methods that have been used on emergency vehicles such as flashing lights, sirens, and transmission through means of a satellite and telephone networks etc. All these systems are very expensive for government bodies to run throughout the country. Alternatively, the system that I have designed is sufficient, cost effective, and cheap. Every motorist can afford to have it installed.

PAGE 3, 1/4 Shows a practical method how the system wild effectively work.

In brief the emergency personell will transmit a signal Towards moving traffic on the road.

As shown on page 3. The moving traffic will clear their way For emergency vehicle well before its arrival.

Claims

1. An emergency radio frequency controlled signal transmitor (Tx) fig.1 and emergency Radio frequency controlled receiver (Rx) fig. 2 Device on coming and going away traffic On the road in front of emergency vehicles.

2. Acording to claim 1 a transmitor and receiver are permanently hard wired through Vehicles ignition system so that when ignition is switched on the transmitor and Receiver are automatically powered by 12V battery when ignition is switched off The transmitor and receiver are automatically powered off.

3. A transmitor unit according to claim 2 has one external push on manual switch 2 Fitted by emergency vehicles driver so that in case of emergency the driver Can operate this switch in order to alert traffic infront to clear there way Well before the arrival of an emergency vehicles the further away that the emergency vehicle is approaching more and more clear way the emergency personell will find up to there destination without speed dropping.

4. As in claim 3 the transmitor unit has built in BNC socket 3 in order too plug in antenna 4 So that the transmited signal can be sent out via antenna attached to a vehicles body externally.

5. The transmitor antenna 4 according to claim 4 will be fitted at top of emergency vehicle In middle front in order to send out emergency signal.

6. According to claim 5 the transmitor unit also have external alert unit 5 Connected to it so that when emergency signal is transmitting the other vehicles Drivers will be alerted that emergency vehicle is approaching behind Or infront of them.
