DE102005035714A1 - Direct information system has transmitter provided in emergency vehicle, and keyboard for inputting of text messages, where transmitter transmits inputted messages to receiver and some keys of keyboard are allocated with standard note - Google Patents

Abstract

The system has a transmitter provided in an emergency vehicle and a receiver for motorists, where the transmitter communicates with crash sensors of vehicles of the motorists. A keyboard is provided for inputting of text messages and the transmitter transmits the messages to the receiver, where some keys of the keyboard are allocated with standard notes. A potentiometer is used in the transmitter for adjusting the range of the transmitter. An independent claim is also included for a transmitter in an emergency vehicle.

Description

field of use

The The invention relates to a device for local traffic control by emergency vehicles of the appropriate authorities (inter alia) (police, fire brigade Etc.).

State of technology

So far use o.g. Emergency vehicles blue light and siren. This serves to warn the other road users and allows one faster advance or protection of a danger spot. Due to this technique, a direct communication of the forces be given with other road users. (Hearing or visual contact required). Also, more extensive messages are only very limited possible (public address systems with a short range! radio too large and will be activated not before place).

disadvantage of the prior art

The above describes communication technology between emergency vehicles and other road users is not the current traffic situation more appropriate.

By better noise isolation Of the vehicles, the siren is hardly or far too late to hear. The same applies if road users something loud music or the like Listen. Also the denser traffic than before and with the associated noise pollution has the same effect.

Would the forces not heard (silent alarm vehicles are only on the road with blue light) deleted the protective effect largely. Generally, the range is extremely limited-audible at best a few hundred meters, sound sources are difficult to locate. The Effectiveness of the blue light always requires visual contact. This is very often disturbed. For example, weather - fog, heavy rain, snowfall, road surface, bends, traffic islands, Trucks, neon signs, etc.

Also here the range is very limited.

Considered you're driving the speed with the emergency vehicles, is a real protective effect and a true traffic control almost locked out. Heavy traffic accidents are in this context to complain again and again.

Task of invention

optimal Communication of road users, independent external influences, greater range, depending on Demand can be adjusted (eg higher speed). Extended Messages (text and voice messages in all languages by Use of standardized formulations is a translation anytime possible! That A road user can always get a message in his native language read!!

So it is also possible the cause of a traffic jam (eg fire, flood, traffic jam, terrorist attack, etc.) communicate, which minimizes aggression, especially during longer waiting times become.

local Limitation (in contrast, for example, radio).

signal direction adjustable by an appropriate orientation - this has the advantage that only the road users are influenced, in their direction drive the emergency vehicles.

winding Routes are no longer obstacles.

weather conditions can considered become (longer Braking distance of vehicles in winter).

different Identification of emergency vehicles possible-police, fire brigade, ambulance, rescue services, Military vehicles Etc.

mute other noise sources in the car like radio, phones etc.

automatically Warn all road users of serious accidents by connecting a transmitting unit to the crash sensors of the vehicles. This will make the accident more accidental Vehicles relieved. It is also possible from a certain speed automatically send a message. This will be Lane changes on the highway considerably safer, as greater speed differences be displayed immediately.

example Description the patent application

The DIS consists of a transmitting unit in the emergency vehicle and a Receiving unit of other road users.

The transmitting unit has the possibility to enter messages via a keyboard. As a result, text messages can be transmitted, which can also be reproduced verbally by the recipient as desired.

Of Furthermore, standardized broadcasts by fixed key assignments z. B. F1, F2, F3 etc. available.

For example:
F1 = simple warning (police operation, fire brigade etc.)
F2 = keep center alley clear
F3 = change the traffic light setting (continuous red, green wave to the place of use)
F4 = Fire hazard, do not throw burning objects out the window
F5 = Ghost driver
F6 = accident etc.

• – Display zur Wiedergabe von Texten mit der Möglichkeit der Darstellung aller weltweit gebräuchlichen Sprachen. Zusätzlich ist eine Darstellung von Zeichen und Symbolen möglich.

The receiving unit has the following features.

• - Display for playback of texts with the possibility of displaying all the world's common languages. In addition, a representation of characters and symbols is possible.

Z. B. Illumination of a warning triangle alternately hazard information (Accident, traffic jam, fire, terrorist attack, gas alarm, etc.).

each Warning message is also accompanied acoustically and all other noise sources be stolen. This is done by an appropriate control a relay, the consumer like phone, radio, etc. with electricity provided.

In order to the message can be received in all languages it's a menu control in which one the desired Can select language.

As well is there a switch possibility with which one can hear the text messages also acoustically. This requires the Driver not on a display while As a result, the information is people as well who can not read accessible.

• 1.) Die Sendeeinheit wird durch eine variable Isolierung, die je nach Bedarf elektrisch hoch bzw. heruntergefahren werden kann.

Another Bestanteil the invention is the direction control of the radio signals and a transmission strength (range) by means of potentiometer. Direction control is possible in two ways.

• 1.) The transmission unit is provided by a variable insulation, which can be electrically raised or shut down as needed.

1

• 2.) The transmitting unit consists of four individual transmitting points, which are each mounted in the middle of each side of the vehicle. Depending on requirements, then either individually or together unlocked. ( 2 )

Of the receiver gets the news on a display.

Alternative:

Output of the information as a voice message through a speaker.

Of course you can This system also serves as a traffic aid system for road users use each other. So you can equip any car with a transmitter of in different situations automatically other road users informed.

By a corresponding circuit by connection to the crash sensors a motor vehicle in case of an accident), or connection to the speedometer transmitter (transmission the speed z. B. from a speed of 160km / h - see this other then either in the display or in the left side mirror. Lane change on the highway).

Claims (9)

Transmitting device in the emergency vehicle to send information and a receiving unit, characterized by a keyboard for entering text messages. 4 : Characterized in that a direct and extensive communication is achieved. By a fixed assignment of some keys of the keyboard, can Standardized characters can be sent without delay. Characterized is that the road users immediately react correctly - eg. B. on the highway - "Mittelgasse keep clear". By the nature of the message transmission (text messages, 3 ) the information is transmitted in writing. Characterized by the fact that misunderstandings at the receiver are almost impossible - Translations into all languages possible - Repetition of the message - Identification of the emergency vehicles (fire brigade, military, police) - an acoustic output remains unaffected. Use of a potentiometer on the transmitter unit, characterized in that the range of the transmitter adjustable is. Device according to one of the preceding claims, characterized in that the transmission signal by means of servomotor or design is given a direction ( 1 + 2 ). If at least two transmitters are used, one is Location of emergency vehicles given. Local transmitter in the emergency vehicle, characterized is that this type of regulation is almost completely insensitive is against external influences. Extension of the invention by the installation of a Transmitter in each vehicle to get vehicle data to everyone else To convey road users - such as speed, Full braking, standstill etc. - so is possible, that these data are from the recipients for warnings or automatic brakes etc. are used, characterized in that information not be measured by others but automatically communicated by the causer become.
