Abstract

Transmitter for emergency response vehicles and level crossing allowing during a road intervention or the passage of a train, to have an interaction on the sound devices that equip road vehicles (cars, trucks, etc.). ) by sending a "silence" and / or personalized message in order to make their siren better heard and thus allowing a faster and more secure clearance of the traffic while evading the increase of the sound level of the sirens, or to warn of the lowering of the barriers of a railway crossing and the passage of a train.

Description

       

  1. Description

  
Title: Transmitter of Silence and / or Personalized and / or Free Messages for Vehicle Emergency Response and Crossing.

  
More and more motorists are more attentive to the listening of their radio than attentive to the sound signals emitted by the emergency services in operation (firefighters, ambulances, police vehicle, civil security, etc.). ) and the events and danger of the road.

  
The resulting consequences are, of course, well known and can go well beyond the stage of a simple intervention delay and often dramatic in the case of level crossings.

  
This problem, we had apprehended for some time and after studies and researches we have developed a fairly simple technical system that provides a real solution without requiring you to resort to an increase in the sound level of sirens and other alarms. emergency and which in the case of crossings without being able to solve everything already brings a great security and especially a foresight increased.

  
This system called MOR (c) (Mute On Request), is based on the momentary interruption of the sound (radio / CD / GPS / Hands-free) in vehicles of motorists at the approach of an emergency vehicle operating its siren or at the activation of the lowering of the barriers of a level crossing or the activation of signals signaling the passage of a train.

  
Based on the principle of the Mute, any system car radio / CD, etc. capturing a specific signal on a particular frequency coming from a siren in action and in a configurable radius puts itself in the situation of receiving a silent or personalized message, this message taking control over the sound received previously.

  
When the emergency vehicle is moved away from the transmission radius, or the end of the lowering of the barriers, the radio / CD units, etc. automatically return to normal function.


    

Claims (1)

2. Claim This system is based on the planned basic resource exploitation in the RDS / EON system of current car radios. The transmission frequency of the MOR system is in the FM band. The emission powers involved are chosen so as not to disturb the local radios. We limit ourselves to a transmission about a hundred meters ahead of the intervention vehicle. MOR 05: the equipment sends in the FM band a digital and vocal RDS-TMC signal  Silence message  Mermaid  Pre-recorded message  Voice message of release or prevention  etc. at the front of the intervention vehicle according to a diffusion angle and a configurable power, in order to facilitate its movements in an urban environment. The device (dimension +/- 10x15x4 cm) transmits the signals either on request or in synchronism with the siren of the vehicle. It is placed at the front of the emergency vehicle near the windscreen without specific wiring, it is powered by rechargeable batteries and / or cigar lighter and incorporates a directional antenna. It includes an off / on switch, a USB input for connection to a PC to perform frequency and power settings and software updates. A swich also allows the choice of the type of signal (message). It is equipped with a microphone input to enable the sending of voice messages on demand. Here again the efficiency of the transmitter is such that it will have influence only in the predefined range of action and as it moves, releasing the car radios from its influence during its removal . These signals meet the standards in force and will have the power required to cover the distance required for the passage of the vehicle. Car radios interpret them as road signs and mute (radio / cd / gps) and / or dock on a defined HF channel to receive traffic clearance information. The RDS-TMC modulator sends all the codes in use so as to concern a maximum of receivers. Advantages :  No additional equipment for the motorist  No installation or specific connection.  No necessary collaboration with broadcasters. MOR Tl: The equipment installed on both sides of the crossing sends a digital and vocal RDS-EON-TMC signal to the FM band:  Pre-recorded voice / pre-recorded message  Message signaling the lowering of gates and / or passage of a train  Any other message or warning sound According to an angle of diffusion and a parameterizable power according to the disposition of the places. The device (dimension +/- 20x15x10 cm) transmits the signals either on request or in synchronism with the activation of the barriers and / or the activation of the lights. It attaches to any existing pole near the barriers. It is powered by connection to any existing electrical connection and a connection triggered by the mechanism of the barriers and / or lights. It incorporates a directional antenna. Here again the efficiency of the transmitter is such that it will have influence only in the predefined range of action, re-freeing the car radios from its influence when the vehicles are removed and / or at the end the lowering of the barriers. These signals meet the standards in force and will have the power required to cover the distance required for the passage of the vehicle. Car radios interpret them as road signs and mute (radio / cd / gps) and / or dock on a defined HF channel to receive traffic clearance information. The RDS-TMC modulator sends all the codes in use so as to concern a maximum of receivers. Advantages :  No additional specific equipment for the motorist.  No specific installation except an electrical supply and a link with the tripping of the barriers and / or signals.  No necessary collaboration with broadcasters.
