Abstract

The present invention is installed in the tunnel exit, using the underground operating broadcasting equipment (10) that is already in operation or to be installed in order to prevent vehicle traffic accidents in the event of deterioration of the road weather that is concentrated in the tunnel or the exit in the highway and national road section. Road Weather Information System (1

The present invention relates to a system for preventing vehicle accidents such as skids and collisions caused by sudden braking of vehicles immediately before the exit by transmitting the exit road information transmitted in real time to the tunnel users from time to time.

The number of tunnels in the road continues to increase due to the nature of many mountainous areas, and it is impossible to transmit radio waves inside the tunnel due to spatial problems that are blocked from the outside, and to prevent the inconvenience of radio reception by road users. (10) is used to relay the radio. In addition, the equipment is equipped with an emergency broadcasting equipment 26 to perform emergency broadcasting at the discretion of the worker in a traffic accident inside a tunnel, vehicle fire or weather worsening at the exit. In general, due to the nature of tunnels in the high and mountainous regions, general weather information is often inconsistent with the site, and the change is arbitrary, which makes it difficult for the workers to cope with the situation, and also occurs when the emergency broadcasting is continuously carried out throughout the tunnel. It is a reality that emergency broadcasting itself is reluctant due to inconvenience of receiving radio broadcasting and complaints.

The present invention receives the road weather information system 150 installed in the tunnel exit unit and individual road information signals (rainfall, snowfall, fog, etc.) transmitted from the underground broadcast equipment 10 or the line amplifier (30). The wireless speaker 50 is a configuration of a system that prevents vehicle accidents by delivering weather conditions at the exit to the road users in real time, and is limited to only about 3 to 500M sections of the tunnel exit, which can be recognized by the vehicle driver. It is characterized by including all the radio wave and voice signals of the frequency band.

Description

Tunnel rebroadcasting controll system for protecting traffic accidents at tunnel exit, by using Road weather information system}

The present invention is to prevent traffic accidents in the tunnel exit by using the road weather information system 150 installed in the tunnel exit, emergency broadcast transmission using the radio and wired and wireless speakers only in the exit section, not the entire tunnel. It relates to a possible underground broadcasting equipment 10 operating system.

The existing underground tunnel broadcasting equipment (10) currently used is generally not limited to use the audio output of the radio and speakers to a certain section, and the built-in emergency broadcasting device is a text embedded in a CD or tape or memory. Under the judgment of the tunnel manager, it is constructed to operate the tunnel up and down selectively through manual operation of the worker in the event of fire or accident in the tunnel and bad weather at the exit of the tunnel. Occasional change of workers due to occasional change and interruption of radio users' listening to radio broadcasting when sending out the whole section of the tunnel causes complaints, which restricts the operation of the appropriate underground broadcasting equipment 10 with the safety of road users in mind. There is no choice but to have.

Accordingly, the object of the present invention is to receive the weather information from the road weather information system 150 installed in the tunnel exit section underground material broadcasting equipment that can periodically send the announcements intensively only 3 ~ 500M section just before the tunnel exit (10) By constructing the operating system, it is intended to prevent a vehicle accident at the exit of the tunnel and a subsequent internal vehicle accident.

As a means to solve the above-mentioned problems, considering the tunnel to be opened and newly opened and the newly opened tunnel, the length and topographic characteristics of the tunnel section are determined, and the application method is changed to apply the above-mentioned tunnel. The road weather information system 150 and the underground ash broadcasting equipment 10 select equipment that meets the purpose of the existing products developed.

When the underground broadcasting system 10 operating system according to the present invention is used, road users who forget the external weather situation during long time operation inside the tunnel during rainfall and snowfall or do not recognize the change in the external weather when entering the tunnel are immediately before the exit part. By visually confirming the external weather conditions at the outside, it is possible to prevent sudden braking that is performed just before the exit or limit the section to the inside of the tunnel so as to prevent traffic accidents due to rain or snow slipping or fog. .

Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1 is a schematic configuration diagram of a system and an implementation device to be implemented by the present invention. In general, a system block diagram of the underground broadcasting equipment 10 installed and operated in a tunnel is connected to the radio and the radio in the tunnel. Fig. 12 shows the layout and equipment configuration of a leaky coaxial cable 35 for transmitting a wireless speaker. The road tunnel section installed in the mountain area or underground section is a structure that is hard to receive radio transmission signal from the outside, and to force the FM / AM signal into the tunnel by using the underground broadcasting equipment 10 to prevent inconvenience of road users. It is. After receiving each radio signal from the AM / FM antenna 20 installed in the tunnel management building or near the tunnel, and separating the FM and AM signals through the AM / FM signal separator 21, the FM signal separates the FM signal repeater 22. After retransmitted by transmitting the attenuated transmission signal through the FM signal splitter 24 to separate and send the FM signal up and down. After amplifying the signal through the amplifier 28, and then transmits the radio wave through the FM transmission leaky coaxial cable (35). After a certain period in accordance with the extension of the tunnel by installing a line amplifier 30 to re-amplify the signal An anti-reflective termination resistor (60) is provided at the end to prevent radio waves from being resent (retroreflected) inside.

The AM signal reproduces and retransmits the attenuated transmission signal through the AM signal repeater 23, and then separates and transmits the AM signal up and down through the AM signal distributor 25. Generally, the AM signal does not use a separate amplifier, and like the FM signal, an anti-reflective terminal resistor 60 is installed at the end to prevent the radio waves from being resent (reversely reflected). In addition, the wired / wireless speaker 50 is a speaker used to propagate a situation in an emergency situation in a tunnel. In the past, a voice transmission line was installed to directly transmit a voice. It is also using a method of transmitting a signal to a representative speaker by group or by controlling it in parallel for each zone. When the vehicle is running inside the tunnel, it is difficult for road users to fully recognize the speaker's voice due to the noise caused by the howling phenomenon that occurs in the structure. However, the traffic accident prevention effect according to the present invention may be insignificant. The facilities are collectively configured in the underground ash broadcasting facility 10 and can give a sense of alertness to the road users who are not listening to the radio broadcasting during the tunnel section operation.

The road exit information system 150 is installed at the tunnel exit part to detect signals including rainfall, snowfall, road frost, fog, etc., which are specific weather conditions near the exit part, and then the road weather information system 150 detects a signal. According to the input signal, the controller directly transmits a radio signal to the line amplifier 35 or the wired / wireless speaker 50, or transmits an audio signal to perform an emergency broadcast or according to an input signal. By controlling the emergency broadcasting equipment 26 embedded in the underground ash broadcasting equipment 10 installed in the to transmit the stored voice through the AM / FM radio or to operate the wired and wireless speakers. If there is a distance or technical limitation in the method using the existing underground ash broadcasting equipment 10, only the 3 ~ 500M section, which is the corresponding section, is installed separately from the road weather information system 150 by installing the exit underground broadcasting equipment 15 separately. The above operation is realized by controlling the exit underground re-broadcasting equipment 15 through the transmitted signal through the controller 200.

2 is the controller 200 after the controller 200 receives the weather information received from the road weather information system 150 and temporarily restricts the operation of the line amplifier 30 that amplifies and sends the output to a corresponding section in the tunnel. It is an exemplary diagram of a system for transmitting an emergency broadcast voice text stored in the line amplifier 30 or a voice text directly to the wired / wireless speaker 50.

3 shows that the controller 200 receives weather information received from the road weather information system 150.

When the control signal is transmitted to the emergency broadcasting equipment (26) in the underground broadcasting equipment (10) by the corresponding road information signal in the serial communication method (RS-232 / RS-422 / RS-485 etc.) or optical communication method, the emergency broadcasting is performed. Exemplary diagram of a system in which the equipment 26 can directly perform emergency broadcasting directly through the corresponding line amplifier 30 or the wired / wireless speaker 50. At this time, in the case of AM radio broadcasting, a separate AM radio line amplifier 30 is installed in a corresponding section as in FM radio broadcasting or the FM radio line amplifier 30 is controlled to transmit.

FIG. 4 illustrates a case in which the system and the controller 200 are difficult to install due to a functional problem of the previously constructed underground broadcasting equipment 10 or a restriction on the distance between the entrance and exit of the tunnel. Install a separate outlet underground broadcasting equipment 15 only and transmit the weather information received from the road weather information system 150 to the controller 200, and then the controller 200 directly exits the underground broadcasting equipment 15 or The same effect can be expected by controlling the built-in emergency broadcasting equipment.
