Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for transmitting information to an unspecified number of drivers passing through a predetermined area, or to a number of fellow passengers, using a specific channel on a car radio or a radio transmitter, or a vehicle parked in a specific area. A loudspeaker system installed in the area is used to broadcast text to drivers and passengers of vehicles inside the area, and broadcast text regarding guidance, instructions, regulations, etc., such as traffic information, weather, terrestrial conditions, etc., is broadcast as road traffic information. The present invention relates to a road traffic information broadcasting system that automatically edits the syntax based on information from various sensors and transmits the syntax as broadcast audio.

Conventionally, this type of system has 1. A road administrator, person in charge of road regulation, etc., prepares the text to be broadcast, reads it out loud, and broadcasts it directly using a broadcasting device such as a transmitter or loudspeaker, or if repeated broadcasting is required. In such cases, it is recorded on tape and played repeatedly for broadcast.

However, in such a system, recommendations and instructions for road traffic are given from the perspective of road management.
Since most of the information that will be released in the future will not have a significant impact on traffic, it is necessary to keep false information to a minimum when broadcasting this information. Furthermore, once a broadcast is made, many vehicles will pass through the area, so even if a corrected broadcast is made, many vehicles will not be able to hear the broadcast.

In this case, it is necessary to create and broadcast a broadcast text based on the surrounding environment and future changes in the situation, but there are many types of broadcast texts that can be used for this, and in order to select one, It is necessary to take considerable experience and track record into consideration. In addition, even reports of simple situations that are too important are handled manually, which requires a large number of personnel, making the system extremely uneconomical.

On the other hand, broadcasting during emergency disasters such as buildings and factories,
In the case of station information broadcasts, etc., select from among multiple broadcast texts that have been syntaxed in advance for each sensor.
This was being broadcast. However, this broadcast text had the disadvantage that the text and audio content were not checked before broadcast, and corrections had to be issued after the broadcast if the content was inappropriate.

The present invention aims to eliminate these drawbacks and facilitate the transmission and operation of broadcast texts.

In other words, the broadcast text is displayed in text before it is sent out, and this is checked using an audio monitor to prevent the sending of false information, and the current broadcast text is displayed so that it can be checked, allowing for assembly and editing of the broadcast text. In order to streamline this process, input from various sensors placed at predetermined locations is processed to automatically assemble and edit text, and common texts such as situation broadcasts are sent out automatically, eliminating the need for specialist judgment. If a message such as a warning, instruction, or regulation or multiple suggestions are generated, the system displays the message, issues an alarm, and sends out the message after receiving confirmation from the person in charge.

Now, to be more specific, does it depend on the input information (weather, terrestrial conditions, traffic information, etc.)? Automatically or by the operator using a console and a broadcast text editing display device to compose the broadcast text, and after the syntax is completed, the broadcast text is created by the audio editing device using a control signal from the broadcast text editing control device. The audio is created and sent to a broadcasting device (transmitter, radio, public address system, etc.) via a transmission line.

Here, the audio editing device is a device that records audio information in advance in units of words and phrases and stores it in a storage element as is or encodes it, and sequentially outputs information from the storage element based on instructions from control signals. It is called and output as an audio broadcast text. In addition, if it is necessary to send broadcast text with different content to multiple areas at the same time, by specifying the output channel and the content of the channel, the content can be output to the channel and the different content can be sent at the same time. Use equipment that can output audio content to multiple output channels.

The details of the present invention will be explained below with reference to an embodiment shown in the drawings.

In Figure 1A, 1 is a weather sensor (for example, rainfall).

2 is a terrestrial sensor (e.g. cliff collapse, falling rock, avalanche, river water level); 3 is a traffic information sensor (e.g. total number of vehicles, vehicle speed, vehicle type); these sensors 1, 2.3 information is wired.

The information is input to the central broadcast text editing control device 5 via a wireless transmission line, organized by time and location if necessary, and displayed on the sensor input display board 4. In this case, the device 6 has data necessary for inputting text (not shown), and the operator inputs the information from the console 7 while looking at the broadcast text editing display device 6, and then broadcasts the text. It is now possible to assemble and edit sentences. The assembly and editing of this broadcast text will be described later. In this way, the edited text is confirmed by the characters displayed on the broadcast text editing display device 6, and if correct, the output channel number and broadcast audio control signal are sent to the audio editing device 9 to the designated area. . In this case, the audio editing device 9 has already sent out the designated broadcast audio to the transmission line during the above handling, and continues to do so during this operation. Further, when the audio editing device 9 receives the new control signal, it switches the changeover switch 11 of the output channel when the broadcast text that has been broadcasting on the output channel until now ends.
The sound source 13 is switched to the preliminary text sound source 13 using a tape, a player, or a semiconductor prepared in advance.
This information is configured to be sent to the transmission line side.

Therefore, there is no interruption of the broadcast from the terminal's transmitter 12. If interruption of broadcasting is permitted, the preliminary text sound source 13 is not required. On the other hand, the operator adds the output of the relevant channel of the audio editing device 9 to the audio monitor 1o, amplifies and monitors the broadcast content, confirms that it matches the content selected by the operator, and confirms that this is correct. In other words, if it is confirmed that the content is suitable for broadcasting under current conditions, the operation console 7
The message is sent to the broadcast message recording device 8, and the message 9 time is
After necessary information such as the broadcast area is recorded in text, the audio editing device 9 is connected to the transmission line side using the changeover switch 11, and the text is sent to the broadcasting device 12, which is a transmitter or loudspeaker. Then, the broadcast of new content will begin.

In addition, in FIG. 1A, sensor 1. Although the explanation has been made using one transmitter 12, in reality, if we take the sensor 1 as an example as shown in the figure, the number of transmitters 12 (12a-ci) is 1 a -1n, or the switch 11. 11a-11d depending on
Consisting of

Next, a method for assembling and editing sentences will be specifically explained.

Figures 2 and 3 are flowcharts for performing sentence syntax, in which Figure 2 is a fully manual system, Figure 3 is a system that automatically transmits broadcasts for predetermined items, and other systems. This embodiment has a complex operation function that enables automatic syntax for information that requires judgment.

First, fully manual text editing will be explained with reference to FIG. FIG. 4 shows a display example of the broadcast text editing display device 6 in the current display state in the figure, that is, in a standby state where no broadcast text editing operation is being performed. The road on which the broadcast will be broadcast is shown schematically at the top of the display, and the major place names, broadcast areas, etc. are easily displayed.

Furthermore, the part of the area broadcasting (in this example, Beishui CH-
2 rice, rice rice CH-4 rice ice) is displayed by linking, or in the case of color display, it is displayed in a different color from the others, and the CH number and broadcast message are displayed at the bottom.

This display state is a steady state in which the composition of the sentence has been completed and the broadcast is being made. Therefore, the next first operation starts with specifying the district, so it asks for the district number. In other words, approximately 2 "Broadcast C" is written at the bottom of the map.
H” is displayed.As shown in this example, a single number is given to multiple districts that have many opportunities to broadcast the same content (in this example, CH −
If CH-1 and CH-2 have the same content, enter the number 5 from the console 7). If it is necessary to change or cancel the broadcast content of a specific area that is currently being broadcast, select the appropriate number from among the area numbers specified on the display of the broadcast text editing display device 6 on the operation console. 7, the display changes as shown in FIG. 6 on the broadcast text editing control device 6. In this example, 1 is input to indicate the status of upstream broadcasting in A3 area.

This display displays the designated area, major headings, and operating instructions. For example, the special key [PE1], like an instruction, means stopping the broadcast or moving to the corresponding content. Wrong designation of broadcasting area 1. If you want to redo the designation of Jin, use the above-mentioned redo special key manually to return to the previous display state shown in Figure 4. In the case of manual broadcast cancellation key, the broadcast text recording device 8 prints out and records the - area, broadcast stop time, etc. using the broadcast text editing control signal, and records the broadcast audio of the audio editing device 9.
As shown in the figure, the status of the broadcast in the area where the broadcast was canceled is "Broadcast canceled" and the broadcast text is blank.If the input on the console 7 is a number, the designated area , small items and operating instructions are displayed. Small items are displayed in two formats: fixed sentences and additional sentences (-sentences with blank spaces). The conditions for canceling and restarting broadcasting are the same as in the major items above. One of the numbers displayed on the display is input and the display changes to ``East'' and the display in Figure 7 or Figure 8.

- Part 7 A shows an example of an additional sentence, and Figure 8 shows an example of a fixed sentence. In the case of additional sentences, items are displayed in each blank column, and the corresponding word or phrase to be inserted in the first blank column is given a number l and displayed in a list for the operator to select. When the operator inputs a corresponding number from the console 7 based on various information, the broadcast sentence editing control device 6 accepts this, and the blank space is filled in with the specified word or phrase. complete the sentence.

Next, the creation of the broadcast text for the A3 area up lane will be explained in more detail using FIG. The current situation is that we are preparing a message to announce a traffic stop due to falling rocks, and the blank spaces for the time are "am" and ".
8 o'clock" has already been filled in, and the next rockfall location has to be designated.

If the handler inputs 爲14, this sentence becomes ``A rockfall occurred near A3 Pass at 8:00 a.m.''.

After filling in the blanks in this manner, the display as shown in FIG. 8 will be obtained. At this stage, the operator confirms the broadcast area and content, and by typing a special key at step 7 during operation, for example, the [PEφ] key, - specified in the display in Figure 8,
Control signal to audio editing device 9-? y7, and as mentioned above, when the sentence being broadcast ends, the switching device 11 disconnects the connection with the broadcaster, and the audio monitor 10 picks up and confirms the completed broadcast sentence as audio information. If the broadcast text is appropriate, the broadcast text recording device 8 will record the broadcast text at 9 o'clock*1 in the broadcast area by inputting it from the console 7. Print out the broadcast.

Subsequently, the switching non-switch 11 is set to 1. The switch is switched to the audio editing device 9 side, and the audio output or audio information digital signal is sent to the broadcasting device 12 side via the transmission line.

As explained in 1 above, while editing the broadcast text, the previous content of the text is being broadcast from the broadcasting device 12'. While monitoring the new winter grass voice, use another sound source (preliminary text sound source 1).
From 3), the broadcast will continue with temporary provisional broadcast content (for example, "Currently changing to new information. Please drive safely. #").

Next, with reference to FIG. 3, handling during compound operation 7 will be explained.

In this case, the broadcast text editing display device 6 has a display as shown in FIG. The information obtained at this time, such as a warning regarding a catastrophe (heavy rain, heavy snow, 9 strong winds), etc., is input from the operator console 7 by the operator. When a change in state occurs in the master type sensors 1 to 3, the input information is taken into the broadcast text editing control device 6, the input information is processed, and as a result, the broadcast text editing display device 6 displays a display as shown in FIG. do. Although FIG. 9 shows a state in which three sets of proposed sentences are displayed, if only one created sentence were displayed, it would be possible to display the situation related to road traffic, such as weather or traffic volume.

If the content is a message that conveys the situation of traffic congestion, etc., record the broadcasting area, broadcast text and time of change, etc.
Automatically send out as audio information.

When a plurality of suggested sentences are displayed as in the example shown in FIG. 9, it is necessary for the operator to make a selection. In addition, road traffic regulations and requests for drivers must be broadcast with the consent of road administrators, road traffic control, etc.
(If a sentence or multiple sentences with content such as Confirm visually and audibly.If necessary, confirm together with the official in charge.If it is decided to broadcast after confirmation, use the special key for transmitting the broadcast from the console 7 manually to confirm the broadcasting area and time. , record the content, and start broadcasting.

We will explain in detail how to create sentences that are automatically broadcast and when to dismiss them. For example, human power emotions such as air and elephant are divided into the following ranks and evaluation values are assigned to each.

Table 1 is an example of the winter season, and different conditions and evaluation values are prepared for each region and season.

The sensor installed at ``12'' detected snowfall (evaluation value 1)', wind speed 6m/5ec (evaluation value 1), visibility 60m.
(evaluation value 1). The product of the evaluation values of the input information of these conditions is 1.

If the product of the evaluation values is 1, the program is programmed to enable automatic broadcasting. At this time, an example of a broadcast sentence is ``Around 12:00, the wind and snow were getting stronger and visibility was getting worse. Please drive carefully and maintain a safe speed and following distance. '. The wind speed becomes even stronger s m/
sea (evaluation value 2), it is necessary to instruct passing vehicles about driving conditions such as removal instructions. Therefore, it is necessary to confirm the above instructions from the operator. In this case, the product of the evaluation values is 2. Call the operator by emitting an alarm such as a buzzer. In this way, when the product of the evaluation values is 2 or more, it is possible to issue an alarm to call the operator and suggest a sentence. Also, if a strong wind and lightning warning is in effect, the evaluation value will be 3, and other input information will be ranked 1.
'', the person in charge of the broadcast must be called and checked by the person in charge before broadcasting.

An embodiment in which a plurality of suggested sentences are presented as shown in FIG. 9 will be described. For example, the road in the section from Tunnel 8 to A3 passes through a mountain range, and the evaluation values of the input information for this area are as shown in Table 2.

It is assumed that a heavy rain warning is being issued (evaluation value 3) and that the operator inputs information from the console 7 when the warning is issued.

(Such information can also be entered automatically by sending and receiving data.) A landslide sensor installed at point A4 was activated and generated the freshest information 1n (evaluation value 2). Assume that the amount of rain near a at this time was about 4 barrels per hour (evaluation value 1), and the daily rainfall amount after it started falling was 60 mm (evaluation value 2). In this case, the product of the evaluation ' values is 12, and automatic broadcasting is not possible. In addition, landslides, which are an important matter for road traffic, have started to occur (handled as a special item), and the rainfall amount for the 5th day during the heavy rain warning Sakura order is ranked 2.
”, (1) Current broadcast text (in this example, text 11) (2) Broadcast text regarding one-way traffic restriction (6-year-old text 12 in this example) (3) Broadcast text regarding road closure (in this example, text 12) The program is programmed to perform the sentence syntax in sentence 13).7 Furthermore, when one-way traffic9 is closed, vehicles still proceeding in the relevant section must be parked or turned around. It is necessary to set regulation sections by taking into consideration points where the road can be
It is known in advance. □In this example, the corresponding points on both sides near point A4 are other cars called A1 tunnel a11.

Suggested texts that meet these conditions are displayed on the broadcast text editing control device 6, and an alarm is issued. The operator uses information from various other sensors (weather, terrestrial, etc.), monitors from ITV cameras along the road, radio communications from patrol vehicles, and weather reports from telephones, radios, and pre-visit stations to determine the surrounding area. After assessing the situation, (1) If you think that the weather is expected to improve, -
Broadcast text 11 is selected and broadcast.

(2) If it is determined that the weather is not expected to improve and the landslides are likely to spread, one of the options listed in 12.13 of the broadcast text will be selected.

If (2) is selected, the broadcast text will be selected after consultation with related parties, including road regulation officials.

As mentioned above, what about things like landslides that have a huge impact on road traffic? In such cases, it is necessary to create a proposal for the current situation by combining hexagonal information, as well as create a proposal for when expansion is predicted, to alert users and prevent delays. In addition to landslides, special information such as avalanche detection and river water level warnings are processed in the same way. That's Central America.

As explained above, for drivers of vehicles traveling on roads,
Create broadcast text that conveys road information, combine various sensor input information with audio editing equipment, and broadcast without interrupting broadcasting.
Since the broadcast text can be edited and checked on the text and voice monitor before broadcast, it is possible to prevent the broadcast of incorrect information or instructions. In addition, the broadcast text is displayed on the road map, so by visually checking the map on the display,
It is possible to easily know the broadcast areas and their broadcast contents. While editing a text, the broadcasting district where the text is being created and the procedure for creating the text are instructed, and sensor input (weather, terrestrial phenomena, etc.) from a predetermined area is also provided.

If multiple sentences are automatically broadcast based on changes in traffic information (traffic information, etc.), or multiple sentences are generated from the sensor, this is created in a proposal format and an alert is issued, as well as displayed. It is a stone-cold device that calls the person in charge and selectively broadcasts the content of the proposal.

Therefore, it is used for traffic information broadcasting because it does not require a specific announcer for broadcasting and can quickly create correct information from sensor information and transmit it to vehicle drivers regardless of whether it is early in the morning, late at night, or on holidays. It has great social value.

In the embodiment shown in FIG. 1, the preliminary text sound source 13 is transmitted to the broadcast text editing control device 6. Although it is provided on the center side including the audio editing device 9, it may also be provided on the broadcasting machine 12 side including the switch 11 as shown in FIG.

In addition, when the preliminary text sound source 13 is provided on the broadcasting device 12 side,
Instead of switching when the broadcast syntax is updated, if the transmission line connecting to the center breaks down or the transmission level drops below a certain value, the switch f is switched to detect this and broadcast the information from the preliminary text sound source 13. , 11 is provided as shown in FIG.
-@, 3°, 9°4.2°. .

At least two broadcast information storage devices 121 and 122 are provided, and when the output of one storage device 121 is being broadcast, the other storage device 122 has a switching unit 111 consisting of a switch that can update the stored content. If ゜112 is set up, new information can always be broadcast. Furthermore, since broadcast information is recorded in the storage devices 121 and 122 even when updating is not required, there is no need to constantly send broadcast information from the center side.

Regardless of the broadcasting speed from the broadcasting device 12, the transmission speed of the broadcast content from the center to the broadcasting device 12 side can be freely selected. Furthermore, in such a case, as shown in FIG. 14, a switching device 131 is provided after the audio editing device 9, and the output side is switched when the broadcast area is specified using the operation console, so that the output of the audio editing device 9 is changed to 1CH. However, it is possible to transmit and store information by sequentially switching between areas, several areas, or several areas where it is not required to change different broadcast contents at the same time, as needed. The operating rate of the central audio editing device increases and it can be used more effectively. In addition, since the transmission line is not used all the time, it can also be used as a transmission line for remote monitoring of equipment by adding a selection circuit for other information, such as information on the operating status of terminal equipment by inserting a hybrid circuit, and information selection circuit for weather and other sensors. It can be used effectively.

There are road information sign boards along the road, but if the control signal for the road information sign board is also provided in advance when sending the broadcast signal from the center to the broadcaster 12 through the transmission line as shown in Figure 1, As shown in FIG. 13, the control unit can determine the information sent from the transmission line to the broadcasting device 12 side and control the display on the road information sign board 123, so that the display and the broadcast content can always be matched.

As described above, according to the present invention, it is possible to monitor and check the broadcast text before sending it out, so that it is possible to prevent the sending of erroneous information and to provide a road traffic information broadcasting system in which it is easy to assemble and edit the broadcast text. can be provided.
