Description

Traffic sign {Traffic signboard}

The present invention relates to a traffic sign that can display driving-related information, such as a time required for driving to a specific location, more specifically.

Many conventional road signs are provided with a plurality of traffic signs, and the traffic signs usually display the remaining distance to the area to come out. However, what drivers want to know while driving is how much time they will take to reach a particular destination rather than the remaining distance, and whether they will be exposed to conditions that hinder driving such as snow, rain, and fog. Signs are difficult to meet the needs of these drivers.

On the other hand, in order to overcome such a problem in recent years, a number of road traffic information signboard in the form of a signboard has been installed. These billboards are installed on one side of the road or in the middle of the road, and in case of driving in the usual way, the driver informs the driver of the time required to reach a specific position or the accident, delay and congestion of a certain section.

The operation method of these road traffic guide billboard is as follows. First, a local government or a traffic related institution installs a signboard at a specific place on the road, and then connects the installed signboard with a specific traffic information center through wired / wireless communication means. Subsequently, the traffic information center collects various road traffic information and then transmits necessary data for each electric sign. For example, the signboard installed at the southern end of Banpo Bridge in Olympic Boulevard notifies the traffic conditions at the Olympic Boulevard and the riverside north road, and the signboard installed at the south end of Hannam Bridge is notified of traffic conditions in major sections of Gyeongbu Expressway.

To this end, the traffic information center should collect numerous traffic information of the whole country or a specific region, classify the necessary data by each billboard, and provide the classified data to each billboard. This procedure is very complicated. Not only does it take a lot of time and money. In addition, when the traffic information center is stopped due to a specific accident, etc., there is a disadvantage that the operation of all the electronic signs covered by the traffic information center is also stopped. In addition, the display board is not only a very expensive equipment, but also a wired and wireless communication means for transmitting and receiving data to and from the traffic information center is very costly for this, and in the case of a wired communication means, even in the case of failure due to disconnection It has the disadvantage of being vulnerable.

Therefore, an object of the present invention is to solve the problem that it is not possible to provide the traffic information changing in real time of the conventional traffic signs.

In addition, an object of the present invention is to solve the problem that the conventional road traffic information billboard has a high cost, and difficult to operate and maintain.

Therefore, an object of the present invention is to provide a traffic sign that can provide traffic information that changes in real time in order to solve this problem.

Traffic signs according to the present invention for achieving the above object is:

Board;

A display device formed on a portion of the substrate surface; And

In this case, the data provided to the display device preferably further includes alarm situation data.

According to the present invention, by installing a road traffic controller and display device using the DMB in the existing traffic signs, instead of simply guiding the distance to a specific specific destination, it takes both the time required to arrive and the danger signal of a specific section. Can provide.

In addition, since it is not necessary to establish a communication line and a power line as compared to the existing road traffic information billboard, it is possible to obtain a similar effect to the existing road traffic information billboard.

A traffic sign according to a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is a view schematically showing the configuration of a traffic sign according to a preferred embodiment of the present invention.

As shown in FIG. 1, the traffic sign includes a substrate 10, a display device 20 formed on a portion of the substrate surface, a controller 30 for providing predetermined data to the display device, and an external DMB signal. DMB antenna 40 and the photovoltaic device 50 is included.

Specifically, the substrate 10 is not limited to the type as long as it is used for a conventional traffic sign. In addition, basic information such as a specific destination and road information is printed on a part of the substrate 10, and in particular, the display apparatus 20 is further installed.

In addition, the display device 20 is not limited as long as it is a device capable of displaying the data on the screen when predetermined data such as numbers, letters, and symbols are provided through the controller 30.

2 is a block diagram schematically illustrating an internal configuration of a controller according to a preferred embodiment of the present invention. First, the controller 30 includes a data receiver 31 for receiving external DMB data relayed through the DMB antenna 40, a decoder 32 for decoding external DMB data received by the data receiver; And a calculation unit 33 for calculating the decoded data in a predetermined manner, a data transmission unit 34 for transmitting the calculated data to a display device, and a control unit 35 for controlling various functions of the controller. do.

In addition, the DMB antenna 40 receives the DMB signal transmitted from the transmission station, and provides it to the data receiver of the controller 30. The DMB antenna 40 is sufficient to use a commonly used product and does not limit its type.

In addition, the photovoltaic device 50 functions as a power source of a traffic sign according to a preferred embodiment of the present invention. That is, the photovoltaic device 50 functions as a power supply source required for the operation of the display device 20 and the controller 30 of the traffic sign. The photovoltaic device 50 is sufficient to use a commonly used product and does not limit its kind. The present invention can provide a traffic sign capable of guiding the arrival time to a specific section at a low cost because it does not need to include all the power lines and communication lines that are essentially installed in the existing road traffic guide billboard.

The operation principle of the traffic sign having the above configuration will be described below with reference to FIG. 3. 3 is a diagram schematically illustrating a procedure for guiding traffic using a traffic sign according to the present embodiment.

As shown in Fig. 3, the CMS server forms basic data for traffic information for providing traffic and travel information, and provides the basic data to a DMB broadcasting station. Meanwhile, the CMS (Contents Managemnet Server) server may be directly operated by an institution that collects road traffic information such as Korea Expressway Corporation, or may be operated as an independent server that collects data and processes the data. It may be.

Subsequently, the DMB broadcasting station forms traffic and travel information (TTI) data based on the basic data, and then provides the same to a traffic sign according to the present invention through a transmission station. In this case, the TTI data formed by the DMB broadcasting station is preferably TTI data using a TPEG (Transport Protocol Expert Group) structure. In addition, the DMB broadcast station is preferably a terrestrial DMB broadcast station. In particular, according to a preferred embodiment of the present invention, the traffic and travel information data preferably includes driving time data for each predetermined section on the road.

An example of a method of providing driving time for each section in the traffic and travel information data is as follows. First, each domestic road is divided appropriately. For example, in the case of Gyeongbu Expressway, several roads across the country are divided by sections, such as Hannam IC, Banpo IC, Banpo IC, Yangjae IC, .... Cheonan IC, Cheongju IC, Cheongju IC, Mokcheon IC ... , A unique link ID is assigned to each section. For example, the link ID is 2000001001 between Banpo IC station in Hannam IC, 2000001002 in Yangjae IC section in Banpo IC, 2000001002 in Cheongju IC section in 2000, and 2000001010 in Cheongju IC section in Cheonan IC, and 2000001020 in Cheongju IC in 2000001020. ID can be assigned in various ways that do not overlap. Subsequently, an institution that collects road traffic information such as Korea Expressway Corporation measures real-time driving time for each section, and requires real-time driving for each section by matching each ID with the time required. Time can be measured. Subsequently, the real-time driving time data for each section measured by the method is transmitted to the DMB broadcasting station through the CMS server, and the DMB broadcasting station converts the data into TTI data and transmits it to the traffic sign through the transmitting station.

On the other hand, the data transmitted to the DMB broadcasting station through the CMS server is other data in addition to the real-time driving time data, for example, accident information of the relevant section, weather-related information such as fog / rain / snow / hail, construction related information It further includes various related data, and therefore, the data is preferably processed into TTI data along with real time driving time data and transmitted to the traffic sign.

Subsequently, the DMB signal (TTI data) transmitted to the outside via the transmitting station is provided to the data receiving unit 31 through the DMB antenna 40. Therefore, the external DMB data provided by the data receiver 31 is preferably TTI data, more specifically TPEG data. In addition, the data preferably includes a road state component of the TPEG RTM standard and a link ID component of the TPEG LOC.

Subsequently, the decoding unit 32 decodes the TTI data, more specifically DMB data, which is TPEG data, and extracts driving time data for each section.

Subsequently, the calculation unit 33 extracts data for a required section from the driving time data for each section. For example, a traffic sign mounted on a road traffic sign installed at Cheonan IC among the Gyeongbu Expressways to guide the driving time from Cheonan IC to Cheongju and Busan, first, will be operated by using Gyeongbu Expressway from Cheonan to Cheongju and Cheonan to Busan. In this case, the section to be routed is extracted. For example, if there are four sections required to reach Cheonan from Cheongju, and the link ID of each section is 2000001010, 2000001020, 2000001030, 2000001040, the four link IDs are extracted and the driving time information for each ID is checked. Since link IDs are assigned and managed by a country for many road sections in the country, these link IDs may be used as they are, or link IDs of a separately required section may be assigned and used.

Subsequently, if the total driving time of the four IDs is 20 minutes, the driving time from Cheonan to Cheongju is determined to be 20 minutes. Similarly, if there are 30 link IDs required to reach Cheonan from Busan, the 30 IDs can be extracted, and the required time information for each ID can be checked and summed to determine the driving time from Cheonan to Busan. have.

That is, the traffic sign according to the present embodiment is focused on the fact that only the time required for driving for several sections from the point where the sign is formed to the point to be guided. Therefore, only the information on a specific link ID among the many TPEG data received through the DMB antenna is decoded, and simply calculating the driving time from a specific point to another point simply by adding up the decoded time information. will be.

For example, in the case of searching for a route and time required using a conventional navigation terminal, a GPS receiver for identifying a current position must be provided since it is necessary to search for a route and time required from a current position of a mobile terminal to a specific point. If there are various paths from the current position to a specific point, a complicated calculation process is needed to find the optimal path. On the other hand, according to the present embodiment, since the position where the traffic sign is installed is fixed, no GPS terminal is required, and one can be specified as a route to a specific point, so that no additional calculation for searching for a route is required.

On the other hand, those skilled in the art to which the present invention belongs to decode all the DMB data provided by the decoding unit 32, the operation unit 33 extracts only the link ID that needs to be calculated and the required time of the link ID It will be appreciated that the decoding unit 32 may initially decode only the link ID for which the operation is necessary and extract the required time.

Subsequently, the data transmitter 34 transmits driving time data for the specific point calculated above to the display device 20 for displaying the driving time of the corresponding point, and the display device displays the received time data. Mark on.

On the other hand, the traffic sign according to another embodiment of the present invention, in addition to the display of the required time data, and other various data related to the safe driving, such as accident information of the corresponding section, weather related information such as fog / rain / snow / hail, construction related information I can display it. That is, the DMB data transmitted to the data receiver 31 may further include accident information on a specific link ID (section), weather related information such as fog / rain / snow / hail, construction related information. Therefore, if the decoding unit 32 also decodes such accident information or weather related information, the data transmitter may transmit the information to the display apparatus 20 through the data transmitter 34. Alternatively, the required time information and other information such as weather may be delivered at regular time intervals. For example, when the fog is severe in the Cheonan-Cheongju section, the display device may alternately display various information such as fog display, driving time, and remaining distance at regular time intervals.

4 is a diagram illustrating an example in which a traffic display panel is driven according to a preferred embodiment of the present invention. First, as shown in Figure 4 (a), the time required from the traffic signs installed in Cheonan IC to Busan and Cheongju in real time simply by installing a small display device, such as LED window on the street display portion of the existing traffic signs I can display it. 4 (b) and 4 (c) are modified forms of FIG. 4 (a). For example, when the fog is severe in the Cheonan-Cheongju section, “Fog” is displayed in Korean or the fog mark is displayed. Can be ventilated.

The configuration of the traffic sign and its operation method according to the present invention has been described with reference to the preferred embodiment. However, one of ordinary skill in the art will recognize that various modifications and variations can be made to the embodiment. Therefore, the scope of the present invention is limited only by the utility model registration claims to be described later.
