Description

Intelligent road network system

Technical field

The utility model relates to a road marking, in particular to an intelligent road sign network system.

Background technique

A street sign is a sign that is fixed at a specific location for guiding, with instructions on the direction of the road and other relevant conditions. The purpose of our search for a street sign is mainly to know two questions: "Where am I,,, "Where to go,". 'The current common street sign is a directional road sign with the destination name and pointing to the destination direction. There are also electronic street signs, including LED text image electronic road signs and display electronic street signs. LED text image electronic road signs, such as bus station electronic road signs, can display the bus station name, travel information and other content. Display electronic road signs can be displayed A variety of information, such as the remaining parking space information in the front building, etc. The above existing street signs can only indicate the approximate location of the current location or destination location but cannot provide accurate location information, while the traditional street signs are mutually Independent, there is no relationship between them. Sometimes there is even confusion in the path finding through traditional street signs. The main reason is that traditional street signs indicate an area, such as "Houhai Street", standing on this road. ^ There is no way to confirm that it is Where is Houhai Street, so the existing street sign only answers the question "Where am I?" Half of the question, "Where to go," is also simply labeled "Left", "Right,", and then only half of the answer, can not completely solve these two problems. In recent years, the satellite signal positioning technology, which has been vigorously developed, has the characteristics of accurate positioning and global coverage, and can solve the problem of "Where am I" and "Where to go". However, in the city complex In the environment, satellite signal positioning often cannot quickly enter the working state. In addition, satellite signal positioning has accuracy problems. If there is a crossover drift, it may take 500 meters for the user to find the overpass. For example: When using satellite signal positioning, if the location is opposite the street and the actual environment cannot directly cross the road, , there will be a problem that the destination arrives at the actual but must travel a considerable distance to actually reach the destination. It can be seen that the above existing guiding technologies obviously have inconveniences and defects in use, and further improvement is urgently needed. How to create a new intelligent road sign network system that can be accurately and quickly positioned without being affected by weather, buildings and environment, and can clearly guide the road, is an important improvement target in the current field.

SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide an intelligent road sign network system that is free from weather, building, and environmental influences, can be accurately and quickly positioned, and can clearly guide the road, thereby overcoming existing road signs. And the lack of satellite signal positioning technology. In order to solve the above technical problem, the utility model relates to a smart road sign network system, which is mainly composed of a plurality of uniquely coded road signs, wherein each road sign comprises a main body and a road sign coding module fixed on the main body and an adjacent street sign pointing identifier. As an improvement of the utility model, the road sign coding module is one or a combination of a visual identifier, an identifiable identifier, and a wireless identification module. The visual identifier is a number, letter or text identifier. The identifiable identifier is a one-dimensional code identifier and/or a two-dimensional code identifier. The wireless identification module is one or more of an RFID module, a Bluetooth module, and a Wi-Fi module. The adjacent street sign pointing identifier includes an encoding, a direction, and a distance identifier of the adjacent street sign. The street sign encoding modules are all fixed on the visible area. The lower portion of the main body is further provided with a base. An LED backlight or a luminous sign is also fixed on the main body. With such a structure, the present invention has at least the following advantages:

1. Reduced positioning time, currently used satellite signal behavior, or auxiliary satellite signal positioning, no matter which positioning service's positioning time is longer, the first accurate positioning time of the satellite signal is about 1 minute, and the satellite signal positioning is assisted. The time is 12 seconds, and the wireless identification of the intelligent road sign network system of the utility model does not complete the positioning time for the user for more than 2 seconds;

2, improve the positioning accuracy, can be said to be zero error, satellite signal positioning accuracy usually has tens of meters or hundreds of meters of error, these errors may appear in the city and the actual position on either side of a building or on both sides of the road The user's location is very troublesome. The intelligent road sign network system of the utility model accurately identifies the physical location of the user, and the user finds the road sign and finds the exact location where he is located, especially for the precise positioning of the complex environment of the city. Demand

3, easy to use, the user can clearly know the direction and distance of the next street sign through the intelligent road network system, so that the destination can be easily found. For example, the tourist user in the old city of Suzhou can hold a map with the intelligent road network system. Find your destination easily along the smart street sign. In summary, the intelligent road sign network system of the utility model combines the visual identification, the identifiable identification, the wireless signal identification and the adjacent street sign pointing position identification, and naturally forms a smart street sign network due to the pointing relationship between adjacent road signs. Therefore, it can be free from the influence of weather, buildings and environment, accurately and quickly locate, and clearly guides the road, providing a new solution for urban traffic guidance. It is a useful supplement to satellite signal positioning technology, and has a public service field such as municipal construction. Significant, more suitable for widespread use.
