Guide label-based regional traffic directing server

Abstract

The invention discloses a guide label-based regional traffic directing server which is characterized by comparing a data storage unit (1), a line planning unit (2), a guide directing unit (3), a management maintaining unit (4) and a communication interface unit (5). The server is used for building a guide network according to stored geographic information data and information such as a key position, a guide position, a usable route and the like; and ensuring a destination and the current guide position after a guide directing request is received, ensuring an optimal line from the current guide position to the destination based on the guide network by adopting a line planning algorithm, generating integrated guide direction, and feeding the integrated guide direction back to a guide terminal. By adopting the management maintaining unit, the server is used for offering a maintenance method to geographic information data, the guide network and link cost weight, so that the optimal line can be dynamically adjusted by a manager according to the condition of the regional traffic.

Description

technical field [0001] The invention relates to the field of traffic guidance, in particular to an area traffic guidance server based on guidance tags. Background technique [0002] Traffic guidance is a necessary service for people in production and daily life. [0003] The traditional personal traffic guidance method includes the following steps: [0004] (1) Select the destination; [0005] (2) Determine the current location; [0006] (3) Mark the starting point and destination point on the map; [0007] (4) Plan the optimal route according to the map; [0008] (5) Convert the optimal route into traffic guidance for the actual environment, including: go ahead 100 meters, turn left, turn right, etc. [0009] In addition, the demand for regional traffic guidance services includes: [0010] (6) Traffic guidance can reflect changes in geographic information in real time: such as route diversions, location changes, etc.; [0011] (7) Traffic guidance can dynamically ada...

AI Technical Summary

Problems solved by technology

[0013] (1) Signal strength limitation: GPS signal strength is affected by weather and buildings, especially in indoor and underground buildings where the GPS signal is weak;

[0014] (2) Navigation range limitation: GPS is more suitable for plane range navigation, but for internal navigation of multi-storey buildings, GPS sometimes indicates errors; and it is difficult to provide navigation such as "10 floors up the elevator" and "5 floors down the elevator";

[0015] (3) Navigation accuracy limitation: The signal accuracy of commercial GPS is limited, and it is difficult to navigate to specific portals, shops, counters and office card positions in dense commercial office areas;

[0016] (4) Equipment cost limitation: The built-in commercial GSP signal receiver in the terminal leads to an increase in the cost of terminal equipment;

[0017] (5) Restrictions on real-time update: Geographical information data is stored inside the terminal, which has a lag effect in updating;

[0018] (6) Dynamic adaptation limitation: When traffic congestion occurs on some lines in the region, managers lack the means to dynamically adjust the optimal line;

[0023] (3) High label cost: RFID readable and writable labels are required, and the cost is usually higher than that of barcode labels, QR code labels, and read-only labels, and there is cost pressure in high-density deployment;

[0024] (4) High terminal configuration: The terminal not only needs to save geographic information data, but also execute route planning, which requires strong computing power and storage capacity;

[0025] (5) Geographic information update is slow: the terminal saves geographic information data, and its update has a lag effect, and the latest geographic information changes are difficult to reach all terminals in real time;

[0026] (6) Lack of dynamic adaptability: when some lines in the area are congested, managers lack the means to dynamically adjust the optimal line;

[0027] (7) It is cumbersome to use: the user can only identify hop by hop and confirm the recognition operation one by one; only the information of the next hop label can be obtained each time, and the complete traffic guidance information cannot be returned at one time
