Method and system for managing real-time state of indoor map passing road section

Abstract

The invention discloses a method and system for managing the real-time state of a passing road section of an indoor map, and the method comprises the steps: dividing all channels in a parking lot into a plurality of continuous road sections according to 5-7 meters, marking the road sections and intersections respectively, planning a preset route for entering or leaving vehicles according to the channels and parking spaces in the parking lot, acquiring a road section sequence and an intersection sequence of a preset route; determining an impassable section and an unavailable parking space, specifically, presetting a monitoring duration T and a fault threshold value; acquiring a real-time route of the vehicle, generating a to-be-confirmed section, judging whether the to-be-confirmed section is an initial fault section or not, accurately searching an impassable section from the initial fault section, and avoiding the impassable section and an unavailable parking space when a preset route is planned. The system can timely and effectively monitor the impassable sections in the parking lot, timely and effective path planning is carried out on the vehicles in the parking lot, the response speed is high, the time is short, and the system is especially suitable for indoor parking lots with large traffic flow and complex roads.

Description

technical field [0001] The invention relates to a road section management method and system, in particular to a method and system for managing the real-time state of an indoor map passable road section. Background technique [0002] At present, when navigating indoors, the navigation system often plans a preset route for the entering or leaving vehicle based on the collected information. Plan the route from the parking space to the exit. At present, planning methods in this area have emerged, which can match the optimal route according to the specific location of the parking space. [0003] However, indoor navigation is different from outdoor route navigation, especially in some parking lots, with large traffic flow and complex shape of the parking lot, which require extremely high real-time status of each road section. Currently, the known navigation systems on the market are updating the channel information in time. There are certain requirements and delays. For example,...

[0003] However, indoor navigation is different from outdoor route navigation, especially in some parking lots, where the traffic volume is large and the shape of the parking lot is complex, and the real-time status of each road section is extremely demanding. Currently, the known navigation systems on the market update channel information in a timely manner. It has certain requirements and delays. For example, multiple people are required to manually report congestion information, or there is a delay of several minutes in actively obtaining congestion information, which does not meet the real-time requirements of indoor navigation.

If a section of the indoor parking lot is unavailable due to various reasons such as traffic jams, accidents, or construction, it cannot be fed back to the indoor navigation system in time, resulting in inaccurate navigation information and unavailable navigation planning routes. It is inconvenient, when the traffic flow is heavy, it will also increase the congestion of other road sections
