Description

A real-time interactive navigation system and method for setting an area

technical field

The invention relates to navigation technology, in particular to a real-time interactive navigation system and method for setting areas.

Background technique

The navigation system is based on satellite positioning system and electronic map technology to design walking routes for users and provide navigation systems in real time. The realization of navigation mainly depends on the powerful electronic map technology. The navigation system can automatically plan corresponding navigation routes according to the starting point and destination input by the user. These planning routes can be set whether to pass through certain way points, and whether to avoid expressways, etc. When the user does not follow the planned route or takes the wrong route, the navigation system will re-plan a new route to the destination based on the user's current location.

It should be noted that the existing navigation system relies on the set navigation algorithm and road information in the electronic map to achieve route navigation, and currently has the following defects:

Whether the existing navigation system is based on a preset route or a navigation route calculated according to a certain algorithm, each time the navigation system is required to plan a route, within a period of time, as long as the input starting point and end point of the navigation remain unchanged, The determined navigation route result is always the same. In this case, if the user finds that the navigation result is inaccurate or unreasonable, he cannot obtain a more accurate result by sending the navigation request again.

The existing navigation system cannot well meet the navigation needs of hotspot parks. Taking popular scenic spots such as the Summer Palace and the Forbidden City as an example, the system should plan the tour route according to the importance and congestion level of each scenic spot in the scenic spot. However, the situation of the Forbidden City and the Summer Palace are different, and the rules of the route need to be adjusted, that is to say, it needs to be reset. Adjust the data input of the automatic navigation computing system, and this change has obvious randomness, which increases the implementation risk of the navigation system and the cost of system deployment. In addition, when the map data is not updated, the existing navigation system cannot find road interruptions or new passages caused by temporary construction in the hotspot park, and the calculation based on the existing data will not be able to obtain appropriate results that are actually available. When the destination point set by the user is an unknown point of interest (blind spot) in the map database of the navigation system, the navigation system will not be able to complete the navigation request.

To sum up, this type of navigation system is not suitable for scenarios with a large range and high accuracy requirements for location applications.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

The real-time interactive navigation method for setting an area of the present invention is applied to a system with a navigation service center, user equipment and a communication network; wherein, the navigation service center is located on the network side, is the entity where the navigation processing logic resides, and can be provided by the navigation service Users of the center consume and process navigation requests sent by user devices. In the present invention, the navigation service center is located in a hotspot park where the basic communication network has been deployed, such as a tourist attraction area, such as a park; of course, it can also be set in some communities or blocks such as commercial streets or pedestrian streets. The user equipment is generally a mobile intelligent terminal such as a mobile phone, and generally has a positioning function such as a global positioning system (GPS, Global Positioning System). The mobile intelligent terminal of the present invention is not limited to the GPS positioning function, and can also support a satellite-based augmentation system (SBAS, Satellite Based Augmentation System), Quasi Zenith Satellite System (QZSS, Quasi Zenith Satellite System) and Galileo (Galileo) system and other positioning functions, but are not limited to the above technologies. The mobile intelligent terminal mentioned above has basic communication capabilities, such as being able to communicate with a positioning service center through a basic communication network. The basic communication network here includes a telecommunication network, a mobile network, etc. or a combination thereof.

The navigation service center of the present invention is mainly used for performing navigation calculation on the positioning target address requested by the user, so as to provide navigation routes. The navigation service center includes a database for storing electronic map information of the set area, a navigation route determination center, and a communication unit for communicating with the user equipment and the basic communication network, which is used to periodically The update unit for updating the electronic map information of the hotspot park in the database; the electronic map information of the set area is stored in the database, and the electronic map information needs to be periodically updated according to the real-time road condition information of the hotspot park, such as when some road construction and other information. The electronic map information of the present invention also includes related information of related locations, such as parking lot and current parking space information, etc., and the related information of these locations needs to be constantly updated. Information about the location will be described in detail below.

The greatest feature of the present invention is that it can provide more detailed navigation routes of hotspot parks, and the relevant location information in the electronic map of hotspot parks is divided very finely, such as toilets, buildings, shops, supermarkets, banks that cannot be provided in ordinary electronic map information , post offices, telephone booths, newspaper kiosks, restaurants, parking lots, scenic spot landmark buildings, scenic spot landmark area information, etc., can all be provided by the present invention. This is fundamentally different from the way of providing route information in general electronic maps. The present invention uses these location information to calibrate the navigation route, thereby providing the user of the user device with a better travel route, and at the same time, providing the relevant information of the relevant location to the user device user, so that they can fully understand the scenic spot settings of the hot spot park And basic equipment supporting information, etc., so that user equipment users can better understand the hotspot park.

The electronic map information of the present invention will be updated in real time according to the actual situation of each location, so that the user equipment user can know the location-related information of the hotspot park in real time and provide better navigation routes. When some lines have construction or traffic characteristics in different time periods, the navigation service center of the present invention will update the relevant information into the electronic map information, and when navigating according to the user's navigation request, will combine these position information to update the navigation line. Perform calculations to avoid providing users with impassable or inaccessible routes. The navigation route provided by the invention is more accurate and reasonable. In the present invention, the electronic map information maintained by the navigation service center is set based on the hot spot park. Specifically, on the basis of the third-party electronic map information, information about the relevant scenic spots in the hot spot park can be added in the area corresponding to the hot spot park. , attractions introduction information, information about infrastructure conditions, such as attractions, restrooms, newsstands, shops, restaurants, sidewalks and other relevant information in the hotspot park are added to the hotspot park on the third-party map. In addition, The electronic map information of the present invention also stores relevant information of the above-mentioned relevant positions, such as introduction information of scenic spots, business information of stores, parking conditions of parking lots such as how many parking spaces, whether there are currently parking spaces and other information. When the user passes through these scenic spots, the above-mentioned relevant information is displayed to the user.

The electronic map information of the present invention can also be specially designed electronic map information, that is, the maintainer of the navigation service center sets up a dedicated electronic map of the corresponding hotspot park according to its own demand for the electronic map. When the user communicates with the navigation service center through his own user equipment, the dedicated electronic map information is downloaded to the user's user equipment. Or, as an implementation means, the user of the user equipment actively downloads the information into his own user equipment. For example, the navigation service center provides electronic map information on relevant websites, and interested users can download the electronic map information.

In the present invention, the navigation route determination center mainly generates the corresponding navigation route according to the user's navigation request. Since the present invention provides navigation service in a specific area, the granularity of navigation will be finer. When receiving a navigation request from a user requesting a restroom, according to the current position information of the user, the relevant information of the restroom will be searched in the electronic map information of the hotspot park of the present invention, and the relevant route data found will be sent to the user of the user equipment. In the present invention, the destination requested by the user for navigation may be a place not entered in the electronic map information. The location coordinates of the electronic map information are not entered, so as to generate the corresponding navigation route and feed back to the user device user. Of course, when it is determined that there are roads under construction or restricted (such as too many tourists) in the navigation route generated for the user, a new navigation route will be re-determined for the user and fed back to the user. The navigation service provided by the navigation service center of the present invention truly realizes interaction with users. For example, instant communication with the navigation service center is realized through the instant message on the user equipment, and a navigation request that can meet the needs of the user is generated. Alternatively, the relevant navigation request is sent to the navigation service center through the short message mode of the user equipment, and the interaction between the two parties can be realized by receiving the short message from the navigation service center. Of course, the user can also communicate with the staff of the navigation service center through the voice function on the user device to express the navigation request, and the staff of the navigation service center inputs the navigation request required by the user to the navigation service center to realize corresponding navigation. The voice mode in the present invention is a voice service added in the navigation interface, that is, when the user equipment is in the navigation interface, the user can realize the call to the navigation service center through the icon of the voice mode, and realize the voice communication with the navigation service center. Communication, so that the user can communicate with the navigation service center without exiting the navigation interface. Those skilled in the art should understand that it is easy to realize the voice service through the navigation interface, such as realizing the above functions through the IP-based voice service.

Those skilled in the art should understand that the navigation calculation based on the target location information and the user's current location information is an existing technology, and the navigation calculation is not the key point of the technical solution of the present invention. detail. The navigation calculation in the present invention needs to fully consider the road traffic conditions in the electronic map information. When it is determined that the current road construction or road congestion is caused by too many tourists, other smooth route information is provided to the user device user, such as some routes that are not recognized. Convenient road routes known to most people, etc. In a word, the present invention can provide users with navigation routes suitable for hot spots, and provide users with better hot spot navigation services.

In the present invention, information related to location information can also be provided, such as whether the road is under construction, whether the road is allowed to pass, the current parking situation of the parking lot, the current business information of the supermarket, and the current customer flow information of banks and post offices. These information are updated together as electronic map information, and the update period can be set according to actual system requirements, such as half an hour, 1 hour or 20 minutes.

The essence of the technical solution of the present invention will be further explained in detail below in combination with the flow chart.

Fig. 1 is a flowchart of the real-time interactive navigation method for setting an area in the present invention. As shown in Fig. 1, the real-time interactive navigation method for setting an area in the present invention includes the following steps:

Step 101, a user initiates a navigation request for a target address through a user equipment and a communication network, and the navigation request includes at least target address information and identification information of the user equipment; wherein the user equipment has a positioning function.

Here, the user equipment mainly refers to an intelligent terminal that is mobile, convenient for users to carry, and has a communication function, such as a mobile phone or a personal digital assistant with a mobile phone function and other intelligent terminals. The user equipment of the present invention also has a positioning function, that is, it can realize the function of determining its own position. Such as having at least one of the aforementioned positioning functions.

In the present invention, when the user sends the navigation request through the user equipment, the navigation request may be sent in the form of a short message. For example, put the target address information and the identification information of the user equipment into the short message, and send it to the navigation service center. The navigation service center can obtain the target address information and the like by extracting relevant information in the short message.

In the present invention, the navigation request message is also supported to be sent through a special protocol, and the format of the navigation request message can be set in advance. After the user device receives the trigger from the user, it will automatically generate a navigation request message according to the set format and send it to the navigation service center. ; The navigation service center obtains target address information, identification information of the user equipment, etc. according to the analysis of the navigation request message, and realizes the determination of the navigation route.

Step 102, the navigation service center determines the current location information of the user equipment according to the received navigation request from the user equipment, and further determines that both the current location information of the user equipment and the destination address information are in the set In the region, the navigation operation is performed according to the set navigation algorithm, and the navigation result data is generated; and the navigation result data is sent to the user equipment.

In this step, after receiving the navigation request, the navigation service center determines the current location information of the user equipment. Here, the user equipment may report its own location information through a navigation request. For example, the user equipment first determines its own location information through its own positioning function, and carries the determined location information in the navigation request and reports it to the navigation service center. The navigation service center takes the location information of the user equipment carried in the navigation request as the current location of the user equipment.

Certainly, the reporting of the current location information of the user equipment can also be realized by the user, for example, when reporting the location information of the user equipment through a short message, the current location information of the user equipment is written into the navigation request and sent to the navigation service center. The navigation service center takes the location information of the user equipment carried in the navigation request as the current location of the user equipment.

Alternatively, the navigation request is reported through the automatic voice call mode of the user equipment; specifically, when the navigation request is sent through the automatic voice call mode supported by the user equipment's own software, the automatic voice call mode is directly activated by the user. The function can realize the call with the navigation service center, so that the user equipment user can realize the report of information without jumping out of the navigation interface. The user of the navigation service center performs navigation calculations based on the destination address information provided by the user of the user equipment/and the current location information of the user equipment, using a set navigation algorithm to set the area's electronic map information. The user equipment of the present invention is equipped with software specified by the navigation center. If it can be configured in the user equipment in advance, the navigation service center can also transmit the relevant software to the user equipment when the user equipment accesses the navigation service center for the first time.

Of course, the navigation service center may also trigger the positioning function of the user equipment after receiving the navigation request from the user equipment. At this time, the navigation service center needs to support the positioning function of the user equipment, such as realizing the positioning of the user equipment through the current mobile network, that is, the navigation service center triggers the mobile network to which the mobile terminal belongs to realize the positioning of the user equipment according to the identification information of the user equipment , and use the location information obtained by positioning as the location information of the user equipment.

In this step, it is also necessary to determine whether the destination address information input by the user and the current location information of the user equipment are all in the setting area of the present invention. What the present invention realizes is navigation to popular parks, so the navigation positions realized should be In the popular park. Specifically, the navigation service center matches the location information in the electronic map information stored in its own database with the current location information of the user equipment and the destination address information in the navigation request. In the popular park, otherwise it does not exist in the popular park, and the navigation fails.

In the present invention, when the current location information and destination address information of the user equipment are both within the set area, the navigation service center performs navigation calculations based on its own electronic map information, and generates navigation result data. In the present invention, the traveling path between the user's current location and the destination address is mainly determined and provided to the user equipment. For popular parks, they are generally faced with first-time tourists, and their needs for navigation are more urgent. However, the current electronic map cannot realize navigation in this area, and the roads in the park are not public roads, and its information cannot be collected by the current electronic map. With the present invention being accurate to the level of buildings, toilets, supermarkets, and stores, the storage space of existing navigation terminals is limited. If the electronic map is accurate to the above-mentioned level, the processing speed of the terminal for such a huge database will be quite low, and the occupied storage space will also be considerable. Therefore, the present invention is aimed at areas such as tourist attractions to realize local accurate navigation.

The navigation result data of the present invention also includes some information related to the corresponding position in the navigation line, such as whether the road is under construction, whether the road is allowed to pass, the current parking situation of the parking lot, the current business information of the supermarket, the supply of gas stations, etc. Oil status information, current customer flow information of banks and post offices. The user of the user device can know what infrastructure is available at the relevant location on the current route, other scenic spots on the route, the characteristics of the scenic spot, and so on. The above location-related information will also be regularly updated and stored in the electronic map information.

Step 103, the user equipment parses the navigation result data, converts the navigation result data into a navigation route and displays it.

The user equipment parses the navigation result data, which is essentially electronic map information. If the navigation service center and the user equipment adopt mutually supported electronic map formats, the user equipment will directly parse out relevant navigation result data and display relevant navigation routes. In the present invention, it can be stipulated that the navigation service center adopts the electronic map data format supported by the user equipment, such as adopting the data format stipulated in relevant standards.

Step 104, the user equipment monitors the user's traveling route according to its own positioning function, and prompts the user whether the traveling direction is correct, and prompts the user about the relevant information of the corresponding location when the user passes the corresponding location.

In this step, the user equipment utilizes its own positioning function to locate its own location, and compares it with the navigation route to determine whether the user's traveling direction is consistent with the navigation route, and reminds the user if it is determined to be inconsistent. In the present invention, it is also supported to notify the user of the relevant information of the relevant locations involved in the traveling route according to the user's traveling route, such as notifying the user through language or through text display. Those skilled in the art should understand that information reminder based on navigation result data is a prior art, and the present invention will not describe its implementation details again.

In this step, the location-related information of popular parks includes whether the road is under construction, whether the road is allowed to pass, the current parking situation of the parking lot, the current business information of the supermarket, and the current customer flow information of banks and post offices.
