Detailed description of the invention
For making the purpose of the application, technical scheme and advantage clearly, below in conjunction with the application specific embodiment and corresponding accompanying drawing, technical scheme is clearly and completely described。Obviously, described embodiment is only some embodiments of the present application, rather than whole embodiments。Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of the application protection。
The navigation procedure that Fig. 1 provides for the embodiment of the present application, specifically includes following steps:
S101: terminal, according to the map obtained from server, generates navigation way。
In the embodiment of the present application, described terminal can be mobile terminal, includes but not limited to: mobile phone, navigator, panel computer, intelligent watch etc.。Described server can be to provide the server of the application of navigation Service, and terminal obtains navigation Service by this application。
After this application of terminal operating, can obtain, from server, the map being currently located city。Concrete, terminal can be passed through GPS module and self is positioned, and the positional information oriented is sent to server, and server then can send corresponding map according to this positional information to terminal。Then, terminal according to the departure place of user's selection and destination, can generate navigation way, and navigate for user on the map obtained。Wherein, terminal can generate corresponding navigation way according to preset rules, described preset rules such as: from origin to destination the shortest route of distance, by way of the minimum route etc. of traffic lights。
Certainly, terminal also can obtain map from server in advance and preserve, then the map that regular update has preserved, rather than only just obtain map from server in real time when needs navigation Service, so, terminal is when needs generate navigation way, can not interact with server, it is possible to improve navigation efficiency。
S102: terminal, based on short-range wireless communication protocol, receives the real-time routes characteristic information that information collecting device sends。
In the embodiment of the present application, after terminal generates navigation way according to the map, can start to navigate for user。The map that terminal is acquired would generally represent the general information of each route; including route name, route specification, route start-stop position, traffic rules mark etc.; these information are more fixing; seldom change; generally update with the renewal of map; and in actual applications; under special scenes; other factors are also had the passed through state of map course to produce to affect over the ground; map does not represent the relevant information of this kind of factor, thus causing that the navigation way that terminal generates according to the map is not necessarily reliable。
Such as, when raining in torrents, the road in city may produce hydrops, and the section that particularly physical features such as bridge opening, tunnel, depression is relatively low, the degree of depth of hydrops even may result in vehicle and pedestrian is impassable, that is, these sections become obstacle section。In such a scenario, owing to not representing the real-time road surface water level information in each section on map, therefore, the navigation way that terminal generates according to the map may comprise this obstacle section, thus, this navigation way is insecure。
By above-mentioned explanation, in the embodiment of the present application, this kind of factor also can be taken into account by terminal when generating navigation way according to the map, or, terminal also first can generate navigation way according to the map, and the navigation way generated is revised by relevant information further according to this kind of factor in real time。Concrete, the provider of navigation Service can determine collection point on each section, and at each collection point configuration information collecting device, to gather the relevant information (hereinafter referred to as real-time routes characteristic information) of this kind of factor, then, the real-time routes characteristic information collected uploaded onto the server preservation by information collecting device, when server provides navigation Service for terminal, then map and saved real-time routes characteristic information (hereinafter referred to as depositing routing characteristics's information) can be sent jointly to terminal, or, server also can by map with deposited after routing characteristics's information is integrated and be then forwarded to terminal。Thus, terminal according to the map obtained with deposited routing characteristics's information, can generate navigation way, the factor that the navigation way owing to now generating does not consider before considering, thus the navigation way that now generates to compare the navigation way generated under the prior art more reliable。
Further, owing to terminal is based on what cordless communication network that common carrier provides and server communicated, therefore, when the wireless communication network signal of terminal position is bad, terminal possibly cannot obtain from server in time and deposit routing characteristics's information, moreover, when the wireless communication network signal of information collecting device position is bad, information collecting device possibly cannot upload the real-time routes characteristic information of collection in time to server, causes that the real-time depositing routing characteristics's information preserved on server is poor。And the such as change of this kind of real-time routes of road surface water level information characteristic information is very rapid, in this case, in order to ensure the real-time of the acquired routing characteristics's information of terminal, information collecting device can also be directly based upon short-range wireless communication protocol, the real-time routes characteristic information gathered is sent to terminal, accordingly, terminal receives this real-time routes characteristic information, for subsequent processes。
S103: this navigation way, according to the real-time routes characteristic information received, is modified by terminal。
In the embodiment of the present application, according to the explanation in step S102, depositing routing characteristics's information compared to terminal from what server obtained, the real-time of the real-time routes characteristic information that terminal receives from signal collecting device is better, more can embody the passed through state that ground map course is up-to-date。Therefore, terminal is after receiving real-time routes characteristic information from signal collecting device, it is likely to need before according to the map obtained from server, or according to the map obtained from server with deposited routing characteristics's information, the navigation way that generated (namely, current navigation way) it is modified, to ensure the reliability for the navigation way for user's navigation。
By above-mentioned method, when terminal determines navigation way, consider the real-time routes feature impacts on each section trafficability such as such as road surface water level, and owing to real-time routes characteristic information can be gathered by signal collecting device, and it is transmitted directly to terminal, therefore, terminal can generate navigation way according to the routing characteristics's information of depositing obtained from server, even and if when wireless communication network signal is bad, terminal is also by the mode of short-distance wireless communication, directly obtain real-time routes characteristic information to revise current navigation way from information collecting device, thus, terminal can determine that reliable navigation way, for navigating for user。
In the embodiment of the present application, all illustrate for practical application scene with described factor for road surface water level below。In such a scenario, described real-time routes characteristic information is real-time road surface water level information, and described routing characteristics's information of depositing is to have deposited road surface water level information。Can be specifically the equipment such as level sensor for gathering the information collecting device of real-time road surface water level information, multiple level sensors can be respectively arranged at each section by the provider of navigation Service, the especially needed section being arranged on easy hydrops, section as relatively low in physical features such as bridge opening, tunnel, depression, the real-time road surface water level information in each section gathered can be uploaded to server and save as and deposit road surface water level information by level sensor。
In the embodiment of the present application, in above-mentioned steps S101, terminal, according to the map obtained from server, generates navigation way, specifically include: terminal determines departure place and destination on the map obtained, and deposited road surface water level information from server acquisition, then, deposit road surface water level information according to what obtain, determine obstacle section, the obstacle section determined is got rid of from map, then the map behind the section that removes barriers is determined route from origin to destination, as the navigation way generated。
General, departure place is defaulted as terminal positioning self position current out by terminal, and certainly, departure place and destination can also be selected in terminal by user or input。Terminal can determine that the route topology in this body of a map or chart according to the map obtained from server。Wherein, in described route topology, intersection point that route intersects or the end points of route, can be described as the node in route topology, the line segment between each node is section。Now, all sections in route topology are all defaulted as state of can passing through, and then, terminal deposits road surface water level information according to what obtain from server, it may be determined that go out impassable section, that is, obstacle section。And then, terminal is for each obstacle section, when the water level information collection point, road surface causing this obstacle section impassable is positioned at node, then all sections intersecting at this node can be got rid of route topology, when the water level information collection point, road surface causing this obstacle section impassable is not at node, can only the section at this place, collection point be got rid of route topology。Then, terminal by the departure place in the route topology behind the section that removes barriers and destination, can also serve as two nodes, calculates the minimal path between the two node based on routing algorithms such as such as dijkstra's algorithms, as the navigation way generated。Certainly, according to default path policy, terminal can also select other routing algorithm to calculate corresponding navigation way。
It should be noted that, city has surface road, also overpass, subway etc. is had to be positioned at the route of Different Ground height, circuit corresponding to surface road and overpass, subway is not likely to be actual intersecting, intersect when being only project to map plane, that is, only projection is intersected, in the embodiment of the present application, described node refers both to the actual intersection point intersected of route。
Further, the road surface water level information that information collecting device gathers can comprise some parameters, and one of them being used for judging, can the pass through key parameter of state of section is called road surface water level parameters below, that is, the degree of depth of surface gathered water。Then terminal deposits routing characteristics's information according to what obtain, determine obstacle section, specifically include: terminal is deposited the water level information of road surface from what obtain, extract the road surface water level parameters in each section on map, and for each section on map, when the road surface water level parameters in this section is more than predetermined threshold value, then this section is defined as obstacle section。Wherein, described predetermined threshold value can be set according to the chassis height of oneself vehicle by user so that this vehicle will not stop working because of water inlet when road surface water level parameters is not more than the sections of road of predetermined threshold value。
In the embodiment of the present application, owing to the road surface water level information of depositing on server is uploaded by information collecting device, therefore, depositing road surface water level information and to lag behind level sensor in real-time and currently gather and the real-time road surface water level information not yet uploaded on server, if information collecting device is not real-time synchronization is uploaded to server, but according to prefixed time interval, regularly upload, then deposit road surface water level information more delayed in real-time。
Therefore, in order to improve the real-time of the acquired road surface water level information of terminal, information collecting device can comprise short-range wireless communication module, for be transmitted directly to by the real-time road surface water level information gathered can each terminal in communication range。Then for above-mentioned steps S102, terminal receives the real-time routes characteristic information that information collecting device sends, specifically include: terminal is based on short-range wireless communication protocol, search information collecting device, and set up short-distance wireless communication with the information collecting device searched and be connected, then obtain information collecting device to be connected by the short-distance wireless communication set up, the real-time road surface water level information of transmission。Wherein, described short-range wireless communication protocol can be bluetooth (Bluetooth) agreement, purple honeybee (ZigBee) agreement etc., accordingly, it can be Bluetooth communication connection, ZigBee communication connection etc. that described short-distance wireless communication connects, the communication range of commonly used short-distance wireless communication is within hundred meters, when strengthening transmitting power, this communication range also can be extended to 1～2 kilometer。
Owing to information collecting device and each terminal can not rely on the cordless communication network that common carrier provides, and be based on short-range wireless communication protocol and be made directly communication, therefore, even if the signal of communication of the cordless communication network that common carrier provides is bad, as long as terminal enters in the communication range of information collecting device short-distance wireless communication, still can obtain real-time road surface water level information from information collecting device in real time, thus, in real time current navigation way can be modified accordingly follow-up, obtain more reliable navigation way。
At this, for described short-range wireless communication protocol for Bluetooth agreement, information collecting device is set up with terminal short-distance wireless communication and is connected the process of (that is, Bluetooth communication connects) and illustrates。
First, information collecting device and terminal are both needed to open Bluetooth function, information collecting device is as monitoring side, the facility information of self is broadcasted in the communication range of self, terminal searches for adapting appts as active connection side, after terminal enters the communication range of information collecting device, can receive the facility information of information collecting device broadcast, information collecting device, by the analysis to this facility information, can be defined as adapting appts by terminal。Then, terminal is set up Bluetooth communication with this information collecting device and is connected, concrete, the terminal facility information according to this information collecting device, generate the general unique identifier (UniversallyUniqueIdentifier, UUID) of this information collecting device, and using this UUID as parameter, in the creatRfcommSocketToServiceRecord method of incoming BluetoothDevice class, then can obtain the BluetoothSocket object that the method returns；Accordingly, information collecting device corresponding for this UUID also can generate same UUID according to the facility information of self, then using this UUID as parameter, in the listenUsingRfcommWithServiceRecord method of incoming BluetoothAdapter class, then can obtain the BluetoothServerSocket object that the method returns, and for this object reference accept method, then can obtain the BluetoothSocket object being in listening state that the method returns。So far, this information collecting device and terminal connection establishment are ready for, and then, terminal obtains BluetoothSocket object reference connect method for oneself, namely, sending connection request to this information collecting device, after this this connection request of information collecting device success response, this information collecting device and terminal Bluetooth connection establishment complete。
It should be noted that terminal can also search for information collecting device in non real-time, but only under special scenes, during as rained in torrents, the short-distance wireless communication function that ability is opened terminal by user searches for information collecting device in real time, it is thus possible to reduce the resource consumption of terminal。
Further, after terminal receives the real-time road surface water level information that information collecting device sends, it is possible to according to this real-time road surface water level information, redefine obstacle section。Obviously, this information collecting device can only collect the road surface water level parameters at self collection point, place place, therefore, the road surface water level parameters of this collection point can only be rejudged by terminal, if depositing road surface water level information according to what obtain from server before terminal, judge that the road surface water level parameters of this collection point is less than predetermined threshold value, so that it is determined that go out this section, place, collection point not for obstacle section, and now according to the real-time road surface water level information obtained from information collecting device, rejudge out the road surface water level parameters of this collection point more than predetermined threshold value, then obstacle section is determined in this section, place, collection point。In this case, if this section, place, collection point is positioned on current navigation way, then current navigation way can be modified, namely, this obstacle section is got rid of from map, then, route is from origin to destination determined by the map after getting rid of this obstacle section, as revised navigation way, and navigate for user according to revised navigation way。
Additionally, except gathering real-time road surface water level information, information collecting device can also with corresponding sensor and/or monitor, collection can affect the real-time routes characteristic information of other factors of navigation circuit, such as, road snow information during lower severe snow weather, the information of vehicle flowrate etc. in traffic peak period, then terminal according to this kind of real-time routes characteristic information obtained from information collecting device, can generate or revise out more reliable navigation way。
The detailed process of the navigation that Fig. 2 provides for the embodiment of the present invention, specifically includes following steps:
S201: terminal obtains map from server and deposited road surface water level information, and wherein, this has been deposited road surface water level information and has been: gathered by information collecting device and upload onto the server the real-time road surface water level information preserved。
S202: determine departure place and destination on the map obtained。
S203: deposit routing characteristics's information from what obtain, extracts the road surface water level parameters in each section on map。
S204: for each section on map, when the road surface water level parameters in this section is more than predetermined threshold value, is then defined as obstacle section by this section。
S205: each obstacle section determined is got rid of from map。
S206: determine route from origin to destination on the map behind the section that removes barriers, as the navigation way generated, and navigates for user。
S207: in navigation procedure, based on short-range wireless communication protocol, searches for information collecting device in real time。
S208: set up short-distance wireless communication with the information collecting device searched and be connected。
S209: obtain information collecting device and connected by the short-distance wireless communication set up, the real-time road surface water level information of transmission。
S210: according to the real-time routes characteristic information obtained, redefine obstacle section。
S211: if the obstacle section redefined out, differ with the obstacle section determined when generating described navigation way, then according to the obstacle section redefined out, described navigation way is modified。
The another kind of navigation procedure that Fig. 3 provides for the embodiment of the present application, specifically includes following steps:
S301: terminal obtains map and road surface water level information from server。
Wherein, described road surface water level information can be acquired by the level sensor being set in advance in each section, and in real time or according to set interval be uploaded to server preserve。
S302: according to the map obtained and road surface water level information, generates navigation way。
Pass through said method, owing to terminal is when generating navigation way, according to the route topology that the road surface water level information obtained and map provide, consider the impact on the trafficability in section each in route topology of this road surface water level information, thus, road surface water level is defined as obstacle section higher than the section of predetermined threshold value, and regeneration navigation way after getting rid of route topology, therefore, the navigation way that terminal now generates is more more reliable according only to the navigation way of map generation than in prior art。
It addition, in the embodiment of the present application, navigation way except generating in terminal, it is also possible to generates on the server。Concrete, when terminal needs navigation Service, departure place information (positional information as current in self) and destination information can be sent to server, then server can search map and corresponding road surface water level information, then calculate for terminal and generate navigation way, then this navigation way is sent to terminal, thus, terminal can directly use the navigation way received to be navigated, it is possible to improves the navigation efficiency of terminal。
