Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
The present embodiment, by position encoded technology, extends to an acceptable scope two known points, in the time that user recommends/collects transfer plan, and the scope at storage starting point and terminal place.When inquiry next time, even if what will search for is not two current points, as long as starting and terminal point can be fallen in existing scope, just think that current transfer result is available.So, can be just the search between region unit point-to-point search extension, thereby improve the accuracy that user recommended/collected the hit rate of inquiry and do not affect result.
Recommendation and the querying method process flow diagram of the public transport interchange circuit that Fig. 1 provides for the embodiment of the present invention, comprise the following steps:
After step 101, user's recommended line, submit the simple description of circuit and the latitude and longitude information at starting and terminal point station to server.Simple the circuit that comprises user and need to take is described, on this circuit the information such as station number, transfer website, rationale for the recommendation of process, these descriptors are configurable, as the details information storage of recommend/collection scheme.The latitude and longitude information of starting point and terminus is necessary, is the critical field that user inquires about.
The information that step 102, server process user are submitted to: the longitude and latitude of inception point and terminus is carried out position encoded, by coding, two points are expanded to two region units.Two points of tellurian longitude and latitude scope, through repeatedly after two points, can narrow down to the region of enough little (this scope is configurable), each longitude and latitude can drop in corresponding region unit, and in two timesharing for several times, has also recorded the coding of each region unit.Like this, just can use the method to calculate the region unit at place when getting a longitude and latitude, the coding of current region piece just can be thought the position encoded of this point.
The simple description that step 103, server are submitted the position encoded and user of inception point and terminus to is deposited in database.So far, user recommends part to complete.
Step 104, when checking recommendation, user submits the longitude and latitude of inception point and terminus to.
Step 105, server carry out position encoded to the longitude and latitude of inception point and terminus, and use these two position encoded data of going in matching database, be the position encoded of inception point in the position encoded matching database of inception point, in the position encoded matching database in terminus, the position encoded of terminus (just can guarantee that the inception point of submission and the inception point of recommendation are in the same area like this, and then the side-play amount of guaranteeing position is unlikely to excessive, herewith manage terminus), coupling data out just can be thought available recommending data.And the simple description of submitting in step 101 just can be used as the description use of recommended line, starting and terminal point station is position encoded as key word of the inquiry, simple description as recommending details.
