Charge road-net node relational model schematic diagram in chart database as shown in Figure 3, it is public with Guangdong part high speed below
In for website, illustrate the mode of building charge road-net node relational model:
1) network entity that satisfies the need first is analyzed, and the mapping model of road network entity and chart database is established.1. figure is got the bid
Circle indicates phantom station, for describing two highway intermediate nodes or tie point.The circle presentation-entity of figure acceptance of the bid 2. is received
Take station.The circle of figure acceptance of the bid 3. indicates identification point.Two-way connectivity between standing is connected with four-headed arrow, the unidirectional arrow of unilaterally connected
Head connection, the attribute of mileage and rate as connected relation.
2) region of figure acceptance of the bid 4. is routing node, is made of two phantom stations, is extensively to start high speed and West 2nd Ring Road in reality
The interchange in south, physical location are identical.To guarantee that the connectivity of figure need to create when constructing model and adhere to two road separately
Node is connected between node with four-headed arrow, and due to being same position, the mileage and rate being connected in attribute are 0.
3) figure acceptance of the bid region 5. is identification point, due to identification point at a distance from the charge station of front and back and mileage is unknown, still
It is then bound to by the identification point by its corresponding front and back charge station.Therefore, in settable identification point and front and back charge station
Rate and mileage between any one are 0, and the expense with front and back charge station is set as with the rate and mileage of another charge station
Rate is identical with mileage.Such as figure: it is 5600 meters that company, which extensively starts the mileage between red stove, and rate is 300 points, therefore settable company extensively starts
Mileage between two E1 of west is 5600 meters, and rate is 300 points, and the mileage and rate between two E1 of west and red stove are 0.According to this
Rule, model construction of the achievable identification point in chart database.
4) region of figure acceptance of the bid 6. is infeasible paths.For infeasible paths, need to find next reachable charge station,
Phantom station or identification point, and establish connected relation.Such as figure: even West 2nd Ring Road south and gold are white unreachable, cannot establish connected relation, even
West 2nd Ring Road and wide bright E1 are reachable, and for the connectivity for guaranteeing road network, even West 2nd Ring Road is southern need to establish connected relation with wide bright E1.Due to wide
Bright E1 is identification point, even the southern mileage and expense that may be configured as the even city West 2nd Ring Road Nan Yuhe with the mileage and rate of wide bright E1 in West 2nd Ring Road
Rate.
5) and so on, the building of achievable on national network charge road-net node relational model.
In one embodiment, as shown in figure 4, the flow chart that charge road-net node relational model stores in chart database can
To include following several steps:
Step 1: obtaining charge station, phantom station, identification point information, from road network entity with the joint form in chart database
It is stored.Section coding, coding of standing, station name are stored as the attribute of node.
Step 2: the charge station in same section, phantom station, identification point being ranked up by station sequence, according to Fee Schedule in section
Judge whether adjacent charge station is connected to, connection is then stored connected relation with the relationship in chart database, is not connected to, is looked into
The connected relation with next charge station is looked for, until finding the charge station of nearest connection.Mileage, rate, section coding, volume of standing
Code is stored as the attribute on side.
Step 3: the record in traversal routing node table, two phantom stations for including by routing node establish connected relation,
It is inserted into chart database in the form of relationship.Mileage, rate, section coding, coding of standing are stored as the attribute on side, mileage
It is 0 with rate.
Step 4: the record in traversal identification point table establishes the connected relation of identification point Yu front and back charge station, with relationship
Form is inserted into chart database.The mileage and rate at identification point and consumption charge station are set as mileage and rate with front and back charge station
Equal, the mileage and rate of identification point and rear charge station are set as 0.
Further, with newly-built highway be open to traffic successively and the revocation of existing charge station, in chart database
Charge road-net node relational model can also be updated according to the setting period, and the method for update can be with are as follows: exploitation is corresponding in advance
More new interface, realize the quick update of node, relationship and attribute；Based on these more new interfaces, existing receipts are deleted first
Take road-net node relational model；Secondly charge station, phantom station, identification point information are obtained from road network entity, call chart database
Node create interface, complete the addition of node；Third: it from the connectivity for searching adjacent charge station in section in rate, calls
The relationship of chart database creates interface, completes the creation of adjacent charge station's connected relation；4th: correspondence is found out from routing node
Phantom station, call chart database relationship create interface, complete phantom station connected relation creation；It is last: from identification point
Front and back charge station is found out, the connected relation of identification point Yu front and back charge station is established, so far, road-net node relational model has updated
At.
Based on the charge road-net node relational model of chart database storage, interface journey can be calculated by corresponding rate
Sequence writes rate using Java language and calculates interface, and by incoming access station, outlet station and identification point information, system returns to phase
Corresponding mileage and rate, when access station, outlet station information are lost, the rate and mileage that system returns are 0.External program tune
When calculating interface with rate, it need to only be passed to access station, outlet station coding, identification point coded sequence or access station, outlet station and compile
Code, outlet station coding, identification point coded sequence, can the corresponding mileage of quick obtaining and rate.The specific current expense of high speed
The schematic diagram of determination process can also be with reference to shown in Fig. 5.
In some scenes, after reception inquiry request message, it is also necessary to judge that the identification point in current query information is
It is no for sky, if identification point be it is empty if shortest path restored according to inlet/outlet station information, otherwise according to inlet/outlet station information and
Identification point restores the shortest path of approach designated identification point.
Using above-mentioned charge road-net node relational model construction method, charge road-net node relational model, road can solve
The problems such as storage of net node relationships model and update, the Shortest Path Searching based on weight and specified node and rate calculate.It is logical
It crosses network entity data of satisfying the need to be analyzed, node, pass in charge station, identification point, phantom station and its connectivity and chart database
System, attribute are consistent, can fast implement charge road-net node relational model based on chart database.Neo4j provide Java,
.Net, the multilinguals second development interface such as PHP is stored and is updated convenient for data model.Rate calculating parameter passes through node, pass
The mode of system and attribute is stored in chart database, forms networked fee collection path profile.In the APOC storing process library of chart database
The path search algorithms such as Dijkstra, A*, D* are encapsulated, can go out pass through the shortest path of designated identification point with quick search, from
And further calculate pass cost.The sharpest edges of chart database are to store the node and relationship of magnanimity, and from the node of magnanimity
With shortest path is rapidly found out in relationship.
Advantage using the determination method of the current expense of above-mentioned high speed includes: that (one) data model is simple, and scalability is strong；
(2) using chart database storage charge path profile, data volume greatly reduces；(3) using chart database store adjacent charge station,
The connected relation and rate of phantom station calculate weight, and amount of storage substantially reduces；(4) rate calculated performance is superior, on national network to take
Rate calculates time-consuming within 10ms；(5) rapid rate that can solve pahtfinder hard calculates.
It should be understood that for the various method embodiments described above, although each step in flow chart is according to arrow
Instruction is successively shown, but these steps are not that the inevitable sequence according to arrow instruction successively executes.Unless having herein bright
True explanation, there is no stringent sequences to limit for the execution of these steps, these steps can execute in other order.And
And at least part step in the flow chart of embodiment of the method may include multiple sub-steps or multiple stages, this is a little
Step or stage are not necessarily to execute completion in synchronization, but can execute at different times, these sub-steps
Perhaps the execution sequence in stage be also not necessarily successively carry out but can with the sub-step of other steps or other steps or
At least part in person's stage executes in turn or alternately.
