Embodiment
With reference to Fig. 1, this figure is a kind of lamp post structure schematic diagram that first embodiment of the invention provides, and is " 110 " printed words in the oval circle in lamppost top, and the below is the numeral of a longitudinal arrangement." 110 " printed words usually spraying are redness, " 110 " are that police sign also is the telephone number of warning usefulness, and 7 bit digital have comprised the street locations information of some lampposts longitudinally, as: the 1st bit digital represents each district, incity, city, represent Futian District such as " 1 ", " 2 " represent Luohu District etc.; The 2nd represents road to the 4th bit digital; The 5th represents that to the 7th bit digital (position is by single, double number expression for lamppost and position.That is: east-west road, the southern side is odd number, the north side is even numbers; The road of south-north direction, east side are odd number, and the west side is even numbers) etc. much information.Illustrate: " 1020004 " refer to the 4 signal lamp posts in Futian District Huaqiangbei Road west side.It is unique that this numbering can be set in a city, rather than unique in the whole nation or global range, can avoid like this causing this numbering length longer, and inconvenience is used.
Be posted thing for fear of lamppost numbering and cover, can be with the set positions of lamppost numbering spraying in the about zone more than 2.5 meters of lamppost.In order on road, to be easy to see the lamppost numbering, preferably the lamppost numbering is sprayed on the zone of lamppost approximately inclined to one side miter angle to the road inboard in addition, even the vehicle that travels like this on road is also easier seen the lamppost numbering.
Can be in spraying lamppost when numbering or afterwards, gather positional information corresponding to lamppost.As carrying GPS equipment, the numbering that lamppost is corresponding and the longitude and latitude data record of collection are got off.Certainly such collecting work amount is larger, can also adopt some simply but not too accurate method.As on the street lamppost of spraying numbering distribute more even, can on a street, only gather the latitude and longitude information corresponding to lamppost numbering at two ends, longitude and latitude data corresponding to lamppost between the two ends, street numbering can be asked according to equally distributed characteristic with the longitude and latitude at two ends and wait score value to calculate, and have saved so the one by one trouble of collection.If road is longer, perhaps bend is more, and some collection points can be set between two ends more, and particularly between the bend, then calculating waits score value to calculate the longitude and latitude data of lamppost numbering between adjacent collection point.
Except using the Arabic numerals, can also use English alphabet etc. during lamppost is numbered in addition.As: " G14712272 ".In addition, except lamppost spraying reference numeral, those of ordinary skills are knowing on the basis of the present invention, easily expect other execution modes of the present invention, for example: can also with lamppost similarly fixed object widely distributed, that have the regularity of distribution spray reference numeral, similarly fixed object such as electric pole, building, trees etc.Make the larger effect of urban operating mechanism performance of having invested.
The operation flow of a cover based on the positional information of longitude and latitude or urban addresses all set up in the service that general position is relevant, if set up separately a cover based on the operation flow of lamppost numbering, cost is higher again.Can number corresponding longitude and latitude and/or urban addresses by gathering lamppost in the embodiment of the invention, and be stored in the lamppost location database of server.If comprise the lamppost numbering in the service request that then receives, then inquire about this database, obtain longitude and latitude corresponding to lamppost numbering or the positional information of urban addresses, then utilize corresponding positional information to carry out the processing of operation flow.
With reference to Fig. 2, this figure is that second embodiment of the invention realizes comprising the steps: based on the service procedure figure of lamppost numbering
Can certainly directly city identification information and lamppost numbering be included in the service request together, can make like this server process efficient higher.As lamppost being numbered the part as urban addresses (CivicAddress), when processing, only use country, province, city and lamppost number information, remaining information can be ignored, because very accurate in the position that the inside, city lamppost numbering is corresponding, other address information such as street have all no longer needed.
Receive in addition arbitrary go-between entity such as SIP (Session Initiation Protocol) acting server (Proxy) in the communication network of the service request that comprises lamppost numbering, can send location resolution request to the server that stores the lamppost location database, comprise the lamppost numbering in this location resolution request, the go-between entity receives the response message that comprises this lamppost numbering correspondence position information, then the go-between entity carries out the relevant service routing in position etc. (police station that routes requests to this position of administration during such as urgent call processes) according to the positional information of reality, the network entity of down hop such as other acting servers or final recipient the more specific location information that obtains can also be inserted in the service request, so that can directly utilize concrete positional information to process.And needn't resolve positional information corresponding to lamppost numbering again.
