Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, show the flow process of sending method one embodiment of electronic chart of the present invention locus, specifically may further comprise the steps:
Step S101: obtain spatial positional information;
Obtain before the coded data, at first will obtain certain any positional information.The positional information that obtains this arbitrfary point can be selected one of following two kinds of modes for use:
The one, point is got on electronic chart;
The 2nd, obtain by the GPS orientator.Electronic chart can directly receive the gps coordinate value that the GPS orientator obtains, and also can receive the gps coordinate value of user according to the display result input of GPS orientator.
Step S102: judge whether spatial positional information is offset coordinates, if change step S104; Otherwise, change step 103;
Step S103: call national special-purpose coordinate offset handling implement, above-mentioned spatial positional information is converted to offset coordinates;
Because obtaining spatial positional information has two kinds of modes, the location point for point on map is got can directly read the offset coordinates on this electronic map location; And, just need after coordinate offset is handled, carry out the scrambled computing again by the positional information (longitude and latitude) that location instrument obtains, therefore, above-mentioned steps S102 and S103 are not the necessary step of present embodiment.
Step S104: above-mentioned spatial positional information is carried out scrambled handle, generate coded data;
In this preferred embodiment, coded data adopts 12 fixed length numeric strings, encryption method is specially: to the processing that rounds up of the longitude in the above-mentioned spatial positional information, latitude value, keep 4 bit digital behind the radix point, 10000 times of the longitude after will handling then, latitude value expansions; If described longitude more than or equal to 1000000, then deducts 1000000 with longitude; If above-mentioned longitude, latitude value are less than 6, then add 0, polishing 6 figure places on the numerical value left side; Then, above-mentioned longitude, latitude value are spliced into 12 figure places, and rearrange, generate coded data by predetermined queueing discipline.If the positional information on the electronic chart is not a longitude and latitude, also can be converted into longitude and latitude after, obtain coded data through scrambled again.
About the problem of algorithm field of definition scope, the manageable longitude scope of said method is east longitude 60 degree～east longitudes 160 degree, north latitude 0 degree～north latitude 90 degree.This longitude and latitude scope can comprise the territory scope of China fully, because electronic chart is a product that the territory is very sensitive, so present embodiment can be handled the data of this country fully.As: the longitude and latitude of certain locus is north latitude 19 degree 32 minutes and 12 seconds (N19 ° of 32 ' 12 "); 44 minutes 34 seconds (E123 ° of 44 ' 34 ") of east longitude 123 degree, when handling, earlier with it by original degree every minute and second formal transformation degree of being, i.e. 19.5667 ° and 123.8178 ° (round off keeps 4 position effective digitals behind the radix point).Then latitude 19.5667 is expressed as 195667, longitude 123.8178 is expressed as 1238178; And then whether judge longitude greater than 100000, latitude is whether numerical digit is less than six.
Step S105: above-mentioned coded data is sent to the terminal that needs communal space positional information;
In addition, in the further preferred embodiment of present embodiment, also comprise following verification step:
Step S106: receive the identifying code that the spatial positional information shared terminal returns;
Step S107: above-mentioned identifying code is carried out decoding processing, and reduction becomes locus coordinate (offset coordinates), and identifies the position of this spatial positional information representative that restores on electronic chart;
Step S108: compare with the former home position in the electronic chart, if position consistency is then returned the checking correct information; Otherwise, return authentication failed information.
With reference to Fig. 2, show the flow process of method of reseptance one embodiment of electronic chart of the present invention locus, specifically may further comprise the steps:
Step S201: received code data;
Step S202: whether the form of judging above-mentioned coded data is correct, if change step S203; Otherwise, return error message, process ends;
In this preferred embodiment, coded data adopts 12 fixed length numeric strings, if above-mentioned coded data length is incorrect, or comprise other characters outside the numeral in the coded data, the coded data mistake is described, can be back to transmit leg to error message after, direct process ends.
Step S203: above-mentioned coded data is carried out decoding processing, the reduction spatial positional information;
This preferred embodiment adopts following method decoding to coded data: coded data is rearranged by predetermined contrary queueing discipline, split out longitude, latitude value; If longitude is less than or equal to 600000, then longitude is increased by 1000000; With longitude, latitude value divided by 10000, as the longitude and the latitude offset coordinates of this spatial positional information.
Step S204: on electronic chart, identify corresponding position according to above-mentioned spatial positional information.
Step S205: the offset coordinates that obtains this home position by electronic chart;
Step S206: above-mentioned offset coordinates is carried out scrambled handle, generate identifying code;
Step S207: the transmit leg that above-mentioned identifying code is sent to this spatial positional information is verified.
Need to prove, above-mentioned transmit leg can be connected directly information such as transmission coded data, identifying code by the communication that both sides set up with the take over party, also can transmit by other modes such as note, phones, and then on electronic chart, import relevant information by the interface that system provides, to this, the embodiment of the invention does not limit.For non-direct mode, the correctness of coded data can agreement by both party judge directly that therefore, step S202 is not that the method for reseptance embodiment of above-mentioned electronic chart locus is necessary.
In addition, the above-mentioned positional information that is processed as coded data all is the coordinate data through migration processing, is not the precise coordinates data; Coded data is decoded as the also coordinate data after the migration processing just of positional information.So such data fit country is to the security stipulation of locus planimetric coordinates data.
For aforesaid each method embodiment, simple in order to describe, so it all is expressed as a series of combination of actions, but those skilled in the art should know, the present invention is not subjected to the restriction of described sequence of movement, because according to the present invention, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art should know that also said method embodiment all belongs to preferred embodiment, and related action and module might not be that the present invention is necessary.When not needing to verify in the transmittance process of spatial positional information, the step S106 among the sending method embodiment of aforesaid space position～S108 can omit, and the step S205～S207 among the method for reseptance embodiment of locus can omit.
