The mode of associated storage may include many kinds in above-mentioned steps S13, as long as according to the historical position information of storage Environmental information associated with the historical position information can be effectively read, for example, a corresponding table can be set, The information of each typing is made as a corresponding table, includes several typing information, every typing information in each corresponding table Environmental information including typing and the historical position information with the environmental information unique association.To the general side of associated storage Formula, associated storage technology, the associated storage technology being referred in relational storage technique, details are not described herein for concrete mode.

The historical position information and the whether matched method of the current vehicle location information are judged in above-mentioned steps S14 It can be the one-to-one correspondence of longitude and latitude, or a certain range set according to longitude and latitude, the position consistency of the range covering (or In certain error) it also may determine that and match etc., it is preferable that in conjunction with azimuth, matched condition is limited, such as In the case that longitude and latitude regional scope matches, the difference of further azimuthal is judged.

In above-mentioned steps S15, the environmental information can play according to the judgement result in S14 and read information, such as: When judgement result is matches, notice reads the environmental information of storage, and broadcast interface shows the environmental information, when judgement result is When mismatch, notice broadcast interface does not have matching content, and without any, or display is without matching content etc..It is worth mentioning It is that broadcast interface can also show other content, such as this method is applied in navigation system, broadcast interface shows current guidance The electronic map of information, the electronic map are drawn by the current location information obtained and map datum etc., work as this method When determining result to match, while broadcast interface can show electronic map, shows the environmental information of storage, play boundary at this time Face includes at least two picture pages, shows electronic map and environmental information respectively, wherein the size, transparency of picture page can roots It is configured according to needs or habit.Wherein electronic map draws the technology that technology is comparative maturity, and details are not described herein.

This method only plays out the environmental information to match with current vehicle location information, and other environment letters Breath can make the environmental information of display more targeted in this way although being stored, and without automatically showing, The effects of bringing apparent contrast effect, also capable of more playing prompt road conditions.

The specific embodiment of above steps is described in detail separately below.

In embodiments of the present invention, in above-mentioned steps S12, input method may include the one or more of following methods,

S201, triggering entry time；

S205, typing current context information；And/or

S202, setting typing condition；

S203, vehicle current information is obtained；

S204, judge whether to meet typing condition；

S205, typing current context information.

The mode of environmental information described in typing may include many modes, and respective typing mode single can exist, can also To coexist, as shown in figure 4, the method for typing vehicle environmental information, such as step S201, can be led to by triggering typing event manually It crosses triggering recording device manually and typing is carried out to environment, recording device includes the follow shots equipment such as mobile phone or camera, can also be with The typing condition of the environmental information of typing is set, such as step S202, typing condition is first set, is sentenced by S204 It is disconnected, when reaching typing condition, start recording device automatically, the typing item for vehicle current information and the S202 setting that S203 is obtained Part is consistent, such as the typing condition can be time interval, then the current information obtained is time, the time interval It can be fixed, such as every 20 seconds records are primary, are also possible to unfixed；Or typing condition may be distance interval, The current information then obtained is traveling mileage, such as every 1000 meters of records are primary；Or be fixed road conditions, then what is obtained is current Information is location information, such as traveling to intersection carries out typing every time；The typing condition can also be super for acceleration Cross setting value etc., the typing condition of the corresponding setting of the current information of acquisition.

Process provides a variety of input methods, user can need to select different input methods according to different, operation Simply, flexibly, and customization is strong.

In embodiments of the present invention, as shown in figure 5, in above-mentioned steps S13, the method for the associated storage includes:

S301, the environmental information for storing typing, obtain the store path of the environmental information；

S302, it obtains and the associated historical position information of the environmental information；

S303, the store path of the environmental information and the associated historical position information of the environmental information are set as going through The Records of the Historian, which is recorded, is stored in text file.

Preferably, it will be deposited with the associated historical position information of the environmental information, entry time and the environmental information Storage path is spliced into a historical record, and every historical record is successively stored in text file.

In S31, the environmental information of typing is stored to designated space first, can be specified file, it can also be with It is a database or other different forms；Then the store path of the environmental information of storage is obtained；In S32, recording It is obtained and the associated historical position information of the environmental information while entering environmental information；In S33, the historical record may be used also To include entry time, every historical record is successively stored in preset text file.

In this method, each typing all forms a historical record, and over time, the number of typing is increasingly More, the historical record of storage is also just more and more, and each typing point stores an associated historical record, and every record includes record The longitude and latitude of fashionable user's vehicle position, the direction of movement, date and time, corresponding picture with scenes or actual road conditions Photo store path, the record of each shooting point is stored in same file in a certain order, when this text When the size of part is more than the value of a setting (this value is arranged according to the actual situation), such as 30M, 60M etc., new shooting point Record can replace the record of old shooting point.The filename for storing the record of each shooting point is arranged according to actual needs, example Such as from about it is set to navi_history_record.txt.

Every historical record is stored in order, when memory space is empty, the record of new shooting point is directly deposited It stores up into designated position, becomes first record；After the record of another new typing point generates, specific bit is arrived in additional storage In setting, become Article 2 record；The rest may be inferred；When file reaches the size of setting, the record of new shooting point can be by first Item record replacement, then come a new shooting point record can by Article 2 record replace, and so on.

The content of each historical information includes the longitude and latitude of user position, the direction of movement, day when taking pictures at that time The store path of the photo of phase and time, corresponding picture with scenes or actual road conditions；The unit of longitude and latitude is degree, general accurate 6 after to decimal point；The unit of the direction of motion is degree, is generally accurate to after decimal point 1, with due north for 0, is clockwise turned to Just, 0~360 degree of range；The format of date and time is respectively everyday and constantly every minute month in and month out every year, different Environmental information type format is also different, such as: the storage format of photo depend on specific capture apparatus, such as jpg, The photo of the storage format of some mainstreams such as bmp, png, photo name depend on specific capture apparatus, can be with date and time The filename of point name.Content as each group forms the historical record of such format: longitude, east longitude or west longitude, latitude Degree, north latitude or south latitude, driving direction, every year month in and month out everyday, when time-division every minute and second, the store path of photo.

Such as: near the south gate of Shenyang City, Liaoning Province Olympic Sports Centre, one can be formed as edge Road historical information record: 123.464694, E, 41.738390, N, 358.2,20150810,112145, sdcard/photo/ 20150810112145.jpg.Wherein: location information when typing where vehicle is 123.464694, E, 41.738390, N, 358.2, i.e., longitude and latitude be east longitude 123.464694,41.738390 degree of north latitude；Azimuth is 358.2；Entry time is 2015 21 divide 45 seconds at August 10 days 11；The environmental information of typing is picture, the entitled 20150810112145.jpg of picture, typing Vehicle environmental information store path be sdcard/photo/20150810112145.jpg, the text of storage environment information The entitled photo of part.

Historical record as the above multiple groups forms the text file of a historical record, the entitled history_ of file Record.txt reads in text file location information and current vehicle position in every historical record when judging whether matching Confidence breath compares, if judging result is matching, reads environmental information according to store path in the historical record, then It plays back.

This storage method format is simple, convenient reading and broadcasting, not only reduces the workload of programming personnel, and fault-tolerance is strong, And the size for reducing storing data of high degree, memory space is saved, this point is very important.

The storage format of every kind of environmental information is not identical, can be according to the different characteristics of different-format, to environmental information It is stored, such as；If the environmental information of typing is the text recalled the past memories, directly the text can be stored to history and remembered In record, it is associated storage with history text information, when reading historical record, directly plays the text；If environmental information Then consistent with the memory module of above-mentioned photo for memory modules such as music, recording or videos, the filename for storing music can be with For music, store path is set as sdcard/music/20150810112145.mp3, the storage of other environmental informations In the manner described above, details are not described herein for concrete mode.
