Description

A kind of satnav disposal route and satellite positioning-terminal
Technical field
The present invention relates to a kind of satnav disposal route, the invention still further relates to a kind of satellite positioning-terminal.
Background technology
Present vehicle-bone global positioning system (Global Positioning System, letter GPS claims) terminal begun in commerial vehicle to popularize gradually, its function is also become stronger day by day, and can realize comprising: functions such as electronic chart, satellite navigation, voice suggestion, scheduling arrangement, burglar alarm.And in some special commerial vehicles, for example: coach, public transit vehicle, extraordinary haulage vehicle etc., above function often still can't satisfy its needs.For example after GPS terminal entry communication flex point (for example strong jamming zone etc. is received in communication coverage, the weak zone of communication signal, communication), system can't obtain the gps data of vehicle, requires on the operation management gps data compensation of flex point in the time period to be uploaded after the vehicle communication recovery normally.Present GPS terminal also can't be realized such function.
Summary of the invention
Technical matters to be solved by this invention is exactly in order to overcome above deficiency, to have proposed a kind of satnav disposal route and satellite positioning-terminal, can realizing the compensation of the satellite location data in the communication flex point time is uploaded.
Technical matters of the present invention is solved by following technical scheme: a kind of satnav disposal route comprises the steps: the first step: open up the local datastore unit that is used to back up satellite location data on satellite positioning-terminal; Second step: satellite positioning-terminal judges whether wireless telecommunications are normal, and not the time satellite location data is backuped in the local datastore unit; Treat that wireless telecommunications recover normal, satellite positioning-terminal reports the satellite location data of backup again to Surveillance center.
The described first step and also comprise the steps: 1 between second step), satellite positioning-terminal gathers satellite location data; 2), judge whether the local datastore unit overflows, do not overflow then the current data that collect in local datastore unit are existed after the last data, if overflow then the current data that collect in local datastore unit are covered the oldest data in the local datastore unit.
Satellite positioning-terminal is judged wireless telecommunications and is just often just dynamically reported satellite location data to Surveillance center in described second step.
Comprise the steps: also after described second step that satellite positioning-terminal removes the satellite location data that has reported in the local datastore unit.
Comprise the steps: that also Surveillance center preserves the satellite location data that satellite positioning-terminal reports after described second step.
Described satellite positioning-terminal is vehicle-mounted satellite positioning-terminal.
A kind of satellite positioning-terminal comprises: the local datastore unit: be used to back up satellite location data; Processing unit: be used to judge whether wireless telecommunications are normal, and not the time, satellite location data backuped in the local datastore unit; Treat that wireless telecommunications recover normal satellite positioning-terminal reports backup again to Surveillance center satellite location data.
Satellite positioning-terminal also comprises collecting unit: be used to gather satellite location data; Data processing unit: be used to judge whether the local datastore unit overflows, do not overflow then the current data that collect of collecting unit are existed after the last data, if overflow then the current data that collect of collecting unit are covered the oldest data.
Satellite positioning-terminal also comprises: clearing cell: be used for removing the satellite location data that the local datastore unit has reported.
Described satellite positioning-terminal is vehicle-mounted satellite positioning-terminal.
The beneficial effect that the present invention is compared with the prior art is: the present invention has opened up the local datastore unit and has been used to deposit satellite location data in the communication flex point on satellite positioning-terminal, treat to upload after communication recovers the interior satellite location data of communication flex point of backup, guaranteeing provides complete satellite location data for operation management, solved because satellite location data is imperfect the problem that some application can not effectively be implemented in the operation management.
Description of drawings
Fig. 1 is the schematic flow sheet of the specific embodiment of the invention.
Embodiment
As shown in Figure 1, a kind of satnav disposal route comprises the steps:
The first step: on satellite positioning-terminal, open up the local datastore unit that is used to back up satellite location data.
Second step: satellite positioning-terminal timing acquiring satellite location data, described satellite location data comprises current location, speed and temporal information.
The 3rd step: judge whether the satellite location data on the local datastore unit overflows, do not overflow then the current data that collect in local datastore unit are existed after the last data, if overflow then the current data that collect in local datastore unit are covered the oldest data (being article one data) in the local datastore unit.
The 4th step: satellite positioning-terminal judges whether wireless telecommunications are normal, if normally just dynamically report satellite location data to Surveillance center constantly; If satellite positioning-terminal just backups to satellite location data in the local datastore unit when undesired, treat that wireless telecommunications recover normal, satellite positioning-terminal reports the satellite location data of backup again to Surveillance center.Satellite positioning-terminal is also removed the satellite location data that has reported in the local datastore unit.Can guarantee that so enough storage spaces are used to store data.
The 5th step: Surveillance center preserves processing with the satellite location data that reports.Surveillance center also judges according to the temporal information in the satellite location data that reports whether these data are flex point offset datas, and when being offset data is carried out special marking, convenient searching from now on.After satellite location data is newly received by Surveillance center, the time of the satellite location data that will upload recently with satellite positioning-terminal compares, if the time ratio of the satellite location data newly received is (time of the satellite location data that the time of the satellite location data of promptly newly receiving uploads recently early than satellite positioning-terminal) early, judge that then the satellite location data of newly receiving is the flex point offset data.Surveillance center can preserve these flex point offset datas, thereby provides complete satellite location data for operation management.
Described satellite positioning-terminal can be vehicle-mounted satellite positioning-terminal or hand-held satellite positioning-terminal.
A kind of satellite positioning-terminal comprises: the local datastore unit: be used to back up satellite location data; Processing unit: be used to judge whether wireless telecommunications are normal, and not the time, satellite location data backuped in the local datastore unit; Treat that wireless telecommunications recover normal satellite positioning-terminal reports backup again to Surveillance center satellite location data.
Described satellite positioning-terminal also comprises: collecting unit: be used to gather satellite location data; Data processing unit: be used to judge whether the local datastore unit overflows, do not overflow then the current data that collect of collecting unit are existed after the last data, if overflow then the current data that collect of collecting unit are covered the oldest data.
