The present embodiment adopts look-at-me to control the switching of battery saving mode and station-keeping mode, controls in order and is not easy to make mistakes, and is conducive to long time period location.The present embodiment enters battery saving mode when positioning unit obtains positional information simultaneously, does not do the consumption that successional location so just further reduces electricity consumption.
In the present embodiment, location required time is obtained when the time of the setting of described positioning timing device can be satellite positioning module cold start-up; Time of described province electric timer setting can be the smaller that the time interval demand of the double location of user and satellite positioning module keep in the maximum time value of warm start.The setting-up time of certain the present embodiment province's electric timer and positioning timing device is not limited only to the time value given by the present embodiment, and the time value of the present embodiment setting is only a better implementation method of the present invention.
When locating successfully, satellite positioning module produces locating information; When locating unsuccessfully, satellite positioning module produces location failure information.
Embodiment three
In this example, obtain the time (usually at about 40 seconds) needed for location when the timing of location timer is set as satellite positioning module cold start-up, in the present embodiment, location timer is designated as T1 timer; Power saving timer is set as T4, T4 be numerical value smaller among T2 and T3 namely: T4=MIN (T2, T3).Wherein T2 is the maximum time (being generally dozens of minutes) that satellite positioning module successfully locates that this module of rear maintenance is warm start state, and T3 needs to provide the time interval of locating information (being generally a few minutes to dozens of minutes) for satellite positioning-terminal.In the present embodiment, economize electric timer and be designated as T4 timer.
First satellite positioning module start-up routine is performed as shown in Figure 2, S11-S12: start to start satellite positioning module and make it enter satnav state at terminal control platform; S12: arrange, start T1 timer; S13: then terminate start-up routine.
After executing start-up routine, satellite positioning module starts positioning work, T1 timer starts counting simultaneously, if satellite positioning module fails to realize location within the T1 time, when the T1 time arrives, T1 timer produces the failed look-at-me in location, as shown in Figure 3, S21: start to enter T1 timer interruption handling procedure, S22: provide location failure information to user, S23: control satellite positioning module and enter battery saving mode, S24: arrange simultaneously, start T4 timer, S25: then terminate this interrupt handling routine.
If satellite positioning module is located successfully within the T1 time, then enter flow process as shown in Figure 5, S41: perform satnav success interrupt handling routine, S42: stop T1 timer, T1 timer interruption is made to occur like this, S43: to provide locating information to user, S44: to control satellite positioning module and enter battery saving mode, S45: arrange simultaneously, start T4 timer, S46: then terminate this interrupt handling routine.
After entering the battery saving mode T4 time, as shown in Figure 4, S31:T4 timer interruption produces, perform T4 timer interruption handling procedure, S32: control satellite positioning module and enter positioning work pattern, S33: arrange simultaneously, start T1 timer, S34: then terminate this interrupt handling routine.
After satellite positioning module enters station-keeping mode, if locate successfully, perform the successful interrupt service routine in location as shown in Figure 3, if located unsuccessful (in the T1 time no-fix namely mean locate unsuccessfully), execution T1 timer interruption handling procedure.Above-mentioned flow process achieves satnav pattern (short time) and battery saving mode (for a long time) periodic duty, while uninterruptedly providing satellite positioning information, solve satellite positioning module due to the very large problem affecting the satellite positioning-terminal working time of power consumption when positioning work pattern.
By utilizing the warm start positioning states of satellite positioning module (as GPS, the Big Dipper, GLONASS, Galileo etc.), this method is adopted to make hand-held satellite positioning-terminal meet with little power consumption the requirement that terminal user's self poisoning and remote monitoring center uninterruptedly locate handheld terminal.Warm start positioning time of satellite positioning module generally within several seconds (as 1-3 second), and for the satellite positioning-terminal user of translational speed within tens kilometers per hour, continuous print is not needed to locate, the warm start of several seconds postpones the error producing at most tens meters positioning time, and this error range is acceptable.The hundreds of times even several thousand times of power consumption when the power consumption of usual satellite positioning module when positioning work is this module battery saving mode, if average current during certain Big Dipper module work is 60mA, and under battery saving mode, average current is 20uA, and power consumption differs 3000 times.This method makes locating module remain on warm start state (a few second just can obtain positional information when needing location under open sky), makes locating terminal overwhelming majority time service in a power-save mode simultaneously.
Localization method provided by the invention makes positioning unit be in warm start state in the most of the time, makes this module work at battery saving mode, and periodically enter station-keeping mode simultaneously and position, power consumption decreases a lot; Another advantage of the present invention is that the present invention enters battery saving mode when obtaining the positional information of terminal, does not do the consumption that successional location so just further reduces electricity consumption; The present invention adopts look-at-me to control the switching of battery saving mode and station-keeping mode, controls in order and is not easy to make mistakes, and is conducive to long time period location.
The disclosed preferred embodiment of the present invention just sets forth the present invention for helping above.Preferred embodiment does not have all details of detailed descriptionthe, does not limit the embodiment that this invention is only described yet.Obviously, according to the content of this instructions, can make many modifications and variations.This instructions is chosen and is specifically described these embodiments, is to explain principle of the present invention and practical application better, thus makes art technician understand well and to utilize the present invention.The present invention is only subject to the restriction of claims and four corner and equivalent.
