Described positioning unit 101 is used for positioning user's initial position, obtains the coordinate information that initial position is corresponding；
Described main control unit 102 is used for controlling positioning unit in a dormant state；
Described sampling unit 105 is for, from initial position, sampling to the movement locus of user with a preset sample frequency, obtain and record the sample information of some sampled points；
Described computing unit 103, for the sample information according to some sampled points, calculates the vector shift of user current location and initial position；
Described judging unit 104 is for judging that whether the user current location vector shift with initial position is more than predetermined threshold value, if then sending the first signal to main control unit, does not otherwise send the first signal to main control unit.
When using low-power consumption positioner, first positioning unit 101 positions user's initial position, obtains the coordinate information that initial position is corresponding.In the present embodiment, positioning unit is GPS module.After GPS module sets up communication connection with base station, user can accurately know the coordinate position that initial position is corresponding.Then main control unit 102 controls positioning unit in a dormant state.After positioning unit completes initial alignment, it is possible in a dormant state, thus reducing the power consumption that user moves in preset range.
Then sampling unit 105 is from initial position, with a preset sample frequency, the movement locus of user is sampled, and obtains and record the sample information of some sampled points.Described sample information includes the sampling order of each sampled point.Described sampling unit can be sensor, and described sensor can be integrated in smart machine, it is also possible to is separately provided independent of smart machine.Described sample information includes the current sampling point vector shift compared to a upper sampled point.In the present embodiment, the preset sample frequency of described sampling unit is 0～120 sampled point/second.Main control unit can also be connected with sampling unit, for arranging the preset sample frequency of sampling unit.
The then computing unit 103 sample information according to some sampled points, calculates the vector shift of user current location and initial position.In the present embodiment, " computing unit sample information according to some sampled points; calculate the vector shift of user current location and initial position " including: the vector shift of each neighbouring sample point is added up by computing unit, obtain the vector shift of user current location and initial position, and then determine the coordinate information of user current location.
Then judging unit 104 judges that whether the vector shift of user current location and initial position is more than predetermined threshold value, if then sending the first signal to main control unit, does not otherwise send the first signal to main control unit.In the present embodiment, main control unit positioning unit in a dormant state time, also can control self enter resting state, thus saving power consumption further.After main control unit receives the first signal, will wake up from resting state, and after receiving the secondary signal that judging unit sends, wake positioning unit in a dormant state up；Described positioning unit is used for reorientating user current location, and obtains the coordinate information of user current location.Or, described main control unit is additionally operable to after being waken up receive the secondary signal that judging unit sends, and sends information.Described information can include information of voice prompt, text prompt information etc..
As in figure 2 it is shown, the initial position co-ordinates at user place that A0 point positions for positioning unit, the vector shift between A0 point and B0 point is sized to the size of predetermined threshold value；With A0 point for the center of circle, A0 point is sized to the preset range that circle is User Activity of radius to the vector shift between B0 point, and the B0 point that is easy to get is the critical point of this preset range；A1 point and A2 point are intermediate samples point.When user movement to A1 position, vector shift is sized to the A0 point distance to A1 point, due to the size less than predetermined threshold value, thus judging unit will not wake up main control unit, and main control unit is without waking positioning unit up, main control unit and positioning unit are still in resting state, and A0 coordinate can be added to the vector shift size of A1 point by user with A0 point, namely can determine that the coordinate of current A1 point.During point outside user movement to preset range, main control unit receives the first signal and is waken up, and then receives the secondary signal that judging unit sends, wakes positioning unit up.User current location is reorientated by positioning unit, confirms the coordinate of current location, it is ensured that the accuracy of location.Then current location is again as the center of circle (i.e. initial position) of new preset range, when the motion vector displacement of user is again above new preset range (sampling optimization that sampling unit samples is outside new preset range), positioning unit is again waken up by main control unit and reorientates, so repeatedly.Due to main control unit and positioning unit in preset range all in resting state, the coordinate position of user carries out cumulative according to the vector shift of each neighbouring sample point and obtains, thus being greatly saved user's power consumption of smart machine when positioning.
