Abstract

The utility model relates to a portable personal GPS positioning terminal. A movement detecting device is added on the positioning terminal, and can detect that whether the current terminal is in moving state (for example, carried by pedestrians) or in static state for long time (for example, placed on a table) in real time, therefore, the GPS terminal can determine the working state thereof according to the moving state or static state thereof. For example, when the terminal is static for long time, a GPS module opens every half an hour, thus reducing the power consumption of the GPS module. When the terminal is in moving state, the opening interval of the GPS module can be adjusted by combining the recent moving condition of the terminal, so as to reduce the opening times of the GPS module as possible, further effectively reduce the power consumption, simultaneously avoid the condition that the position can not be achieved due to long distance; and the length interval of the positioning points can not be pulled to be too long to influence the actual positioning effect.

Description

Portable, personal GPS locating terminal

Technical field:

The utility model relates to Portable, personal GPS locating terminal, particularly terminal low-power consumption, the Portable, personal GPS locating terminal that stand-by time is long.

Background technology

Existing Portable, personal GPS locating terminal, owing to be subjected to the influence of the higher power dissipation of the volume restrictions of locating terminal and GPS module, about the stand-by time just for one day.

On the other hand, GPS need could effectively locate at outdoor opening.So in the more weak place of GPS, as under indoor, the big tree, in the car etc., terminal can't be carried out normal effectively location, and as individual locating terminal, be in time of outdoor open ground and few for a long time, cause existing bigger blind area, location.The existence of blind area, location makes the GPS locating terminal cold location of may having to again after leaving the blind area, cold location required time is more much longer than warm location, further causes high power consumption, and then causes stand-by time short.

The problem that prior art solves power saving adopts external power supply or timely charging modes more, and this makes troubles for use of terminal, influences the portability of locating terminal.

The utility model content

At the problems referred to above that the Portable, personal locating terminal exists, the utility model provides a kind of method of intelligent power saving, does not influence the practical position effect with the service time that prolongs terminal.

The utility model realizes that the scheme of above-mentioned purpose is:

Owing to added motion detection apparatus on locating terminal, motion detection apparatus can be real-time, and to detect current terminal be to be kept in motion (going along with as the pedestrian) or to be in long-time stationary state (as placing on the table).Like this, the GPS terminal just can decide the duty of GPS terminal according to its motion or static state.Such as can be long-time when static in terminal, the GPS module be opened once only per half an hour, reduces the power consumption of GPS module.When terminal is moved, but the motion conditions that integrated terminal is nearest, adjust the interval that the GPS module is opened, reduce opening number of times and can effectively reducing power consumption of GPS module as far as possible, do not produce simultaneously the fixed not upper situation of long distance, the length of anchor point can not drawn oversizely at interval and be influenced the actual location effect yet.

Embodiment

The basic design of present embodiment is to add a motion detection apparatus (being motion sensor in this example) on locating terminal, and pick-up unit can be real-time, and to detect current terminal be to be kept in motion (going along with as the pedestrian) or to be in long-time stationary state (as placing on the table).Long-time when static when terminal, the GPS module is opened once only per half an hour, reduces the power consumption of GPS module.When terminal is moved, also can not open the GPS module, but the nearest motion conditions of integrated terminal is adjusted the interval that the GPS module is opened always, when nearest motion is very fast, increase the frequency of opening the GPS module, otherwise reduce the frequency of opening the GPS module.Like this, when terminal user's walking, because speed is lower, it is also very low that the GPS module is opened frequency, reduces opening number of times and can effectively reducing power consumption of GPS module.When the terminal user was sitting on the automobile, the GPS module can strengthen the number of times of opening of GPS module according to the travelling speed of automobile, so also was unlikely to produce the fixed not upper situation of long distance, and the length of anchor point can not drawn oversizely at interval and be influenced the actual location effect.

In order to describe above-mentioned mechanism in detail, we are divided into following several state with the terminal motion:

State	Explanation
State	Explanation	Static	Inductor surpasses 120 seconds and does not sense motion, then enters into stationary state.For example Tracker places on the table, is placed on static Che Li etc.
Low-speed motion	Movement velocity＜5km/h, as in indoor activity, walking.	Static
Low-speed motion	Movement velocity＜5km/h, as in indoor activity, walking.	The middling speed motion	5km/h＜movement velocity＜20km/h as by bike, is run.
High-speed motion	Moving speed＞20km/h, as ride in an automobile train.	The middling speed motion	5km/h＜movement velocity＜20km/h as by bike, is run.

Migration pattern between each motion state:

Under each state of terminal, the time such as the following table of opening the GPS module and reporting:

The Tracker state

Data report

Explanation

Static	All states except that low electricity	Static	30 minutes	10 minutes	Under the static situation,, just can open GPS when needs during to Surveillance center's reported data.When static, only needed 30 minutes to obtain gps data one time, connected a Surveillance center, and reported nearest available point in per 10 minutes.
						Low-speed motion	Normally	Low-speed motion	100 seconds	5 minutes	Under the lower-speed state, opened one time the GPS module in per 100 seconds.＜138 meters of consecutive point distances
The middling speed motion	Normally	The middling speed motion	50 seconds	5 minutes	Under the middling speed state, opened one time the GPS module in per 50 seconds.＜280 meters of 70 meters＜consecutive point distances
						High-speed motion	Normally	High-speed motion	25 seconds	5 minutes	Under the fast state, opened one time the GPS module in per 25 seconds.140 meters＜consecutive point distance
Charging	Charging	All states	25 seconds or 10 minutes	25 seconds or 10 minutes	When being in charged state, Tracker keeps long with Surveillance center and is connected, and need not disconnect.When motion state when not being static, obtained a gps data every 25 seconds and report the center immediately.When motion state when being static, obtained gps data in then per 10 minutes and report immediately.
						Low	Low	All states	30 minutes	30 minutes	After entering low electricity condition, the interval that data report is lengthened to 30 minutes once, only just opens worker GPS module when reported data.

Present embodiment also adds a GSM locating module on locating terminal, when terminal is in the GPS blind area and can't effectively locatees, terminal can obtain the information of the GSM base station at current place, by the information acquisition position of GSM base station, the position of GSM base station and coverage all are kept in the database well early stage as calculated again.Though there is certain error the position that obtains by the method, but can know the approximate range of terminal, in conjunction with nearest effective GPS anchor point, can satisfy individual locating accuracy requirement fully, avoid the GPS module to enter again cold positioning states and increase power consumption because of can not find original position.

In order to accelerate the cold positioning time of GPS module, open the GPS module at every turn after, GPS restarts the location, but obtain the approximate location at current place from base station information, and this information offered the GPS module, accelerate the positioning time of GPS module, thereby further reduce power consumption.

Because intermittence is opened the GPS module, Overall Power Consumption obviously descends, the service time of lengthening terminal.Use the GSM base station information to obtain the current position of terminal, effectively reduced the blind area, location, in the experience that has strengthened the user, further reduced power consumption.
