Abstract
The utility model discloses a dynamic position data upload system, comprising a locating and tracking device, a motion sensing chip, and a CPU. The motion sensing chip supports acceleration detection and is installed in the locating and tracking device. The I2C interface of the motion sensing chip is connected with the CPU in the locating and tracking device. The motion sensing chip acquires acceleration of each direction of a target object in real time, and the acceleration is transmitted to the CPU. The CPU is installed in the locating and tracking device, and adjusts upload frequency of locating data of the motion sensing chip in real time according to received acceleration data of the target object of the motion sensing chip. The system achieves an objective of saving flow and power consumption, and solves problems that tracking and locating interval is too long or power consumption of a terminal is too large, and data flow is large.
Description
Technical field
The utility model relates to location tracking technique, particularly a kind of dynamic position data upload system based on acceleration motion sensor.
Background technology
In tracking field, location, system needs to be uploaded onto the server in the position of target object at any time.The general mode that adopts timing to upload in the processing that current positioning and tracking device is uploaded in locator data, this mode can achieve the goal, but there are several problems: if uplink time interval is too short, power consumption and data traffic are larger, cause stand-by time short high with use cost; If uplink time interval is long, can not well reflect again the motion details of target object, especially in fast moving.
Utility model content
For the problems referred to above, applicant, through Improvement, proposes a kind of dynamic position data upload system, and to solve, track and localization interval is long or power consumption of terminal is large, the problem that data traffic is large.
The technical solution of the utility model is as follows:
A kind of dynamic position data upload system, comprises positioning and tracking device, action induction chip and CPU; Described action induction chip is supported acceleration detection, is arranged in positioning and tracking device, and the I2C interface of described action induction chip is connected with the CPU in positioning and tracking device; The acceleration of described action induction chip Real-time Collection target object all directions, is transferred to described CPU; Described CPU is arranged in positioning and tracking device, according to the acceleration information of the target object of the action induction chip receiving, adjusts in real time the upload frequencies of the locator data of action induction chip.
Useful technique effect of the present utility model is:
The utility model has added action induction device in positioning and tracking device, the time interval of uploading by adjusting, reach the object of saving flow and power consumption, and solve that track and localization interval is long or power consumption of terminal is large, the problem that data traffic is large.
Advantage of the present utility model will provide in the description of embodiment part below, and part will become obviously from the following description, or recognize by practice of the present utility model.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the utility model adds the action induction chip of supporting acceleration detection in the positioning and tracking device of target object, and action induction chip is generally by its I
2c interface is connected with the CPU in positioning and tracking device, in real time the acceleration of target object all directions is transferred to CPU.CPU, according to the acceleration information of receiving, adjusts locator data upload frequencies in real time.
For the operation of target object, can be at horizontal X, horizontal Y, three Directional Decompositions of vertical Z.Because the processing of all directions is consistent, below just directions X wherein algorithm is described.Follow the tracks of for location, the resolution D of an expectation need to be set, numerical example is as can be 100 meters, 200 meters etc.
Hypothetical target object M is static, is spaced apart T=T0 at the uplink time of initial position, and the acceleration readings Ax of action induction chip is 0.After positioning and tracking device starts, first upload the current location of target object M to server.
If M remains static all the time within the T0 time, the next time interval T1 uploading need increase by 50% on upper basis once, until maximum time interval Tmax.Arrange maximum time interval Tmax order be to think terminal broken string for fear of system.
T1=T0+0.5*T0; By that analogy, Tn+1=Tn+0.5*Tn.
If Tn+1>Tmax, Tn+1=Tmax;
If within the T0 time, variation has occurred acceleration A x, according to acceleration A x and duration T 0, calculate the speed V of target object M in X-direction:
Vx=Ax*T0; By that analogy, Vx=Ax*Tn.
Two other direction can be processed equally, calculates Vy, Vz.In most of the cases, location is followed the tracks of and is only considered moving horizontally of target object, so the motion in the vertical direction of target object can be ignored.
Then synthetic motion stack:
Calculate next time interval Tn+1 with the resolution D expecting and the speed V of target object M.
Tn+1＝0.5*D/V
The calculating of above-mentioned speed is used absolute value, and this is that because no matter be forward direction speed or reverse speed, the impact that produces displacement for object of which movement is consistent.
By enforcement of the present utility model, for the object of operation, in conjunction with the built-in acceleration induction device of positioning and tracking device, the resolution that follow the tracks of the location effectively ensureing, for static object, the data of uploading that reduce to greatest extent, ensure stand-by time.
In sum, the utility model has solved stand-by time, and the problem of resolution is followed the tracks of in uploading data flow and guarantee.The utility model is implemented very convenient, as long as increase an acceleration action induction chip on the mainboard of former positioning and tracking device, this chip passes through I
2c interface is connected with base band.
For example, the utility model can be applied in the location tracking function of child mobile phone, on cell phone mainboard, add acceleration induction chip, can realize children in the upper ways for education, on bus by this chip, continuous location fast, at school time, mobile phone is placed in school bag, realize the location at maximum duration interval, meet the demand that ensures children's safety completely.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from spirit of the present utility model and design, within all should thinking and being included in protection domain of the present utility model.
