Description
Technical field
The present invention relates to the method and system demonstrating position of hiring a car during network is hired a car at passenger's end equipment, refer more particularly to demonstrate to hire a car at passenger's end equipment and run the method and system of animation.
Background technology
Hire a car in system at network, due to the utilization of network so that supply and demand can be carried out more pellucidly between passenger and driver mutual, the coupling of demand and transport power thus realizing hiring a car rapidly, efficiently utilize transport capacity resource, and reduce the energy resource consumption that taxi sky is sailed, save the waiting time of passenger. Thus, network hires a car system and relevant technology is obtained for quick development.
Hiring a car in system at above-mentioned network, be carry out on network owing to ordering car, when passenger and driver reach acknowledgement of consignment purpose, taxi is generally also distance with passenger, and therefore, passenger needs to wait that taxi arrives acknowledgement of consignment place. Period, in order to passenger can be best understood from the position of taxi, it is necessary to the change of Dynamic Announce taxi position on passenger's end equipment.
Hiring a car in system at existing network, passenger's client generally adopts to the mode of system poll taxi position of hiring a car to obtain taxi position, so can produce peak value congestion phenomenon, and the pressure of server is bigger. Further, in existing passenger's client, it is common that directly display the taxi position received, cause that the animation of taxi position shows not smooth, have jumping phenomena, affect the experience of user.
Thus, hire a car in system at current network, being badly in need of technological means solves the problems referred to above, needs to reduce the pressure that taxi position poll is produced by passenger's end equipment at server end on the one hand, and still further aspect is it is required that the display of animation is smooth.

Accompanying drawing explanation
Fig. 1 illustrates according to the structural representation demonstrating the system running animation of hiring a car at passenger's end equipment of the present invention.
Fig. 2 illustrates the step according to the embodiment demonstrating the method running animation of hiring a car at passenger's end equipment of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, with specific embodiment, the method and system demonstrating operation animation of hiring a car at passenger's end equipment of the present invention is described.
With reference to Fig. 1, according to one embodiment of present invention, system of the present invention relates to driver's end equipment 1, passenger's end equipment 2 and taxi position tracking server 3.
Wherein, driver's end equipment 1 is connected to taxi position tracking server 3 by network, and described network can be 3G network or 4G network, or the combination of other wireless network and wireless network and cable network.
Further, driver's end equipment 1 utilizes the position of its GPS module timing acquisition taxi and separated in time, and the positional information of taxi uploads to taxi position tracking server 3. Described interval time can be fixing, it is also possible to is as speed and adjusts.
In the present invention, driver's end equipment 1 is connected to taxi position tracking server 3 by network, to obtain the positional information of taxi. Described network can be 3G network or 4G network, or the combination of other wireless network and wireless network and cable network.
But, it being different from existing technical scheme, passenger's end equipment 2 is not by the positional information that poll taxi position tracking server 3 obtains taxi. This is because in the polling case, polling time interval is not by server controls, and the peak value easily producing to produce owing to passenger's end equipment 2 concentrates on certain time point initiation poll blocks up.
In the present invention, passenger's end equipment 2 subscribes to the positional information of the taxi being its service to taxi position tracking server 3, is subscribing to after successfully, and taxi position tracking server 3 regularly sends out, to passenger's end equipment 2, the positional information hired a car. In this implementation, server can adjust the transmission interval of positional information, and control at different time points by being sent by the positional information of different taxis, it is possible to sent with comparatively non-uniform manner by numerous positional informationes, thus the peak value produced in polling mode is avoided to block up.
After passenger's end equipment 2 have received the positional information of this taxi, it is necessary to demonstrate the change in location hired a car on electronic chart. The taxi positional information received due to passenger's end equipment 2 is discrete, if directly drawn on map according to the taxi positional information received, can produce picture discontinuous, and the use sense reducing user is subject to.
In order to solve the problems referred to above, in the present invention, passenger's end equipment can draw out the change of taxi position on electronic chart by each frame time interval, thus forming continuous animation.
Specifically, as passenger's end equipment 2 receives the tracing point of two drivers of two A, B from taxi position tracking server 3, so passenger's end equipment 2h can use third party's instrument, such as Baidu's map path planning, calculate the vehicle running path between two points of A, B, running time T, and sub-point A1, A2, A3, the A4 between two points ..., described path is divided into n section by this little point.
Afterwards, according to running time T and the hop count n that is divided into can two, company of solving put between running time T '=T/n;
Distance d between two son points can calculate in the following manner:
D=R*arcos [cos (Y1) * cos (Y2) * cos (X1-X2)+sin (Y1) * sin (Y2)],
Wherein, R is earth radius, and (X1, Y1) is the latitude and longitude coordinates of one of them sub-point, and (X2, Y2) is the latitude and longitude coordinates of another one point.
So, the travel speed between the two point can be expressed as: d '=d/T '.
In order to demonstrate the continuous motion hired a car on passenger's end equipment 2, it is necessary to calculating at interval of a frame, taxi is the distance of movement on map:
D=d '/Z/E, wherein E is scale, and Z is the frame number of refreshing per second.
Owing to being shown that the distance travelled on map every a frame (usually 1/24th seconds) taxi on passenger's end equipment 2, thus animation can be very smooth, thus the use sense improving user is subject to.
From the description of the invention above it can be seen that the present invention proposes a kind of method demonstrating operation animation of hiring a car at passenger's end equipment, with reference to Fig. 2, the method comprises the steps:
Step S001: driver's end equipment regularly reports the position of taxi to taxi position tracking server;
Step S002: passenger's end equipment subscribes to the position of the taxi being its service to taxi position tracking server;
Step S003: tracking server timing in taxi position sends the positional information of ordered taxi to passenger's end equipment;
Step S004: passenger's end equipment draws out the change of taxi position on electronic chart by each frame time interval.
Above already in connection with specific embodiment, and invention has been described with reference to accompanying drawing, but it is to be understood that, above-mentioned being embodied as is merely illustrative, is not intended that limiting the scope of the invention. Protection scope of the present invention is defined in the claims, and for technical scheme in claim make for amendment known in those skilled in the art, replacement and the combination of equivalence both fall within protection scope of the present invention.
