Detailed description of the invention
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the flow chart of message method one embodiment of the present invention.As it is shown in figure 1, this message method comprises the following steps:
Step S101: receive the geography information of controlled terminal；
In step S101, preferably receiving the geographic messages being received from controlled terminal by server and forwarding, this geography information is the latitude and longitude coordinates of the actually located position of controlled terminal.
Step S102: display is marked with the electronic chart that identify labelling corresponding with geography information；
In step s 102, after receiving the actual latitude and longitude coordinates of controlled terminal, to showing identification labelling at latitude and longitude coordinates in electronic chart, in order to the understanding controlled terminal location that user is clear and intuitive, concrete electronic chart can be as shown in Figure 2.
Step S103: receive the target area that user delimit on electronic chart；
In step s 103, target area is the delimitation that user is carried out on the electronic chart that screen shows, this target area is screen pixels region, and therefore received is the screen pixels coordinate of target area.
The present embodiment selected objective target region is rectangular area, and in other embodiments of the invention, target area can also be capable of the region of shape of screen pixels Coordinate Conversion, such as border circular areas for other.
Step S104: determine the controlled terminal being positioned at target area according to geography information and target area；
In step S104, preferably the screen pixels Coordinate Conversion received is become the actual latitude and longitude coordinates in electronic chart, then the actual latitude and longitude coordinates of the geography information (i.e. latitude and longitude coordinates residing for controlled terminal) of controlled terminal with target area is compared, and then determine the controlled terminal being positioned at target area, and make list.Such as, when target area is rectangular area, two, this target area screen pixels coordinate to angle point can be obtained, and these two the screen pixels Coordinate Conversion to angle point are become the actual latitude and longitude coordinates in electronic chart, and judge that the latitude and longitude coordinates residing for controlled terminal is whether between the two actual latitude and longitude coordinates to angle point, if being in therebetween, being positioned at above-mentioned target area, if being not in therebetween, being then not located between above-mentioned target area.When target area is border circular areas, the center of circle of this border circular areas can be become the actual latitude and longitude coordinates in electronic chart with the screen pixels coordinate transformation of radius, and by judging less than above-mentioned radius, whether the distance between the latitude and longitude coordinates residing for controlled terminal and the center of circle judges whether controlled terminal is in above-mentioned border circular areas.Certainly, those skilled in the art by the geography information of controlled terminal is converted into screen pixels coordinate, and can compare with the screen pixels coordinate of target area and realize above-mentioned functions completely.
Step S105: send message to the controlled terminal being positioned at target area.
In step S105, the present invention is sent to server by the list of the controlled terminal being positioned at target area that will determine and message, then is forwarded this message by server controlled terminal in list.
In the present embodiment, the controlled terminal being preferably pointed in target area selectively sends message.After receiving the message, automatically prompting user is so that user checks and accepts the preferred controlled terminal of the present embodiment in time.Server can also carry out need to forwarding the list of the controlled terminal of message and forwarding the changing of geography information of the storage of message time, controlled terminal to store and the data management of electronic chart.
Fig. 3 is the structural representation of mobile terminal one embodiment of the present invention.As it is shown on figure 3, mobile terminal 200 includes: receive device 210, display device 220, input equipment 230, processing means 240 and dispensing device 250.
In the present invention, receiving device 210 and be used for receiving the geography information of controlled terminal 400, this geography information is the geographic messages that server 300 receives from controlled terminal 400 and forwards.Processing means 240 controls display device 220 display according to this geography information and is marked with the electronic chart that identify labelling corresponding with geography information.Input equipment 230 is for receiving the target area that user delimit on electronic chart, processing means 240 is positioned at the controlled terminal 400 of target area according to geography information and target area for determining, dispensing device 250 is for sending message to the controlled terminal 400 being positioned at target area.
Wherein, geography information is the latitude and longitude coordinates of the actually located position of controlled terminal 400.The present embodiment selected objective target region is rectangular area, and target area can also be capable of the region of shape of screen pixels Coordinate Conversion for other in other embodiments of the invention.Electronic chart in the present invention is the electronic chart downloaded from network by wireless communication or hardware interface.
The operation principle of the mobile terminal 200 of the present invention is: when user needs to send message to the controlled terminal 400 of target area, server 300, by setting up communication connection with controlled terminal 400, obtains the geographic messages of controlled terminal 400 and is sent to mobile terminal 200.The device 210 that receives of mobile terminal 200 receives the geographic messages being received from controlled terminal 400 by server 300 and forwarding, and in electronic chart, at the latitude and longitude coordinates of correspondence, mark identification labelling according to this geography information, display device 220 display has the electronic chart identifying labelling, in order to user is in clear and intuitive understanding controlled terminal 400 location.User delimit target area as desired by input equipment 230, and now input equipment 230 receives the screen pixels coordinate of this target area.Processing means 240 is connected with input equipment 230, screen pixels Coordinate Conversion is become the actual latitude and longitude coordinates in electronic chart, and the actual latitude and longitude coordinates of the geography information of controlled terminal 400 with target area is compared, determine and be positioned at the controlled terminal 400 of target area and make list, and preferably shown by display device 220.After user is obtained list by display device 220, by the message that input equipment 230 input is to be sent, dispensing device 250 will be located in the list of the controlled terminal 400 in target area and message sends to server 300, message, and then the transmission of completion message is forwarded again by the server 300 controlled terminal 400 in list.
In the present embodiment, can be that heart beating is connected between mobile terminal 200 with server 300, server 300 and controlled terminal 400, it is also possible to the radio communication network for alternate manner connects.
The preferred controlled terminal of the present embodiment 400 after receiving the message, is sent a message by server 300 to mobile terminal 200 and sends successfully prompting, in order to user obtains message in time and sends process.
In sum, the present invention be by delimiting target area in electronic chart, and combining geographic information confirms to be positioned at the controlled terminal of this target area, and then completes to send the message of controlled terminal in target area, thus improves message transmitting efficiency.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
