s600, clicking a communication list of the request terminal App or a nickname of a user presented on the electronic map, displaying detailed information of the user by the App, and when the App of the request terminal needs to communicate with other movable intelligent terminal devices in the address list, double clicking the communication list of the request terminal App or the nickname of an App account presented on the electronic map to carry out instant call.
Specifically, the data structure of the registration information includes a mobile phone number, a communication group tag, a feature code, and a nickname.
Specifically, the data structure of the device status information includes: APP account information, positioning information, search radius, custom state and other parameters known by the sensor.
Specifically, the movable intelligent terminal device is connected with a background server through a wireless communication module, a positioning sensor is used for positioning the movable intelligent terminal device, an App uploads positioning information of the movable intelligent terminal device to the background server through the wireless communication module, the background server is used for scanning other device information within a certain radius range around the movable intelligent terminal device according to the positioning information of the movable intelligent terminal device serving as a request end and generating a communication list to be pushed to the movable intelligent terminal device serving as the request end, the App presents all the device information in the communication list on an electronic map interface of the movable intelligent terminal device at the request end according to the positioning information, and supports the request end to carry out instant communication with other devices in the generated communication list, so that the movable intelligent terminal device within a certain distance range can automatically generate a communication list, and the purpose of rapid communication is realized.
Specifically, the computing algorithm principle of the background server is as follows: as shown in fig. 8, the distance between any two coordinate points of the sphere is calculated;
The distance formula between any two points on the spherical surface is as follows:
and (3) setting the longitude and latitude coordinates of the point A as (x, y), the longitude and latitude coordinates of the point B as (u, v), and r as the radius of the sphere.
And converting the longitude and latitude coordinates into radian coordinates, wherein the radian L is theta pi/180. Where θ is the angle value.
jA＝xπ/180，wA＝yπ/180
jB＝uπ/180，wB＝vπ/180
The longitude and latitude coordinates of the A point are converted into coordinates (jA, wA) through radian
B point longitude and latitude coordinate (jB, wB) converted by radian
AB＝rcos-1[cos(wA)cos(wB)cos(jB-jA)+sin(wA)sin(wB)]
O (U) is knownO，VO) And the radius r of the sphere is obtained by calculating the distance from any point to the O:
assuming that the radian coordinates of any point of the spherical surface are (X, Y), the distance l from the O:
l＝rcos-1[cos(Y)cos(Vo)cos(UO-X)+sin(Y)sin(VO)](1 type)
When the distance from any point to the O is less than R, the communication group member belongs to; otherwise, the communication group member is not.
Specifically, the device information of the online user is updated to the background server in real time through the communication link established between the device and the background server. The background calculates the range of the geographic position of the device requesting the communication list within the distance M by acquiring the information of each device, searches other devices within the range, and generates and issues the communication list of the device requesting the communication list. The background needs to calculate a communication list for each request terminal device and issues the communication list to the request terminal device for presentation. Since the correspondence list is generated based on the distance between the devices, this process requires that the correspondence list where each device is located be refreshed at intervals in order to include devices that come within M distance range into its communication group or to exclude devices that are beyond M distance range from its communication group.
And calculating a device list in the distance range of M, mainly calculating the distance between the two devices. Currently, the respective longitude and latitude data of two devices are known, and the distance between the two devices can be obtained by solving the shortest distance between two coordinate points of a spherical surface.
Let the longitude and latitude coordinates of point A be (x, y), and the longitude and latitude coordinates of point B be (u, v)
And converting the longitude and latitude coordinates into radian coordinates, wherein the radian L is theta pi/180. Where θ is the angle value.
The longitude and latitude coordinates of the A point are converted into coordinates (jA, wA) through radian
B point longitude and latitude coordinate (jB, wB) converted by radian
l＝rcos-1[cos(Y)cos(Vo)cos(UO-X)+sin(Y)sin(VO)]
Specifically, the flow of the communication architecture established between the devices is shown in fig. 7, and when the device a needs to call another device (for example, the device H), the steps are as follows:
the device A initiates an instant communication request to the background server, and submits the registration account information of the device A and the registration account information of the called device to the background server. The background server multicasts a message that lets the target device H initiate a link communication with the background, in the example because the device H is in a mobile network, Shanghai City, or some area. And the background initiates a multicast message to the channel where the device H is located. Although all devices in the same group receive the same message, the other devices automatically ignore the message because the target device of the communication is device H. After receiving the message issued by the background server, the device H initiates a request for establishing link communication with the background. Thus, the device a establishes a communication link with the background, and the device H establishes a communication link with the background server. All messages are transferred through the background server and then forwarded to the target device, so that the instant two-way communication function is completed. The reason why the direct communication link between the device a and the device H is not established is that the network link is unstable when they are moving, resulting in poor quality of direct communication between the device a and the device H.
Specifically, fig. 3 is a flow of the client App acquiring the address book and the related parameters.
Specifically, as shown in fig. 4, the process of the background server searching for the communication group list of the request end is as follows:
the background server is initialized, analyzes the state parameters submitted by the client, calculates the search area according to formula 1, traverses the current positioning information of other client apps and counts out a communication list, judges whether the positioning information of the client apps in the communication list is filled according to the parameter B, and issues the communication list and the equipment state information to the request end apps.
Specifically, as shown in fig. 6, the client presents a temporary communication group client information list (taking an Android map SDK provided by the Baidu map open platform as an example):
registering a Baidu account, applying for becoming a Baidu developer, acquiring a service key (ak), initializing a map, selecting a map display type, map display contents and a map operation type, reading and analyzing longitude and latitude coordinate information of each client in a communication list, calling a batch adding interface, marking the coordinate information analyzed in the last step on the map, covering a nickname, a feature code and a state parameter as icons on a marking point, and adding a call-back function of an operation event of clicking the marking point. And the detailed preview of the target client information is realized by clicking, and the instant messaging function is called by double clicking.
The client electronic map module: and integrating the application services of the existing electronic map providers, such as Android map SDKs provided by hundreds of degrees. The functions of map display type, map display content, map operation, point and line drawing and surface monitoring, annotation event monitoring and the like are mainly needed. The method supports the user to select certain map display types such as a standard map, a satellite map, a 3-dimensional map and the like; selecting one or more map display contents such as 'roads', 'buildings', 'scales', 'display user positions', and the like; selecting one or more "map operations" such as "zoom", "scroll", etc.; drawing the marking points of the communication equipment list on the electronic map by using the operation of drawing points, lines and surfaces; and capturing an event of clicking a mark point of the electronic map by using the monitoring mark event, clicking the expansion information of the presentation equipment, and double clicking to start the instant voice call.
According to the technical scheme, the address list can be automatically generated by the movable intelligent terminal equipment within a certain distance range through the positioning information and the feature code of the movable intelligent terminal equipment, so that the purpose of rapid communication is achieved, the communication list can be dynamically generated and is dynamically added and deleted along with the change of the distance, and the problems that the operation process is inflexible, private communication account numbers are revealed, and the communication timeliness is poor in the conventional instant communication mode at present are effectively solved.
