Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
The embodiment of vehicle-mounted time synchronized service system
Fig. 1 shows the structure of the embodiment of vehicle-mounted time synchronized service system of the present invention.See also Fig. 1, the system of present embodiment comprises: the full-time on-line system of time synchronized client 10, vehicle 20, time server 30.
Communication relation between these devices: time synchronized client 10 is set up real-time communication with vehicle-mounted full-time on-line system 20 and is connected, and time server 30 is set up communication with vehicle-mounted full-time on-line system 20 and is connected.
The operation logic of the system of present embodiment is following.
Time synchronized client 10 will with throw to the time server 30 in high in the clouds of the network event that the full-time on-line system 20 of vehicle connects.
Time synchronized client 10 receives user's time synchronized request; And be transmitted to time server 30 through the full-time on-line system 20 of vehicle, when time server 30 receives the time synchronized request of time synchronized client 10 temporal information is synchronized to time synchronized client 10.This is the method for synchronization that receives user's request.
Time synchronized client 10 is every spontaneous to time server 30 transmitting time synchronization request at a distance from setting cycle.This is the method for synchronization of the spontaneous completion of client.
The refined structure of the full-time on-line system 20 of vehicle is as shown in Figure 2, comprises time synchronized client 10, load-balancing device 201, a plurality of Connection Service device 202, network event transmitter 203, signal repeater 204, metamessage server 205, message recipient 206, authorization control device 207.
Communication annexation between these equipment is: time synchronized client 10 is set up data communication through load-balancing device 201 with Connection Service device 202 and is connected; Network event transmitter 203 is set up data communication with Connection Service device 202 and is connected; Authorization control device 207 is set up data communication with Connection Service device 202 and is connected; Signal repeater 204 is set up data communication with Connection Service device 202 and is connected; Message recipient 206 and metamessage server 205 and Connection Service device 202 are set up data communication respectively and are connected, and set up data communication between metamessage server 205 and the Connection Service device 202 and connect.
It below is the operation logic of each device in the full-time on-line system 20 of vehicle of present embodiment.
Load-balancing device 201 is assigned to the strategy that the communication of time synchronized client 10 connects according to load balancing on many Connection Service devices, to realize the cluster of Connection Service device.Time synchronized client 10 keeps and being connected of Connection Service device 202 through the mode of sending heartbeat packet.
Connection Service device 202 is realized multiple function: receive from time synchronized client 10 and distribute the connection request of coming through load-balancing device 201; When connect accomplishing, the information of each connection (is comprised IP and the port of equipment or user's unique identification, client, the IP and the port of Connection Service device; The inside end slogan of Connection Service device and hyphen etc.) be registered to metamessage server 205; When connecting disconnection, nullify the connection on the metamessage server 205; The packet from time synchronized client 10 that receives is sent to corresponding external application servers (being instant communication server 210 and synchronization server 211 in the present embodiment) through signal repeater 204, and the information that receives from message recipient pushes and is pushed to time corresponding sync client 10.In addition, Connection Service device 202 also carries out resource release through the connection pool on the management server to overtime connection.
Authorization control device 207 is set up data communication with outside single logging-on server 208 and is connected, and whether proving time sync client 10 is legal.
Metamessage server 204 provides the registration and unregistration service of connection, the annexation between record Connection Service device 202 and the information synchronization client 10, and the connection pool on the management server provides the query function to link information.Metamessage server 204 can be connected in which process of which Connection Service device according to the identification number query time sync client 10 of device clients and the relevant information of hyphen.
There are two kinds of technological means to handle the processing procedure of checking and metamessage server 205 records.First kind of technological means is after authorization control device 207 verifies out that time synchronized client 10 is legal, again the annexation between record Connection Service device 202 and the time synchronized client 10 in metamessage server 205.Second kind of technological means is the annexation that in metamessage server 205, writes down earlier between Connection Service device 202 and the time synchronized client 10; Whether legal through 207 proving time of authorization control device sync client 10 again, verifying out that time synchronized client 10 deletes the record of correspondence in the metamessage server 205 after illegal again.
Network event transmitter 203 sends to outside network event with the network event between time synchronized client 10 and the Connection Service device 202 and subscribes to device 30.
The packets of information that signal repeater 204 time of reception sync client 10 are sent through Connection Service device 202; Application service under the identifying information bag is transmitted to packets of information the application server (being instant communication server 210 and synchronization server 211 in the present embodiment) of corresponding outside.
Message recipient 206 receives the packets of information of outside application server (being instant communication server 210 and synchronization server 211 in the present embodiment); Through the corresponding Connection Service device 202 of metamessage server 205 inquiries, send to time corresponding sync client 10 by Connection Service device 202 again.
When time sync client 10 with after the current Connection Service device that is connected 202 breaks off, time synchronized client 10 can connect once more and goes up the cloud platform, need connect the Connection Service device 202 that the last time connects again this moment with time synchronized client 10.Present embodiment can adopt two kinds of technological means to reach this purpose, and first kind of technological means is that the strategy through design on load-balancing device 201 makes time synchronized client 10 still set up the communication connection with the preceding Connection Service device 202 that once is connected when time synchronized client 10 connects once more.Second kind of technological means is when time synchronized client 10 connects once more, to pass through the time synchronized client 10 of record on the inquiry metamessage server 205 and the corresponding relation between the Connection Service device 202, makes time synchronized client 10 still set up communication with the preceding Connection Service device 202 that once is connected and connects.
