Carefully be described as follows: (1) user is stepped under internet environment using application program for mobile terminal DMS.apk input user information
Record;(2) the information of the database of Cloud Server is inputted user by http protocol log-on message and Cloud Server carries out school
It tests, confirms whether the user information is effective;(3) user information inspection result is returned to application program for mobile terminal by Cloud Server
DMS.apk;(4) whether application program for mobile terminal DMS.apk checks this time to log in and succeed;(5) application program for mobile terminal is used
DMS.apk opens the camera of mobile device, and scanning Multimedia Program contains equipment ID number, equipment what multimedia interface generated
The two dimensional code of type and timestamp information obtains the information in the two dimensional code;(6) application program for mobile terminal DMS.apk will pass through
The two-dimensional barcode information that multimedia interface obtains is sent to long-range Cloud Server by HTTP, requests Cloud Server by the multimedia
Apparatus bound is to active user;(7) after cloud server end program DmsECSServer receives bind request, inspection requirements quilt
Whether the multimedia equipment of binding is to register in Cloud Server;(8) when requiring inspection of the bound equipment by Cloud Server
Cha Hou, Cloud Server bind equipment ID number, device type, timestamp information and the user name, and the information is lasting
Change into the database of Cloud Server, then notifies application program for mobile terminal DMS.apk;(9) application program DMS.apk is received
After the message of the binding success of Cloud Server, the control authority of present multimedia equipment can be obtained.Since then, user and multimedia
Apparatus bound operation is completed, and active user can log in any client and control current multimedia equipment.
As shown in figure 3, detailed by the specific control flow that server end (Cloud Server) authenticates multimedia equipment
It is carefully described as follows: after (1) multimedia equipment is connected to the network where server end, by HTTP to server end (cloud service
Device) connection request is sent, request data is raw when including the equipment ID number, device type and the equipment internal registration of multimedia equipment
At device certificate;(2) after server end (Cloud Server) receives the request, equipment ID number and device type are obtained, and pass through
The digital certificate of server internal, which calculates, generates a Token;(3) server end (Cloud Server) is calculated using itself
Token, the equipment ID number received and device type regenerate device certificate;(4) server end (Cloud Server) compares from setting
Whether the device certificate that the device certificate that standby termination receives is calculated with oneself is consistent;(5) if by verifying, by the equipment
It is added to current online equipment list.Since then, equipment verification process is completed, and after authenticating step, client can lead to
Cross server control multimedia equipment.
As shown in figure 4, client carries out multimedia equipment by server end (Cloud Server and LAN server)
Detailed description are as follows for the specific control flow of control: client-side program (DMS.exe, DMS.apk, WEB) passes through HTTP to service
Device end (Cloud Server and LAN server) sends the instruction for obtaining multimedia equipment list;(2) server end (Cloud Server
And LAN server) obtain database in by certification online multimedia equipment list and not online multimedia set
Standby list, and list of devices is returned into client;It (3), can be to server end (cloud clothes after client obtains list of devices
It is engaged in device and LAN server) send control instruction to equipment, setting comprising the multimedia equipment that is directed in the control instruction
Standby ID number, device type and the Token generated using the instruction;(4) server end (Cloud Server and LAN server) is right
The instruction received regenerate Token, and compares the Token received, if the two is equal, sends an instruction to pair
The multimedia equipment answered;(5) after multimedia equipment receives the instruction of server end (Cloud Server and LAN server) transfer
It executes, and implementing result is returned into server end, server end is returned again to client.Since then, client passes through server
The process of control multimedia equipment terminates.
As shown in Figure 5,6, detailed process client direct-connected multimedia equipment and multimedia equipment is controlled, to scheme
Detailed description are as follows for 5: (1) client (end PC and mobile terminal) is (mobile by wired mode (end PC) or wireless mode
Terminal, direct-connected AP- wireless access points) it is connected to multimedia equipment, and (end PC passes through by client application
DMS.exe, mobile terminal pass through DMS.apk) connection request is sent to multimedia equipment;(2) multimedia equipment application program
After DmsApp receives request instruction, which is verified;(3) multimedia equipment application program DmsApp is to client
Application program sending device information packet includes equipment ID number, device type and device certificate in the data packet;(4) client
After receiving the request data that multimedia equipment is sent, the request data and equipment are verified;(5) after being verified,
Client can by it is wired or wirelessly give equipment send control instruction;(6) multimedia equipment is transmitted across client
The instruction come is verified, and is executed after being verified, and implementing result is returned to client application.Since then, client
Direct-connected multimedia equipment and the process completion that multimedia equipment is controlled.
This programme is provided from client application, server-side application program again to the pipe of multimedia equipment end application program
Reason system, client supports the end PC, mobile terminal and WEB application, and the end PC application program and mobile terminal application program are supported extensively
