Description
Technical field
The present invention relates to a kind of method that realization is controlled all UPNP equipment in the local area network (LAN) based on UPNP (Universal Plug and Play UPnP) agreement.
Background technology
China steps into the internet economy epoch just gradually at present, no matter is all to have obtained more general application in family or corporate lan.Along with information household appliances add network, outstanding all the more for the demand of shared device and shared network resource and service.Transparent access various network resource is very complicated task, realizes that information household appliances or equipment room can interconnect, and the purpose that reaches resource-sharing becomes the major subjects of existing network technical development.Can solve this type of problem preferably based on the UPNP agreement.
The UPNP agreement is the network application-level protocol on a kind of framework and the TCP/IP, in fact the application of UPNP agreement has expanded the notion of traditional stand-alone device and network system, at the interactive operation interfaces such as exchange that mutual discovery, interface statement and other information between the networking gear are provided under the prerequisite of " zero configuration ".
The configuration information of networking gear in the wireless network, the COS that can provide have very big-difference.Obtaining the information of every UPNP equipment in the network and can realize controlling all UPNP equipment by universal control devices, is the prerequisite that realizes network equipment information interaction and resource-sharing.Also be based on the technical development of UPNP protocol network, the project that must solve.
Summary of the invention
The objective of the invention is to develop the control program at network equipment control point by the method operations such as the automatic discovery of realization UPNP equipment and control appliance service for the UPNP equipment development provides a kind of universal control method.
Universal control method of the present invention is the input/output module by the control point program, call control point module and device management module and generate needed program, routine call various processing modules in control point are carried out corresponding operating, and general controls point program can be write by the developer.
Mainly comprise following control module in the described general controls point program, promptly facility information describing module, UPNP facility information list management module, UPNP protocol stack, UPNP control point module, device discovery event processing module, device events processing module, the predetermined timeout treatment of device service, equipment withdraw from event handling, equipment is finished control point control command event handling, general controls point XML parsing module, I module.
Described facility information describing module generate all UPNP equipment of description information, the file of the type and the parameter of service is provided, and carry out storage operation with regard to this class description file; Described descriptor file includes facility information file (UPNP Device), service information file (UPNP Service), service state variable information file (UPNP StateVariable), operation information file (UPNPAction), parameter information file (UPNP Argument).
Based on required running environment of UPNP control point module controls and control point, to the service transmit operation of UPNP equipment; When operation is finished when failure (or), return any result or mistake; Subscribe to (cancelling subscriptions) certain Service events, the query service status variate-value calls monitoring and control to UPNP equipment automatically.
When the device discovery event processing module when receiving the device discovery incident, the data that receive are resolved, according to the single equipment name of equipment, the invocation facility information module is inquired about; If this equipment in tabulation, is then changed the time spot of this facility information; Do not go out device description file URL if do not exist then according to the data parsing that receives, download equipment statement file, the call XML parsing module is resolved description document, obtains the essential information of equipment.
After the message that control point the UPNP equipment in the network of receiving is sent when withdrawing from, equipment is deleted from the facility information at control point.
When described equipment has been finished the control command of sending at the control point, send return results message to the control point; The control point receives the laggard line data of this message and resolves, and the invocation facility information management module is changed equipment corresponding apparatus information then, or carries out error message and handle.
When the control point when official hour is not received predetermined Service events information, carry out again predetermined; If still unsuccessful, think that then this equipment may be improper withdrawing from, and deletes this equipment from the list of devices at control point.If subscribe to successfully again, then obtain the information on services parameter in the change equipment behind the device numbering.
The described equipment self check processing module of exceeding the time limit, regularly improper the withdrawing from whether of the UPNP equipment in the checkout equipment network.
As mentioned above, the interconnect equipment universal control method based on the UPNP agreement of the present invention has following function and advantage:
1, finds all UPNP equipment in the network.After finding UPNP equipment, will retrieve the description of this equipment and obtain the tabulation of all services under this equipment;
2, can be scheduled to reception incident and change the state variable value of device service according to incident to device events service source;
3, according to the device service information in the list of devices in the general controls point, to device service transmit operation control messages;
4, show all devices tabulation, the details of display device.
