Description
Technical field
The present invention relates to of the realization of unified plug and play (UpnP, Universal Plug and Play) technology at DPF, in particular, a kind of DPF and its implementation based on unified plug and play protocol.
Background technology
Existing network technical development till now, can make our surfing on the net, receiving and dispatching mail, hear the sound that a distant place sends, search for interested content, download software, request program, instant chat ... the better function picture of realization is many, but, people's desire has no limits, the people that lives in ease and comfort also thinks more to live in ease and comfort, also have many targets not reach: for example, how just can make us on network, as at ordinary times with remote controller, the operating air conditioner device, electric fan, kitchen appliance, or the electric equipment of network far-end? how to utilize the computer resource on the network, make this " remote control " have more intellectuality? even, a series of relevant controls are write in the script, so that the control flow that customization oneself is liked ... realize suchlike effect, will be the application technologies that great demand is arranged.If realize controlling housed device with UPnP, will bring great convenience to our life and a lot of new experience by network.
For example:
1, the user is before coming off duty, or on the way home, just can open the air conditioner and the cooking apparatus of family earlier, waits to enter the door, and the environment that temperature is pleasant--the meal in the kitchen has also been carried out at once.The process of cooking in the height of room temperature and the kitchen all is to carry out according to " script " program that designs in advance, and is absolute reliable.
If 2, the music fever person that improves grade of one of user, very tight to the environmental requirement of listoning music certainly: audio amplifier position height, volume, light light and shade, curtain are pulled on all and are worthy of careful study.Manually control with good, inconvenient after all.You should use UPnP, and all can be done for you.Can also be with acoustics volume, the lamplight brightness of your custom, height of audio amplifier or the like, think with you that best parameter is write and carry out in the script, can all take this as the standard later on.If you have the special listening room of oneself, as long as you open the door of listening room, above-mentioned environment will set at once.End, relieved by all means having left, the UPnP system understands oneself and closes sound equipment, extinguishes electric light, draws the curtain together.
3, the user but fails to lay down the child of family at heart in office.Use UPnP,, set up being connected of good and network at home as long as camera is installed.In office, enable the WEBTV of desktop computer, behind the connected network, can monitor the every act and every move that child stays at home immediately.
By adopting the UPnP agreement, just can realize above-mentioned these operations at present.Because UPnP is an agreement, the use of UPnP can be crossed over various operating system platforms, and developing application does not have the limitation of development language yet, can work in various forms of network configurations; And only based on the present network facilities, after adding the UPnP agreement, both need not add new facility, also need not set up network medium again, just can come into operation.
Briefly, the UPnP agreement has following characteristic:
1, is applied environment with the network, do not consider the computer in " isolated island ".
2, based on TCP/IP and whole Internet.The UPnP agreement is " neutrality " like this, does not depend on any operating system or application program, does not use specific api function, is not subjected to the limitation of programming language; It can seamlessly insert legacy network.
3, equipment can dynamically enter in the network, obtains the IP address subsequently, intelligently " study " or search the operation that oneself should carry out and the information of service; Whether " perception " other equipment exists and their effect and current state.All these all can be finished automatically.
4, each equipment all can read one's own, particular state and parameter; Finish the response signal that to send " operation is finished " after the control operation.If failure then should be sent the control failure signal.
The final purpose of UPnP agreement is to set up an available device model, has following principal character.
1, UPnP is the frame system that a multi-layer protocol constitutes, and each layer is again the basis on adjacent upper strata all based on adjacent lower floor simultaneously.Till reaching application layer.Nethermost is exactly IP and TCP, two-layer altogether, the IP address of being responsible for equipment.
2, three layers is transportation protocol layers such as HTTP, HTTPU, HTTPMU.What transmit is after content is all passed through encapsulation, to leave in the specific XML file.Corresponding SSDP, GENA, SOAP refer to the data format that is kept in the XML file.After this one deck, solved the IP address and the information of the transmission problem of UPnP equipment.
3, the 4th layer is the definition of UPnP equipment system, only is abstract, a public device model.Any UPnP equipment all must use this one deck.
4, layer 5 is the device definition layer of each Professional Committee of UPnP forum, in this forum, different electric equipments are by different Professional Committee's definition, for example: the TV committee only is responsible for define grid television equipment part, the air conditioner committee and only is responsible for define grid air-conditioning equipment part ... the rest may be inferred.All dissimilar equipment all is defined by a special framework or template, uses in the time of for apparatus for establishing.Enter after this one deck clear and definite purposes that equipment is designated.Certainly, the standard that these all must adherence to standardization.Currently, UPnP can support most equipment: from computer, computer peripheral equipment, and mobile device and domestic consumer class of electronic devices or the like, along with popularizing of this individual system, to have more producer and admit this standard, final, may develop is the industry standard of generally acknowledging.
5, the superiors, just application layer is decided through consultation adopted part by the UPnP equipment manufacturing.The information of this one deck is come " filling " by device fabrication manufacturer, and that this part generally has is that equipment vendors provide, to the bottom code of Equipment Control and operation, and title sequence number, manufacturer's information or the like.
Complete UPnP service system is made of jointly the network of supporting UPnP and the equipment that meets the UPnP standard.Whole system is made of equipment, service and steering needle three parts.
Equipment is meant the equipment that meets the UPnP standard.UPnP equipment can be regarded one as and comprise service and nested " container " of conventional equipment.For example, the VCR of a UPnP (video tape recorder) equipment can comprise magnetic tape transport service, tuning service and clock service.In other words, the equipment under the UPnP can not only be interpreted as the equipment on the hardware meaning, and should comprise service function.
Setting, service and embedding equipment that different types of UPnP equipment is different with association.Belong to the equipment of different purposes as printer and VCR, service just can not be defined as.
Equipment is carried out the control procedure of user's request, can be divided into very little one by one stage or unit, and each unit just is called a service.Each service externally all show as concrete behavior and pattern, and behavior and pattern can be described with state and variate-value.As long as can describe, just handled easily in the computer the inside with numerical value.For example, imitate a clock, it has only a mode of operation: this pattern is exactly simulation and shows the current time.And the behavior of a clock has two kinds: the time is set, for example carries out time operation; Obtain the time, be used for the demonstration time.
The miscellaneous equipment service is also described and is defined with such thinking, and an equipment also can be defined a plurality of services.No matter be the definition information of equipment and the descriptor of service, all be kept in the XML file, this file also is the part that the UPnP agreement constitutes.When equipment was set up and use service, the XML file can carry out related with them.
Also have very crucial " state table " in the XML file, state table can be further divided into " service state table " and " state-event table ".In the overall process of whole UPnP equipment operation, state table is carried throughout, when equipment state changes, when parameter variation or state refresh for example take place, just reflects in " state table " immediately.When the behavior request that receives the time of setting, just carry out request as Control Server immediately, carry out to the time operation, and provide response, simultaneously the relevant data in the update mode table.Correspondingly, event server is responsible for announcing that to the interested equipment of part as to this state that is taken place changes.For example, after an event of fire took place, event server was just issued this incident to fire-alarm, caused the alarm action to produce alarm signal.
In the UPnP network, the control that user's requesting service is carried out realizes that by steering needle steering needle at first is the effector of other equipment of control of having the ability, and also will have the ability of " discovery " controlled target in network.After finding controlled target, steering needle should:
1. obtain the descriptor of equipment and obtain associated service list;
2. obtain the description of related service;
3. call the control service behavior;
4. determine the incident " source " of service, whenever, as long as service state changes, event server can send an event information to steering needle immediately.
The various information of mentioning from above all are kept in the XML file, the information of different purposes, form difference.Assurance can each takes what he needs, can not obscure.
Specify the complete course of work of UPnP below.
UPnP provides communication function between steering needle and controlled device.And network medium, ICP/IP protocol, HTTP only provide basic connection and IP address assignment.Entire work process need be handled the content of six aspects, and promptly address assignment, discovering device, the description to equipment, Equipment Control, device events, equipment are expressed.
The address is the basic condition of whole UPnP system works, and each equipment all should be the client of DHCP (Dynamic Host Configuration Protocol, DHCP).After device first and network connect, utilize the DHCP service, make equipment obtain an IP address.This IP address can be the appointment of DHCP system, also can certainly, have the ability oneself to select the equipment of IP address by choice of equipment, and must be smart machine; This just so-called " automatically " IP address.
If run into the IP Address requests outside the local DHCP range of management, also need to solve the address allocation problem of " friendly equipment ", this problem is solved by name server usually.
Discovering device can be divided into two kinds of situations, and a kind of is after control request is arranged, and searches to have or not corresponding available devices in current network; Another kind of situation is a certain equipment access network, obtains after the IP address, just begins oneself to have entered network to network " broadcasting ", promptly seeks control request.
The description of equipment is used to state which type of equipment this equipment is, for example title, manufacturer, serial number or the like.After just beginning " discovery " equipment, steering needle to " understanding " of this equipment also seldom need find the description document of this equipment according to ULR, reads more descriptor from these files.The wide range of descriptor generally all is that the manufacturer by equipment provides.Main description project has: ULR of the WEB of the MODE name of control and mode number, Equipment Serial Number, manufacturer's title, manufacturer or the like.These generally all leave in the specific XML file.
Steering needle finds after the device description, can " refinement " go out the operation that will carry out and learn all services from describe; Concerning each UPnP equipment, these descriptions must be very definite, very detailed, parameter of may include order or behavior tabulation, service response information in the description, using or the like.For each behavior of service, also with descriptor: mainly be the variable, data type of a variable during whole service is carried out, available span and the feature of incident.
Control certain equipment, a control of the necessary transmission earlier of steering needle behavior request requires equipment to begin service, and then presses the ULR transmission control corresponding message of equipment, and control messages is exactly the information that is placed on those SOAP forms in the XML file.At last, service can be returned response message, and the service pointed out is success or failure.
In the whole time that service is carried out, change has taken place as long as the state of variation or pattern has taken place variate-value, just produced an incident, the content of the above-mentioned list of thing of mentioning will be revised by system.Thereupon, event server is broadcasted incident to whole network.On the other hand, steering needle also can be in advance to event server reservation event information, and assurance sends the interested incident of this steering needle timely and accurately.
Broadcasting or the reservation incident, transmission all be event message, event message is also placed in the XML file, the form of use is GENA.
Preparation---initialization procedure before equipment is devoted oneself to work also is an incident, and the various information that initialization needs also transmit with event message.The content that comprises mainly is: variable initial value, initial condition of pattern or the like.
As long as obtained the ULR of equipment, just can obtain the ULR that this equipment is expressed the page, this expression can be included on user's the local browser then.This part also comprises the interface with user session, and carries out the processing of session with the user.Whole UPnP system is collaborative work under the commander of " nervous centralis ".Roughly situation is as follows for it:
Every possess the IP address the equipment IP address that all must directly use network, but some equipment may not have the ability of direct use network ip address, for example, the control of light switch comes to this, this is non-IP device; Non-IP device comes and the steering needle exchange message by bridge (UPnP Bridge).
Directly use having of IP address: steering needle (can on pocket computer and remote equipment, send control), local device, for example VCR and clock; And bridge.Non-IP device has the equipment (as lamp controlling switch etc.) of so-called light equipment (as temperature controller) and non-UPnP.
Above-mentioned introduction belongs to hardware aspect, puts off until some time later the software as the control soul below.
In the superincumbent narration, repeatedly mention with the XML file and deposit the information that needs, because no matter be steering needle or device service, all need a lot of information, have and read, have to spread out of, the UPnP agreement is arranged these and is all left in the specific Files XML.The information that purposes is different, the form difference in the XML file.So relevant XML file is the soul of control service.
