The structure of conventional home network is described below in conjunction with Fig. 1.As shown in Figure 1, domestic network system need be provided with an Equipment Control center, the TCP/IP related protocol can be adopted in all information household appliances equipment and Equipment Control center, 1394 buses or wireless transmission protocol are connected to home network, are provided for the communication layers and the physical layer that transmit and receive data between the terminal equipment of various connections.Yet, also can use other communication protocol that communication is provided.Like this, a network generally can comprise a plurality of according to predefined communication protocol exchange and the equipment that physical layer is connected that passes through that transmits data.Each information household appliances equipment comprises the interface data that is used to be provided with through networking command and control information home appliance interface (HTML for example, XML, JAVA, JAVASCRIPT, GIF, JPEG, graphic file, or any other is used for the form of required purpose).In certain embodiments, each information household appliances equipment comprises one or more HTML(Hypertext Markup Language) pages or leaves that are used for order and control information home appliance.Home network can adopt browser technology, presents the HTML page or leaf according to Internet Standard, so as for the user provide a plurality of be used for order and control various information household appliances equipment graphical user interface (GUI).
In addition, can intercom mutually between the information household appliances equipment, and needn't understand the detail of other communication layers.When at different information household appliances communication between devices, home network can use the combination of different communication layer.
General flow below with reference to transmission information and control procedure between Fig. 2 descriptive information home appliance and the Equipment Control center.As shown in Figure 2, information household appliances equipment includes the information description file of self.The information household appliances equipment that is connected on the network sends the information description file of information household appliances equipment self by interface in network, with the attribute of representing self and the function service that can provide.The information description file that the interface at Equipment Control center sends by the network receiving information home appliance, with the information description file storage of various information household appliances equipment in the storage device at Equipment Control center.Store the chained list of information household appliances equipment in the storage device at Equipment Control center, set up threaded file according to the facility information in the information description file of the information household appliances equipment that receives, more new user interface.Can implementor name is associated with information household appliances equipment, and the memory device name be set up threaded file in chained list by after detecting the information household appliances equipment that is connected on the network.Also can this implementor name be stored in the chained list, and convert implementor name to device button and set up threaded file by retrieval facility name in the information description file of slave unit.
When the user calls information household appliances equipment in the network, the Equipment Control center utilizes the threaded file of this equipment of setting up to send the message of calling this equipment to network by interface, the information household appliances equipment that is connected in the network passes through the message call of interface receiving equipment control centre, it is responded, return and call the result, carry out the command adapted thereto that the user sends, send the status message of this equipment simultaneously to the Equipment Control center.After the Equipment Control center receives the status message of information household appliances equipment, upgrade the message of this equipment of storing in the chained list.After this, the Equipment Control center is controlled and is managed according to the more new user interface of canned data home appliance in the storage device.
In home network environment, the Equipment Control center comes from the information transmission of information household appliances equipment and control centre to the control and management of equipment.Had only when the information household appliances device responds service call, when returning this equipment running status information simultaneously, one calling just of effective equipment finished.And when certain information household appliances equipment becomes an invalid equipment, will fail to the service call of equipment in the Equipment Control center.
Therefore, the Equipment Control center needs a cover can verify the mechanism of the validity of the information household appliances equipment of the chained list of storing in its storage device in listed, and deletion can not provide the invalid equipment of device service function from chained list.
Because information household appliances equipment will send the information description file of self in network when access network, with function and the self attributes of representing that this information household appliances equipment can provide.Therefore, consideration increases the service for checking credentials in its function that provides service, so that the ruuning situation of information household appliances equipment can be in time understood at the Equipment Control center, with and with the connection status of network, the chained list that upgrades in time and store, the information household appliances equipment that deletion has exitted network, thus the misoperation of user prevented to invalid equipment, and saved system resource.
According to the present invention, provide two kinds of checking approach.A kind of is when the function service that an information household appliances equipment provides is wished to call in the Equipment Control center, should call the service for checking credentials of this information household appliances equipment earlier, but detect the running status of this equipment.When the Equipment Control center obtains the information of authentication failed, with calling of this subfunction service of cancellation, this equipment is considered as invalid equipment, and deletes this facility information description document in the chained list of the memory device stores of slave unit control centre, at this this verification mode is called and calls checking.In addition, chained list at the information household appliances equipment of Equipment Control central service is comprising the home appliance that all add networks, but considers have many equipment seldom to use in these home appliances at all, and utilance is extremely low, safeguard that they need spend resource, they also very easily become invalid equipment simultaneously.Therefore consider to use least recently used principle, by the utilization rate of weighing equipment the equipment that seldom uses is carried out validity check, carry out statistical comparison by the utilization rate of equipment simultaneously, the information household appliances equipment that utilization rate is lower than preset threshold is deleted from chained list, reduce the plant maintenance burden at Equipment Control center, this verification mode is called delay time verification at this.
For above-mentioned double verification, its essence is according to the utilization rate of information household appliances equipment and respectively equipment is handled.If the utilization rate of equipment is higher, then only need it is called checking.On the other hand,, then to consider earlier it is regularly carried out delay time verification,, it be called checking as the delay time verification success if the utilization rate of equipment is lower.
When the utilization rate of computing information home appliance, need consider three factors: the access times of the on-line time of equipment, the service time of equipment and equipment.The on-line time of equipment is long more, and its service time is short more, and access times show that then this equipment seldom uses more after a little while.Can be with on-line time service time of equipment than last equipment, the utilization rate that the equipment that obtains once calls, the access times of utilization rate and this equipment are multiplied each other obtains the utilization rate of this equipment again.Utilization rate decision by investigating equipment is verified the priority of processing to equipment, and the device authentication priority that utilization rate is low more is high more, promptly preferentially it is verified processing.
The utilization rate formula of computing information home appliance is as follows:
The content stores of the authorization information of expression information household appliances equipment is at information household appliances equipment, together sends on the network with the information description file of information household appliances equipment, and received by the Equipment Control center.
In order in Equipment Control, to carry out validation verification in the heart, consider that adopting the binary tree principle is information household appliances equipment equilibrium establishment binary tree structure at the Equipment Control center.Utilization rate with information household appliances equipment is determined the position of equipment in balanced binary tree as weights.The equipment that utilization rate is low is those equipment that least often use, and preferentially it is carried out validation verification.An information household appliances equipment includes the various information relevant with this equipment as a node on this device tree in the node, wherein also comprise this authorization information.
The character of general balanced binary tree is: when this binary tree during for empty tree, if its left subtree be a sky, then on the left subtree value of all nodes all less than its value of root node; If its right subtree is not empty, then on the right subtree value of all nodes all greater than its value of root node; Its left and right sides subtree is that the absolute value of difference of the degree of depth of balanced binary tree and its left subtree and right subtree is no more than 1 too.According to this character, under the situation that has the identical equipment of several checking priority, can only there be an equipment to join in the equipment binary tree structure, obvious like this is inappropriate.Therefore, consider the second in the balanced binary tree character is adjusted, if promptly its right subtree be a sky, then on the right subtree value of all nodes all more than or equal to its value of root node.The equipment that has identical checking priority like this will add device tree as the node on the right subtree.
Fig. 3 is the structural representation that according to the balanced binary tree of information household appliances equipment of the present invention.Circle representative information home appliance among the figure, the utilization rate of this equipment of numeral in the circle.The circle that has shade represents to verify the priority height, need carry out the equipment delay time verification and call the equipment of checking it, and other capacity utilization is higher, only needs it is called checking.By the service equipment binary tree, the Equipment Control center can needing obtain the equipment of delay time verification by the query facility tree, and these equipment are just on the left subtree of device tree, so only need the left subtree of query facility just can be easy to obtain the least information of common equipment, they are carried out delay time verification.
Include database in the Equipment Control in the heart, storing equipment operation condition information in the equipment running status table of safeguarding in the database, wherein comprise on-line time, access times, service time of statistics, the equipment of the utilization rate of equipment etc.Each equipment withdraws from, the statistics of the utilization rate that all can update the equipment in the Equipment Control center, and according to calculating the position of adjustment equipment in binary tree.
Below with reference to the flow chart of Fig. 4 explanation according to information household appliances equipment validation verification of the present invention.At first, at step S411, information household appliances equipment access network also sends the information description file of information household appliances equipment self in network by interface, comprising the service for checking credentials, with the attribute of representing self and the function service and the authorization information that can provide, wherein authorization information is to point to the Equipment Control center to return the information of calling this equipment success or failure.At step S412, these information description file and services for checking credentials that the interface at Equipment Control center sends by the network receiving information home appliance, this equipment is found at the Equipment Control center in the equipment running status table, according to this equipment running status table information of information updating of the content in this facility information description document and the service for checking credentials.At step S413,, revise the weights of this device node and the structure of the equipment of adjustment binary tree based on the utilization rate of calculating according to the utilization rate of the equipment running status table computing information home appliance that upgrades.At step S414, set up threaded file at the Equipment Control center according to the facility information in the information description file of the information household appliances equipment that receives and the weights of amended device node, more new user interface.
As user during in the service of the function of step S415 invocation facility, the service for checking credentials of this equipment is at first called at the Equipment Control center, if the service for checking credentials is represented successfully to call this equipment, the function corresponding with customer requirements then carried out by sending instruction to this equipment in the Equipment Control center; If call service for checking credentials failure, then show the information of malloc failure malloc, and this equipment of deletion in the Running Status Table of slave unit and the chained list, to repeat to call this equipment after avoiding.At step S416, according at step S415 to the service for checking credentials with call the result and the operating position of use, recomputate the utilization rate of this equipment, and it existed in the equipment running status table, revise the weights of device node, adjust the structure of equipment binary tree.On the other hand.Information household appliances equipment is carried out the desired function of user according to the instruction at Equipment Control center, at step S417 to Equipment Control center Returning equipment operational factor, upgrade Running Status Table, and determine whether the structure of needs adjustment equipment binary tree and the nodal information of the equipment of modification according to lastest imformation.At step S418, user user's display interface is upgraded at the Equipment Control center.In addition, by the setting-up time section, can be according to the statistics of the capacity utilization in the equipment running status table and the utilization rate of equipment, adjust the structure of device storage tree, will certain hour in the cycle utilization rate be lower than the equipment of threshold value as invalid equipment, this equipment of deletion in slave unit Running Status Table and the chained list, and revise the structure that device node is adjusted the equipment binary tree.If S415 calls authentication failed in step, then in the tabulation of step S419 slave unit, delete this equipment.
In sum, by validation verification to home appliance, the invalid equipment of storing in the sweep equipment control centre not only, the harmful effect of having avoided invalid equipment in the household electrical appliances editing equipment management, the user to be caused, saved simultaneously the resource at Equipment Control center effectively, made in the home network environment more rationally efficient the unified management mechanism of home appliance.
