Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The present invention is directed to low side devices of the prior art and can't join the deficiency of Jini network, a kind of intelligent domestic system integrated approach based on Jini is proposed, introduced agency's notion, give limited household equipment (low side devices) design of these disposal abilities and memory headroom separately act on behalf of body, replace them to finish the basic agreement of Jini by acting on behalf of body, thereby make these equipment can be in the Jini network from discoverys, interpolation certainly, self-configuring, self diagnosis, safeguard certainly, and then realize controlling other equipment or by functions such as other Equipment Control.
Realize that the present invention at first needs to set up intelligent domestic system, it comprises parasitic device, acts on behalf of body, proxy module, act on behalf of body host, Jini network; Parasitic device is the limited equipment that can not directly join the Jini network of disposal ability and memory headroom; Acting on behalf of body is to be used for representing parasitic device to join a Java object of Jini network; Proxy module is to provide the module of software and hardware operation platform for acting on behalf of body; Acting on behalf of the body host is the parasitic place of acting on behalf of body, provides resource and running environment for acting on behalf of body, in acting on behalf of the whole life of body it is managed.
Proxy module can be designed to an independent agent equipment, also it can be embedded in the family in the miscellaneous equipment, and it has served as the function served as bridge between parasitic device and the Jini network, interconnects with adopting various privately owned connections between the equipment.Proxy module is realized by moving of object, for the design of these parasitic device separately act on behalf of body, form with JAR (Java archive file) is stored in the parasitic device, in the time of operation jar file is loaded on the proxy module that Jini running environment can be provided and finishes.
The implementation procedure that parasitic device joins the Jini network can be divided into three steps:
1. parasitic device with act on behalf of the body host and find mutually.Parasitic device wants to join the Jini network, at first must and acting on behalf of the body host finds mutually, acting on behalf of the body host has adopted certain privately owned connection to guarantee the two in case interconnection just can be found mutually with parasitic device, general employing parasitic device multicast or broadcasting are to acting on behalf of the method that the body host asks, if parasitic device and the privately owned this technology of not supporting that is connected, also can finish in privately owned interconnection detection parasitic device, can adopt different discovery techniques specific to different privately owned connections by acting on behalf of the body host.Fig. 1 is the initial condition schematic diagram of proxy module, proxy module has served as the bridge between parasitic device and the Jini network as can be seen, act on behalf of body host inside and contain enough host's resources, so that the body of acting on behalf of to later loading manages, it is privately owned the connection and act on behalf of what adopt between body host and the parasitic device.
2. act on behalf of body host loading and act on behalf of body.In case parasitic device and act on behalf of the body host and find mutually after, act on behalf of the body of acting on behalf of that the body host just retrieved and obtained this parasitic device, this process makes loading act on behalf of body.The method that body is acted on behalf of in loading both can be by having acted on behalf of the body host from parasitic device download agent body, also can initiatively will act on behalf of body by parasitic device and upload to and act on behalf of the body host.Act on behalf of the body host and obtain acting on behalf of after the body of parasitic device, act on behalf of the body host and just can activate and act on behalf of body, at this moment, act on behalf of body and just can use host's resource of acting on behalf of the body host, these host's resources may be JVM or Jini class etc.At this moment, act on behalf of body just can represent parasitic device carry out various tasks (such as, can accept the control or the control miscellaneous equipment etc. of miscellaneous equipment by the agency who acts on behalf of body).Certainly, parasitic device may itself not acted on behalf of body, acting on behalf of the body host so also can be from the body of acting on behalf of of retrieving this parasitic device somewhere beyond this equipment, such as, act on behalf of the body host and to the manufacturer website of this equipment, go to download according to manufacturer, the model of equipment.When retrieving this and act on behalf of body, will download it get off, with pending.Fig. 2 acts on behalf of the body host to load the schematic diagram act on behalf of body, acts on behalf of body as can be seen and has been loaded on and acts on behalf of among the body host.
3. body is acted on behalf of in operation, represents parasitic device to execute the task.After acting on behalf of body and being loaded, act on behalf of body and just can utilize and act on behalf of the various software and hardware resources that the body host is provided, be equivalent to this and act on behalf of body and replaced this parasitic device to join the Jini network.At this moment, this acts on behalf of body just can carry out various tasks for the parasitic device of its representative, as shown in Figure 3, acts on behalf of body and enjoys host's resource and replace parasitic device to join in the Jini network, with pending various tasks.Act on behalf of body and act on behalf of the body host all will monitor parasitic device whether also with act on behalf of the state of activation that the body host keeps privately owned interconnection, this is determining to act on behalf of the life cycle of body.If act on behalf of and do not have available communication channel between body and the parasitic device, might be in parasitic device, act on behalf of body, privately owned connection and abnormal conditions have taken place for some place of acting on behalf of among the body host, at this moment, all are distributed to whole host's resources of acting on behalf of body and are just regained.
