Description
Technical Field
The invention relates to the field of AllJoyn networks, in particular to a method and a device for sending and processing AllJoyn network messages.
Background
AllJoyn is an open source software project that provides a common communication framework for different electronic devices; AllJoyn is a P2P (PeerPeer-to-Peer) communication framework, where the two parties of communication are the service provider and the service consumer, respectively. In the communication mechanism of AllJoyn, a service provider and a service consumer communicate by implementing the same interface specification. The AllJoyn interface comprises three members of a method, an attribute and a signal, wherein the method is a function call, receives one or more input parameters, carries out corresponding processing, and returns one or more output parameters; the attribute is variable comprising read-only, write-only and read-write modes; the signal is asynchronous notification information, and the signal receiving party performs corresponding operation through a signal processing mechanism.
In addition, the AllJoyn provides an event-action mechanism, where the event is an interface signal including human readable words, the action is an interface method including human readable words, a user can set a trigger relationship between the event and the action through a user interface, and the rule engine stores the trigger relationship between the event and the action set by the user, and the rule engine needs to operate on a device stably connected to an AP (Access Point) for a long time as an application program.
The intelligent home system is often required to be applied in scene linkage, and a signal processing mechanism and an event-action mechanism in AllJoyn can provide technical feasibility for scene linkage.
However, the inventor finds that the prior art has the following defects when the invention is realized:
the event in the AllJoyn is a signal in the message format, only human readable words are added, and the event and the signal cannot be distinguished from each other in the message type, so that a signal processing mechanism can be triggered, and the collision of the AllJoyn network service can be caused. The concrete description is as follows:
in the use scenario of AllJoyn, a device manufacturer or developer listens to a certain signal according to a service provided by the own party, and once the signal occurs, performs a corresponding operation. However, the user may set the trigger relationship between the same event and action through the event-action mechanism of AllJoyn due to the unknown service to the device vendor or developer, which may result in the repeated execution of AllJoyn business, causing unpredictable effects.
Taking scene linkage as an example, the situation of service conflict that may occur in the current AllJoyn network is shown in fig. 1.
When the intelligent door is opened or closed, door opening and closing events can be sent out, and when the intelligent door sends the events, a signal processor in intelligent lamplight can monitor the events and trigger the operation of turning on or turning off the lamp;
the user sets an event sent by the intelligent door and an action executed by the intelligent light in the rule engine through an event-action mechanism in AllJoyn to carry out pairing;
when the intelligent door sends the door opening event, the signal processor in the intelligent lamplight monitors the door opening event, so that the lamp opening operation is triggered. This may result in repeated execution of the lighting-on operation, causing an all joyn network traffic conflict, as shown in fig. 1. Wherein the solid lines with arrows represent signal processing mechanisms and the dashed lines with arrows represent event-action mechanisms.
