Equipment end and control end are subscriber is also publisher, and, equipment end is fixed prefix with itself No. SN and makees
Be the theme the message subscribed to and issue, and control end is fixed prefix using pay close attention to equipment No. SN and subscribes to as theme and disappearing of issuing
Breath；The theme that equipment end is subscribed to is the theme that control end is issued, and the theme that equipment end is issued is the theme that control end is subscribed to；
Proxy server is according to equipment end corresponding topic of subscription automatic push control command to corresponding equipment end；When setting
, to after proxy server, proxy server is according to this letter of topic of subscription automatic push of control end for standby end issued state change information
Cease corresponding control end；
When equipment end surprisingly goes offline, according to the unfulfilled wish of the deceased mechanism of MQTT agreement itself, control end can be from proxy server
Receive the message being previously set, control end can be offline by this Information check equipment end.
Further, when equipment end surprisingly goes offline, equipment end can by the heart beating with proxy server know oneself with
Server is disconnected connection.
Further, after equipment end connects upper proxy server, issue the message reached the standard grade with regard to equipment to agency
Server；After the equipment of concern connects upper proxy server, control end can receive a concern equipment from proxy server and send out
The message reached the standard grade with regard to equipment of cloth.
Further, the theme that control end is read surely is multiple, control end it can be found that and monitoring multiple equipment state.
Further, the theme that equipment end is read surely is multiple, and equipment end can be controlled by multiple control ends.
The invention has the beneficial effects as follows：Developer in using MQTT protocol procedures it is not necessary to agreement to MQTT and
Interface is understood in detail, saves the development time, improves development efficiency；Avoid using during conventional TCP/IP agreement communication

The problem being likely to occur；Avoid that equipment end bandwidth availability ratio is low, the high problem of power consumption.
Brief description
Fig. 1 is the schematic flow sheet of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, technical scheme is further elaborated.
As shown in figure 1, equipment end and control end are all connected to proxy server by MQTT in this example.Equipment end in this example
For intelligent appliance, it is using the SN of Fixed CP plus this equipment as the theme that will subscribe to and issue；Control end is then with fixation
Prefix adds No. SN of the equipment of needs concern as the theme subscribed to and issue.The theme that equipment end is subscribed to is that control end is issued
Theme, the theme that equipment end is issued is the theme that control end is subscribed to, and corresponds to two-by-two.So control end issues control instruction to agency
After server, proxy server will be according to equipment end corresponding topic of subscription automatic push control command to corresponding equipment
End；After equipment end issued state change information is to proxy server, server can push away automatically according to the topic of subscription of control end
Give this information to corresponding control end.
Equipment end can issue the message reached the standard grade with regard to equipment to server after connecting upper proxy server, works as control end
After server in connection, because control end have subscribed the theme of concern equipment server can disappearing of reaching the standard grade of automatic push equipment
Cease control end, such control end has been detected by equipment and has reached the standard grade, control end just can send control instruction.
When equipment end needs the correlation behavior sending equipment to control end, directly issue related status information to service
Device, server is according to this status information of theme automatic push subscribed to corresponding control end.Because multiple control ends can be ordered
Read identical theme, so multiple control end all can receive this status information.
When equipment end accident server disconnects, it is previously set according to " unfulfilled wish of the deceased " mechanism server push one of MQTT
