Description
Technical field
The present invention relates to smart home communication technical field, more particularly to a kind of message route cascaded based on MQTT multilayers
Method.
Background technology
Intelligent domestic gateway household appliances equipment can be connected by wired mode, wireless mode with it after by one
Unified interface is communicated with external network, and core roles are served as in smart home.But smart home scheme is deposited at present
In many deficiencies, general household internal only disposes a gateway, and the hardware interface that single gateway can be provided is limited, radio area
Domain scope is limited.It is multiple although physical distance and the not enough defect of hardware resource can be made up using the structure of multiple gateway
Connection and management between gateway are a great problems, so less be used.
There are many host-host protocols, wherein MQTT in current Internet of Things（Message Queuing Telemetry
Transport, message queue remote measurement transmission）To be developed by IBM Corporation, operation with TCP/IP on, based on message push, can
Lean on, steadily and surely, the agreement increased income, all had a clear superiority in terms of versatility, scalability, compatibility, power consumption and flow.But
There are following two problems in the network service for being currently based on MQTT agreements：Opened up because MQTT communications are more using hub-and-spoke network
Flutter, in traditional MQTT remote controls, multiple intelligent domestic gateways in family can be each via internet and intelligent family
The MQTT Broker for occupying service platform are attached communication, so for one family, and multiple gateways externally there is
The interface of multiple communications, platform is inconvenient to the multiple gateway managements of the same family, also to multiple gateway managements of multiple families
Inconvenience.Another problem is that, when household internal has multiple gateways, the gateways that user needs access different go to control not same district
Home appliance in domain.
Deficiency for current smart home scheme and the characteristics of MQTT protocol communications, the present invention proposes one kind and is based on
The message route method of MQTT multilayers cascade, improves the hub-and-spoke network topology of MQTT agreements, supports the gateway of multilayer cascade
Topology, using the smart home scheme of multiple gateway, realizes the multilayer cascade network between multiple gateway and carries out message route.
The content of the invention
It is an object of the invention to provide the message route method cascaded based on MQTT multilayers, the concentration of MQTT agreements is improved
Hub-and-spoke network topology, supports the gateway topology of multilayer cascade, supports connection networking and the message route of multiple gateway, solves current intelligence
Can household multiple gateway connection, communication and problem of management, and support in family according to custom rule by home appliance divide in
Different zones carry out safe and efficient Intranet control and small range management.
The purpose of the present invention is realized at least through one of following technical scheme.
A kind of message route method cascaded based on MQTT multilayers, including the multiple gateway networking based on MQTT, are route descending
It is up with routeing；
It is described that new gateway is added in legacy network based on MQTT multiple gateway networkings, new household electrical appliances are added in new gateway and are set
Standby, new gateway is connected to form the network topology structure of the multilayer cascade based on MQTT with other gateways；
The descending message sent by MQTT control ends that refers to of the route is routed to home appliance, and it is based on MQTT to route descending
Subordinate's routing rule of gateway is searched in the network of multilayer cascade, and forwards the messages to subordinate's gateway；
The up feedback message for referring to home appliance of route is routed to MQTT control ends, and the feedback including home appliance disappears
Breath is routed to all MQTT control ends and the feedback message of home appliance is routed to one of MQTT control ends.
Further, described method comprises the following steps：
Step 1: the multiple gateway networking based on MQTT.
Step 2: progress route is descending on the basis of based on MQTT multiple gateway networkings, by disappearing that MQTT control ends are sent
Breath is routed to home appliance.
Step 3: carrying out routeing up, the feedback message road of home appliance on the basis of based on MQTT multiple gateway networkings
By to MQTT control ends.
The multiple gateway networking based on MQTT comprises the steps in above-mentioned steps one：
（1）, gateways and starting when first inquire about local data base with the presence or absence of the UID of itself（Unique Identifier, the overall situation is only
One mark）.If being not present, UID is generated according to Snowflake algorithms, UID is used to identify gateway, the automatic topic of subscription of gateway
“/UID/#”（MQTT theme forms, oblique line（/）It is at all levels in a subject tree for separating, it provides a layer
The theme space of secondary structure.Numerical chracter（#）I.e. multi-level asterisk wildcard, for matching the arbitrary levels in a theme.“/
UID/# " is represented in " all themes under/UID/ " levels）.
（2）, then inquire about local data base, user configures the IP of the upper level routing node of the node by web page
Address.
（3）And then UID gateways are attached with upper level gateway UID0.Obtain higher level's gateway routing rule " .../
UID0/#”（Ellipsis " ... " refers to higher level's gateway and there may be the gateway higher than itself level, routing rule " .../
UID0/# " refer to can be routed to theme level for " ... all themes of/UID0/ " below）, update higher level in local routing table
The routing rule of gateway for " .../UID0/# ", the current routing rule of itself for " .../UID0/UID/# ".
（4）, upper level gateway receive UID gateways connection after, in the subordinate's gateway routing rule of itself add one
“.../UID/#”。
（5）, UID gateways and starting equipment discovery procedure, by search and information matches home appliance SID（System
Identification, systematic identification code）With the UID of itself, the globally unique of home appliance is used as using UID/SID form
Identify (USID), while gateway records " SID " and routing rule in the list of devices of itself.
（6）, UID gateways USID is reported into upper level gateway, higher level's gateway records " UID/ in the list of devices of itself
SID " and routing rule.
（7）, previous action is performed per one-level gateway recurrence, untill USID is reported to smart home service platform.
It is preferred that, the step（5）In, gateway records " SID " in the list of devices of itself and routing rule is specifically grasped
Make as follows：
Because the home appliance that current gateway searches SID is connected directly on gateway, therefore routing rule fills in gateway oneself
UID, and suffix filled on which hardware interface that the equipment is connected to gateway device, such as serial ports UART1, then remembered in list of devices
Record " SID ", routing rule " UID/UART0 ".
It is preferred that, the step（6）In, USID is reported upper level gateway by UID gateways, and higher level's gateway is set itself
Record " UID/SID " and routing rule concrete operations are as follows in standby list：
UID gateways search routing table in higher level's gateway routing rule for " .../UID0/ ", routing rule is used as issuing subject
Prefix.Such as gateway makes an announcement message, theme be " .../UID0/DEVINFO_NOTIFY ", content is USID；It is designated
UID0 higher level's gateway give tacit consent to automatic topic of subscription for " .../UID0/# " message, just can receive theme prefix for " .../
UID0/ " all message related to itself.The higher level's gateway for being designated UID0 is received after USID in itself original equipment
Addition record " SID " in list, routing rule is subordinate's gateway " UID ".
Progress route is descending on the basis of based on MQTT multiple gateway networkings in above-mentioned steps two, is sent by MQTT control ends
Message be routed to home appliance including following small steps：
（1）, by step one constitute multilayer cascade network close structure in, any one gateway is received from MQTT control ends
During message, the controlled device in message is first extracted.
（2）, then inquire about local device list.
（3）If, controlled device be not present in local device list, report upper level gateway, be finally reported to service
Platform, service platform abandons this message.
（4）If, controlled device be present in local device list, query routing rule, directly transmit the message to route
Subordinate's gateway in rule, if next stage is itself, home appliance is transmitted the message to by corresponding transparent transmission module.
It is preferred that, the step（1）（2）In, UID0 gateways receive MQTT control message themes be " .../UID0/
CONTROL/SID ", first extracts controlled device SID, then inquires about local device list and there is SID, routing rule is subordinate's net
Close " UID ", UID0 is UID in modification theme, forwards the message to subordinate's gateway.
Progress route is up on the basis of based on MQTT multiple gateway networkings in above-mentioned steps three, and the feedback of home appliance disappears
Breath, which is routed to MQTT control ends, includes two kinds of situations, and a kind of is that the feedback message of home appliance is routed to all MQTT control ends,
A kind of is that the feedback message of home appliance is routed to specific a certain MQTT control ends.
The feedback message of home appliance, which is routed to all MQTT control ends, includes following small steps：
（1）, by step one constitute multilayer cascade network close structure in, any one gateway receives disappearing from home appliance
During breath, the local mobile control end list of inquiry obtains all MQTT control ends for being connected directly to the gateway.
（2）, then forward messages to each direct-connected MQTT control end.
（3）, information reporting is given to upper level gateway, and be sent to its next stage gateway.Higher level's gateway is received
Row message will also be sent to other subordinate's gateways in addition to the gateway for reporting the message except being sent to oneself higher level；Under
Level gateway is only handed down to subordinate when receiving upstream message, and each gateway can forward messages to all direct-connected MQTT controls
End processed, it is ensured that the synchronizing information of all MQTT control ends in intelligent domestic system.It is noted that being come from when subordinate's gateway is received
During the upstream message of higher level's gateway, subordinate's gateway no longer needs upstream message reporting higher level's gateway, otherwise can form broadcast
Storm.
The feedback message of home appliance, which is routed to specific a certain MQTT control ends, includes following small steps：
（1）, by step one constitute multilayer cascade network close structure in, any one gateway receives disappearing from home appliance
During breath, the local mobile control end list of inquiry judges whether to include purpose MQTT control ends, if being sent to the purpose in the presence of if
MQTT control ends simultaneously stop, and higher level's gateway is sent to if being not present.
（2）, higher level's gateway receive message, repeat step（1）, until stopping or being sent to service platform.
Compared with prior art, the beneficial effects of the present invention are：
1）The hub-and-spoke network topology of MQTT agreements is improved, the gateway topology of multilayer cascade is supported.Smart home after improvement
The MQTT Broker of service platform need not be managed from multiple gateways with a family simultaneously, and each family can only have one
Individual one-level gateway is connected directly to service platform, and suitable one family only provides an external interface, and remaining gateway is connected to one-level net
Close following；And when household internal has multiple gateways, user can go to control the family in different zones by different gateways
Electric equipment, without assert that specific a certain gateway could control the equipment.
2）Connection networking and the message route of multiple gateway are supported, a kind of side that multiple gateway networking is carried out by MQTT is realized
Method.This method, which can be supported to be divided home appliance according to custom rule in family, carries out safe and efficient Intranet in different zones
Control and small range management, and expand wireless-communication-capable area scope.Such as support household internal according to physical distance or hard
Part communication interface is divided into different districts domain, and such as room one is divided into region one, and room two is region two, facilitates user to difference
Region carries out different controls and management.

Embodiment
Embodiment of the present invention is described further with specific embodiment below in conjunction with the accompanying drawings.
The message route method cascaded based on MQTT multilayers of this example, is mainly made up of, step is as follows four steps：
Step 1：Multiple gateway networking based on MQTT：New gateway is added, home appliance is connected to new gateway.Specific networking flow is such as
Shown in Fig. 2, the gateway topological diagram of Fig. 1 multilayer cascade is ultimately formed.
A) local data base is first inquired about during gateways and starting with the presence or absence of the UID of itself.If being not present, basis
Snowflake algorithms generate UID, and UID is used to identify gateway, automatic the topic of subscription "/UID/# " of gateway.
For example start new gateway, new gateway inquiry generates UID less than UID according to Snowflake algorithms, and gateway is ordered automatically
Read theme "/UID/# ".
B) user configures the IP address of the upper level routing node of the node by web page.
C) UID gateways are attached with upper level gateway.If higher level's gateway identification is UID0, and is connected directly to intelligent family
Service platform is occupied, "/UID0/# " updates the route rule of higher level's gateway in local routing table by the routing rule of acquisition higher level's gateway
Then for "/UID0/# ", the current routing rule of itself is "/UID0/UID/# ".
D) upper level gateway receive UID gateways connection after, in the subordinate's gateway routing rule of itself add one "/
UID/#”。
E) UID gateways and startings equipment discovery procedure, by search and information matches home appliance SID and itself
UID, using UID/SID form as the globally unique identifier of home appliance, while gateway is recorded in the list of devices of itself
" SID " and routing rule.
F) USID is reported higher level gateway UID0 by UID gateways, and higher level's gateway is recorded in the list of devices of itself
" UID/SID " and routing rule "/UID ".
G) previous action is performed per one-level gateway recurrence, untill USID is reported to smart home service platform.
Here USID is then reported to smart home service platform by higher level's gateway UID0 due to direct-connected service platform.
Step 2：User control device, data route is descending, and idiographic flow is as shown in Figure 3.
A) user connects any gateway using MQTT control ends, such as connects and be designated UID0 gateways.
B) user sends control message and controls a certain equipment, such as it is that "/CONTROL/SID " controls are designated to send theme
SID equipment.
C) it is SID that UID0 gateways extract controlled device in outbound message using last "/" suffix
D) UID0 gateways search local device list, there is SID, and routing rule is "/UID "
E) control message that the issue of UID0 gateways is received, theme is "/UID/CONTROL/SID "
F) due to have subscribed theme, "/UID/# ", it is "/UID/CONTROL/SID " then to receive theme to next stage gateway UID
Control message, it is same to extract outbound message controlled device SID, search local device list and there is " UID/SID ", by suffix match
Understand there is SID, routing rule is "/UID/UART0 " then forwards the message to local serial ports UART0
G) SID household electrical appliances receive the control message from serial ports UART0.
Step 3：Facility information feeds back to all users, and data route is up, and idiographic flow is as shown in Figure 4.
A) when any one gateway receives the message from home appliance, the local mobile control end list of inquiry is obtained
Cut-off is connected to all MQTT control ends of the gateway, then forwards messages to each direct-connected MQTT control end.
Such as SID equipment states change, and generate equipment state information, and UID gateways are sent to by UART0, and UID gateways are first
The local mobile control list of inquiry obtains MQTT control end lists, and status message is sent one by one to being connected directly to all MQTT of itself
Control end.
B) higher level's gateway receives upstream message except being sent to oneself higher level, to be also sent to except reporting the message
Other subordinate's gateways outside gateway；Subordinate's gateway is only handed down to subordinate when receiving upstream message, and each gateway can be by
Message is transmitted to all direct-connected MQTT control ends, it is ensured that the synchronizing information of all MQTT control ends in intelligent domestic system.
Status message is sent to higher level gateway UID0 by such as UID gateways, higher level's gateway UID0 receive after by inquiry
Level routing rule, is transmitted to smart home service platform due to no higher level, is otherwise sent to higher level's gateway；Then gateway
UID0 inquiries other subordinate's gateways in addition to the gateway UID reported, due to not stopping then, are otherwise sent to subordinate's gateway.
The local mobile control end list of UID0 gateways inquiry simultaneously, forwards messages to each direct-connected MQTT control
End.
Step 4：Facility information feeds back to some specific user, and route data is up
A) when any one gateway receives the message from home appliance, local mobile control end list is inquired about, judgement is
It is no to include purpose MQTT control ends, if being sent to purpose MQTT control ends in the presence of and if stopping, it being sent to if in the absence of if
Level gateway.
Such as SID equipment states change, and generate equipment state information, and merely desire to notice and be designated UUID（
Universally Unique Identifier, general unique identifier）MQTT control ends, then included in status message
UUID, and UID gateways are sent to by serial ports UART0.UID gateways are received after message, extract purpose MQTT control ends
UUID, and local mobile control end list is inquired about with the presence or absence of UUID, if sending and stopping in the presence of if, inquired about if in the absence of if
Higher level's gateway routing rule, and it is sent to higher level's gateway UID0.
B) higher level's gateway receives message, repeats previous step flat until being sent to purpose MQTT control ends or service
Platform.
Higher level's gateway UID0 receives message and first parses purpose MQTT control ends, then inquires about local mobile control list judgement
It whether there is, and if being sent to the MQTT control ends in the presence of and if stopping, if being not present, notify its upper level gateway, by
There is no higher level's gateway in UID0, so being sent to service platform and stopping.
Above-mentioned steps are not limited thereto for the present invention preferably embodiment, but protection scope of the present invention, appoint
What those familiar with the art the invention discloses technical scope in, the change or replacement that can be readily occurred in, all
It should be included within the scope of the present invention.Therefore, protection scope of the present invention should using scope of the claims as
It is accurate.
