Specific embodiment
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below by control description of the drawingsThe specific embodiment of the present invention.It should be evident that drawings in the following description are only some embodiments of the present invention, forFor those of ordinary skill in the art, on the premise of not paying creative work, can be obtaining other according to these accompanying drawingsAccompanying drawing, and obtain other embodiments.
To make simplified form, part related to the present invention in each figure, is only schematically show, they do not representIts practical structures as product.In addition, so that simplified form is readily appreciated, with identical structure or function in some figuresPart, only symbolically depicts one of those, or has only marked one of those.Herein, " one " is not only represented" only this ", it is also possible to represent the situation of " more than one ".
In the prior art, device end A and device end B are connected into wide area network, make device end A, device end B correspondenceAPP A, APP B be installed on intelligent terminal, and wide area network is also connected into by intelligent terminal, APP A are referred to by sending controlMake to the corresponding vendor A background servers of device end A (which is also connected into wide area network), so as to allow vendor A background server to sendCorresponding control message gives device end A, realizes to the control between device end A.And APP B are also only capable of by said methodControl unit end B, APP B can not realize the control to device end A, and be limited to the presence of wide area network, if disconnecting wideThe connection of domain net, APP B also cannot be controlled to device end B, and in the same manner, APP A cannot also realize the control to device end ASystem.
The present invention makes the corresponding manufacturer's background server of each device end, device end, APP by adding control systemIdentical network is connected into, by the control system of transfer, the linkage between each device end is realized.For example：APP B control devicesTerminal A, device end A control unit end B, naturally it is also possible to which, as original, APP A control unit end A simply respectively setStandby being in communication with each other between terminal, manufacturer's background server, each APP is required for forwarding by control system, so as to realize differenceEach device end of ecosphere is linked.
In one embodiment of the invention, as shown in figure 1, a kind of device end control method based on MQTT, including：Step S200 obtains device end mark and device end operation information；Step S400 is identified according to the device end and describedDevice end operation information, generates the device end and identifies corresponding MQTT controls message；The MQTT is controlled by step S500Message processed is sent to the device end and identifies corresponding device end, controls the device end and performs the MQTT controls reportThe corresponding operation of text.
Specifically, the present invention is realized based on control system (that is, following device end control systems based on MQTT), each device end and control system are in same network (LAN or wide area network), so that each device end is carried outMutually link.MQTT (Message Queuing Telemetry Transport, message queue remote measurement transmission) is IBM exploitationsAn instant communication protocol, become the important component part of Internet of Things.The agreement supports all platforms, almost can be allNetworking article and external connection are got up, and are used to as sensor and actuator (such as allowing house to network by Twitter)Communication protocol.
The presence of device end mark ensures that MQTT control messages can be sent to corresponding device end, and MQTT controlsThe generation of message also complies with the MQTT message formats of device end；Identified according to device end operation information and device end, it is rawThe MQTT control messages of the corresponding device end of forming apparatus terminal iidentification, it is ensured that the MQTT control messages of generation can allow equipmentTerminal accurately reads and performs corresponding operation.Device end only receives MQTT control messages, and according to MQTT controlsMessage performs corresponding operation, and work of its conversion does not give device end to complete, the real-time for responding device endIt is significantly increased, is substantially increased the experience of user.
Preferably, step S200 include it is following any one：Step S210 is being preset when there is predeterminable event to occurThe corresponding device end mark of the predeterminable event and the device end operation information are searched in data base；Step S220Receive the device end mark and the device end operation information that control terminal sends.
Specifically, monitor predeterminable event to realize by corresponding APP, and APP can be mounted in control system,Can be mounted in as now on control terminal (intelligent terminal), for example：The electronics such as mobile phone, panel computer, intelligent robot setStandby terminal.When APP is mounted in control system, control system is understood and oneself monitors whether predeterminable event, if yes, meetingCorresponding device end mark and device end operation information are found in the presetting database of oneself, it is corresponding so as to controlDevice end performs corresponding operation.Predeterminable event can be the condition that user oneself is arranged, and gather with reference to certain device endTo information and trigger, for example：When user is arranged as someone in room and light grows dark, just turn on light, that control system can be receivedCorresponding sensor is (for example：Infrared sensor, light sensor) Monitoring Data fed back, when which reaches it is pre-conditioned when, justTrigger predeterminable event (this event of turning on light), then the corresponding device end mark of this predeterminable event will be found(which lamp opened) and device end operation information (turning on light).
It should be noted that the information collected with reference to certain device end and trigger, certain device end here canWith the device end for being integrated in being attached in control system (such as sensor), or with control system.For example：In advanceIf event is opened when TV, just light is dimmed, certain device end here is exactly TV, TV and control systemCertainly it is the relation of TCP connections, it is impossible to be integrated in control system.Therefore, predeterminable event is touched according to what information on earthSend out, be to need to be become according to the situation that user is arranged, certain device end of pilot process collection information is also respective change's.
In addition, when APP is mounted on control terminal, device end mark can be directly transmitted by user and device end is graspedMake information, it is also possible to determine whether that predeterminable event occurs by APP, it is right so as to search in the presetting database on control terminalThe device end mark answered and device end operation information are sent to control system.
It follows that only when predeterminable event is triggered, device end mark and device end operation information can be just obtained,Corresponding operation is performed so as to control corresponding device end.When the setting of predeterminable event ensure that each device end has standbyBetween, it is not to be in the stage for constantly working, reduces its unnecessary wasting of resources.
Preferably, the device end operation information includes：Device end capability code information and device end need to holdCapable operation information；Step S400 is specifically included：Step S410 is identified according to the device end, in default device endThe device end is searched in ability warehouse and identifies the corresponding device end and the corresponding MQTT of device end markControl message format；Step S420 is identified according to the device end capability code information and the device end, described pre-If corresponding device end ability information is searched in device end ability warehouse；Step S430 is believed according to the device end abilityBreath, the device end need the operation information for performing and MQTT control message formats, generate the device end correspondenceMQTT control message.
Specifically, preset device end ability warehouse to be provided in control system, preset device end ability warehouseSetting be also to ensure that even if control system (is not connected with vendor server) in the state of the wide area network that broken, it is also possible toDevice end mark and device end operation information according to obtaining is controlled accordingly.
As said before, device end mark can find corresponding device end, because which is in default device end abilityIt has been also carried out associating with the MQTT control message formats of device end in warehouse, accordingly it is also possible to look for by device end markMessage format is controlled to MQTT, MQTT control message formats are to ensure device end operation information is translated into device end subsequentlyThe key point of the control message that can be read.Each device end has its corresponding device end ability, therefore, equipment endEnd mark is to reduce the key factor of device end ability information, and further with device end capability code information in diminutionIn the range of make a look up, can more efficiently find corresponding device end ability information, substantially reduce data searchScope, reduces unnecessary communication process, improves work efficiency.Generating the corresponding MQTT controls message of device end is alsoThe corresponding operation of reading and execution for the ease of device end, because the device end operation information that control system is obtained is simultaneouslyThe MQTT control message formats that device end can read are not necessarily, the transformation process of control system is to ensure respectively to be in differenceThe key point that the device end of ecosphere can be linked.
The difference of the operation information for performing is needed with regard to device end ability information and device end, may be referred to following examplesSon, for example：Device end is a lamp, and its device end ability information is ON/OFF, brightness, flicker, color etc., and equipment endIt can be to open lamp, close lamp that end needs the operation information for performing；If current 1) the device end capability code information pair for obtainingAnswer be out, brightness, color；2) it is Huang that device end needs the operation information for performing open lamp, brightness to be transferred to 50%, colorColor；The operation that so last this lamp is performed recently is exactly not work from original, becomes the state of turning on light, and its color for HuangColor, brightness are 50% state.Certainly, even lamp, the device end ability information of every lamp be also it is different, therefore,Need for sending corresponding MQTT controls message according to the practical situation of every lamp.
Preferably, also include before step S200：Step S100 is worked as and the device end and the device endAfter corresponding manufacturer's background server establishes TCP connections, the log-on message that the device end sends is received, and described pre-If the corresponding device end mark of the device end is created in device end ability warehouse；Wherein, the log-on messageIncluding：The corresponding MQTT control message formats of device end and the device end ability information；Step S110 willLog-on message storage corresponding with device end mark is into the default device end ability warehouse.
Specifically, control system sets up the long connection mechanisms of TCP, main purpose with each device end and manufacturer's background serverIt is to control message to device end in order to ensure control system can receive/send MQTT at any time, it is ensured that the real-time of control.NeedIt should be noted that when a device end first time access control system, i.e. device end and the successful connection of control system TCPAfterwards, device end can be sent to control system the address (domain name or IP address add port) of its corresponding vendor server；MakeControl system is set up TCP with vendor server and is connected (this when needs exist for wide area network)；When control system person is successfully establishedAfter being connected with the TCP of vendor server, the information of device end successful connection can be fed back to；Then, device end can be whichLog-on message is sent to control system, so as to store the default device end ability warehouse into control system, and follows originalThe device end of definition and the MQTT initialization procedures of manufacturer's background server carry out message interaction process, complete device end withInitialization between manufacturer backstage between server, it is ensured that preset normally enabling for device end ability warehouse；It can be appreciated that willLog-on message storage corresponding with device end mark is into the default device end ability warehouse, and completes initialChange；It should be noted that above-mentioned this process needs the presence for ensureing to have wide area network.
After this process is completed, even if there is no the presence of wide area network, the equipment end sent by other control terminalsEnd operation information, it is also possible to the equipment of different ecological circle is controlled under the support in the default device end ability warehouse of control systemTerminal.
Preferably, step S110 includes：Step S111 judges that whether the MQTT controls message format in instituteState in default device end ability warehouse and exist, if it is not, then execution step S112, if so, then execution step S113；Step S112Add MQTT control message formats newly-increased in the default device end ability warehouse；Step S113 is by the equipment endEnd mark is associated with MQTT control message formats.
Specifically, the MQTT control message formats of each ecosphere should be identical, if according to identical ecosphereOther equipment terminal establish this MQTT and control message format, then new device end is without setting up new MQTT controlsMessage format, as long as completing which controls associating for message format with this MQTT, is easy to subsequent calls to obtain.And if not settingIf the MQTT control message formats of standby terminal, that must newly add in default device end ability warehouse, in order to rearContinuous calls.
Preferably, step S110 also includes：Step S114 judges whether the device end ability information existsExist in the default device end ability warehouse, if it is not, then execution step S115, if so, then execution step S116；StepS115 is added the device end ability information newly-increased in the default device end ability warehouse, and in the default equipmentThe corresponding device end capability code information of the device end ability information is created in terminal capability warehouse；Step S116Device end mark is associated with the device end ability information.
Specifically, their device end ability information of same type of device end is probably identical, if settingThere is the device end ability information of this device end in standby terminal capability warehouse, that is completely unnecessary and increases one newly againIdentical, it is only necessary to association；For example：When control system is connected with first lamp, created ON/OFF, brightness this twoIndividual device end ability information；And the second lamp, when being connected with control system, it has three kinds of device end ability informations：It is ON/OFF, brightDegree and color, then ON/OFF and brightness avoid the need for creating again, it is only necessary to association, and color is accomplished by re-creatingAnd associate.And if there is no the device end ability information of this device end in default device end ability warehouse, in order to follow-upCall, control, newly increase its device end ability information be it is necessary, it is and which is corresponding also for just with device end markConsideration is called in follow-up；And be directed to device end ability information and set up new device end capability code information and also allow forFollow-up calls and sets up.Device end ability information is to specify corresponding equipment with device end mark associationTerminal has corresponding device end ability information, is easy to follow-up maintenance and management, also allows for follow-up reduction when calling and searchesScope；And device end ability information and device end capability code information association, it is for subsequently through device end abilityCode information is searched corresponding device end ability information and provides guarantee.
Preferably, step S200 also includes：Step S230 is received control terminal and is sent by manufacturer's background serverDevice end mark and the device end operation information；Also wrap between step S200 and step S400Include：Step S300 judges whether the form of the device end operation information is that the device end identifies the corresponding MQTTControl message format, if so, then the device end operation information is that the device end identifies the corresponding device endMQTT control messages, and execution step S500, if it is not, then execution step S400.
Specifically, if the form of the device end operation information for obtaining is exactly device end mark, corresponding device end canWith what is recognized, that is equivalent to MQTT control messages of this device end, also just without the need for follow-up transformation process, can directly byThis MQTT control message is sent to the corresponding device end of device end mark and is operated accordingly, convenient, fast.For example：The device end operation information that APP A are sent by vendor A background server, which can be to allow arrange terminal A Direct Recognition,If being also destined to device end A, that control system also avoids the need for being changed, and is directly forwarded to device end A.NeedIf it should be noted that vendor A background server wants device end operation information (the i.e. MQTT controls for being sent to device end AMessage processed), necessarily device end A can be recognized for its internal device end capability code information for carrying；And if not factoryThe device end operation information that business's background server is directly sent to corresponding device end, its internal device end energy for carryingPower code information is that device end cannot read, accordingly, it would be desirable to be changed by control system.

Specifically, the device end of different ecological circle is realized mutually being connected by the control system of common connection, by controllingSystem realizes the conversion of control protocol (i.e. MQTT controls message format), simplifies the complexity of whole converting system, carries significantlyThe high real-time of device end response.And the connection of wide area network is not relied on, even if when wide area network disconnects, it is also possible to allowEach device end and control system are connected in identical LAN, make them still can substantially increase user with normal workExperience.
In another embodiment of the present invention, as shown in Figure 5, it is necessary first to after device end corresponding manufacturerPlatform server carries out the initialization of MQTT.Specific process may be referred to as follows, be illustrated below by taking home gateway as an example：
1st, device end A 510 no longer sets up direct TCP with vendor A background server 210 and is connected, but directly to officeControl system 100 in the net of domain sets up TCP connections, and in the family use, control system 100 here can be home gateway.In the same manner, device end B 520 also no longer sets up direct TCP with manufacturer B background servers 220 and is connected, but directly to localControl system 100 in net sets up TCP connections.
2nd, after TCP connections, by the address of its corresponding manufacturer's background server, (domain name or IP address add end to each device endMouthful) be sent to home gateway (certain internal working region, for example：MQTT proxy server).
3rd, after home gateway receives manufacturer's background server address, set up and manufacturer's background server by network 400TCP connects, it should be noted that need exist for the presence of wide area network.
4th, after home gateway and manufacturer's background server establish TCP connections, success message is informed into corresponding equipment endEnd, for example：Establish after TCP is connected with vendor A background server 210, control system 100 can be by success message annunciator endEnd A 510.
5th, device end sends to home gateway and registers the device end ability information of the device end and correspondingMQTT controls the message of message format.
6th, corresponding device end ability information and MQTT control message formats recorded local presetting by home gatewayDevice end ability warehouse, and safeguard the corresponding relation of these log-on messages and device end.Then send the note of device endThe successful message of volume information registering is to device end.
7th, device end is followed its of original definition and is carried out with the MQTT initialization procedures of corresponding manufacturer's background serverMessage interaction process, so as to complete the initialization between device end and manufacturer's background server, it is ensured that pre- in home gatewayIf device end ability warehouse is in follow-up smooth use.
Between device end intercommunication linkage control process (network 400 can be LAN in this process, orWide area network)：
1st, APP (operating on certain control terminal or on gateway) judges to need other one of control to set according to predeterminable eventStandby terminal, allows which to perform certain operation, so as to obtain above-mentioned described device end mark and device end operation information.As schemedIn shown in 5, APP A 310, APP B 320 can be run in control system 100, it is also possible to run on other control terminalsOn, for example：Mobile phone, intelligent robot etc..
2nd, APP will be set by remote method invocation (RMI) (if APP is operate in control system, not needing far call)Standby terminal iidentification, device end capability code information and device end need the operation information for performing be sent to home gateway (inCertain working region, for example：Device end ability is abstract and execution level).
3rd, home gateway (in device end ability is abstract and execution level) is according to device end capability code information and setsStandby terminal iidentification, inquires about in default device end ability warehouse, and bonding apparatus terminal needs the operation information of execution, generation to setThe corresponding MQTT of the corresponding device end of standby terminal iidentification controls message.
4th, device end mark and MQTT are controlled message by home gateway (in device end ability is abstract and execution level),It is sent to home gateway (in MQTT proxy server).
5th, home gateway (in MQTT proxy server) is identified according to device end and is sent to MQTT control messagesCorresponding device terminal, so as to realize the control to device end.
Control system as above, its working method cause the linkage between the device end of different ecological circle to be able to realityIt is existing.
It should be noted that above-described embodiment can independent assortment as needed.The above is only the preferred of the present inventionEmbodiment, it is noted that for those skilled in the art, in the premise without departing from the principle of the inventionUnder, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
