Embodiment
It is apparent to illustrate invention, it is further elaborated below in conjunction with attached drawing：
Fig. 1 descriptions for system network topology figure, since system is no host-guest architecture, so equipment communication carrier,
It must be transmitted under multicast or the mode of broadcast, every equipment all may actively send information.What every equipment was sent
Information, other equipment can similarly receive.And the system device talk pattern, without connection, while dereliction is had no way of, and every sets
Standby relative to other equipment is all relations on an equal basis.Communication between equipment is without connection, while without shaking hands.The response of equipment
Mode is exactly to be handled by device address.If transmission information in include the device address, then the equipment be carried out act or
Returning response.
What wherein horizontal line represented is transport vehicle, its carrier can be wifi, zigbee, 315/433, infrared, can, has
Gauze network etc..Wherein equipment sends information, is similar to talk in a public environment, other equipment can be heard.Meanwhile
All devices are all below this big system.
Wherein, if system communication mode uses wifi or cable network, then create multicast come realize equipment it
Between communication.
The facility information, content include：Device address, device type, device location and facility information type.
First, device address
Every equipment can all have oneself mac address, which is the id of the equipment.The reception of equipment, by address come
Judge whether information is related to oneself, if related to oneself, post-processed.If unrelated with oneself, the information is abandoned.
The information of equipment is sent, and can is one-to-one, can is one-to-many, can be a pair of whole.Send in information, need
Address number is included, with destination address.If sending information wishes that armamentarium receives, destination address number is 0, destination address
For sky.Due to receiving device it should be understood that information is sent by whom, to be returned to response or reply.So believe sending
In breath, source address is also included.Address number, source address, destination address are needed in information (destination address can be sky)
After equipment receives data, number of addresses is contrasted first, if number of addresses is 0, illustrates that sending device notifies all set
It is standby, the information is handled at this time.If number of addresses is not 0, judge to receive in address, if comprising oneself.If comprising oneself, locate
Manage the information.
2nd, device type,
Every equipment, there is one or several types of oneself, such as " switch can be opened in an equipment, while
There is temperature input "
In equipment information content for transmission, device type information can be included, it is at this moment i.e. achievable one-to-many, while need not know
The specific address of these equipment of road.
The type of equipment, sets when dispatching from the factory, and can not change in use.
3rd, device location
Since intelligentized Furniture equipment has the concept of room location, every equipment operationally can also generally all be fixed on one
Position is run, and during system design, adds room location.
In equipment information content for transmission, room location information can be included, is coordinated at this time with room devices information, without understanding
Equipment specific address, you can control certain kind equipment in a certain room.
The room number of equipment, can be configured by host computer.
4th, facility information type
Facility information transport-type, can include, synchronizing information, control information, inquiry message, response message, return information
Synchronizing information therein, is that an equipment can to information, this type of information such as some synchronous system times of all devices
Without replying
The letter that control information therein is sent when setting system information or collecting device control to perform equipment for host computer
Breath, the information is without replying, it is only necessary to returns to implementing result.Equipment by this return information understand equipment whether packet loss or
How person performs state.
Wherein inquiry message for equipment understand other equipment operating status, or after new equipment addition system, it is necessary to
Other equipment understands the inquiry message sent during system information.The information needs the substantial reply of target device.
Response message therein, then be the response after the completion of execution after control information is sent to this equipment.
Return information therein, then be after inquiry message is sent to this equipment, after the information for obtaining itself storage, return again to
Give inquiry equipment.
Described avoids contention mechanism, its content includes：
Avoid conflicting, when equipment is sent, if other equipment is detected when being sent by other equipment, can be prolonged at random
When wait, this is avoided contention mechanism when applied to 315/433 being transport vehicle, and for wifi or zigbee, then the transmission carries
Internal portion has CSMA/CA conflict avoiding mechanism, it is possible to without considering.But for 315/433 equipment, due to not having, then need
Take into account.
The packet loss retransmission mechanism, its content include：Response in its further information protocol, includes sequence with retransmitting
Row number mechanism.
First, be directed to transmission packet drop, when occurring bulk information in network, due to processor or network carrier can
Packet drop can occur.At this moment retransmission mechanism is just needed.
To solve the problems, such as this, system solves the problems, such as this comprising two methods：Response is with retransmitting.
Equipment can understand need in the other information table according to equipment in command type and memory first before sending order
Want how many a return informations.
After equipment, which is sent, orders, other equipment response is waited, waiting time is 1 second, if in one second, institute's reply in need
Equipment, all replied one by one, then equipment can stop sending.
If after one second, not being connected to all devices reply, sending device can retransmit the order.Then again wait for replying.When
It is 1 second long.And so on, equipment is sent 3-4 times (can be set and be configured by system).Then judge to send failure.Stop sending out at the same time
Send.
But for the received equipment for crossing order, second of transmission of sending device can still reply, and may result at this time
Network busy, while the treatment effeciency of each equipment room substantially reduces.Solution for this problem is to increase in the protocol
Sequence number mechanism.
2nd, sequence number mechanism, mainly avoids equipment from have received equipment weight in the case where having treated the message
New transmitted message, is handled one time again.The mechanism detail is as follows：
When all devices initialize, sequence number is all 0, first can synchronization system sequence number when equipment enters system.Appoint
When what equipment often sends an information, one will be added on the basis of current system sequence number.
, can be according to the sequence number response of inquiry during equipment response, it is which time sends inquiry return equipment is understood the order
Response.
, will not renewal sequence number when equipment retransmits.
After receiving device normally receives the information of sending device, contrasted with the system serial number of oneself, if new sequence
Number it is more than the system serial number of oneself, then is updated the system serial number of oneself.At this time if sending device is sent again, due to
Will not renewal sequence number, so re-transmission sequence number is not more than the system serial number of oneself, at this time, then it is assumed that be with treated,
Then packet loss.
If receiving device packet loss, then will not then update system serial number.When sending device is retransmitted again, due to will not be more
New sequence number, when which receives retransmission of information, is still more than the system number of oneself with the contrast of oneself system number.So
Packet loss equipment can be handled normally.
When being communicated between system has large number of equipment, the sequence number of loss is possible to be blanked.The method for solving the problems, such as this
It is to increase by one group of record sheet in equipment, records the device number newly handled.When equipment normally receives, sequence number is recorded in this
In table, if after equipment packet loss, and receiving other information, then the system serial number of the equipment will become new sequence number.
The sequence number of packet loss will be blanked.If after increase sequence number record sheet, equipment retransmits, if being less than system serial number, goes pair
Processing equipment number is recorded than system, if there is the sequence number, is handled by receive packet loss.
Above scheme, you can solve the problems, such as packet loss, while can also solve to retransmit the reprocessing for the processed equipment brought
Problem.
The auxiliary acknowledgement mechanism, its content include：
Since system is no host-guest architecture, and system information is stored in each equipment, so system is supported in other equipment
Any addition, and can be with synchronization system information.Even if certain equipment failure, can also by access the situation of other equipment come
Understand system information.But a problem occurs at this time, in synchrodata, has multiple devices return information.At this time, it is synchronous
The equipment of information can then reprocess many garbages.Auxiliary acknowledgement mechanism is added to solve the problems, such as this, in system, at the same time
Also increase device role field in information content for transmission.
It aids in the address of answering equipment, is stored in the information table of every other equipment.
When First equipment adds network, the system can be created, the equipment upgrades to auxiliary answering equipment at this time.
, then can be to auxiliary answering equipment inquiry system information when second system adds network.It can lead to when transmitting for the first time
Cross the address that broadcast understands auxiliary answering equipment.After auxiliary answering equipment address is known in understanding, during synchronization system message, i.e., directly
Connect to auxiliary answering equipment address transmission data.Other equipment can not also go the information for handling new addition equipment please at the same time
Ask, reduce number of processes, increase efficiency.
The failure and election contest of further auxiliary answering equipment, its process are as follows：
When aiding in answering equipment in system, because certain reason goes offline or fails, system can be according to circumstances voluntarily competing at this time
Select an auxiliary answering equipment.To substitute original auxiliary answering equipment system information is provided for the other equipment newly added.
It is that equipment retransmits life identical three times to auxiliary answering equipment that it, which sentences the trigger condition of auxiliary answering equipment failure,
When making, and not obtaining responding, that is, prove auxiliary answering equipment lost contact.
At this time, auxiliary answering equipment election contest information is sent from inquiry equipment to system all devices, system is entered election contest
State.After other equipment receives at this time, election contest is proceeded by.It is to broadcast the resource information of oneself to set to all to campaign for flow
It is standby, while the resource information that other equipment is sent is received, then it is compared with the resource information of oneself.If the resource received
Have in information bigger or more than oneself.Then go off the air, if not bigger than oneself, can be broadcasted again once after one second,
After broadcasting three times, if not running into the equipment more than oneself resource, which can upgrade into auxiliary answering equipment automatically.
Claim information three times can be sent at the same time.After third time sends claim information, all devices store new auxiliary answering equipment
Address.
If in election contest process, original auxiliary answering equipment recovers, if judging, system is in election contest state, sends election contest and stops
Information.
Since new auxiliary answering equipment can send claim information three times after campaigning for successfully, statement letter is sent in third time
Before breath, any election contest Stop message, can all interrupt original election contest state.After if third time information is successfully transmitted, system election contest
State change is normal condition, and the auxiliary information address of other equipment is to change, and hereafter, original auxiliary answering equipment sends competing again
When selecting Stop message, due to the auxiliary answering equipment address of other equipment to be changed to new equipment address, then original auxiliary response is set
It is standby to be downgraded to conventional equipment.System denies recognition the equipment as auxiliary answering equipment.
Campaign resources may include：Cpu dominant frequency, free memory, remaining flash or hard drive space, the number of being randomly assigned.Election contest
When, contrast resource in order successively.
As shown in Fig. 2, Fig. 2 is after auxiliary answering equipment goes offline, system campaigns for the process of auxiliary answering equipment again：
In step 201, equipment can send inquiry message to auxiliary answering equipment, at this time can be by two kinds of situations, the first
Aid in answering equipment online, then can then enter step 202, the second situation goes offline for auxiliary answering equipment, at this time equipment
Inquiry message then can be overtime, after information time-out, then can enter step 203.
In step 202, which is normal condition, equipment and auxiliary answering equipment normal communication.
In step 203, which goes offline for auxiliary answering equipment, and at this time, equipment can obtain the competitive resource of itself.Together
When, system enters auxiliary answering equipment race condition, subsequently into step 204.
In step 204, itself competitive resource is sent to other equipment.
In step 205, when equipment is in holding state, the auxiliary answering equipment election contest from other equipment is received
After information, system mode is changed to auxiliary response race condition first.Then the competitive resource of itself is obtained, contrasts what is received
Competitive resource.If the resource received at this time is more than equipment own resources, then competition failure, enters step 207.If connect
Received resource does not have the equipment own resources more, then competition is got profit.Enter step 208.
In step 207, competition failure, then stop sending election contest data, then wait last to send setting for data
It is standby.
In a step 208, competition is got profit, then continue send election contest data, until send three times after, then without equipment send with
Competition when, then can enter step 209.
In step 209, it is that election contest is completed, equipment upgrades into auxiliary answering equipment from conventional equipment at this time, meanwhile, its
It is new equipment address that his equipment, which will also replace original auxiliary answering equipment address,.
In step 210, if auxiliary answering equipment recovers to reply in election contest after going offline, election contest letter can also be received
Breath, after equipment receives election contest information, can be directly entered step 211.
In step 211, former auxiliary answering equipment can send stopping election contest information to system other equipment.
In the step 212, all devices stop sending competition information, and the system mode of all devices is recovered from election contest state
Into normal state.
In step 213, when equipment is in competition transmission state, the stopping election contest from former auxiliary answering equipment is received
After information, it can enter in step 214.
In step 214, equipment can contrast the currently transmitted device address for stopping election contest, and the former auxiliary with oneself record should
Whether identical answer device address, if identical, enter step 215, if it is different, then entering step 216 abandons information i.e.
Can.
In step 215, both provable is same equipment, it is believed that original aids in answering equipment from the middle recovery that goes offline.This
When, stop sending competition information, while it is normal state to change race condition.
The device systems information storage mechanism, its content include：
Since the system is no master-slave system, it requires that each equipment in system has a system information, equipment into
Member's information, member status information, mission bit stream, can so solve when an equipment goes offline after, and new addition equipment still can be to
Other equipment in system understands system information, so as to solve in host-guest architecture, host goes offline, and causes asking for whole system paralysis
Topic.
Equipment after initialization, first can be to auxiliary answering equipment synchronization system information, after system information synchronously completes,
It can think oneself to be added to system.
Wherein, system information includes：Latticed form used in current system (e.g., wifi, zigbee etc.), current system
The configuration of middle latticed form or parameter, all number of devices in current system, the time in current system, in current system
It is whom to aid in answering equipment, all room numbers in current system, and the title of room number, all tasks in current system
What has, and in current system, some basic informations of other equipment members and some expansion list items etc..
To meet the expansibility of system, system also includes some variable informations.These information are substantially in the form of a table
Deposit in systems.After if new equipment adds legacy system, to meet new system performance, there may come a time when that some tables can be increased.This
A little tables, there may come a time when it is that legacy system is not present.For new equipment when adding legacy system, into system, synchronously these are variable
Table.Strengthen set expandability.
As shown in figure 3, Fig. 3 is the overall process that equipment adds system after the power is turned under the system.Wherein comprise the steps of：
In step 301, device power, completes a series of initialization procedures, including, equipment itself initialization, io
Initialization, all kinds of peripheral hardware initialization, and system information initialization.
In step 302, after the completion of the initialization of device power various information, it is that auxiliary response is set that whom, which starts to system interrogation,
It is standby, two kinds of possibility can occur at this time, the first, auxiliary answering equipment is found, is entered step【303】.Second, auxiliary response is set
It is standby not find, then enter step 305.
In step 303, synchronization system information is started, comprising：The arrange parameter of transport vehicle, the specific room number of system
And room title, the facility information situation of other equipment, the mission bit stream of system etc..Synchronizing information is divided into two contents,
First is fix information, and system has many fix informations, these information can be synchronous in order.
In step 304, when synchronously completing all system informations, equipment adds system sign and is recorded.Into wait
Coomand mode.
In step 305, situation about not found for ancillary equipment, at this time, equipment can send auxiliary answering equipment competition letter
Breath, can be divided into two kinds of situations at this time.The first situation is in system, and containing other equipment, the second situation is in system, is free of
There is other equipment.The equipment is first equipment for entering system.
Within step 306, the first situation is that equipment competition information has not timed out, and just has begun to receive after sending election contest
To the competition information of other equipment, other equipment is included in proof system at this time.So equipment enters step at this time【308】Deng
Treat that election contest is completed.The second situation is overtime to send competition information, it was demonstrated that the equipment is first equipment for entering system.This
When, equipment can enter step【307】.
In step 307, since the equipment is the equipment of first addition system, so the system of founding, while change certainly
Own equipment is auxiliary answering equipment.
In step 308, after the completion of waiting auxiliary answering equipment election contest, step 303 can be entered.
More equipment integration of operation mechanism, its content include：
The communication of host computer and system, the final form of system are by host computer, and setting command is sent to system.When being
When some node meets the condition of setting command in system, it is possible to achieve setting acts, the action with equipment in control other systems.
Reach joint-action mechanism.When new host computer adds system, auxiliary answering equipment, after finding, first synchronization system also can be first found
Information.When host computer needs to send order, then setting command can be sent to population of devices, population of devices receives setting command
When, regardless of whether it is related to oneself, the setting command can be all saved in into the storage device of oneself.Returned at the same time to host computer
It is multiple.
Communication between equipment, after being set by host computer, system can realize action control, timing controlled.Collecting device,
Collection value is judged, then output equipment is controlled, is connected so as to fulfill thing with thing, reaches Automatic Control.Due to being
System order, exists and in every equipment, so when setting after collection value is triggered, collecting device can actively send commands to defeated
Go out equipment.When output equipment receives order, parsing is acted and performed.Reach the effect of acquisition control output.
The Controlling principle of system equipment is, if in control information, having the relevant information of oneself, then handling, if do not had
The relevant information of oneself is not handled then.Between equipment and equipment, you can to ask for collection information mutually, control can also be sent mutually
Information processed.At the same time can striding equipment species.
The communication principle of system is, due to not establishing connection, so target device does not record the mark of communication, communication symbol
Established by inquiry or control device.What equipment is asked, what is just answered.If being asked the problem of identical, can answer again
Once.And the content inquired, recorded by inquiry equipment.
Transport protocol its content in system includes
General information protocol information is formed
Response message agreement is formed
Return information agreement is formed
The Chinese parsing, its implementation are：
The system can use Chinese to set in the setting up procedure by host computer, and equipment is receiving Chinese information
When, by analytical algorithm, the expression and significance in command statement is analyzed, so as to fulfill the purpose of Chinese control is passed through.
For system, equipment has the title of oneself in itself, while can be by the position at place, while also has equipment
Behavior.So according to this principle, command statement can be segmented.
Further Chinese word segmentation process such as Fig. 4：
In step 401, equipment, which first can store the keyword of oneself, becomes tabular form, and then word is classified, than
Such as equipment word, behavior word, room word.After initialization number, 402 are entered step.
In step 402, equipment can wait Chinese order to be received.
In step 403, equipment have received Chinese character string, then enters step 404 and start to segment
In step 404, equipment is stored in list from keyword first, extracts a word in a part of speech, Ran Houyu
The Chinese character string received is contrasted, i.e. step 405.
In step 405, character string will be received with after keyword contrast, step 406 is entered if keyword is found, if
To find keyword, then step 404 is returned to, continue to extract next word in part of speech.Then proceed to contrast.
In a step 406, after contrasting successfully, the word part of speech is recorded, records the word label of the word, then makes reception word string position
Next word is moved on to, enters step 407.
In step 407, judge whether to be displaced to suffix, if being displaced to suffix, enter step 408 and start to parse
Word segmentation result.If not being displaced to suffix, return to step 404 continue to extract it is such, then compare receive word string in word.
Further word segmentation result resolving such as Fig. 5：
In step 501, participle record list is obtained, subsequently into step 502
In step 502, according to part of speech, judge whether to match with local equipment name, if with room number where the machine
Match somebody with somebody, if matched with the behavior name of the machine.
In step 503, if part of speech is matched with local equipment name, recording equipment mark, then branches to step 506.
If mismatching, continue to judge in next step.
In step 504, if part of speech and room name-matches where the machine, record room mark, then branch to step
Rapid 506.If mismatching, continue to judge in next step.
In step 505, if the equipment behavior name-matches of part of speech and the machine, recording equipment behavior mark, and seek note
Record behavior label.Then branch to step 506.Continue to judge in next step if mismatching.
In step 506, judge whether to be extracted all records, if extracting all records, then step 507, if not having
Extract all records, then then return to step 503 and continue extraction record.
In step 507, to record make a decision, if to control a certain equipment, then as long as meeting device flag at the same time,
Room mark, equipment behavior mark are all recorded the information that control local equipment is included in i.e. provable sentence.Then enter step
Rapid 508.Otherwise the Chinese sentence for illustrating to receive not is control local equipment, then enters step 509, unrelated with oneself not go
Processing.
In step 508, illustrate that command statement meets the condition for making local equipment perform response apparatus behavior, then basis is set
Standby behavior label, performs response condition.
When in use, sentence order is sent to each equipment of system, every equipment can all be recorded according to after parsing
Corresponding mark, meet mark can perform action, not meet will not handling for mark, in this case, you can with reality
Now to the control of distinct device.Meanwhile qualified collecting device can be made to send Chinese, to realize that collection is set by setting
The standby control to output equipment.
