Detailed description of the invention

Elaborate a lot of detail in the following description so that fully understanding the application.But the application Can implement to be much different from alternate manner described here, those skilled in the art can without prejudice to Doing similar popularization in the case of the application intension, therefore the application is not limited by following public being embodied as.

The application first embodiment provides the method for a kind of LA Management Room communication, its schematic flow sheet such as Fig. 1 Shown in, this embodiment comprises the following steps:

Step S101, obtains the request communicated with the target device specified, and the described target device specified is by setting Standby mark is determined.

This step is the startup step communicated with target device；Start a communication process and need at least two unit Element: communication start instruction, the communication object specified；The two element is answered with communicating at different execution equipment Obtain in different ways with middle meeting.Wherein, described communication object i.e. target device, use this target The device identification of equipment determines.The device identification of target device can include the MAC of the network interface card such as smart machine The situations such as the string number of address, device name or equipment, so can adopt according to different situations neatly Use different types of device identification.Request with the target device communication specified refers to comprise above-mentioned two base One group of instruction of this communication element.

For better illustrating the present embodiment, using intelligent watch as the execution equipment of this method, with intelligent watch Certain application (APP) and intelligent home device (such as intelligent air condition) underwater acoustic remote control as a example by this step is described Detailed process.

Intelligent watch receives in the application of the APP to intelligent air condition remote control and carries out certain for certain intelligent air condition The click signal controlled, then with this click signal for starting the foundation of communication, send communication start instruction；With Time, from the information prestored, obtain the device identification of this intelligent air condition equipment to be controlled, as really Determine the foundation of communication object.

Illustrate as a example by the concrete communication process that above-mentioned intelligent watch communicates with intelligent air condition below.

Intelligent watch receives the operation that its intelligent air condition remote control APP is applied by user, and by the point of touch screen Hit operation and receive the instruction requiring to adjust air-conditioning design temperature.

Described APP application send communication start instruction at once, start a series of set up communication process, wherein, Including the device identification obtaining the described intelligent air condition realizing storage.The purpose of this communication is described in order to transmit Adjusting the order of air-conditioning design temperature, this is Content of Communication, at intelligent watch and the connection setup of intelligent air condition This Content of Communication can be transmitted afterwards.

When intelligent watch needs to communicate with intelligent air condition, the request communicated with intelligent air condition obtained The middle device identification simultaneously including intelligent air condition, this device identification typically has stored in intelligent watch, If not yet stored, then may need first to carry out mutually setting up between intelligent watch and intelligent air condition identification relation Operation, it is of course also possible to carry out Classical correlation while sending communication request, in such cases, need The operator of intelligent watch to be increased selects the step of communication object.

The device identification of intelligent air condition can include the MAC Address of the network interface card such as intelligent air condition, intelligent air condition The situations such as the string number of title or intelligent air condition, so can according to the respective practical situation of different application, Use different types of device identification neatly.

Step S102, it may be judged whether be currently connected to LAN.

Whether obtain effective LAN IP address according to this equipment current to can decide whether to be connected to local Net.The address of LAN is generally defined by related specifications, and what equipment obtained meets the office of related specifications definition The IP address of territory net IP address range is it is believed that equipment has been coupled to LAN, otherwise it is assumed that do not connect Receive LAN.The distribution service condition of concrete IP address, is referred to the specification definition being correlated with, as generally In the case of specification RFC1918 of IPv4 followed of local network address planning or specification RFC4193 of IPv6. For having, with above-mentioned or related specifications, the in the case of of deviating from, can judge according to the practical situation of network.

Described LAN is not limited only to cable network (LAN), it is also possible to is WLAN (WLAN), also wraps Including VLAN (VLAN) etc., the equipment that these networks are connected is physically all in adjacent to one another Position, it is simple to ensure the ageing of communication.

In previous step as a example by intelligent watch, the IP address that intelligent watch obtains can be checked, if intelligence energy Wrist-watch is currently without acquiring effective IP address, it can be determined that be not connected to LAN；Or intelligence hands The IP address that table currently obtains is not lan address, and the IP address obtained such as current intelligent watch is wide area The public address of net, or the IP address that current intelligent watch obtains is for linking local address (Link-Local Address) 169.254.*.*, then may determine that current intelligent watch is not connected to LAN.

Step S103, if being not currently connected to LAN, is then connected to a LAN that may be connected to and returns Return and judge whether to be currently connected to the step of LAN.

When being currently not attached to any LAN, then it is firstly connected to an attachable local Net, as being connected to a WLAN (WLAN).

Described WLAN (WLAN) includes the WLAN being able to detect that and has preassigned service The WLAN (WLAN) of set identifier (SSID), namely include and broadcast service set (SSID) WLAN (WLAN) and preassigned the WLAN (WLAN) of service set (SSID), This makes the WLAN searched for the most, even for not having broadcast service set identifier (SSID) WLAN, as long as having preassigned its service set (SSID), still can searched arrive.

After being connected to a LAN that may be coupled to, return step S102, again judge whether currently to connect Receive LAN.

Still as a example by intelligent watch, it is generally configured with being connected to the function of WLAN as portable equipment, If intelligent watch is currently not yet connected to any LAN, then the connection WLAN possessed first with it Function is connected to an attachable WLAN identified with service set (SSID).Institute State the phase that attachable LAN refers to that intelligent watch has been pre-configured with including service set (SSID) The WLAN of related parameter or be currently able to detect the WLAN of service set (SSID).

After intelligent watch is connected to LAN, returns step S102, again judge the most whether intelligent watch connects Receive LAN.

Step S104, if being currently connected to LAN, then judges whether deposit in the LAN being currently connected to At the described target device specified.

When being currently connected to LAN, it is judged that current connected to LAN in whether exist The concrete mode of the described target device specified has multiple, can utilize according to the practical situation of network and equipment Different procotols, sends request message in network and judges.Such as: utilize address resolution protocol (ARP), Whether Internet Control Message Protocol (ICMP) inquiry exists described appointment in determining the LAN being currently connected to Target device.

Additionally can also utilize other procotol or comprehensively utilize various procotol, obtaining in current network The device identification (such as string number) of the equipment connected or request device identification be as described in the setting of target device specified Whether the corresponding request of equipment response of standby mark exists described appointment in judging the LAN being currently connected to Target device.So can select flexibly to use different equipment marks according to the difference of practical situations Know.

To be currently connected to whether there is intelligence in the intelligent watch of LAN judges the LAN being currently connected to As a example by air-conditioning:

For the device identification of intelligent air condition be its media interviews control (MAC) address in the case of, then can be to Sending address resolution protocol (ARP) request message in the LAN being currently connected to, request is currently connected to The intelligent home device that IP address in LAN is connected feeds back its media interviews with controlling (MAC) one by one Location, if the media interviews returned in the response message that receives of intelligent watch control (MAC) address and exist and indication It is identical that the media interviews of fixed intelligent air condition control (MAC) address, then be judged as the local being currently connected to There is described device identification in net is the intelligent air condition that its media interviews control (MAC) address.If not receiving The media interviews comprising the described intelligent air condition specified control the response message of (MAC) address, then be judged as working as Before there is not the described intelligent air condition specified in the LAN that is connected to.

Similarly, for the LAN of IPv6, it is possible to use Neighbor Discovery Protocol (Neighbor Discovery Protocol) whether there is the described target device specified in judging the LAN being currently connected to.

When the device identification of intelligent air condition is its title, then can utilize Internet Control Message Protocol (ICMP), host name is set to the title of the described intelligent air condition specified, to the LAN being currently connected to Interior transmission Internet Control Message Protocol (ICMP) message, if receiving corresponding response message, then may determine that and works as Front network internal storage is at the described intelligent air condition specified.Described appointment is there is not in being otherwise judged as current network Intelligent air condition.

Step S105, if existing, then the LAN by being currently connected to leads to the described target device specified Letter.

The described target device specified is there is, then by the office being currently connected in the LAN being currently connected to Territory net and the described target device communication specified.

As a example by there is its intelligent air condition to be communicated in the LAN that intelligent watch is currently connected to, intelligence Can be communicated with described intelligent air condition by the LAN being currently connected to by wrist-watch.

Instruction can be sent to described intelligent air condition by the LAN being currently connected to by such as intelligent watch, Work to this intelligent air condition controls accordingly, as changed mode of operation, modification parameter etc., intelligence Energy wrist-watch can also be by the LAN being currently connected to, and reception obtains the duty or of this intelligent air condition A little parameters, such as current mode of operation, temperature index of setting etc. is so that related application uses.

Step S106, if not existing, then judges whether to be complete looking into all LANs that may be connected to Look for.

When there is not the described target device specified in the LAN being currently connected to, then need to sentence Break and whether be complete the lookup to all LANs that currently may be connected to.For WLAN, all The LAN that currently may be connected to includes the most all wireless offices that service set (SSID) can be detected Territory net has preassigned the WLAN of service set (SSID) with can't detect.

As a example by possessing the intelligent watch connecting wireless lan function, if its LAN being currently connected to The most do not find its intelligent air condition to be communicated, then judge whether to be complete and all intelligent watch are worked as Before the lookup of WLAN that may be connected to.LAN for currently may be connected to is only WLAN Situation for, all LANs that currently may be connected to of intelligent watch include the wireless local that can detect Although net one and WLAN two and can't detect but preassigned service set (SSID) WLAN three, then need to judge whether all to search the described intelligence specified in these three LAN Air-conditioning.

Step S107, if not completing the lookup to all LANs that may be connected to, then disconnects current connection To LAN and be connected to a LAN that may be connected to the most do not searched, and return judge work as Before whether there is the step of the described target device specified in the LAN that is connected to.

When there is also the LAN not searching described target device, disconnection ought be received repeatedly LAN, is connected to the LAN the most not carrying out searching the operation of described target device, returns and judges Step S104 of the described target device specified whether is there is in the LAN being currently connected to.

When there is not the LAN the most not searching described target device, due to by LAN with The communication of described target device is the most infeasible, in order to ensure the availability of communication, can disconnect and being currently connected to LAN, be connected to Internet, communicate with described target device.

So will not be because of cannot be caused by LAN and the described target device communication specified can not be to it Be controlled or obtain data from it, it is possible to be big by network delay, ageing slightly worse Internet with The described target device specified communicates, and controls it or obtains data, plays guarantee communication available The effect of property.

Still as a example by possessing the intelligent watch connecting wireless lan function, if intelligent watch is currently connected to Its intelligent air condition to be communicated is there is not in WLAN one, and WLAN one, and wireless office Territory net two and WLAN three did not the most carry out lookup, then disconnect the LAN one being currently connected to, from WLAN two and WLAN three select a WLAN, such as WLAN two, sets up With the connection of WLAN two, return step S104 judges whether exist in the LAN being currently connected to Described intelligent air condition.

If be complete the lookup of the WLAN that may be connected to the most all to intelligent watch, namely complete Become WLAN one, WLAN two and the lookup of WLAN three, and at these three network The most do not find the intelligent air condition to be communicated, then, disconnect the wireless office that intelligent watch is currently connected to Territory net, if intelligent watch possesses outside the described function being connected to WLAN, is also equipped with passing through telecommunications network Network accesses the function of Internet, then be connected to Internet, and by Internet and institute The intelligent air condition stated communicates.Realize the control to intelligent air condition or obtain from intelligent air condition reception corresponding Data.

The method that the present embodiment provides, is preferably applied to intelligent watch and controls the intelligence including intelligent air condition Energy home equipment, it is also possible to be applied to any control equipment to any Smart Home including intelligent air condition The control of equipment, for the equipment of Smart Home, owing to present position is relatively concentrated, at same local Communicate in net and control can ensure the ageing of communication to greatest extent.

Use the method that the present embodiment provides, it is possible to search for all LANs being connectable to, preferentially utilize LAN communicates with target device, it is ensured that communication ageing.

A kind of method that second embodiment of the application provides network device communications, has been set up with equipment room In case of communication connection, its schematic flow sheet is as in figure 2 it is shown, comprise the following steps:

Step S201, obtains the request communicated with the target device specified, and the described target device specified is by setting Standby mark is determined.

The request communicated with target device is generally called generation by the operation of user or application program, for Complete corresponding functions of the equipments, as controlled the function of target device, connect such as mode of operation or from target device Receive parameter etc., need to set up communication connection with target device, send instruction and message, receive data, carry out Communication.

The present embodiment still with intelligent watch and intelligent home device, as a example by the communication between intelligent air condition, i.e. refers to Fixed target device is intelligent air condition, and intelligent watch obtains the control requirement to intelligent air condition from the operation of user, As changed mode of operation or modification parameter etc., these requirements need to be sent to intelligent air condition by instruction, Namely intelligent watch gets the request communicated with intelligent air condition.And for example reception is needed to take when intelligent watch The duty of intelligent air condition or some parameters, such as current mode of operation, during the index such as the temperature of setting, It is also required to communicate with intelligent air condition contact, at this moment, can get and corresponding intelligence from corresponding program The communication request of energy air-conditioning.

When intelligent watch needs to communicate with intelligent air condition, the request communicated with intelligent air condition obtained In include the device identification of intelligent air condition, the device identification of intelligent air condition can include the net such as intelligent air condition The MAC Address of card, the situation such as the title of intelligent air condition or the string number of intelligent air condition, so can basis The respective practical situation of different application, uses different device identifications neatly.

Step S202, is connected with the foundation of the described target device specified by Internet.

For needing the equipment communicated with each other by network, mostly possess and access Internet Function.Access the most universal mode of Internet and be through the data service function that communication network provides Access Internet.Due to communication network wide coverage, by the accessed Internet of communication network In most of the cases can realize the communication of equipment room.It is international mutually that described target device generally remains access The state of networking is to control equipment and controlling.Time to be in communication with, can be first coupled to international mutual Networking, establishes communication connection by Internet.

Intelligent watch described in the present embodiment and intelligent air condition can access world interconnection by communication network Net.Wherein intelligent air condition has accessed Internet, intelligent watch get communicate with intelligent air condition please After asking, access Internet by communication network, set up communication connection with intelligent air condition.

Step S203, asks for its LAN list being currently able to be connected to the described target device specified.

After setting up communication connection by Internet with described target device, can be by the world being connected to The Internet, sends instruction to target device and exchanges information therewith.This step sends instruction to target device, Instruction comprises and asks for the request of its LAN list being currently able to be connected to it.

Described LAN as it was previously stated, include cable LAN, WLAN or VLAN.Right In WLAN, both included that its WLAN that can detect that also included having preassigned service set WLAN, so can obtain the service set of the WLAN that target device may be connected to (SSID), it is simple to subsequent treatment.Due to lan device location the most relatively, it is beneficial to protect The actual effect transmitted and send between card message.

Such as, after intelligent watch sets up communication connection with described intelligent air condition, intelligent watch is by having built up Internet communication connect, use the form (e.g., agreement and content etc.) made an appointment with intelligent air condition, to Intelligent air condition sends instruction, asks for the list of its LAN being currently able to be connected to intelligent air condition.

Step S204, its receiving that the described target device specified sends is currently able to the local train that is connected to Table.

After target device receives the request asking for its LAN list being currently able to be connected to, according to oneself institute The practical situation of place's network environment, the office that oneself currently may be coupled to that is that oneself is stored or that detect The list of territory net sends.

Such as, what the intelligent air condition in previous step received that intelligent watch sends asks for it and is currently able to be connected to LAN list after, search the LAN list that currently may be connected to oneself stored or detect oneself List is generated after the LAN that currently may be coupled to, then by described list by the interconnection Netcom having built up Letter connects, and is sent to intelligent watch according to the form (such as agreement and content etc.) made an appointment with intelligent watch, Intelligent watch receives intelligent air condition by the internet communication that has built up and sends its that return and be currently able to connect The LAN list arrived.

When current attachable LAN is WLAN, in described list, comprise wireless local The service set (SSID) of net.

Step S205, it is judged that whether have in described LAN list that this equipment is currently able to be connected to is available LAN.

After receiving the list that target device transmission is returned, check the office whether this equipment is connectable in list Territory net.

Such as the LAN that is currently able to be connected to by this equipment of the LAN in list and this equipment storage one by one Comparison, if a certain LAN had both been present in the list that target device transmission is returned to have is present in this equipment oneself In the list stored, then it is believed that whether there is this equipment in described LAN list and be currently able to connect The available LAN arrived.Otherwise it is assumed that do not have what this equipment was currently able to be connected in described LAN list Available LAN.

Linking objective equipment can also be attempted one by one and send the LAN in the LAN list returned, if can It is connected to, then it is assumed that in described LAN list, whether there is the available local that this equipment is currently able to be connected to Net.Otherwise it is assumed that there is not the available LAN that this equipment is currently able to be connected in described LAN list.

For the intelligent watch described in previous step, receive intelligent air condition and send its company of being currently able to of returning After the LAN list received, the LAN in described LAN list can be currently able to intelligent watch LAN in the LAN list being connected to compares one by one, if certain LAN had both been present in Intelligent air Adjust and be currently able in the LAN list being connected to, be present in again the LAN that intelligent watch currently may be connected to In list, then may determine that for intelligent air condition send return its be currently able in the LAN list being connected to There is the available LAN that intelligent watch is currently able to be connected to.

Can also judge successively intelligent air condition send return its be currently able in the LAN list being connected to LAN, the most whether intelligent watch is able to detect that, can if being able to detect that and being present in intelligent watch In the LAN list being connected to, then may determine that for intelligent air condition send return its be currently able to connect LAN list memory is currently able to the available LAN being connected at intelligent watch.

Intelligent air condition is sent to its intelligent watch being currently able in the LAN list the being connected to inspection returned Do not detect, but its service set (SSID) is the attachable WLAN of this equipment, then can attempt Be attached, if can connect, then may determine that for intelligent air condition send return its be currently able to connect LAN list memory is currently able to the available LAN being connected at intelligent watch.

Step S206, if described LAN list memory is currently able to the available LAN being connected at this equipment, Then sending to the described target device specified asks it to be connected to the request of described available LAN.

When described LAN list memory is currently able to, at this equipment, the available LAN being connected to, Communicated to connect by the Internet that is currently connected to, according to form predetermined with target device in advance, to Target device sends instruction, asks it to be connected to the local that described equipment is capable to connect to target device Net.

The intelligent air condition received for intelligent watch sends the LAN list memory returned and works as at intelligent watch Before the situation of available LAN that is connectable to, then intelligent watch is by the Internet being currently connected to, Request is sent to intelligent air condition according to the form (such as agreement and content etc.) made an appointment with intelligent air condition, please Intelligent air condition is asked to be connected to described available LAN.Described available LAN is intelligent watch and intelligent air condition The LAN being currently capable to connect to.

Step S207, receives the confirmation message being connected to described available LAN that target device sends.
