In order to realize control terminal 20 and multiple controllers 10 from organizing control into the net, specifically for control terminal 20 and more
A controller 10 devises unique Routing Protocol, including four equipment ownership, route discovery, route maintenance, mobile support steps
Suddenly.
Routing Protocol step 1：Equipment belongs to step
When adding household electrical appliance using smart mobile phone, home control device is selected for each household electrical appliance.Home control
Device is exactly in the communication range of the household electrical appliance and to be equipped with a controller of correlation function plug-in unit.In addition, being each household
Electric appliance adds identifier, for distinguishing the different household electrical appliance associated by each home control device.
Routing Protocol step 2：Route discovery step
Route discovery step include following a, b, c tri- step by step.
(a) control terminal sends out route requests
Control terminal 20 is opened, some household electrical appliance, control terminal is selected to judge the home control device of the equipment and obtain
Its IP address then sends out route requests message.Route requests message include mainly in have：Source IP address, destination IP
Location, device number, request serial number, type of message, along circuit node IP address collection, control command.Wherein " along circuit node IP address
The address of initial active node of collection ", subsequently forwards the control node of the routing request packet that the IP address of oneself will be added.The road
It is broadcast packet by request bag.
(b) controller handles route requests message
The routing module 12 of controller maintains following two tables：
Routing information request table, content include：Source IP address, purpose IP address, request serial number；
Routing table, content include：Source IP address, purpose IP address, next-hop ip address.
Fig. 4 is the routing discovering method flow chart of the expansible Intelligent household network control system of the present invention；
Step 601：Read message.
Step 602：Judge this node whether be the message next-hop node.If it is not, then abandoning the message.If
It is to then follow the steps 603.
Step 603：Judge whether type of message is route requests message.If it is route requests message, step is executed
604.If it is not, then correlation step content behind introduction.
Step 604：According to the information extracted from message<Source IP address, purpose IP address>Search routing information request table.
Step 605：Judge whether there is matched list item in routing information request table.If not provided, illustrating the node first
It is secondary to receive routing information request, therefore add new list item.If so, executing step 606.
Step 606：Judge whether the route requests are a new route requests.If in route requests message
Request serial number is less than or equal to the corresponding request serial number of the list item in routing information request table, illustrates not to be a new road
By asking, so abandoning the route requests message.It is no to then follow the steps 607.
Step 607：Update the route requests Serial No. route requests message of corresponding table item in routing information request table
Request serial number.
Step 608：Judge this node whether be route requests message destination node.If it is not, executing step 609；
If it is destination node, 610 and 611 are thened follow the steps.
Step 609:Due to not being destination node, so the IP address of local node is put into routing information request message
In " along circuit node IP address collection ", then proceed to broadcast the routing information request message.
Step 610：The control command carried in route requests message is taken out, and corresponding work(is sent to according to device number
Energy plug-in unit, relevant intelligent appliance is then forwarded to by plug-in unit.This way being placed into control command in route requests message
Control command can be made quickly to be sent to intelligent appliance, overcome general On-demand routing algorithm and need first to find that routing retransmits
The shortcomings that control command.
Step 611：After the completion of the step of front, the transmission path between control terminal and controlled device has been recorded
In " along the circuit node IP address collection " of routing information request message.It needs to send routing reply message to source node now.Road
By in reply message also carry " along circuit node IP address collection ", content in route requests message " along circuit node IP address collection " phase
Together.The path of the message transmissions is exactly reversely to send back source node along " along circuit node IP address collection ".In addition it is also necessary to root
According to " along circuit node IP address collection ", local routing table is established.
(c) controller and control terminal handle routing reply message.
Step 620：Judge that the message received is routing reply message.If it is not, in general, this message just
It is normal control message or routing error message, directly being forwarded according to routing table can.If it is routing reply report
Text thens follow the steps 621.
Step 621：According to " along the road IP address collection " carried in routing message, routing table is established.The format of route table items
For<Source IP address, purpose IP address, next-hop ip address>.Assuming that indicate IP address with letter, " along road IP address collection " content
For A, B, C, D, E, local ip address C can then establish two two-way route table items：
1 example of the routing table of table
| Source IP address | Purpose IP address | Next-hop ip address |
| A | E | D |
| E | A | B |
Step 622：Judge this node whether be routing reply destination node, that is, route requests source node.Such as
Fruit is that routing reply terminates.It is no to then follow the steps 623.
Step 623：According to the roads routing reply message Zhong Yan IP address collection, continue to forward routing reply message.
Fig. 5 is the route finding process schematic diagram of the expansible Intelligent household network control system of the present embodiment
For the practical work process of further instruction on-demand routing protocol, it is with the route finding process of Fig. 5 here
Example is illustrated.In Figure 5, there are one control terminal 20 and 3 controllers 10 (A, B, C).Control terminal 20 needs to control
Make an air-conditioning, the home control device of air-conditioning device B in order to control.
The process of route discovery is：1. control terminal 20 sends out route requests message first, which is broadcasting packet, institute
It can be received with controller A and C.After controller A and controller C is received, oneself non-purpose controller is found, by the IP of oneself
After " along the circuit node IP address collection " of route requests message is added in location, all continue to forward.Controller A will abandon controller C and turn
The route requests message of hair 1., because according to the routing information request table of controller A it can be seen that：Control had been received before eventually
Hold the route requests message sent 1..It can prevent route request broadcast from recycling in this way, also prevent similarly routeing and ask
The repetition asked is sent.Prevent controller A from 1. the route requests of the controller C forwardings received are sent back to control terminal.Controller B
After having received the route requests message of controller A forwarding 1., find oneself to be purpose controller, it then will be in route requests message
Control command 2. take out, air-conditioning is sent to by infrared receiving/transmission plug-in unit that can be in plug feature card 14.In addition, controller B
The address of oneself is added to " along the circuit node IP address collection " of route requests message, establishes routing table, and according to along circuit node IP
Address set, 3. reversed transmission routing reply message gives controller A, controller A to receive after, according to " the edge in routing reply message
Road IP node address collection " establishes routing table, and continues forwarding 3. to control terminal 20.After control terminal 20 receives, oneself is found
It is destination node, establishes routing table.After the completion of this process, control terminal 20, controller A, controller B form routing
Table.The transmission of subsequent control order is just directly forwarded using routing table.
By above introduction as it can be seen that the formed path transmission time delay of the route discovery is minimum.Since along this paths, control
Device B processed receives route requests message earliest, and sends routing reply message at first.In the example of fig. 5, controller C is excluded
Outside transmission path.
Routing Protocol step 3：Route maintenance step
Since intelligent home network topology does not change generally, controller 10 does not move.Therefore routing table can keep certain
Time.During this period of time, the control command that control terminal 20 is sent out is forwarded according to routing table, need not initiate a new road
By finding.Controller 10 need not actively initiate route discovery and route maintenance, save energy expenditure and routing cost.
But in order to adapt to network change, one renewal time of control software setting of control terminal (can generally be set as rather
Clock).Time one arrives, and control terminal 20 initiates new route requests.The update of related controller 10 routing in network.
In addition, if some controller 10 finds the mistakes such as link failure, routing error message is just sent to control terminal
20, control terminal 20 initiates a new route requests, to find new path.
Routing Protocol step 4：It is mobile to support step.
The control terminals such as smart mobile phone, tablet computer, mobility are stronger.It is moved for detection, the mobile inspection of control terminal 20
Survey the signal strength that module 23 will detect indoor each controller.If control terminal 20 moves, the signal of each controller
Intensity has obvious variation, will initiate a new route requests at this time, establishes new optimal routing.
Fig. 6 is the deployment schematic diagram of the expansible Intelligent household network control system of the present invention.
Expansible Intelligent household network control system and household electrical appliance networking in the present embodiment carry out household electrical appliance intelligence

Zigbee lamps can then install a zigbee plug-in unit on B2 nearby.The smart home device in kitchen is relatively more, can be in kitchen
Place a controller in room.
Step 2：Intelligent terminal downloads control software.It is smart mobile phone in embodiment, can scans the two-dimensional code, downloads control
Software.
Step 3：Each controller is configured, and adds associated household appliance to control terminal.If there is family's WiFi gateways,
Add gateway network title and password；Controller connects WiFi gateways, and IP address is obtained by way of DHCP.If no
Family's WiFi gateways then pass through control terminal static configuration IP address.
Step 4：Control terminal running control software selects a household electrical appliance, and sends out control command.Control command edge
The path that Routing Protocol is found is transmitted to household electrical appliance.
For example control terminal C1 wants to control equipment associated by B4, directly sends out control instruction to B4, and require no WiFi nets
It closes.If C2 wants to control the equipment associated by B4.Since C2 and B4 is apart from too far, WiFi direct communications or signal cannot achieve very
Difference, Routing Protocol are found by B2 transmission faster.Therefore a control path for passing through B2 to B4 from C2 can be established.
User actually uses the expansible Intelligent household network control system control specific process of household electrical appliance of the present embodiment
For：As shown in Figure 1, control terminal sends out control command, which is sent to controller C by controller B according to routing table.Control
Different types of plug-in unit is installed on device C processed, to which control command is transmitted to infrared air-conditioning, television set, zigbee light bulbs, bluetooth
On the different types of smart home device such as speaker.The system can also gathered data.If controller A is equipped with related plug-in unit,
It can be with information such as collecting temperature, humidity, air quality, gas concentration, intensities of illumination.Control terminal A sends out acquisition control first
Order, after each plug-in unit of controller A receives acquisition control order, by collected information：Temperature after being opened such as air conditioner,
Humidity, the photo after television set unlatching or zapping is transferred to control terminal, after user can know that mobile phone sends out control instruction
Control effect whether realize, to realize the feedback of control.

3. the present embodiment provides expansible Intelligent household network control system, the Routing Protocol of use has the following advantages that：
(1) most shortest time delay path can be found
Control terminal sends out route requests message, starts route discovery.The route requests message is broadcasting packet, along multiple
Path is sent to purpose controller.The route requests message of only most shortest time delay path transmission arrives first at purpose controller, and
Routing reply is sent to control terminal.Control terminal establishes routing table according to the routing reply that this is received earliest.Therefore it is sent out
Existing path is most shortest time delay path.
(2) route discovery does not influence the transmission of control command
The expense of on-demand routing protocol route maintenance is small, but general on-demand routing protocol is all advanced row route discovery
Data are then transported on, propagation delay time can be caused to increase in this way.To overcome the problems, such as this, control few for intelligent home network hop count
System orders brief feature, the Routing Protocol invented directly to carry control command, route discovery and control in routing request packet
System order transmission is carried out at the same time, control command transmission delay caused by avoiding route discovery.
(3) each controller need not actively carry out route discovery and route maintenance
Route discovery is initiated with route maintenance by control terminal, and each controller need not actively carry out route discovery and road
By safeguarding, energy expenditure and routing cost are saved.
(4) movement of control terminal is supported
Although controller does not move generally, control terminal, as smart mobile phone can be moved often.The control of intelligent terminal
Software inhouse has mobile detection module, judges whether to move by the WiFi signal intensity of monitoring controller.If detecting control
The WiFi signal intensity of device processed is changed, then initiates new route requests, finds routing.
(5) routing information request table can prevent the forwarding of route request broadcast cycle and repeat to forward.
Route requests message is broadcasting packet, for the invention routing information request table.There are one roads for each controller
By solicited message table, prevent the cycle of route request broadcast from forwarding and repeating to forward by sequence number size.
