The comprehensive wiring mode that ubiquitous network adopts cable network and wireless network to combine.The original idea of Ubiquitous is no matter when anywhere no matter who can the meaning of access network, ubiquitous network framework is the development platform of the ubiquitous network equipment, comprise ubiqiutous Kernel (Open Source Code), network protocol stack, and other periphery agreement group.Be mainly used in embedded device exploitation.Application comprises network computing environment (LTE, Femto Cell, Wimax, animation, content); Home computing environments (intelligent appliance, compound household electrical appliances, POS, intelligent air condition); Terminal equipment computing environment (smart mobile phone, functional mobile phone, Intelligent hand-held equipment); Automobile computing environment (electric automobile, automobile navigation instrument, automobile audio).The application is with the network protocol stack code of oneself.This network configuration is applied in embedded development, and for embedded device is at limited RAM/ROM capacity, the network development environment of limited cpu performance provides development platform.In the present invention, center main control system and underground outstation adopt TCP/IP network service, underground outstation and switch, switch and hub, switch and radio access point, adopt ubiquitous network architecture communication between hub and each awareness apparatus, personnel's item location system adopts own RFID awareness apparatus, and the overall pie graph of ubiquitous network system is see Fig. 1.
Ubiquitous network adopts wired network communication to coordinate the mode of wireless communication to connect up, and cable network adopts RS485 network, and wireless communication adopts wireless terminal node to communicate with sink node.
Communication between wireless terminal node and sink node will by the switching of intermediate node and route, and radio node is the equipment using Power supply, in order to the useful life of extension device, needs to reduce sending the power consumption that redundant message saves communication process.Following three principles can reduce data traffic:
(1) node is according to the jumping figure layering of distance sink node (active network node), abandons the message of same node layer;
(2) handshake message that terminal node initiatively sends adopts short message;
(3) data message that destination address is clear and definite adopts long message, avoids the Multipath Transmission of long message.
The communication process of radio node registration is as follows:
1) the node jumping figure of radio node initial condition is 0xFF, and routing table is empty.
2) node sends Negotiation handshake message to neighbor node, adds the jumping figure value 0xFF of oneself.
3), after neighbor node receives handshake message, compare the jumping figure in handshake message and the jumping figure value of oneself, if be less than or equal to the jumping figure value of oneself, abandon this message, do not reply.If be greater than the jumping figure value of oneself, send the jumping figure value that response message tells oneself.
4) node does not receive response message (the jumping figure value of other nodes is that 0xFF or this Nodes are at information island) in time-out time section, keeps out of the way a time period, then resends Negotiation handshake message.Return step 3.
5) if node receives multiple response message in time-out time section, the jumping figure value of more all response messages, select wherein minimum hop count value to add 1 and be saved in RAM as oneself jumping figure value, simultaneously using the address of minimum for jumping figure value message be saved in oneself in routing table as Your Majesty to routing address; If the minimum message of jumping figure value has two or more, determine Your Majesty on routing address and backup to routing address according to the parameter such as RSSI or battery electric quantity.
6) node sends datagram to upper layer node, notice oneself jumping figure value and positional information, upper layer node is after receiving the data message of lower level node, the node address of oneself and jumping figure value are attached to this message, inquiry transmits message to upper layer node to routing table, is delivered to sink node always.Sink preserves this address of node, and hop count information and the routing iinformation distributed according to jumping figure, complete the registration of node.
7) sink node transmits all nodal informations to ground list server, and registration sink node subordinate address of node, routing iinformation is to ground central server.
Querying node message communication process is as follows:
1) routing iinformation of sink node checks destination node, hoc queries message.
2) sink node generates the message sending to destination node, and source address is sink node address, and destination address wants query node address, and data text comprises the layering routing iinformation of this node.Sink node sends this message to the 1st node layer.
3) ground floor node is subject to this message post analysis routing iinformation, the 2nd node layer finding this routing iinformation to comprise, and passes on this message, perform successively, until this message is delivered to destination node, complete the message communication of query manipulation to this node.
The inquiry response of terminal node is as follows:
1) terminal node tissue response insulation, destination address is sink node address, and source address is this terminal node address.
2) terminal node is inquired about to routing table, upwards sends this message to routing node.
3) on to routing node search oneself on to routing table, the intermediate node to more top transmits this message, until insulation reach sink node.
End node status information transmission is as follows:
1) terminal node organizing status information insulation, destination address is sink node address, and source address is this terminal node address.
2) terminal node is inquired about to routing table, upwards sends this message to routing node.
3) on to routing node search oneself on to routing table, the intermediate node to more top transmits this message, until insulation reach sink node.
The state information response of sink node is as follows:
1) routing iinformation of sink node checks destination node, structural state response message.
2) sink node generates the message sending to destination node, and source address is sink node address, and destination address wants query node address, and data text comprises the layering routing iinformation of this node.Sink node sends this message to the 1st node layer.
3) ground floor node is subject to this message post analysis routing iinformation, the 2nd node layer finding this routing iinformation to comprise, and passes on this message, perform successively, until this message is delivered to destination node, complete the message communication of query manipulation to this node.
The communication data format of above-mentioned radio communication comprises following message format.
(1) node initiatively sends the handshake message Negotiation(of message for routing inquiry);
(2) the query message Inquire of Sink node query node information;
(3) node status information communication message DATA.
(4) response message ACK.
Negotiation handshake message form is as follows:
| Order of shaking hands indicates | Sequence number | Source device type | Source device address | Password | Source node jumping figure | Message length | Data content indicates | BCC |
The initial value of general node jumping figure is 0xFF, and the initial jumping figure value of Sink node is 0.After network route completes, and sink node can the jumping figure of lower level node of direct communication be 1, and the lower level node jumping figure of 1 node layer direct communication is 2, the like.
The response of handshaking information is as follows:
| To shake hands response | Sequence number | Target device type | Destination device address | Source device type | Source device address | Password | Source node jumping figure | Data length | Data text | BCC |
Data text message form is as follows:
| Data-message indicates | Sequence number | Target device type | Destination device address | Source device type | Source device address | Password | Source node jumping figure | Data length | Data text | BCC |

Query messages form is as follows:
| Querying command | Sequence number | Target device type | Destination device address | Source device type | Source device address | Password | Source node jumping figure | Message length | Query contents | BCC |
Query messages generally has sink node to initiate, to its environmental information observed of some querying nodes.
The jumping figure of Sink node is 0.The node receiving this message continues the node that the backward jumping figure value that jumping figure value adds 1 is greater than oneself to forward this message, preserves amended jumping figure value.General node, when receiving jumping figure value and being greater than the query message message of oneself jumping figure value, abandons this message.
Inquiry response mode is as follows:
| Inquiry response | Sequence number | Target device type | Destination device address | Source device type | Source device address | Password | Source node jumping figure | Message length | Response content | BCC |
Wireless routing function adopts two modes to save communication flows.
1) radio node is according to the jumping figure value layering of distance sink node, abandons the message of same node layer transmission.
2) on radio node internal maintenance one to routing table (on to routing table preserve Your Majesty's node layer and backup upper layer node), the data-message transmission path of transmitting between node is single.Reduce redundant message.
The correspondence multi-zone supervision of radio node foundation and sink node, and the radio node of sink node direct communication is considered to be in ground floor, its jumping figure value is 1.Be two node layers with the secondary nodes that jumping figure value is the node direct communication of 1, the rest may be inferred.The message being sent to terminal node from sink node according to the route formulated in message to lower leaf transmission.Communication signal strength RSSI and the battery electric quantity of radio node foundation jumping figure and the upper layer node nearest apart from it are set up on one to routing table, on only to preserve the address of two upper layer node to routing table, one is Your Majesty's layer routing node, one is backup upper strata routing node, for empty when backup node does not exist.When this terminal node has message to transmit to sink node, this terminal node sends message to the main routing node in upper strata according to upper strata routing table, the main routing node in this upper strata transmits data to upper strata routing node according to its upper strata routing table, to the last passes to sink node.
Sink node preserves the route information table of all nodes, terminal node message is sent to comprise the layering routing iinformation of message, the intermediate node receiving sink node message analyzes the routing iinformation of message, according to routing iinformation formulate hierarchy to node-node transmission message, until this response message is transferred to terminal node.Terminal node is sending state information in sink node process, if intermediate node (the communication overtime duration of node increases progressively according to the number of plies) in time-out time does not receive the response of upper strata routing node, then think that the main routing node in its upper strata damages or power depletion, if there is route stand-by node, its message sent sends to sink node again by route stand-by node, and this route stand-by node of simultaneously upgrading is Your Majesty's layer routing node.When route stand-by does not exist, intermediate node, after data message communication overtime, revises the jumping value bit 0xFF of oneself, sends Negotiation message and again finds upper strata routing node to other nodes.The like, maintain the node route list of whole network.Route function is see Fig. 4.
RS485 is cable network, and it is interconnected that ubiquitous network and RS485 network pass through cable network.Its communication message is divided into Ubiquitous network to issue the query message of RS485 network and RS485 network sends to the state message of ubiquitous network and the response message of two class messages.
1) ubiquitous Internet Transmission is as follows to the message format of RS485 main equipment:
| RS485 querying command | RS485 network numbering | Destination device address | Source device address | Data length | Data text | CRC check |
Inquiry response mode is as follows:
| RS485 inquiry response | Destination device address | RS485 network numbering | Source device address | Response length | Response content | CRC check |
2) RS485 Host Transfer is to the state message form of sink node
| RS485 status report | Destination device address | RS485 network numbering | Source device address | Message length | Status data | CRC check |
