The utility model proposes a kind of multichannel communication, dominant frequency is checked meter and the novel networking mode of auxiliary frequency networking.
Being divided between frequency 470MHz ~ 510MHz is 8 channels, i.e. each channel occupancy 5MHz.Each channel divides and comprises dominant frequency and auxiliary frequency, and the front 3M of channel is as dominant frequency, and rear 2M is as auxiliary frequency.Dominant frequency is normally to check meter and the employed frequency of communicating by letter, communication comprising the order that allow to network, reply the order that allows to network, searches the child node order, the up/down row reports child node order (up is the communication that node arrives route, otherwise descending), heartbeat packet and answer heartbeat packet.Auxiliary frequency is that the node application networks and the employed frequency of monitoring networking application, is mainly used in networking.The wireless routing module in district is not arranged on different channels work on the same stage, before concentrator dispatches from the factory default value is arranged, and provides when the inquiry of foreground partition channel and arranges when the foreground partition channel function at the operation interface of concentrator.
Route is set up the path step by step according to the signal intensity of radio node, and records complete routing information, nodes records next stage nodal information and even higher level of node information.
During networking, network access node does not send the application networking commands in turn at the auxiliary frequency of 8 channels, switches to immediately dominant frequency after order sends and waits for the routing reply order; Route uses auxiliary frequency to monitor in default frequency range, after application that route receives node networks order, record node path information also corresponding band reply allow the order that networks, child node to receive order after record communications band and upper and lower level nodal information.Node only is operated in default frequency range after networking, dominant frequency communication, and auxiliary frequency is monitored, and no longer sends the application networking commands.
During newly-increased node, node sends the application networking commands in turn at the auxiliary frequency of 8 channels, switches to immediately dominant frequency after order sends and waits for the routing reply order; After node receives application networking order, use auxiliary frequency superior node to send new node application networking order on every side, report step by step route; After route receives new node application networking order, record node path information and reply permission networking order in corresponding band.
During deletion of node, route sends the deletion of node order, and the relevant path record of this node in the deletion route; The upper and lower level of node updates node relevant information, deleted node reverts to not network access node.
The node that networks sends heartbeat packet to the upper level relaying at set intervals, and replys the heartbeat packet of next stage node.If even higher level of node is not received the heartbeat packet of certain next stage node, and be diagnosed as this node break down after calling out nonreply, report to route, route is carried out network restoration according to all child nodes of newly-increased this malfunctioning node.
1. use novel networking mode and set up the valid wireless network.
(1) set up the one-level relaying: after working channel was set, route started networking.Route at first enters auxiliary frequency listening state, this moment all not network access node all be in application and enter net state, send application networking order auxiliary the taking place frequently of 8 channels in turn, route is monitored n minute (route is defaulted as 5, can arrange) at auxiliary frequency in the concentrator operation interface, after receiving node application networking order, directly deposit this node in Flash, as the one-level relaying, and get back to dominant frequency transmission permission networking order, receive node and really accept one's fate after the order, switches back auxiliary frequency continuation monitoring; Node records up path after dominant frequency receives to allow the networking order, and stops to send application networking order.
The newly-increased node of route nothing in 30 seconds, or listening period is overtime, and route is got back to dominant frequency, seeks 2 grades of relayings.
(2) set up the secondary relaying: after the one-level relaying is set up, route is used dominant frequency to send to the one-level relaying and is searched the child node order, this order is broadcasting command, all one-level relay swicthings begin to search next stage child node (secondary relaying) to auxiliary frequency, tentative 5 minutes of search time, after searching end, the one-level node is got back to dominant frequency.
After search time finished, route used dominant frequency by point-to-point mode, sent to the one-level relaying and reported the child node order, and the one-level relaying uses dominant frequency that the child node of oneself is reported, and sent to child node simultaneously and allowed the order that networks., child node is replied and is confirmed.The next stage child node of route, one-level via node and one-level relaying (being two-level node) is record path information respectively.
Route records successively and reports the path, sets up the secondary relaying.
The next stage child node that one-level relaying record route is distributed for this node.
The upper level relaying of child node record oneself.
(3) other low level relaying and secondary relaying are set up similar process.Shortest path, the maximum principles of signal child node the strongest, the network coverage are followed in choosing of node path.
2. increase the networking of augmenting of node, deletion of node newly.
The information of newly-increased/deletion of node is obtained in the download archives order that route sends according to concentrator.
(1) newly-increased node networking process is to set up relaying similar.Newly-increased node has just powered on and has been in non-networking state, uses auxiliary taking place frequently to send the application networking commands.
This moment, route was used dominant frequency to send all nodes of broadcasting to use auxiliary frequency to seek child node, find child node after, wait the child node information that reports to be sent.
In the networking process, preferentially use the high path of relaying rank, i.e. the shortest path principle.
The shortest path principle can realize in the following manner: node runs into rudimentary relaying superior and transmits the child node that this node can have access to, then automatic fitration, upwards do not continue transmission, relay reception to routing information directly select optimal path, active upload is to the wireless routing module.
(2) during deletion of node, if this node is leaf node, the wireless routing module is deleted path corresponding to this node and is got final product; If this node is via node, the relaying rank is n, and route need to the child node take this node as relaying be augmented networking.The process of augmenting networking is to rebulid n level and above rank relaying, if search passes up to and sets up n-1 level and above relaying less than these child nodes, the like, perhaps again networking.
3. the diagnosis of node failure and network restoration.
After node networks, contact every Fixed Time Interval transmission heartbeat packet and even higher level of node, after even higher level of node is received heartbeat packet, send heartbeat packet for this node and respond.If even higher level of node is not received the heartbeat packet of this node within the time interval of appointment, then begin to call out this node, do not receive response after, confirm as this node and break down, report to route and carry out network restoration.
Simultaneously, the next stage node of this node is not received the heartbeat packet response of this node, comes back to application and enters net state.Process and the newly-increased node (be in the node of applying for net state and all be considered as newly-increased node) of augmenting networking are similar.
The above only is exemplary embodiment of the present utility model, and all being equal to of carrying out under scope of the present utility model replace or improvement etc., all should be included within the protection domain of the present utility model.
