Description
Technical field
The invention belongs to computer fields, are related to the static routing dispositions method of lighting control system network.
Background technique
Lighting control system network is using the static Wireless MESH network disposed.Network node is routing node according to function distinguishing
And terminal node.Routing node fixed deployment as needed, forms wireless multi-hop backbone network.
Routing node refers to the network node for being configured to route forwarding function.And terminal node refers to without routing forwarding
Function, as the starting point of message or the node of terminal.
Since the transmission range of each node is limited, when source node sends data to destination node, it usually needs use
Multi-hop mode.So-called multi-hop refers to the node in network, does not need to be transmitted directly to destination, but can pass through phase each other
The node to connect forwards data, data is jumped to another node from a node, until reaching the destination.
After so-called forwarding refers to that routing node receives message, according to the destination address of message, assisted according to the routing of setting
View, obtains the path of next-hop, transfers data to next node.That is the Routing Protocol run on each routing node
It has guided in communication network and business datum is directed to the mechanism of destination node from source node.
The most common Routing Protocol of Wireless MESH network is all made of dynamic routing protocol at present, i.e. transmission path is transferred to completely
Router is automatically generated according to channel information, and when network topology state changes, topological condition is transmitted to by interdependent node
Adjacent node receives the node time update routing table of changing condition, completes route handoff, and again by the variation occurred before
Get forwarded to next node.But the cost paid is bigger network resource overhead, and needs powerful node processing power.This
Outside, the mode of dynamic routing, which is not ensured that, realizes networking fully according to deployment requirements.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of static routing dispositions method of lighting control system network, for
Disadvantages mentioned above realizes the routing function of lighting control system network using static routing technology, and compared to dynamic routing, it is not needed
Router continually exchanges routing table, is not take up network bandwidth, will not generate more new flow, this lamp small to bandwidth, more than message
It controls for grid, is very important.Meanwhile the information such as topological structure and network address will not be propagated in the sky, favorably
In network security.And compared to Flood routing agreement, and the propagation of the invalid data in network can be greatly reduced, improving network has
Imitate handling capacity.Each node is all made of fixed position and is disposed especially in lighting control system network, not will cause network and opens up
The dynamic for flutterring state changes, and therefore, realizes that network is disposed by the way of static routing, will preferably meet the need of lighting control system
It wants.
In order to achieve the above objectives, the invention provides the following technical scheme:
The static routing dispositions method of lighting control system network, comprising the following steps:
S1: according to the different group of geographical region division, the network address of each node is thus generated；
S2: each group setting one or more routing node, with being directly in communication with each other between group node, the sections of difference group
Between point, path is found by routing node and is attached；
S3: the data frame of different inter-node communications includes source address, destination address, next-hop node address and other controls
Domain processed；
S4: set static routing table includes destination address and next-hop node address in routing node；
S5: the static routing table of each routing node wirelessly connected during deployment, by configuration software into
Row configuration；
S6: static routing workflow: after routing node receives data frame, judge whether destination address is this node
Address, if so, otherwise the processing contained control information of data frame according to the control domain in data frame, judges whether routing node
It is forwarded；If so, next-hop node address corresponding to destination address in data in queries static routing table, will be connect
The data frame received is sent to checked in next-hop node address；It repeats the above process, until sending data to destination
Location.
Further, this method specifically:
S11: according to region division at tetra- groups of G1, G2, G3, G4, each node distributes an address containing group number；
S12: setting node 11,21,31,41 is respectively routing node；
S23: static routing table is configured for each routing node；
Wherein, the static routing table of node 11 is table 1:
The static routing table of 1 node 11 of table
| Destination address or group address | Next hop address |
| 2* | 31 |
| 3* | 31 |
| 4* | 31 |
The static routing table of node 31 is table 2:
The static routing table of 2 node 31 of table
| Destination address or group address | Next hop address |
| 1* | 11 |
| 2* | 21 |
| 4* | 41 |
S14: the course of work:
1. terminal node 14 sends out control command to node 42, data frame first is sent to routing node, routing node receives
To after data frame, 42 non-node address of destination address are judged；
2. judging that the data frame needs routing node to forward according to data frame control domain, then routing table 1 being searched, according to it
Group address 4*, checking in next hop address is 31, forwarding data frame to node 31；
3. node 31 receives data frame, 42 non-node address of destination address are judged；
4. judging that the data frame needs routing node to forward according to data frame control domain, then routing table 2 being searched, according to it
Group address 4*, checking in next hop address is 41, forwarding data frame to node 41；
5. node 41 receives data frame, 42 non-node address of destination address are judged, but be this group address, send data
Frame is to node 42；
6. node 42 receives data frame, judge that destination address 42 for this node address, handles data frame information loaded.
A kind of computer installation, including memory, processor and storage can transport on a memory and on a processor
Capable computer program, the processor are realized when executing the computer program according to the method.
A kind of computer readable storage medium, is stored thereon with computer program, and the computer program is held by processor
It realizes when row according to the method.
The beneficial effects of the present invention are: the present invention is directed to the characteristics of lamp sky grid, using the deployment of static routing
Method greatly reduces because of a large amount of network overheads caused by route maintenance.Routing table is built according to grouping simultaneously, is greatly reduced
The size of static routing table obtains stable network performance with minimum resource consumption, meets the huge lamp of number of nodes very well
Control system requirements.
