Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.
As shown in Figure 1, in the network-building method and device embodiment of a kind of chain communication network of the present invention, its network-building method comprises the steps:
Whether step S11 receives the information that network element is sent, and in this way, performs next step; Otherwise.Repeat this step.In the present embodiment, the chain communication network for the vehicle carried electronic label on a rail vehicle or form after train marshalling list is described.In the present embodiment, this communication network, except the above-mentioned electronic tag be arranged on each vehicle, also comprises the first equipment of the row be arranged on respectively on headstock and the Train End Equipment being arranged on last vehicle of train; These equipment and electronic tag, according to the spread pattern of rail vehicle, define a chain communication network at least in physical arrangement; In fact, after using the method in the present embodiment, this communication network also forms a chain network in route or in logic.Wherein, the first equipment of above-mentioned row is first-in-chain(FIC) equipment, and Train End Equipment is last-of-chain equipment, the vehicle carried electronic label be arranged in therebetween is then endowed and its physical location same logical location at the physical location of train according to its place vehicle, thus forms a chain communication network.In the present embodiment, above-mentioned multiple electronic tag (i.e. the network element of this communication network) successively between first-in-chain(FIC) equipment and last-of-chain equipment has the different network addresss (this network address comprises identification code or the ID code of this electronic tag) respectively.When above-mentioned train marshalling list completes and advances, the position that all-network unit (comprising the first equipment of row and Train End Equipment) in above-mentioned chain communication network arranges according to it, headed by described first-in-chain(FIC) equipment (namely by this first-in-chain(FIC) equipment), arrange equipment by route successively, this route arranges equipment for carrying out information interaction with the chain grid cell passed through and the current network element information passed through being sent to the network element passed through; Namely when train arranges equipment by above-mentioned route, network element on train can be activated, equipment is set with this route and carries out data interaction, receive the data (these data are the network element parameters being arranged equipment before this vehicle by route) that equipment is set from route on the one hand, upload the parameter of oneself on the other hand, comprise device type and address.Like this, when the rolling stock of train arranges equipment by above-mentioned route, each network element all knows the address of the network element before it, has namely arrived the routing forwarding address of this unit, has constituted the communication network of a chain.In this step, judging whether exactly to receive the data come from the network element transmission on rail vehicle, when not receiving any data, repeating this step, continue the data of the network element transmission waited on train; When data is received, next step is performed.
Step S12 obtains the data of indication equipment type and device address in above-mentioned information: in this step, processes the data received, and obtains information wherein.In general, above-mentioned electronic tag or to arrange the data that first equipment or Train End Equipment upload be all transmit with the form of packet.After receiving such packet, need choosing to unpack process to it, obtain data content wherein; And then take out in the content of the assigned address of these data obtained, just can obtain the information of being correlated with, such as, the type of equipment and its network address.In this step, obtain the device type of this network element of expression and the data of the network address that network element transmission comes, this network address normally identification code of this equipment or electronic tag or ID code in the present embodiment.
Step S13 judges this network element whether first-in-chain(FIC) equipment, in this way, performs step S14; Otherwise perform step S15.In the present embodiment, for network element and first-in-chain(FIC) equipment, although be all regarded as the part of network, arrange equipment at it through above-mentioned route, the mode of process is not identical.This is that it is arranged on the headstock of train because first-in-chain(FIC) equipment arranges first equipment exactly, and when train operation, arranging first equipment is the network components being arranged equipment in whole communication network the earliest by route, and it has special status in the present embodiment.In this step, judge to transmit by the device type obtained in data the first equipment of whether row that data come.In the present embodiment, the device type arranging first equipment is the code of a setting in advance, and it is different from any parts in this network.When finding that the device type in the data received is the code of this setting in advance, just can determine that the equipment of uploading data is the first equipment of row.
It is the first that this network element addresses is put into the first blank inventory by step S14: in this step, owing to judging to arrange with route, equipment carries out data interaction is the first equipment of row, and for the communication network in the present embodiment, this equipment can not initiatively carry out alternately with other network element, in fact, in communication network in the present embodiment, only have Train End Equipment initiatively can initiate data communication; Being in Train End Equipment and arranging network element between first equipment also can not initiatively initiating communication, and it is only that the route inventory stored according to oneself forwards after receiving the data or instruction that other network element sends.So at the present embodiment, arrange first equipment and do not have routing table, routing configuration equipment does not need to carry out routing configuration to the first equipment of above-mentioned row yet, and is only be recorded in the first inventory its address.But be first by the network element of above-mentioned routing configuration equipment in whole network owing to arranging first equipment, so, need its address to be recorded in the first inventory of a new or blank, before this route arranges equipment, other communication networks are configured and the first inventory obtained to be different from, meanwhile, the starting position address of the first equipment of row being placed on this first inventory will be needed.So, in this step, before record first-in-chain(FIC) device address to the first inventory, described inventory is formatd, eliminate may exist in the first inventory before the data that carry over, make it become blank.After executing this step, return step S11.
Step S15 sends existing first inventory to this network element: in this step, not the first equipment of row due to what judge that the current routing configuration equipment that closing the book carries out information interaction, show that arranging first equipment passes through, like this, the address of all all-network unit before this compartment (or identification electronic tag that this compartment is installed) has been described in first inventory, the arrangement of the network element addresses in this first inventory has certain rule, near the vehicle carried electronic label address in this compartment, its position is the closer to the top of this inventory, first position in first inventory, what record is the address being close to this compartment and being positioned at the vehicle carried electronic label on this compartment preceding carriage.So, in this step, this first inventory is sent to the above-mentioned equipment that arranging with route and carries out in mutual network element (electronic tag or Train End Equipment).Network element receives after described route arranges the first inventory that equipment sends, and it can be used as routing table to store; Described network element when carrying out network service according to described routing table address by default, its address of selective sequential from top to bottom.
Step S16 moves the data in existing first inventory, the address of this network element is put into the first place of existing first inventory, obtain the first new inventory: in this step, owing to obtaining type and the address of the current network element passed through, and in order to make next network element can obtain its routing address, need the network element addresses obtained to join in above-mentioned first inventory.For this reason, needing first to move the data content in existing first inventory, vacating first position of the first inventory for placing the address of the network element passed through, and then by this address stored in above-mentioned position.Specifically, in this step, first the data with existing content of current first inventory is moved integrally the distance of an address to the rear of this inventory or below, make its inventory starting position vacate the memory space that can hold device address data; And then the current device address obtained is recorded to the above-mentioned of described first inventory vacates in space, obtain new current first inventory.After executing this step, return step S11.
Like this, according to above-mentioned steps, when train arranges equipment through route, above-mentioned steps constantly repeats, and often through a vehicle, just performs the part in an above-mentioned steps or above-mentioned steps.Like this, make each vehicle carried electronic label and Train End Equipment can both obtain its route list exactly, thus realize the logic configuration of this chain communication network, realize networking.
In the present embodiment, above-mentioned routing device can be multiple, and multiple routing device is separately positioned on the rail limit, station of diverse location; Train all refreshes its routing table according to above-mentioned steps when arranging equipment by a route at every turn again.In addition, after network organizing, when the address of chain grid cell as found in its route inventory in communication process is not responded, be maybe that route is unreachable to by this address by this address mark by deleting in its route inventory.
In the chain communication network of the present embodiment, the communicating node device at two ends is called first-in-chain(FIC) equipment and last-of-chain equipment, is different from each communicating node device in centre.In this network, the transmission of information initiates from last-of-chain equipment, progressively converges to first-in-chain(FIC) equipment.Except first-in-chain(FIC) equipment, a routing table is all there is in each communicating node device in this chain network, have recorded all neighbor node device addresses receiving this equipment transmission information, can be referred to as route entry, these route entries are noted as first-selected route, secondary routing respectively by, the 3rd route etc.
When this node device needs to send message, headed by default objects address, select route entry address, select the address of route entry to communicate if first-selected route unavailable (namely destination address equipment is without response, communication failure) then attempts use time, process successively.
If when route table items is empty, this equipment initiatively can not initiate information interaction, but can respond the message request received.In first-in-chain(FIC) equipment, routing table does not exist, and this equipment only can response message, and initiatively can not initiate information interaction.
In the present embodiment, when a chain communication network is organized temporarily, each communicating node device in network all needs to obtain current recent route information, and what this network can be real completes networking, realizes the transmission of information with mutual.For this reason, in the present embodiment, use routing configuration equipment, for communication node each in chain communication network provides current network routing iinformation, realize internodal effective networking.
Specifically, in the present embodiment, first-in-chain(FIC) equipment is just mounted in the communicating node device of train stem locomotive, and last-of-chain equipment is then mounted in the row tail communicating node device of last vehicle of train, and intermediary device is just mounted in the communicating node device often saved on rail vehicle.Routing configuration equipment can realize information interaction with nodes equipment, and its installation site is fixing, when train by time carry out routing configuration.When first-in-chain(FIC) equipment, intermediate equipment, when last-of-chain equipment sequentially passes through routing configuration equipment successively, routing configuration equipment is mutual with it one by one, recognition node device type, device address, and send to node device to be stored in routing table current network routing iinformation, complete the renewal of network route, realize effective networking.Such as, a marshaling orbiting, routing configuration equipment is installed in orbit, and when train operation is by this section, each communicating node device that train is installed will successively by routing configuration equipment.Its detailed process is as follows:
Starting stage, when first-in-chain(FIC) equipment is by routing configuration equipment, routing configuration equipment initiates information interaction, and identification equipment type also records its device address; When first intermediary device is by routing configuration equipment subsequently, identified device type and address, receive the routing iinformation (first-selected route: first-in-chain(FIC) device address) of routing configuration equipment transmission and be updated in routing table, this routing iinformation is designated as first-selected route, and alternative route data does not exist then for empty; Second intermediary device, by routing configuration equipment, is identified equally, receives routing iinformation (first-selected route: the first mediation device address; Secondary routing is by first-in-chain(FIC) device address); 3rd intermediary device, by routing configuration equipment, is identified equally, receives routing iinformation (first-selected route: the second mediation device address; Secondary routing is by first mediation device address; 3rd route: first-in-chain(FIC) device address).
As above repeat, just can configure all rail vehicles.The number of alternate routing is subject to the reliable communication distance limit of two node communication equipment; When last-of-chain equipment is by routing configuration equipment, receive routing iinformation, in network, all node devices complete the renewal of route.
In the present embodiment, the installation quantity of routing configuration equipment is indefinite, position, station entrance-exit can be deployed in, if train is the interior change that marshalling occurs AT STATION, also by routing configuration equipment, the routing table of all communicating node device in this chain network can be upgraded after departures, guarantee the validity of network route.
As an example, Fig. 3 gives the schematic diagram of the rail vehicle in this city embodiment.In figure 3, a, b, c, d, e, f and g represent the vehicle carried electronic label that vehicle is installed respectively.There is a routing table in each label, such as, in Fig. 3, the routing table content of labeling apparatus d is:
| Project | Content |
| The first via by | Label eTrain_ID |
| Secondary route | Label fTrain_ID |
| 3rd route | Label gTrain_ID |
| 4th route | Empty |
When route entry content is empty, represent this route unavailable.
When marshaling is through routing configuration equipment, route data is also sent to labeling apparatus by routing configuration recognition of devices vahicles label, and labeling apparatus is stored in routing table after receiving route data.Train, often through a routing configuration equipment, namely receives a route data, and routing table refreshes once, to ensure the normal networking of this self-organizing network.
In the present embodiment, this network is the chain network of self-organizing, and this network characteristics has: node device adds at random, and network lifetime is indefinite; Its apparatus for network node is divided into three kinds: first-in-chain(FIC) equipment, intermediate equipment and last-of-chain equipment; In this network, information transmission is unidirectional, by last-of-chain equipment step by step forward final converging information at first-in-chain(FIC) equipment; Only have last-of-chain equipment initiatively can initiate information interaction in network, intermediate equipment or first-in-chain(FIC) equipment only can initiate information interaction initiatively after receiving the message again.
In the present embodiment, the node device of chain self-organizing network is without the need to possessing route exploration ability, and its networking (route generation, renewal) has been initiated by auxiliary equipment.When each node device is successively by auxiliary equipment, routing iinformation sends to node device to carry out routing update by auxiliary equipment.Owing to being backward from first-in-chain(FIC) to last-of-chain direction in this chain network, when last-of-chain is forward direction to first-in-chain(FIC) direction, only comprise its forward direction device address in each node device routing table, first-in-chain(FIC) equipment is arranged without routing table.In the present embodiment, the technology of the chain network obtained realizes simple, and routing update speed is fast, and node device function greatly simplifies, and power consumption effectively reduces.And general self-organizing network, its networking needs by each node device initiative recognition neighbor node feature, and by the protocol interaction generating network routing iinformation of complexity, actualizing technology is complicated.When network dimensioning is expanded, routing update efficiency will greatly reduce.
