Specific embodiment
Below in conjunction with attached drawing, embodiments of the present invention is further illustrated.
As shown in Figure 1, in a kind of network-building method of chain communication network of the present invention and device embodiment, networking side Method includes the following steps:
Whether step S11 receives the information that network element is sent, if so, performing next step;Otherwise.Repeat this step Suddenly.In the present embodiment, one for being formed or being formed after train marshalling list with the vehicle carried electronic label on a rail vehicle It is illustrated for chain communication network.In the present embodiment, the communication network is in addition to the above-mentioned electronics on each vehicle Outside label, the first equipment of the row being separately mounted on headstock and the Train End Equipment mounted on last vehicle of train are further included;These equipment and Electronic tag forms a chain communication network at least in physical arrangement according to the spread pattern of rail vehicle;It is practical On, after the method in using the present embodiment, which also forms a chain network in routing or in logic.Its In, above-mentioned row head equipment is first-in-chain(FIC) equipment, and Train End Equipment is last-of-chain equipment, and vehicle carried electronic label positioned there between is then According to the physical location of vehicle where it in train be endowed with its physical location same logical location, so as to form a chain Type communication network.In the present embodiment, above-mentioned multiple electronic tags being sequentially located between first-in-chain(FIC) equipment and last-of-chain equipment(I.e. should The network element of communication network)It is respectively provided with different network address(The identification code of the network address including the electronic tag or ID codes).When above-mentioned train marshalling list is completed and is advanced, the all-network unit in above-mentioned chain communication network(It is set including row head Standby and Train End Equipment)The position arranged according to it, headed by the first-in-chain(FIC) equipment(I.e. by the first-in-chain(FIC) equipment), lead to successively Cross routing setting equipment, routing setting equipment be used for by chain grid cell carry out information exchange and will be current By network element information be sent to by network element;I.e. when train sets equipment by above-mentioned routing, Network element on train can be activated, and carry out data interaction with routing setting equipment, on the one hand receive from routing setting The data of equipment(The data are to set the network element parameter of equipment by routing before the vehicle), on the other hand upload certainly Oneself parameter, including device type and address.In this way, when the rolling stock of train sets equipment by above-mentioned routing, each Network element knows the address of the network element of the front, that is, has arrived the routing forwarding address of this unit, constitutes one The communication network of a chain.In this step, exactly judge whether to receive the network element transmission on rail vehicle to come Data, when being not received by any data, repeat this step, continue waiting on train network element transmission data; When data is received, next step is performed.
Step S12, which is obtained, represents device type and the data of device address in above- mentioned information:In this step, to receiving To data handled, obtain information therein.In general, on above-mentioned electronic tag or the first equipment of row or Train End Equipment The data of biography are all transmitted in the form of data packet.After such data packet is received, choosing is needed to unpack it Processing, obtains data content therein;Then it is taken out again in the content of the designated position of these obtained data, with regard to phase can be obtained The information of pass, for example, the type of equipment and its network address.In this step, the expression of acquirement network element transmission net The device type of network unit and the data of network address, the network address are typically the equipment or electronic tag in the present embodiment Identification code or ID codes.
Step S13 judge the network element whether first-in-chain(FIC) equipment, if so, performing step S14;Otherwise step S15 is performed. In the present embodiment, for network element and first-in-chain(FIC) equipment, although being all regarded as the component part of network, When it is by above-mentioned routing setting equipment, the mode of processing is different.This is because first-in-chain(FIC) equipment is exactly the first equipment of row, On the headstock of train, in train operation, it is to set equipment by routing earliest in entire communication network to arrange first equipment Network components, in the present embodiment have special status.In this step, by obtaining the equipment class in data Type come judge transmit data come whether row head equipment.In the present embodiment, the device type for arranging first equipment is one prior The code of setting, any part being different from the network.When the device type in the data for finding to receive is that this is prior During the code of setting, just can determine that the equipment for uploading data is the first equipment of row.
The first inventory that the network element addresses are put into blank by step S14 is the first:In this step, due to having sentenced Disconnected is being the first equipment of row with route setting equipment progress data interaction, and for communication network in this present embodiment, The equipment can not be interacted actively with other network element, in fact, in communication network in the present embodiment, only be arranged Tail equipment can actively initiate data communication;Network element between Train End Equipment and the first equipment of row will not be initiated actively Communication is only after the data or instruction that other network element sends are received, turns according to the routing inventory of oneself storage Hair.So in the present embodiment, arrange first equipment there is no routing table, routing configuration equipment also without to above-mentioned row head equipment into Row routing configuration, and be only that its address is recorded in the first inventory.But since the first equipment of row is in whole network First by the network element of above-mentioned routing configuration equipment, it is therefore desirable to which its address is recorded in one new or blank the In one inventory, to be different from the first inventory obtained from routing setting equipment is before configured other communication networks, together When, it would be desirable to the address for arranging first equipment is placed on to the starting position of first inventory.So in this step, in record first-in-chain(FIC) Before device address to the first inventory, the inventory is formatted, is left before that may be present in the first inventory of elimination The data got off, so that it becomes blank.After having performed this step, return to step S11.
Step S15 sends existing first inventory to the network element:In this step, due to it is determined that currently just It is not the first equipment of row close the book routing configuration equipment progress information exchange, shows that arranging first equipment has passed through, in this way, first It has been described in inventory all in this compartment(Or the identification electronic tag installed on this compartment)All-network unit before Address, the arrangement of the network element addresses in this first inventory has certain rule, is more proximate to the vehicle-mounted of this compartment Electronic tag address, first position of the position in the top of the inventory, the first inventory, record is close to this vehicle Compartment and the address of the vehicle carried electronic label on this compartment preceding carriage.So in this step, which is sent To the above-mentioned network element interacted with routing setting equipment(Electronic tag or Train End Equipment)In.Network element receives After the first inventory sent to the routing setting equipment, stored as routing table;The network element is carrying out net According to the routing table its address of sequential selection from top to bottom as default address when network communicates.
Step S16 moves the data in existing first inventory, and the address of the network element is put into existing first inventory First place obtains the first new inventory:In this step, due to have been achieved with it is current by network element type and ground Location, and in order to enable next network element can obtain its routing address, the network element addresses that will be obtained is needed to be added to In above-mentioned first inventory.For this reason, it may be necessary to first move the data content in existing first inventory, first position of the first inventory is vacated Put for place by network element address, then the address is stored in above-mentioned position again.Specifically, at this In step, first by the data with existing content of current first inventory to the rear of the inventory or lower section move integrally address away from From its inventory starting position is made to vacate the memory space that can accommodate a device address data;It then again will be currently available Device address is recorded the above-mentioned of the first inventory and vacates in space, obtains new current first inventory.This step is performed Afterwards, return to step S11.
In this way, according to above-mentioned steps, when train is by routing setting equipment, above-mentioned steps are repeated continuously, and are often passed through One vehicle, the part being carried out in an above-mentioned steps or above-mentioned steps.In this way so that each vehicle carried electronic label and row Tail equipment can accurately obtain its route list, be configured so as to fulfill the logic of the chain communication network, realize networking.
In the present embodiment, above-mentioned routing device can be multiple, and multiple routing devices are separately positioned on different location Station rail side;Train refreshes its routing table again when setting equipment by a routing every time according to above-mentioned steps.In addition, It, will when chain grid cell such as finds that its address routeing in inventory is not responded in communication process after network organizing The address, which is route by it in inventory, to be deleted or is unreachable to the address mark for routing.
In the chain communication network of the present embodiment, the communicating node device at both ends is referred to as first-in-chain(FIC) equipment and last-of-chain is set It is standby, it is different from intermediate each communicating node device.The transmission of information is initiated from last-of-chain equipment in the network, is gradually converged to First-in-chain(FIC) equipment.Other than first-in-chain(FIC) equipment, there are a routing table, records in each communicating node device in the chain network All neighbor node device addresses for receiving the equipment and sending information, can be referred to as route entry, these route entries difference Preferred routing, secondary routing are noted as by, third routing etc..
When the node device needs to send message, route entry address is selected headed by default objects address, if preferred routing is not It can use(I.e. destination address equipment is without response, communication failure)It then attempts the address of route entry to be selected to communicate using secondary, locate successively Reason.
If route table items are empty, which cannot actively initiate information exchange, but can respond the message received and ask It asks.Routing table is not present in first-in-chain(FIC) equipment, the equipment only can response message, and cannot actively initiate information exchange.
In the present embodiment, when a chain communication network is got up by temporal organization, each communication node in network is set Standby to be required to obtain current recent route information, which can really complete networking, realize the transmission and interaction of information. For this purpose, current network routing letter is provided for each communication node in chain communication network in the present embodiment using routing configuration equipment Breath realizes effective networking between node.
