3=3; Described current detection direction value can be set to D
0, D
1, D
2or D
3.In the embodiment of the present invention, initialized node P0, P1, P2, P3, P4 only represent relative position, do not limit one and are decided to be position relationship in Fig. 6.
Wherein in an embodiment, described current detection direction value is chosen as D
2=2, namely with the current detection direction value that the bottom data port of current detection node is initial.
With reference to Fig. 5, after the vector value of the neighbor node that initialization is connected with described current detection node and current detection direction value, be namely current detection node PX, D with P0
2for the information of damage node SP is sent to CPU by current detection direction value.Detailed process is as follows:
S3: judge that whether FPDP corresponding to the current detection direction value of described current detection node be normal; If so, S4 is performed; Perform S5 if not;
Namely the current detection direction value D of described current detection node PX is judged
2whether the FPDP that (below PX) is corresponding is normal.Judge that the whether normal method of FPDP can be, to the current detection direction value D with described current detection node PX
2the neighbor node that corresponding FPDP connects sends current feedback status request.
S4: the coordinate calculating the node that FPDP corresponding to described detection direction value connects, and node FPDP corresponding for described detection direction value connected is as current detection node; Perform S3;
Shown in composition graphs 5, if the FPDP corresponding with below current detection node is normal, then calculates the coordinate of the node be connected with this FPDP, and it can be used as current detection node, continue to perform S3; If the FPDP corresponding with below current detection node is abnormal, then perform S5, such as, when current detection node PX is node PZ, FPDP corresponding below it does not connect neighbor node or neighbor node disconnects (by damaging), then think that the FPDP corresponding with below current detection node is abnormal; The computational methods of the coordinate of the node be connected with this FPDP are calculated by the coordinate of current detection node and the relative coordinate of neighbor node that is connected with the current detection port of current detection node.Such as, if current detection node coordinate is (x1, y1), current detection port is D
2, the relative coordinate of the neighbor node be connected with the current detection port of current detection node is (0 ,-1), then the coordinate of the neighbor node be connected with the current detection port of current detection node is (x1, y1-1), and the rest may be inferred.
S5: revise described current detection direction value, current detection direction value=(current detection direction value+1) %4; I.e. current detection direction value=(D
2+ 1) %4, current detection direction value is D
3, namely current detection direction revises 90 ° counterclockwise.
S6: judge that whether FPDP corresponding to the current detection direction value of described current detection node be normal; If so, S7 is performed; If not, S8 is performed;
Namely judge that whether FPDP corresponding to current detection node PX (for node PZ) right normal, judge FPDP whether normally method can be, to the current detection direction value D with described current detection node PX
3the neighbor node that corresponding FPDP connects sends current feedback status request.
S7: the coordinate calculating the node that FPDP corresponding to described detection direction value connects, and node FPDP corresponding for described detection direction value connected is as current detection node; Revise described current detection direction value, current detection direction value=(current detection direction value+3) %4; Perform S6;
Shown in composition graphs 5, if FPDP corresponding to current detection node PX (for node PZ) right is normal, then calculate the coordinate of the node that FPDP corresponding to current detection node PX (for node PZ) right connects, and node FPDP corresponding for described detection direction value connected is as current detection node, now, in order to based on Edge check, revise described current detection direction value D
3, current detection direction value=(D
3+ 3) %4, current detection direction value becomes D
2, namely become again and detected direction value last time.And circulation performs S6.When circulating execution S6, the D of the node that FPDP corresponding with node PZ right in Fig. 5 connects
2in fact (below) FPDP does not have connected node, and namely in S6, the FPDP that the current detection direction value of described current detection node is corresponding is abnormal, now needs to perform S8.
S8: perform S5, until the connected node of current detection node is central processing unit.
Perform S5 ~ S8 according to above-mentioned steps circulation, until the connected node of current detection node is central processing unit, be about to the information transmission of damage node to central processing unit (CPU).It should be noted that, in Fig. 5, node SM is intermediate axle girder connection, and when node SM is damaged, the node on the left of node SM just loses with central processing unit and contacts, now then can not by node SM left node information transmission to central processing unit.Therefore, in other embodiments, according to the multiple central processing unit of the layout setting of meshed network, also multiple meshed network can be set in damage detection system, to obtain concrete node damage information more accurately.Fig. 5 interior joint SC is datum node, and it is connected with central processing unit, realizes the data communication bridge of other nodes and central processing unit in meshed network.When node SC is damaged, other all nodes all lose with central processing unit and contact.Therefore, in other embodiments, central processing unit can be connected with multiple node, guarantees that central processing unit and other nodes set up multiple data transmission channel.In Fig. 5 with node P0 for the nodal information of damage node SP is transferred to CPU (in Fig. 5 shown in solid line) based on Edge check by start node.Data transmission channel can be set up with the fastest speed, transmission damage nodal information based on Edge check.
The information of each damage node all can be sent to central processing unit based on the data transmission method of above-mentioned preferred embodiment by the data transmission method of each damage node of meshed network of the present invention when damaging.Central processing unit can be described to damage shape according to the information of each damage node, calculates damaged area, thus judges damage situation.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
