In one embodiment, the step S1 includes:

S11: a node connected by a data port corresponding to a preset detection direction value of the damaged node is used as a current detection node, and the current detection node acquires information of the damaged node;

S12: Initialize a vector value of a neighbor node connected to the current detection node and a current detection direction value;

S13: determining whether the data port corresponding to the current detection direction value of the current detection node is normal; if yes, executing S14; if not, executing S15;

S14: The current detection node sends the information of the damaged node to the node connected to the data port corresponding to the current detection direction value of the current detection node, and calculates the coordinates of the node connected to the data port corresponding to the current detection direction value, and Determining the node connected to the data port corresponding to the detection direction value as the current detection node; executing S13;

S15: Correct the current detection direction value, the current detection direction value=(current detection direction value+1)%4;

S16: determining whether the data port corresponding to the current detection direction value of the current detection node is normal; if yes, executing S17; if not, executing S18;

S17: Calculate coordinates of a node connected to the data port corresponding to the current detection direction value of the current detection node, and use a node connected to the data port corresponding to the current detection direction value of the current detection node as a current detection node; The current detection direction value, the current detection direction value = (current detection direction value +3)%4; execute S16;

S18: Execute S15 until the current detection node connection node is a central processing unit.

In one embodiment, in the step S11, the information of the damaged node includes a relative coordinate value and a direction value of the damaged node calculated based on coordinates of a certain node in the node network.

Specifically, in FIG. 6, it is assumed that the node SP is a damaged node, and the preset detection direction is a certain direction adjacent to the damaged node SP. The embodiment of the present invention selects P0 (that is, the data port under the damaged node SP). The connected node) acts as the current detection node. Of course, it is also possible to select a node that is connected to the data port in the other direction of the node SP as the current detection node. It can be understood that each node of the node network communicates with the neighbor node by default, and reports its status to the neighbor node. Therefore, the current detecting node detects that its neighbor node is damaged (that is, requests its neighbor node to send feedback information. When there is no feedback, it is ready to send the damaged node as the current detection node. Therefore, the current detection node before initialization defaults to a normal node. Get the coordinate value P0=(x, y) of the current detected node.

In one embodiment, in step S12, the vector value of the neighbor node is a preset relative coordinate value of a neighbor node connected to the port, and the current detection direction value is a preset location. A relative position value of a relative position value of a neighbor node currently connected to the detection node.

Specifically, referring to FIG. 7, in the step S12, the current detecting node sets four data ports, and if the coordinate value of the current detecting node P0 is P0=(x, y), it is connected with the data port above the current detecting node. The relative coordinate value of the neighbor node P1 is V0=(0, -1), and the relative position value of the neighbor node P1 connected to the data port above the current detection node is D0=0; and is connected to the left data port of the current detection node. The relative coordinate value of the neighbor node P2 is V1=(-1, 0), and the relative position value of the neighbor node P2 connected to the left data port of the current detection node is D1=1; the neighbor connected to the data port below the current detection node The relative coordinate value of the node P3 is V2=(1,0), the relative position value of the neighbor node P3 connected to the data port above the current detection node is D2=2; and the neighbor node P4 connected to the right data port of the current detection node. The relative coordinate value of the neighboring node P4 connected to the left data port of the current detecting node is D3=3; the current detecting direction value can be set to D0, D1, D2. Or D3. The nodes P0, P1, P2, P3, and P4 initialized in the embodiment of the present invention represent only relative positions, and are not necessarily limited to the positional relationship in FIG. 6.

In one embodiment, the current detection direction value is selected as D2=2, that is, the current detection direction value of the current detection node is the initial detection direction value.

Referring to FIG. 6 , after initializing the vector value of the neighbor node connected to the current detection node and the current detection direction value, the information of the damaged node SP is sent to the CPU by using P0 as the current detection node PX and D2 as the current detection direction value. The specific process is as follows:

That is, it is determined whether the data port corresponding to the current detection direction value D2 (below PX) of the current detection node PX is normal. The method for determining whether the data port is normal may be that the current feedback status request is sent to the neighbor node connected to the data port corresponding to the current detection direction value D2 of the current detection node PX.

S14: The current detection node sends the information of the damaged node to the node connected to the data port corresponding to the current detection direction value of the current detection node, and calculates the coordinates of the node connected to the data port corresponding to the detection direction value, and the Detecting the node connected to the data port corresponding to the direction value as the current detection node; executing S13;

As shown in FIG. 6, if the data port corresponding to the current detection node is normal, the coordinates of the node connected to the data port are calculated, and the current node is regarded as the current detection node, and S13 is continued; if it is corresponding to the current detection node If the data port is abnormal, the S15 is executed. For example, when the current detection node PX is the node PZ, the corresponding data port below the node is not connected to the neighbor node or the neighbor node is disconnected (destroyed), and the data port corresponding to the current detection node is considered as Not normal; the calculation method of the coordinates of the node connected to the data port is calculated by the coordinates of the current detection node and the relative coordinates of the neighbor nodes connected to the current detection port of the current detection node. For example, if the current detected node coordinates are (x1, y1), the current detection port is D2, and the relative coordinates of the neighbor nodes connected to the current detection port of the current detection node are (0, -1), then the current detection node is current. The coordinates of the neighbor nodes connected to the detection port are (x1, y1-1), and so on.

S15: Correct the current detection direction value, the current detection direction value=(current detection direction value+1)%4; that is, the current detection direction value=(D2+1)%4, and the current detection direction value is D3, that is, current detection The direction is corrected counterclockwise by 90°.

That is, it is determined whether the data port corresponding to the right of the current detection node PX (for example, the node PZ is normal) is normal, and the method for determining whether the data port is normal may be a data port corresponding to the current detection direction value D3 of the current detection node PX. The connected neighbor node sends a current feedback status request.

S17: Calculate coordinates of a node connected to the data port corresponding to the detection direction value, and use a node connected to the data port corresponding to the detection direction value as a current detection node; correct the current detection direction value, and the current detection direction value= (current detection direction value +3)%4; execute S16;

As shown in FIG. 6 , if the data port corresponding to the right side of the current detection node PX (taking the node PZ as an example) is normal, the coordinates of the node connected to the data port corresponding to the right side of the current detection node PX (taking the node PZ as an example) are calculated. And the node connected to the data port corresponding to the detection direction value is used as the current detection node. At this time, in order to detect the current detection direction value D3 based on the edge detection, the current detection direction value=(D3+3)%4, The current detection direction value becomes D2, that is, it changes back to the last detection direction value. And loop through S16. In the loop execution S16, the D2 (lower) data port of the node connected to the data port corresponding to the right side of the node PZ in FIG. 6 does not actually have a connection node, that is, in S16, the current detection direction value of the current detection node corresponds to The data port is abnormal. You need to execute S18.

S18: Execute S15 until the connection node of the current detection node is a central processing unit.

According to the above steps, S15~S18 are cyclically executed until the connection node of the current detection node is a central processing unit, and the information of the damaged node is transmitted to the central processing unit (CPU). It should be noted that, in FIG. 6, the node SM is an intermediate bridge node. When the node SM is damaged, the node on the left side of the node SM loses contact with the central processor, and at this time, the node information of the node SM cannot be transmitted. To the central processor. Therefore, in other embodiments, multiple central processors may be set according to the layout of the node network, or multiple node networks may be set in the damage detection system to obtain specific node damage information more accurately. In Figure 6, the node SC is a reference node, which is connected to the central processing unit to implement a data communication bridge between other nodes in the node network and the central processing unit. When the node SC is corrupted, all other nodes lose contact with the central processor. Thus, in other embodiments, the central processor can be connected to multiple nodes to ensure that the central processor establishes multiple data transmission channels with other nodes. In FIG. 6, node P0 is used as an initial node to transmit node information of the damaged node SP to the CPU based on edge detection (shown by a solid line in FIG. 6). Based on the edge detection, the data transmission channel can be established at the fastest speed, and the damaged node information is transmitted.

The data transmission method of each of the damaged nodes in the node network of the present invention can transmit the information of each damaged node to the central processor based on the data transmission method of the above preferred embodiment. The central processor can depict the damaged shape according to the information of each damaged node, calculate the damaged area, and judge the damage.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the patents of the present invention. Any equivalent structure or equivalent flow transformation made by the specification and the drawings of the present invention may be directly or indirectly applied to other related The technical fields are all included in the scope of patent protection of the present invention.
