1) Complete the judgment and processing of the communication failure through the first control module 1410 .

Usually, in order to ensure the normal communication between each node station, two or more digital signal lines are set between two node stations that can communicate directly; for example, there is a For the digital signal lines A1 and A2, if the first control module determines that the currently used digital signal line A1 is faulty and data transmission cannot be performed normally, it will generate a first switching instruction, control the wiring unit 300 to perform automatic line switching, and transfer the digital signal The line A1 is replaced by the corresponding spare digital signal line A2, that is, the data transmission between the node stations A and B is realized by using A2 instead.

For example, the failure judging module 1411 determines that the digital signal line A1 connecting the local node station A and another node station B is faulty, and the line selection module 1412 further judges which digital signal line between the local node station A and another node station B line is available (idle and without failure), if it is determined that the digital signal line A2 is available, a second control instruction is generated to control the corresponding communication port of the node station A to disconnect from A1 and connect to A2, thus eliminating the need for node station A Communication failure with B.

Preferably, in the wiring device provided in the embodiment of the present application, the wiring unit adopts a 110 wiring unit, which is used to realize the connection between the communication port and the corresponding communication port through 110 wiring termination under the control of the main control unit connection of digital signal lines.

More specifically, the wiring unit 110 includes a mechanical linkage mechanism and a connector.

The connector includes at least two connector males and at least two connector females; the male connectors are set in one-to-one correspondence with the communication ports of the node station, and the female connectors Set at one end of the digital signal line, each connector male head can be matched with any connector female head to realize the connection between the corresponding communication port and the digital signal line; by changing the connector male head and the connector female head The matching relationship of the head can realize the connection between a certain communication port and any digital signal line, that is, the connection between a certain digital signal line and any communication port.

The mechanical linkage mechanism is used to realize the docking of the corresponding plug-in male head and the plug-in female head and change their matching relationship under the control of the switching command sent by the main control unit. Further, in order to minimize the volume of the actuator, the embodiment of the present application preferably has a mechanical linkage mechanism with the structure shown in FIG. 3 to simultaneously control multiple connectors.

As shown in Figure 5, the mechanical linkage mechanism provided by the embodiment of the present application includes a stepper motor 1, a retractable follow-up cable 2 and a fixed frame 3; wherein, there are multiple stepper motors 1, and each connector The male head G and the female head M of each connector are respectively equipped with a stepping motor 1, and the follower cable 2 corresponds to the stepping motor 1 one by one, and one end of the follower cable 2 is connected to a male connector G Or the female connector M of the connector is connected, and the other end is connected with the corresponding stepping motor 1. Its working principle is: under the control of the switching command sent by the main control unit, the stepping motor 1 performs forward rotation or reverse rotation, thereby driving the follow-up cable 2 connected to it to extend or shorten, and then make the follow-up cable 2 The male connector or the female connector connected by the cable 2 moves; through the coordinated control of the two stepping motors 1, the corresponding docking or separation of the male connector and the female connector can be realized.

On the basis of the above-mentioned basic working principle, in order to realize the arbitrary matching and docking of the male connector and the female connector and avoid the phenomenon of "crashing", the mechanical linkage mechanism has the following characteristics:

1) The fixed frame 3 is set as a rectangular frame, and the stepper motor 1 and the follow-up cable 2 used to control the male head of the connector are fixed on the first side of the rectangular frame, and are used to control the stepping of the female head of the connector The motor 1 and the follower cable 2 are fixed on the second side of the rectangular frame, and the first side is adjacent to the second side.

2) The motion tracks of the male connectors of all connectors (that is, the telescopic trajectory of the follower cable 2 fixed on the first side of the fixed frame 3) are parallel to each other and are located in the first plane S1; the female connectors of all connectors The trajectory of the movement (that is, the telescopic trajectory of the follower cable 2 fixed on the second side of the fixed frame 3) is parallel to each other and located in the second plane S2; the first plane S1 and the second plane S2 are parallel and do not overlap . For example, it can be set as follows: the motion trajectories of all the male connectors are parallel to the second side, and the motion trajectories of all the female connectors are parallel to the first side; the first plane S1 is located on the second plane Above S2, the spacing ensures that: when the male connector and the female connector are located on the same vertical line of the first plane S1, they can just be successfully docked.

In a docking state as shown in Figure 5, the male connector G1 is docked with the female connector M2, and the male connector G2 is docked with the female connector M1; since the male connectors G1 and G2 The motion trajectories of the female connectors M1 and M2 are respectively located on the parallel and non-overlapping planes S1 and S2, so the male connector G1 and M2 are docked without being blocked by M1, and the female connector M1 can also be connected to G2 docks and is not blocked by G1.

It can be seen from the above description that the embodiment of the present application uses the 110 wiring unit for wiring (that is, the connection between the communication port of the node station and the digital signal line), which can minimize the loss caused by the wiring unit to the communication line , and the line loss can be compensated in various ways. For example, the follower cable in the mechanical linkage mechanism adopts a high-performance transmission cable with a "sticky structure" to maintain the distance between the cores in the cable movement, thereby It ensures the consistency of the "characteristic impedance" of the follower cable and reduces line loss.

In the embodiment of the present application, the communication status information detected by the sampling unit may specifically include: whether each digital signal line is connected to the communication port, whether there is data on the digital signal line connected to the communication port, whether the communication port of the node station can Receive or send data; it can also include the length of each follower cable in the mechanical linkage mechanism (it can be used to judge whether the male head of the connector is connected to the female head of the connector, or whether a certain digital signal line is free), etc.
