The specific working process of the device is as follows:
1) the first control module 1410 is used to determine and process communication failure.
Generally, in order to ensure normal communication between node stations, 2 or more digital signal lines are arranged between two node stations capable of directly communicating; for example, digital signal lines a1 and a2 are provided between the node station a and another node station B, and if the first control module determines that the currently used digital signal line a1 has a failure and data transmission cannot be normally performed, a first switching instruction is generated to control the wiring unit 300 to perform automatic line switching, and the digital signal line a1 is replaced by a corresponding spare digital signal line a2, that is, a2 is used instead to perform data transmission between the node stations a and B.

For example, as for the present node station a and other node stations B, C, D in the digital signal line network, etc., digital signal lines a-B are provided between the present node stations a and B, digital signal lines a-C are provided between the present node stations a and C, and digital signal lines a-D are provided between the present node stations a and D; in practical applications, the node a needs to directly communicate with the node B and the node C, and does not directly communicate with the node D, the second control module 220 generates a corresponding second switching instruction, so that the corresponding communication port of the node a is respectively connected to the digital signal lines a-B and the digital signal lines a-C, and any communication port of the node a is guaranteed to be disconnected from the digital signal lines a-D, thereby meeting the actual communication requirements.
More specifically, the first control module 1410 includes a fault determination module 1411 and a line selection module 1412.
The fault determination module 1411 is configured to: judging whether data transmission faults exist in digital signal lines connecting the node station and other node stations according to the on-off state information acquired by the acquisition unit 1100, and if so, triggering the line selection module 1412;

For example, the failure determination module 1411 determines that the digital signal line a1 connecting the local node station a and another node station B has failed, the line selection module 1412 further determines which digital signal line between the local node station a and another node station B is available (idle and no failure), and if it determines that the digital signal line a2 is available, generates a second control command to control the corresponding communication port of the local node station a to be disconnected from a1 and connected to a2, thereby eliminating the communication failure between the node stations a and B.
Preferably, in the wiring device provided in the embodiment of the present application, the wiring unit adopts a 110 wiring unit, and is used for implementing connection between the communication port and the corresponding digital signal line through 110 wire bonding termination under the control of the main control unit.
More specifically, the 110 wire unit includes a mechanical linkage and a plug.
The plug connector comprises at least two plug connector male heads and at least two plug connector female heads; the male connectors and the communication ports of the node station are arranged in a one-to-one correspondence mode, the female connectors are arranged at one ends of the digital signal lines, and each male connector can be in matched butt joint with any female connector to realize connection of the corresponding communication port and the digital signal line; the connection between a certain communication port and any digital signal line can be realized by changing the matching relationship between the male connector and the female connector, namely the connection between a certain digital signal line and any communication port can be realized.
The mechanical linkage mechanism is used for realizing the butt joint of the corresponding plug connector male head and the corresponding plug connector female head and changing the matching relation of the plug connector male head and the plug connector female head under the control of the main control unit sending the switching instruction. Further, in order to minimize the volume of the actuator, the embodiment of the present application preferably employs a mechanical linkage mechanism having a structure shown in fig. 3 to simultaneously control a plurality of plug connectors.
As shown in fig. 5, the mechanical linkage provided by the embodiment of the present application includes a stepping motor 1, a retractable follow-up cable 2, and a fixed frame 3; wherein, step motor 1 has a plurality ofly, and every plug connector public head G and every plug connector female head M equally divide and do not dispose step motor 1, follow-up cable 2 and step motor 1 one-to-one, and the one end of follow-up cable 2 is connected with a plug connector public head G or plug connector female head M, and the other end is connected with corresponding step motor 1. The working principle is as follows: under the control of a switching instruction sent by a main control unit, the stepping motor 1 rotates forwards or backwards, so that a follow-up cable 2 connected with the stepping motor is driven to extend or shorten, and a male connector plug or a female connector plug connected with the follow-up cable 2 moves; through the coordination control of the two stepping motors 1, the corresponding butt joint or separation of the male connector and the female connector of the connector can be realized.
On the basis of the basic working principle, the phenomenon of collision is avoided for realizing the arbitrary matching and butt joint of the male connector and the female connector, and the mechanical linkage mechanism has the following characteristics:
1) the fixing frame 3 is a rectangular frame, the stepping motor 1 and the follow-up cable 2 for controlling the male connector are fixed on a first side of the rectangular frame, the stepping motor 1 and the follow-up cable 2 for controlling the female connector are fixed on a second side of the rectangular frame, and the first side is adjacent to the second side.
2) The motion tracks of all the male plug connectors (i.e. the telescopic tracks of the following cables 2 fixed on the first side of the fixed frame 3) are parallel to each other and are all positioned in a first plane S1; the motion tracks of all the plug connector female heads (namely the telescopic tracks of the follow-up cables 2 fixed on the second side of the fixed frame 3) are parallel to each other and are positioned in a second plane S2; the first plane S1 and the second plane S2 are parallel and do not coincide. For example, it can be set as: the motion tracks of all the plug connector male heads are parallel to the second edge, and the motion tracks of all the plug connector female heads are parallel to the first edge; the first plane S1 is located above the second plane S2, with a spacing such that: when the male connector and the female connector are positioned on the same vertical line of the first plane S1, the male connector and the female connector can be successfully butted.
In a mated condition as shown in FIG. 5, the male connector G1 mates with the female connector M2, and the male connector G2 mates with the female connector M1; because the motion tracks of the male plug-in connector heads G1 and G2 and the female plug-in connector heads M1 and M2 are respectively positioned on the parallel and non-coincident planes S1 and S2, the male plug-in connector heads G1 and M2 are butted and not blocked by M1, and the female plug-in connector head M1 can also be butted with G2 and not blocked by G1.
As can be seen from the above description, in the embodiment of the present application, the 110 wiring unit is used for wiring (i.e. performing connection between the communication port of the node station and the digital signal line), so that loss caused by the wiring unit to the communication line can be reduced to the maximum extent, and the line loss can be compensated in various ways, for example, the follow-up cable in the mechanical linkage mechanism uses a high-performance transmission cable with a "sticky structure" to maintain the distance between the cores in the cable movement, thereby ensuring consistency of "characteristic impedance" of the follow-up cable, and reducing the line loss.
In this embodiment of the application, the communication state information detected by the sampling unit may specifically include: whether each digital signal wire is connected with a communication port, whether data exists on the digital signal wire connected with the communication port, and whether the communication port of the node station can receive or send the data; the length of each follow-up cable in the mechanical linkage mechanism can be further included (the length can be used for judging whether the male connector and the female connector of the plug connector are in butt joint or not or judging whether a certain digital signal line is idle or not) and the like.
In addition, as shown in fig. 6, in the digital signal line remote wiring system provided in the fifth embodiment of the present application, the wiring device 1000 further includes, in addition to the acquisition unit 1100, the wiring communication unit 1200, the wiring unit 1300, and the main control unit 1400, the main control unit 1400 and/or the wiring communication unit 1200, which are respectively connected to:
an environment monitoring module 1500, configured to detect an environmental parameter of the node station, such as temperature monitoring, water immersion monitoring, and the like;
the power supply monitoring module 1600 is used for performing power supply management on the digital signal line intelligent wiring device, such as charge and discharge management, two-way power supply management, energy monitoring and the like of a storage battery for supplying power;
