TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering wiring, in particular to a weak current engineering wiring method facilitating wiring adjustment. BACKGROUND

[0002] Weak current generally refers to direct current circuit or audio, video circuit, network circuit, telephone circuit, direct current voltage is generally within 36V, telephone, computer, television signal input (cable television circuit), audio equipment (output circuit) and other household appliances are weak current electrical equipment. Weak current wiring must use frequency division or exchange equipment to achieve sharing and intercommunication. The exchange equipment of the internal and external networks of the network is a router (for LAN) or a modem (for ADSL). The weak current circuit adopts star wiring, and the cable in the wiring box is left with a head of about 10 cm. If the connector is wrong, it can still be recovered.

[0003] With the development of intelligence, the application scenarios of weak current have expanded from traditional household simple telephone and cable television circuit to building automatic control system, security monitoring system, smart home network and other complex scenarios. The weak current system in these scenarios contains a large number of audio, video, network and other types of lines, and the requirements for line direction, density arrangement are more flexible due to different device interface positions and heights.

[0004] When wiring weak current, the regularity needs to be considered to facilitate wiring and subsequent maintenance and other operations. However, the traditional weak current wiring method is not convenient for adjusting wiring, and the comprehensive wiring capability is poor. SUMMARY

[0005] The present application relates to the technical field of engineering wiring, in particular to a weak current engineering wiring method facilitating wiring adjustment.

[0006] To achieve the above-mentioned purpose, the present application provides a weak current engineering wiring method facilitating wiring adjustment, comprising the following steps: Based on the construction drawing, go to the construction site to investigate, confirm the interface, calculate the wiring parameters, and plan the path; Based on the planned path, set the obstacle avoidance point and the turning point, install the bridge, and lay the pipe; Lay the cable to the bridge and the pipe, and arrange and fix the cable; Terminate the information socket and the distribution frame, and debug the circuit.

[0007] Among them, the specific way of going to the construction site to investigate based on the construction drawing, confirming the interface, generating the wiring parameters, and planning the path is: Based on the construction drawing to the construction site survey, confirm the interface; According to the regional function to expand the topological graph, calculate the wiring parameters, draw the weighted graph, and plan the path.

[0008] Among them, the wiring parameters include the distance between the connection points, the wiring width and the adjustment limit.

[0009] Among them, the drawing weighted graph standard is to adjust the difficulty according to the cost of 1 straight line segment, the cost of 3 turning segment and the cost of 5 floor segment, and the path with a cost ≤10 is preferred.

[0010] Among them, the specific way of laying cables to the bridge and the pipe is: Classify and arrange the cables, and paste the cable labels; Pull and lay the cables to the bridge and the pipe respectively; Arrange and fix the cables.

[0011] Among them, the debugging line includes using a cable tester to detect the on-off, crosstalk and attenuation of each information point to ensure that the parameters meet the standard; pulling each cable to check whether the signal is interrupted during adjustment.

[0012] Among them, the debugging line also includes simulating device displacement, adjusting the corresponding cable length, testing system linkage; switching the standby path to verify the normal signal transmission.

[0013] The weak current engineering wiring method of the application is convenient for adjusting the wiring, based on the construction drawing to the construction site survey, confirming the interface, calculating the wiring parameters, and planning the path; based on the planning path, setting the obstacle avoidance point and the turning point, installing the bridge, and laying the pipe; laying the cable to the bridge and the pipe, and arranging and fixing the cable; terminating the information socket and the distribution frame, and debugging the line. The method can automatically generate the optimal scheme of weak current engineering wiring by inputting relevant parameters, proposes quantitative requirements for cable spacing, and reserves adjustment space, which can independently adjust the pipeline wiring when the wiring needs to be changed in the future, and the adjustment is flexible, thereby solving the problem of inconvenient adjustment of traditional weak current wiring.

[0020] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, the embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0021] Please refer to Figs. 1 to 3 The present application provides a weak current engineering wiring method for facilitating wiring adjustment, comprising the following steps: S1 based on construction drawings to go to the construction site for survey, confirm the interface, calculate the wiring parameters, and plan the path; Specific method: S11 based on construction drawings to go to the construction site for survey, confirm the interface; In this embodiment of the invention, the construction drawings of the low-voltage system (including location diagrams and system diagrams) are brought to the site to verify the design locations of equipment such as information sockets, switches, and cameras one by one, and to mark any locations that do not match the actual locations (such as where changes in the wall structure prevent the socket from being installed). The locations of the power distribution box and cable trays are confirmed with the power construction team to ensure that the distance between low-voltage and high-voltage lines is ≥30cm (to avoid electromagnetic interference); the pipe routing is confirmed with the water supply and drainage and HVAC teams to avoid areas prone to moisture or temperature differences, such as under water pipes and near air conditioning vents. In areas requiring flexible adjustment, such as conference rooms and open office areas, 2-3 additional spare interface points are marked (such as wall-mounted recessed boxes), and "expandable and adjustable" is noted on the drawings.

[0022] S12 selects the topology graph based on the area function, calculates the wiring parameters, draws the weighted graph, and plans the path.

[0023] In this embodiment of the invention, the topology is selected based on the area function—a "star topology" (single-path independent adjustment) is used for the equipment room area, and a "bus topology" (adjustable via junction box branches) is used for the public corridor area. Cabling parameters are calculated: connection point spacing is calculated based on "cable bending radius ≥ 8 times wire diameter," Category 6 network cable spacing ≥ 40cm, fiber optic cable spacing ≥ 50cm; cabling width: 30% redundancy is reserved for cable tray / conduit capacity; for example, if a cable tray is designed to accommodate 20 network cables, a 26-cable capacity is selected; adjustment limits: the maximum pull-out length of each line segment is marked (e.g., the maximum adjustment length of a single line in a vertical cable tray is 15m). Nodes (equipment interfaces) and edge sets (cabinet paths) are marked in the CAD drawing, and the adjustment difficulty is marked as "straight line segment cost 1, turning segment cost 3, floor penetration segment cost 5," prioritizing paths with a cost ≤ 10.

[0024] S2 sets obstacle avoidance points and turning points based on the planned path, installs cable trays, and lays conduits; In this embodiment of the invention, sliding brackets are fixed with expansion bolts at the positions marked on the weighted diagram (spacing ≤ 2m). Horizontal cable trays maintain a 3‰ slope (for easy drainage), and each layer of vertical cable trays is equipped with an inspection port (1.5m high). Sliding partitions are installed inside the cable trays, divided into system zones (data - blue zone, security - red zone, voice - white zone). The partitions can slide left and right to adjust the zone width. A 5cm gap is maintained at the cable tray connections for easy disassembly and adjustment later. One cable traction pulley is installed every 3 layers inside the vertical cable tray to reduce friction during adjustment. The conduit diameter is selected according to the principle of "total cable cross-sectional area ≤ 40% of the conduit cross-sectional area," such as using a Φ20 conduit for 3 Category 6 network cables and a Φ25 conduit for 5 optical fibers. When bending PVC pipes, a heat bender is used, with a bending radius ≥ 10 times the outer diameter of the pipe, and no more than 2 bends per section of conduit. Steel pipes are connected with threaded joints and wrapped with PTFE tape to prevent loosening, facilitating disassembly and adjustment later. For concealed wiring in walls, a junction box (adjustable node) should be installed every 3 meters. The spacing between hanging points of conduits within the ceiling should be ≤1.5m, and the distance from power conduits should be ≥30cm. For bends: Install bends at corridor corners and near server racks, using rounded transition pieces instead of right-angle bends. Bend radius: ≥40mm for network cables, ≥50mm for fiber optic cables. Install a rotatable cable management device at each bend, allowing cables to slide and adjust along the device. For skip-floor obstruction: Use fire-resistant conduits (5cm above the floor slab) when passing through floors, with two pre-installed traction steel wires inside the conduit. Prioritize using spare cable trays in the low-voltage shaft for skip-floor adjustment via the floor distribution frame (FD) to avoid damaging existing wiring. Labeling: Affix yellow labels at bends and obstruction points, indicating "Adjustable Node" and the type of adjustable cable (e.g., "Adjustable only for shielded cables").

[0025] S3 lays cables to the cable tray and the conduit, and organizes and secures the cables; Specific methods: S31 sorts and organizes the cables and affixes cable labels; In this embodiment of the invention, cables are sorted by system, with data cables (network cables, fiber optic cables), security cables (camera cables, access control cables), and voice cables stacked separately to avoid confusion. Labeling: Waterproof labels are affixed to both ends of the cables, indicating "Floor-Area-Number-Type-Adjustment Limit" (e.g., "F1-Office Area-05: Category 6 Network Cable, Maximum Extension 8m"). The labels are 10cm from the ends, with one additional label added every 10m in between.

[0026] S32 pulls and lays cables to the cable tray and the conduit respectively; In this embodiment of the invention, for short-distance laying (≤20m): a smooth traction head is fitted onto the end of the cable (to avoid scratching the insulation layer); one person pushes the cable at the starting point, and another person gently pulls it at the end point, maintaining a constant speed to avoid bending the cable; when laying in a cable tray, a sliding cable organizer is used to return the cable to the corresponding section. For long-distance laying (>20m): when threading the cable through the conduit, the traction wire is first threaded into the conduit, and one end of the wire is tied with a cable traction head (the connection point is wrapped with tape to make it smooth); people pull synchronously, with one person assisting every 20m, and talcum powder is applied for lubrication when encountering bends; the traction force of optical fiber is ≤80N, and the traction force of twisted pair is ≤100N, and a tension gauge is used for real-time monitoring. Reserved length control: 0.5-1m is reserved at the equipment end (such as information sockets, switches), and it is lightly fixed with cable ties after coiling (the tightness should be such that it can be pulled out); 30cm is reserved at junction boxes and patch panels to facilitate later joint adjustments.

[0027] S33 organizes and secures the cables.

[0028] In this embodiment of the invention, the cable tray is organized as follows: Cable ties are used to secure the cables with the thicker wire at the bottom and the thinner wire at the top. The spacing between the ties is ≤50cm, and the tightness is such that the cables can move slightly (for easy adjustment). Sliding dividers are adjusted as needed to ensure that cables in each section do not cross. The conduit is inspected after installation using a cable tester to check for continuity and ensure there are no broken wires or short circuits. The cable identification and path correspondence are recorded.

[0029] S4 terminal blocks are used to connect information sockets and patch panels for line testing.

[0030] In this embodiment of the invention, the information socket is terminated as follows: Wire stripping: Pull the cable out of the junction box, strip off the outer sheath (length ≤15mm) to expose 4 pairs of wires, and avoid damaging the wire cores. Module termination: According to the 568B standard (white-orange-orange-white-green-blue-white-blue-green-white-brown-brown), press the wire pairs into the corresponding slots of the modular information module and fix them with a punch-down tool to ensure good contact. Panel installation: Insert the module into the openable dustproof panel. After the panel is fixed to the bottom box, leave a 1mm gap between the panel and the wall (for easy disassembly and adjustment later).

[0031] Patch panel termination Cable organization: Classify the cables in the computer room according to their labels, and use cable management rings to organize them. Group 24 cables into one group, corresponding to one 24-port patch panel. Termination procedure: According to the patch panel markings (T568B), press each wire pair into the terminal one by one, fix it with crimping pliers, and cut off any excess wire cores; when terminating the fiber optic patch panel, use a fiber optic fusion splicer (fusion loss ≤0.03dB) and cover it with a protective sleeve. Patch cable connection: Use pluggable Cat6 patch cables to connect the patch panel and the switch. Select the patch cable length according to "actual distance + 0.5m" to avoid being too short to adjust or too long and messy.

[0032] Standalone testing: Use a cable tester to check the continuity, crosstalk, and attenuation of each information point to ensure that the parameters meet the standards; pull each cable (according to the marked adjustment limits) to check whether the signal is interrupted during adjustment (such as whether the network ping value is stable and whether the camera image is smooth).

[0033] System integration testing: Simulate equipment relocation (such as adjusting workstations in the office area), adjust the corresponding cable lengths, test system interoperability (such as whether the monitoring system triggers recording after the access control card is swiped); switch to backup paths (such as enabling the backup path with cost 12 in the weighted graph when the main path fails), and verify that the signal transmission is normal.

[0034] The above-disclosed embodiments are merely preferred embodiments of a low-voltage engineering wiring method that facilitates the adjustment of wiring, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
