                    Reference for the design concept of weak current room wiring

The reference for the design concept of weak current room wiring is crucial for ensuring the efficient and stable operation of the entire weak current system. At the beginning of the design process, it is necessary to conduct in-depth analysis of various factors such as the spatial layout, equipment configuration, and functional requirements of the weak current room to formulate a scientific and reasonable wiring design plan.

In terms of spatial layout, the weak current room should be located as close as possible to the information convergence center to facilitate data transmission and exchange. Considering the heat dissipation and maintenance requirements of the equipment, the spatial layout within the electrical room should be reasonably planned to ensure sufficient cooling space and maintenance channels between the equipment.

In terms of equipment configuration, appropriate weak current equipment such as switches, routers, servers, etc. should be selected based on actual needs, and the compatibility and scalability of the equipment should be considered. In addition, attention should be paid to the placement of the equipment to facilitate the laying of the wiring and the connection of the equipment.

In terms of functional requirements, the wiring design of the weak current room should meet various functional requirements such as data transmission, voice communication, and video surveillance. During the design process, the transmission characteristics and interference issues of various signals should be fully considered, and appropriate wiring types and connection methods should be adopted to ensure the stable transmission of signals.

To enhance the security and reliability of the weak current system, the wiring design should also consider measures such as lightning protection, fire prevention, and anti-interference. For example, shielded cable can be used to reduce the impact of electromagnetic interference, lightning arresters can be installed to prevent damage to equipment from lightning, and fire protection equipment can be configured to prevent the occurrence of fires. The reference for the design concept of weak current room wiring needs to comprehensively consider various factors such as spatial layout, equipment configuration, functional requirements, and safety measures. Only by fully considering and scientifically planning can the weak current system operate efficiently and stably, providing a strong guarantee for the enterprise's information construction. Zinc conduit, metal expansion bolts, metal flexible hose. Other materials, plastic expansion tube, machine screws, flat washers, spring washers, terminal blocks, drills, solder, flux, insulating tape, plastic tape, various connectors, etc. Tools and equipment, electric drills, impact drills, ladders, levels, lines, plummet, wire cutters, wire strippers, screwdrivers, electric soldering irons, flat-head screwdrivers, cross-head screwdrivers, needle-nose pliers, offset pliers, 250V megohmmeter, 500V megohmmeter.

Construction conditions, the interior decoration of the management building should be completed, doors, windows, and door locks should be fully assembled and complete. The wiring and cable trenches, conduits, boxes, and boxes in the management room, weak current shafts, other public parts within the building and the periphery should be completed. The positions of all reserved holes, embedded parts, the diameter of the pipe, the laying position of the pipeline, etc. should all comply with the design and construction requirements.

Operation methods, pipe pre-burial, refer to the content of the pipe pre-burial standard. Installation of controller boxes, the board of the box body and the frame should be in close contact with the building surface. It is strictly prohibited to weld the box body and the pre-buried pipe opening with electric welding or gas welding. The general installation position of the controller box depends on the design, and when there are no specific requirements, it is advisable to install it in a less visible or safer place to prevent malicious damage. The AC power supply of the controller box should be laid separately and must not be threaded in the same pipe as the signal lines and low-voltage DC power lines. When installing a wall-mounted controller box, find the elevation and drill a hole, embed the expansion bolt for fixation. The back plate of the box should be flush with the wall surface, and its height should be in accordance with the design requirements.

Cable laying, the laid cables should be arranged neatly, not twisted, and the crossings should be minimized. In the case of multiple cables being threaded into the pipe, the cables should not be twisted with each other, and there should be no joints in the pipe. Joints must be connected at the junction box (box) and from the controller box to the ceiling, the wiring should be protected by adding a sleeve buried in the wall or using an iron pipe to improve the anti-theft performance of the security system. Both ends of the laid cables must be marked, and the shielding layer of the shielded cable must be reliably grounded at one end.

Terminal equipment installation: During the installation of terminal equipment, it is necessary to cooperate with relevant professionals to make holes on the door frame and door panel. The installation positions of terminal equipment such as card readers, exit buttons, electric locks, and electromagnetic locks should comply with the design and product specifications. If there are no special requirements, the installation height of card readers and exit buttons should be 1.4m, and the distance from the door frame should be 0.1m. The installation height of electric locks should be 1.1m.

Terminal equipment installation: The installation of card readers should be close to the wall, with no gaps around it, and should be firmly installed. All accessories should be complete. Generally, the card reader is directly fixed on the concealed bottom box using special machine screws. Pay attention to ensuring a firm and reliable fixation to keep the panel upright. According to the wiring requirements specified in the design and product manual, connect the exposed wires in the box to the terminals of the card reader. Before installing electromagnetic locks and electric locks, check whether the specifications and models of the locks are suitable for their installation positions, heights, types of doors, and opening directions. Installation of electromagnetic locks: First, install the fixing plate and backing plate of the electromagnetic lock on the door frame and door panel respectively. Then, push the electromagnetic lock into the slot of the fixing plate and fix the screws. Connect the wires according to the diagram. For metal door frames, install the electric locks on the inside of the door frame, and the wires can be laid along the door frame using a soft plastic tube and enter the junction box at the top of the door frame. For wooden door frames, install the junction box and steel pipe on the outside of the door frame of the electric lock.

Equipment wiring and debugging: Before wiring, re-test the insulation between the wires and ground again. For equipment in the machine room, connect each device using dedicated wires. Press the wire ends of each branch line well, and the equipment and shielding wires should be well connected to the protective ground wire. The grounding resistance should be jointly grounded, and the value should not exceed 1Ω. During wiring, strictly follow the wiring diagram for connection, and then check again until it is confirmed to be correct. Connect the system management host, UPS power supply, printer and other equipment according to the design drawings and product manuals. Install the access control system management software on the system management host and perform initialization settings. Test the various functions of the system software according to the operation steps in the system software manual.

Finished product protection: During the installation of terminal equipment, pay attention to keeping the ceiling and walls clean. During the work of other trades, be careful not to damage the system equipment. In the machine room, take measures to prevent dust, moisture, pollution and water, to prevent damage to the equipment and loss of components. To prevent damage to the equipment and loss of components, promptly close the doors, lock them and assign a person to be responsible.

Quality issues to be noted: The connection between equipment and main lines or between main lines and terminals is not firm; promptly check and tighten the loose parts. When using shielded cables, the outer copper mesh should not touch the core wire; according to the requirements, the outer copper mesh should be separated from the core wire, and special attention should be paid to the pressing. When welding, do not contaminate the non-welding parts. After welding, promptly wipe off the welding oil with cotton wool (cloth strip). Due to the ungrounded shield wire or equipment, interference will occur. Press the shield wire and the ground wire of the equipment firmly as required.
