1. Îndeksan Girîng ya Têkêşên Kable
1.1 Têkêşên Rûhat û Naverok
Têkêş bike li rûhati kable (bê bigerkêji, derik, deforme, an guhertina rang). Bepike ku rûhat be hesas, plat û kêfî (bê kefî ji performansa û dema xizmetê werde hatine negatif). Navber bike uniformitya gav kable bikin da ku nabe problemên resistance an attenuationi sinyalê ji her dikêna wire. Her welat bike ku naverok (type, specification, manufacturer, production date, etc.) be şîn û rast, ku bêrbarîn bêtekîn bêrbarîn di serçem û operasyon de.
1.2 Têkêşên Connectivite
Bikarbehn testaran profesyonel (e.g., Time Domain Reflectometer, TDR) bi têkêşên test signals ji pointên access (data sockets, camera interfaces) derveya cihazên central, têkêş bike li transmission integrity. Ji bo binînên mezin, planên test partîyon bike, evaluate both physical connections and signal attenuation. Her welat bike adaptability of cables to new devices and system upgrades.
1.3 Têkêşên Performans Elektrîk
Test bike resistance characteristics (measure DC resistance to avoid excessive energy loss and weak signals), capacitance coupling (ensure stable independent signal transmission; abnormalities cause network interference), and attenuation (use attenuation measurement to check long-distance signal loss), ensuring electrical parameters meet communication needs.
1.4 Uzunî û Matching Impedance Characteristic
Determine cable length per design specifications (excessive length causes signal attenuation; insufficient length leads to wiring failures). Characteristic impedance must match devices to avoid signal reflection (causing return loss and degraded network performance), especially critical in intelligent building high-speed networks.
2. Problems û Risks Common
2.1 Inaccurate or Blurred Identification
Wrong identifications disrupt connections (e.g., server cables misconnected to wrong departments), affecting operations. Blurred identifiers increase troubleshooting time, reducing system availability.
2..2 Connectivity Failures
Connectivity issues interrupt information exchange (e.g., hotel guest-front desk, restaurant-kitchen data transmission), causing poor user experience, security blind spots, and office inefficiencies, threatening normal building operations.
2.3 Electrical Performance Deviations
Abnormal parameters (resistance, capacitance, inductance, impedance) cause signal attenuation, network fluctuations (packet loss, latency), electromagnetic interference (affecting device operation), and even endanger safety systems (fire alarms, elevators), leading to severe consequences.
2.4 Length and Impedance Disorders
Excessive cable length worsens signal attenuation (e.g., long office network cables slow networks and cause packet loss). Mismatched characteristic impedance causes signal reflection, interfering with intelligent controls (flickering lights, unstable air conditioning), increasing energy consumption and equipment wear, and potentially paralyzing system functions.
3. Response Measures and Optimization Suggestions
3.1 Full-Lifecycle Identification Management
Develop identification standards (e.g., commercial building data cables coded with "D" plus floor/room info). Use professional equipment and durable materials; recheck during wiring and update identifiers for system upgrades, improving operation efficiency.
3.2 Precision Repair of Connectivity Failures
Use TDR to locate faults (cable breaks, shorts, loose joints). Repair accordingly: fusion - splice fibers, weld/replace copper cables, or redo joints. Retest post-repair to ensure connectivity.
3.3 Electrical Performance Optimization
Analyze electrical parameters (impedance, resistance) and select suitable cables (e.g., impedance-matched cables for high-speed networks). Standardize construction (avoid over-bending) and regularly retest, building a performance database to detect degradation early.
3.4 Precision Length and Impedance Tuning
Use professional tools (OTDR for fibers, TDR for copper cables) to measure lengths. Match characteristic impedance to standards (e.g., 100Ω for Cat5e/Cat6 cables). Use impedance matchers if needed, ensuring efficient system operation.
4. Conclusion
Cable detection in intelligent building integrated wiring systems is fundamental to stable information transmission and system safety. Through full-process index monitoring, problem prediction, and precise repairs, we strengthen the physical link, driving the system toward greater safety, intelligence, and efficiency, supporting the high-quality development of the intelligent building industry.
