Facing Typhoon “Maysak” — Guilin SPEPC’s intelligent monitoring equipment provides continuous early warnings, working in coordination with coastal railway maintenance units to safeguard the slope safety防线.

I. With the combined onslaught of a typhoon and torrential rains, the risk of slope deformation along the route has surged dramatically.

Under the combined influence of the typhoon’s outer circulation and the monsoon, coastal areas have experienced prolonged heavy rainfall for several consecutive days. The persistent infiltration of rainwater into slope soils has reduced soil–rock friction, while the strong winds associated with the typhoon have further destabilized the slope surfaces, leading to progressive soil failure along numerous steep slopes within the pipeline corridor. Body slip.

Key flood‑control sections of the relevant lines: As a key monitoring site directly exposed to typhoons along the coast, multiple instruments have exhibited significant deformation; at some stations, the tilt angle has reached as high as 36.867°, triggering red‑level alarms and highlighting an acute risk of slope‑soil displacement.

Upon receiving the alert, the inspection team promptly proceeded to the location of the warning device and captured on-site photographs.

Equipment on the site’s slope has tilted severely.

All alarm notifications are uploaded to the monitoring platform in real time, and all are closed through online confirmation by the track maintenance unit.

II. SPEPC provides 24/7 end-to-end monitoring and, during the typhoon, simultaneously delivers multi-dimensional risk information.

From the moment the typhoon warning was issued, SPEPC activated its special duty plan for extreme weather, assigning dedicated operations and maintenance personnel to station around the clock at the monitoring center. From the initial alert pop-up to the complete resolution of all potential hazards, they tracked equipment operation and data changes throughout the entire process, providing end-to-end support to help customers carry out typhoon‑related flood‑control efforts:

• Real-time tracking of typhoon-related data trends
  • During typhoon and heavy‑rain events, data acquisition is intensified, with continuous monitoring of the tilt‑angle time series for each alarm‑triggering device. The rate of numerical increase, abrupt change points, and the sequence of alert escalations are meticulously recorded, and the full‑duration raw monitoring data throughout the typhoon’s passage is securely preserved. This process establishes a comprehensive ledger of slope deformation, providing clients with original evidence for post‑event analysis of typhoon‑induced hazards.
• Tiered Synchronized Risk Alert Information
  • For each instance of data anomaly, alarm level escalation, or abrupt change in measured values, the system promptly collates the corresponding location, real-time tilt angle, trend‑line variations, and risk rating, and immediately forwards this information to the railway‑maintenance management team and the on‑site work‑area supervisors. Critical high‑tilt and sudden‑change risk points are prominently flagged, providing precise data support for emergency on‑site inspections during typhoon conditions and significantly reducing the time required for field assessment.
• Online technical support is available around the clock.
  • While inspection personnel braved the rain to go on-site to verify slope hazards, Spepc Technology’s technical staff maintained real-time communication, interpreting monitoring curves and equipment operating statuses at all times, helping to distinguish between minor fluctuations caused by typhoon winds and rainfall interference and the slope’s actual soil deformation, thereby assisting the work area in quickly assessing the severity of the hazards and precisely allocating emergency response personnel.

Relying on the SPEPC duty mechanism, we have achieved efficient coordination—“on-site equipment alarms trigger—intelligent analysis on the SPEPC platform—data synchronized online to customers—on-site verification and confirmation”—thus closing the early-warning response loop even in adverse weather conditions.

III. Smart Monitoring Devices Stand Up to Typhoons and Heavy Rain, Addressing Gaps in Extreme-Weather Safety Measures

The coastal railway runs along the Gulf of Tonkin, where typhoons and torrential rains are frequent each summer, and the沿线 slopes are densely packed with steep embankments in areas underlain by soft, unstable geology.

Traditional manual inspections are constrained by strong winds, heavy rainfall, and poor nighttime visibility, making continuous monitoring impossible. Early-stage, subtle slope movements are difficult to detect promptly, and by the time cracks or collapses become visible to the naked eye, the associated risks have already fully materialized.

The Guilin SPEPC integrated tilt monitoring instrument is equipped with a high-precision, waterproof and lightning-proof angle sensor.

The system boasts a high level of overall protection, enabling stable data collection even under harsh conditions such as typhoons, heavy rainfall, and strong winds, and automatically monitoring millimeter‑scale angular changes in slopes 24/7. It comes preconfigured with multiple gradient‑based alarm thresholds; when the slope angle exceeds the safe range, it issues tiered alerts in real time, promptly detecting early signs of slope creep triggered by typhoons. This effectively addresses the monitoring gaps inherent in traditional inspection methods during extreme weather, making it an all‑weather “electronic sentinel” for railway slopes during the typhoon season.

This case of simultaneous early warning and response at multiple locations during the typhoon’s passage fully demonstrates the practical value of the integrated oblique monitoring system under extreme weather conditions such as typhoons and heavy rainfall, and also highlights Guilin SPEPC’s integrated service capabilities—comprising hardware deployment, specialized backend standby for special circumstances, and real-time information synchronization.

IV. Continuously improve the collaborative support mechanism and strengthen flood‑control defenses.

Going forward, SPEPC will, in light of the geological challenges and frequent coastal typhoons in South China, upgrade its full-cycle operation and maintenance support plan to continuously safeguard areas prone to geological disasters.

• Establish a dedicated on‑call mechanism for typhoons, heavy rainfall, and the flood season; during each year’s flood season and typhoon season, increase the frequency of backend monitoring, and promptly notify customers of any data anomalies.
• We provide regular on-site services, including equipment calibration, lightning‑protection inspections, and waterproofing maintenance, to ensure the stability and reliability of sensor data under extreme weather conditions.
• Optimize the data‑analysis model for typhoon periods to distinguish wind‑induced disturbances and rainfall interference from genuine slope deformation, refine the tiered alert‑delivery process, and enhance the accuracy of risk identification.
• Deeply collaborate with the engineering and maintenance units to refine the standardized safety management process encompassing “typhoon forecasting—intelligent monitoring and early warning—vendor information synchronization—on-site emergency response and remediation—closed-loop alarm resolution.”

Technology rises to the challenge of the flood season, working in concert to safeguard infrastructure. Spepc Technology will continue to ensure slope flood protection and subgrade safety during typhoon season with its stable, reliable smart monitoring hardware and round-the-clock professional backend operations and maintenance services.
