Case Study | Real-World Testing During the Flood Season! After multiple rounds of heavy rainfall in July and August, with a torrential downpour of 81.2 mm/h, SPEPC reinforced its safety monitoring defenses.
Case Study | From July to August, continuous real-world operations during the flood season! In a 81.2 mm/h downpour, SPEPC once again helped the customer prevent potential risks before they occurred!
Previous episode
Since the start of the flood season, heavy rainfall has repeatedly battered many regions, underscoring that proactive risk prevention remains the pinnacle of safety management.
From the typhoons in July to the torrential rains in August, Spepc Technology has maintained round-the-clock, 7×24-hour standby.
Recently, SPEPC once again successfully helped a client identify risk points in advance before the onset of extreme heavy rainfall, nipping potential hazards in the bud.
01
Extreme torrential rain—every second counts.
On the afternoon of August 23, a railway maintenance section within its jurisdiction experienced an extremely rare and severe convective weather event, with hourly rainfall exceeding 81.2 mm—far surpassing the flood‑control alert threshold.

August 8th
In the same monitoring area, another integrated tilt-monitoring device (ID No. 26472) recorded a tilt angle of 10.2°, and both devices subsequently triggered red‑level alerts.

Devices in real-time monitoring
Precise customer handling
At the very first sign of an alert, on-duty personnel retrieved the real-time curves from the SPEPC platform and, in conjunction with on-site monitoring data and the terrain conditions during heavy rainfall, conducted a precise analysis:
This anomaly does not result from a structural collapse of the mountain retaining wall alongside the railway; rather, it is… The highway at the top of the retaining wall is hit by a swift current. , carrying debris, it physically struck the monitoring equipment mounted on the protective wall, causing the device to topple over.
The on-duty personnel immediately used the FAS system to notify all units to seal off the affected section and completed an on-site inspection.
On-site verification and corroboration
Thanks to the precise, minute-by-minute data provided by the SPEPC online platform, the monitoring room was able to pinpoint the risk location, thereby avoiding a full-line blind inspection at night.
On-site verification confirmed that the accumulated water, carrying debris, had surged with great force and struck the equipment. The damaged equipment was promptly dismantled and prohibited from being reused. , all alerts have been acknowledged and closed.
02
A review of the flood season: repeatedly victorious.
This year’s flood season saw SPEPC withstand multiple rounds of real-world testing, demonstrating its reliability under extremely adverse weather conditions.
Early July Typhoon Counterattack Battle
Faced with the heavy rainfall brought by Typhoon “Maysak,” multiple lines and monitoring stations along a coastal railway issued alerts. Equipment at locations 14441 and 14358 continuously detected deformation anomalies, triggering red alerts repeatedly. The SPEPC team maintained constant oversight and worked closely with the client to safely mitigate the typhoon’s threat.
Early morning of August 8: Precise early warning issued during a torrential rainstorm.
In a certain mountainous railway section, heavy rainfall struck unexpectedly overnight. Equipment 53729 fully recorded the entire process of the slope’s transition from stability to collapse within one hour, with the dip angle rapidly surging from 3.048° to 88.506° and continuously issuing eight consecutive alerts ranging from blue to red. On-site verification confirmed that the slope had experienced surface sliding and collapse. SPEPC helped the customer promptly detect and address the potential hazard, successfully preventing the localized slide from escalating.
03
Hardcore performance, long-lasting protection.
The string of successful early warnings is by no means accidental; rather, it is a concentrated manifestation of SPEPC’s three core strengths:
High hardware reliability
With a high‑protection‑rating design, it maintains millisecond‑level data acquisition even in harsh environments, thereby eliminating the inspection blind spots inherent in traditional manual methods under adverse weather conditions.
Highly sensitive platform
Heavy rainfall in mountainous areas does not compromise stable data transmission; multi-level threshold-based decision-making ensures tiered, step-by-step notifications, with information delivered directly to the dispatch system, thereby buying customers valuable time for response.
Data-Driven Empowerment
Provide clear, comprehensive data analytics to underpin efficient root-cause analysis, enabling customers to allocate their limited resources precisely to high‑risk areas.
Let data do the talking and reveal risks in advance.
Prevention is better than cure, and SPEPC has been taking action all along.
With “hardware” + Platform + An integrated “service” system fortifies the safety perimeter, safeguarding every mile.
