Wuzhou Slope-Cutting Housing Construction Visual Intelligent Deformation Monitoring Project
At a site in the Wuzhou region of Guangxi, a visual‑intelligence deformation monitoring system was deployed on‑site. The equipment was mounted on a rooftop observation platform to perform real-time displacement monitoring of 16 passive infrared targets installed on the slope behind the building. The platform provides real-time displays of horizontal and vertical displacement curves as well as the device’s temperature‑control curve, supports displacement alarms and target‑loss alerts, and enables non‑contact, sub‑millimeter‑level landslide monitoring.

Automated Monitoring Project for Debris Flow Hazard Sites in Nyingchi, Tibet
In 2022, SPEPC, as the leading entity, participated in a field trial project organized by the Geological Disaster Technical Guidance Center of the Ministry of Natural Resources. It was responsible for constructing automated monitoring stations at three debris-flow hazard sites in Chawalong Township, Nyingchi City, Tibet, installing equipment such as rain gauges, mud-water level monitors, and audio‑visual alarms. The project successfully withstood the glacial plateau environment, validating the reliability and stability of the monitoring devices in high‑altitude, cold regions.

Guangxi Land Subsidence Monitoring Network Construction Project
In 2024, Spepc Technology participated in Guangxi’s first large-scale ground subsidence (karst collapse) monitoring network project, providing 170 sets of water–gas pressure sensors for karst conduit and fracture systems, 58 water-level monitors, 52 deep-displacement devices, 7 automatic rain gauges, and one set of monitoring data platform software across 23 monitoring zones in six cities including Guilin, Liuzhou, and Yulin. All equipment was integrated into Guangxi’s ground subsidence monitoring and early-warning platform, enabling real-time collection of water–gas pressure, groundwater level, deep displacement, and rainfall data, along with tiered early warnings. The project passed expert acceptance at the end of 2024, effectively addressing the shortcomings in monitoring and early warning in areas of severe karst collapse in Guangxi and providing technical safeguards for the safety of railways, bridges, municipal infrastructure, and residential areas.

Liuzhou Sanjiang Debris Flow Emergency Monitoring Project
On September 11, 2020, Gaonong Village, Yanjiao Town, Sanjiang County, Liuzhou City, was hit by continuous heavy rainfall. The emergency monitoring equipment constructed by Spepc Technology issued continuous audio‑visual alarms before the debris flow occurred, enabling villagers to evacuate promptly and successfully avoid the disaster, with no casualties. This case was featured in special reports on CCTV News Channel 13 and CCTV-4, the Chinese International Channel.

Guizhou Geological Disaster and Territorial Security Monitoring Project
Guizhou is located in the eastern part of the Yunnan–Guizhou Plateau, where the geological environment is fragile and geological hazards are frequent. The project has deployed integrated inclinometers, landslide monitors, rain gauges, crack meters, radar water level sensors, and other instruments at numerous potential hazard sites across the province, enabling automated monitoring and early warning and providing technical support for disaster prevention and mitigation.

Guangxi Large-Scale Monitoring Station Construction Project for 2022–2024
From 2022 to 2024, SPEPC consecutively won bids for Guangxi’s geological hazard monitoring and early warning projects, cumulatively establishing hundreds of automated monitoring stations and deploying equipment such as tilt‑angle accelerometers, rain gauges, and soil moisture sensors. These devices transmit data via 4G or LoRa to the provincial early warning platform, enabling round‑the‑clock monitoring and intelligent early warning at potential hazard sites.
