On May 29, 2026, a flash fire occurred during the major overhaul of the No. 1 ethylene plant at Sinopec Yangzi Petrochemical Company’s Olefins Division, killing four contractor personnel. On June 24, 2026, a flash explosion occurred during the reassembly of trays in the sulfolane solvent recovery tower of the No. 2 reformer unit at the company’s Aromatics Division, resulting in two deaths and three injuries. Within a single month, the same enterprise experienced two similar accidents, exposing deep‑rooted issues: inadequate risk identification, lax enforcement of safety measures, and critical management loopholes in special operations.

Looking across the industry, non‑routine operations such as maintenance, repair, and modification in high‑risk enterprises like petroleum and chemical plants are plagued by common problems: blind spots in manual supervision, delays in gas monitoring, lack of process traceability, and supervisory monitoring that exists only on paper. To address these practical challenges, Bangandi has independently developed the “Intelligent Monitoring Terminal for Special Operations” (the fifth‑generation “Safety Guardian”). It is an industrial‑grade intelligent explosion‑proof device purpose‑built for flammable, explosive, toxic, and hazardous industries such as petroleum, chemicals, and coal mining. It can collect and alert on real‑time gas concentration data at operation sites, and through visualization combined with intelligent AI, ensures the safety of production operations and enables full‑process real‑time monitoring.

1. Core Intelligent AI Technologies Building a Strong Safety Defense Line

The product deeply integrates cutting‑edge technologies including edge computing architecture, deep‑learning‑based behavior recognition, dynamic ROI tracking, intelligent gas cross‑validation, spatio‑temporal situational awareness, and a dynamic graded response handling mechanism. On the hardware side, it is equipped with a 360° panoramic camera, an industrial‑grade large touchscreen, ad‑hoc network communication, Beidou/GPS positioning, real‑time voice intercom, and a four‑gas simultaneous detection module. On the AI side, the panoramic camera runs at least four parallel algorithms simultaneously, enabling face recognition, unsafe behavior detection (hard hat, smoking, seatbelt, workwear, etc.), abnormal personnel posture detection, and job qualification verification. During operations, the terminal collects real‑time gas concentration and environmental status data, working in parallel with AI visual analysis to truly achieve “one device managing the entire site.”

2. Full‑Process Closed‑Loop Management Leaving No Safety Blind Spots

The product is deeply integrated with the electronic work permit management system, fully digitizing and standardizing the traditionally offline approval process. It enables a full‑process closed‑loop management chain from “identity verification – permit approval – on‑site condition confirmation – execution – acceptance and archiving.” Before work begins, if any prerequisite condition is not met, the operation cannot start, eliminating “work without a permit” and “missing safety measures” at the source. During operations, four‑gas monitoring and AI visual analysis run in parallel. If gas exceeds limits or violations occur, the system triggers a three‑level warning according to risk level – on‑site audible/visual alarm, platform pop‑up, and escalated alert to the responsible person – and automatically generates a handling work order. From detection, assignment, handling, to verification and archiving, the entire chain is closed‑loop and traceable, ensuring that anomalies are trackable and accountability is enforceable.

3. Multi‑Case Data Evidence Proving Product Effectiveness

To date, the product has been widely deployed among numerous clients in the petroleum, chemical, coal mining and other industries, receiving consistently positive feedback. For example, after Hubei Jianghan New Materials Co., Ltd. deployed Bangandi’s intelligent monitoring terminal for special operations, the work permit approval cycle was reduced from 6 hours to 30 minutes, high‑risk operation violations dropped by 80%, and annual labor cost savings exceeded RMB 2.8 million. After deployment at a subsidiary of China Energy Investment Group, operational compliance improved significantly, emergency response speed accelerated markedly, and overall emergency management efficiency and safety management levels were substantially enhanced. In addition, Bangandi’s products have been selected for three consecutive years into the “Catalog of Applicable Technologies for Smart Chemical Industrial Parks” and have been included in MIIT’s “2025 Typical Application Cases of Advanced Computing Empowering New Quality Productive Forces.” With over 300 patents and software copyrights, Bangandi is a national key “Little Giant” enterprise, and its technical strength and service capabilities have received authoritative industry recognition.
