A certain chemical enterprise has hazardous chemical storage tank sites within its factory premises, featuring a large number of storage tanks with complex media types and a wide distribution range. Daily supervision heavily relies on the experience of on-site personnel and regular inspections. Given limited personnel and dispersed supervision, abnormal conditions are difficult to grasp in a timely manner, safety hazards are hard to proactively warn against, and accident risks are challenging to effectively control. Constructing a reliable, real-time, and intelligent remote monitoring and automatic alarm system has become an urgent need for the enterprise's safety management.
In response, WideIOT has deployed industrial intelligent gateways to connect with various sensors and instruments in the storage tank area (such as level gauges, temperature sensors, pressure transmitters, gas detectors, etc.). These gateways enable real-time collection of storage tank status and environmental safety parameters, with data stably uploaded to a safety monitoring management platform via 5G/4G/wired networks. This facilitates remote real-time monitoring, intelligent analysis, abnormal warnings, and emergency responses to the operational status of storage tanks, thereby enhancing safety supervision efficiency and assisting enterprises in achieving digital transformation in hazardous chemical storage tank management.
Implemented Functions1. Real-time Visual Monitoring of Storage Tank Status
Real-time collection of key parameters such as storage tank liquid level, temperature, pressure, and leaked gas concentration is conducted, with visualization displayed through various means such as data cockpits and site maps. It supports unified view management for multiple sites and storage tanks, enabling safety personnel to grasp the operational status of storage tanks anytime and anywhere.
2. Intelligent Warnings and Multi-channel Alarms
Based on preset safety thresholds and intelligent alarm rules (such as liquid level exceeding limits, abnormal temperature, sudden pressure changes, gas leaks, etc.), the system automatically identifies abnormal conditions and promptly notifies relevant personnel through various means including WeChat, SMS, email, and audible and visual alarms. This facilitates a shift from "post-event handling" to "pre-event warnings."
3. Work Order Closure and Emergency Tracking
Abnormal events automatically generate maintenance work orders or inspection tasks, supporting task assignment, process tracking, result feedback, and closed-loop management of work orders. The system records logs throughout the entire process, facilitating responsibility tracing and safety management optimization, and enhancing emergency response efficiency.
4. Equipment Archives and Compliance Management
Electronic archives for storage tanks and sensor equipment are established, recording information such as equipment models, installation locations, commissioning times, calibration cycles, and maintenance records. It supports quick querying and editing of information, assisting enterprises in completing safety compliance inspections and equipment lifecycle management.
5. Historical Data Retrieval and Analysis Reports
The system stores monitoring data over the long term, supporting multi-dimensional queries and trend analysis by time, site, storage tank, etc. It automatically generates safety operation reports and event statistical reports, providing data support for safety management decision-making and risk analysis.
