Project Background

A water utility management company is responsible for the operation and management of the cooling water circulation system in a shopping mall, which has already achieved PLC-based automated operation. Over time, the circulation water equipment has experienced an increasing frequency of abnormal faults, leaving operation and maintenance personnel exhausted from constant travel and facing an increasingly heavy workload. In consideration of duty costs and operational safety, the company requires data acquisition and remote monitoring of the water circulation equipment to achieve precise and efficient operation and maintenance, thereby reducing costs and improving work efficiency.

Solution Overview

The site includes water supply equipment, cooling towers, submersible pumps, direct drinking water equipment, and other facilities, all of which have been connected to PLC electrical control cabinets. The PLCs are connected to industrial intelligent gateways via RS485 interfaces, and the gateways convert the data into 4G communication for transmission, enabling the IoT cloud platform to perform real-time monitoring, fault alarms, remote control, remote maintenance, and other operations on the entire water circulation equipment.

Implemented Functions

Intuitively view the operating status and process parameters of the circulating water treatment equipment, with configuration and synchronous display on the configuration interface, supporting multi-screen switching and zooming in/out for quick problem localization.

Based on intelligent early warning rules, monitor abnormal data to provide early warnings of equipment faults and automatically send warning messages to relevant personnel, shortening fault response time, with support for notification methods such as WeChat, SMS, and email.

Remote control: Support remote start/stop and speed regulation control of equipment such as water pumps and valves, enabling flexible scheduling and emergency response.

Remote maintenance: Enable operations such as remote programming and debugging and remote program upload/download for PLCs at remote locations, improving work efficiency.

Data analysis: Custom-generate performance reports, alarm reports, sewage discharge reports, and other reports to provide decision support for enterprise management.

Maintenance management: Establish equipment maintenance archives, record repair history, and remind of regular maintenance to extend equipment service life.
