Grain dryers are essential equipment in post-harvest grain processing, widely used on farms, in grain depots, seed processing plants, and large agricultural cooperatives. Their operational reliability is directly tied to the safe storage and quality preservation of grain.

As one equipment manufacturer has expanded its business, its traditional after-sales service model has faced mounting challenges. With dryers deployed across major grain-producing regions nationwide, the company lacks a unified remote monitoring capability. Headquarters cannot track in real time critical parameters such as operating temperature, grain layer thickness, hot air volume, or discharge auger speed across all units. The service team has long relied on phone calls from users to report issues, and troubleshooting often requires engineers to travel to site with toolkits. This results in significant downtime losses during peak drying seasons, declining customer satisfaction, and steadily rising service costs.

To address these challenges, WideIOT offers a remote monitoring and maintenance system solution built around PLC intelligent gateways. By collecting operational data from the dryer's PLC, the system enables real-time equipment visibility, proactive anomaly alerts, and a closed-loop digital service process—shifting the maintenance paradigm from "reactive response" to "proactive prevention." Through this solution, companies can access real-time information on equipment status, geographic location, process parameters, alarm events, and work order progress for assets nationwide, enabling smart maintenance and predictive upkeep while strengthening brand competitiveness.

Key Capabilities

Multi-dimensional statistical analysis: Aggregates metrics such as runtime, throughput, energy consumption ratios, and failure frequency by customer, grain depot, region, model, and crop type. Generates reports to support management decision-making and resource optimization.

Real-time data acquisition and visualization: Uses WideIOT PLC gateways to collect parameters including incoming grain moisture, outgoing grain moisture, hot air temperature, air pressure, grain layer thickness, and discharge auger speed. Visualizes data through HMI-style dashboards and trend curves, enabling remote inspection and condition monitoring.

Intelligent alerting with tiered notifications: Allows custom alarm rules for issues such as excess moisture, temperature anomalies, insufficient air pressure, auger jamming, and burner flameout. Alerts are pushed through WeChat, SMS, and email with priority levels, and fault moment data is logged to help quickly pinpoint root causes.

Equipment mapping and resource dispatch: Displays equipment locations, online status, and alarm information on a GIS map. Supports dispatch based on nearest available technician and proactive inspection scheduling, improving service response efficiency.

Closed-loop work order management: Supports online creation, assignment, feedback, and uation for service tickets covering repairs, preventive maintenance, inspections, and machine adjustments. Real-time status tracking and full traceability ensure a complete service loop, driving continuous improvement in maintenance quality.

Remote maintenance and program updates: Enables remote upload/download of PLC programs, online debugging, and parameter tuning through the gateway, significantly reducing the need for on-site visits. This lowers service costs and ensures reliable operation during the critical drying season.
