Industry News | Smart Grain Storage | September 2026
Smart grain storage is changing how grain reserves are monitored, managed, and protected. Instead of relying solely on periodic manual inspections and individual temperature readings, modern grain warehouses increasingly use connected sensors, centralized data acquisition, and automated warning systems to monitor storage conditions.
The Wusheng County Grain Storage and Logistics Center in Sichuan Province, China, provides a practical example of this transition. With 28 grain warehouses and a designed storage capacity of 100,000 metric tons, the facility demonstrates how temperature, humidity, grain moisture, and equipment operating data can be integrated into a centralized smart warehouse management system.
This article examines the project's monitoring architecture, the role of multi-point temperature cables, and the implications for grain storage monitoring equipment and system integration.

1. Inside the Wusheng Smart Grain Storage Project
According to a September 1, 2026 report by Sichuan News (Chuan Guan News), the Wusheng County Grain Storage and Logistics Center in Guang'an, Sichuan, has introduced digital monitoring across its grain storage facilities.
Hundreds of intelligent sensors collect information from different positions and depths within grain piles. The resulting data is transmitted to a centralized management platform, allowing operators to check warehouse conditions from a control room rather than manually measuring every monitoring point.

The project illustrates an important change in grain storage management: operators are moving from checking individual measurement points to managing storage conditions across an entire warehouse complex.
A centralized platform makes it possible to identify which warehouse requires attention, locate abnormal monitoring points, and review the information needed for further investigation.
2. From Manual Inspection to Continuous Temperature Monitoring
Traditional grain inspection requires workers to enter warehouses and measure temperatures at selected locations.
This process becomes increasingly time-consuming as warehouse size and the number of monitoring points increase. Deep grain layers can also be difficult to inspect without disturbing the stored grain.
At the Wusheng facility, temperature measurement cables are installed at designated positions and depths within grain piles. Their sensors continuously collect temperature information and transmit readings to the monitoring system.
When abnormal temperatures are detected, the system can issue warnings and help workers identify the affected area.

How multi-point temperature monitoring works
A typical monitoring system follows this data path:

By installing multiple cables throughout a warehouse, operators can build a monitoring network that covers different grain layers and storage areas.
This makes it possible to examine temperature distribution rather than relying on a single reading to represent the condition of an entire grain pile.
3. Why Multi-Parameter Monitoring Matters
Grain temperature is an important indicator of storage conditions, but temperature alone cannot explain every change inside a grain pile.
Moisture, environmental humidity, insect activity, and ventilation conditions may also affect storage safety.
Multi-parameter monitoring brings these measurements together so that operators can interpret abnormal readings with more context.
The Wusheng facility's reported system combines temperature, humidity, grain moisture, equipment operating information, and pest warnings within its management platform.
Typical monitoring parameters and applications
|
Monitoring parameter |
What it measures |
Practical application |
|---|---|---|
|
Grain temperature |
Temperature at different depths and positions |
Identify localized heating and monitor temperature trends |
|
Relative humidity |
Humidity in the warehouse or selected monitoring locations |
Evaluate environmental conditions and condensation risk |
|
Grain moisture |
Moisture content of stored grain |
Support moisture management and storage decisions |
|
Insect monitoring |
Pest activity or detection information |
Identify potential insect infestations |
|
Equipment status |
Operating conditions of fans, cooling units, and other equipment |
Detect faults and verify equipment operation |
|
Gas concentration |
Selected gases where suitable monitoring equipment is installed |
Support controlled-atmosphere storage and relevant safety procedures |
These parameters do not necessarily require the same sensor or cable. For example, grain moisture content and relative humidity are different measurements and must not be treated as interchangeable.
The choice of sensors depends on the grain type, warehouse design, storage conditions, and monitoring objectives.
4. Multi-Point Temperature Cables: The Foundation of Internal Grain Monitoring
One of the most important components of a grain monitoring system is the temperature cable.
A multi-point temperature cable contains several sensors positioned along its length. When the cable is installed vertically inside a grain pile, these sensors can measure temperatures at different depths.
For larger warehouses, multiple cables can be distributed across the grain pile to create a spatial monitoring network.

Example: Temperature measurements at different depths
The following table uses hypothetical readings to illustrate how a multi-point monitoring system can help identify a localized temperature difference.
|
Monitoring depth |
Cable A |
Cable B |
Cable C |
|---|---|---|---|
|
2 m |
23.6°C |

|

|
6 m |
24.8°C |
24.3°C |
24.5°C |
|
8 m |
31.2°C |
24.6°C |
24.7°C |
Illustrative data only; these are not measurements from the Wusheng facility.
In this example, Cable A reports 31.2°C at a depth of 8 meters, while nearby measurement points report considerably lower temperatures.
The difference would warrant further investigation, including checking the sensor, reviewing previous readings, and examining conditions around the affected area.
An isolated high reading does not, by itself, establish that grain is deteriorating. Sensor faults and other causes must also be considered.
Important cable selection considerations
For grain warehouse operators and system integrators, cable selection should consider mechanical strength, installation length, sensor spacing, measurement accuracy, environmental resistance, and maintenance requirements.
Replaceable sensor designs may also reduce maintenance complexity where a compatible cable construction and installation method permit replacement without removing the entire assembly.

5. Centralized Monitoring Across Multiple Warehouses
Individual data acquisition devices can collect measurements from a particular group of sensors. However, managing 28 warehouses requires a broader information structure.
A centralized monitoring platform can organize measurements by warehouse, cable, sensor, and monitoring depth.
For example:

A system organized this way can support warehouse-level dashboards, historical records, alarm management, and equipment maintenance.
It also creates opportunities to integrate sensor readings with ventilation and cooling equipment.
The Wusheng project demonstrates the value of this centralized approach: operators can select a warehouse on the control-room display and examine temperature, humidity, and pest-warning information for different locations.

6. From Temperature Monitoring to Early Warning
Collecting temperature data is only the beginning.
A monitoring system becomes more useful when operators can identify abnormal changes and review how conditions have developed over time.
Consider the following two hypothetical temperature sequences:
Stable readings
24.4°C
Latest reading
24.2 → 24.3 → 24.4°C
Rising temperature
31.2°C
Latest reading
24.2 → 25.8 → 31.2°C
Hypothetical examples for explaining trend analysis. No specific monitoring interval is implied.
The second sequence shows a substantial temperature increase. A properly configured system could flag the change for investigation.
Different alarm strategies may include:
|
Alarm method |
Detection principle |
|---|---|
|
Absolute temperature threshold |
A reading exceeds a configured limit |
|
Temperature rise |
Temperature increases beyond a configured amount over a defined period |
|
Temperature difference |
A monitoring point differs significantly from relevant nearby points |
|
Sensor communication failure |
Expected sensor data is missing or invalid |
|
Equipment fault |
A connected device reports an abnormal operating condition |
Alarm thresholds should be configured according to grain type, storage conditions, applicable requirements, and the operator's management procedures.
The Wusheng system reportedly provides warnings when abnormal local temperatures are detected, allowing personnel to locate the relevant area more quickly.
7. Connecting Monitoring Data With Ventilation and Cooling Equipment
A modern smart grain warehouse can use monitoring data to support storage-condition management.
The Wusheng facility has deployed air-conditioning temperature control, intelligent ventilation, grain-condition monitoring, video surveillance, and recirculation fumigation systems.
The original report also describes the use of grain cooling equipment and states that, under the reported operating conditions, the grain pile can be maintained below 20°C when additional cooling is required.

Illustrative image: Cooling and ventilation equipment used in grain storage facilities.
A typical monitoring and response workflow
1
Continuous monitoring
Sensors collect temperature and other relevant measurements from the grain pile.
2
Abnormal condition detected
The platform identifies a measurement or trend that meets an alarm condition.
3
Location and verification
Personnel examine the affected warehouse, sensor position, historical records, and equipment condition.
4
Corrective action
Authorized personnel determine whether ventilation, cooling, further sampling, or another intervention is appropriate.
5
Follow-up monitoring
The system continues collecting data to help evaluate the response.
Automation should operate within appropriate safety controls and operating procedures. For example, ventilation decisions should account for outdoor air conditions and the potential for moisture movement or condensation.
The presence of a monitoring system does not mean every abnormal temperature should automatically trigger ventilation.
8. Smart Monitoring Does Not Eliminate On-Site Inspections
Digital monitoring provides continuous information, but physical inspections remain necessary.
According to the Sichuan News report, the Wusheng facility maintains 24-hour staffing, continuous control-room supervision, and hourly patrols around its warehouses.
When the system detects abnormal grain conditions or equipment failures, duty personnel respond on site.
The operating model therefore combines digital monitoring with human verification and intervention.
Sensors provide measurements, the software organizes and analyzes data, and trained personnel investigate abnormalities and implement appropriate measures.
This combination is particularly important when dealing with sensor failures, unexpected equipment behavior, and safety-sensitive grain storage operations.
9. What the Wusheng Project Means for the Grain Monitoring Industry
The Wusheng project provides a useful example of how grain monitoring requirements are expanding beyond individual instruments.
For equipment manufacturers and system integrators, this development has implications for sensor design, acquisition capacity, communication compatibility, and software integration.

These are general integration options, not a statement that the Wusheng project uses any particular communication protocol.
Moving beyond a standalone temperature instrument
For a small installation, an individual temperature reader may provide the required information.
For a multi-warehouse facility, additional capabilities become relevant: centralized acquisition, consistent sensor identification, data transmission, historical records, alarm processing, and integration with other warehouse equipment.
This creates a broader role for temperature cables and acquisition devices as components of an interconnected monitoring system.

10. A Broader Development in China's Grain Storage Sector
The Wusheng example also sits within a wider effort to improve grain storage facilities through digital monitoring and automation.
On July 2, 2026, China's National Food and Strategic Reserves Administration published guidance on developing safer, smarter, greener, and more accountable grain storage facilities.
The guidance addresses improvements in real-time monitoring, sensor placement, digital workflows, and automation of ventilation, temperature control, and controlled-atmosphere storage operations. It also encourages the use of technologies including the Internet of Things, data analytics, and intelligent early warning.
These measures establish a policy direction for smart grain storage development. They do not mean that every existing warehouse is required to replace all its monitoring equipment immediately.
For facility operators, the appropriate modernization approach depends on existing infrastructure, storage capacity, operational needs, and project budgets.
Conclusion: From Measuring Grain Temperature to Managing Storage Conditions
The Wusheng County Grain Storage and Logistics Center illustrates how connected sensors and centralized monitoring can change day-to-day grain storage operations.
Temperature measurement cables collect information from inside grain piles. Data acquisition equipment brings readings together. Communication systems deliver information to management platforms. Monitoring software makes it possible to review conditions, examine trends, and identify abnormal areas.
At the same time, ventilation and cooling equipment can be managed with reference to the collected data, while warehouse personnel remain responsible for inspection and corrective action.
For the grain monitoring industry, the practical development is clear: temperature measurement is becoming one part of a wider system for understanding and managing grain storage conditions.
The goal is not simply to display more sensor readings. It is to make grain conditions easier to observe, abnormal changes easier to investigate, and storage decisions better supported by reliable data.
