Common Faults of Grain Silo Temperature Measurement System

In grain storage management, the grain silo temperature measurement system plays a crucial role. However, even the most precise equipment can malfunction, affecting its normal operation and data accuracy. Understanding these common faults is the first step in solving problems.

No Data Transmission Faults

No Data in the Entire Silo

In this case, all temperature data from the monitoring software interface disappears completely. Possible causes include power failure of the host, blown fuses, interruption of the main communication line, or hardware failure of the host.

No Data from a Single Sub - Machine

When data from all temperature - measuring points connected to a sub - machine is missing, while data from other sub - machines is normal, it may be due to power failure, communication line failure, or internal hardware failure of that sub - machine.

Local Data Abnormality Faults

Data Abnormality Caused by Sensor Faults

If temperature data from some measuring points is significantly out of the normal range, such as a sudden unreasonable increase in temperature at one point, while data from surrounding points is normal, it is likely due to damage or performance degradation of the temperature sensor at that point. Sensors may fail due to long - term use, compression by grain, corrosion, or external impact.

Data Abnormality Caused by Wiring Issues

Faults in temperature - measuring cables or wiring terminals can also cause local data abnormalities. For example, temperature - measuring cables may be worn, squeezed, or broken during grain loading and unloading, causing signal transmission interruption or short - circuiting, leading to distorted data.

Data Refresh Delay Faults

Data refresh delay refers to the untimely update of temperature data in the grain silo temperature measurement system. This prevents real - time reflection of actual temperature changes in the grain pile. It may be caused by insufficient processing power of the host, software failure, or limited bandwidth of the communication line.

Host and Software Faults

Host Freezing or Automatic Restart

Host freezing or automatic restart can affect the normal operation of the entire temperature measurement system. It may be caused by hardware failure, poor heat dissipation, software conflicts, or virus infections.

Abnormal Display on Software Interface

The temperature - measuring system software interface may display abnormally, such as data scrambling, incorrect graphic display, or failure of some functional modules to display properly. This may be due to software bugs, incompatibility with the operating system, or damage to software configuration files.
