Troubleshooting for Temperature Measurement System

In grain storage management, the temperature measurement system is crucial for ensuring grain quality and storage safety. This article details common faults and their solutions to help managers quickly respond and ensure system stability.

No Data Transmission Troubleshooting

No Data in the Entire Silo

When all temperature data on the monitoring software interface disappears, first check if the host power supply is normal. Check if the power socket is loose or the power cord is damaged. Replace the power cord or restart the power equipment if necessary. If the power is fine, check if the main communication line is interrupted.

Check for breaks, aging, or short - circuits in the communication lines from the host to the sub - machines. Use a multimeter to test the continuity of the lines. Repair or replace the lines if there are any issues.

No Data from a Single Sub - Machine

Check if the sub - machine's power module is damaged and unable to provide stable power support for the sub - machine and sensors. It could also be a communication line fault. Check for breaks, aging, or short - circuits in the communication lines from the sub - machine to the host. Re - tighten the wiring terminals and repair or replace any damaged lines.

Local Data Abnormality Troubleshooting

Data Abnormality Caused by Sensor Faults

Remove the sensor from the grain pile and test it in a standard temperature environment, such as an ice - water mixture (0℃) or a constant - temperature water bath (30℃). Check if the sensor's output value is accurate. If the sensor is faulty, replace it with a new one.

Data Abnormality Caused by Wiring Issues

Faults in temperature - measuring cables or wiring terminals can also cause local data abnormalities. Check if the temperature - measuring cables have been worn, squeezed, or broken during grain loading and unloading, causing signal transmission interruption or short - circuiting. Re - tighten the wiring terminals, repair or replace any damaged cables, and ensure stable signal transmission.

Data Refresh Delay Troubleshooting

Host Fault

This may be caused by insufficient host processing power, software faults, or limited communication line bandwidth. First, try restarting the temperature measurement system software to see if data refresh returns to normal.

If it's a software fault, contact the supplier for technical support or update the software version. If the host has been in use for many years and hardware aging has led to insufficient processing power, consider upgrading the host's CPU, memory, or hard drive to improve its running speed and data processing ability.
