Working Principle of Temperature Measurement System

The working principle of the temperature measurement system, as the core of this technology, plays an indispensable role. This article will delve into the working principle of the temperature measurement system, revealing how it works together to provide comprehensive temperature monitoring for grain silos.

Signal Acquisition

Layout of Temperature Sensors

The working principle of the temperature measurement system begins with the layout of temperature sensors. These sensors are evenly distributed throughout the grain pile, with one every 2 meters, capable of sensitively detecting subtle changes in grain temperature. They act like the "sensory nerves" of the grain silo, penetrating deep into the grain pile to monitor temperature fluctuations in real - time.

Initial Data Acquisition

When grain temperature changes due to respiration, microbial activity, or other factors during storage, temperature sensors immediately detect and record these changes. These sensors convert temperature signals into electrical signals, preparing for subsequent data transmission and processing.

Data Transmission and Processing

Signal Conversion and Transmission

The analog signals obtained by temperature sensors are transmitted through temperature - measuring cables to the sub - machine. In the sub - machine, these analog signals are converted into digital signals for further data processing. This conversion process is a key step in the working principle of the temperature measurement system, ensuring the accuracy and reliability of the data.

Data Analysis and Processing

The converted digital signals are transmitted to the host in the control room. The host, as the core of the temperature measurement system, is responsible for in - depth analysis of these data. By setting temperature thresholds and early - warning rules, the host can determine in real - time whether the grain pile temperature is normal. Once abnormal temperatures are detected, the system immediately triggers an alarm to alert managers to take action.

Control and Feedback

Early Warning and Ventilation Linkage

The working principle of the temperature measurement system is not only reflected in data acquisition and analysis but also in its closed - loop management capability. When the host detects abnormal temperatures, in addition to triggering an alarm, it can also link with the ventilation equipment of the grain silo. By automatically starting the ventilation system to lower the grain pile temperature, the temperature measurement system achieves precise control of the grain silo temperature.

Data Storage and Query

The host also stores temperature data in the cloud or a local database. Managers can query historical temperature records at any time, analyze temperature trends, and provide data support for long - term temperature management of the grain silo. This function makes the temperature measurement system not only capable of real - time monitoring but also able to provide a basis for future decision - making.
