Construction of Grain Silo Temperature Measurement System

Achieving precise and real - time monitoring of grain silo temperature. The following will delve into the construction of the grain silo temperature measurement system to help you fully understand its operating principles and core components.

Hardware Composition

Temperature Sensors

Thermistors measure temperature based on the characteristic that metal resistance changes with temperature. They are highly accurate and stable, making them suitable for medium - and low - temperature environments. Thermocouples work based on the Seebeck effect. They have a simple structure, fast response speed, and wide measurement range, making them suitable for high - temperature measurement.

Temperature - Measuring Cables

To ensure accurate and stable signal transmission, temperature - measuring cables should be laid neatly and standardized during installation. Avoid crossover and tangling. Properly secure the cables and fit them with dedicated protective conduits. This enhances their resistance to pressure, pulling, and corrosion, extending their service life.

Host and Sub - Machines

The host receives temperature data from sub - machines, displays, stores, and analyzes it in real - time. It visually presents the temperature distribution in different areas of the grain silo through a software interface. This allows managers to check it at any time. Sub - machines act as intermediaries between the host and sensors. They receive temperature signals from sensors, convert them into digital signals, and pass them on to the host.

Software Composition

Data Acquisition and Transmission Software

Running on sub - machines, this software collects temperature data from sensors. It converts the data into digital signals and transmits them to the host via wired or wireless communication. It has efficient data acquisition capabilities and stable communication performance to ensure timely temperature data transmission.

Data Processing and Analysis Software

By setting temperature thresholds and early - warning rules, this software monitors grain silo temperature changes in real - time. It triggers alarms when temperatures exceed normal ranges, alerting managers to take action. It also features data visualization, displaying grain silo temperature distribution and trends in the form of charts and curves.

Auxiliary Facilities

Protective Devices

Sensors are usually equipped with protective covers to prevent damage from grain compression, collision, and rodent attacks. Hosts and sub - machines are installed in protective cases. These cases have good sealing properties to resist humid air and dust intrusion. They also prevent accidental damage to equipment from human operations.

Fixing Devices

Sensors are fixed to the silo walls, roof, etc., using pre - embedded brackets or expansion bolts. Temperature - measuring cables are orderly laid along the silo structure using cable clips and hooks. They are closely attached to the silo walls or grain - pile surface to prevent cable damage from suspension and swinging.
