The primary objective of this final year project was to design and construct a control system for a climate chamber which is fully and automatically operated with the use of a Siemens Programmable Logic Controller (PLC). The project was given to the UrbanFarmLab of Metropolia University of Applied Sciences (UAS) with the aim of improving the accuracy and repeatability factors of the environmental conditions inside the chamber, which for the purposes of the UAS is especially important.
The thesis presents the design and programming of a PLC based system that includes sensors and actuators to control the following system variables: temperature, humidity, level of CO2 and lighting. The implemented solutions included interfacing devices such as a Modbus communication protocol, time schedule-oriented algorithms and error management subsystems for the active protection of the integrated system. The Siemens TIA Portal was the included software for the configuration and programming of the PLC.
The self-contained climate chamber control system has been completed and it supports two modes of operation: manual and automatic. The designed system is able to keep within the preset range of environmental parameters with little input from the user, and it allows monitoring the process through a user-friendly interface. Suggested improvements for the next versions of the system development are adding more sensors, adding an NTP time server for time synchronization and improving the data logging features of the system.
This project offers a complete approach to climate chamber automaton and serves as a preview into greater possibilities in the rollout of vertical farming and preservation systems respectively.
