Due to the poor effect of traditional systems on constant temperature control, the paper proposes to design an embedded continuous temperature control system in a dynamic, intelligent building. In the smart building, the thesis takes the building as the research object and uses the embedded technology to design the overall structure diagram of the system. The thesis aims at the output control module of the thermostat. It uses the Peltier effect to develop the thermocouple closed-loop and drives the semiconductor refrigeration device select. In the software part, the paper establishes a cross-compilation environment, transplants embedded kernels, and sets fuzzy rules for constant temperature control. The validity of the system design is verified through experiments. It can be seen from the experimental results that the system has a better thermostat control effect.

A design approach of the temperature control of a novel microchip level PCR instrument based on SOPC technique is presented in this paper. The soft-core processor with RISC framework, NIOS II, which embedded in the FPGA (CyclonIII EP3C16F484C6) of Altera corp., is used as the key component to control the PWM controller achieving the temperature control of the micro-chamber stationary microchip level PCR instrument, to control the Avalon stream slave peripheral acquiring controller achieving the temperature signal detection by the flexible snake like copper wire temperature sensor, and to control the micro-pump and the micro-valve achieving the sample injection and sample outflow controlling. Simultaneously, the control temperature algorithm based on the Smith predictive and adaptive Fuzzy-PID is adapted in this system. The design of PCR microchip, the Smith predictive adaptive Fuzzy-PID temperature control algorithm, the hardware framework and the software design of control system are mainly introduced. And the simulation results testified the correctness of the design method and practicability.

Chicken Eggs

This research presents the design and development of a chicken egg incubator. The aim is to design and construct an “Intelligent Egg Incubator” that can hatch chicken eggs automatically. In the design, author used a temperature control system that controls the temperature of the incubator. This system consists of a temperature sensor, heating and cooling elements and a controller. If the temperature of the incubator exceeds a certain value, the cooling unit will operate to reduce the temperature while if the temperature goes below another threshold value, the heating element will start to operate to increase the temperature. Furthermore, author used a motion sensor to detect the movements of the eggs. If there is a movement inside the incubator, the owner of the incubator will get the notification about the conditions of the eggs

Abstract - Today's automatic control system provides many benefits for humans. Apart from being able to increase work time, automatic control can also reduce human errors and increase work effectiveness. One application of automatic control is controlling temperature with the aim of obtaining the desired temperature in a relatively short time and can maintain the temperature in a stable condition. The temperature control system can be applied using the Arduino and LabVIEW boards. In this temperature control system one LM35 temperature sensor is used. The temperature sensor is placed in a position that is adjusted to the inside of the plant to find the temperature transfer that occurs in the plant. Data from the sensor then goes to the Arduino board, which in this control system uses data as an acquisition. To maintain the temperature inside the factory, use a ventilation fan to lower the temperature if the temperature inside the plant exceeds the set point. To control the fan used this controls the PID which is implemented through LabVIEW. In addition to implementing the PID control, LabView is used as an interface to find out the actual temperature of the plant RPM speed of the fan used and filling in the PID parameters. In the PID approval three parameters can be obtained with Ziegler-Nichols penalties. The results of the study show that the plant response is continuous oscillation and can be overcome by using Ziegler-Nichols continuous oscillation punishment. By using LabVIEW PID and punishment parameters using the Ziegler-Nichols method, for a set point temperature of 28oC the plant response is (28 ± 0.5) oC. In other words controlling temperature using the PID control and the Ziegler-Nichols method have errors below 2% indicating that the temperature control system is feasible to use. Keyword : Temperature, PID Control, LabVIEW, Arduino board, Ziegler-Nichols.
