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.

The system of control and maintenance of temperature in the tank used for fatigue tests of the elements is presented. The designed system enables reaching and maintaining a constant temperature in the range from 17 to 45ºC with a slope of ±0.5ºC. The temperature control system was implemented using the Peltier cells and the Arduino Uno control system.

If the intelligent building?s indoor environment?s constant temperature is accurately controlled, the comfort of the building can be improved. When we perform constant temperature control, there will be large fluctuations in the supply air temperature, which results in the traditional methods that cannot control the temperature within a reasonable range. Therefore, the paper proposes an optimal control method for the indoor environment constant temperature of intelligent buildings. In the IoT environment, we integrate the multi-agent technology to design the temperature fuzzy control structure, determine the input and output variables of the intelligent building temperature control system and its fuzzy set, use the dynamic analysis method to modify the fuzzy rules, and integrate it with bilinear The control algorithm builds a dynamic temperature control model for intelligent buildings to maintain the indoor temperature at the set value when the supply air temperature fluctuates significantly. This method makes up for the shortcomings that the current system cannot adapt to the intelligent building environment changes. The simulation results show that compared with the traditional algorithm, the improved algorithm can significantly improve the robustness of the intelligent building constant temperature control, and the temperature control stability is vital.

Integrated temperature sensor of current mode is made based on the principle of relation between forward current of PN junction and temperature. It is of very good linearity, inter-exchange and accurate measurement, which has been brought to close attention of the industry recently. The paper focuses on the introduction of the principle of PTAT integrated temperature sensor of current mode and detailed analysis of the product of the type .In addition, the scheme, used for constant temperature control inside the furnace, is designed with the temperature control system consist of current mode integrated temperature sensor AD590.
