| Abstract: | The paper deals with the design of a set of multi - channel, real time and high precision temperature control system for mission nodes. TQ2440 intelligent terminals of Internet of things like UHF reader, information collection and transas the master mask, the development is based on Linux operating system. Using its own A/D channel for two -way temperature collecting, and the data can be transferred to the PC by a wireless network card, achieving communication between with host computer and slave computer. Using Qt/Embedded graphical control interface and the PID control algorithm to adjust, feedback and precisely control temperature, the system can provide guarantee to realize intelligent control for related equipments. |
