| Abstract: | According to the system of temperature acquisition in the environment of high temperature in the industrial production, the system is presented in this paper. This system with type-K thermocouple and MAX6675 which is an AD conversion chip of type-K thermocouple in the charge of microprocessor to collect multiplex temperatures, and with the application of RS485 wireless module to transmit temperature data to PC. This paper makes a detailed discussion about technology of data acquisition and wireless transmission. The ex- periment results show that the system can gather temperature data within the allowed error range of temperature data accurately, and transmit data to PC in a real time, steady, exact and wireless way. And it proves that the system has good performance. |
