Abstract:Abstract: Temperature control has been a very important control, and because of the large hysteresis control object characteristics, the precise temperature control and handling of which is difficult.The research object of this design is the temperature examination. Through the reasonable use of data collecting technology and wireless communication, the author proposes a multi-channel temperature survey system with the monolithic integrated circuit and the wireless transmission module being its core, and makes a comparatively comprehensive theoretical analysis of the hardware and the software of this system, This article emphatically elaborates data gathering, transformation, wireless communication, digital display in the design process. Simultaneously, using C51 software carries on the program monitoring to system each link.This design has achieved intelligent and digital requirements of the temperature detection,which has good practical application and economic effects.
