Abstract
This paper designs a multi-channel temperature acquisition system based on DSP , which is used to collect and process multi-channel temperature data . Using the LM35 temperature sensor and DSP chip , and combining with related programs and software , the system realizes the multi-channel temperature data acquisition and processing . The hardware circuit is simple , at the same time , comparing with the single chip microcomputer data acquisition system , it can satisfy the accuracy and real-time re-quirements of the data acquisition system . Experiment proves that the system has good real-time performance , convenience and safety , which can be used in the most of the real-time temperature acquisition in the field of industry and agriculture .关键词
