摘　　要：针对系统内含有DSP (数字信号处理 )芯片的检测系统 ,提出了运用DSP芯片对传感器进行非线性校正的方法。与传统校正方法进行比较可以表明 ,此方法简化了设计 ,提高了通用性和灵活性。In this paper, a new method of non-linearity rectification of sensor based on DSP(digital signal processing) chip, is put forward in the measurement systems. With comparison to traditional non-linearity rectification methods, this new method not only simplifies design, but improves generality and flexibility.And the feasibility of this new method, by adopting least square method to fulfill non-linearity rectification based on DSP chip is validated.
