英文摘要：

A smart digital compensation system based on ZMD31050,which was a chip used to the precise smart compensation for sensors,was developed for enhancing the precision of piezoresistive sensors on condition of wide temperature range.Sensor and its peripheral devices was abstracted as mathematical polynomial by polynomial fitting to eliminate the error.Its principle and features,the hardware,communication protocol and software of the system was introduced.The experiment results show that the system has the features of stable data transmission and production efficiency which can reach the requirement for the small quantities smart compensation of piezoresistive sensors.
