Abstract:
AIM:To design a signal collecting system of urethral internal pressure based on embedded microprocessor(ARM).METHODS:Based on ARM,the signal collecting module of urethral internal pressure and signal amplifier circuit were designed with sensor technology.The A/D transition circuit was improved by signal feedback theory to increase measurement accuracy.The software of sensor temperature drift was rectified by second linear interpolation so to enhance the accuracy of data collection.RESULTS:In simulated static urethral internal pressure collection,the signals of urethral internal pressure that sensor collected were corresponded with the location completely and send them into RAM of ARM for following analysis.CONCLUSION:The ARM-based signal collecting system of urethral internal pressure has simple circuit,reliability,lower power consumption,high precision and strong spot data analysis.
