Measurement and Realization of Signal Sampling in the Control System of Charge Evasion in Medical Equipment
Yan Jun Zhou · Modern Electronics Technique · 2006
The control system of charge evasion in medical equipment is to control the irregularities in the hospital.The most important part is the signal sampling in the system.This article dwells on the projects of signal sampling,and mainly on the solutions of signal interruption and the idealized realization of signal sampling in the system with the weigh sensors EB9172 acting as the signal sampling source and INA125 instrumentation amplifier as the signal amplifier,setting the value of sampling frequency at multiple times of 50,adding zero-circuit and changing the general resistances to the sophisticated ones with sampling one set of the data in 20ms.
