摘　　要：医疗设备漏费控制系统是为了对医院检查中出现的违规现象进行控制。该系统中的信号采集部分是系统设计的关键。对信号采集的方案进行研究,并着重阐述以称重传感器EB9172为信号采集源,以INA125仪表运放为信号放大器的信号采集方案,并在应用中采取将采样频率设置为50的倍数、一组数据采样时间为20 ms,增设调零电路和将普通电阻换为精密电阻等措施解决了信号干扰问题,较好地实现了系统中信号的采集。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 sampiing one set of the data in 20ms.
