基于GPRS的智能药品分拣装置设计 摘要 近年来，人们生活水平不断提高，逐渐出现了许多因为没有合理膳食，也缺乏适量运动引发的慢性常见病。随着看病人群数量的急剧增多，由于医院药房工作人员要根据病人递给的药单逐个地找药和取药，效率低，所以经常在医院看到这样的情形：人们在取药的窗口排很长的队伍，等待取药。 本毕业设计针对上述问题，为提高医院药房工作人员的效率，设计实现了一种智能药品分拣装置。本设计实现的装置由触摸屏、GPRS通信模块、西门子S7-200PLC、药品架等组成。该智能药品分拣装置可接收医院医疗信息服务器的处方信息，快速指导工作人员找到处方药品，发放给病人，大大缩短了药房工作人员的取药时间，节省了患者等待的时间，并且能够避免在取药过程中人为造成的取错药问题。 关键词：西门子S7-200PLC 触摸屏 GPRS通信 药品分拣 Design of an intelligent drugs sorting device based on GPRS Abstract In recent years, peoples living conditions continue to improve. Gradually people who take too high calorie food and lack exercise are suffering from some common chronic diseases. The number of medical people is increasing sharply. The hospital pharmacy staffs need take medicine and get medicine to a patient one by one according to the prescriptions. So the efficiency is low. Often in the hospital the lines of people who are waiting for getting medicine are long. In order to solving the above problems, this design produced an intelligent sorting device. The device is composed of a touch screen, a GPRS DTU module, a SIEMENS S7-200PLC, medicine cabinets. The intelligent sorting device can receive the information of prescription from the hospital server, and quickly guide the staff to find the drugs. Then the drugs can be provided to the patient. The time of taking medicine can be shorten by using this device. And the waiting time of the patient can be saved too. Particularly during the process of taking the medicine, the problem of taking the wrong medicine can be avoided.
