一种便携式自动售卖药箱控制系统的设计与仿真

Design and Simulation of a Control System for Portable Medicine Vending Machines

设计了一款实时监测电池电量和药品数量的便携式自动售卖药箱控制系统。该系统主要由蓄电池、压力传感器、信号采集与传输、主控单元、cat1等模块组成,主控单元通过采集压力传感器的输出电压和电池电压来判断药箱的电池剩余电量和剩余药量,并通过cat1模块将结果发送给经营者。并采用LabVIEW与Multisim联合技术对该系统进行仿真,仿真结果表明该系统能够有效地完成对电池电量和药品数量的实时监测,同时具备上货和系统异常关闭的功能,可有效应用于便携式自动售卖系统中。

In order to solve the problem that the battery of the medicine vending machine cannot be replaced and the medicine cannot be replenished in time,a real-time monitoring system is designed,which is mainly composed of battery,pressure sensor,signal collection and transmission,main control unit and cat1 modules and so on.The main control unit can measure the remaining quantityin the medicine box and the remaining power of the battery by collecting the output voltage of the pressure sensor and the battery.When the remaining amount of medicine or battery power is low,the information is sent to the operators through the cat1 module.The system is simulated by the co-simulation function provided by LabVIEW and Multisimwith results showing that this system can effectively monitor battery’s power and the amount of the medicine in real time.With the additional functions of loading and shutdown system for abnormality,this system can be effectively applied to the portable vending machines.
