摘　　要：针对医院停车拥堵时可进行应急收费,研发了一台基于ARM Cortex微控制器的便携式无线票据打印机。该打印机通过可充电锂电池提供电量,并由蓝牙模块与主系统实时交互进行无线通信,其以ARM Cortex微控制器为主控,变电器、伺服电机为执行器,触摸屏作为通信上位机,实时监控整个运行过程。出于对便携打印的效率和稳定性方面的考虑,进行仿真测试。实验结果表明,该便携式无线票据打印机在逆变高跳变的动态负载情况下依然能够输出稳定的直流电压进行工作,且在待机时具有较低的功耗。Aiming at emergency charges when parking congestion in hospitals,a portable wireless receipt printer based on ARM Cortex microcontroller has been developed.The printer provides power through a rechargeable lithium battery,and the bluetooth module performs real-time interactive wireless communication with the main system.The ARM Cortex microcontroller is the main control,the transformer and the servo motor are the actuators,and the touch screen is used as the communication host computer to monitor the entire operation process in real time.In consideration of the efficiency and stability of portable printing,perform simulation tests.Experimental results show that the portable wireless receipt printer can still output a stable DC voltage to work under the dynamic load of inverter high-jumping,and has low power consumption during standby.
