摘要
本文设计了一种以FPGA为控制核心的小型车库自助管理系统,辅以按键、LCD屏、付费模块和GPRS通信模块,实现对车辆入库、出库、停车计时收费等的管理。充分利用FPGA的片内存储器资源,对入库车辆信息进行记录,并产生标志位信息;车辆出库后,清除标志位,并对非连续存储空间进行管理;根据入库时间所产生的伪随机数,产生车辆出库密码,同时将相应信息发送到车主手机中。系统具有小巧、灵活、低功耗、低成本、通用性及可扩展性强等特点。
In this paper,a small garage self-service management system based on FPGA is designed,which is supplemented by keys,LCD screen,payment module and GPRS module to realize the management of car storage,parking and charging.FPGA on-chip memory resources are used to record the information of the vehicles,and produce corresponding flag bit.After the cars are out of storage,the flag bit is cleared.Further non-continuous memory space is managed.According to the storage time,pseudo-random number is generated as the car out-storage password,and sent to the owner's mobile phone number.The system has the characteristics of miniaturization,flexibility,low power consumption,low cost,high versatility and scalability.
