基于FPGA的小型车库自助管理系统设计

摘要

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.%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.
