基于STM32的共享车位锁系统设计

Design of shared parking lock system based on STM32

该系统以STM32为核心控制芯片,结合GSM、无线串口、超声波测距等模块设计外围电路,实现了车位锁网上预约、APP控制锁体升降、防撞报警、计时收费等功能。采用中容量的STM32芯片作为控制核心,缩小了控制板体积,降低了成本,减小了系统功耗。在同一区域内,各车位锁之间通过无线串口模块相互通信,以一主多从的模式工作,进一步缩减了系统成本,简化了系统结构。最后搭建实物平台并实验验证,得到了较好的控制效果,证明了该方案的可行性。

The system based on STM32 core control chip, combining with the GSM, wireless serial port, and like ultra- sonic ranging module design of peripheral circuit, has achieved the parking locked online ordering, APP control lock body movements, anti-collision alarm, timing charging, etc. The medium-density performance line STM32 chip is used as the control core, which reduces the volume of the control panel, reduces the cost and reduces the power consumption of the system. In the same area, each parking lock communicates with each other through the wireless serial port module, and work in a multi slave mode, which further reduces the system cost and simplifies the system structure. Finally, the physical platform is set up and verified by experiments, which proves the feasibility of the scheme.
