The invention discloses a method and a device for acquiring empty parking spaces of a parking lot based on LoRaWAN. The method comprises the following steps: placing a device for acquiring the empty parking spaces of the parking lot based on LoRaWAN on each parking space in the parking lot; before use, the number of each parking space is set and stored in the Flash of the LoRa communication module, and the number and parking space information form a data packet; in the aspect of hardware design, the size of a module is reduced, the cost is reduced, a radio frequency circuit is designed and optimized, the anti-interference capability is improved, and the performance of a radio frequency chip is fully exerted. A LoRa network is established in a parking lot, a LoRaWAN 1.0.3 protocol stack is taken as a communication basis, network access is performed in a ClassA operation mode, low power consumption of a LoRaWAN is fully exerted, information of a sensor is acquired by taking an IIC/UART as an interface, parking space information is judged, a LoRa module sends the information acquired by the sensor to a LoRaWAN gateway and forwards the information to a server, and a background application of the parking lot can acquire the parking space information by accessing the server. Therefore, the parking space condition can be known in real time, and parking space information can be fed back to a vehicle owner.

    本发明公开了一种基于LoRaWAN获取停车场空车位方法和设备,包括以下步骤:在停车场中的每个车位上放置一个基于LoRaWAN获取停车场空车位设备;在使用之前设置好每个车位编号存储在LoRa通信模块的Flash中,将编号和车位信息组成一个数据包;本发明在硬件设计方面减小模块的尺寸,减少成本,设计优化射频电路,提高抗干扰能力,充分发挥射频芯片的性能。在停车场内组建LoRa网络,以LoRaWAN1.0.3协议栈为通信基础,以ClassA运行模式入网,充分发挥LoRaWAN的低功耗,以IIC/UART为接口获取传感器的信息,判断车位信息,LoRa模块将传感器获得信息发送至LoRaWAN网关转发至服务器,停车场的后台应用可通过接入服务器获取车位信息,则可实时了解车位情况,并向车主反馈车位信息。
