Parking lot's parking stall data transmission system

The invention belongs to the wireless serial port communication field and more particularly, to a parking lot's parking stall data transmission system comprising a data frame protocol module and a local network structuring module and characterized by: the data frame protocol module is used for the data forwarding and communicating between a master machine and a slave machine and the local network structuring module is used to detect the master machine and to connect the slave machine to automatically develop a tree topology network. The system of the invention solves the problem that reliable communications of a simply structured network through wireless serial ports could hardly be possible in a complicated indoor environment. 本发明属于无线串口通信领域领域，特别涉及种停车场车位数据传输系统。包括数据帧协议模块和区域网络组建模块，其特征在于：所述的数据帧协议模块用于主机和从机数据转发通信，区域网络组建模块用于主机探测和连接从机，自动组建树形拓扑网络。本发明解决了无线串口简单组网在复杂室内环境下难以可靠通信的问题。
