The invention relates to the technical field of intelligent garages, and discloses a communication method for master and slave controllers of an intelligent garage, in the communication method, the master controller wirelessly communicates with all slave controllers in a broadcast form, and since path selection is not needed, the wireless communication cost is reduced; in addition, the main controller is arranged to circularly send data, the data comprise control instructions and heartbeat data, all the slave controllers send input port state information and output port state information of the slave controllers to the main controller after receiving the data sent by the main controller, and information return is achieved. Therefore, the main controller can know the state information of the parking spaces of the whole garage in real time, and normal operation of the intelligent garage is ensured.
本发明涉及智能车库技术领域,公开了一种用于智能车库的主、从控制器的通讯方法,在本发明的通讯方法中,主控制器通过广播的形式与所有的从控制器无线通信,由于不用路径选择,因此其无线通信成本得到了降低;另外通过设置主控制器循环发送数据,数据包括控制指令和心跳数据,以及让所有的从控制器在接收到主控制器发送的数据后便将自身的输入端口状态信息和输出端口状态信息发送给主控制器,实现信息回传,进而能够使主控制器实时了解整个车库的车位的状态信息,确保智能车库的正常运行。
