The invention provides an outdoor wireless communication system based on a LoRa ad-hoc network, which is used for solving technical problems of poor mobile network signals in severe environment, short transmission distance and absence of an interactive interface for information sharing of the existing outdoor wireless communication system. The outdoor wireless communication system based on the LoRa ad-hoc network comprises a central processing unit, a positioning module, a Bluetooth module, a peripheral interface, a power supply module, a LoRa communication module and a mobile phone APP terminal; the central processing unit is respectively connected with the positioning module, the Bluetooth module, the peripheral interface, the power supply module and the LoRa communication module; the LoRa communication module constructs a wireless Mesh network with the LoRa communication modules of other systems, and performs reliable data communication through a CSMA/CA protocol and an AODV routing algorithm; and the mobile phone APP terminal and the Bluetooth module perform data exchange through the Bluetooth. The outdoor wireless communication system based on the LoRa ad-hoc network performs communication without the mobile network, has long transmission distance, has the interactive interface for information sharing, and can be applied to the fields, such as the Internet of Vehicles and the Internet of Things.
