Abstract

The invention discloses a dual-mode Bluetooth-based data transmission system and a dual-mode Bluetooth-based data transmission method in an underground tunnel. The method comprises the following steps: a plurality of sets of Bluetooth equipment mounted in the underground tunnel in a spacing manner broadcast in an intermittent manner under a BLE (Bluetooth Low Energy) mode; a mobile terminal in the underground tunnel searches the Bluetooth equipment under the BLE mode in an automatically intermittent scanning manner, and establishes a communication link with the searched Bluetooth equipment; the mobile terminal sends an instruction for switching to an SPP (Serial Port Profile) mode to the Bluetooth equipment establishing the communication link with the mobile terminal; the Bluetooth equipment establishing the communication link with the mobile terminal makes a response after receiving the instruction for switching to the SPP mode and shuts off the BLE mode; the mobile terminal establishes a communication link with the Bluetooth equipment under the SPP mode, transmits acquired data to be transmitted to a server through the Bluetooth equipment under the SPP mode; and the server transmits the data to a target client.

Description

technical field [0001] The invention belongs to the technical field of bluetooth transmission video, and in particular relates to a data transmission system and method based on dual-mode bluetooth in an underground tunnel. Background technique [0002] At present, my country is increasing the investment and construction of underground comprehensive pipe corridors, investing trillions every year to build thousands of kilometers of underground comprehensive pipe corridors. However, many underground pipe galleries do not provide strong electricity or mobile phone signals for safety reasons. After construction inspection personnel enter the tunnel, they cannot communicate with the outside world, which seriously reduces the work efficiency of construction inspection personnel. The problem of high-speed communication with power consumption has become a difficult problem for underground pipe gallery builders. [0003] Since WiFi communication consumes too much power compared to Bl...
