Bluetooth-based ranging wheel data transmission method and system

The invention relates to the technical field of distance measuring wheels, in particular to a distance measuring wheel data transmission method and system based on Bluetooth. The method comprises the following steps: acquiring survey data information of a ranging wheel; a Bluetooth chip and a 7442B chip are arranged on the distance measuring wheel; the survey data information of the distance measuring wheel is preprocessed based on a 7442B chip; establishing a Bluetooth Mesh network based on a Bluetooth chip on the distance measuring wheel; data communication between the distance measuring wheel and the receiving equipment is carried out through the Bluetooth chip and the Bluetooth Mesh network; and receiving survey data information of the distance measuring wheel by using a receiving device, extracting distance and speed parameters, and performing data display. And the wireless connection between the distance measuring wheel and other equipment can be realized by transmitting data through Bluetooth. Compared
