However, the existing electric tricycle bluetooth binding technology still has a plurality of defects to be solved urgently, and the requirements of safety and accuracy in practical application are difficult to meet: 1. The production end data association accuracy is insufficient, namely in the prior art, the Bluetooth hardware information (such as Bluetooth MAC address) of the alarm is only associated with the frame number in a single dimension, a double check mechanism of a production station level is lacked, and a three-dimensional mapping data system of 'Bluetooth MAC address-equipment SN code-frame number' is not established. In the production process, data binding errors are easily caused by manual error scanning, station crossing operation and the like, meanwhile, collected data are transmitted and stored in a non-encryption mode, the risk of data leakage or tampering exists, and potential safety hazards are buried for subsequent binding flow. 2.
