Early warning method, apparatus and device for tumbling during riding

An early warning apparatus for tumbling during riding, the early warning apparatus for tumbling during riding comprises:

• an acquisition module, configured to monitor a target rider during riding at a preset frequency via a GNSS positioning module, and obtaining a first riding velocity, meanwhile, monitoring the target rider at the preset frequency during riding via a six-axis inertial measurement unit module and obtaining a second riding velocity and acceleration data;
• a monitoring module, configured to monitor a communication status of the GNSS positioning module, and monitoring in real time the first riding velocity where the communication status of the GNSS positioning module is regular;
• a computation module, configured to analyze the acceleration data, where the acceleration data satisfy an interval of a preset first threshold, executing the step S4, where the acceleration data do not satisfy the interval of the preset first threshold, executing the steps S1 to S3 repeatedly;
• a broadcasting module, configured to give threshold analysis to the first riding velocity in a preset time interval, meanwhile, giving riding gesture analysis to the target rider, and obtaining the riding gesture data, where the first riding velocity satisfies an interval of a preset second threshold, pronouncing a warning to the target rider via a loudspeaker module, meanwhile, collecting in real time operation data of the target rider, where the first riding velocity does not satisfy the preset second threshold interval, or the riding gesture data are regular, executing the steps S1 to S4 repeatedly;
• and
• an early warning module, configured to send assistance request data to a preset remote server where the operation data of the target rider are not collected, and send the assistance request data to a plurality of riders in a target area via a Mesh network, wherein the assistance request data comprise positional information of the target rider.
