Method and system for patrolling an expressway by unmanned aerial vehicles

A system for patrolling an expressway by unmanned aerial vehicles (UAVs), comprising a control center, a plurality of UAVs and a plurality of advertising board charging base stations;

• wherein the control center comprises:
• an analysis module, configured to receive UAV status information sent by a plurality of UAVs, classify the received UAV status information, and perform analysis respectively according to categories of the UAV status information to obtain status results corresponding to the plurality of UAVs;
• and
• a processing module, configured to generate and send corresponding control instructions to the plurality of UAVs according to the status results corresponding to the plurality of UAVs;
• wherein, each of the plurality of UAVs comprises:
• a reporting module, configured to send status information to the control center such that the control center classifies the received UAV status information and performs analysis respectively according to the categories of the UAV status information to obtain status results corresponding to the various UAVs;
• and
• an execution module, configured to receive control instructions generated and sent by the control center based on the status results, and execute task commands carried in the control instructions;
• wherein, each of the advertising board charging base stations comprises:
• an advertising board body, distributed along the roadside of an expressway;
• a charging platform, disposed on the advertising board body, wherein at least one UAV charging pile is arranged on the charging platform, and the charging pile is powered by a power supply carried by the advertising board body;
• a communication unit, disposed on the advertising board body and configured to establish a communication connection with the UAV and the control center to send advertising board charging base station information to each of the UAVs and the control center,
• wherein the categories of the UAV status information comprise:
• a to-take-off state category, which is a category of UAV status information indicating that an UAV is stopped on a designated advertising board charging base station and has a power exceeding a preset threshold value;
• a patrolling state category, which is a category of UAV status information indicating that an UAV is executing patrolling task and does not complete this task,
• a to-land state category, which is a category of UAV status information indicating that an UAV has completed the patrolling task and does not land,
• a charging state category, which is a category of UAV status information indicating that an UAV is stopped on a designated advertising board charging base station and has a power not exceeding a preset threshold value;
• and
• a pre-warming state category, which is a category of UAV status information indicating that an UAV is deviated from preset flight path points by an amount greater than a preset threshold value or the own power is not enough to allow the UAV to land on a designated advertising board charging base station.
