The embodiment of the invention discloses a multi-agent ZigBee communication method supporting the MavLink protocol, relates to the technical field of unmanned aerial vehicle mobile communication, and can solve the problem of data channel blockage when Zigbee transparent mode is applied to multi-agent cluster communication. The invention includes: one multi-agent corresponds to one communication controller, and the communication controller receives / sends data packets in the MavLink protocol format to realize information interaction between the multi-agents; a time synchronization method is designed to realize the communication synchronization of multiple communication controllers, each A communication node can only send data at a specified time, thereby avoiding data communication conflicts and improving the performance of the ZigBee communication network in transparent mode. The invention is suitable for formation communication networking among unmanned aerial vehicles supporting the MavLink protocol by using the ZigBee wireless communication module.

A rebar mechanical anchoring method relates to rebar mechanical anchoring and belongs to the field of constructional engineering. The rebar mechanical anchoring method avoids over-length rebar anchoring length and particularly avoids over-length anchoring length of high-strength longitudinal stress rebar. The rebar mechanical anchoring method solves the problem that welding speed is slow and welding quality is difficult to guarantee due to the fact that a welding mode is used for welding the rebar and an anchoring plate, solves the problem that hook anchoring of the tail end of the rebar has influences on pouring of concrete and an anchoring is crowded, and solves the problem of damage to partial concrete easily occurred in tail end anchoring. A steel sleeve is sleeved outside the rebar, an extrusion device is used for conducting radial extrusion on the steel sleeve to enable the steel sleeve to have plastic deformation to be meshed with a rebar transverse rib to form a whole to form anchoring, multi-point anchoring is formed by setting a plurality of steel sleeves in a rebar anchoring length scope to increase anchoring force, and compared with a method of forming anchoring at the tail end, the anchoring length of the rebar is about 40% of basic anchoring length equivalently. The rebar mechanical anchoring method has wide application prospect on the constructional engineering.
