Description

Radio frequency communication method of wireless remote control equipment and computer equipment Technical Field The present application relates to the field of wireless radio frequency communications, and in particular, to a method and a computer device for radio frequency communications of a wireless remote control device. Background The wireless remote control device is widely applied to the scenes of industrial remote control, unmanned aerial vehicle control and the like, and transmits user instructions through radio frequency communication. In the prior art, the equipment starting process has defects, such as error triggering operation when a rocker or a key is not reset due to zero position verification of an operating component being ignored in an initialization stage, potential safety hazard is increased, and communication interruption is easily caused due to failure in initialization of a radio frequency module or insufficient detection of channel conflict. In the main circulation operation interface, a fixed period strategy is adopted for collecting operation data such as key states and rocker positions, whether user input is needed or not cannot be distinguished, redundant data are sent at high frequency when the user is not in operation, energy consumption is increased, and real-time performance is affected by response delay when the user is in operation. The fixed rate is used when the radio frequency data packet is sent, so that the radio frequency data packet can not adapt to dynamic scenes and the efficiency is reduced. The receiving end responds to weak verification mechanism of the data packet, such as machine code matching and verification missing, so that invalid data is processed, connection state is misjudged, and the stability of the device is poor in a weak signal environment. These problems are highlighted by high power consumption, slow response, low reliability, and a solution integrating intelligent initialization, adaptive rate and tight verification is needed. Disclosure of Invention In order to solve the problems of unsafe starting, low efficiency, fixed speed and weak verification of the existing wireless remote control equipment, the application provides a method for radio frequency communication of the wireless remote control equipment and computer equipment.

By adopting the technical scheme, the basic reliability of the wireless remote control equipment is ensured by integrating the initialization and safety starting processes, the input data and the state of the operation component are collected according to the preset period in the main circulation operation interface, and the real-time operation response is realized. By dynamically selecting the transmission rate of the radio frequency data packet, the input state change of the operation component is adaptively matched, the radio frequency transmission efficiency is optimized, and the energy consumption is reduced. The stability and fault tolerance of the communication link of the wireless remote control device are enhanced by combining the validity analysis of the radio frequency response data packet and the updating mechanism of the connection state. The whole flow effectively improves the man-machine interaction instantaneity, the energy efficiency ratio of data transmission and the robustness of the system, reduces the interaction link of the redundant protocol, and obviously reduces the response delay and the resource occupation of the system. Optionally, the step S1 includes executing a power-on and self-checking process of the wireless remote control device, including running of an indicator light and screen display information, executing zero check of an operation part, ensuring that all the operation parts are released and located at an initial position, wherein the operation part comprises a key, a dial button and a rocker, initializing a radio frequency module and executing channel conflict detection.
