Wireless radio frequency module serial communication method used for remote control device

Abstract

The invention relates to a wireless radio frequency module serial communication method used for a remote control device. The wireless radio frequency module serial communication method comprises connection confirmation, including, sending a connection request instruction frame to a target slave machine by a host, and replying to confirm a connection instruction frame to finish connection confirmation of the host and the target slave machine after the target slave machine receives the connection request instruction frame; data transmission, including, after connection confirmation, sending a data frame to the slave machine by the host, and receiving the data frame by the slave machine; and state checking, including, when the number of the target slave machine is 1 and after a set number ofthe target frames are set at each time, performing connection confirmation for the host and the slave machine by the host. In comparison with the prior art, when the number of the target slave machineis 1 and after the preset number of the data frames are sent at each time, connection confirmation between the host and the slave machine is carried out by the host; and when the host performs directed transmission on one slave machine, high-reliability automatic reconnection between the host and the slave machine is realized through the instruction frame under the condition that a signal is recovered after being lost.

Description

technical field [0001] The invention relates to a communication method, in particular to a serial communication method of a wireless radio frequency module used for remote control equipment. Background technique [0002] Serial communication technology has always been a widely used technology in the field of communication. Serial communication is easy to set up, low in construction costs, and flexible in use. It is suitable for many occasions that require simple communication. However, the serial communication rate is low and the anti-interference is not strong. In the complex communication environment, the usability of serial communication is not good, and it is easy to have errors and packet loss. cause serious impact. [0003] During the communication process between the master and the slave, because the communication between the remote control devices usually works in an unstable situation, it is greatly affected by the signal strength and signal interference, and disco...
