Abstract

The invention discloses an RF communication method and an RF communication device. The RF communication method in an embodiment comprises the steps of: sending a first request message to a second RF communication terminal, wherein the first request message comprises an initial identification code; receiving a first response message sent by the second RF communication terminal after the first request message passes verification, wherein the first response message comprises a first random code generated by the second RF communication terminal randomly; adopting a preset information processing method for processing the first random code to obtain a first identification code; sending a second request message to the second RF communication terminal, wherein the second request message comprises the first identification code; and carrying out security verification by the second RF communication terminal according to the first random code and the first identification code. The RF communication method and the RF communication device achieve the security of RF communication easily at low cost, and can effectively prevent malicious intrusion.

Description

technical field [0001] The invention relates to the field of radio frequency communication, in particular to a radio frequency communication method and a radio frequency communication device. Background technique [0002] Distribution network automation feeder terminals (referred to as feeder terminals) are used to control the switches of distribution network feeders. They are usually scattered and installed in inconvenient places in the field or in scattered locations in the city. The installation locations are usually located on distribution network poles, which is not conducive to installation and Maintenance personnel operate and maintain at close range. The feeder terminal with radio frequency communication function has the ability of wireless communication, and can communicate with the portable remote control device that also has radio frequency communication function via radio frequency signals. By operating the portable remote control device, functions such as data c...
