Triple Password Proximity-Interrogative Smart Fob Switching Of Electrical Device

摘要

A smart module for actuating an electrical device in response to a smart fob includes: a low frequency transmitter for transmitting a first password and a smart module ID number in a low frequency signal; an auto-polling timer controlling a length of time between transmissions of the first password and the smart module ID number over a predetermined time frame; a high frequency receiver for receiving a high frequency signal including a second password; a memory for storing a registration number with which the smart fob is registered to the smart module, a smart module ID number for the smart module and a third password; a sending unit connected to the electrical device; and a processor for decrypting the second password and determining if the second password is from the smart fob registered to the smart module and then sending the third password to the electrical device via the sending unit if the second password is from the smart fob registered to the smart module.
