Method for realizing remote simulation key control based on telephone

The invention relates to a method for realizing remote simulation key control based on a telephone. The telephone is connected with controlled equipment by a network based on a VoIP (Voice over Internet Portocol). In the method, according to keys, the telephone utilizes an RFC2833 way to transmit DTMF (dual-tone multifrequency) codes to the controlled equipment by a VoIP network, and then the controlled equipment conducts the simulation key control according to the DTMF codes. As the fault tolerance and the identification error rate on packet loss are low in the transmission way, the method for realizing the remote simulation key control can effectively ensure the accurate transmission of control information, and realizes the continuous regulation control on various simulation quantities.For the method for realizing the remote simulation key control, the implementation cost is low, the application method is simple and convenient, and the application range is wider.
