| Abstract: |
| Based on the principle of carrier communication,an intelligent control system is presented,which applies single chip microcomputer and DTMF(Dual Tone Multi Frequency) coding technique to realize remote control of objective load. The principle of carrier data transmission is introduced,as well as the characteristics of DTMF coding. The hardware design,module configuration and pro-gram flowchart of software design are given. Measures of interference rejection are proposed. The test results show that the control system is stable and reliable,and meets the requirement of carrier control with power line. |
