The remote monitoring system based on DTMF Technology
Abstract：In twenty-first Century the information era of globalization, communications and electronics industry can be said to have been great development, so with the development of society, along with the technical and economic level of continuous progress, with the accelerated pace of life, people began to pay more and more attention to the intelligent and remote control of various household appliances, remote control and monitoring of implementation household appliances will become indispensable to people's life demand.
Therefore, this thesis is to investigate a remote monitoring system, this system is composed by the wired telephone network and mobile telephone terminal, remote access terminal using mobile phone case, for any telephone line network, control range can be achieved, and the system has good applicability.
In order to realize the remote control of all kinds of home appliances, this paper discusses the remote controller, designed a system controlled by STC89C52 single-chip microcomputer, the system is implemented by telephone DTMF (DTMF) signal to complete the remote control of home appliances, the control system are discussed. In detail, also expatiate on the chip, system module, hardware configuration, software design and its working principle and function introduction.
Keywords:Phone remote monitoring Household appliances
