Remote control method and device for intelligent telephone

Abstract

The technical scheme of present invention is as the follows: detecting ring stream signal and counting by ringing detection and count circuit, activating off-hook and hangup control circuit by monolithic computer according to counting, inputting password by the user and signal being obtained by DTMF signal transceiving and signal determining circuit for decoding and sending to monolithic computer, control being reealized for household electrical appliances by push-button signal being sent to circuit of the network node interface via monolithic computer if authentication of user status is passed, dialing to be carried out by reading out phone number from information access circuit if user bus is at alarm signal and alarm operation to be finished by voice clue circuit.

Description

technical field [0001] The invention relates to a telephone remote control method and device, belonging to the field of remote communication. Background technique [0002] In the existing telephone remote control technology, the on-off control of the power supply is usually completed by using a telephone ringing signal or connecting with a single-chip microcomputer to drive a controller or using a relay. These control methods have certain shortcomings to varying degrees. For example, the patent application number 99257923.6 uses simple ringing current detection for control, and has neither voice prompts nor password protection and automatic off-hook and on-hook functions. The patent application number 96241401.8 uses a telephone to control the power switch of the remote control electrical appliance. There is also no voice prompt and password protection, which is easy to cause misoperation and the system security is very poor. The technical solution proposed by the patent N...

Problems solved by technology

The patent application No. 96241401.8 uses a telephone to remotely control the power switch of electrical appliances. There is also no voice prompt and password protection, which is easy to cause misoperation, and the security of the system is very poor.

The technical solution proposed by the patent No. 01206368.1 requires the power supply of the controlled electrical appliance to be connected through the telephone control module for control. This approach has certain dangers. On the one hand, accidents may easily affect the controlled electrical appliance, and on the other hand, it may be damaged. The equipment of the telephone exchange has an impact on the telephone network
