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

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

In the prior art, variable resistors are often connected in the circuit to adjust the resistance of the system, and in order to achieve the purpose of precisely adjusting the resistance, multiple variable resistors can be connected in series or parallel to better meet the requirements of the system. However, this low-cost, easy-to-use, and precisely adjusted load regulation circuit has not been applied in the field of telephone remote control.
