Abstract

The utility model provides a long-range controller of telephone with preset numbers, comprising a high-speed memory circuit with preset numbers and codes 2 and a monolithic computer signal recognition, process, control circuit 1. The high-speed memory circuit is connected with a monolithic computer. The input end of the monolithic computer 1 is respectively connected with the output end of a ringer signal detection circuit 3 and the output end of a dual-tone multi frequency signal demoding circuit 7. The outlet of the monolithic computer 1 is respectively connected with an analogous off-hook circuit 3, a sound monitoring circuit 5, and a controlled object control end. The high-speed memory is cooperated with the monolithic computer. A plurality of sets of presetable phone numbers and long number codes can be preset and stored by the telephone key to compare with and identify the identity of the calling party through the incoming call number. If the comparison and the identification is correct, the code inputted by the calling party is carried out the comparison and the identification again. If the comparison and the identification is correct, the control command generated by the calling party can be accepted so that the controlled circuit can perform the associated control program. The utility model which has the advantages of compact circuit structure, reliable remote control, good security can carry out the remote control for the mobile device.

Description

A kind of preset number remote telephone controller

Technical field

The utility model relates to the remote control technology field, particularly a kind of preset number remote telephone controller.

Background technology

Landline telephone of China and mobile phone all have and build full basic network facility at present, bring great convenience for people's communication, on the other hand, rhythm of life is accelerated or because the field condition restriction because people work, people usually need to carry out place remote control to dwelling house, household electrical appliance and some industrial electrical equipment equipment etc., and method commonly used has methods such as infrared wireless remote control, private cable transmission control.The remote control end of infrared wireless remote control and controlled end adopt infra-red code reflector, infra-red code receiver, coding circuit, wireless transmission circuit to form.This method command range is restricted, and the scope of transmitting and receiving has only about 500 meters, and unsuitable farther distance is promoted.Private cable transmission control, though the control effect is better, because the cable laying cost is too high, too tired lock also should not be promoted.

Summary of the invention

The purpose of this utility model provides a kind of reliability height, the preset number remote telephone controller of strong security.

Said preset number remote telephone controller comprises telephone set 4, ringing signal test circuit 3, simulation circuit for answering 5, touch-tone signal decoding circuit 7, monitoring circuit 5, it is characterized in that: further comprising the high-speed memory circuit 2 that stores preset number and password and the identification of single-chip microcomputer signal, processing, control circuit 1.High-speed memory circuit 2 is connected with single-chip microcomputer 1; The input port of single-chip microcomputer 1 is connected with the output of ringing signal test circuit 3, the output of touch-tone signal decoding circuit 7 respectively; The delivery outlet of single-chip microcomputer 1 is connected with 8,9,10,11 control input end of simulation circuit for answering 3, monitoring circuit 5, controlled object respectively.

Described high-speed memory circuit 2 cooperates with single-chip microcomputer 1, can press key assignments by telephone set 4 and store many group presetting number of cell phone and organize the long number passwords more, with the identification of comparing of calling party's caller ID.As it is correct to compare identification, to the identification of comparing of the password of calling party's input, correct as comparison identification again, then can receive the control command that the calling party sends, and makes controlled circuit 8,9,10,11 carry out the control program of being correlated with.Described high-speed memory circuit 2 inside are provided with watchdog timer and voltage monitor cooperates the task of can also finish the data preservation that is provided with after the power down, the task that resets and low-voltage detection protected data with single-chip microcomputer.

The signal input P3.0 of described single-chip microcomputer 1 is connected with circuit ringing signal test circuit 3 with the telephone line off-hook detection by photoelectrical coupler, when the telephone set off-hook or receive that the bell signal single-chip microcomputer counts it, and after reaching the ringing number of regulation, low transition by P3.1, realize the simulation off-hook through simulation circuit for answering 5, single-chip microcomputer is also in time received the double-audio signal data on double-audio signal decoding circuit 7 data terminals, and with the preset number identification of comparing, as discern correct, send identification and pass through prompt tone, the calling party inputs password after hearing the prompt tone that is sent by single-chip microcomputer P3.1 mouth by monitoring circuit 6 again, the single-chip microcomputer identification of comparing once more, after the calling party correctly inputs password, just can be by the button of remote phone machine, import different numerals and carry out straighforward operation, finish different control tasks.

The beneficial effects of the utility model are: circuit structure is succinct, Long-distance Control is reliable, good confidentiality, and can implement Long-distance Control to mobile device.
