Description

The telephone remote control of multi-path digital coding, wireless operating

Technical field

The utility model relates to a kind of telephone remote control, specifically is that a kind of phone that utilizes carries out this machine of strange land dialing remote control, by the telephone remote control of digital coding wireless operating multichannel equipment opening and closing.

Background technology

Up to the present, its circuit of existing telephone remote controller mainly contains: bell flowing detecting circuit, simulation circuit for answering, DTMF decoding circuit, binary decoding distributor circuit, compositions such as drive circuit.During use, available landline telephone or mobile phone are dialed the landline telephone in strange land, connect and the collinear telephone remote control of this strange land phone phone, simulate off-hook according to the ringing-current number of times, and remote control circuitry inserts telephone line.The side of dialing dials the numbering that needs control appliance again, drives the adhesive or the separation of corresponding relays after the remote controller decoding more along separate routes, the control relevant device open or turn-off the purpose that reaches the strange land remote control.

This class remote controller has three shortcomings: is connected by power line between the one, remote controller and controlled equipment, and very inconvenient for using in the dwelling house, particularly for the dwelling house that has carried out finishing, increase many electric wires again, both inconvenience was not attractive in appearance yet, and very dangerous; Its two, during controlled equipment work, its remote controller needs charged for a long time, very unreasonable, also influences the life-span of remote controller; Its three, the method that control appliance opens or cuts out is science not, uses trouble easily to cause misoperation.Because the existence of above shortcoming influences the commercialization of this product.

Summary of the invention

In order to solve the shortcoming of foregoing circuit, the utility model provides a kind of electric wire that has removed between remote controller and the remotely-controlled equipment, and utilizes the RS latch cicuit, the digital coding-decoding circuit, and the wireless transmission receiving circuit reaches the telephone remote control of remote control strange land equipment.This remote controller is made up of one in main frame and some of subsidiary engines, main frame and landline telephone machine circuit also together, subsidiary engine can be inserted in the supply socket of the equipment of controlling, and the attaching plug of equipment can be inserted in the jack on the subsidiary engine panel.The side of dialing dials the number of landline telephone earlier during use, after remote controller detects bell ring, according to bell ring number of times simulation off-hook.The side of dialing dials the numbering of " 1 " (start) or " 0 " (shutdown) and relevant device again, remote controller is deciphered, by digital coding emission high-frequency wireless signals, after corresponding subsidiary engine is received signal, decipher and drive relay adhesive or separation and reach the open/close purpose of control appliance.

Telephone remote control of the present utility model, its invention main points are: unique controlled device machine open/close and decoded signal storage stepping circuit and multi-path digital coding and decoding wireless operating control circuit.

Controlled device machine open/close of the present utility model and decoded signal storage stepping circuit, mainly by DTMF double-tone frequency decoding circuit, four line binary decoding multichannel distributor circuits, RS latch signal storage stepping circuit is formed.

Multi-path digital coding and decoding wireless operating control circuit is by digital coding, high frequency wireless transmission and wireless receiving, and digit translation drives the relay two large divisions and forms.Multi-path digital coding radio transmitter part and controlled device machine open/close, decoded signal storage stepping circuit bank is fitted together as main frame, all circuit is by bell flowing detecting circuit, the simulation circuit for answering, the DTMF decoding circuit, four line binary systems, ten six tunnel decoding distributor circuits, decoded signal stepping circuit, multiaddress, multidata digital coding circuit, the high frequency radio transmitter is formed.The wireless receiving digit translation drives the relay part and puts together with institute control equipment, by high frequency wireless receiving module (supporting) with transmitter module, and multiaddress multidata digital decoding circuit, drive circuit and relay switch circuit are formed.The bell flowing detecting circuit of this machine, the simulation circuit for answering, power circuit and custom circuit indistinction are no longer introduced.

Operation principle of the present utility model is: the calling party is by strange land landline telephone or mobile phone, dial the number of the landline telephone in parallel with this remote controller, this remote controller receives ringing-current simultaneously, behind the certain number of times of bell ring, bell flowing detecting circuit sends signal and gives the simulation circuit for answering, the simulation circuit for answering drives relay, simulate off-hook, and send off hook signal to the calling party, DTMF decoding circuits etc. insert telephone line, at this moment the calling party can press the numbering (can only use " 2 "---8 numbers between " 9 ") of " 1 " or " 0 " (" 1 " representative start, shutdown of " 0 " table) and relevant device.After this remote controller DTMF decoding circuit receives that the first figure place sign indicating number of caller dials is deciphered, give A, B, C, the D pin of four line binary decoding distributor circuits by Q1, Q2, Q3,4 binary system binary-coded decimals of Q4 pin output, " 1 " or " 0 " pin output high level of this four lines binary decoding distributor circuit is given the first order RS latch R end, this latch " Q " pin output low level, give corresponding second level RS latch S end, and this signal is implemented to latch.After this remote controller DTMF decoding circuit is received the second order digit sign indicating number and decoding that main frame is dialed, pass to the decoding of four line binary decoding distributor circuits, corresponding numbering pin output high level is given the corresponding RS latch in the second level, this latch " Q " pin output low level is given digital coding appliance mains switch triode, saturated and the conducting of switch triode, the digital coding circuit on this road gets electric enforcement coding, and is delivered to the high frequency wireless transmitter module and sends digitally coded radio wave.The decoding circuit identical with this digital coding received signal, and its output pin sends high level and gives drive circuit, drives the actuating of relay.

Because in a single day a certain address of multiaddress multidata input numeral decoding circuit end is driven, it can not closed automatically, so the host machine part of remote controller needn't be charged always, after the calling party has dialed number on-hook, main frame also can on-hook, and in desire when shutdown, then only need make other addresses of one tunnel of this road decoding circuit be driven (this end output can be unsettled), then original a road can turn-offing of driving.The multidata coded system of multiaddress can up to ten thousand kinds, so needn't worry to interfere with each other.

This remote controller has fully phased out the electric wire that is connected between remote controller and the institute control equipment, install very simple, needn't backguy, simultaneously because simple to operate, can not produce misoperation and mutual interference mutually, can be used as the home intelligence commercial grades, with the intelligentized development of favourable promotion family and unit.
