Description
The utility model belongs to electronic equipments, specifically a kind of telephone remote control.
Existing on the market all kinds of telepilots are a lot, but with regard to its transmission mode, mainly are divided into wireless and wired two kinds.This telepilot of two types all has defective in various degree.For example, the telepilot of wireless mode can only be realized closely controlling, and then will be subjected to the restriction of aspects such as frequency, power, cost if realize far distance controlled.In recent years, though the telepilot that utilizes the telephone wire transmission that has occurred is to solve remote and power problem, but, owing to adopt the Single-chip Controlling telepilot, thereby complex structure, cost are very high, simultaneously owing to only provided the single channel remote control port, and do not have driving circuit, depositing simultaneously the deficiency of two aspects again: the one, bigger with the absorption of phone network coupling ringing-current, the 2nd, the passive inductance coupling dialogue web influence that is adopted is bigger.
The purpose of this utility model is to avoid the deficiency of above-mentioned prior art, provides a kind of circuit structure simple, and cost is low, and little with phone network coupling ringing-current, and impedance matching is to the little telephone remote control of phone network influence.
The technical scheme that realizes the utility model purpose is to be carrier with existing words line.By the words line control signal is sent to telepilot, according to control signal multichannel electric equipment carried out real-time switch remote control.This telepilot is mainly by rectification circuit, change-over circuit, ring detecting circuit, Ring-down count circuit, coding circuit, speech channel match circuit, and decoding circuit, decoding scheme, latch cicuit, control circuit and sound circuit constitute.Wherein ring detecting circuit adopts ringing-current to absorb little electric capacity every direct sum photoelectricity coupled circuit, and the Ring-down count circuit mainly adopts decimal system counting chip and double D trigger, hex inverter and peripheral cell to constitute.Coding circuit mainly adopts decimal system counting chip and four latchs, and four input nand gates and peripheral cell constitute, and the speech channel matching network adopts the active network circuit.Rectification circuit, change-over circuit, decoding circuit, decoding scheme, latch cicuit, control circuit, sound circuit adopt custom circuit, and the annexation of each circuit as shown in Figure 1.Be the input of the rectifier line output of answering, output connects the conversion circuit, and the output of change-over circuit is divided into two-way, and one the road inserts the speech channel coupling, and one the road inserts ring detecting circuit, and ring is examined then circuit and given the Ring-down count circuit with ringdown with the form of square wave.The Ring-down count circuit is divided into two-way output, one tunnel control transformation circuit and sound circuit, after ring five times, flow to control signal of change-over circuit, to talk about line and speech channel match circuit and connect, and trigger sound circuit simultaneously, another road output of Ring-down count circuit is connected to coding circuit, when resetting, its coding circuit is resetted simultaneously to coding circuit output control signal.Coding circuit is divided into three tunnel outputs, and one the road is connected to the Ring-down count device, and when mistake appearred in coding, for counting circuit provides reset signal, two-way was connected respectively to sound circuit and latch cicuit in addition, after coding is correct, triggered sound circuit, opened latch cicuit.The output of speech channel match circuit links to each other with decoding circuit.Decoding circuit output two paths of signals, one the tunnel connects decoding scheme carries out decimal system decoding to binary-coded decimal, one the tunnel be connected respectively to Ring-down count circuit and coding circuit, secondary double-audio signal dwell interval be provided for the Ring-down count circuit respectively, provide operational order to decoding scheme.Decoding scheme, latch cicuit, control circuit, sound circuit connect successively, and wherein another road output of control circuit is connected with electrical appliance, provides switching signal to electrical appliance.The output of sound circuit is connected to the speech channel match circuit, according to different trigger pips, produces different voice signals, transfers to the user by the speech channel match circuit.
Of the present utility model transmitting is telephone set or portable machine, and signal form is a touch-tone signal, during use, its ringing telephone stations signal of dialing is arranged to a constant, and ringing number counted, when the no show value of setting, disconnect the words line as receiver off-book, telepilot.And when ring reached the value of setting, telepilot then connect speaking wire automatically, and provided voice signal to the other side.Require the input password, one group of numerical value of four 0-9 that password is provided with voluntarily for the user, this numerical value can be finished by code switch, if the password of user's input is when being provided with password not match, telepilot meeting automatic hand-up.If behind the input password with password is set when identical, telepilot can provide voice signal, tells the user input instruction code again, order code is the agreement numeral: different digital is represented the Push And Release of Ge Lu consumer.The utility model is made as four tunnel controls, and 1,3,5,7 are respectively opening of one, two, three, four each roads; 2,4,6,8, be respectively the pass on one, two, three, four each roads.After having pulled out the telecommand sign indicating number, the user can pull out 9, and at this moment, telepilot is automatic hand-up then.The purpose that password is set is in order to prevent the remote control of non-user operation to consumer, and telepilot also is provided with and automatically resets the automatic hand-up function simultaneously.
The utlity model has following advantage:
1. the utility model is owing to transmit according to different signals on ring detecting circuit and speech channel match circuit structure and adopted different coupling scheme, promptly at first adopt height to force down appearance value electric capacity and cut off direct current ringdown, improve AC impedance, simultaneously ringdown is carried out rectifying and wave-filtering, and adopt photoelectricity to be coupled, thereby both reduced the ringing-current absorption, and improved detection sensitivity, preferably resolve isolating problem again.Simultaneously owing to adopted active network to carry out the dc impedance coupling, and with transformer coupled, thereby it is little to have a direct current resistance, and AC impedance is big, isolate reliably and frequency characteristic good.
2. the utility model has been owing to adopted digital circuit chip commonly used in Ring-down count circuit and coding circuit, thereby and big reduction cost of products, it is simple to operation that password setting has adopted plucking number sign switch to make, and improved reliability of products.
Be described in detail structural principle of the present utility model below in conjunction with accompanying drawing:
