Description

Mobile phone digital remote control platform

The utility model belongs to the wireless remote control technology field.

Wireless remote control technology obtains significant progress in recent years, people's daily life, and Industry Control, agricultural production every field telecontrol engineering product arises at the historic moment, and flowers blooming like a piece of brocade.Particularly the universal problem that must control the electrical equipment that has nothing in common with each other with a plurality of remote controllers respectively that produced of household electrical appliance is deposited the trouble of carrying and remembering if the indiscriminate reverse side of the too much mistake of remote controller that uses brings.In addition, the practical function of varied remote controller distance is generally all very limited on the market, does not accomplish to carry out on any time any distance remote control.

The purpose of this utility model provides a kind of mobile phone digital remote control platform, and the digital button that it need only be pressed on the mobile phone just can be any apart from a plurality of different remote-control targets of remote control.Moreover, need not set up between all controlled objects and the controlling platform lead therefore install and use very convenient.

The utility model is to realize like this, consult shown in accompanying drawing one, the accompanying drawing two:

The utility model is made up of cell phone (1), main frame (2), handset parts such as (8), it is characterized in that also spatially separating between separation, main frame (2) and the handset (8) on the space between cell phone (1) and the main frame (2); Main frame (2) is connected by lead (5) with telephone set (6), main frame (2) is connected with transformer L1 and L2 with fixing mobile phone (4), handset (8) is identical by a plurality of structures but encode handset group different and become, and each independent handset uses control line (10) to be connected with electromagnetically operated valve (11), electric control lock (12), television set electrical equipment such as (13) respectively.

Consult operation principle of the present utility model such as following shown in accompanying drawing two, the accompanying drawing three:

Accompanying drawing two is electrical schematic diagrams of main frame (2).Fixedly on the mainboard of mobile phone (4) the 1, the 2nd, two outputs of ringing circuit, the 3, the 4th, the output of head circuit inserts respectively in the circuit of main frame (2) by transformer L1 and L2.A, B are the communication telephones lines of introducing from telephone set (6).

The GSM mobile handset dialing all be adopt double-tone dialing frequently mode, therefore when cell phone (1) to telephone set (6) or fixedly (the two can choose one wantonly when reality is used) during mobile phone (4) dialing, its double-tone that sends frequency pulse meeting is sent to 1,2 two ends of A, B two ends or cell phone mainboard by communication network.

Accompanying drawing two is made up of circuit such as bell flowing detecting circuit, simulation off-hook, double-audio signal reception, decoding, coding, wireless transmission.Wherein 4N25 is that photoelectrical coupler, IC2YN9012 are that double-audio signal receiver IC3CD4514 is that 8421 code decoders, IC4UM3758-108A are that coded transmitter IC1NE555 is a delayer.

The ringing signal that A, B two ends send makes the BG1 conducting trigger the IC1 upset through electric coupling 4N25,3 pin output high potential.So the ring-back tone that BG3, BG5 conducting phone are in simulation off hook state, cell phone (1) earphone disappears.Press this moment arbitrary numerical key on mobile phone (1) keyboard just have the corresponding frequencies double-audio signal transfer out, through the input that C6, R11 deliver to IC2, after inter-process, send 8421 yards into IC3 decoding from its 11-14 pin.IC3 is a 4-16 line decoder, it will with 8421 yards corresponding output pins on export high potential.This high potential is sent into the corresponding encoded input of IC4 again, goes modulation transmitter wire antenna (3) to aerial emission high frequency radio wave so the 23 pin outputs of UM3758-108A are exported corresponding pulsewidth coding signal pulse.IC1 overturns after one section time-delay, and 3 pin return electronegative potential BG3 and BG5 is hung up by phone.

Accompanying drawing three is the electrical schematic diagram of handset (8).IC1 senses high-frequency signal after receiving circuit amplifies, IC1 is sent in detection owing to be transceiver monolithic encoding and decoding IC when reception antenna (9), and the input coding pulse can realize 256 kinds of action controls from 11-18 pin output multi-way control signals.Be the encoding state when on cell phone keyboard, pressing O in the diagram, then 9031 conductings of the 11st pin of IC1 output high potential, relay Q adhesive, normally opened contact Q1 closure, with 2 electrical equipment that connect of A, B through control line (10) energising work.During other figure key, the respective foot among the figure two in the 1-10 pin of IC4 is accepted high potential signal on pressing mobile phone (1) keyboard, and then the handset that IC1 is connected the high potential respective foot in advance among the figure three will make relay Q adhesive by output drive signal.We have just realized the digital code keyboard of use mobile phone (1) carries out remote control to a plurality of targets on any distance purpose like this.Power line (14) is the external power supply of handset (8).

If fixedly mobile phone (4) 1,2 ends have bell signal to export then L1 level can to produce corresponding pulses and make BG2 conducting, relay J suction make the listening key (OK key) of J1 normally opened contact closure, mobile phone (4) so the connection of closure mobile phone (4) off-hook.To export from 3,4 terminals, send from the figure key double-audio signal that cell phone (1) sends from L2 level of transformer.This signal through C4, R11 send into IC2 input, after control procedure with above-mentioned, do not give unnecessary details now.

When being used for main frame reception remote signal, relay P connects the usefulness that electric bell sends signal by its contact point.

Claims (1)

1, the utility model relates to a kind of mobile phone digital remote control platform and is made up of cell phone (1), main frame (2), handset parts such as (8), it is characterized in that cell phone (1) and main frame (2) spatially separate settings, main frame (2) and also separation setting spatially of handset (8); Main frame (2) is connected, is connected with lead (5) with telephone set (6) with transformer with fixing mobile phone (4); Handset (8) is identical by structure but handset group that encode different becomes, each independent handset is connected with electromagnetically operated valve (11), electric control lock (12), television set electrical equipment such as (13) respectively with control line (10).
