Abstract

The utility model relates to an air conditioner telephone remote controller with a speech prompting function, which belongs to controllers for air conditioners. The utility model is characterized in that a singlechip U1 can receive double-tone multifrequency codes such as user pass words, control codes and telephone numbers which are come from an external line inserting piece through a double-tone multifrequency decoding circuit, a coupling coil and a talking circuit orderly; after the double-tone multifrequency codes are treated by the singlechip, double-tone multifrequency signals for executing operating and controlling programs are sent to users through a talk speech outputting circuit, the coupling coil and the talking circuit, and the operation of an air condition is controlled by an infrared sending circuit according to operating codes sent by users. Because signals are received and sent through different passages, the reliability of the utility model is largely increased. The utility model also has the speech prompting function which makes users not remember a large number of codes. The utility model has convenient operation.

Description

Air conditioner telephone remote control with voice prompts

The utility model relates to a kind of air conditioner telephone remote control with voice prompts.

Number of patent application is 97201852.2, the applying date is 1997.3.19, name is called: the utility model patent of " air conditioner telephone controller " has proposed a kind of employing dual tone receiver and has been connected with public telephone network, the air conditioner telephone controller that the user can carry out open and close, heats, freezes and dehumidify control by dual tone phone to the air-conditioning in the family anywhere, it is applicable to the remote telephone of various air conditioners.Its shortcoming is: with the part of telephony interface, same circuit path has been adopted in the reception of signal and transmission, in case the time interval of the signal of bringing from phone line is too short, misconnection will takes place receive, its probability is about one thousandth to thousand/two, poor stability; The user need remember a large amount of codes simultaneously, uses inconvenience.

It is a kind of highly reliable, easy to use and have an air conditioner telephone remote control of sound prompt function that the purpose of this utility model is to provide.

Of the present utility model being characterised in that: it contains 89 series monolithic U1, deposit, get the user cipher locking memory U2 that is subjected to single-chip microcomputer U1 control, what its input was subjected to single-chip microcomputer U1 control serves as main plucking/the on-hook control circuit of constituting with relay R LY1, the speaking circuit U5 that its input links to each other with telephone set outside line plug-in unit J2 output behind the control contact of relay R LY1, input links to each other with the output of speaking circuit U5 behind acoustic transformer T1 and dual-tone multifrequency decoding circuit U4 that the dual-tone multifrequency sign indicating number input of output and single-chip microcomputer U1 links to each other, input links to each other with the speech output code output of single-chip microcomputer U5 and voice signal output circuit U3 that output links to each other through the voice signal input of acoustic transformer T2 and speaking circuit U5, the link to each other bell flowing detecting circuit of machine transplanting of rice part J3 output of the ringing-current detection signal input of output and monolithic U5 and input is answered the call, have scene/far-end setting state switch SW 1 that MTS and its scene/remote state signal output part link to each other with the status signal test side of single-chip microcomputer U5, air conditioner infrared control circuit and power supply.

Use proof: it has reached intended purposes.

In order in conjunction with the embodiments the utility model to be described in detail below, show as follows employed accompanying drawing number of present specification and title brief introduction:

Embodiment:

In Fig. 2, the sheet choosing end CS of user cipher locking memory U2, clock end SK, data terminal DI, DO links to each other with the corresponding controling end P1.3-P1.0 of single-chip microcomputer U1 respectively successively, voice signal output circuit U3 adopts chips W 55F10, its input TG1, TG2, the BVSY end links to each other with the voice signal sign indicating number output P1.4-P1.6 of single-chip microcomputer U1 respectively successively, the control signal input of air conditioner infrared control circuit links to each other with the infrared driving signal output part of the air conditioner of single-chip microcomputer U1 P1.7, pluck/the control signal input of on-hook control circuit links to each other with the P0.0 of single-chip microcomputer U1, the output of bell flowing detecting circuit U6 links to each other with the ring ringing-current detection signal input P0.1 of single-chip microcomputer U1, the remote state of scene/remote state configuration switch SW1, three output REMO DET of presence states and password state, LOCA DET, CODE DET links to each other with the P2.0-P2.2 of single-chip microcomputer U1 respectively successively, the dual-tone multifrequency sign indicating number output DTMFD1 of dual-tone multifrequency decoding circuit U4, DTMFD2, DTMFD4, DTMFD8, DTMFDV links to each other with P2.3～P2.7 of single-chip microcomputer U1 respectively.In air conditioner infrared control circuit, its input TR DRW links to each other with the air conditioner infrared control signal output P1.7 of single-chip microcomputer U1, the input LED4 CONT of presence states infrarede emitting diode display circuit links to each other with the corresponding output end of unit sheet U1.The movable contact 5 of relay R LY1 links to each other with the input INR of speaking circuit U5 behind the diode limit circuit, and fixed contact 10 links to each other with the output 2 of plug-in unit J2,2 ends of plug-in unit J3 simultaneously.The

output

8,7 of voice signal output circuit U3 links to each other with the

input

7,6 of speaking circuit U5 through acoustic transformer T2, and voice signal is transported to telephone set plug-in unit J3 from 1 pin of speaking circuit U5.Touch-tone signal is sent to the double-tone input pin 7 of decoding circuit U4 frequently from

4,5 outputs of speaking circuit U5 through acoustic transformer T1.The movable contact 2 of scene/remote state locking switch SW1 links to each other with fixed contact 1, then is in remote state, links to each other with fixed

contact

3,4, then is in presence states.

When ring, single-chip microcomputer U1 is just by bell flowing detecting circuit U6 counting, after 6, single-chip microcomputer U1 just drives relay R LY1 off-hook and gives connection to external call, signal in the outside line is just transported to single-chip microcomputer U1 again through the 7th pin that plug-in unit J2, relay R LY1, speaking circuit U5, acoustic transformer T1 are coupled to dual-tone multifrequency decoding circuit U4 after converting the voice signal sign indicating number to after the voice signal circuit U 3.If presence states user is provided with password, single-chip microcomputer U1 just deposits user cipher among the latch U2 in; If just the verification of setting among it and the latch U2 of carrying out, verification is correct, just sends prompt tone by speech signal output circuit U3 for check and correction user cipher, single-chip microcomputer.Otherwise the prompt cipher input is wrong, once more input.If control code, then single-chip microcomputer U1 drives infrared transmitting tube LED1, LED2 emission control sign indicating number control air-conditioner by P1.7.

This shows that the reception of its touch-tone signal has been used different passages with transmission, thereby improved the reliability of control.Simultaneously, it has sound prompt function again, makes the user needn't remember a large amount of codes, uses more convenient.
