Description

Mobile phone control sell telegraph circuit automatically

(1) technical field: the utility model relates to electronics, be the control of a kind of mobile phone sell telegraph circuit automatically.

(2) background technology: honor box generally adopts coin to connect the coin device both at home and abroad at present, receive client's coin and sell newspaper automatically, this will ask for help carry coin, the newspaper price differs, price is the newspaper of four jiaos, angle, land and one yuan two jiaos, then requires people to carry the different coin of multiple face amount, perhaps requires honor box to have the small change function, these phenomenons have greatly limited honor box and have promoted the use of.

(3) summary of the invention: what the purpose of this utility model provided the control of a kind of mobile phone sells telegraph circuit automatically, it is contained on the honor box, honor box is equipped with pair of telephone lines, and applied for a telephone number in telecommunication bureau, when client dials telephone number on this honor box with local mobile phone, just send a newspaper in the honor box and take away for client, both accurately and reliably, convenient and easy again.

The technical solution of the utility model is: the telegraph circuit of selling automatically of mobile phone control is configured on the honor box, its input connects with the telephone wire of honor box, output leads to honor box actuator, it is characterized in that: the information on the telephone wire is led to honor box actuator through polar protective circuit, FSK decoding circuit or DTMF decoding circuit, single chip circuit; Also be parallel with telephone line states testing circuit, extension/off-hook control circuit and DTMF generator between telephone wire and the single chip circuit; Between polar protective circuit and single chip circuit, series connection is provided with adapter circuit and sound circuit; Be provided with single-chip microcomputer and connect the data storage of record honor box feedback information.

In the use, when the client dialed the circuit number of this honor box, the single-chip microcomputer of selling automatically in the telegraph circuit decoded incoming information from telephone wire, comprised calling subscriber's contents such as telephone number, time.After single-chip microcomputer obtains the telephone number of caller, carry out self-filtering, long-distance for moving, fixedly expect someone's call, will not respond.Because the calling subscriber of toll telephone, its communication rate are paid the fees in the other places, newspaper fee difficulty.The general calling subscriber of landline telephone can not take newspaper then and there away away from honor box.And to mobile phone handsets rear side phone number in this area, single-chip microcomputer responds, automatic off-hook, and the while playout length is that 3 seconds prompt tone is given the calling subscriber.After prompt tone finished, automatic hand-up also provided the operation enabling signal to the actuator of honor box, and actuator provides a newspaper to the client.In the process of playing alert tones, single-chip microcomputer is monitored the off-hook hook state of telephone line simultaneously, if the client does not hear out the prompt tone on-hook, single-chip microcomputer does not provide enabling signal to the actuator of honor box, because the air time is too short, might influence the air time record of SPC telephone exchange, cause the rate mistake.The owner of honor box can entrust telecommunication bureau, according to mobile phone user's record of the telephone number of having dialed honor box, withholds the newspaper expense.

The utility model is compared with existing Slot Machine of Newspaper, have easy to use, beneficial effect accurately and reliably charges.

(4) description of drawings: Fig. 1 is a circuit theory schematic diagram of the present utility model; Fig. 2 is the embodiment line map of polarity protection phone and decoding circuit; Fig. 3 is the embodiment line map of single chip circuit; Fig. 4 is the embodiment line map of sound circuit and adapter circuit, and Fig. 5 is a telephone line states testing circuit embodiment line map.

Among the figure, 1-FSK decoding circuit, 2-DTMF decoding circuit, 3-single chip circuit; the 4-adapter circuit, 5-telephone line states testing circuit, 6-sound circuit, 7-honor box actuator; the 8-data storage, 9-DTMF generator, 10-extension/off-hook control circuit, 11-polar protective circuit.

(5) embodiment: referring to accompanying drawing, the utility model contains following module in force, is described as follows: FSK decoding circuit [1], finish the decoding of the FSK standard caller data of sending here by telephone wire, and adopt the EM92547FSK decoding chip; DTMF decoding circuit [2] is finished the decoding of the DTMF standard caller data that sends by telephone wire, adopts the HM9270DTMF decoding chip; Single chip circuit [3] adopts the singlechip chip of 8031 kernels, as 8031 chips of INTEL Corp.; Adapter circuit [4] realizes that the differential output of sound circuit is converted into single-ended output over the ground, adopts the LM386 chip; Telephone line states testing circuit [5], busy/not busy sound that the identification stored-program control exchange sends to telephone line, stored-program control exchange provides interrupted 450HZ audio signal, interrupted length at interval, busy/not busy state of just having represented circuit, adopt audio decoder chip LM567 and single-chip microcomputer to cooperate and to discern telephone line states; Sound circuit [6] is realized sending the connection prompt tone to the calling subscriber behind the phone off-hook, and this circuit is the typing suggestion voice, plays under the control of single-chip microcomputer, adopts the ISD1110 chip; Data storage [8] writes down the mobile phone of effectively dialling in every day and buys the count off certificate, adopts I ²The E of C bus ²PROM AT24C02 chip; DTMF generator [9] is realized the DTMF pulsing function of honor box, finishes the business datum exchange with administrative department, adopts the HT9200B chip; Extension/off-hook control circuit [10] under the control of single-chip microcomputer, drives small low-voltage direct current mechanical contact relay, opening circuit and closure of relay contact, imitation realizes the off-hook and the on-hook of phone, and relay adopts DC 5V operating voltage, 2 groups of contacts, contact capacity are DC 24V, 1A; Polar protective circuit [11] prevents to be the bridge circuit of being made up of 4 IN4001 diodes because of external call polarity reversal output defective chip.

Narrate the utility model embodiment circuit operation now, when mobile phone is dialed the telephone number of honor box, calling subscriber's telephone number information, by telephone wire and polar protective circuit [11], together import with ringing signal, if ESK standard incoming telephone signal, then export through ESK decoding circuit [1], if DTMF standard incoming telephone signal, then through DTMF decoding circuit [2] output, after single-chip microcomputer [3] received incoming information, software carried out telephone number and filters, mobile phone incoming call to landline telephone and other regions will not respond; To the mobile phone incoming call of this area, Single-chip Controlling extension/circuit for answering [10] off-hook is controlled sound circuit [6] simultaneously by adapter [4] playing alert tones.In the time of playing alert tones, the timer of single-chip microcomputer inside starts, by telephone line states testing circuit [5] to single-chip microcomputer feedback line state information.If in 3 second time period of playing alert tones, the calling subscriber shifts to an earlier date on-hook, then is considered as client and sells newspaper and call out incorrectly, and single place machine is not exported and sold the newspaper enabling signal; If after prompt tone finishes, calling subscriber's on-hook then is considered as selling newspaper and calls out correctly, and single-chip microcomputer sends to honor box actuator [7] and sells newspaper start-up control signal, gives the client with a newspaper.After this, the reset circuit work that links to each other with single-chip microcomputer, entire circuit is got back to and is sold newspaper preceding state.The valid telephone signal that mobile phone is dialed deposits in data storage [8], Single-chip Controlling DTMF generator [9], and the DTMF pulsing function of realization honor box is finished the business datum exchange with administrative department.
