Description

Automatic dial alarm

The utility model relates to the Remote Control Automatic dialing alarm device of a kind of infrared encoding and decoding.

Existing various warning device major part does not adopt coding-decoding circuit, wrong report easily, though some has coding and decoding device, coded number is few, and confidentiality is not strong.In addition, the existing telephone autoalarm does not all have the anti-ringdown observation circuit of employing, and therefore, alerted parties (as public security bureau " 110 " platform) can't further confirm alarm call and alarm content when needed.

It is many that the purpose of this utility model provides a kind of coded number, the automatic dialing alarm device of strong security, only need open hand-held remote controller simply, can make warning device enter the state of alert, the user stores alarm content and warning number as required in advance, in case alert occurs, this device can dial automatically and notify relevant department, and make relevant department finish the anti-operation of shaking, further confirm the alert content.

The utility model is deposited Power Generation Road, number display circuit, induction pick-up, anti-ringdown observation circuit by 8031 single-chip microcomputers and infrared encoding and decoding remote control circuit, speech IC, signal tone testing circuit, number and is finished the judgement of the processing of dislodging machine, busy tone, dialing tone, ring-back tone jointly, by telephone wire voice and warning number are sent, 8031 single-chip microcomputers directly connect infrared encoding and decoding remote control circuit, to increase the confidentiality of warning device, 8031 single-chip microcomputers directly connect with anti-ringdown observation circuit, and collaborative relevant department finishes anti-ring operation.

Further narrate below in conjunction with accompanying drawing:

As shown in Figure 1, the utility model is deposited Power Generation Road, number display circuit, infrared coding-decoding circuit, induction pick-up by 8031 single-chip microcomputers, language integrated circuit, signal tone testing circuit, anti-ringdown observation circuit, number and is formed the P of 8031 single-chip microcomputers _1.1, P _1.2, P _1.3On connect three relay switch K respectively ₁, K ₂, K ₃, the P of single-chip microcomputer _1.6Pin directly connects the P of single-chip microcomputer with infrared coding-decoding circuit _1.4Pin connects with anti-ringdown observation circuit.Under normal conditions, K switch ₁, K ₃All be to disconnect, subsets are work as usual, and when alert took place, induction pick-up was given 8031 single-chip microcomputers with high level signal, makes P by software programming _1.1, P _1.3Output Gao Ping, K ₁, K ₃Closure is simulated off-hook, and three kinds of signal tones such as dialing tone, ring-back tone are detected judgement, passes through K ₂The break-make telephone number that will store in advance send, judge simultaneously whether ring-back tone stops to send, if busy tone do not occur after stopping sending ring-back tone, then 8031 single-chip microcomputers start the language integrated circuit, the alarm call number and the alarm content of prior typing are sent, 8031 single-chip microcomputers are monitored tone playing state, are treated that tone playing state finishes, and discharges K simultaneously ₁, closed K ₃, this moment, 8031 single-chip microcomputers entered anti-ringdown monitoring state.If after the dialing, what send on the circuit is busy tone, or to stop sending behind the ring-back tone also be busy tone, and then 8031 single-chip microcomputers are simulated the dislodging machine once once more, and repeat said process, till connecting phone.

As shown in Figure 2, the anti-ringdown observation circuit of this device comprises C ₂₈, C ₂₉, D ₁₁, D ₁₂, R ₄₂, R ₄₃, R ₄₄, IC ₅, IC ₄Form IC ₅1.2 pin and C ₂₈, D ₁₁Series connection is with C ₂₉, D ₁₂Parallel connection, IC ₅5 pin and IC ₄Connect IC ₄P with 8031 single-chip microcomputers _1.4Connect.When 8031 single-chip microcomputers entered anti-ringdown monitoring state, have a ringing signal this moment, and (GB was 75

± 25 ) input, through C ₂₈, D ₁₁, C ₂₉, D ₁₂, R ₄₂, R ₄₃, R ₄₄After step-down, filtering, the voltage stabilizing, make IC ₁₅The 1.2 pin conductings of (photoelectrical coupler), and make its 5 pin become low level by high level, again through IC ₁₄Give 8031 single-chip microcomputers after anti-phase.After 8031 single-chip microcomputers detect this signal, start the language playback circuitry, with language send, etc. after playback finishes, get back to anti-ringdown monitoring state again, get ready for carrying out examining of alarm content once more.

As shown in Figure 2, number is deposited Power Generation Road mainly by keyboard, IC ₈, V ₅, V ₆, V ₇, S ₃, S ₄Form IC ₃10 pin connect reset key S ₃, 11 pin and V ₅, V ₆Connection, 12 pin and V ₇Connect 13 pin and selector switch S ₄Connect.Work as K _1-1, K _1-2After the closure, 8031 single-chip microcomputers pass through K _2-1To simulate the redial key break-make once, the telephone number that is about to storage in advance sends.IC ₈Be the signaling integrated circuit of pulse/audio frequency compatibility, can redial 32 item sign indicating numbers, have the last number of storage and mix multiple functions such as redialing the last number automatically, in the time of need revising as number storing, as long as by a reset key S ₃, just new number can be re-entered, when code sending method is pulse, 11 pin will be exported a string negative pulse, make V ₆, V ₅Continuous mutually conducting and ending, make the current return in the telephone line produce interrupted, formed DC pulse, 12 pin are double frequency multitone input pin, and when code sending method was audio frequency, this pin was a high level, produce suitable low class frequency and high class frequency in the sheet this moment, mix the back and export frequently for double-tone, 13 pin are that code sending method is selected pin, with selector switch S ₄Connect, in order to cooperate the collect the digits needs of interface of difference.

As shown in Figure 3, in order to strengthen the confidentiality of warning device, this device spy has set up infrared coding-decoding circuit, and it is made up of infrared coding radiating circuit (a) and infrared decoding receiving circuit (b), in the infrared coding radiating circuit, and the ED5026 ic chip of encoding ₁₇The 1-13 pin for the coding pin, external miniature code switch, it is encoded to 4 ¹¹Individual, more than 400 ten thousand capable of being combined, R ₃₃Be built-in oscillator outer meeting resistance, S ₁For sending button, when pressing S ₁The time, by IC ₁₇17 pin send the coded address, via IC ₁₃, R ₃₉, C ₂₆After the modulating oscillator modulation of forming, through R ₄₀Give V ₁₀Amplify, and by infrared transmitting tube VD ₂Launch, in infrared decoding receiving circuit, as infrared receiving tube VD ₁After receiving infrared encoded signal, through IC ₁₅(CX20106A) put in advance,, and pass through V by the output of 7 pin ₃After the amplification, coded signal is sent into IC ₁₆14 pin, IC ₁₆Be ED5028 decoding integrated package, the 1-13 pin is the local coder pin, external miniature code switch, R ₃₆Be built-in oscillator outer meeting resistance.Coded number is 4 ¹¹Individual, receive coded signal after, through four times continuously relatively,, decode so successfully, from IC if identical with local coder ₁₆Positive pulse of 17 pin output, this pulse signal footpath R ₃₅Make V ₉Conducting, and through phase inverter F ₆(IC ₄) send into 8031 Single Chip Microcomputer (SCM) system after anti-phase, 8031 Single Chip Microcomputer (SCM) system are done " 1 " with this signal note after receiving this high level signal, and with signal last time relatively, if be " 0 " last time, then 8031 systems enter the vigilance task state, if last time signal was " 1 ", then 8031 Single Chip Microcomputer (SCM) system withdraw from the vigilance task state, zero clearing is simultaneously prepared for entering the state of alert next time.

The utility model can be widely used in business unit and families such as finance, warehouse, factories and miness, assembles different induction pick-ups, can prevent fires the automatic dialing alarm of burst things such as gas defence, antitheft, medical first aid.
