Description

Multifunction computer speech-sounds automatic siren

The utility model belongs to a kind of electronic alarm, is used in particular for the electronic warning of telephone set.

At present, existing various electronic alarm, its type of alarm often is confined to the sound and light alarm in the scene (Control Room), and can not correctly discern the warning that the monitoring circuit disconnection fault causes, the telephone set that is partly with warning function then need manually be intervened, and can not finish whole alarm procedure automatically.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, thereby a kind of sound and light alarm at the scene is provided, again the autoalarm that can implement to report to the police to distant place user by phone.

The purpose of this utility model realizes in the following way:

See Fig. 2, Fig. 3: this alarm is made up of power supply/monitor board and motherboard, wherein: power circuit is by chip 78L05,7805,7812, QZ forms, in addition, IC11, IC13, the K composition manually starts circuit, the sensing start-up circuit is by IC17, IZ15 and sensor are formed, J1-1 on the motherboard, J1-2, B, BG1, BG2, IC6 constitutes interface network, A1 and LM567 form the outside line input, decoding scheme, three kinds of signals on the telephone wire: hum, busy tone and ring-back tone arrive LM567 phaselocked loop tone decoder after A1 amplifies, the 3 pin frequency input signals of LM567 are in its passband, 8 pin output low levels then are through arriving 8031 P3.4 mouth after two not gate shapings; The DTMF pulsing circuit that A2, A3, LPF1, LPF2, A5 form, become triangular wave by P1.1 mouth outputting dual tone multi-frequency high group square-wave signal integration behind the A2 integrator, the pure sine wave signal of exporting after low-pass filter XL-1 filtering higher hamonic wave is delivered to totalizer A5; The low group square-wave signal of dual-tone multifrequency is through A3 integration, XL-1 filtering higher hamonic wave, and also the sine wave output signal is to A5, and high low group signal is delivered to B after totalizer A5 addition, amplification, and is coupled to outside line through B; LPF2, A4, BG3, RC forms alarm voice and forms circuit, the datagram poster tone signal that P1.4 by 8031 sends is through the RC integration, A4 isolates the voice signal that the back forms, be higher than 3000HZ and the signal that is lower than 300HZ through the LPF2 filtering, formation is near the signal of original speech, through A5, B delivers to outside line, pulse signal circuit is by IC5, IC6, BG1, BG2 forms, the pulse dialing signal of being sent by P3.1 drives through IC5, IC6 isolates, control BG1, the on-off of BG2, control circuit is by IC5, J forms, when P3.2 sends high level, the J adhesive, outside line and this machine are connected, when P3.2 sends low level, outside line and this machine disconnect, IC9, IC2, IC8, LM386 forms sound light alarming circuit.

In the sound light alarming circuit, when monitoring circuit generation disconnection fault, implement break alarm, the P3.3 of the CPU of 8031CPU sends high level at this moment, forbid IC82 work, and make IC9 4 pairs of P1.3 gatings, and the police whistle sound of " too pout " that produced by software is exported by P3.0, send the loudspeaker sounding after the LM386 power amplification, the frequency of being sent by P1.3 is that the door 4 of flashing signal by IC9 of 2HZ goes the driving LED flicker, implements Normal Alarm when alert condition takes place, at this moment, sound and light signal produces by external circuit, and P3.3 sends low level, makes IC8 get electric work, after amplifying, LM386 send the loudspeaker sounding by the alerting signal that IC8 produces, P1.3 sends high level and makes

IC9 door

3,4 pairs by IC9 door 1,2 frequencies of forming are the flashing signal gating of 4HZ, thereby make LED send the flashing signal that frequency is 4HZ, finish sound and light alarm.

The utility model is compared with existing various electronic alarms has following advantage:

1. by microcomputerized control, stable and reliable for performance, the wrong report rate of failing to report is low.

2. in the time of can (Control Room) carries out sound and light alarm at the scene, can implement audio alert to distant place telephone subscriber again, call and need not manual intervention, all under the control of microprocessor, finish automatically.

3. the warning that causes in the time of discerning the warning that causes by the monitoring circuit broken string automatically and police's condition really takes place.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model theory diagram

Fig. 2 is the circuit diagram of power supply/monitor board

Fig. 3 is the motherboard circuit diagram

Fig. 4, Fig. 5 are level output state figure

In Fig. 3: 8031 is the single-chip microcomputer in a slice MCS-51 series, and wherein: P1.0 selects for the P/T dial mode; P1.1 is that dual-tone multifrequency high group signal goes out; P1.2 is that dual-tone multifrequency low group signal goes out; P1.3 is the control of break alarm light flash; P1.4 is that digital warning voice signal goes out; P1.6 differentiates for broken string/warning; P1.7 is that control is walked/stopped to clock; Chimes of doom output when P3.0 is broken string; P3.1 is that dial impulse goes out; P3.2 is the control of relay J 1 on/off; P3.3 is that siren is connected control when reporting to the police; P3.4 goes into for the line signal after decoding.

In Fig. 1, the principle of work of alarm is: when the monitoring circuit generation disconnection fault of " manually starting circuit " or " sensor start-up circuit ", this machine is implemented " break alarm ", at this moment, the start-up circuit that disconnection fault takes place can produce a control signal deactivation " mainboard power supply control circuit " automatically, connect the working power of motherboard, simultaneously, " break alarm/police's condition warning judging circuit " will be differentiated for " break alarm " automatically and send a low level to motherboard according to the signal level of monitoring circuit, motherboard turns to execution " break alarm " subroutine after being activated and receiving this low level signal, at this moment, the frequency that is produced by software is that the voice signal of 0.5S:0.5S and flashing signal that frequency is 1HZ are delivered to " sound light alarming circuit " for the 500HZ break-make ratio, after this drives, send acousto-optic, realize " break alarm ", this moment, main frame was only implemented sound and light alarm at the scene, and not to the making call telephone call in a distant place.

When warning region when a situation arises, this machine is implemented " alert condition is reported to the police ", and at this moment, two kinds of Starting mode are arranged: a kind of is to manually start, by manually starting the starting switch that is arranged on the monitoring circuit; Another kind is that sensor starts, be arranged at the probe on the monitoring circuit, after receiving the signal that alert condition takes place, automatically send alerting signal to " sensor start-up circuit ", these two kinds of Starting mode all can be produced a control signal deactivation " mainboard power supply control circuit " by start-up circuit separately, connect the motherboard working power, simultaneously, " break alarm/police's condition warning judging circuit " will be differentiated automatically according to the signal level state of monitoring circuit is " alert condition is reported to the police ", and send a high level to motherboard, motherboard is activated, and turn to execution " alert condition is reported to the police " subroutine after receiving this high level signal, after this, motherboard starts the acousto-optic circuit work of " alert condition is reported to the police " earlier, produce strong police whistle sound and light, sending a control signal then makes clock stop to walk about by " clock control circuit ", with the record warning moment of this moment, at last, motherboard is simulated the whole process of manually making a phone call of finishing under the control of software, after getting through, phone automatically the numeral warning speech of internal memory is delivered to outside line by " the warning speech forms circuit ", make the called subscriber can in time grasp alert condition, the digital alarm playback of telephone number that main frame is dialed and transmission all is pre-stored in the EPROM of 8031 systems.
