Abstract

The utility model relates to an automatic digital signal warning telephone of two audios increases the sensor interface in the telephone that has two audios dialing and memory number function, automatic code logic control circuit and busy tone detection circuitry of sending out are equipped with the trigger in the logic control circuit to control off-hook and storage key dial-out. At ordinary times, the telephone is still used as ordinary telephone, and when it is used for alarming, it can automatically dial out BP telephone number, monitor number, alarm user number and appointed code, and utilizes local telephone network, specially '127' station to implement digital signal alarm.

Description

Automatic digital signal alarm telephone
The utility model relates to a kind of automatic digital signal alarm telephone set, belongs to telephone communication warning system technical field.
The telephone automatic alarm technology is summarized following two kinds, a kind of employing audio alert, the another kind of password figure signal alarm that adopts.First type of enforcement is simpler, does not need complicated surveillance, but is difficult to realize automatic supervision.Second type of need obtains special-purpose central alarm surveillance support, and it is big to implement difficulty, has not yet to see ripe report.Disclosed digital alarm call in the Chinese patent 90205346.9, though adopted numerical ciphers storage and signaling scheme, but the code memory effect commonly used in the integrated telephone set that this scheme is in fact only widely used quite at present, need also do not possess automatic warning effect with the button triggering, its another shortcoming is only to use as special alarm.
The purpose of this utility model is to disclose a kind of the supervision reporting to the police to support to require low digital signal automatically alarming telephone set, can utilize existing telephone machine and local network to realize the digital signal warning more conveniently.
Task of the present utility model is achieved in that to have on dual-tone dialing and a plurality of Number Storing Key telephone set at one and adds sensor interface, logic control circuit and busy call tone signal testing circuit, described logic control circuit is by trigger and automatic off-hook, number storage transfers to the key control circuit to form, described sensor interface is connected with the CLK end of trigger, described off-hook, transfer to the key control circuit to be connected with the trigger output, at above-mentioned off-hook, transfer in the key control circuit and respectively be provided with the RC delay circuit, described busy call tone signal testing circuit is provided with the 450HZ phase-locked loop circuit, its signal input part is through amplitude limit, amplifying circuit is connected with local line, its logic output terminal is delivered to the reset terminal of described trigger with signal one road, and trigger CLK end is delivered on another road.
For adapting to " 127 " platform communication mode, described number storage transfers to the key control circuit to be provided with two-way, have different RC delay parameters, to transfer to two groups of digital signals by the priority order, first group is " the dynamo-electric words of 127+BP number ", second group is warning message, i.e. " alerts user telephone number+agreement code " obtains the second group alarm message digit again after can making beeper be exhaled connection so automatically.
For adapting to the dedicated monitor communication mode, also can increase a trigger, its CLK end signal is taken from above-mentioned second group and is transferred to the key control signal, its output one tunnel connects the automatic off-hook control circuit, another road connects another number storage and transfers to the key control circuit, can send " ringing number+warning number+code " totally 16 bit digital to monitor.
Described sensor interface can be suitable for effectively signal source of any high level (5V).
Use this automatically alarming telephone set, only need to transfer to the dual tone phone machine of key function to increase a small amount of annex with the band number storing to existing, do not influencing under original communication function prerequisite, the realization high-speed figure is reported to the police, this type of alarm can directly utilize " 127 " platform communication mode, is receiver with the beeper, also can use dedicated monitor, set up automatic alarm monitoring system, this is a kind of small investment and the high telephone call technology of reliability.
Below in conjunction with drawings and Examples, the utility model is specified.
Fig. 1 is the automatically alarming telephone set circuit theory diagrams.
Fig. 2 is infrared alarm transducer receiving unit circuit theory diagrams.
Fig. 3 is an infrared emission partial circuit schematic diagram.
Among Fig. 1 sensor interface CP through or door and trigger M1:B(4013) CLK hold and to be connected, the Q end output signal of this trigger is divided into three the tunnel after R12, C11 time-delay, one way control switch pipe G2, automatic off-hook relay J adhesive (being off-hook) the two tunnel is delayed time through R13, C12 respectively in addition, R17, C16 time-delay, control two electronic switch M6:A and M6:B(4066), M6:A and M6:B make two preset number storages transfer to key K1, K2 successively to connect, first transfers to key to send the beeper number to " 127 " platform, and second transfers to key to send the warning message numeral.Also be provided with the second trigger M1:A(4013 among this figure), its CLK end signal is taken from above-mentioned second and is transferred to key K2 control signal, its output Q still controls G2 after R11, C9 time-delay, another output Q is then through the 3rd group of electronic switch M6:C(4066 that transfers to key K3 of R18, C10 time-delay control), this dial-out key can directly be sent call number and warning message numeral to monitor.Above-mentioned second control signal of transfering to key K2 is simultaneously also as the reset signal of the reset terminal R of the first trigger M1:B.
Local line TEL IN imports amplifier G1 into through the switch JK of relay J, amplitude limiter D1, D2 and demodulator M2(LM567), M2 is as the phase-locked loop circuit of busy tone 450HZ, " 3 " end is input, " 8 " end is logic output, low level is effective, handle through gate circuit, with sensor interface CP abreast through or door add to the CLK end of trigger M1:B, also add to the reset terminal of two trigger M1:B and M1:A simultaneously through gate circuit, during work if meet busy tone, " 8 " end of M2 resets M1:A for low level after anti-phase processing, (this moment, M1:B resetted), M1:B is triggered, repeat above-mentioned automatic off-hook signaling process again.
Also be provided with a manual reset circuit that comprises button K in this circuit, reset signal is delivered to two trigger reset end R1, R2 through gate circuit.Be communicated with button K, can make trigger forced resetting within the delay time of output control circuit, avoid false alarm.
Fig. 2 and Fig. 3 provide an infrared alarm sensor circuit example.NAND gate M11:A and M11:B(4093 among the figure) constitute the 430HZ oscillating circuit, M11:C and M11:D constitute the 40KHZ oscillating circuit, and 40KHZ is that the 430HZ modulation is after amplifier G11, G12 amplification is sent signal by infraluminescence pipe D11, D12.Photosensitive tube D13, D14 received signal are after the infrared discharge road M12(CX20106 that gives) handle, deliver to phase-locked loop M13(NE567 at " 7 " pin output 430HZ signal) " 3 " end, bring out existing low level in " 8 ", input telephone set sensor interface (CP) after the shaping.If when having object to block between transmitting tube D11, D12 and photosensitive tube D13, the D14, " 8 " end of M13 is high level, thereby obtains alarm signal output.A kind of warning sensing scheme is only proposed here.As long as make telephone set sensor interface CP obtain an effectively input (high level), any method all can.
