Abstract

The utility model relates to a high-intelligent communication monitor. A trigger switch circuit composed of controllable silicon is connected with a telephone trunk line, and the circuit after being connected with the telephone does not influence on incoming calls from external lines. When people except the host do not know the triggering form or the cipher and can not call an external line, when the trunk line is connected with other telephones for calls through illegal means, when line fault occurs, and when the telephone of the host is stolen, an alarm rings. The circuit can prevent calls through illegal means, save telephone charges, monitor communication instruments and monitor trunk lines. The utility model is suitable for wide use for telephones in government offices, enterprises and public institutions and personal homes, for fax machines, for computers, etc.

Description

The high intelligent communication watch-dog of specification

The utility model relates to wired communications field, is specially adapted to the monitoring of telephone line and phone.

Present domestic wire communication line and telephone set are because of no effective monitoring function, and stolen situation is comparatively serious, does not abroad also well address this problem.

Task of the present utility model is: a kind of high intelligence of concept, full-automatic communication watch-dog.Communication line and phone are carried out effectively monitoring, reach the anti-purpose of usurping of phone and circuit.

The technical solution of the utility model is: the circuit of forming with one-way SCR inserts in the main line, selects for use voltage-stabiliser tube to control the one-way SCR gate pole.Is more than the 100V according to trunk line voltage when the ring, is 48-60V when communicator is not worked, and is the characteristics about 12V during work, select the conducting of suitable resistance control voltage-stabiliser tube for use and end, thereby control silicon controlled break-make realizes the control of dialogue machine.Trunk line has the above voltage of 100V when outside line is dialled in, and the voltage-stabiliser tube conducting excites the controllable silicon gate pole, the communicator state of resuming work.When cross-over connection in the monitor circuit when voltage-stabiliser tube two end switch are in normally open, at this moment because of not conducting of voltage-stabiliser tube, phone can't be got.Only closing is added in the switch at voltage-stabiliser tube two ends, and controllable silicon just is excited, and circuit could recover normal operating conditions.Can realize controlling the dial-out of phone by the break-make of control switch.

Be to increase control device and insert additional digital circuit,, prevented that effectively the stranger from battering phone, realize automatic controlled function communicator if do not know then phone no dial tone all the time of predefined coding to circuit.

For preventing situations such as trunk line is stolen, adopt a NPN triode to make switching tube, be used for alarm control, design resistance serial connection dividing potential drop is as NPN management and control system voltage, the warning circuit working buzzer warning of ringing when circuit has into free call on sb. else's expense through illegal means.

Narrate technology contents of the present utility model and embodiment below in conjunction with accompanying drawing:

Trunk line L ₂With the whole D of bridge ₃, D ₄Be connected to contact 2, bridge is put in order D ₃Contact 3 links to each other L with communicator one end ₁Meet D ₄Contact 1 back connects the communicator other end.D ₃, D ₄Two positive poles meet R ₁, R ₄, the HCR positive pole, bridge is put in order D ₄Negative pole meets R ₃, BG ₁The e utmost point, BG ₂The e utmost point, buzzer Y one end and battery Ec negative pole, R ₁Another termination R ₂, D ₁Negative pole, DW negative pole, R ₂Another termination R ₃, R ₅, R ₅Another termination BG ₁The b utmost point, bridge is put in order D ₃Negative pole meets D ₁Anodal, C ₁Negative pole, HCR negative pole, the DW positive pole meets C ₁Positive pole and HCR gate pole, R ₄Another termination D ₂Positive pole, D ₂Negative pole meets R ₆, BG ₃The e utmost point, power supply Ec positive pole, R ₅Another termination BG ₁The c utmost point, BG ₂The b utmost point, BG ₂The c utmost point meets BG ₃The b utmost point, C ₂Cross-over connection BG ₂The other end of the b utmost point, buzzer Y and BG ₃The C utmost point, the K cross-over connection is in the DW two ends.

Fig. 2 is another embodiment of the present utility model: in the encrypted code circuit CH200 integrated package 4 pin are connect battery Ec negative pole, CH220 integrated package 8 pin connect the Ec positive pole, and 5 pin meet HCR gate pole, DW positive pole, C ₁Positive pole removes K switch ₀K ₁With the synchronous break-make of phone switch hook, K ₂The operation back disconnects with the protection phone accessing to your password.

Fig. 3 is another embodiment of the present utility model: remove and report to the police and digital circuit part, remove D again ₁, D ₄, R ₃, the D positive pole is met R ₁, the HCR positive pole, the D negative pole meets R ₂, C ₁With the HCR negative pole, the DW negative pole meets R ₁, R ₂Between, the DW positive pole meets C ₁Anodal, HCR gate pole, DW two termination K switch are with R ₂Numerical value 22K is adjusted into 24-27K, and other original paper numerical value is constant.The whole D input of bridge and output and trunk line L ₂Series connection inserts.Can become simple communication controller uses.

Provide the numerical value and the model of each element among this circuit embodiment below:

D ₁, D ₂Be IN4007, D ₃, D ₄For commercially available small-sized bridge heap (more than the 200V), DW are 1/2W24V, HCR100-6, BG ₁, BG ₂Be 9013, BG ₃Be 3Ax31, R ₁47K, R ₂22K, R ₃3.3K, R ₄150-18K, R ₅4.7K, R ₆22K, C ₁47uf/10V, C ₂0.1uf, the small-sized buzzer of Y, Ec2-4 save button cell.

This circuit has following advantage and effect:

(1) monitoring function:

K ₁When off-state, the outage of controllable silicon gate pole is outside communicator can't be dialed Line. When ring pair, telephone set is accepted the above voltage of 100V, owing to be higher than voltage-stabiliser tube The voltage stabilizing value, circuit recovers, and the K that do not close also can converse.

(2) warning function:

When circuit was in state of a control, if there is the people to connect secondary machine steathily on trunk line, as long as a use owner phone will be reported to the police immediately, the alarm signal bugle call can also reflect dialled the number or the ongoing situation of communication.

(3) steal warning:

When circuit is in state of a control,, cut off trunk line when stealing this communicator, so long time of alarm sound is sent in sound circuit work if the people is arranged because of can't using communicator or other factors.

This controller circuitry is simple, only forms supervisory circuits with more than 10 electronic original parts, just realizes Communication Control, the stolen automatic warning of communicator, connects and use that extension set is reported to the police automatically, monitored condition is pointed out automatically steathily, and extension set use state such as points out automatically at 10 functions.Have that microminiaturization, cost economize, low energy consumption, and can select advantage such as each function as required arbitrarily for use.Application and development has a extensive future, and can be widely applied in military affairs, each field electromechanical equipment control of industrial and agricultural production.In addition, this watch-dog can be selected normal operations control or cryptographic operation control mode arbitrarily, and it has overcome the drawback of traditional communication control unit, and communication apparatus is realized multi-faceted effective control.Be applicable to phone, fax, computer etc.
