Abstract

The utility model provides a long-range alarm. The utility model has the technical proposal that an alarm main board is arranged in a telephone set, a relay J1 is connected to a hand-free key in parallel, a relay J2 is connected to a memory key in parallel, and a normally-opened contact of the J2 is connected with a connecting line between a control switch and the hand-free key in series. The long-range alarm has the advantages of simple structure, low cost, economy and practicality, and transmits information through a telephone line; if the door is opened without opening a coded lock, a BP call can sound to display identification codes preset by a master within the coverage area of the master's BP call. The long-range alarm can be arranged on the existing telephone set, can also be arranged by a telephone manufacturer when the telephone set is produced, can be popularized and used in common families, and is also suitable for other places requiring protection, such as offices, etc.

Description

Long-distance alarm apparatus

The utility model relates to a kind of warning device, especially a kind of household long-range alarm.

Because the influence of various social factors, home dwelling is antitheft to be the people's attention main points always, various antitheft doors, " opal " monitoring, video doorbell, burglar alarm or the like, arise at the historic moment, but effect is warning system many, the complex structure of function often preferably, expensive, generally be not that average family can be accepted.The device that adopts telephone line to come transmission information to be used for the home security warning still is not reported and does not see that product appears on the market.

As long as the purpose of this utility model provides a kind of people of having and does not open coded lock and open the door, the warning mainboard that is contained on the telephone set will send alerting signal by telephone line to owner's beeper automatically, and is safe and efficient, simple in structure, cost is low, the long-distance alarm apparatus that makes things convenient for family to use.

The utility model is achieved in that by warning mainboard, telephone set, coded lock, gauge tap four major parts to be formed.The warning mainboard is contained in the telephone set, relay J ₁Be attempted by on the Hands-free key J ₂Be connected in parallel on the memory button J ₂The normal open contact be connected in gauge tap between the line of Hands-free key.

This alarm is simple in structure, and it is installed in the telephone set, comes transmission information by telephone wire, and during startup, it puts through any phone, mobile phone or a beeper automatically, closes automatically after operation is finished, and does not influence the normal use of phone.As do not open coded lock and open the door, the gauge tap contact is connected, and no matter when and where, so long as in owner's beeper coverage, beeper will ring, and demonstrates the identification code of making by oneself in advance, and like this, the machine master just can make Corresponding Countermeasures, exempts from disaster.This alarm can install additional on existing phone, loads onto in the time of also can be by the telephone set manufacturer production, and cost is low, and is economical and practical, and average family all can be promoted the use of, and also is applicable to the place that office etc. needs protection.

Be described in further detail below in conjunction with accompanying drawing.

Fig. 6 is the utility model alarm mainboard stereographic map.

This alarm is by the warning mainboard, telephone set, coded lock, gauge tap four most of compositions.The warning mainboard is contained in the telephone set, and it is by a triode Q, an electrochemical capacitor C, a resistance R and two relay J ₁, J ₂Form J ₁Normal battle be connected in parallel on the Hands-free key of finger-board J ₂Normal battle be connected in parallel on the memory button of appointment J ₂Be connected on which key, which key waits to dial the number just deposits in J in ₂The normal open point be to be serially connected in gauge tap between the line of Hands-free key.Gauge tap K ₁Be installed in the door and window place.The coded lock keyboard portion is contained in outdoors, power supply and J ₃Dress can prevent that like this burglar from unblanking J at short circuit outdoors indoor ₃The normal open point be connected on gauge tap to J ₂Normal open point between, K ₂Be J ₂Normal battle, K ₃Be J ₁Normal battle, K ₄Be J ₃The normal open point, K ₅Be J ₂Normal open point, KEY1 are memory button, and KEY2 is a Hands-free key.

Can be earlier selected voluntarily beeper of alarm owner number and identification code deposit in the memory button of appointment it stand-by.Gauge tap is installed in controlled place, and as door, window, a machine can be adorned many gauge tap, guides to phone with diatom, is connected in parallel on the hands-free switch of keyboard, as long as contact one touching, hand-free function promptly starts, quite by a Hands-free key, and J ₂Normal battle be connected on the memory button, the power supply supply has been arranged, J after the hands-free startup ₂Action, the normal battle connected, and quite by a memory button, transfers to the number of having deposited, simultaneously J ₂Normal open point disconnect, avoid turning off hands-free from the interference of gauge tap, guarantee that this time breathe out successfully.Q, C, R and J ₁Form delay circuit, after exhalation is finished, J ₁Inhale movingly, the normal battle connected, and turns off hands-freely, restPoses.J ₃Receive coded lock, password is by right when opening the door, and J3 inhales moving, and normal open point disconnects, though gauge tap is also connected, can't form the loop, can not breathe out, and reaches the effect that can recognize the people on one's own side.

J is a relay, and 3 to 5 volts of trigger voltages are regulated the length that R can change delay time, and the alarm power supply is with hands-free power supply, picks out through the P/T switch.In view of present China mostly uses dual-tone dialing, it is unnecessary that the P/T switch has become, can utilize this switch, and pushing T is warning usefulness, and this moment can not be with hands-free, and pushing P is the original function of phone., can only make dispositions in addition in the place of using pulse dialing as also.

The principle of work of coded lock is: embodiment as shown in the figure, the password of this lock is " 9805 ", each silicon controlled anode is all received positive supply, the plus earth of VT1, when pressing " 9 ", VT1 adds that because of its control utmost point the trigger pip road is logical, and this moment, the negative electrode of VT2 passed through the logical controllable silicon ground connection in first road, press " 8 ", also the road is logical for second controllable silicon.In like manner, make the 3rd, the 4th controllable silicon road logical again, pilot lamp is bright, the actuating of relay simultaneously, and contact disconnects, and the line of gauge tap to phone cut off, and the beeper that opens the door this moment does not ring.1,2,3,4,6,7 is reset key, in the process of unblanking, as its any key in pressing, all will make the control utmost point ground connection of VT1 and turn-offs, and reaches to destroy and unblanks.The value of each element and each element does not have specific (special) requirements in the circuit.

Claims (1)

1, a kind of long-distance alarm apparatus is made up of warning mainboard, coded lock, gauge tap, it is characterized in that: the warning mainboard is contained in the telephone set, relay J ₁Be attempted by on the Hands-free key J ₂Be connected in parallel on the memory button J ₂The normal open contact be connected in gauge tap between the line of Hands-free key.
