Abstract

The utility model provides a many families networking burglar alarm of monitoring each other, it comprises a plurality of structures identical single burglar alarm, each single alarm by a plurality of alarm switch, encoding circuit, decoding circuit, delay circuit, anti jamming circuit, display circuit and audio circuit constitute, alarm switch arranges indoor hidden part in, any one family has the room for thief, can send out the alarm signal who definitely shows that family has the thief in all the other families immediately, many neighbours will make a concerted effort to support the capture thief. The original single-family anti-theft alarm with high danger for the thieves is changed into the multi-family combined anti-theft alarm, and the anti-theft alarm has the characteristics of mutual concern and safer and more reliable personal.

Description

Theft-proof alarm for many users

The utility model belongs to improved civilian alarm, particularly can be suitable for reporting to the police between the resident of many families with forming a burglar alarm net of monitoring mutually between the resident.

Now the civilian burglar alarm of separate unit that occurs on the market mainly is made up of trigger circuit, sound and light show circuit, and separate unit has a style of one's own, and can only monitor single-point by single-point, control point and the monitored some place that is everlasting.When anti-theft switch is touched by the robber, circuit is connected, and sends alerting signal immediately, and this signal can not only be learned by neighbours, and the thief perceives especially at first, and then destroys alarm.Neighbours are also because a variety of causes, as think normal sound equipment by mistake, are difficult for confirmation signal from what family, or are inherently safe etc., very likely ignore.Owner does not have any right and asks reprovingly.This chimes of doom does not only have prestige to pull together to the robber, can impel the robber to guard more on the contrary.Owner in case the robber swarms into, can not send an SOS to neighbours with alarm if be in, can only single household to the enemy, dangerous big.Installed also and performed practically no function, difficult can the popularization.

Task of the present utility model is that a kind of novel burglar alarm will be provided, and it can be joined together many families neighbours, forms a tight burglar alarm network, mutually monitoring.Can multi-point monitoring a bit; Again can the multi-point monitoring multiple spot.In a single day the thief enters the room, and will become inescapable situation.

This novel task is finished as follows:

This many families mutual monitor anti-theft warning device of networking is tied with the common wire by a plurality of identical in structure separate unit burglar alarms, form a burglar alarm networking, it is characterized in that each separate unit burglar alarm is by a plurality of alarm switches, coding circuit, decoding scheme, delay circuit, anti-jamming circuit, display circuit and acoustics circuit are formed, a plurality of alarm switches indoor concealed part that is placed in, the equal input coding circuit of its alerting signal, the coding circuit output terminal links to each other with the anti-jamming circuit input end, the anti-jamming circuit output terminal links to each other with the decoding scheme input end, decoded signal is delivered to delay circuit respectively, display circuit and acoustics circuit, the output signal of delay circuit is also delivered to acoustics circuit, each separate unit anti-jamming circuit all links to each other with the common wire, and the display on its panel links to each other with code translator corresponding encoded end becomes networking family numbering sign.Each household is respectively put one, be in alert status at ordinary times, in case certain family has the thief to enter the room, the alarm at this family can send the signal that certain family has the thief to enter the room to remaining each immediately, (and this family does not have any sound equipment, can not startle the robber), the alarm at all the other each families will send chimes of doom simultaneously, and demonstrates certain family have the thief to enter the room on the alarm panel; If owner is in, in case there is the thief to swarm into, can manage to touch the emergency switch at indoor concealed place, can reach the purpose that same warning is cried for help.The robber will be under neighbours' the power of comforming in a helpless situation being caught.

The utility model cost is low, manufacturing, easy to use, and effect is reliable.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Each separate unit alarm of Fig. 1 is with common wire's synoptic diagram of networking.

This burglar alarm of Fig. 2 block diagram.

Fig. 3 separate unit burglar alarm panel synoptic diagram.

Fig. 4 separate unit burglar alarm circuit diagram.

Fig. 1 is that common wire's 2 connections of each separate unit alarm 1 are a burglar alarm net.Wherein arbitrary separate unit can send own special-purpose numerical signal to all the other separate units, also can receive simultaneously all the other each signals that transmit, and make on the panel one among the corresponding red light emitting diodes D4～D11 of networking family number plate 3 to light after being discerned, represent that certain family has the thief to enter the room.

Among Fig. 3, coding circuit IC1, IC2 and line of codes M and BG1 form, and decoding scheme is that IC2, acoustics circuit are made up of IC3 and loudspeaker Y, and delay circuit is made of C7, R21, R22, anti-jamming circuit is made of R7, R10, C4, R13, C3, BG4 and IC2, and display circuit is made of D4-11.Coded signal is made up of the pulse of varying number, and the code clerk of a separate unit is represented in the pulse of default some, is 4 as the umber of pulse of No. 3 platforms, No. 7 platforms be 8 etc.When connection 220V power supply, the K1 that closes a switch, SCR triggerless voltage, not conducting, this moment, this separate unit 1 was in alert status.IC1 does not work; As if antitheft (emergency) K switch 2(K3) or K4 is touched, SCR conducting immediately, 4 pin of IC1 become noble potential by electronegative potential, export pulse since 3 pin, through BG2, each all the other separate unit of J1 send, stop output when reaching predefined pulse number, this predefined number is determined by the on line position (#1-#8) of each output terminal of line of codes M and IC2.Every separate unit occupies a coupled position, and all the other each pulse numbers of receiving promptly are the fixed number of this TV station.When the umber of pulse of 14 pin inputs reached default number, IC2 corresponding output end current potential raise from IC2, and encoded line M makes the BG1 conducting, and 7 pin of IC1 are clamped at electronegative potential, stop to export pulse.Decode procedure is: the signal of being sent here by public outside line, enter the 14th pin counting of IC2 through J1, after counting was finished, its corresponding output terminal was upgraded to noble potential, and lighting the red light emitting diodes (one of D4～D11) that joins with it immediately promptly is that reaction certain (family) has the police.Each red luminotron is represented the numbering of a separate unit (family), and D3 is a green luminotron, lights because of 3 pin of IC2 at ordinary times have output, and is normal to show.Sound circuit is made up of IC3 and loudspeaker y, is subjected to the 3 foot control systems of IC2, and 3 pin are not noble potential when having the police, and are noiseless; Have that 3 pin of IC2 become electronegative potential when alert, BG8 is ended, IC3 work, cross-talk device y sends chimes of doom.In order to guarantee that alarm has enough phonation times, this burglar alarm is provided with the chimes of doom delay circuit.3 pin by IC2 during early warning provide positive electricity to C7, have when alert, and C7 is by R21 and R22, BG7 discharge, when C7 discharges into certain value, BG10 quits work acoustics circuit by by 2 pin that transfer IC3 in the conducting control acoustics circuit to, and be the sound equipment time-delay closing time discharge time of its C7.Anti-jamming circuit is formed three kinds of anti-jamming circuits jointly by R7, R10, C4, R13C3, BG4 and IC2, to guarantee the operate as normal of this device.
