Description

The electronic anti-theft net that laser adjustment orientation and tamper-proof function are arranged

The utility model is the electronic anti-theft net that laser adjustment orientation and tamper-proof function are arranged, and belongs to the automatic monitor anti-theft warning technology of infrared ray.

Along with the development of public security situation, over past ten years, the domestic premises in many towns have all been installed the anti-theft net of metal mesh type, this to the safety of resident family and antitheft once play a part really certain.But As time goes on, the anti-theft net of this metal mesh type also more and more exposes its shortcoming: for example, 1. the ruffian can utilize anti-theft net do ladder from Stall climb to second floor, the 3rd buildings enter each floor crime from balcony stair mouth or other flame proof passageways then up to roof; 2. the meeting corrosion was pounded down and is hurted sb.'s feelings after anti-theft net used for many years; 3. as aviary one by one, diminish city image; 4. anti-theft net is also unreliable, strikes promptly with sledgehammer one to get loose, and just can go into the room crime.As just welding " hand is opened to net " especially with large size reinforcing bar pincers or miniature wind.So in fact strict, anti-theft net also equals to perform practically no function and be unreliable, in fact, its psychological application is much larger than practical function.And even more serious be that the whole nation has taken place a lot ofly to make the people that the meet fire hopeless cost of paying blood of escaping because of the obstruct of metal mesh type anti-theft net when running into fire.Therefore, over the past two years, many local governments have expressly provided will remove existing anti-theft net.But after anti-theft net is removed, also bring some practical problemss really: at first be the psychological problems of resident family, think that anti-theft net removed, lost a retaining thief's net, feel very dangerous, thereby on tenterhooks whole night, it is not stable to sleep; The 2nd, after anti-theft net was removed, opened greatly at " holes " such as balcony, windows, also really makes the unprincipled fellow come in and go out easily.For this reason, people have expected the problem of technological prevention, for example passive infrared in indoor installation, microwave, electronic alarms such as ultrasound wave, or comprehensively the two of these technology supervise, three prison formula electronic anti-theft alarms, or at outdoor mounted active infra-red line correlation electronic anti-theft alarm etc., the function that can't replace original anti-theft net but existing these electronic anti-theft alarms also have its many unsatisfactory weak points fully, main cause is passive infrared, microwave, when all having a common weakness to be exactly the indoor one of own side of having, just can not enable electronic anti-theft alarms such as ultrasound wave, otherwise will false alarm, the long warning.And resident family generally has the Room that the room is arranged, and goes into to such an extent that the room comes the Room unmanned or go out to such an extent that the Room comes the room unmanned, though or have the people to exist, be absorbed in and see TV etc., so that the ruffian climbs window and has come in also not know.And, generally all exist detection " blind area " again for most of indoor type alarms.So " for net " effect of this electron-like burglar alarm is just had a greatly reduced quality.And for having the effect that also there is the shortcoming of following several respects in the active infra-red line burglar alarm (promptly the someone is referred to as the correlation burglar alarm) that can be used for outdoor mounted and can't plays the generation net fully now.These shortcomings are exactly: (1) existing correlation burglar alarm is some correlation or 2 correlation mostly just, and the pretective acreage size is not enough to become " net ", and its protective action is quite limited.Certainly, a plurality of somes correlation burglar alarms also can be installed in order to networking.But but can produce new practical problems: the one, emission receives existing all identical correlation burglar alarm of structure, and the problem of phase mutual interference may appear in the combination dress time spent.And so much probe to be installed together, each minimum three or four extension line of popping one's head in will connect tens lead-in wires altogether and also quite bother; On the other hand, the structural design of existing correlation alarm all is in the majority by being applied to indoor consideration, use the short and small shell of plastic production mostly, be unable to undergo outdoor long-term exposing to wind and rain at all, and owing to be the branch body structure, adopt the total cost of a plurality of splits high too, make that general resident family is unable to be born.In addition, most correlation infrared emission probe all is to adopt common pulsed modulation mode at present, and natural light is still had certain anti-interference effect.But electricity, magnetic, light are disturbed, disturb then powerless as light to the daylight lamp that uses electric ballast, in addition, existing correlation burglar alarm, its " light path " all is invisible light, so its emitting head is not directly perceived with " correlation " state that receives head, the adjustment of transmitting-receiving alignment orientation is pretty troublesome.So existing all kinds of burglar alarms also all can not play the effect of alternative metals net formula anti-theft net fully.

The purpose of this utility model be exactly for overcome and solve because of the metal anti-theft net because of easily being utilized by the robber, meeting long neglected and in disrepair is hurted sb.'s feelings and is unfavorablely escaped calamity danger and after being removed, there is the blind area in existing various electronic anti-theft net, pretective acreage is little, the function that can't replace the metal anti-theft net fully, and it is anti-, magnetic, the light interference performance is poor, install numerous and diverse, the adjustment difficulty, the cost height, cost an arm and a leg, shortcoming and problem that user's impotentia is born etc., research and design is a kind of by loseing the large tracts of land opposite house that light is formed, it is antitheft that window blocks monitor-type entirely, antijamming capability is strong, the reliability height, install simple, adjustment is easy, cost is lower, the electronic anti-theft net that laser adjustment orientation and tamper-proof function are arranged that acousto-optic is reported to the police simultaneously.
