Background technology

" security personnel " are the important symbols of happy index, anti-theft safety door be use the most a kind of security personnel's equipment, it is applicable to each family basically.

Ensure public security both important because it is the basis of life, the face that security personnel relate to is also very wide, and list is opinion with family, just relates to hundreds of millions families, so have great significance, the inventor is ready to carry out its research with bigger energy, and hope can have effect preferably.

Anti-theft safety door is to can use the most general security personnel's equipment in the society.Its biggest advantage is, it is protecting important within doors access site---Men, if can not crack it, it just can be kept outside the door reliably non-personnel within doors.The user feels safe relieved, and it is also convenient to use simultaneously, it be a kind of most important also be basic and the most essential a kind of protection.

But the anti-theft safety door major defect is a kind of protection of passive type, and its implication is, if objectively unmanned on the scene again, and when the crime behavior is arranged, then can only " passive " and wait for destroyed " helpless ".And the crime behavior has the sound of movement mode of savagely forcing open the door significantly, also there is sound littlely to crack the form that lockhole is started with " civilization ", means are increasing, unsafe factor is strengthening, in allegro today, young man is busy with work, and the old men will go out to lie fallow, situation unmanned in the family is everlasting, and unmanned all around situation also is not difficult to produce.So objectively created condition for the crime behavior.The shortcoming that security door exposed also appears gradually.

Imagination if security door has the function of alarm, can obviously can reduce to minimum to loss in advance with the house owner people outside of not accomplished crime behavior announcement.

At present in the product, though there are a lot of alarms, the advantage of alarm is the weakness that can remedy the anti-theft safety door passive protection, its greatest weakness have following some:

1, do not possess non-personnel within doors the most important basic functions of keeping outside the door.

2, a lot of alarms do not possess the function of excellent in performance telephone call, the not outstanding implication one of performance is can not reliably solve the problem of correct identification, as sound letter sensor, can not tell exactly is the sound that sends of people within doors, or the sound that sends of criminal; As the signal that infrared ray sensor takes out, can not tell one of own side or other people accurately, other tactile sensor etc. and for example all exists the problem of accurate resolution.Wrong report brings in terror to the people, and this is in lifely least to want to take place.The 2nd, though or can discern, certain additional program and formality must be increased before each the use, otherwise it is unreliable to report to the police for the second time.The 3rd, be not equipped with no telephone alarm function, promptly be there is warning function, but can only be that wherein a receiver is received signal, and can not be that the multi-section receiver is received signal simultaneously that the warning dynamics weakens greatly.These have all seriously influenced the warning function effect.

3, present senior product often has (maybe must have) wireless link link, and produce the device radio transmission now mainly is to adopt the solid size radiating circuit emission that coding is arranged, this is feasible for general household electrical appliances, but can not satisfy the requirement of precision for the product of higher gears, not only because social now upward wireless remotecontrol has been widely used in various fields, as the lock of locking of automobile burglar, all will use remote control, and these all become wide interference source.Also there is artificial instrument interference and cracks.The problem of disturbing for solving if adopt high-grade coding integrated circuit, relates to serial problems such as cost again, therefore encodes with which type of and realizes thoroughly stopping all interference in the society, and reach the low again purpose of cost, also becomes a difficult problem.

Also find to have following difficult point in research process: test shows that the distance of emission is that sensitivity one is to have a significant impact with weather, and fair weather is then effective, and bad weather is poor effect then; The 2nd, with the environment in place very big influence is arranged, local effective as in spaciousness, and just special poor in the many places of cover material.Emission of the present invention and receive between is not the ground of spaciousness, and between a lot of cover materials are arranged, as furniture etc.If put receive body more hiddenly, environment can be more complicated.So the present invention has very high requirement to the requirement of sensitivity, if, then be difficult to satisfy with traditional method for designing.Its reason is, therefore the position that a lot of products can the Iterim Change emission can both receive between the two.And in a single day emission of the present invention and receiving position are determined, and run into bad weather, and performance will be challenged, and therefore should have what kind of measure could satisfy designing requirement.

The society the development, the product needed progress, market demand is enriched the kind of alarm and anti-theft safety door, the new product that more needs anti-theft safety door to combine with alarm, bring to the user safer, more reliable fail-safe.

Need the compound of multiple technologies but address this problem, need the innovation of technology, be difficult to for a long time break through, do not properly settled all the time.

At first will make the following instructions, so that the clear meaning of understanding the technical program:

The inventor has done to study for a long period of time to anti-theft safety door, and anti-theft safety door has arrived the stage of following progress:

The firstth, normal door is opened the door without mechanical key, but the mode of opening the door with electronics telecontrol engineering or phone.When normal door, be installed on the power set in the door, will promote the lockset action, realize opening the door.Meanwhile, still kept the form that mechanical key opens the door, its objective is to have a kind of opening the door to remedy when automatic system goes wrong.This promptly is if open the door with mechanical key, and great majority are to want also to be the situation that needs telephone call by joining the situation of mechanical key crime.And a few cases is own oneself to want the situation of opening the door with mechanical key because of electrical equipment goes wrong, but this situation is own clearly situation on the scene, produces alert sound and oneself does not also feel fearful and nervous.

The secondth, have identification circuit, can correctly discern is the situation of crime behavior or owner's normal door.Its reason is that the behavior of opening the door normally is to open the door with electronic technology, rather than opens the door with mechanical key.When normal method was opened the door with electronics, the identification circuit input had electronic signal, and the no electronic signal of crime behavior identification circuit input will start warning system.

For this reason, existing meaning to each technical measures of the present invention, concrete condition further is explained as follows:

One, the switch of being pacified in the measure scheme one is the key component that warning of the present invention starts, and also is a bright spot of the present invention, because after the existing achievement of this part and inventor cooperatively interacts, making warning of the present invention accomplish more science, also is the place different with a lot of alarms, and its reason is:

1, can generation not make us terrified wrong report, this is the most important.Its reason is, the door that is absent from the scene of owner is opened (opening with improper door) within doors, or opens the door by lockhole with ' key ', all is crime behaviors, and warning at this moment all is very significant.

2, very reliable, because, do not need artificial additional move, do not influence the normal habits and customs of people, thereby do not influence the operate as normal of the each starting of security system the opening the door at closing time of normal life.

3, the warning firing switch is sensitive and reliable, can just report to the police when the crime behavior is not accomplished, thereby loss is reduced to minimum.The initiating signal of reporting to the police because the switch contact when lockhole cap is becoming flexible on the lockhole will change.If in like manner the door and doorframe this be subjected to displacement, the switch of pacifying this place also can start alarm signal immediately.

Two, be positioned on the warning starting on a ground, telephone call adopts wireless remotecontrol to get in touch with being placed within doors, so telephone call is laid a little arbitrarily, has strengthened confidentiality.

Three, after the processing in the information processing part following function is arranged among the present invention, the one, can store a plurality of telephone numbers, under the situation that oneself storage finishes in advance, (the present invention can utilize former existing phone that this integrated circuit is stored), as long as programming start device starting, all store the phone signal that signals will be transferred in the phone to be stored automatically telephone.And such characteristics are arranged, and the one, together with can both notifying from a phone call, rather than only notify from a phone call wherein one one to each phone, improved the dynamics of notifying from a phone call, the 2nd, can listen to on-the-spot certain situation, strengthened telephone alarm function.

Four, the program circuit in this unit can be made of a variety of circuits, the Copper Foil that the Hands-free key of the telephone in its first output and this part is corresponding links to each other, other output links to each other with the key of respectively storing of phone respectively, the program control rule that forms is, first output is the high-order Hands-free key of opening base of output at first, produce the off-hook program, trigger the first storage number pin in the phone again; Call out first receiver conversation; As method repeatedly, all store all receiver numbers in keys can to call out out phone.

Five, owing to adopted the startup of reporting to the police, the two-part combination closely of telephone call in the technical scheme one, just formed such defence program and protection philosophy, just often anti-theft safety door is kept other people outside the door.When committing a crime by lockhole, in case open lockhole cap, be loaded on locking closure and the door between switch can because magnet away from and the contact changes, the constant close contact of switch will become the signalling state, through the identification of lines of this bright person in being fruitful, conclude whether this warning.Report to the police if belong to, can produce two functions, a kind of function is to connect to promote alert acoustic-electric source, produces onsite alarming, and caution is caused at the scene, prior a kind of function is to be positioned on the controlled emissions plate radiating circuit starting of security door part, after the reception dress is received and is transmitted, the warning that produces the multi-section phone, the owner of notice mobile phone, in time determine, with processing.Loss is reduced to minimum, or remedy.

Six, in technical scheme 1, implemented the wireless remotecontrol emission, test shows, the distance of emission is that sensitivity and weather have a significant impact, and the present invention is very high to the requirement of sensitivity, if with traditional method for designing, designing requirement of the present invention is satisfied in very difficult assurance, its reason is, general emission can Iterim Change the position and the distance of emission, can receive that signal just could as long as can satisfy reception at that time.And emission of the present invention and receiving position are definite, can not be in use because of the interim change of the difference of weather, (can influence like that normal life is breezy is used to) is in case when bad weather, just be difficult to guarantee the performance of product, so the essential measures necessary that increases.And the present invention can largely improve sensitivity, and promptly being increases external antenna to improve sensitivity, but will increase external antenna, must do certain processing to radiating circuit, so just can reach best effect.The first must increase an electric capacity, isolates with antenna.It two is that this electric capacity must be welded in a special position, this position must be to be an end of high-frequency emission pipe collector at the antenna Copper Foil output at printed panel, and can not be in other place, this external antenna can replace with one long 30 centimetres long line, use such benefit to be, existing good reception also is convenient to install, because long line can be placed in the mounting box.

After the invention process, security door will present a kind of brand-new looks, and following outstanding advantage is arranged:

1, after the invention process; anti-theft safety door has been realized combining of science with alarm; the advantage that has possessed two kinds of protectors; usually both can keep the people outside the door; when running into other people and committing a crime; can send two kinds of cautions; to increasing " the initiatively protectiveness " of anti-theft safety door; (its implication is; function of the present invention will produce the crime behavior and suppress; and whether waiting for its destruction passively) all be very significant, the situation of the passive defence of anti-theft safety door so this product is through with has fully promoted security personnel's performance of anti-theft safety door all sidedly.

2, the warning system partial properties is very excellent, is most valuable for alarm, embodies in the following areas:

The one, warning system can not reported by mistake fully.Because after existing achievement cooperates, has automatic recognition property.The warning that produces when owner is absent from the scene may be the crime behavior only.Otherwise the behavior of not committing a crime, the warning firing switch can not send signal, at this moment because the structures shape of switch is installed.Because the intrinsic property of switch, when shift knob takes place the variation of contact must take place when not suffering oppression being subjected to oppressing.

The 2nd, reliable, its reason one is, without any need for other additional move, thereby warning system all is in a kind of " highly waiting " state to the user at any time when closing the door and open, do not need any preparation, the 2nd, the malfunctioning chance of mechanical switch can be far superior to electronic component.

Three are to use conveniently.Do not influence normal habits and customs after the installation fully.If increased trouble with former life, obviously the shortcoming of bringing to the people is or is to use inconvenience, or has forgotten operations necessary and bring the malfunction of warning or malfunctioning.

The 4th, protection is tight, has prevented to crack the practice of lockhole crime.

The 5th, on-the-spot and two kinds of warnings of phone are arranged, deterrent force is bigger, and is used because both complementations respectively have.

3, single also have following characteristic with regard to telephone call:

One of be the warning great efforts, can store 2 phones sends out simultaneously, such benefit one is to carry out Advise By Wire to personnel outside, the 2nd, both can call out the mobile phone of carrying, can call out the fixed line phone in relevant place again, can be will reducing to minimum to the various objective factors that are unfavorable for Advise By Wire, even stop fully.

Two persons that are the acknowledge(ment) signal can hear the language or the alert sound of warning, and can listen to the scene.

Three be easy production, the one because report to the police part and telephone unification, can save many circuit, as general off-hook element circuit, store the keypad of number etc., and the part that is increased is very limited, the 2nd, used element all belongs to part commonly used.

Four, can accomplish a tractor serves several purposes, the telephone after the repacking promptly is a kind of telephone alarm, but still has kept all properties of telephone, still can make communication telephones usefulness, such largest benefit is that family does not have too much device ornaments and to influence family attractive in appearance.

4, can realize coupling well between emission and the reception, promote distance between the two greatly.Radio transmission and receive between good effect is arranged, receiving unit can be put more hiddenly, and laying of being in a little brought more selection, the while also can be to the secret space that provides a little be provided.
