Description
[technical field]
The present invention relates to a kind of infrared anti-theft net control method, particularly relates to a kind of intelligent adjusting method of the infrared anti-theft net that can in good time adjust according to actual environment and demand.
[background technology]
Patent of invention number is ZL99117200.0 " infrared anti-theft net ", disclose a kind of infrared transmitter (transmitting terminal) all has been installed at one end, and infrared receiver all is installed in the other end (receiving end), technology by " the I/O mouth of CPU (single-chip microcomputer) control infrared transmitter and infrared receiver; the coded system of the pulse ray between the every pair of infrared transmitter/infrared receiver is different fully ", effectively realize the identification of infrared receiver under the mutual coverage condition of multi beam infrared ray beam, reach the purpose that improves infrared intrusion detector defence height, having constituted can be to window, balcony is implemented the effectively infrared anti-theft net of strick precaution.
Publication number is the patent of invention " correlation infrared anti-theft net " of CN1624725, the structure of another kind of " infrared transmitter and infrared receiver adopt the correlation that disposes simultaneously at the device two ends " is proposed, utilize sunlight and the unidirectional infrared radiation source infrared anti-theft net of direct projection simultaneously that the characteristics at two ends are installed opposite one another, when sunlight and the source direct projection of unidirectional infrared radiation during to a certain end, the infrared receiver of this end can be interfered, and the infrared receiver of opposite end is shone by sunlight and unidirectional infrared radiation source can scarcely.At this moment the infrared receiver of opposite end still can provide useful signal to subsequent components, make subsequent components neither can produce false alarm, can accurately forecast invasion by monitoring again, thereby reach the purpose that infrared anti-theft net is not disturbed by sunlight and the irradiation of unidirectional infrared radiation source fully useful signal.
More than two patents are the most representative technology at present.But find that in force prior art can't solve following several situation: at first be that whether infrared receiver only detects receives the infrared pulse signal, and can not detect the intensity that it receives the infrared pulse signal.In actual production process, because the discreteness of components and parts and the distributivity of production technology, make the intensity consistance of the infrared pulse signal that each infrared receiver receives poor.Next is, the intensity of the infrared pulse signal that infrared transmitter is sent is to send according to predetermined design margin that (because a large amount of disturbing factors is arranged in the outdoor environment for use: rain, snow, mist, water vapor, sunlight, dirt accumulation, plant growth are blocked etc., and these factors all can produce decay or stop the infrared pulse signal intensity.In order to overcome the false alarm that these factors may cause, prior art has adopted the method for the intensity that strengthens the infrared pulse signal that infrared transmitter sends, and makes the intensity of the infrared pulse signal that infrared transmitter is in actual use sent contain a large amount of design margin intensity.The infrared pulse signal of the design margin intensity that these are a large amount of in that product is intensive when installing and using, becomes the signal that product interferes with each other again.More than two kinds of defectives at first make product when work because the discreteness of component parameter and the distributivity of product processes cause each infrared receiver to receive that the consistance of infrared pulse signal intensity is poor, thereby make product integral body consistance poor.Secondly, product in use not only has environmental factor to disturb but also have unavoidably the fault generation, because prior art can not accurately detect the intensity that it receives the infrared pulse signal, so can't carry out the function of self check to the product duty, thereby easily because of accurately not aiming at, certain light path has fault, be subjected to various environmental interference, or during intensive installation in enormous quantities, the infrared pulse signal that each infrared transmitter gives out a large amount of design margin intensity in the integrated environment space interferes with each other etc. former thereby causes false alarm, and perhaps the infrared pulse signal of a large amount of design margin intensity is owing to reflect to cause and fail to report the police.
Therefore, prior art is improved, providing a kind of can be necessity in fact according to the intelligent adjusting method of actual environment and the in good time infrared anti-theft net of adjusting of demand.
[summary of the invention]
The purpose of this invention is to provide a kind of easy to operate, can detect the infrared pulse signal intensity, and can in time regulate the infrared pulse signal intensity according to testing result, overcome the false alarm situation that environment and other factor affecting cause, realize accurately aiming at, and prevent the caused false alarm of a large amount of infrared pulse signal margin Intensity Design, fail to report the intelligent adjusting method of alert infrared anti-theft net.
To achieve these goals, the present invention adopts following technical scheme:
A kind of intelligent adjusting method of infrared anti-theft net is provided,, regulates and control the infrared pulse signal intensity that corresponding infrared transmitter is launched by comparison to the requirements of infrared pulse signal intensity that infrared receiver received and setting.Utilize each infrared receiver of measurement to receive the infrared pulse signal intensity, can realize corresponding the adjusting to the infrared pulse signal intensity that each infrared transmitter is launched, make each infrared receiver receive the intensity of infrared pulse signal can to reach the requirements of use that (fixed value dynamically be adjusted or be got to this value can with actual needs.And under normal conditions, can if the requirements of usefulness equate).By the infrared pulse signal intensity that the regulation and control infrared transmitter is launched, under different service conditions, the infrared pulse signal intensity that infrared receiver received can have consistance, also can have difference.
The intelligent adjusting method of this infrared anti-theft net specifically further comprises the steps:
(1) requirements of the infrared pulse signal intensity of setting each infrared receiver and being received;
(2) detect the infrared pulse signal intensity of each infrared receiver institute actual reception;
(3) compare actual detected value and preset need value;
(4) regulate and control the infrared pulse signal intensity that corresponding infrared transmitter is launched according to comparative result.
Receive the method for the requirements that the infrared pulse signal uses by preestablishing infrared receiver, make corresponding infrared transmitter send the infrared pulse signal of suitable intensity, and when environmental change need strengthen, suitably strengthen again, perhaps when need weakening, environmental change suitably weakens again, a large amount of design margin intensity just need not be sent fully in the infrared pulse signal that infrared transmitter is sent like this, when making intensive installation in the integrated environment space each infrared transmitter give out a large amount of design margin intensity and reduce greatly, thereby the infrared pulse signal interferes with each other when having reduced intensive installation.
Measure each infrared receiver and receive the method for the intensity of infrared pulse signal, specifically be by microprocessor directly or indirectly detect the intensity of the received infrared pulse signal of infrared receiver and the electric weight exported as electrical quantitys such as voltage, electric current, pulsewidths, and compare with the requirements of setting, received the power of infrared pulse signal intensity and requirements to distinguish each infrared receiver.What is called directly detects and is meant that the microprocessor input port directly connects the output terminal of infrared receiver and its output electric weight is carried out detection, and indirect detection is meant the microprocessor input port through circuit or devices such as other treatment circuits or device such as amplification, shaping, isolation, is connected with the infrared receiver output terminal and its output electric weight is carried out detection.
Control the method for the infrared pulse signal intensity that each infrared transmitter sends, specifically be to be connected with infrared transmitter through other treatment circuits or device such as power driving circuit or device by the delivery outlet of microprocessor, and by microprocessor by treatment circuit or device to the electrical quantity of infrared transmitter as: voltage, current's intensity are implemented control, thus the infrared pulse signal intensity that the control infrared transmitter is sent.
This unanimity of reference value strong basis of being received the infrared pulse signal with each infrared receiver is an example, the output electric energy control of the course of work to corresponding each infrared transmitter is described, detailed process is: when a certain infrared receiver receives that its corresponding reference value of infrared pulse signal intensity comparison is strong, controlling the infrared pulse signal intensity that corresponding infrared transmitter with it sends dies down, thereby make this infrared receiver receive that the infrared pulse signal strength weakening is approaching to the reference value corresponding with it, and the like make all infrared receivers receive that all corresponding with it reference value of infrared pulse signal intensity is approaching; Otherwise, when a certain infrared receiver receives that the infrared pulse signal intensity reference value corresponding with it is more weak, control the infrared pulse signal intensity enhancing that corresponding infrared transmitter with it is sent, thereby make this infrared receiver receive that infrared pulse signal intensity grow is approaching to the reference value corresponding with it, and the like make all infrared receivers receive that all corresponding with it reference value of infrared pulse signal intensity is approaching; So just can make each infrared receiver receive infrared pulse signal intensity basically identical.
It can also cooperate employing, receives that according to each infrared receiver the intensity of infrared pulse signal carries out signal intensity indication, makes product have the prompting directly perceived of Aligning degree, makes things convenient for user's alignment function.Indicating means can adopt sound or light or electric signal indication.And can receive that the infrared pulse signal intensity produces fault alarm according to infrared receiver.
When in correspondence with each other infrared transmitter and infrared receiver Aligning degree are high more, aim at and indicate variation or data-signal and the electrical quantity (by microprocessor control hummer, luminotron, direct output data and electrical parameter measuring instrument) that produces with very not big prompting amount (as sound or light) intensity punctual contrast, otherwise when in correspondence with each other infrared transmitter and infrared receiver Aligning degree are low more, aim at indication and produce variation or data-signal with the prompting amount very big (as sound or light, electrical quantity) intensity punctual contrast.The user is by judging prompting amount (as sound, light, the electrical quantity) variation that intensity produced or by data-signal (by microprocessor control hummer, luminotron or direct output data and observation electrical parameter measuring instrument), just can carrying out alignment function intuitively.
The in use regular received infrared pulse signal intensity of each infrared receiver of start detection, the infrared pulse signal intensity that cooperates each infrared transmitter of control to send, the environmental factor that the intensity of the infrared pulse signal that each infrared transmitter sends can be adapted to slowly change as: rain, snow, mist, water vapor, sunlight, dirt accumulation, plant growth such as block at the attenuation change that the infrared pulse signal intensity is produced, and avoid the generation of false alarm.
When sending the strongest infrared pulse signal for infrared transmitter, the received signal of corresponding infrared receiver is far below the requirements that uses or when being zero, stopping this infrared receiver participates in reporting to the police, changing by its adjacent two infrared receivers cooperates participation to report to the police, and the method for this infrared receiver (light path) fault prompting is sent in employing, make product both can not produce false alarm, can avoid again producing and fail to report the police.
To various fault judgement, shielding.When detecting certain infrared receiver and receive that the intensity of infrared pulse signal is zero, can judge that this infrared pulse signal beam is blocked by obstacles such as plant growths or some corresponding components and parts break down, at this moment microprocessor shields the pairing components and parts of this infrared pulse signal beam, changes by two light beams that are adjacent to be blocked simultaneously and trigger alerting signal and export; When various faults are judged, are shielded, to various fault reminding methods: both can be by sound or light (by microprocessor control hummer or luminotron indication) or data-signal (the related data of directly sending by microprocessor) about fault, the position of the infrared light beam that prompting is broken down and even the reason of fault, these promptings can help the user of service in time and easily to keep in repair.
Compared with prior art, the present invention has following beneficial effect:
Adopt the consistance of the infrared anti-theft net of intelligent adjusting method of the present invention to be improved, alignment function is directly perceived and accurate, when in use running into fault, anti-theft net not only can work on, and can not produce false alarm and fault and can also obtain prompting, at the scene it is safeguarded with convenient.The infrared pulse signal interferes with each other and weakens during intensive installation, make product false alarm, fail to report alert phenomenon and reduced.Cost can not improve substantially compared with the prior art.

Fig. 1 is the process flow diagram of the intelligent adjusting method of infrared anti-theft net of the present invention.
[embodiment]
As shown in Figure 1, the intelligent adjusting method of infrared anti-theft net of the present invention is the infrared pulse signal intensity of launching by the regulation and control infrared transmitter, make that under different external conditions, the infrared pulse signal intensity that infrared receiver received has consistance.
It specifically comprises the steps:
(1) requirements of the infrared pulse signal intensity of setting each infrared receiver and being received;
(2) detect the infrared pulse signal intensity of each infrared receiver institute actual reception;
(3) compare actual detected value and preset need value;
(4) regulate and control the infrared pulse signal intensity that corresponding infrared transmitter is launched according to comparative result.
In concrete operations, can be when first energising being installed, the infrared pulse signal intensity that each infrared transmitter is sent begins to be maximum, receive the intensity of infrared pulse signal by measuring each infrared receiver, can measure each infrared receiver and receive that the intensity of infrared pulse signal is all above reference value; Reduce output intensity in conjunction with each analog line driver of control, thereby the infrared pulse signal intensity that each infrared transmitter is sent is progressively decayed, the intensity of receiving the infrared pulse signal up to each infrared receiver is during all near reference value, stops measuring/adjustment process and send the prompting that enters operate as normal.
During alignment function, measure the intensity that each infrared receiver is received the infrared pulse signal simultaneously, and the infrared pulse signal intensity made indication, when in correspondence with each other infrared transmitter and infrared receiver Aligning degree are high more, the sound that hummer sends is close more, otherwise when in correspondence with each other infrared transmitter and infrared receiver Aligning degree were low more, the sound that hummer sends was rare more.The prompt tone of user by listening hummer to send just can carry out alignment function intuitively.
In use, behind the preset time of interval, measuring each infrared receiver receives the intensity of infrared pulse signal and controls the infrared pulse signal intensity that each infrared transmitter is sent, can effectively adapt to the environmental factor that slowly changes as: rain, snow, mist, water vapor, sunlight, dirt accumulation, plant growth are blocked etc. the infrared pulse signal intensity are produced attenuation change, have not only avoided the generation of false alarm but also have made the intensity of the infrared pulse signal in the environment for use be unlikely to too high.Such as sunlight is important interference source to the infrared pulse signal, it is as follows to use method of the present invention that the interference of its generation is compensated process: the disturbing factor at sunny night is few relatively, at this moment the intensity of infrared pulse signal is minimum, as time passes, dawn, early morning, the morning, noon, the intensity of sunlight in afternoon and angle are gradually changing, infrared ray component in the sunlight is also gradually changing to the influence of infrared receiver, behind the preset time of interval (such as three minutes), measure each infrared receiver and receive the intensity of infrared pulse signal, and control the infrared pulse signal intensity that each infrared transmitter is sent, the compensation of carrying out corresponding enhancing or weakening in time, because intensity of sunlight and angle are to gradually change, the adjustment that the proper spacing time is carried out the infrared pulse signal intensity can make each infrared receiver receive that the intensity of infrared pulse signal is constant substantially in one day fully.
The independent of other environmental factors such as rain, snow, mist, water vapor, dirt accumulation, plant growth are blocked, accumulated snow is buried disturb, or the integrated interference of multiple environment factor under acting on simultaneously, equally also all be the process of a gradual change, be fit to adopt method of the present invention to solve.
For the discreteness of components and parts in the production run and technology, in like manner also be fit to adopt method of the present invention effectively to compensate, consistency of product is protected.
Break down when running into the components and parts that plant growth shelters from a certain infrared pulse signal beams or this infrared pulse signal beams correspondence fully, its pairing infrared receiver reflects that the intensity of receiving the infrared pulse signal is zero.At this moment operational failure screen method: shield for the infrared pulse light beam that produces fault, change by two infrared pulse light beams that are adjacent and participate in reporting to the police, in the hope of preventing the generation of false alarm.Simultaneously fault is pointed out, the scene prompting is carried out in flashing that sound that can send with hummer or luminotron send, also can be with the mode of data to subsequent product such as alarm host machine or other Intelligent treatment products prompting fault, to maintain easily.
When predetermined a plurality of or whole infrared receiver reflects that the intensity of receiving the infrared pulse signal is zero, illustrate that environmental baseline has exceeded the condition of work of product, at this moment product quits work and sends corresponding prompting, not only prevented the generation of false alarm, and the prompting user adopts the generation of additive method prevention alert.
The said microprocessor of the present invention comprises single-chip microcomputer, DSP, ARM etc.
