Description
Technical field
The present invention relates to a kind of alarm method, particularly a kind of alarm method of discerning the indoor and outdoor target.
Background technology
Existing passive heat Infrared intrusion detector since price low, easy to use, by a large amount of uses in the safe antitheft field.The passive heat infrared alarm is by receiving the detection that human body 8-12 μ m thermal infrared wavelengths realize human body target.In general, the passive heat Infrared intrusion detector is regardless of stranger and household, will report to the police as long as detect 8-12 μ m thermal infrared signals.There is following problem at least in it: 1, wrong report easily: because 8-12 μ m thermal infrared signals do not exist only in human body, animal body, some household electrical appliance such as air-conditioning, sound wave stove etc. also can produce the signal of this wavelength when work, cause wrong report, therefore, when the passive heat Infrared intrusion detector is used in family, pay particular attention to setting angle; 2, be regardless of household and stranger: will report to the police as long as detect 8-12 μ m thermal infrared signals, therefore the household goes home in use, at first closes the switch of passive heat Infrared intrusion detector, can give the robber with opportunity at night.
In order to prevent that the problems referred to above from taking place, sell a kind of magnetic alarm now in a large number, it is by the magnetic device tongue tube of a magnetic device and induced field is installed on door, window, and tongue tube is during near magnetic field, dry-reed tube switch disconnects, alarm quits work, and realize reporting to the police in the position, when moving door, window, the magnetic field that magnetic device produces can reduce in a certain position, tongue tube in the circuit is connected, and alerting signal is sent in warning circuit work.Sort circuit is simpler, and is reliable, but wants to open the door or during window, must close a power switch of magnetic alarm in advance, because in time do not close alarm switch, no. and can trigger alarm during careful mobile window and send warning.
Summary of the invention
The purpose of this invention is to provide a kind of alarm method of discerning the indoor and outdoor target, when having only the layman to open door and window, alarm can not reported to the police, and the stranger swarms into outside window, and alarm will be reported to the police immediately.
The object of the present invention is achieved like this, a kind of alarm method of discerning the indoor and outdoor target, it is characterized in that: it comprises first detecting unit that is fixed on monitored space, second detecting unit and the control module of place of safety, at a detection window in the time, when first detecting unit at first detects monitoring objective, after control module obtained information, control module was with output alarm information; At a detection window in the time, when second detecting unit at first detects monitoring objective, after control module obtained information, control module is output alarm information and enter delay procedure not.
Described first detecting unit and second detecting unit can be the detected pyroelectricity informations of pyroelectricity detecting unit.
Described first detecting unit can be the reflective infrared information that active infrared detects; Second detecting unit is the pyroelectricity detecting unit, is used to detect rpyroelectric infrared information.
Described first detecting unit can be made of active infrared testing circuit and pyroelectricity testing circuit, and after the pyroelectricity testing circuit detected the pyroelectricity signal, the active infrared testing circuit was started working.
Described first detecting unit can be a magnetic switch, and second detecting unit is the pyroelectricity detecting unit, is used to detect rpyroelectric infrared information.
Principle of work of the present invention and characteristics are: the people is when indoor activity, when particularly going to balcony or windowsill, the second detecting unit very first time of place of safety detects the pyroelectricity signal, this shows, the pyroelectricity signal is that the guest by owner or owner causes that signal is safe, therefore, after control module obtains information, control module will be not output alarm information and enter delay procedure.During to balcony or windowsill, first detecting unit of monitored space detects signal to the people from outdoor, and this shows that signal is caused that by the stranger signal is unsafe, and therefore, after control module obtained information, control module was with direct output alarm information.
