The anti-theft and rain-proof smart window is characterized in that the main control model is respectively connected with the humidity sensing model, the infrared sensing model, the motor drive model and the alarm model. Signals of rising humidity, theft situations and the like are detected by the humidity sensing model and the infrared sensing model and are sent to the main control model. The main control model logically processes triggering signals from different sensing models and controls the motor drive model to open the window or close the window, and starts the alarm model to alarm.

Description

The anti-theft rain-proof smart window

Technical field

The utility model relates to a kind of smart window, especially a kind of anti-theft rain-proof smart window.

Background technology

In today that living standards of the people improve gradually, intelligent control has progressively entered in the middle of people live, various smart machines constantly occur in household electrical appliance, in the new house finishing, the intelligentized design of motorized window is particularly important, therefore the smart window of the various functions such as antitheft, rainproof continues to bring out in the market, but most of smart window only have simple alarm sound, function singleness, the shortcoming such as expensive sent.

Summary of the invention

In view of above reason, the utility model provides a kind of anti-theft rain-proof smart window, the signal that receives infrared triggering that can be good, can accurately handle again the data of humidity sensor well, the opening and closing of good control smart window, because above chip cost is low, circuit is simple, reliable, realized finishing with low cost the intelligent equipment control requirement of high request.

The utility model provides a kind of anti-theft rain-proof smart window, comprise humidity sensor module, infrared sensing module, main control module, motor drive module, alarm module, it is characterized in that: main control module is connected with humidity sensor module, infrared sensing module, motor drive module, alarm module respectively.Detected the signals such as humidity rising and robber's feelings by humidity sensor module and infrared sensing module and send main control module, the main control module logical process is closed window according to the triggering signal control motor drive module from different induction modules or is windowed, and the startup alarm module is reported to the police.

The characteristics such as the beneficial effects of the utility model are, have both guaranteed user's property safety, also can embody the characteristics of hommization, and it all is more common adopting sensor, and circuit is simple, and cost is low, and is easy to maintenance have higher practical value.

The specific embodiment

The utility model provides a kind of anti-theft rain-proof smart window, comprise humidity sensor module 1, infrared sensing module 2, main control module 3, motor drive module 4, alarm module 5, it is characterized in that: main control module 3 is connected with humidity sensor module 1, infrared sensing module 2, motor drive module 4, alarm module 5 respectively.Detected the signals such as humidity rising and robber's feelings by humidity sensor module 1 and infrared sensing module 2 and send main control module 3, main control module 3 logical process are closed window according to the triggering signal control motor drive module 4 from different induction modules or are windowed, and startup alarm module 5 is reported to the police. [0008]Humidity sensor module 1 adopts a kind of novel Digital temperature ﹠ humidity sensor SHT11, this sensor has good operating stability, volume is little, the advantages such as power consumption is little, these benefit from the CMOsens TM technology of Sensirion company, and this technical description is for being integrated in chip internal with humidity sensing element, signal adjustment amplifying circuit, A/D change-over circuit, I2C bussing technique.In real work, the humidity resolving power of SHT11 has reached 14.Infrared sensing module 2 is comprised of a pair of infrared emission receiving tube, the outer appearnce of infrared transmitting tube is similar to the common stock light emitting diode, just launch invisible infrared light after the energising, if circuital current is excessive, can cause infrared transmitting tube luminous suddenly, then forever burn, so normal the use needs to add current-limiting resistance, in order to make infrared detection sensitiveer, adopt the pulse-triggered amplifying type at radiating portion, namely adopt a kind of Schmidt trigger and triode as infrared emission drive circuit, tranmitting frequency is about 38KHz.The infrared receiving tube outward appearance is identical with infrared transmitting tube, and just color is black, it should be noted that in addition infrared receiving tube in circuit be reversal connection in circuit, namely anode meets GND, negative electrode meets Vcc, the normal operation of guarantee circuit.Adopt the reflection mode in stealing the feelings detection, i.e. infrared transmitting tube emission infrared pulse light can not run into obstruction at ordinary times, but in case robber's feelings are arranged, reverberation can be detected at once, after infrared receiving tube receives reverberation, trigger at once main control module 3, start and report to the police.What main control module 3 adopted is the STC90C52RC series monolithic, it is a high speed, low-power consumption, the superpower jamproof single-chip microcomputer that macrocrystalline science and technology is released, 8051 single-chip microcomputers that instruction code is fully compatible traditional, 12 clocks/machine cycle and 6 clocks/machine cycle is selected arbitrarily, and inner integrated MAX810 Special reset circuit.The STC90C52RC series monolithic has the advantages that cost is low, performance is high, supports the ISP technology.Use the ISP technology can not need programmer, and direct burning user program on the custom system plate, it is very convenient to revise debugging.Utilize the IAP technology the special-purpose Flash of interior section can be used as EEPROM and use, the function of save data after realizing having a power failure, erasable number of times is more than 100000 times, can save external EEPROM(such as 93C46,24C02 etc.).And compatible with traditional 8051 SCM programs, hardware need not to change.Voltage 3.4V-6V, can't decipher, reduce the EMI(electromagnetic interference at superpower anti-interference, super low-power consumption).Motor drive module 4 adopts stepper motor 42BYGH4604, and ULN2003 receives the control signal from single-chip microcomputer as the operation drive circuit.Alarm module 5 is mainly by amplifier, light emitting diode, and protective resistance, and ring forms.Remind owner may have the offender to leap in through the window by acousto-optic.Because sensing chip is very little very transparent, also be difficult on the window being discovered so be installed in.
