Description

The infrared remote sensing clock

Technical field

The utility model relates to a kind of electronic clock.

Background technology

Along with improving constantly of living standards of the people, there has been increasing family to use electronic clock, become the necessity in people's daily life, be widely used in various places.But, after using for a long time, find that there is following problem mostly in existing electronic clock: at first, usually hang in height in use, be not easy to the setting of time; Secondly, function is simple, mostly only has the function of displaying time, calendar and thermometric; At last, do not have memory function, in case need to readjust the time after the dead electricity.In addition, its major function of the digital electronic clock of selling in the market all is that the combination that depends on each functional module of digital circuit realizes, the chip portfolio of these digital clocks is connected all relatively more difficult with circuit, and also more complicated of the process of welding, and relative cost is higher.

Summary of the invention

In order to solve the technical matters of mentioning in the background technology, the utility model provides a kind of infrared remote sensing clock, this kind clock adopts single-chip microcomputer to consist of, simple in structure, low price, can realize infrared remote control, and can carry out burglar alarm and the warm early warning of limit, and can corresponding information be transmitted in real time by the GPRS module, can also guarantee simultaneously effective storage of original clock data after the dead electricity, have stronger practicality.

The technical solution of the utility model is: this kind infrared remote sensing clock, comprise main control chip, LCD MODULE and a DS1302 clock module that is made of the STC89C52RC single-chip microcomputer, its unique distinction is: described clock also comprises an infrared receiving module, DS18B20 temperature sensor, limits warm alarm module, burglar alarm module and GPRS module; Wherein, described burglar alarm module is made of after the type triode connects with being connected PH302 type infrared receiving tube, described infrared receiving module adopts the HS0038 receiving transducer, and described GPRS module adopts G200 pattern piece, and described limit temperature alarm module is made of after the type triode connects with being connected hummer; The signal output part of infrared receiving module, DS18B20 temperature sensor and burglar alarm module is connected to respectively the respective signal input end of described main control chip, and the teletransmission data controlling signal output terminal of described main control chip is connected to the corresponding data input end of described G200 module.

In addition, do not lose for data after guaranteeing dead electricity, described clock also comprises an EEPROM24CXX type storage chip, and the employing bidirectional traffic is connected between described storage chip and the main control chip that is made of the STC89C52RC single-chip microcomputer.

The utlity model has following beneficial effect: this clock selects the STC89C52RC that is produced by macrocrystalline science and technology as main control chip, can adopt normal domestic use telepilot emission infrared information to carry out setting and the modification of time at lower, liquid crystal LCD is as the clock of display part, very convenient operation.In addition, clock has partly adopted real-time timepiece chip DS1302, and it makes system timing more accurate.Simultaneously clock chip has adopted EEPROM24CXX type storage chip, the accuracy of retention time still after the power down, again setup times and date after need not to power up.Clock adopts digital temperature sensor DS18B20 to carry out the collection of environment temperature in addition, can carry out temperature by liquid crystal LCD shows, realize the fire alarm function by using the warm alarm module of limit, realize anti-theft alarm function by the infrared anti-theft alarm module, can corresponding information be sent on user's the mobile phone by the GPRS module simultaneously, make the user can monitor the middle situation of getting home.After possessing above-mentioned several functions, this kind clock also has characteristics, adopts exactly single-chip microcomputer to consist of simple in structure, low price.In sum, this kind infrared remote sensing clock not only can show normal clock information and temperature information, but also can realize the warning of temperature superelevation, burglar alarm and information transfer capability.Not only be fit to use at home, also can be applied in each large factory, mining area etc. simultaneously needs the in real time place of control, has stronger practicality.
