石家庄铁道大学四方学院毕业设计 家用红外现场报警的设计 Household Infrared Alarm at the Scene Design 摘　要 红外线波长为0.76～1.5Abstract Infrared wavelength of 0.76 to 1.5microns, is one of the many invisible light one, has a strong penetrating ability, also has the nature of concealment, just because of this, infrared alarm system has very wide application.With the improvement of peoples lives, safety on peoples life is more important, so the infrared alarm to improve peoples quality of life has important significance. The design is based on SCM and infrared module alarm design, system software design and hardware implementation are described in detail.This design includes STC89C52 MCU core control element, 2401 remote control module, the infrared module, alarm is composed of four parts.The alarm when the transmitter emits infrared,under normal circumstances,the receiving end receives the infrared,alarm no alarm,when someone, infrared shielding was launched, the receiving end receives the reflected infrared ray, the driver buzzer alarm.When the family shelter through infrared, pressing a remote control button to a transmitting terminal stop emitting infrared, this time without warning, thus realizing the household infrared alarm system design. Household infrared alarm widely applies in the market, family, etc This design is the operation is stable, and the hardware circuit is simple, and has practical value.
