随着社会科技和人们生活水平的提高,如何实现家庭防盗这一问题也变得尤其突出,传统的机械锁由于其构造简单,被撬的事件屡见不鲜,电子锁由于其保密性高,使用灵活性好,安全系数高,受到了广大用户的亲昵。
As society and technology to improve people's living standards, how to achieve domestic security in particular, this issue has become prominent, the traditional mechanical lock because of its simple structure, frequent incidents of prizing, electronic lock high because of their confidentiality, the use of flexibility good, high safety factor, the majority of users have been intimate.
红外电子密码锁是一种以高强度密码序列为基础,在单片机上实现的密码开关。它以红外光作为信息媒体,从而实现了遥控。该锁具有使用方便、操作简单、价格低廉等特点,给人们的生活带来了极大方便。特别适用于那些正常人体不宜接近的特殊场合,比如高辐射区、高传染区等。
Infrared electronic code lock is a sequence of high-intensity-based password in the Password to achieve single-chip switch. It is infrared light as an information media, in order to achieve the remote control. The lock has a user-friendly, simple operation, low cost, etc., to people's lives has brought great convenience. Particularly applicable to normal human body should not be close to those special occasions, such as high radiation areas, high-transmission areas.
本设计根据红外通信的原理,利用红外来传输,这便于对密码信息的保护。而且采用红外遥控相对于机械锁具有较高的优势。如红外线发射装置采用红外发光二极管,遥控发射器易于小型化且价格低廉;采用数字信号编码调制方式,不仅可以增加遥控功能,提高信号传输的抗干扰性,减少错误动作,而且功率消耗低;红外线不会向室外泄露,不会产生信号串扰;反应速度快、传输效率高、工作稳定可靠等。所以红外线遥控是目前使用最广泛的一种通信和遥控手段。本软件设计采用模块化设计思想,以使系统朝着分布式、小型化方向发展,增强系统的可扩展性和运行的稳定性。
The design of infrared communications in accordance with the principle to the use of infrared transmission, which facilitate the protection of the password information. But also vis-à-vis the use of infrared remote control has a higher mechanical advantage lock. Launchers such as the use of infrared light-emitting diode infrared, remote control transmitter is easy and inexpensive miniaturization; the use of digital signal modulation coding can not only increase the remote control function, to improve anti-interference signal transmission and reduce error action, and low power consumption; infra-red will not leak to the outside, does not produce the signal crosstalk; reaction speed, transmission efficiency, such as stable and reliable work. Therefore, infra-red remote control is one of the most widely used means of communication and remote control. The modular design of software design ideas to make the system distributed towards small and medium-sized and direction, enhance system scalability and stability.
