一种电子遥控智能门锁An electronic remote control intelligent door lock

技术领域technical field

本发明属于电子锁技术领域，特别涉及一种具有远程操控和GSM网络监测功能的电子遥控智能门锁。The invention belongs to the technical field of electronic locks, in particular to an electronic remote control intelligent door lock with remote control and GSM network monitoring functions.

背景技术Background technique

家居安全依然是当今人们最关注的事情，而家庭门锁是家居安全的首要问题。家庭门锁仍以传统的防盗门锁为主，这种门锁需要人们随身携带机械钥匙来开锁或上锁，钥匙容易丢失，且携带非常不便。目前的电子门锁主要有电子密码锁和指纹识别门锁，方便了用户的使用，但非法人员可以通过多次尝试的方法或者使用解码器来破解密码锁密码，进入家里而主人无从得知，同时指纹识别门锁只能通过用户本人指纹识别进行开锁，当别人需要开门而指纹用户不在现场时则非常麻烦。电子门锁还存在共同的问题是：门外开锁装置（密码键盘或指纹识别端口）一旦被外界环境损坏或人为破坏，电子门锁则无法打开，一些电子锁增加了备用开锁手段，但这无疑又降低了门锁的安全性。Home security is still the most concerned thing for people today, and home door locks are the primary issue of home security. Household door locks are still dominated by traditional anti-theft door locks. This kind of door lock requires people to carry a mechanical key to unlock or lock it. The key is easy to lose and is very inconvenient to carry. The current electronic door locks mainly include electronic combination locks and fingerprint identification door locks, which are convenient for users to use, but illegal personnel can crack the combination lock password through multiple attempts or use a decoder, and enter the home without the owner knowing. Simultaneously, the fingerprint identification door lock can only be unlocked by the user's own fingerprint identification, which is very troublesome when other people need to open the door and the fingerprint user is not on site. There is also a common problem with electronic door locks: once the external unlocking device (password keypad or fingerprint identification port) is damaged by the external environment or artificially destroyed, the electronic door lock cannot be opened. Some electronic locks have added a backup unlocking method, but this is undoubtedly Reduced the security of door lock again.
