Intelligent door lock refers to locks which are different from traditional mechanical locks and are more intelligent in user identification, safety and management, mainly covering fingerprint locks, electronic coded locks, electronic induction locks, networking locks, remote control locks and other types. The biggest difference between smart lock and mechanical lock is that the former has electronic components such as fingerprint module, motor, processor and wireless connection module, while the latter does not; So smart locks need electricity to drive, while mechanical locks don’t. So what if the smart lock fingerprint lock is dead?
At present, the biggest power consumption of smart door locks lies in communication, because if the user’s mobile phone wants to keep connected with the smart lock at all times, the door lock must always be in a state of non-stop communication, so the power consumption is naturally accelerated. Of course, motor drive, standby, password input, screen and so on are also consuming electricity.
Since electric drive is needed, it involves the problem of power consumption. Therefore, many users are worried: What if the smart lock is out of power? Will it be rejected? Theoretically, there is a real risk of not being able to go home without electricity. However, as long as the smart lock meets the relevant national industry standards, it will basically not be rejected because the battery is dead.
For example, in GA374-2001
Electronic anti-theft lock "requires that the electronic lock must reserve a mechanical keyhole in case of emergency." Of course, with the smart lock, 90% of users choose not to bring their keys, because the keys are lost or forgotten. However, in order to prevent accidents, users are advised to reserve an emergency key in the office, car or bag.
In GA 701-2007
The General Technical Conditions for Fingerprint Anti-theft Locks puts forward strict requirements on the battery and power consumption of the smart lock: the working current of the battery should not be greater than 500Ma, and the working current in the dormant state should not be greater than 50 μ A. The battery capacity can ensure that the lock can be normally opened and closed for 3000 times without an under-voltage alarm indication, and when an under-voltage alarm indication appears, it should still be able to ensure the normal opening and closing operation for not less than 50 times.
As long as the smart lock meets the above standards, users don’t have to worry about the smart lock being shut out because it has no electricity. Therefore, when purchasing smart locks, users should first choose brands with high reputation and reputation. Secondly, you can’t be cheap, buy smart locks with prices lower than the industry level, and it is best to buy smart locks with prices around 3,000 yuan; Once again, it depends on whether the smart lock has passed the testing of the testing center of the Ministry of Public Security and what standards it implements.
At present, in addition to the fact that most smart locks have the function of early warning of battery power consumption, and all of them can remind users to replace the battery in time through SMS and voice, some enterprises have introduced smart locks that generate electricity by hand shaking in order to avoid users’ worries about the power consumption of smart locks. When the battery is exhausted, the smart locks can be charged by shaking the hands a few times, thus opening the locks smoothly. For example, Debaodun’s smart lock not only has a low battery reminder function, but also has a USB charging socket. When there is no electricity, you can use a USB cable to quickly charge the fingerprint lock through an external power supply such as a charging treasure to solve the urgent need.
Tips: Smart locks must check the battery regularly and replace the battery regularly. About 10 months. Check it out.
Every year, some customers’ fingerprint locks fail, all because the battery leakage corrodes the battery box, resulting in poor contact, and there is serious corrosion. The liquid penetrates into the circuit part through the battery box, and there are acidic substances such as ammonium chloride in the battery. The used battery is more acidic, which will corrode the zinc metal skin, and the shell skin will be corroded and damaged, and the liquid will flow out.
In a word: if you don’t want to be shut out because the smart lock is dead, you can’t choose a smart lock with low price that doesn’t meet the relevant national standards.
