Security issues:
The lock has always been a kind of device in people’s mind to ensure the safety of property, but so far, people have not created a lock that can completely guarantee the safety of property. Unattended or regulatory environment, only mechanical locks can prevent a “gentleman” and can not prevent “bad people” stealing with a key to open (due to general mechanical key tooth flower that only a few thousand tens of thousands of codes, easy to copy) Or be destroyed. And electronic locks can not only prevent the “gentleman”, but also prevent the “little man” from stealing the key to open (because the password of the general electronic key is as small as several million; as many as hundreds of billions, it is extremely difficult to copy), but of course, What needs to be understood is that so far, there is no lock that can prevent powerful damage.
Power supply problem
1. Generally, the lock body of electronic lock must be powered by AC mains or battery to work.
2. At present, some electronic locks also use dry battery power supply solutions: dry batteries work in a cabinet with a higher ambient temperature, and their life is shortened and uncertain. When the ambient wet higher degree, due to continuous use (low power consumption standby state) of the battery, the battery and battery spring contacts easily produce an electrochemical reaction, lead to corrosion of the plating cell and shrapnel, and even contact failure, failure of the electronic lock. As we all know, a large number of discarded dry batteries and lead-acid batteries will cause damage to the environment.
3. In short, in addition to the above common drawbacks of electronic locks with power supply in the lock, the direct consequence is: in order to ensure its reliability, it is necessary to increase the routine maintenance and maintenance work in the later period, which leads to the increase of manpower and material resources. The difficulty of management work. One of the major advantages of passive electronic locks is that there is no need for power in the lock (the working power is on a small digital key with extremely low power consumption), not only has the multi-function and high performance of electronic locks, but also has the same easy installation as mechanical locks. , No routine maintenance, high reliability and other features.
Compared with ordinary electronic lock cylinders , passive electronic locks have rich functions. Users and managers can issue, repeal, and change unlocking keys by themselves; one key can be set to open multiple locks with different passwords; different unlocking permissions can be set for keys to To achieve the purpose of hierarchical unlocking; multiple unlocking information can be recorded for later inquiries. Almost all the practical functions of ordinary electronic locks can be realized by passive electronic locks. Therefore, more people will prefer to choose passive electronic lock core products.
