Due to the rapid development of modern technology, some electronic intelligent products have gradually entered our lives, just like the password lock we are talking about today, it is a type of lock, but it uses a series of numbers or symbols when opening.Password lock is a relatively high -level lock. It has the advantages of fast operation, simple to modify the password, and can be unlocked with only 0-9 numbers.So, what should we do when we forget our password when using the password?What is the working principle of the password lock?Lets take a look today.
What to do if the password lock forgets the password
First use a strong light flashlight to look at a gear of the password lock, and slowly pull the gear at the same time.At this time, if you look closely, you will find that when you turn to a certain position, there will be a gap below the gear. This gap will generally be a little bit to the left.Sure enough, a small gap appeared under the gear when turning to Number 6.The second and third gear numbers are also "6".
To do this, you have succeeded in mostly, and you must remember a formula.According to experts, the number corresponding to the gap is not a password. Based on these numbers, you need to "add 3", "plus 8" or "minus 5". When two digits appear, one digitsThe law.The reporter tried the number "6", "6", and "6" corresponding to the luggage gap, and "added 3" to get "9", "9", "9".Successfully opened.
Types of password locks
Now more electronic locks are centered on the 51 series single -chip microcomputer (AT89051), with the corresponding hardware circuit, and the coding settings, storage, recognition and manifestation, drive electromagnetic actuters and detect its driving current value, accept the sensor sent by the sensorAlarm signal, sending data and other functions.
Single -chip machine accepts the code that is keying and compares with the code stored in EEPROM. If the code is correct, the electromagnetic actuator is unlocked; if the code is incorrect, it promise to enter the codes from the beginning, and enter up to three times; if it is three times, it will beIncorrectly, the single -chip microcomputer reported to the intelligent monitor by the communication line.The single -chip machine sends each unlocking operation and the driving current value of the electromagnetic actuator at this moment as the condition information to the intelligent monitor. Together, the alarm information from the sensor interface is also sent to the intelligent monitor as the basis for intelligent analysis.
Radio electronic lock.Non -door -lock electronic locks can be used in the field of logistics transportation, warehousing, fresh milk transport vehicles, banknote transport vehicles, refrigerated vehicles, drug transportation, tobacco transportation, etc.If you use it for banknotes, the special car peoples Kou Gai and the door of the warehouse to ensure the safety of the transportation or detention goods, and avoid theft operation.The electronic lock uses a mechanical lock body to connect with the related skills of the Internet of Things, and the lock body has a built -in wireless receiving and receiving module. When the lock is turned on and off, the wireless receiving and receiving module will be transmitted to the monitoring host for long -distance lock signal.If the unlocking signal accepted by the monitoring host appears in an abnormal time, the signal is judged as stolen and priced signals. The monitoring host immediately reports alarm information so that the relevant personnel can deal with it in time to avoid financial loss.
What are the types of password locks?
I. Dial -dial -type mechanical password lock characteristics Dial -dial password lock similar to the dial of old telephone. Starting from the starting point of the dial, turn the dial dial to a digital clockwise, and then return to the starting point.EssenceRepeat this until the last password is entered, and then the dial can be unlocked by turning the dial from the starting point.While the unlocking, the internal reset has been reset, so after the dial is returned to the starting point lock, you must re -enter the password to unlock. There is no need to consider the internal reset problem.Advantages: 1. Disk -dial password locks generally have six -digit passwords, and more than 2.98 million sets of passwords can be transformed at will with high confidentiality.In addition, the number of passwords and passwords can be redesigned according to the needs of the user.You can also increase the alarm interface for the user; 2. Without a key, no power, no battery, safe and reliable; 3. All mechanical structure, can withstand a very harsh external environment and wide use range.Disadvantages: Some password hanging locks can tighten the lock, and then rotate the turntable until it cannot be moved again, so that the password can be found.There are also specific relationships between the numbers of the turntable password lock, which reduces the possibility of the combination of the password.The cheap password hanging lock can be opened with special lining, without the need to use a password dial -dial -dial password lock, which is generally used in safe, safe, file cabinets, etc.However, the dial -dial password lock is relatively rare on the home door. The reason may be that the operation is relatively complicated and the operating keyboard password lock is as a substitute.Just like the keyboard -type phone replace the dial -dial -type phone.Second, keyboard password lock introduction From the current technical level and market recognition, the most widely used is the keyboard electronic password lock.The keyboard -type electronic password is entered on the keyboard, which is similar to calling, so it is easy to master.Its prominent advantage is that the "password" is the number or characters recorded in the mind of the authorized person. It is accurate and reliable and will not be lost (except forgotten), and it is difficult to be stolen (unless it is leaked by yourself).If the password is leaked, the password locks the consequences.The important feature of the anti -leakage function of the password is therefore ensured that the security of the password lock is the most important thing to ensure the security of the password.At present, many password locks have "arbitrarily set passwords" technology, "automatic change password" technology, "keyboard disorder display" technology, "multiple password settings" technology, etc., to ensure that the password is not leaked.Although the new electronic anti -theft locks are endless, keyboard electronic password anti -theft locks are still in the mainstream market, and they are often used as auxiliary input methods for other types of anti -theft locks.
