Problems like access control, how does this kind of access control open?

If an access control machine is not an all-in-one machine, it can be connected to 2 or 4 or more, this depends on what type of control machine you choose, if you use an all-in-one machine, it is to swipe the card and press the fingerprint and communicate on a machine, half of this machine is more suitable for up to 2, because according to the problem of working voltage, the more locks, the power supply will be unstable, resulting in abnormal use of locks.

Now the fingerprint machine has a card reader function, that is, the card and fingerprint are read on a machine, and there is also a card reader input, the relationship between the exit switch and the card reader is or, if you have a card reader in the door, then don't use the exit button, vice versa.

Factory settings can definitely be set, if the access control machine with LED screen and keyboard, it should be directly operated on the machine, and the software is linked to the device can also be operated.

In theory, the access control host can be connected to n locks, but there is no need to connect so much, it is impossible to swipe the card in one place, and the door in other places is also open! Some fingerprint machines with card readers do not need to connect the card reader, the door switch is wanted, used to open the door in the room, the factory settings can definitely be restored, you did not find the corresponding method, it is recommended to consult your ** business, the factory reset settings of each host are different.

The access control system is mainly composed of a controller, a card reader, a power supply, an electric lock, a door button, etc.

The electric lock is generally determined by the number of doors, the door area is double-opened with two locks, and the access control controller is divided into a single door, two doors, four door control, and the access controller generally adopts the door swiping card, the door switch mode, and can also use the two-way card swiping (the door switch is replaced by a card reader).

If the fingerprint machine is an all-in-one machine (integrated control card reader), it can directly control the door opening, and there is no need to install a card reader, but it is still necessary to go out of the door button inside, unless a fingerprint machine is added inside, but if the fingerprint machine is only a card reader, it can only replace the original card reader, and the control device cannot be missing.

I don't know if you are **, if it is Jinan, I can let the company's technology provide you with some support, I just know a simple point, the access control host can be with four magnetic locks, electric plug locks can be brought with eight, as long as the voltage is enough to be more, at the same time the fingerprint machine needs to be out of the switch, do not use the card reader, if necessary, also add a reading head!

Meaning:Dedicated channel isThere's no way around itAccess cardUnlocked.

The impassable access control cannot be avoided means: the road section is restricted, there is an access control, and it cannot be passed. Impassable access control cannot be avoided" is the map of Gaode.

The traffic restriction function can be set by setting the license plate through the AutoNavi map to avoid the traffic restriction.

Dedicated channel (pinyin: zhuān yòng tōng dào). It refers to a channel specially established for a certain type of people or things, and provides convenience for the handling of such groups of people or things.

Mostly refers to the road or macro oak information communication channel, and is now also used for specific channels on the network.

Restricted lane refers to a special road for a specific vehicle or specific person, such as a special passage for the disabled, a special passage for fire trucks, a special passage for buses, etc. In addition, in some terms, it means a channel, such as a special channel for the exchange of money.

Ministry of Transport.

said that starting from this year's National Day Minmin holiday, the expressway will be exempted from passenger car tolls. The Ministry of Transport requires that toll stations with large traffic flow should set up special free passages for small passenger cars on major holidays to avoid mixed passage of toll vehicles and free vehicles.

Try adding one or two more zeros to the front, such as 001802 or 01802

As long as the mobile phone that supports the NFC function can be turned into an access control card, you will never be afraid to forget the access control when you go out!

Add 0 in front to try, the best way is to ask, the residents inside, the code inside can be changed, so each access control is not necessarily the same.

Access control refers to the prohibition authority of the "door", which is the vigilance and prevention of the "door". The "door" or key here, in a broad sense, includes all kinds of passages that can be passed, including doors for people to pass, doors for vehicles to pass, etc. Therefore, the door shirt is clever to include vehicle access control.

In the application of parking lot management, vehicle access control is an important means of vehicle management.

The entrance and exit access control security management system is a new modern security management system, which integrates microcomputer automatic identification technology and modern security management measures.

It involves many new technologies such as electronics, mechanics, optics, computer technology, biotechnology, etc. It is an effective measure to solve the entrance and exit of important departments to achieve security prevention management.

It is suitable for all kinds of confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, office rooms, intelligent communities, and factory yards.

Access control: refers to the prohibition of the "door", which is the right to "door"."Precautions.

The access control system is in the field of intelligent buildings, which means access control system, abbreviated as ACS. Refers to the prohibition of the "door" and is the right to the "door.""Precautions. The "door" here, in a broad sense, includes all kinds of passages that can be passed, including doors for people to pass, doors for vehicles to pass, etc.

Therefore, access control includes vehicle access control. In the application of parking lot management, vehicle access control is an important means of vehicle management, not for the purpose of collecting parking fees, mainly to manage vehicle access authority.

Analysis: What is access control.

Access control, also known as access management and control systemIt is a digital management system for the entry and exit of managersCommon access control systems are:

Password access control system, contactless IC card (inductive IC card) access control system, fingerprint iris palm biometric access control system, etcPassword access control system due to its own weak security and poor convenience has been facing elimination, biometric access control system high security, but high cost, due to the rejection rate and storage capacity and other application bottlenecks and has not been widely recognized by the market

Now the most popular and common in the world is the contactless IC card access control systemContactless IC cards have become the mainstream of access control systems due to their high security, best convenience and cost performance.

The following is the contactless IC card access control system, and referred to as the access control system

Components of an access control system.

The access control system consists of an access controller, a card reader, a door button, a communication hub, a proximity card, and a management software

Remarks: The above are the components of a networked access control system

Some access control all-in-one machines integrate the reader and controller together, so that because the control part is exposed, the security will be reduced, and the cost will be lower

Some require strict management of access control systems, will replace the exit button with another card reader, that is, two-way card reading access control system, so that not only can manage the authority of the person who enters, but also can manage the authority of the person who goes out, and record its entry and exit recordsA higher level of securityThere are also access control system card readers with password keypad function, when entering not only requires the card to meet the identity of the pass, but also must enter the relevant password, so as to ensure that even if the card is picked up can not enter

Biometric access control system refers to the access control system that replaces the card reader with a fingerprint device, iris device, palm meter, etc

The communication hub has two functions, to increase the transmission distance from the controller to the computer, and to network numerous control units

1. Situation one, this card has been deleted by the access controller, and you can add it again.

In the second case, if it is an electric plug lock, the lock cylinder may be stuck by the aluminum clip.

In the third case, the signal line of the access control controller is not connected, or it has been dropped.

Second, whether a single card does not open the door or all the cards do not open the door, whether the device responds when swiping the card, if the pin Li Lu does not respond, then check whether the card is damaged; If other card swiping devices also do not respond, then check whether the read head of the device is damaged; If a single card does not open the door, check whether the card has the permission to open the door.

All cards do not open the door** It is also to check the access control authority first, including the time period of opening the door, try whether the door can be opened through the software, check whether the door switch can open the door normally, and check the access control deficit plate; If you want to use the stand-alone version of the device, try to add the card again, check the door switch, check the power supply, and check the access control device;

Third, the card can not be opened, it is likely that the card is not authorized, if other cards can not be opened, there are two possibilities, one is the line problem, that is, the card controller to open the door signal, but the line is not through, the other is the controller itself problem, there is no door opening signal, you can judge so, when swiping the card, look at the lock above, there are red lights and green lights, the green light is the signal light to open the door, the red light is not responding, if it is possible, it is best to check the controller, when swiping the card, If it is an authorization card, the relay of the controller will ring when swiping the card.

Access control is also called access management system, that is, through digital circuits, the entry and exit of personnel are controlled, and the entry personnel must have designated sensors or passwords and other credentials to enter.

When handling the access control card, the family information must be stored in the access control card, so we must pay special attention to the custody can not be lost, to avoid being picked up by others after copying the information in the card, being used, resulting in property loss, after the loss must be reported as soon as possible.

Access Card Type:

1. ID cards, also known as identification cards, are identified by induction, have a separate card number, and cannot be changed, and can automatically identify the card number, which is no different from ordinary cards. The safety factor is not high, and it is easy to be copied and used by criminals.

2. IC access control, the upgraded version of the ID access control card, is an integrated circuit card, a lot of information can be directly stored in the card, the security and confidentiality are better, and the password can also be designed, so it is not easy to be copied, if you want to modify or delete the information, you must pass the password or pass the password.

3. CPU access control card is a kind of smart card, the card has a CPU with its own processor, and the storage hall is closed with data, which is also a kind of IC card, but the security performance is higher than that of IC card.
