Electric locks are commonly used equipment in access control systems, such as electric bolt locks (anode locks), electric locks (cathode locks), etc.
Electric lock refers to "electronic door lock". It is an electronic product that controls the circuit or chip work (access control system) through password input, thereby controlling the closing of the mechanical switch, and completing the task of unlocking and locking.

It has many types, simple circuit products, and chip-based products with higher cost performance. Nowadays, the widely used electronic code lock is realized by programming with the chip as the core.
1. After several generations of hard work, the electronic key code lock has a very concise working principle and can be imitated in a fully mechanical way.

2. In addition to imitating electronic locks, mechanical methods have their own unique advantages. Using these features will make the structure more concise, even out of electronic locks.

3. After the efforts of many people, there have been many solutions for the push-button mechanical code lock. And some people have done practical exploration on the principle or sketch, and selected some feasible solutions. If conditions are created to combine electronic technicians with mechanical technicians, the conversion will be faster.

4. The hardware manufacturing technology such as locks and tape recorder cores has been quite mature, creating conditions for production.
Commonly used electric locks:
1. Electric bolt lock (anode lock)
2. Electric lock (cathode lock)
3. Electromagnetic lock (magnetic lock)
Not commonly used electric locks
4. Electromechanical integrated lock
5. Push lever lock
6. Shear lock (combined magnetic lock and electric bolt lock)

Classification of electric locks:

According to function
1. Power-off and door-opening electric mortise lock
2. Power-off and closed-door electric mortise lock
3. Electric mortise lock with mechanical key
A, power-off unlock type
B, lockout type
4. Fully frameless glass door electric mortise lock
Power-off and close the door (power-on to unlock) (Fail-Secure)
Under normal closed door conditions, the lock body is not powered on, and the lock is in the "door locked" state. When the lock is powered on through an external control system (e.g. card reader, card reader), the internal body will act, and Complete the state of "opening the door", such as a cathode lock, a power-off lock type electric mortise lock.
Open the door when power is off (power on and lock) (Fail -Safe)
Under normal door closing conditions, the lock body is continuously energized, and the lock appears as a "door locked" state. When the lock is powered off via an external control system (e.g. card reader, card reader), the internal body will act, and Complete the state of "opening the door", such as magnetic lock, power-off unlock type electric bolt lock.
Comparison of power-off opening door and power-off closing door
Generally, it is suitable for various environments. "Power-off and unlocking": It is suitable for fire protection laws and regulations. Most fires are caused by wire escape. The heat at the fire site can melt the hardware door locks and prevent them from opening the door to escape. Many people were buried in the fire because the door lock could not be opened to escape. The advantage of opening the door after power failure is that once the power line is out of fire and the power is cut off, the smoke-proof door of the passage will be activated to prevent the spread of smoke, and people can also easily open the door. escape.
"Power off and close the door": It is suitable for vaults and other access control occasions with high property insurance. At this time, we can use the electronic mechanical lock and the cathode lock together with the lock core. Once the personnel are in danger, the rotary can still be used. Twist or key to open the door.
According to the working principle
According to the different working principles of electronically controlled door locks, they can be basically divided into:
1. Electronically controlled magnetic door lock: also known as magnetic lock, suitable for swing doors, which can be wooden doors, metal doors, and glass doors.
2. Electronically controlled locks: also known as cathode locks, suitable for single-door one-way swing doors, which can be wooden doors, metal doors, and used in conjunction with mechanical door locks
3. Electrically controlled bolt door locks, also called electric bolt locks, are suitable for wooden doors, fire doors, and glass doors
4. Electric control handle door locks: It is divided into hotel locks and smart locks.
Electric mortise lock selection
Electric mortise locks are generally used for glass doors. Depending on whether the glass door has a frame or no frame, it can be used with installation accessories such as door clips. One electric mortise lock can only control one door, and two-leaf glass doors need to be equipped with two electric mortise locks. For most access control projects, it is recommended to use an electric bolt lock that is opened when the power is turned off. When the access control system fails and other special circumstances, the power can be turned off to open the door, and the fire protection requirements for power off and open the door can be met. Some electric bolt locks have delay control and door sensor detection functions. The delay control function supports the delay of a certain time after the door is closed and then locks. For the glass door that is not easy to lock due to the poor performance of the floor spring, it can be adjusted by The delay lock time of the electric mortise lock has been improved.
There are two-core electric mortise locks and multi-core electric mortise locks on the market. After the two-core electric mortise lock is energized, the current directly drives the coil to produce electromagnetic effects. The electromagnetic force attracts the spring to control the iron core switch. It is easy to generate heat in use, and current fluctuations can also easily cause electric locks to malfunction; electric mortise locks with multiple wires generally have microchip control, which not only has functions such as lock status and door status detection, but also the operation of the electric lock is controlled by a single-chip microcomputer, with performance and reliability Better, it is recommended to use.
Magnetic lock selection
Fire doors, wooden doors, etc. can use magnetic locks. Magnetic locks have good stability and are not prone to performance degradation after long-term use. However, the safety of magnetic locks is not as good as electric mortise locks, and the locked state cannot be guaranteed when subjected to a large external force. . Magnetic locks with a holding force between 2000N and 4000N are more common and are also suitable for most places. Some brands have magnetic locks with a high holding force above 5000N, which are suitable for higher access control security requirements, but are not suitable for installing other types of electricity. The place of the lock is selected.
Magnetic locks can be divided into single-door magnetic locks and double-door magnetic locks. Only one double-door magnetic lock needs to be installed at the door points of the two doors. It should be noted that after installing the magnetic lock, the door can only be single-opened (inward or outward), and the magnetic lock is difficult to conceal and install, which may affect the aesthetics of the door.
Cathode lock selection
Cathode locks are generally used for single-leaf wooden doors. They are installed on the door side and used in conjunction with ball locks, handle locks and other mechanical locks. The door can be opened by swiping the card or using the mechanical lock key. It is generally used for room doors with low security requirements. . When choosing a cathode lock, pay attention to which standard the lock body specification adopts. Domestic door locks mainly have two kinds of American standard and European standard. Only the cathode lock and the mechanical lock adopt the same standard, can the size of the lock be guaranteed. The mechanical lock tongue is anastomosed to achieve the best lock state.
As an electric lock product supporting the access control and intercom of the intelligent building, it must be used in close coordination with the performance, demand and characteristics of the access control and intercom system during use. Generally, the following points must be paid attention to:
1. Wiring method
Many electric locks have many other connections besides the power interface cable. Among them, special attention should be paid to the lock status line and the door status line. The lock status line can provide lock closure information and is linked with the digital input interface of the access control system. Check the closed state of the lock in real time. The door status connection is a good substitute for the problem of installing a door magnet separately, which reduces the installation cost, improves the efficiency of the system, and better ensures the beauty of the building decoration.
2. Opening and closing delay settings
Many electric locks have a special delay setting jumper or dialing device, which can set the delay time of the electric lock, but most access control and intercom systems also have a delay setting function, so comprehensive consideration must be given when installing the electric lock Delay setting.
3. Electric lock power supply
There are many types of electric locks, the required current and voltage will be different, and the number of electric locks managed by each access control controller will be relatively large. At present, many low-end access control products will directly supply power to the electric locks. I think this approach is not It is worth recommending. First of all, the power configuration of the access controller is often configured according to the load of the controller itself. If the electric lock is driven again, it may cause the controller to work unstable or even be damaged; secondly, the distance between the electric lock and the access controller is also With uncertainty, long-distance power supply may also cause the electric lock to work abnormally; third, the frequent opening and closing of the electric lock during use may cause the current and voltage to be unstable. If the power is directly supplied by the controller, this current Voltage fluctuations may cause damage to the controller. This loss is unforgivable regardless of the value of the equipment or the requirements of the security level. It is recommended that no matter the size of the system, the electric lock power supply must be configured separately, and regardless of the control method of the access control and intercom system, it is recommended to use the relay isolation method for the electric lock opening and closing control to ensure the completeness between the electric lock current and the control host current. Isolated.
4. Additional equipment
Electric locks are best used in conjunction with additional equipment, especially door sensors. Especially in the access control system, the electric lock can only control the opening and closing of the door. If the electric lock does not have a feedback signal line, the opening and closing status of the door cannot be observed in the management software, so there is no feedback on the electric lock. When using a signal cable, it is best to use it with a door sensor.
The role of electric locks
The role of electric locks: Item safety and escape  The locks are based on safety applications, one is to help escape, and the other is to provide security (item safety). Public areas pay attention to escape, and administrative offices consider personnel escape and safety management. In both cases, access control systems and supporting mechanical locks are used.
Since the electric locks used in different occasions are different, it needs to be determined according to its application (installation position) and the type of door. Electric mortise locks are mainly used for glass doors, double-opening doors, etc. If a fire occurs, the door must be in an open state after a power failure; magnetic locks are mainly used for public passages. Generally, electric mortise locks and magnetic locks are only used for escape function applications, and item safety is rarely considered. At present, there are a few electric mortise locks on the market that provide key opening and security functions, that is, closing the door after power failure and opening with a key. The electromechanical integrated lock (electrically controlled mortise lock) can solve the contradiction between article safety and escape, not only can ensure the security management of the door, but also meet the needs of rapid fire escape. In the event of a fire, when the access control electronic system fails after the power failure, the indoor Personnel can operate the handle of the electromechanical integrated lock for emergency escape at any time. At present, buildings such as airports, subways, stations, stadiums, libraries, and grand theaters pay more and more attention to security and escape applications. The earlier and more extensive applications are in the fields of airports and subways, such as the Shenzhen subway, which adopts some of the main channels The electromechanical integrated lock (electrically controlled mortise lock), enters through the electronically controlled lock, and escapes with the aid of a mechanical lock in an emergency. Wooden doors generally use electric locks, that is, cathode locks.
In addition to the role of escape and security, electric locks are gradually developing in the direction of management to facilitate management. This is particularly prominent in some specialized office buildings, such as government office buildings, company/corporate office buildings, financial buildings, etc. These buildings have unified requirements for management, that is, they must be centralized at low cost. management. Centralized management office buildings generally have only one office unit, and all departments are in the same unit, that is, the general manager's office, various functional business offices, and employee offices are all in the same building. To achieve the best management efficiency and management status, the highest authority management unit All subordinate intelligent units in the entire building must have centralized and unified management authority, that is, the control of specific floors and each office lock point must have a unified management system to organize and implement, and the electronic intelligent door lock management system came into being .
Technology is developing steadily
Many industry insiders said in interviews that currently, the lock technology on the market does not have many bright spots, but there are big brands, some big lock brands have a history of hundreds of years, and their products are relatively mature in terms of technology and details. The advantage of the separation of internal and external control is that because the door can always be unlocked and exited with one action, it relieves the worries of escape from the door. Users can safely choose the access control method outside the door according to their needs, which effectively solves the contradiction between security and escape; and the external clutch The handle function can make the outer door handle idling in the locked state without driving the lock tongue, which greatly enhances its anti-vandal function. The mechanical magnetic lock has a backlight warning function and a mechanical and magnetic symbiosis function. It adopts the backlight concept, the light eye is changed from the previous "dot" shape to "face" shape, green means the door is closed, red means the door is not closed, the guards can judge according to the light color of the lock when they are far away Whether the lock is locked properly; The function of mechanical and magnetic symbiosis (mechanism and magnet) is based on the principle of electromechanical symbiosis. The most important thing is to convert electrical energy into magnetic energy, and then magnetic energy into mechanical energy, which will work together to enhance tension.

At the same time, electric locks have also been improved in terms of material selection and durability. If it is made of stainless steel, the bolt structure is changed from round to square, the contact surface between the bolt and the lock is enlarged, and the warning function can be optionally provided. All of these have improved the product quality of electric locks as a whole.
