Security guards must know: Five minutes to understand access control system

Posted on

The use of access control system in life has been gradually broadened, and different types of channel equipment are required in different entrance and exit scenarios. For example, the three-roll gates and rotary gates of the stadiums, the pedestrian channels of campuses, enterprises, and high-end intelligent buildings. While effectively helping the staff to reduce their work pressure, they also ensured the safety of traffic.
Five advantages of access control system
1, easy to use. The existing access control personnel only need to undergo a simple training to get on the job. The channel gate maintenance personnel can find the fault by a few simple operations and can be quickly and easily eliminated.
2, advanced technology. Using the most popular wireless network management system, channel gates ensure that your management system will not lag behind for a decade.
3, low overall cost. From the point of view of installation, commissioning and wiring, adopting the TCP/IP transmission method can reduce a lot of investment. In addition, the construction period is short, the wire and labor costs are saved, and it is very easy to maintain. Therefore, the access control system is adopted. The cost is more advantageous.
4, use more. The channel gate management system uses a non-contact smart IC card, also known as a radio frequency card, successfully solves the problems of multiple use, confidentiality, no wear, and easy operation of the IC card, greatly improving the practicality of the system and enabling the implementation of one card. Multiple authorizations, channel gates can be used for other applications management. Such as attendance, consumption, parking management, patrolling, personnel.
5, easy expansion. Computers and intelligent management systems use wireless communication methods, and channel gates can freely expand the number of channels. That is, when the corresponding control system is installed, if it is necessary to increase the number of intelligent channel gates and elevator control devices, the hardware only needs to add corresponding channel gates, and the software can set new devices.
Three Influencing Factors of Entrance Barrier System
As an intelligent access control channel, its system is much more complicated than the traditional access control channel, and the factors affecting its function are naturally more. There are three main aspects to simply understanding:
1, design style
The high-end walkway needs to integrate product safety, modern and simple design concepts with the built environment and architectural style; the streamlined design is the main aspect of the lines, reflecting a simple and comfortable style. The use of glass and stainless steel is more suitable for materials. The stylish and transparent design is consistent with the intelligent building construction style; and the high-end walkway products have obvious differences in the processing of metal surfaces, including surface texture drawing processing, accuracy of bending angles, and between different components. The gap accuracy and other aspects.
2, the advanced nature of the movement
The advanced nature of the channel gate movement directly affects the long service life and operating conditions of the gate. Such as using the latest ARM control technology, using industrial-grade control processing method to complete a new product, with no noise during operation, smooth operation, no mechanical wear, long service life, etc., the entire product starts during operation It is very smooth when shutting down and it can quickly achieve brake closure.
3, intelligence
For example: The wing gate has an automatic reset function. After the gate is opened, the system will automatically cancel the user's permission for the passage of a specified time. The standard is automatically reset after 5 seconds. The intelligence of the wing gate is also reflected in the automatic opening of the channel after the power failure of the skeg, and the power is automatically closed. Wing gate also has a line self-check function, which can be discovered in time after a failure, which greatly protects the service life of the wing gate.
The advantages of the swing gate
1. There is no mechanical collision during the gate swing operation, and the noise is relatively small.
2. Compared with the triple roller gates, the bridge-type swing gates increase the pedestrian traffic detection Module, which can effectively detect the passing target and have strong anti-trailing capability.
3. The range of channel width is the largest among all the gates, generally between 550mm-1000mm. Some high-end products can be 1500mm, which is more suitable for the passage of pedestrians or bicycles carrying baggage, and can also be used for mobility inconvenience. Dedicated channel.
4. Appearance form plasticity is the strongest among all the gates. The material type of the blocker is rich, and the shape of the cabinet is also diversified. It is easy to design a very beautiful shape. Therefore, it is commonly used in office buildings, intelligent buildings, clubs and other high-end applications. .
The disadvantage of the swing gate
1, the technical requirements of the manufacturers are relatively high, if the design is not good will greatly reduce the reliability of the product, as well as reduce the ability to prevent personal injury against clips and collisions.
2, some models lack of waterproof and dustproof, only suitable for indoor, environmental adaptability is not strong with three roller gate.
3, the cost is higher, especially for some special custom models, such as increasing the width of the channel, the use of special material gate swing, the technical difficulty will increase accordingly.
4. Due to the restriction of the shape of the blockage body, the impact resistance of the swing gate is lower than that of the three-roll gate, and the illegal and rapid passage of the pendulum gate can easily damage the swing pendulum and the movement.
Wedge applications
It is suitable for occasions with relatively large requirements for passage width, including occasions where there are more pedestrians or bicycles carrying baggage, and special passages for people with reduced mobility. Also suitable for applications where high aesthetics are required. Such as community schools, attractions, ports, airports, stations and so on.
5, smart card: The system uses non-contact smart RF card, a successful solution to a card with multiple, confidential, no wear, easy operation and other issues, greatly improving the practicality of the system.
6, easy expansion: computer and swing gate using RS485 bus communication, source card system. After the corresponding control system is installed, the number of swing gates can be increased according to needs. The host system can perform back-end management and setting of newly added devices.
Wing Gate Benefits
The channel equipment has the characteristics of quick opening, barrier-free, safe use, low noise, convenient use and maintenance, and easy management of wing gates. It is suitable for high-grade residential areas, office buildings, and attractions, etc. It is the preferred product for pedestrians with high access frequency.
1) The wing gate has fault self-check and alarm prompt function, which is convenient for user maintenance and use;
2) The on-line programming of the operating status of the device can be performed through the built-in small button on the main control board;
3) anti-clamping function, when the swing arm is in the process of resetting, the wing gate will automatically bounce or automatically stop the motor within a specified time, and the intensity is very small. At the same time, an audible and visual alarm signal will be issued.
4) Sound and light alarm functions, including illegal intrusion alarms, anti-clamp alarms;
5) Anti-knocking function, when the wing gate does not receive the opening signal, the swing arm is automatically locked;
6) Telescopic arm synchronization function;
7) The wing gate has an automatic reset function. After the gate is opened, if the wing gate wholesale is not in use within the specified time, the system will automatically cancel the user's access permission. The standard is automatically reset after 5 seconds.
8) Power off can be freely adjusted normally open or normally closed to meet the requirements of different venues;
9) It can be connected with a variety of card reading devices, and the wing gate receives the relay switch signal;
10) One-way or two-way control of personnel in and out;
11) Wing gates can be remotely controlled and managed directly through a management computer.
