The closing time of the wing gate is a core parameter for balancing traffic efficiency and safety protection, which needs to be comprehensively judged based on the two key stages of "delayed waiting" and "mechanical closure". The following provides clear answers from three aspects: industry standard scope, scenario adaptation logic, and technical influencing factors:

1、 Core conclusion: "Dual interval" standard for normal shutdown time

The closing process of the wing gate is divided into a delay waiting period (the duration of the gate wing remaining open after opening) and a mechanical closing period (the duration of the gate wing's movement from opening to locking), which together constitute the complete concept of "closing time":

Delay waiting period: The normal range is 1.5 seconds to 3 seconds, which is the industry default basic security threshold. This duration can match the average time it takes for ordinary adults to pass through a single channel gate (about 1.2 seconds), while also avoiding the risk of tailgating caused by waiting too long. For example, the Tarim University Gymnasium clearly prompts "Please pass quickly after the wing gate is opened", and the waiting time set is within this range, balancing the convenience of passage and management standards.

Mechanical closure period: The normal range is 0.8 seconds to 1.2 seconds, which is determined by the motor power and mechanical structure accuracy of the gate. High quality manufacturers such as Kangbao Security and Hikvision use servo motor drive, combined with a buffer closure design, which can ensure fast locking and anti tailgating, as well as avoid the risk of pinching, and the closure process is smooth without severe impact.

Overall, the normal time for the entire process from opening to closing the gate wing is 2.3 seconds to 4.2 seconds, which has been verified in most scenarios and has become the mainstream standard in the industry.

2、 Scene adaptation: dynamic adjustment logic for closing time

The traffic demand varies significantly in different scenarios, and the closing time of wing gates needs to be optimized accordingly. The following are adaptation solutions for typical scenarios:

High traffic scenarios (subway stations/airports): prioritize ensuring traffic efficiency, compress the delay waiting period to 1.5 seconds to 2 seconds, and control the mechanical closure period within 1 second. The wing gates deployed at Beijing Daxing International Airport have a full process closure time of about 2.5 seconds, coupled with a facial recognition response speed of 0.3 seconds, which can support a single channel traffic volume of more than 30 people per minute during peak hours, improving efficiency by more than three times compared to traditional gates.

Complex personnel scenarios (campus/old community): Emphasis is placed on safety and inclusiveness, with a delay waiting period extended to 2.5 to 3 seconds. During non peak hours, the wing gate of the student apartment at Chongqing University of Technology is set to close for about 4 seconds to meet the needs of students carrying luggage and the slow passage of the elderly, while avoiding security vulnerabilities through security supervision.

Security scenario (smart buildings/industrial parks): Balancing efficiency and security, usually set to 2.5 to 3.5 seconds. The wing gate of a certain technology park in Shenzhen is linked with the attendance system, with a delay waiting period of 2 seconds to ensure that employees can quickly pass and complete attendance. The mechanical closure period is 1 second to achieve instant locking, effectively preventing unauthorized personnel from following.

3、 Technology and Security: Key Factors Affecting Closure Time

The closing time of the wing gate is not fixed and its stability is influenced by multiple factors such as hardware configuration and environmental adaptation

Hardware performance: Servo motors respond 30% faster than stepper motors and close more accurately; The gate wing structure made of 304 stainless steel has high strength and can be closed at a faster speed without affecting its lifespan. This is also the core reason why the gate can maintain a stable closing speed in the salt spray environment along the coast of Ningde.

Security protection design: A gate with infrared anti pinch function, if an obstacle is detected in the passage area, will automatically extend the waiting period until the obstacle leaves before closing. This security mechanism may temporarily extend the closing time, but it falls within the scope of compliant design.

Environmental adaptability: In special environments such as salt spray and humidity, gates with a protection level of IP66 can avoid closing delays caused by mechanical jamming through anti-corrosion coatings, anti fogging lenses, and other designs. After 500 hours of salt spray testing, the closing time deviation can still be controlled within 0.2 seconds.

4、 Selection and Debugging: How to Ensure Compliance with Closing Times

Ordinary users or purchasers can determine whether the closing time of the wing brake is normal through the following methods:

On site testing: Use a stopwatch to record the entire process time from the opening of the brake wing to the closing and locking, and compare it with the standard range of 2.3 seconds to 4.2 seconds;

Function check: Test the infrared anti pinch function. When blocking the passage area, the gate wing should immediately stop closing and delay. After removing the obstruction, the closing process should be restored within 1 second;

Parameter confirmation: Manufacturers are required to provide adjustable ranges for delay waiting period and mechanical closure period. Regular products support customization of delay time from 0.5 seconds to 5 seconds to meet different scenario requirements.
