With the progress of the times, safety gates are no longer limited to the use of ticket inspections at airports and subways, but are more frequently used in high-end office buildings, libraries, theaters, factories, convention centers, stadiums, and tourist attractions. A fast, smooth and efficient dual-controllable channel with a competitive, high-quality, safe traffic control system. The efficient door wing sliding system and brushed stainless steel surface material create a beautiful appearance that satisfies the practical and aesthetic needs of most interior architectural designs. The unique design makes it suitable for a variety of channel monitoring environments, allowing single-channel and multi-channel installations to work with most access control systems.
First, the channel gate channel gate <br> classification <br> kind of diverse, it can be divided into:
1. Retractable speed gate (wing gate), which is characterized by its fast, smooth single or bidirectional control access;
2, swing gate, it is a kind of high safety protection level of pedestrian access control equipment;
3, optical doors, mainly used to solve the influx of population flow and identity and design of monitoring and access control equipment;
4. Three-roll gates, which are restricted-row access control devices that specifically address access control and population flow;
5. The revolving door, mainly designed for high-level security requirements of the two-way fast-track control equipment, can be used for unmanned channel management;
6, Pingkaimen, mainly for the channel called a spacious place designed to limit the level of access control equipment.
Second, the general characteristics of the channel gate features 1, anti-trailing function: the channel in the infrared light zone detection area can be used to adjust the switch state according to customer accuracy requirements, adapt to different needs of the application of the light band to avoid the point of infrared detectors are easily contaminated, The shortcomings that affect the reliability of judgment can effectively determine the trailing person of an unread card. When the system determines that a tail occurs, the system will respond based on the location of the active cardholder returned by the infrared detector. After the door opening signal is issued, there are still some abnormal use that will trigger the alarm system.
2. Irregular usage: (1) When the door is closed, the reversed pedestrian enters the pedestrian after the authorized door-opening signal is sent out. Before passing the first safe photoelectric detection zone, if the reverse detection zone detects that someone enters, When the person does not leave, the buzzer will always give an alarm and the door will remain closed. The “aging†function does not calculate the time interval. (2) Reverse entry when the door is opened. After the door is opened, if an unauthorized pedestrian enters the door detection area in the reverse direction, the door is closed immediately. As long as the first protection detection belt detects the presence of someone, “aging†The function does not calculate the time at this time. When the person leaves the second detection zone, the door resumes normal work. (3) When the pedestrian left, the reversed intruder passed the second security detection zone. Before the door returned to the basic state, the second security detection zone again detected that there was no entry, and the alarm system issued an alarm. However, as long as someone is still detected in the protection zone, the door will not close. (4) The tail body detects the pedestrian from the first detector to the last detector that left the first security detection zone. The time gap is about 0.25 seconds. After the pedestrian leaves the first security detection zone, the reader signals. In the absence of an open door, a pedestrian (trailer) was detected in the first detection area. The alarm sounded and the door remained open. (5) After the normal trailing pedestrian leaves the protection detection area, the first security detection area detects that an unauthorized person has entered and the door is closed immediately. The alarm sounds.
Third, the main difference between the purchase channel gate points <br> <br> manways different products in addition to the door motion, different grades of materials in the product process, differences motor drive and control system is relatively large, consider Selection Many factors.
1. Personnel safety: High-security personnel traffic protection is mainly to understand the mechanisms of the pedestrian passage products in the trajectory and behavior identification of personnel, the anti-pinch mechanism of illegally entered personnel, and the emergency response processing in emergency situations. These aspects are also The basis for guaranteeing the high security of pedestrian access products.
Pedestrian channel products have a certain number of radio detection points at different positions inside the channel. When a person passes through, the limbs will cover the detection points. Multiple detection points form an effective recognition of the movement trajectory and behavior of the passing person. The pedestrian passage is based on high The tracked traffic logic detection algorithm running in the central controller of the performance ARM9 technology realizes high-efficiency logic judgment and drives the response action of the pedestrian passage door wing. The high-end pedestrian passage product generally does not adopt the traditional point-to-point infrared radiation detection method. Instead, LED high-density matrix infrared detection light curtains are used to determine the location, status, traffic direction and authorization verification effectiveness of pedestrians in the channel, and calculations and analysis are performed to make corresponding judgments. Follow-up traffic detection methods to protect pedestrian safety. The greater the number of sensor points, the better the security and functionality, but at the same time the higher the complexity of the logic algorithm. In similar products, high-end brand manufacturers use up to 16 pairs, and some even up to 20 pairs, the minimum monitoring distance can reach 12 centimeters, while most of the domestic low-end manufacturers use mostly in about 10 pairs, including Only 4 pairs of products are used.
The product's anti-pinch protection function is realized through the door unit and the traffic detection system. During the pedestrian's access, any one of the protection sensors is triggered and the channel will be in an open state. When the access door is closed and the object is blocked, the door leaf will immediately become free, thus preventing the pinching of the passing personnel and ensuring the personal safety of our pedestrians.
Emergency handling in the event of an emergency. Pedestrian equipment should be set aside for fire signals. When a fire signal warning or power failure is received, the doors will be automatically unlocked and become free, forming a barrier-free emergency evacuation crowd. No accidental casualties will occur. This emergency function can also be used to set and switch the channel operating status through the remote channel monitoring and management system.
2. Security and security: The high-level security protection level is mainly to understand the detection, prevention, and alarm handling mechanisms of the pedestrian channel products against illegal entry personnel and to prevent the occurrence of people's trailing phenomenon. The trailing detection function includes two detection methods, one is the trailing entry detection and the other is the reverse entrance detection.
The trailing behavior in the trailing detection function refers to the deception that the person attempts to pass without being legally authorized. When authorized personnel pass through the channel, they have left the safe area of ​​the channel. At this time, the access door leaf will automatically close, but at the same time There are unauthorised personnel attempting to follow through the passageway, and the door leaf will block pedestrians from passing through. At this time, the channel will issue audible alarms and indicator lights; when authorized personnel pass through the channel, they have not left the safe area of ​​the channel. At this time, the trailing person tries to trail. Into the design, we consider the safety of the person. If the door leaf is closed, it will hurt people, so the door leaf will not be closed at this time, but the channel equipment will have an audible alarm and indicator light alarm to prompt us The abnormal situation occurred in the staff, which reflected the security protection capabilities of the pedestrian passage and the ability to protect personal safety.
3, performance and safety: reliable and lasting operating capability is mainly to understand the people's walkway product door unit components of the motor technology, fault-free operation time, personnel per unit time pass rate, the system maintainability and so on.
In terms of guaranteeing reliability, it is an important door unit system. The door unit drive motor of the high-end walkway product adopts brushless DC servo drive technology. At present, servo drive technology is the most advanced motor technology. The vast majority of products in the market use ordinary DC motors. The advantage of using brushless servo motors is that they have fast operation speed, no mechanical losses, accurate positioning, and stable operation. The operation time of the door unit using the brushless DC servo drive technology is less than 0.8 seconds, which guarantees a high pass rate of 60 people per minute. The high-end walkway products generally have a trouble-free running time of no less than 3 million times.
In terms of maintainability of the system, high-end walkway products are generally equipped with a remote channel monitoring and management system. Through the TCP/IP network, the real-time monitoring and operation management of the running status of the pedestrian walkway can be realized remotely. The mid-to-low-end products are usually switched between manual mode by using the jumper on the control board inside the walkway, or by physically controlling the switch panel. In contrast, the remote channel monitoring and management system based on the WEB mode can be managed and monitored flexibly on the pedestrian path at anytime and anywhere without being limited by the physical location.
