Channel gate application scope analysis <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> Wing gate in its beautiful shape, due to give a sense of seriousness, it is often used in government units Swing gates can be divided into two types, one is a normal swing gate (ie, front and rear swing gates), and the other is a swing gate.
Compared to the wide sense of the gates of the wing gates, the swing gates are concise and yet generous. The general swing gate can be used as a double pendulum, and can also be used as a single speed door. It has three types of operation - single pendulum, double pendulum host, and double pendulum slave. It is suitable for senior office buildings or government departments. Wait. The lower gate is often used in high-level office buildings, government departments, or airports.
The three-roll gate adopts the method of rotating brake rods and is commonly used in the management of pedestrian passages and automatic ticket sales, such as government agencies, factory companies, smart buildings, residential quarters, scenic venues, universities, kindergartens, railway stations, and leisure and entertainment venues.
Barrier-free access gates do not have gates, and pass through infrared induction methods to check passersby to reach obstacle-free brushing cards or to directly calculate the flow of people. The channel gate device can ensure 35 people in one minute, which is suitable for applications where the traffic efficiency and overall beauty are high.
The arm-barrier is concise and beautiful, and the flexible-length arm can be used to regulate channel and wide-channel applications. It has an ultra-thin body and saves space for installation. It can be widely used in advanced commercial establishments, exhibition centers, noble communities, and classic ticket gates. Public transportation and other occasions.
The main difference between the purchase points <br> <br> channel gate 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, we need to consider many Selection the elements of.
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 point. Multiple detection points form an effective identification 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 of the human walkway door wing. High-end walkway products generally do not adopt the traditional point-to-point infrared radiation detection method. Instead, a led high-density matrix infrared detection light curtain is used to determine the validity of location, state, traffic direction and authorization verification of pedestrians within the channel, and calculation 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 legal authorization. After the authorized person has passed the channel, he has 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 an audible alarm and indicator light alarm. When the 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. Enter, because in designing, we consider the safety of the person, if the door leaf closes and will hurt people, so the door leaf will not be closed at this moment, but the channel equipment will have 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 web-based remote channel monitoring and management system can flexibly manage and monitor the pedestrian lanes at any time, anywhere, regardless of the physical location.
Wide application range of channel gate has three major considerations
Current channel gate equipment includes conventional wing gates, swing gates and three-roll gates. With the development of skills, barrier-free access gates and arm-type brakes gradually emerged. Channel gate devices with different appearances will bring different experiences to different applications (such as high-end office buildings, airports, government departments, factories, BRT, subways, high-speed railways, etc.).
