Application analysis of cutting-edge rotary turnstiles in a large-scale event

一,The capacity to change technological features to fit different activity scenarios
1. High throughput and speed control that changes throughout time
The throughput of traditional turnstiles is about 30 to 40 people per minute. However, new products have increased the efficiency of the single channel throughput to 60 people per minute by improving the movement structure and control algorithm. For instance, one type of turnstile uses hydraulic shock absorbers and electromagnetic locking mechanisms, along with a PID speed regulation algorithm, to keep the revolving speed and passenger flow density in sync in real time. During peak passenger flow times at the music festival's main entry test, the system was able to handle 72 passengers per minute, which is 80% more than previous equipment.
2. Multimodal authentication and stopping someone from following you
Because of the complicated identities of people at big events, the turnstile has four ways to check: QR code, ID card, facial recognition, and NFC. For example, the turnstile in a certain scenic area uses 3D structured light technology for face recognition, which has a false recognition rate of less than 0.0001%. At the same time, the anti-tailgating matrix made up of 16 sets of infrared sensors can find strange traffic behaviour in less than 0.3 seconds. During the music festival test, the system effectively stopped 127 tailgating intrusions, with only 0.08% of them being false alarms.
3. Passage and emergency response without sensors
Millimetre wave radar and UWB location technologies work together to make turnstiles able to let people "pass through without stopping." Users don't have to actively check; the system may automatically recognise them and unlock the gate from up to 1 metre away. A test project at a smart park showed that this technology has made traffic flow more smoothly, allowing 90 people to pass by every minute.
二,Analysing a case from the industry
1. Changing the schedule for the main entrance to the music festival
The music festival uses a "main gate+backup channel" system for graded control. AI cameras on the primary gate channel keep an eye on the flow of passengers in real time and change the speed as needed. LED screens on the backup channel help direct the flow of passengers. The system automatically switches the backup channel to "normally open" mode at busy times, and with manual verification, it can handle 12,000 individuals per hour.
2. Warning of reverse intrusion at a sports event
A certain international football competition uses both turnstiles and video cameras. When reverse incursion behaviour is detected, the gate locks right away and sets off an alarm. It also connects to nearby cameras to follow the intruder's path. The system stopped three unlawful intrusions throughout the event, which cut the reaction time down to 0.8 seconds.
3. Quickly putting rental models in picturesque regions
A certain gorgeous site rents out turnstiles for big events that only last a short time. The gadget has a modular design and can be set up and debugged in less than 48 hours. At one music event, the rented turnstiles were linked to the ticketing system so that real-time monitoring of passenger flow heat maps could be done. This meant that the number of open turnstiles could be changed on the fly, cutting down on wait times by 60%.
三,Problems and solutions in technology
1. Costs of maintenance and wear on machines
Using turnstiles a lot can rapidly wear down the mechanism. By using ceramic bearings and materials that lubricate themselves, one company has made their equipment last for 5 million passes. The remote diagnostic system can also keep an eye on the movement's temperature, vibration, and other factors in real time and let you know ahead of time if there is a chance of a problem.
2. Ability to handle really bad weather
The rotating gate needs to be able to handle extreme weather like heavy rain and high temperatures when it's outside. A certain model of product has an IP65 protection level design and a heating system that lets it work reliably in temperatures between -20 and 60 degrees Celsius. During the music festival, when it was raining heavily, less than 0.5% of the equipment broke down.
3. Protecting privacy and data security
The turnstile must follow the Personal Information Protection Law when it collects biometric data. A system employs the edge computing architecture to store data on a local server and the national security algorithm to encrypt the transmission. The programme passed Level 3 authentication at a specified government event to make sure that the data was safe.
