Research On The Anti-tailing Method Of Channel Gate And Its System Implementation

Traditional types of single-door gates are not guaranteed due to safety and reliability,and will gradually be replaced by smarter,more accurate and more efficient self-service ticketing methods.This paper studies,designs and implements a channel gate control system with anti-tailing function,which mainly completes the overall design of the gate hardware system and software system,and designs the release control flow of pedestrian self-service clearance in detail,focusing on the basis of research on trailing recognition technology for measuring light curtains.Firstly,a pedestrian pedestrian perception method based on measurement light curtain is proposed.A pedestrian clearance data analysis model based on measurement light curtain is established to realize feature extraction of data.A trailing customs clearance based on GA-MSPNN neural network model is proposed.The event static identification method uses genetic algorithm to optimize the smoothing parameters of the hidden layer excitation function and improve the accuracy of trailing event recognition.A dynamic recognition method based on gait model for trailing customs clearance events is proposed.The Kalman filter of the dynamic model of the moving object tracks the customs clearance target,and analyzes whether the customs clearance target has the gait characteristics during pedestrian walking to determine whether there is a trailing event.Secondly,a double gate structure with anti-tailing function is designed by comparing and analyzing the advantages and disadvantages of different types of gates.The principles and methods of ergonomics are used to determine the range of space required for pedestrians to move within the channel,as well as the shape,dimensions and scope of use of the channel.At the same time,the mechanical structure,hardware layout and appearance structure of the channel gate system were completed,and the requirements of performance index,working mode and traffic identification ability required for the design of the gate system were put forward.Thirdly,according to the functional requirements of the channel gate system,the overall design of the hardware system of the anti-tailing channel gate is carried out.The design method of the motor drive control system and the motion control method of the swing gate are introduced in detail.The overall architecture design of the software system of the channel gate is carried out.A new self-service customs clearance service service process was designed.Completed the overall design of the PC software and the design of the pedestrian releasecontrol process.The system realizes the functions of channel release control,identity authentication,gate release control,pass identification and processing,and timeout response.Finally,the designed anti-tailing channel gate system is shown.By arranging the measuring light curtain on the experimental prototype platform,the static and dynamic two trailing identification algorithms are used to verify the common traffic conditions.The experimental results show that The trailing recognition algorithm of the pedestrian gait model has higher accuracy and is combined with the pedestrian clearance process to effectively prevent the occurrence of trailing events.
