Development Of Intelligent Iron Shoes System Based On Wireless LAN

Train slips are one of the frequent accidents that occur when operating railway transfer stops,and they result in significant losses for the department of railroad transportation.To lessen the likelihood of this mishap,new precautions must be taken.Due to their benefits,such as excellent portability and being less constrained by regional environments,iron shoes are a type of anti-sliding device for trains that are frequently used.There are currently issues with non-standard actual placement,a heavy workload of periodic inspections,laborious manual records of incoming and outgoing shipments,missing payments,missing withdrawals,and no alarm,as well as accidental theft because traditional iron shoes lack intelligence.A new intelligent iron shoe management system with features like effective anti-slip,real-time monitoring,and data management based on the original iron shoes by combining new sensor technology is highly necessary in order to grasp the working dynamics of iron shoes in real time and promptly understand the working status of iron shoes in the field.As a result,this paper concentrates on three facets of iron shoe terminal system design,wireless LAN data transmission,and terminal data management.By contrasting the traits of existing common local area networks and combining the demands of data transmission security,low power consumption,and long-distance transmission,a data transmission method based on Lora LAN is proposed in order to increase the efficiency and security of data transmission.The design of the wireless local area network has been finished,along with the choice of Lora modules,the definition of data packet formats,the setting up of gateways,and the related transmission module capability tests in challenging environments.With the addition of additional functional modules including posture detection,laser ranging,and Lora wireless transmission,this article enhances and modifies the original iron shoe terminal in accordance with the overall functional needs.With STM32L051C8T6 serving as the control core,it completes the design of the PCB board and creates the hardware schematic layout for the iron shoe terminal.The terminal’s embedded software design was completed and the appropriate functional modules were evaluated using the state machine approach.This paper conducts extensive research on the gyroscope pose detection algorithm and suggests the idea of extending the Kalman filter algorithm to accomplish pose calculation in an effort to ensure the standardization of the placement of anti-slip iron shoes.In order to incorporate the error matrix into the state update procedure,this model makes use of the complementary concept of angular velocity sensors and accelerometers.The observed accelerometer values are used as predictive variables after geometric transformation,and the Kalman gain is solved based on the best covariance estimation of the predictive variables.The correctness of the model’s pose calculation was verified by compiling in the Matlab environment.Finally,a multithreaded technique is employed to provide data receipt and a My SQL database is used for data management in order to achieve dependable reception and effective administration of terminal data by the upper computer software.The upper computer software,which was designed and created using the C++Builder integrated development environment,is now complete.The safe,effective,and intelligent administration of iron shoes is made possible by the data table’s logical architecture,which also ensures the efficiency of data storage,the accuracy of information records,and the convenience of data querying.
