Design Of Field Bus Management System For Object Oriented Perception Technology

With the development of digitalization and informationization,people's demand for travel is becoming more and more urgent.As an environment-friendly travel mode,public transport vehicles have become an indispensable means of daily travel.The increasing number of public transport vehicles and the increasing number of bus parking sites make the existing management model no longer suitable for the development of public transport companies.In order to meet the needs of digital and information society,it is urgent to design and develop a complete bus parking management system.According to the management characteristics of the bus parking lot,this paper makes an in-depth excavation and analysis,and realizes the real-time monitoring and key data tracking of the various links of the bus in the parking lot,such as vehicle security inspection,ticket collection,repair,energy consumption,cleaning,positioning and so on,by using the Internet of Things perception technology,and integrates the various links into the on-site management integration.Machine system.At the same time,using custom transmission protocol and data format to solve the problem of heterogeneous data exchange in distributed environment,and provides data interface for other management system.In the aspect of vehicle positioning,a vehicle positioning method based on GPS and RFID technology is proposed.GPS technology is used to obtain vehicle positioning information in open-air parking lot,and RFID technology is used to obtain vehicle positioning information in indoor or three-dimensional parking lot.For outdoor positioning,GPS static drift is corrected by combining coordinates and velocities;for solving the weak position of GPS signal,the positioning algorithms implemented by RFID tags with different power supply modes are proposed,and the occupancy of parking space is determined according to the image calculation mode,so as to solve the calculation of saturation in parking lot.The problemThe development and implementation of this system solves a series of problems,such as low efficiency,many loopholes,high cost of operation and maintenance,which appear in the process of bus yard management.It makes the company management change from the traditional manual mode to the data intelligent management mode,greatly accelerating the pace of development of urban intelligent bus system.
