Research On Overload Control System Of Passenger Car

Road passenger transport with a wide coverage,accessibility,extension and construction of the advantages of rapid deployment,has been the more people of all ages,and always other means of transport can not be replaced.In recent years,the vehicle overload operation of the illegal operation of repeated problems,the transport environment and passenger transport industry sustainable development has given some restrictions.Due to the particularity of road passenger transport,the vehicle in case of accidents are generally large-scale mass incidents,which brought to the country and the people not only economic losses,more is the immeasurable emotional damage.In order to control the bus overload effectively,reduce social harm,a variety of ways to control the overloading of passenger cars have emerged.From the initial manual detection method to the bill detection method,and then by the bill monitoring method to the sensor detection method,and then to the recent use of video-based detection methods,these methods are to some extent on the phenomenon of overloading the bus played a certain role.But these methods will not only spend a lot of human and financial resources,and sometimes the control effect is not very good.Combined with the development of bus overload control system,this paper attempts to use the bus detection module based on infrared thermal imaging combined with single-chip control,the overload detection and control of the bus.STM32 microcontroller as the core control module,it not only has high integration and low power consumption characteristics,but also has a wealth of I/O ports and USB interface,and can be USB from the external memory to read and output the relevant audio signal,integrated Advanced connection-oriented peripherals,you can achieve a variety of functions on the device can integrate a variety of functions,can be very good to meet our development needs.At the core of this paper is based on the infrared image of the car to identify,first by the infrared thermal imager to collect the infrared image of the first median filter,followed by the processing of infrared images for moving target detection,the background and infrared image sequence,And finally through the contour extraction algorithm to extract the target contour and Gavrila tree template to match,combined with the photoelectric sensor based on the car to identify and determine the specific number of passengers.The program to achieve intelligent management,not only to improve the accuracy of the number of passenger cars statistics,but also real-time monitoring and self-prediction,and has a complete function,the implementation of semi-automatic rule super mode,to achieve digital monitoring and management,so that vehicles do not Manual inspection,for overloaded vehicles can be real-time monitoring of vehicle information,real-time record the situation inside the car,and the situation of the car statistics and analysis.For overloaded vehicles,on the one hand the core control module will automatically start the alarm module,on the other hand can also be based on the default number of nuclear carrying out the system analysis,spontaneous to make predictions,control the bus engine,limit the bus abnormal Driving.Greatly reducing the overload caused by the traffic risk,to ensure traffic safety.
