| With the development of the world economy and the economy of our country,the demand of Toll Collection Electronic(ETC)system has become more and more important.The introduction of electronic toll collection system has a higher technical requirement for the ETC system,which can shorten the traffic time and improve the traffic capacity of toll lane.In recent years,rapid development of embedded system products has been gradually extended to various applications,resulting in very good agreement with the engineering requirements of embedded system’s advantages and etc lane system.Therefore,it is necessary to will be widely used in industrial control field of embedded system is introduced into the control system of etc lane.From the development of ETC in the country,the national highway network basically completed,but less than application scenarios for highway.Aimed at this situation,the subject of an app in the control system of parking fees scenarios embedded etc lane,to solve the problem of parking charges in traditional MTC efficiency is low,but the construction of ETC system to the high cost of dilemma.This paper firstly introduces the development requirements and system design framework of embedded ETC lane control system.Then in view of the connection lane controller of electronic charge equipment,vehicle detection equipment,traffic control equipment,information display equipment,license plate recognition equipment mainly external equipment,focusing on the description of the device driver program and device control program design and implementation.Then,the module and main flow of the lane control program and data communication program are designed in the system application software.The main task of the paper is the hardware scheme of the embedded ETC lane control system and the software to meet the needs of the function.According to the results of multi group system integration test and data analysis,it is determined that the design goal is reached in the function. |
