高速公路门架数据采集终端设计

根据国内高速公路不停车收费系统ETC(Electronic Toll Collection)建设要求,本文以嵌入式ARM(Advanced RISC Machine)系统STM32作为开发平台,采用C语言开发一种用于高速公路ETC门架的基于HTTP协议的现场数据采集服务终端,提出总体设计概论,介绍终端系统各模块功能、相关技术及相关工作流程,进行终端系统设计与实现。与常见的数采系统相比,本系统通过HTTP嵌入式移植,利用多Socket连接技术进行以太网传输,以满足ETC系统建设的边缘处理要求,使高速公路ETC门架现场数采更加方便高效。

Design of Data Acquisition Terminal for Expressway Gantry

This paper proposes to develop a data acquisition terminal based on HTTP(Hyper Text Transfer Protocol) on expressway ETC(Electronic Toll Collection) gantry site according to construction requirements of domestic expressway toll collection system ETC. The proposed terminal uses embedded ARM(Advanced RISC Machine) system STM32(SGSTHOMSON Microelectronics 32) as development platform and C programming language. This paper puts forward an overview of overall design, introduces module functions of the terminal system, related technologies and work flow, and carries out design and implementation of the terminal system. Compared with other data acquisition systems, this system uses HTTP embedded transplantation and multiple Socket connection technology for Ethernet transmission, so to meet edge processing requirements of ETC system construction and improve convenience and efficiency of data acquisition on expressway ETC gantry site.
