基于CAN总线技术的市场运营数据采集器设计

Design of market operation data collector based on CAN Bus technology

针对传统的市场运营数据采集器存在实时性差的问题,设计了一种基于CAN总线技术的市场运营数据采集器。以CAN总线技术为设计中心,重点设计了市场运营数据采集器的结构部分,主要包括存储芯片、控制器与总线收发器,其中存储芯片用来存放市场运营数据,控制器与总线收发器主要用来接收与发送市场运营数据。市场运营数据采集器的程序部分,设计在线数据库,管理市场运营数据,并提供市场运营数据采集器的初始化功能,以此完成了基于CAN总线技术的市场运营数据采集器的设计。经实验证明,此次设计的基于CAN总线技术的市场运营数据采集器比传统采集器信息采集实时性好,具有工作稳定、可靠和成本低的优点,满足了市场运营数据采集需求。

In view of the poor real-time performance of the traditional market operation data collector,a market operation data collector based on CAN bus technology is designed.Taking CAN bus technology as the design center,the structure of market operation data collector is mainly designed,including memory chip,controller and bus transceiver,in which memory chip is used to store market operation data,controller and bus transceiver are mainly used to receive and send market operation data.In the program part of the market operation data collector,the online database is designed to manage the market operation data,and the initialization function of the market operation data collector is provided,so as to complete the design of the market operation data collector based on CAN bus technology.Experiments show that the design of the market operation data collector based on CAN bus technology has better real-time performance than the traditional collector with the advantages of stable,reliable and low cost,and it meets the market operation data collection requirements.
