摘要
本系统采用P89C51RD2单片机组成卡车工况监测系统,将工况信息存贮于具有容量大、安全保密、价格低廉等优点的SLE4428逻辑加密IC卡中,并以其为载体将工况数据传送到调度室微机,以便于调度人员调度管理,适用于卡车车辆较多的场合,文中给出了整个系统的工作原理及SLE4428卡的接口及程序。
This truck working condition monitoring system adopts P89C51 RD2 single-chip computer, stores working condition information in logic encrypts IC card with advantage such as large capacity?safe and secret?cheap etc. and conveys the working condition data to the computer of dispatching office with the carrier of IC card. So that truck transportation can be managed better by the dispatcher. This system is suitable for more truck vehicle occasions. The principle of the whole system and interface and program of SLE4428 card are provided in the paper.
