摘  要

 隨著電子技術的迅速發展，特別是電子技術在汽車方面的應用，給汽車向智能化發展帶來了根本性的改變。由于電子技術在汽車方面的廣泛應用,對汽車測量技術也向智能化發展。
 本文首先描述系統硬件工作原理，并附以系統結構框圖加以說明，著重介紹了本系統所應用的各硬件接口技術和各個接口模塊的功能及工作過程；其次，詳細闡述了程序的各個模塊和實現過程。本設計以數字集成電路技術為基礎，單片機技術為核心。本文編寫的主導思想是軟硬件相結合，以硬件為基礎，來進行各功能模塊的編寫。本系統以單片機的KEIL C51語言進行軟件設計，增加了程序的可讀性和可移植性,為了便于擴展和更改，軟件的設計采用模塊化結構，使程序設計的邏輯關系更加簡潔明了。
 其中本文用PROETEUS軟件進行模擬仿真，使硬件仿真變的簡單化。
    本系統實現了可編程電阻箱,即在一定范圍內可得到任意電阻。可以說是標準電阻發生器。
 
 關鍵詞　  單片機；網絡電阻；PROTEUS仿真；可編程電阻。

Abstract
 As electronic technology developing rapidly, especially in the automobile electronic technology, the applications to the development of intelligent vehicle bring fundamental change. As electronic technology in a wide range of vehicle applications, the measurement of vehicle technology develop to intelligence.   
 This paper first describes the system hardware working principles, along with the system architecture block diagram illustration, highlights of this system by the application of technology and hardware interface module interface all of the functions and work processes; Secondly, a detailed explanation of procedures for the various modules and the realization process. The digital IC design technology-based, single-chip computer technology at the core. This paper prepared by the dominant thinking of the combination of hardware and software to hardware-based, for the preparation of functional modules. The system MCU KEIL C51 language software design, the procedures increase the readability and portability. In order to facilitate the expansion and changes to the software design modular structure, so that the logic of the design process even more succinct and clear.
 In this paper, which PROETEUS software simulation, simulation hardware change the simplistic.
 The system achieved a programmable resistor boxes, in a certain range that is available within any resistance. It can be said is standard resistance generator.
 
Key words　 SCM;       Network resistance;      Proteus simulation;
 Programmable resistor.
