本文介紹了基于C8051F206 單片機的汽車制動踏板力及行程檢測儀的設計方案，給出了硬件線路結構圖及軟件程序框圖。本系統采用單片機技術，配以多個傳感器，能快速檢測出機動車離合器液壓制動器踏板行程以及制動踏板力和手剎制動操縱力。采用液晶顯示器，整個系統采用菜單提示選擇和人機對話方式，實時顯示實測值和峰值。標準RS232 接口，多種通訊協議，方便與主控機靈活構成聯機測試系統。該儀器具有成本低、可靠性高、實用性強等特點。
關鍵詞：單片機，制動踏板力, 檢測儀
Abstract: This paper introduces a design scheme of a Monitor for Automobile Braking Force of Pedal based on single-chip computer C8051F206, The hardware structure and software program diagram was also studied. This system combines single-chip computer with multi sensor. It can measure parameters of automobile braking force of pedal and hand braking force quickly. The system was driven with menu to select and person-computer interlocutory way by LCD. The measured data and maxima data was displayed on real time. It also has the
communication function by RS232, for the convenience of management by PC, realizes networking management. It has the characteristics of low costs, high accuracy, high stability and high practicability.
Keywords: Single-chip Computer; force of pedal; Monitor
