【摘要】：傳統(tǒng)的振動測試系統(tǒng)存在著自動化水平低、可擴展性差、可靠性不強等問題，很難滿足大型復雜機械裝備多點振動監(jiān)測的要求。CAN總線具有穩(wěn)定性高、可靠性強等優(yōu)點，在工業(yè)自動化領域中應用越來越廣，基于CAN總線的系統(tǒng)設計逐漸成為該領域發(fā)展的一大趨勢。本課題將CAN總線技術(shù)應用于振動測試系統(tǒng)，利用DSP處理器的實時數(shù)據(jù)處理能力設計了基于CAN總線的振動測試系統(tǒng)。本論文主要做了如下工作： 首先，介紹了CAN總線技術(shù)，論述了CAN總線的工作原理并詳細分析了CAN總線協(xié)議，在此基礎上，設計了基于CAN總線振動測試系統(tǒng)的整體框架。其次，采用TMS320F2812型號的DSP處理器，設計了滿足系統(tǒng)要求的整體結(jié)構(gòu)框架。該框架主要包括數(shù)據(jù)采集模塊、信號調(diào)理模塊、DSP最小系統(tǒng)模塊、CAN通信模塊�；谠摽蚣苤攸c設計了以下內(nèi)容：①通過分析壓電式加速度傳感器的結(jié)構(gòu)和工作原理并結(jié)合本課題的需求，選用ICP加速度傳感器對振動信號進行采集，設計了ICP傳感器的供電電路。②根據(jù)系統(tǒng)需要，選取主控制器芯片，分析并設計了系統(tǒng)供電電路，設計了以模擬開關(guān)（CD4051）和集成運算放大器（LM324）構(gòu)成的信號調(diào)理電路。在分析CAN總線原理和協(xié)議的基礎上，選取CAN收發(fā)器SN65HVD232D芯片，完成了通信硬件接口電路設計，實現(xiàn)了數(shù)據(jù)通信。③運用輔助軟件Protel99SE完成了整個系統(tǒng)原理圖的設計，并繪制了相應的PCB圖。在CCS環(huán)境下，使用C語言編程，完成了A/D采樣及CAN通信的軟件編程，最后將數(shù)據(jù)傳送至上位機。 基于CAN總線的測試系統(tǒng)易于擴展，穩(wěn)定性高，使用及維護方便，實現(xiàn)了PC機和DSP之間數(shù)據(jù)的可靠、快速傳輸，本系統(tǒng)采用模塊化結(jié)構(gòu)設計，具有一定的通用性。
