In this paper, a high integrated and intelligent digital dsp - spm system is developed based on the nspm6800 spm manufactured by the beijing zhongke mechanical & electrical equipment co. at present, the pc of spm system is burdened with not only sending and receiving data, but also disposing of image, which hinders the enhancement of speed of the system. in addition, as the function of spm is expanding, including tappingmode afm, efm, mfm, scm, etc, one hand, it amplifies the range of the application of spm, on the other hand it also means that the task of autocontrol and data transfer heavier. the advantages offered by the dsp compared to analog systems include considerable flexibility in the choice of the signal processing algorithm and greater ease in managing control parameters by the host computer, which are very important for the improvement of spm
本課題以北京市中科機電設備公司的nspm - 6800型掃描探針顯微鏡為基礎，重新設計了以dsp為控制核心的控制系統，主要解決原系統存在的以下問題： （ 1 ） pc機既要實時控制數據的採集與發送，又要進行圖像的后處理，整個系統的實時性難以達到要求； （ 2 ）隨著spm功能的擴展，一方面包括輕敲式原子力顯微鏡、電場力、磁場力、掃描容場顯微鏡等技術在內的spm技術擴展了儀器的測試范圍和功能，另一方面也意味著自動控制量的增加和數據處理量的增加； （ 3 ） 16位a d 、 d a都採用的是購買的板卡，也通過isa槽插在pc機內，成本高，不利於擴展； （ 4 ）另外，數字板通過isa槽插在pc機內，易受于擾，而且給安裝帶來不便。 -
