摘　　要：中国矿业大学 (北京校区 )研制的强力输送带全断面实时透视仪 ,最初在 3 86微机中采用了特制的图象处理卡VP12 ,并配有专用图象监视器CASPER ,后来采用了ET60 0 0显卡 ,皮带图象可直接在微机屏幕上显示。由于微机更新换代极快 ,一年后该显卡在市场上已很难买到 ,只好改为Trident9685显卡 ,而后又改用TNT2型等。每改换一次显卡 ,必须找出现卡驱程的原代码 ,从新编写显程 ,而原代码又很难找到。为了避免这种麻烦 ,采用了VBE标准编程 ,只要修改显卡的设置模式序号 ,程序就不用改写。Full-transect detector for the conveyer belt with steel wire ropes is studied by CUMTB. At first special manipulating cardVP12 in computer386 with image monitor CASPER was adopded for the belt image display. Afterwards the belt image could be directly displayed on screen of computer by using display carde ET6000.But in the next year the card could not be boaght due to quick development of computer technology. Therefore it was compelled to use Trident9658, next TNT2 and so on. At every change primary code of corresponding driver and program software must be found out.The primary code was very difficult to find out, in order to avoid the troubles the Standard by VBE--VESA(Video Electronics Standards Association) BIOS Extension--is adopded to program image display softwere.In this way the image display softwere needn't be reprogramed at a time changing display card, when the display mode in the softwere for every card is modified.
