基尔的玛克机器制造公司在不来曼的克鲁伯——阿脱拉斯电子公司协作下,在其试验基地为柴油机试验安装了一套由过程计算机控制的测量数据采集和处理装置。使用这套装置,在试验过程一结束就可以试验报告形式或图形的形式给试验人员提供原始的以及经换算好的试验数据。可移式的 EPR 1100过程计算机可以进行发动机部件的应力和强度试验,进行发动机试验台上的数据处理,以及进行换气过程的测量。试验台及试验件等常规设备由发动机制造厂制备。与过程计算机相关的工作项目、敷设电路、测试设备和过程计算机所需编排的程序等,则由两家公司合作完成。本文在指出发展柴油机中采用过程计算机的重要意义,即缩短试验时间和减少研制经费后,详细叙述了两个实用的例子。第一个例子叙述柴油机试验台上的测量情况,在表一中给出了所有测量结果;第二个例子叙述换气过程的研究试验。图1是该两例的测量设备,图2是测量后立即用 X-Y 绘图仪绘出的结果(增压压力、气缸压力、排气压力)。图3表示附加提供的空气流量曲线。因为过程计算机有广泛运用的可能性,本文选用了一个大容量的作业和数据外围设备(图6),以满足静态的和动态的测量。计算机和硬件由高效率的软件提供支持,它们以框图形式表示在图7。
In collaboration with Krupp-Ahreras Electronics in Bremen, Mark’s machine manufacturing company Kiehl installed a computer-controlled measurement data acquisition and processing unit for diesel testing at its test site. Using this set of devices, the test report can be provided in the form of a test report or graphical form to provide the test personnel with original and converted test data as soon as the test procedure has been completed. The portable EPR 1100 process computer performs stress and strength tests on engine components, performs data processing on the engine test bench, and measures ventilation. Conventional equipment such as test stands and test pieces is prepared by the engine manufacturer. Work programs related to process computers, procedures for laying out circuits, test equipment, and procedures required for process computers are done by the two companies. After pointing out the importance of using process computers in the development of diesel engines, this paper elaborates on two practical examples after shortening the test time and reducing the development expenses. The first example describes the measurement conditions on a diesel test bench, and all the measurements are given in Table 1. The second example describes the test of the ventilation process. Figure 1 shows the two measuring devices. Figure 2 shows the results of the X-Y plotter immediately after the measurement (boost pressure, cylinder pressure, exhaust pressure). Figure 3 shows additionally provided air flow curves. Because of the wide availability of process computers, this article selected a high-volume job and data peripheral (Figure 6) to meet both static and dynamic measurements. Computers and hardware are supported by highly efficient software, which is shown in block diagram form in Figure 7.
