The strong points of the profibus - dp single master control system are : low cost , simple plan , well expansibility , easy operation , credible communication and so on 采用这种硬件软件设计方式构成的profibus - dp单主站控制系统，具有成本低、设计简单、良好的可扩展性、操作方便、通信可靠、适应恶劣的工业环境等优点。
Optical measurement systems are of increasing importance for research and industry . today ’ s laser sensors are rigid to withstand industrial environments . surfaces are probed with respect to distance , velocity and surface structure 目前,激光传感器可以很好地适应工业环境,它可以测量物体表面的位移、速率和表面结构。
This pressure and force transducer is ideally suited for harsh industrial applications and for use in the construction of testing and manufacturing systems , where robustness and long - term stability are the main requirements 这款压强压力传感器特别适用于恶劣的工业环境，也可以用于检验设备和制造系统中，它满足坚固性和长期稳定性。
Their long - term stability , good corrosion resistance , high protection ip 67 and mechanical load rating also make the pressure sensors precision suitable for use in demanding measuring jobs in harsh industrial environments 该压力传感器的长期稳定性抗腐蚀性保护性ip 67和机械负载能力都很好，因此它适用于恶劣的工业环境中高要求的测试工作。
At the same time , the condition around the machines in the industry field is more complicated . the requirement is increasing to make those monitoring and controlling instruments more simple and ease of use from the field engineers 同时随着我们所处的工业环境越来越复杂，现场工程师不断增加了对监控这些工业环境设备的易用性、简单性的要求。
What ' s main research of the thesis is to make some research , based on the basic thought of the satisfactory control , into some problems of satisfactory optimization control with fuzzy objective and fuzzy constrains in the complex industry process 本文基于满意优化的基本思想，对复杂工业环境中存在模糊目标和模糊约束时的满意优化控制问题进行了探索和研究。
The second is that for a complicated system , for example , with many loops as well as many controllers , it is very difficult to give the direct relation between the parameters of processes and that of controllers 这主要有以下几方面原因：一是在工业环境下，对被控过程难以进行精确的数学描述。由于工业噪声所表现出来的多样性，最小二乘类等参数辨识方法的应用受到很大的限制。
There are two parts in this paper . the first , " new technology , usb & dsp " , consist of the evolution of the daq system , new features of daq system needed by modern industry , how the dsp & usb affect the system architecture 全文共分成两个部分，第一部分“新技术的出现? usb ， dsp ”主要描述了数据采集系统的演变，新型工业环境对数据采集系统的要求，新技术usb ， dsp的出现对数据采集系统设计的影响。
During the course of industrial manufacture , the determinacy of the industrial environment and illuminating conditions makes the ideas possible that industrial parts can be distinguished and classified rapidly and accurately . the system introduced below is the result of this idea 在工业生产中，工业环境和照明条件的确定性使得快速准确地判别分类出工业零件的想法成为可能，本系统就是在这种想法下应运而生的。
