在线监视 meaning in English
in-service monitoring
Examples
- A temperature distribution model is established by the infrared image processing and the crossing temperature is used to calibrate the temperature , so as to achieve on - line monitoring of the temperature profile
它通过红外图像处理来建立温度场分布模型，结合十字测温进行温度定标，实现了高炉温度场分布在线监视，为指导高炉布料提供了一种有效的途径。 - For complicated steam condition during startup or stop process of turbine , operators need to online monitor on the thermal status and control thermal stress of the unit sets ， but at present it ' s generally lack of effective ways , operators always do by his experience ， so it ' s difficult to promise safety and economic level of unit sets " operation
由于汽轮机在启停过程中蒸汽工况变化复杂，要求运行人员对机组的热状态进行在线监视，并对机组的热应力水平进行在线调整与控制,但目前普遍缺乏有效的途径，运行人员主要依据经验进行操作,难以保证机组运行的安全性与经济性。 - The primary measures for control precept are : sufficiently and effectively utilizing the the air compressors " interior data , realizing online surveillance and alarming for failure of the the air compressors " running interior parts ; letting the air compressors running by master and slave manner , by reasonable arranging the alignment of the air compressors , making the masters yielding pressed air and the slaves adjusting the pressure of the air . this decreases the times of loading and unloading greatly and the decreased failure of air compressors and low maintain ; at the same time we adopt abundant value of the set pressure for stabling the compressure . the air compressors become loaded or unloaded ahead by the abundant value ; caning unloading control for saving power , when the air compressors get along with unloading for a while , the system will stop them ; consummating the purposes for control , enhancing offline control for over - press and low - press , continual loading control and unloading control
经过分析研究，针对原来存在的问题，在控制方案上主要的改进措施有：充分、有效地利用了空压机的内部参数数据，对空压机的内部部件的运行情况实现了在线监视及故障报警；对空压机采用了主、辅结合的运行方式，通过对空压机加、卸载队列的合理排序，使空压机自动实现主机产气、辅机进行气压调节，减少了空压机的加载和卸载次数；在压缩空气压力的稳定上进行了裕量控制，在压缩空气压力不到供能品质所规定的上、下根就根据一定的裕量提前进行卸载和加载操作；在节约电能方面对空压机进行了卸载停机控制，当空压机在一定时间内一直处于卸载状态，系统就认为该空压机没有运行的必要，自动将其停机；完善了控制效果，增加了超压低压脱网控制、连续加载控制、连续卸载控制等功能。
