[0026] 有报警发生,仪表面板下方图标闪烁,出现报警喇叭,并且数据柱上升。 [0026] The alarm occurs, the instrument panel below the icon is blinking, the alarm horn appears, and the data column rises.

[0027] 2、参数查询功能: [0027] 2, the parameter query functions:

“参数查询”功能是了解系统的各种测量参数和设定参数,仪表示值、上限报警值、上上限报警值、语音设定时间,操作人员可以很明了地查看各种参数,了解现场和系统的各种状况。 "Parameter query" feature a variety of measurement parameters and set parameters to understand the system, Gauges, high alarm value, the alarm limit values, voice set time, the operator can view a variety of parameters and clearly understand the scene and various conditions of the system.

[0028] 3、安装位置显示功能: [0028] 3, the installation position display function:

在装置平面图或在工艺流程中的“安装位置”画面上,详细地标明了各报警点的安装位置。 In a plan view on the device or process flow "installation position" screen, detail alarm indicating the installation position of each point.

[0029] 当有报警发生,在该画面上弹出“报警窗口”,在该“报警窗口”内显示该点报警设定值、仪表指示值、可能产生事故部位及原因、处理措施、报警曲线,并发出语音报警,可及时提醒操作人员进行检查。 [0029] When an alarm occurs, the pop-up "alarm window" on the screen, displaying the alarm set point value, meter indication value, location and cause of the accident may occur, treatment measures, the alarm curve in the "alarm window", and a voice alarm, alert the operator can promptly check.

[0030] 4、历史曲线查询功能: [0030] 4, historical curve inquiry:

显示报警器测量值曲线,并显示报警极限值,可查询测量值是否超出上限值、上上限报警值、仪表失灵极限值,为操作人员提供了良好的工作界面。 Alarm curve measurement values, and alarm limits, can query whether the measured value exceeds the upper limit and the upper limit alarm, the meter failure limit value, provides a good working interface for the operator.
