DCS卡件在DCS系统发挥着不可忽视的作用,再加上DCS系统具有较高的灵活性与扩展性,能够热插拔,下面来讲讲
浙大中控DCS卡件与模块的区分吧。
The DCS card plays an important role in the DCS system. In addition, the DCS system has high flexibility and scalability, and can be hot-swapped. Next, let's talk about the difference between the DCS card and the module of Zhejiang University Central Control.
DCS卡件按照信号类型划分,主要有4-20mA输入输出、热电阻、数字量输入输出(即开关量)、脉冲卡、热电偶、通讯卡。DCS卡件的功能也就是将不同类型的信号转换处理。
DCS cards are divided according to signal types, mainly including 4-20mA input and output, thermal resistance, digital input and output (i.e. switching value), pulse card, thermocouple and communication card. The function of DCS card is to convert different types of signals.
DCS卡件有一款重要的I/O卡,I/O卡是INPUT/OUTPUT的缩写,主要是负责接收现场的模拟量和数字量信号然后转换成DCS控制器能接收的数字信号的卡件,同时将DCS控制器所发出的指令转换成模拟量信号和数字量信号到现场仪表。主要起中间转换卡的功能,有的厂家也叫数据转发卡。
The DCS card has an important I/O card. The I/O card is the abbreviation of INPUT/OUTPUT. It is mainly responsible for receiving the analog and digital signals on the site and converting them into digital signals that the DCS controller can receive. At the same time, it converts the commands sent by the DCS controller into analog and digital signals to the field instruments. It mainly serves as an intermediate conversion card. Some manufacturers also call it data transfer card.

DCS卡件指的是DI/DO/AI/AO卡件。而模块是卡件上其中的一个DI/D0/AI/AO模块。也就是说一个DCS卡件上有很多模块。卡件应该指可安放端子模块的一个集合,如8路AI模块,16路DI模块。
DCS card refers to DI/DO/AI/AO card. The module is one of the DI/D0/AI/AO modules on the card. That is to say, there are many modules on a DCS card. Card should refer to a collection of terminal modules that can be placed, such as 8-way AI module and 16-way DI module.
此外系统的日常维护是DCS系统稳定高能效运行的基础,主要的维护工作有以下几点:
In addition, the daily maintenance of the system is the basis for the stable and efficient operation of the DCS system. The main maintenance work includes the following points:
1)完善DCS系统管理制度。
1) Improve the DCS system management system.
2)尽量避免电磁场对DCS卡件的干扰,避免移动运行中的操作站、显示器等,避免拉动或碰伤设备连接电缆和通讯电缆等。
2) Try to avoid the interference of electromagnetic field on DCS card, avoid moving the operating station, display, etc. in operation, and avoid pulling or bumping the equipment connecting cable and communication cable, etc.
3)注意防尘,现场与控制室合理隔离,并定时清扫,保持清洁,防止粉尘对元件运行及散热产生不良影响。
3) Pay attention to dust prevention, properly isolate the site from the control room, regularly clean and keep clean to prevent dust from adversely affecting the operation and heat dissipation of components.
4)保证空调设备稳定运行,保证室温变化小于±5℃/h,避免由于温度、湿度急剧变化导致在系统设备上的凝露。
4) Ensure the stable operation of the air conditioning equipment, ensure that the room temperature change is less than ± 5 ℃/h, and avoid condensation on the system equipment due to rapid changes in temperature and humidity.
5)做好控制子目录文件的备份,各自控回路的PID参数、调节器正反作用等DCS卡件及系统数据记录工作。
5) The backup of the control sub-directory file, the PID parameters of the respective control circuit, the positive and negative effects of the regulator and other DCS cards and system data records shall be done well.
6)检查控制主机、显示器、鼠标、键盘等硬件是否完好,实时监控工作是否正常。
6) Check whether the control host, display, mouse, keyboard and other hardware are in good condition and whether real-time monitoring works normally.
7)查看故障诊断画面,是否有故障提示。
7) Check the fault diagnosis screen to see if there is a fault prompt.
