一套完整的DCS系统如何建立?DCS控制系统,对于没有经手过的人员来说十分神秘,只要做过,就没那么难,现在,浙大中控DCS卡件厂家就简要梳理一下,DCS系统的组态、步骤和基本思路。
How to establish a complete DCS system? The DCS control system is very mysterious to those who have not handled it. As long as it has been done, it will not be so difficult. Now, the manufacturer of the DCS card of Zhejiang University Central Control will briefly sort out the configuration, steps and basic ideas of the DCS system.
确认DCS厂家
Confirm DCS manufacturer
拿到项目后,要确认DCS控制系统的类型及供货厂家。了解DCS的硬件和软件的性能,一般厂家会组织培训。根据设计院提供的初步点数,确定DCS卡件数量,一般不少于30%的余量。
After receiving the project, confirm the type and supplier of DCS control system. To understand the performance of DCS hardware and software, general manufacturers will organize training. The number of DCS cards shall be determined according to the preliminary points provided by the design institute, and generally not less than 30% margin.
点表整理
Point table sorting
点表整理根据设计院提供的相应图纸,分单元整理点表,一般整理在EXCEL表中,包括位号、名称、信号类型、量程、单位、报警值(如果有的话),统计I/O点数。
The point table shall be sorted out according to the corresponding drawings provided by the design institute, and the point table shall be sorted out by unit, generally in the EXCEL table, including tag number, name, signal type, range, unit, alarm value (if any), and I/O points shall be counted.
I/O通道分配
I/O channel assignment
根据DCS厂家提供的卡件类型具体分配DCS的I/O通道,根据测点的类型分配到具体通道中来,一定仔细,不要出错。
The I/O channel of DCS shall be allocated according to the card type provided by the DCS manufacturer, and the I/O channel shall be allocated to the specific channel according to the type of measuring point. Be careful not to make mistakes.
根据I/O点数完成硬件配置
Complete hardware configuration according to I/O points
不同品牌的DCS系统硬件配置不同,但配置思路和方法是相同的:DCS系统硬件都是根据现场准确需求和DCS系统I/O点数来确定的。
DCS system hardware configurations of different brands are different, but the configuration ideas and methods are the same: DCS system hardware is determined according to the accurate on-site requirements and DCS system I/O points.
软件安装
Software installation
一般由DCS厂家的人员来进行安装,检查配置,启动系统,只做好配合即可。
Generally, the DCS manufacturer's personnel will install, check the configuration, start the system, and only cooperate.
根据点表作下位组态
Make the lower configuration according to the point table
根据DCS厂家提供系统,启动组态软件;
Start the configuration software according to the system provided by the DCS manufacturer;
将点表和相应的通道对应起来,千万别出错;
Match the point table with the corresponding channel, and do not make mistakes;
浙大中控DCS卡件
根据控制方案组态PID调节回路;
Configure PID control loop according to control scheme;
组态纯显示回路;
Configure pure display circuit;
组态开关量控制回路及小的联锁回路,如泵的启停;
Configure switch control circuit and small interlocking circuit, such as pump startup and shutdown;
有顺序控制,组态顺控部分;
There is sequence control, and the sequence control part is configured;
第三方设备的MODBUS通讯。
MODBUS communication of third-party equipment.
DCS显示控制画面
DCS display control screen
这部分很重要,用户看到的是画面,其他看不到。拿到DCS流程图,多看几遍,基本弄通物料流向和过程,再与甲方用户沟通,那几部分放在一个显示面上。
This part is very important. The user can only see the screen. Get the DCS flow chart, read it several times, basically understand the material flow direction and process, and then communicate with Party A's users, and put those parts on one display.
在系统画面组态软件中先把画面画出来,再联系甲方工艺人员一块修改画面,直至满意为止。为了提高效率,尽量选用子图的模式。
Draw the picture in the system picture configuration software, and then contact the process personnel of Party A to modify the picture until they are satisfied. In order to improve efficiency, sub graph mode shall be selected as far as possible.
至此,一套完整的DCS系统基本建立起来,随着,调试的过程中不断完善,终形成一套完整的DCS系统。更多相关事项就来我们网站http://www.sdjkyqyb.com咨询吧!
So far, a complete set of DCS system has been basically established. With the continuous improvement in the process of debugging, a complete set of DCS system has finally been formed. Come to our website for more information http://www.sdjkyqyb.com Consult!
