METSO ACN?CS邏輯8通道模塊卡件

通過對不同的DCS過程報警分級控制技術(shù)的研究發(fā)現(xiàn)，現(xiàn)階段現(xiàn)場工作使用的DCS裝置探測報警主要針對有毒、有害和可燃性的氣體，當(dāng)檢測到這幾種氣體出現(xiàn)時就會產(chǎn)生報警的行為。市場上的報警器具有多元化的特點，要保證DCS正常的工作要使用具有規(guī)范性的報警器。
在挑選報警器的過程中應(yīng)注意以下幾個規(guī)則：
● 必須能夠為監(jiān)測有毒有害氣體等的監(jiān)測器和其他的連接部件提供供電的功能；
● 能夠在檢測到有毒有害氣體后，發(fā)出合適的報警信號直至有人發(fā)現(xiàn)，大大提高報警功能的有效性；
● 監(jiān)測可燃氣體的范圍要在正常的爆炸范圍內(nèi)；
● 對有毒有害氣體的濃度和測量范圍有所適應(yīng)，保障在正常范圍內(nèi)檢測到有害氣體的出現(xiàn)；
● 指示報警設(shè)備是較為重要的，是決定是否能夠正確報警的關(guān)鍵，在挑選和購買的過程中應(yīng)挑選具備消防設(shè)備和聯(lián)鎖保護使用功能的報警設(shè)備；
● 報警器要具備獨立監(jiān)測和報警的功能，保證每一個報警器只對負責(zé)范圍內(nèi)的有毒有害氣體監(jiān)控；
● 安裝的報警器應(yīng)具備持續(xù)報警的功能，在使用的過程中若發(fā)現(xiàn)有毒有害氣體的泄露應(yīng)開啟報警功能，當(dāng)濃度降低的情況下，報警器也需要持續(xù)的報警以保證及時地發(fā)現(xiàn)有毒有害氣體的泄露。
報警器是報警分級控制技術(shù)的關(guān)鍵，在現(xiàn)代DCS過程報警分級控制技術(shù)的使用過程中，負責(zé)人員可根據(jù)以上幾種原則挑選和使用報警器，以保證控制現(xiàn)場的安全規(guī)范性。Through the research on different DCS process alarm hierarchical control technologies, it is found that the DCS devices used in field work at this stage are mainly used to detect and alarm toxic, harmful and combustible gases. When these gases are detected, the alarm will occur. Alarms on the market have diversified characteristics, and standardized alarms should be used to ensure the normal operation of DCS.

The following rules should be noted during the selection of alarms:

● It must be able to provide power supply for monitors and other connecting parts that monitor toxic and harmful gases;

● After detecting toxic and harmful gases, it can send out appropriate alarm signals until someone finds them, greatly improving the effectiveness of the alarm function;

● The range of combustible gas monitoring shall be within the normal explosion range;

● Adapt to the concentration and measurement range of toxic and harmful gases to ensure that the presence of harmful gases can be detected within the normal range;

● Indication alarm equipment is more important, and is the key to determine whether it can alarm correctly. In the process of selection and purchase, alarm equipment with fire protection equipment and interlocking protection functions shall be selected;

● The alarm shall have independent monitoring and alarm functions to ensure that each alarm only monitors toxic and harmful gases within its scope of responsibility;

● The installed alarm shall have the function of continuous alarm. If the leakage of toxic and harmful gases is found during use, the alarm function shall be started. When the concentration is reduced, the alarm shall also give continuous alarm to ensure that the leakage of toxic and harmful gases is found in time.

The alarm is the key to the hierarchical alarm control technology. During the use of the modern DCS process alarm hierarchical control technology, the responsible personnel can select and use the alarm according to the above principles to ensure the safety and standardization of the control site.
