              2021-12-06 20:31:37 來源:http://www.eboudy.com/ 53

              應用在工業生產中的DCS系統,必然會因為一些不良因素的影響,而導致系統性能下降。比如環境溫度不合適導致的溫漂現象;比如因氧化現象導致接觸電阻過大,進而導致接地系統性能下降;比如環境濕度過大、腐蝕性氣體、灰塵等原因導致的硬件損壞;比如因為一些不正確操作導致的軟件功能損壞……
              The DCS system applied in industrial production will inevitably lead to the decline of system performance due to the influence of some adverse factors. For example, temperature drift caused by inappropriate ambient temperature; For example, the contact resistance is too large due to oxidation, which leads to the degradation of the performance of the grounding system; For example, hardware damage caused by excessive environmental humidity, corrosive gas, dust and other reasons; For example, the software function is damaged due to some incorrect operation
              因此定期對DCS系統進行檢查和維修,尤其是可能引起系統故障的關鍵點進行檢測和必要的部件更換,目的是將系統故障滅殺在萌芽狀態,延長系統使用壽命,保證DCS系統長期、、穩定運行。
              Therefore, the DCS system shall be inspected and maintained regularly, especially the key points that may cause system failure shall be detected and necessary components shall be replaced, in order to kill the system failure in the bud, prolong the service life of the system and ensure the long-term, stable and stable operation of the DCS system.
              一、中控室環境檢查
              1、 Environmental inspection of central control room

Check the cleaning condition: the doors and windows shall be closed and pay attention to dust prevention. The holes of cables shall be sealed. 3. Check the installation of the console: it shall be firm and free from vibration. 4. Check the power socket in the console: the connection of the socket shall be reliable and the reed shall not lose elasticity. 5. Check the anti-static floor: the support of the floor shall be connected reliably and stably.
              二、電子間環境檢查
              2、 Environmental inspection of electronic room
              1.檢查空調運轉情況:溫度要求16-25℃,濕度要求40-90。。2.檢查清潔狀況:門窗應關好,注意防塵。電纜的孔洞要求密封。3.檢查防靜電地板情況:地板的支架應連接可靠穩固。4.檢查控制柜安裝情況:應牢固沒有振動。5.檢查服務器柜內電源插座情況:插座的連接應可靠,簧片沒有失去彈性。6.檢查電磁干擾情況:電子間內不允許使用電焊機、沖擊鉆;機柜周圍3米范圍內不能使用無線通訊設備。
              1. Check the operation of the air conditioner: the temperature shall be 16-25 ℃, and the humidity shall be 40-90.. 2. Check the cleaning condition: the doors and windows shall be closed and pay attention to dust prevention. The holes of cables shall be sealed. 3. Check the anti-static floor: the support of the floor shall be connected reliably and stably. 4. Check the installation of control cabinet: it shall be firm and free from vibration. 5. Check the power socket in the server cabinet: the connection of the socket should be reliable, and the reed does not lose elasticity. 6. Check electromagnetic interference: electric welding machine and impact drill are not allowed in the electronic room; Wireless communication equipment cannot be used within 3M around the cabinet.
              三、系統供電檢查
              3、 System power supply inspection
              1.檢查DCS的廠用電電源:要求電壓單相AC200V~AC250V,頻率50HZ±1HZ。2.檢查系統的UPS供電,要求輸出電壓AC220V±1,頻率穩定度50HZ±1HZ。3.檢查電源切換裝置:回路指示燈是否正常,輸出線編號是否正確,標牌是否完整,接線端子是否發熱。
              1. Check the auxiliary power supply of DCS: the required voltage is single-phase ac200v ~ AC250V, and the frequency is 50Hz ± 1Hz. 2. Check the UPS power supply of the system. The output voltage shall be AC220V ± 1 and the frequency stability shall be 50Hz ± 1Hz. 3. Check the power switching device: whether the circuit indicator is normal, whether the output line number is correct, whether the label is complete, and whether the wiring terminal is hot.
               
              四、系統接地檢查

Shielding ground is strictly prohibited to be connected in series! 6. Grid cabinet: the cabinet body shall be grounded; The grid needs intrinsically safe grounding, and the grounding needs to be set separately. It is not allowed to be combined with other grounding, which is grid grounding. 7. Grounding inspection of UPS power supply: shell grounding and output grounding are protective grounding. 8. Check the grounding resistance of the above equipment.
              五、系統清灰
