应用在工业生产中的DCS系统,必然会因为一些不良因素的影响,而导致系统性能下降。比如环境温度不合适导致的温漂现象;比如因氧化现象导致接触电阻过大,进而导致接地系统性能下降;比如环境湿度过大、腐蚀性气体、灰尘等原因导致的硬件损坏;比如因为一些不正确操作导致的软件功能损坏……
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
因此定期对DCS系统进行检查和维修,尤其是可能引起系统故障的关键点进行检测和必要的部件更换,目的是将系统故障灭杀在萌芽状态,延长系统使用寿命,保证DCS系统长期、、稳定运行。
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、中控室环境检查
1、 Environmental inspection of central control room
1.检查空调运转情况:温度要求16-25℃,湿度要求40-90。2.检查清洁状况:门窗应关好,注意防尘。电缆的孔洞要求密封。3.检查操作台安装情况:应牢固没有振动。4.检查操作台内电源插座情况:插座的连接应可靠,簧片没有失去弹性。5.检查防静电地板情况:地板的支架应连接可靠稳固。
1. Check the operation of the air conditioner: the temperature is required to be 16-25 ℃, and the humidity is required to 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 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、电子间环境检查
2、 Environmental inspection of electronic room
1.检查空调运转情况:温度要求16-25℃,湿度要求40-90。。2.检查清洁状况:门窗应关好,注意防尘。电缆的孔洞要求密封。3.检查防静电地板情况:地板的支架应连接可靠稳固。4.检查控制柜安装情况:应牢固没有振动。5.检查服务器柜内电源插座情况:插座的连接应可靠,簧片没有失去弹性。6.检查电磁干扰情况:电子间内不允许使用电焊机、冲击钻;机柜周围3米范围内不能使用无线通讯设备。
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、系统供电检查
3、 System power supply inspection
1.检查DCS的厂用电电源:要求电压单相AC200V~AC250V,频率50HZ±1HZ。2.检查系统的UPS供电,要求输出电压AC220V±1,频率稳定度50HZ±1HZ。3.检查电源切换装置:回路指示灯是否正常,输出线编号是否正确,标牌是否完整,接线端子是否发热。
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、系统接地检查
4、 System grounding inspection
1.操作台:操作台要求接地,台内插座的地线要求接地,均为保护地。2.IT设备:计算机主机的外壳、服务器的外壳和交换机的外壳需要接保护地。3.电源柜:柜体要求接地,为保护地。4.服务器柜:柜体要求接地,柜内插座的地线要求接地,均为保护地。5.控制柜:柜体要求接地,为保护地;柜内信号线的屏蔽层需要在柜内单端接地,为屏蔽地。屏蔽地严禁串联!6.栅柜:柜体要求接地,为地;栅需要本安接地,接地需要单独设置,不允许和其他地合并,为栅地。7.UPS电源的接地检查: 外壳接地,输出地线接地,均为保护地。8.以上设备接地电阻检查。
1. Console: the console is required to be grounded, and the ground wire of the socket in the console is required to be grounded, which is protective ground. 2. IT equipment: the shell of computer host, server and switch shall be grounded. 3. Power cabinet: the cabinet body shall be grounded for protection. 4. Server cabinet: the cabinet body is required to be grounded, and the ground wire of the socket in the cabinet is required to be grounded, which is protective ground. 5. Control cabinet: the cabinet body shall be grounded for protection; The shielding layer of the signal line in the cabinet needs to be grounded at a single end in the cabinet, which is shielding ground. 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.
