DCS系统应进行从设计、施工、调试、运行维护进行全过程全 方 位管理。作为系统维护人员要根据系统配置和生产运行特点,制定科学合理的维护策略和方法,加强系统维护,对运行中出现的故障,具体问题具体分析,及时处理,确保DCS系统稳定可靠运行。机组检修期间应对DCS卡件应进行彻 底的维护,维护主要包括:
DCS system shall carry out all-round management in the whole process from design, construction, commissioning, operation and maintenance. As the system maintenance personnel, they should formulate scientific and reasonable maintenance strategies and methods according to the system configuration and production and operation characteristics, strengthen system maintenance, analyze and deal with the faults and specific problems in time, so as to ensure the stable and reliable operation of DCS system. DCS card shall be thoroughly maintained during unit maintenance, mainly including:
(1)利用机组检修时间逐个复位DCS系统的DPU、CPU和操作员站及数据站;删除组态中的无效I/O点,对组态进行优化。
(1) Use the unit maintenance time to reset DPU, CPU, operator station and data station of DCS system one by one; Delete invalid I / O points in the configuration and optimize the configuration.
(2)系统冗余测试:对冗余电源、服务器、通讯网络进行冗余测试。注意系统各设备停电时,主从设备切换、网络、人机接口站是否正常;系统检修重新上电后对各设备进行切换测试。
(2) System redundancy test: conduct redundancy test on redundant power supply, server and communication network. Pay attention to whether the master-slave equipment switching, network and man-machine interface station are normal in case of power failure of each equipment of the system; After system maintenance and power on again, switch and test each equipment.
(3)系统灰尘清除:系统停运对所有设备进行清扫吹灰,包括主机、控制站机笼、机柜滤网、风扇等部件的灰尘清理。
(3) System dust removal: after system shutdown, all equipment shall be cleaned and soot blown, including dust removal of host, control station cage, cabinet filter screen, fan and other components.
(4)接地系统检修。包括端子检查、对地电阻测试;系统供电线路检修,并对UPS进行供电能力测试;注意检查DPU主机CMOS电池电量,防止CMOS数据丢失。
(4) Maintenance of grounding system. Including terminal inspection and ground resistance test; Overhaul the system power supply line and test the power supply capacity of UPS; Pay attention to check the CMOS battery power of DPU host to prevent CMOS data loss.
(5)检查DCS系统和其他系统的接口,重要信号冗余处理,与其他系统的通信其具体情况采取单向传输和加装防火墙措施。
(5) Check the interfaces between DCS system and other systems, important signal redundancy processing and communication with other systems, and take one-way transmission and firewall measures according to the specific conditions.
(6)系统上电:系统大修后维护负责人确认条件具备,严格遵照上电步骤进行。
(6) System power on: after system overhaul, the person in charge of maintenance confirms that the conditions are met and strictly follows the power on steps.
