SDCS-CON-4工控卡件，3ADT313900R1501使用配置手册
城轨信号系统采用了高度集成的系统平台，同时基于云计算技术，利用服务器集群，在硬件设备层面将原有的中心系统和车站级系统合并，超越独立系统的局限性，将各个系统的信息进行集中采集、处理、统计和分析。地铁列车运行的安全重于泰山，如果说城轨信号系统是列车的大脑，那么供电设备则是系统的心脏，安全可靠的供电不仅保证信号系统内所有重要的设备持续运转，更需确保避免因系统停机和掉电而引起信号中断甚至是事故的发生。
SDCS-CON-4工控卡件，3ADT313900R1501使用配置手册昆明4号线城轨信号系统关键子系统的供电（如联锁系统）均采用冗余供电设计，每一路24VDC供电均配置额外的开关电源，确保在一台电源故障的情况下另外一台电源仍然能够提供负载所需的功率，进一步加强了供电的可靠性。选用高品质、高可靠的开关电源解决方案，是工程师们设计昆明4号线城轨信号系统的优先考虑项，作为菲尼克斯电气高品质、智能化代表的QUINT产品家族，为昆明4号线项目提供了不同功率且功能丰富的解决方案。
冗余供电系统通常由AC/DC开关电源和冗余模块构成，多台开关电源通过冗余模块进行并联，一方面保证供电的持续性，冗余模块也能防止单个开关电源故障或者异常影响到其它开关电源。· 4KV的防浪涌等级，有效提高输入侧的抗冲击能力，同时掉电缓冲时间可以在20ms或以上（根据产品规格不同），确保保证输入侧异常下的供电可靠性。
· 125%持续运行的静态功率裕度（以具体产品规格为准），200%可运行5 s的动态功率裕度（以具体产品规格为准），可一定程度避免现场过载带来的不良影响。
· SFB（选择性触发）技术可保证多路负载出现短路现象时迅速的选择性触发短路支路的断路器脱扣，解除故障回路，保证电源不停机并持续确保其它支路的负载正常工作。engineering quantity conversion, and the ai\aq register can be accessed directly. It is very convenient in analog signal processing, saving a lot of programming time; The host also supports 32 PID instructions; More importantly, one host can do it without adding additional expansion module PID instructions, that is, the PID instructions in the special control instructions, which are supported by the whole series of PLC of Haiwei. According to the change of load, the system adjusts the parameters in combination with the real-time curve table of the software during online monitoring, and adjusts the three PID parameters one by one to achieve the best effect. After the parameters are adjusted and adjusted, the fast regulation and stable output of voltage are realized, and the closed-loop management of power supply is realized, which provides a good foundation for better magnetron sputtering coating. Most mechanical equipment manufacturers that use PLC cannot grasp the dynamic information such as the operation status of the sold equipment and production line in time and accurately, and the faults cannot be diagnosed and maintained in time.
