SDCS-CON-4工控卡件，3ADT313900R1501使用配置手冊
城軌信號系統(tǒng)采用了高度集成的系統(tǒng)平臺，同時基于云計算技術(shù)，利用服務器集群，在硬件設(shè)備層面將原有的中心系統(tǒng)和車站級系統(tǒng)合并，超越獨立系統(tǒng)的局限性，將各個系統(tǒng)的信息進行集中采集、處理、統(tǒng)計和分析。地鐵列車運行的安全重于泰山，如果說城軌信號系統(tǒng)是列車的大腦，那么供電設(shè)備則是系統(tǒng)的心臟，安全可靠的供電不僅保證信號系統(tǒng)內(nèi)所有重要的設(shè)備持續(xù)運轉(zhuǎn)，更需確保避免因系統(tǒng)停機和掉電而引起信號中斷甚至是事故的發(fā)生。

冗余供電系統(tǒng)通常由AC/DC開關(guān)電源和冗余模塊構(gòu)成，多臺開關(guān)電源通過冗余模塊進行并聯(lián)，一方面保證供電的持續(xù)性，冗余模塊也能防止單個開關(guān)電源故障或者異常影響到其它開關(guān)電源?！?4KV的防浪涌等級，有效提高輸入側(cè)的抗沖擊能力，同時掉電緩沖時間可以在20ms或以上（根據(jù)產(chǎn)品規(guī)格不同），確保保證輸入側(cè)異常下的供電可靠性。
· 125%持續(xù)運行的靜態(tài)功率裕度（以具體產(chǎn)品規(guī)格為準），200%可運行5 s的動態(tài)功率裕度（以具體產(chǎn)品規(guī)格為準），可一定程度避免現(xiàn)場過載帶來的不良影響。
· SFB（選擇性觸發(fā)）技術(shù)可保證多路負載出現(xiàn)短路現(xiàn)象時迅速的選擇性觸發(fā)短路支路的斷路器脫扣，解除故障回路，保證電源不停機并持續(xù)確保其它支路的負載正常工作。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.
