EMC要求；包括CE、RE以及CS、RS、Surge、EFT、ESD等要求，對(duì)于不同的接口部分，采用不同的等級(jí)要求；如圖2所示。對(duì)裝置的可靠性、可維修性和預(yù)估的使用壽命；如可維修性驗(yàn)證：采用指示燈進(jìn)行指示，定位故障發(fā)生點(diǎn)，方便進(jìn)行維修；如可靠性運(yùn)行驗(yàn)證，運(yùn)行里程不少于10W公里，運(yùn)行時(shí)間不少于1年等要求；其他要求：如對(duì)于供電中斷、跌落等要求，一般模塊電源設(shè)計(jì)難滿足10mS中斷需求，尤其是對(duì)于低壓輸入產(chǎn)品，需要增加外圍輸入輸出電容滿足客戶需求；如對(duì)于蓄電池的短路保護(hù)措施，一般采用防反二極管或者機(jī)械設(shè)計(jì)來(lái)規(guī)避此方面的失效。
3HAC025097-00116機(jī)器人模塊,DSQC639使用過(guò)程車載電子設(shè)備的電源選型
隔離電源作為防止故障擴(kuò)散的方法之一，在車載電子設(shè)備中起著重要的作用；但是車載在運(yùn)行過(guò)程中，存在著各種狀態(tài)，如劇烈的振動(dòng)狀態(tài)；劇烈的外界環(huán)境溫度變化率等情況出現(xiàn)；普通常規(guī)的工業(yè)級(jí)電源很難滿足其使用要求；那么車載電路電源需要要求呢？
1.沖擊和振動(dòng)：
由于鐵路運(yùn)行環(huán)境的性質(zhì)，鐵道車輛會(huì)受到?jīng)_擊和振動(dòng)。對(duì)于安裝在鐵道車輛上的電子設(shè)備必須進(jìn)行隨機(jī)振動(dòng)和沖擊試驗(yàn)要求。對(duì)于電源模塊來(lái)說(shuō)，采用灌膠固定PCB板載元器件的方法，可有效增強(qiáng)其抗振動(dòng)和沖擊的能力。
如金升陽(yáng)鐵路電源R3系列產(chǎn)品可完全滿足振動(dòng)10~55Hz 10g 30Min along X Y Z要求。
車載蓄電池的額定供電電壓主要有以下幾種：24V、48V、72V、96V、110V等5種規(guī)格；由于輔助設(shè)備啟動(dòng)或者感性負(fù)載進(jìn)行切換，會(huì)產(chǎn)生浪涌電壓或者低電壓出現(xiàn)；電源設(shè)計(jì)的輸入電壓參數(shù)能夠在0.6VN和1.4VN電壓范圍內(nèi)正常工作；并且電源廠家都會(huì)兼容多個(gè)車載蓄電池電壓等級(jí)。
如1.金升陽(yáng)鐵路電源產(chǎn)品URB1D24YMD-6WR3，輸入電壓范圍為40VDC~160VDC，可兼容車載蓄電池72VDC、96VDC、110VDC三個(gè)供電電壓等級(jí)。
and with the help of PLC system, the interlocking control scheme for the operation of coke discharge system can be formulated.
The interlock control of the coke discharge system must be judged according to the above four conditions. If any condition occurs, the coke discharge system must stop running to ensure the reliability of the whole process flow. Among them, the operation signal of the circulating fan can be obtained through the feedback of the frequency converter, the cold coke temperature of C101 belt conveyor can be measured through the radiation pyrometer installed above the belt at the coke discharge port, the temperature of the rotary seal valve can be measured through the thermal resistance installed on the reserved port of the rotary seal valve housing, and the material level of the pre storage room can be measured through the radar material level meter and high-temperature electrostatic capacity material level meter installed at the interface of the pre storage room. These figures The analog signal is collected into the PLC digital and analog input module, and the logic calls the corresponding instructions to complete the preparation of the interlocking program. At the same time, according to the coke discharge process, the electric equipment of the coke discharge system should be started and stopped in a certain order. When it is opened, C102
