風(fēng)電場環(huán)境惡劣，為了保證控制系統(tǒng)準(zhǔn)確傳輸數(shù)據(jù)，增強(qiáng)can總線節(jié)點(diǎn)的抗干擾性能， sja1000控制器經(jīng)過高速光藕6n137隔離后與收發(fā)器tja1050相連，實(shí)現(xiàn)總線上各can節(jié)點(diǎn)之間的電氣隔離。采用dc-dc電源隔離模塊dcr010505，實(shí)現(xiàn)光耦兩端的電源隔離。canh接總線的高電平端，canl接總線的低電平端。由于風(fēng)電機(jī)組垂直距離較高，容易受雷電的影響，在兩根can總線輸入端與地之間分別并聯(lián)一30pf的電容和一防雷擊管，以濾除高頻干擾和防止浪涌電壓。

4 CAN接口通訊軟件設(shè)計(jì)

對(duì)于can的通訊程序，采用分層處理的方法，包括驅(qū)動(dòng)層和應(yīng)用層。因此，can接口軟件通訊包括兩部分：can驅(qū)動(dòng)程序和can應(yīng)用程序。驅(qū)動(dòng)程序負(fù)責(zé)完成linux內(nèi)核與sja1000之間的數(shù)據(jù)通訊，即linux內(nèi)核設(shè)置sja1000的控制寄存器，讀寫sja1000接收、發(fā)送緩沖器。應(yīng)用程序部分負(fù)責(zé)完成用戶空間和內(nèi)核空間的數(shù)據(jù)交換，以及分析從sja1000接收到的報(bào)文，封裝要發(fā)送報(bào)文。接收的報(bào)文主要包括來自變流模塊和變槳偏航控制模塊的機(jī)組狀態(tài)信息及風(fēng)速風(fēng)向、各類溫度和轉(zhuǎn)速信號(hào)等。發(fā)送的報(bào)文包括下發(fā)給變流模塊和變槳偏航控制模塊的控制指令及控制參數(shù)。
