3 通信模塊
3.1 RS-422通信標準
RS-422標準的數據信號采用差分傳輸方式,也稱作平衡傳輸,其全稱是“平衡電壓數字接口電路的電氣特性”。
其接收器采用高輸入阻抗,發送驅動器有比RS232更強的驅動能力,故允許在相同傳輸線上連接多個接收節點,zui多可接10個節點。即一個主設備(Master),其余為從設備(Salve),從發備之間不能通信,所以RS-422支持點對多的雙向通信。
RS-422的zui大傳輸距離為4000英尺(約1219m),zui大傳輸速率為10Mbit/s。
3.2 數據交換功能實現
本系統通信模塊采用RS-422標準,線路長度約為200m,故通信的可靠性可得到保證。差分線路驅動器使用AM26LS31芯片,差分接受器使用AM26LS32芯片,微處理器的串行輸出口和輸入口分別與驅動器輸入和接收器輸出相連,并使用差分開路自動故障保險終端連接配置。
從而在發送器輸出端為高阻狀態時保證接受器輸入有至少200mV的電壓信號,使輸出不會出現未知的狀態,提高可靠性,完成與上位機間的數據交換工作。另外,考慮到多機器人手臂的應用情況,在手臂控制器中設有撥碼開關來設定編號,與上位機的數據交換必須包含該編號,并由此來判斷通信時目標控制器的具體位置。
