一种双PLC加冗余通讯方式的转运装置控制系统及方法
摘要：
本发明公开了一种双PLC加冗余通讯方式的转运装置控制系统及方法，包括设置在反应堆厂房RX侧的控制台和设置在燃料厂房KX侧的控制台，两侧控制台分别通过交换机与其PLC控制器连接，RX侧PLC通过RX侧轴位置编码器与RX侧离合器连接、通过RX侧驱动器与RX侧电机连接；KX侧PLC控制器通过KX侧轴位置编码器与KX侧离合器连接、通过KX侧驱动器与KX侧电机连接、通过小车位置双编码器与运输小车连接;两侧PLC通过以太网和硬接线冗余方式连接，保证网络正常、中断时都能完成运输小车的电动接力，该系统还具有离合器纠偏能力。通过本发明解决了转运装置的控制技术问题，提高转运装置运行的安全性、可靠性和高效性。
摘要（英）：

The invention discloses a transfer device control system and a method of a dual Programmable Logic Controller (PLC) and redundant communication mode. The system comprises a control platform arranged on a reactor factory RX side and a control platform arranged on a fuel factory KX side, control platforms arranged on two sides are connected to PLCs through exchangers respectively, the PLC of the RX side is connected to an RX side clutch through an RX side shaft position coder and is connected to an RX side motor through an RX side driver, the PLC of the KX side is connected to a KX side clutch through a KX side shaft position coder, is connected to a KX side motor through a KX side driver and is connected to a conveying trolley through a trolley position dual coder, PLCs arranged on two sides are connected through the Ethernet in a hard-wired redundant mode, the network can complete the electric connection of the conveying trolley in the normal state and the breaking state, and the system also has the clutch correction capability. By the aid of the method and the system, the control technical problem of the device is solved, and the safety, the reliability and the high-efficiency of the device operation is improved.
