摘　　要：广州—佛山地铁既有一、二期共33列车的运行逻辑控制系统采用的是机械触点、中间继电器、时间继电器,通过硬线连接所构成的列车控制系统,其中60%以上的列车故障是由于继电器故障引起。因此,在2018年新增购的18列车上创新的引进了二乘二取二无触点逻辑控制单元(LCU),代替传统的继电器有触点硬接线控制系统,以避免传统继电器控制系统故障率高的不足,其具有网络化、智能化、高可靠性、长寿命的优点,更好的保障列车的安全运行,达到了免维护、高效检修的目标。The operation logic control system of the 33 trains of the first and second phases of Guangfo Metro is a train control system consisting of mechanical contacts,intermediate relays and time relays connected by hard wires,more than 60%of the train faults are due to faults of relays.Therefore,in the 1818 newly purchased 18 trains,the innovative introduction of the 2 out of 2 contactless logic control unit(LCU)replaced the traditional relay with contact hard-wired control system to avoid the failure rate of the traditional relay control system.It has the advantages of network,intelligence,high reliability and long life.As a result,it betterly guarantees the safe operation of the train,and achieves the goal of maintenance-free and efficient maintenance.
