下面将结合本发明优选的实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
见图1，一种车载局部网络系统，包括有主控单元1、混合线缆和若干个智能电器终端2，混合线缆内置有用于供电输送的电源线和用于信号输送的信号线，若干个智能电器终端2均接入到混合线缆上，通过混合线缆与主控单元1连接；其中，混合线缆包括有主混合线缆3和若干个分支混合线缆4，主混合线缆与主控单元连接，主混合线缆和若干个分支混合线缆上均连接有对应的智能电器终端，每个分支混合线缆4均通过对应的转接终端5与主混合线缆3连接，转接终端5将主混合线缆3的电源线和分支混合线缆4的电源线对应连接、将主混合线缆3的信号线和分支混合线缆4的信号线对应连接。
见图2，控制单元1包括有逻辑控制单元11、电源管理单元12、电流传感器13、电源保护部件-MOSFET管14、混合卡线接插件15、电源端口16和总线端口17，电源端口16与混合卡线接插件15内的电源电极之间串接有电源保护部件-MOSFET管14和电流传感器13，电源保护部件-MOSFET管14的控制端与电源管理单元12的DO端口连接，电流传感器13的输出端与电源管理单元12的AD转换端口连接，电源管理单元12、混合卡线接插件15的信号电极、总线端口17均与逻辑控制单元11连接。其中的逻辑控制单元11通过混合卡线接插件15实现对连接在混合线缆上的智能电器终端进行管理和控制；其中的电源管理单元12通过检测电流传感器13的电流值来控制电源保护部件-MOSFET管14的通断；当混合接插件15所连的混合线缆上的各本地电器的工作状态不变时（即本地电器或是接通工作状态、或是断开电源处于待机状态，均处于一个稳定的工作状态），此时混合线缆上的工作电流值变化较小，当电流传感器13检测的工作电流值与电源管理单元12存储的各接通的智能电器终端的额定电流值的和比较结果偏差较大属于异常状态，当检测的电流值过大时有可能是混合线缆对地短路或混合线缆上的某智能电器终端对地短路，前一种状态（混合线缆对地短路）下，电源管理单元12控制电源保护部件-MOSFET管14断开电源、后一种状态（混合线缆上的某智能电器终端对地短路）下，主控单元通过混合线缆发送命令控制该智能电器终端断开电源，电源保护部件-MOSFET管14断开电源或智能电器终端断开电源的同时，将故障信息上传；当本地电器在闭合或断开操作时，此时混合线缆上的工作电流会有相应变化，当电流传感器13采集的电流变化量与额定的电流变化量差异较大时，主控单元控制该智能电器终端断开电源，并将故障信息上传。
其中，转接终端5是一个包含两个混合卡线接插件6的一体化部件，其中一个混合卡线接插件6与主混合线缆3连接，另一个混合卡线接插件6与分支混合线缆4连接，两个混合卡线接插件6之间的电源电极对应连通、信号电极对应连通。工程应用中，转接终端5可以添加其它的辅助功能以便更有效的实施对分支混合线缆4的监控和保护，例如在主混合线缆3的电源线和分支混合线缆4的电源线之间加保险丝（或带有电源保护功能的智能功率器件），在主混合线缆3信号线和分支混合线缆4信号线之间加滤波器等。
若干个智能电器终端2包括有一体式智能电器终端 （见图8）、连接式智能电器终端（见图3）和多元智能电器终端（见图4），其中，一体化智能电器终端由本地电器21与混合卡线接插件6一体化构成，连接式智能电器终端由一个本地电器21与混合卡线接插件6通过引线22连接而成，多元智能电器终端是由若干个本地电器21与混合卡线接插件6通过引线22连接而成，本地电器21通过对应的混合卡线接插件6接入到混合线缆上。
