摘　　要：低压电力线高速载波通信(HPLC)相关设备和算法在研发时缺乏便捷、可靠的测试系统,为此,设计一种多功能HPLC组网测试系统。该系统由中央控制单元、多功能测试单元和路由衰减器三种组件组成。系统工作时,由中央控制单元远程控制多功能测试单元和路由衰减器,多功能测试单元组成电力载波组网中的多种通信节点,路由衰减器控制各个节点之间的信号衰减。所设计的组网测试系统能够生成动态自适应白噪声,用于代替传统的屏蔽箱来屏蔽串扰信号;还能够对被测设备通信信号进行模拟延迟、模拟噪声和模拟衰减等处理,在实验室复现真实电力线载波组网测试环境。该系统用于验证拓扑识别等算法或测试HPLC相关设备,能够为繁杂的场外实验节省大量时间、人力和资金投入。In allusion to the lack of convenient and reliable test system during the development of HPLC related equipment and algorithm,a multifunctional HPLC networking testing system is designed.The system is composed of central control unit,multifunctional test unit and routing attenuator.When the system works,the central control unit can remotely control the multifunctional test unit and the route attenuator.The multifunctional test unit is used to constitute a variety of communication nodes in the power carrier network,and the route attenuator is used to control the signal attenuation between each node.The designed networking test system can generate dynamic adaptive white noise,which can be used to shield crosstalk signals instead of the traditional shielding box.It can also simulate delay,noise and attenuation of the communication signal of the tested equipment,and reproduce the real test environment of power line carrier network in the laboratory.The system can be used to verify algorithms such as topology recognition or test HPLC related equipment,which can save a lot of time,manpower and capital investment for complicated off⁃site experiments.
