Description

technical field [0001] The invention belongs to the technical field of power control, and more specifically relates to a power line communication environment testing device and testing method. Background technique [0002] At present, one of the main ways of downlink communication in the power consumption information collection system is low-voltage power line carrier communication. Since the power carrier signal uses an open power line output, it is easily affected by the line environment and power load during transmission, causing carrier Communication is abnormal. [0003] After a communication failure occurs to a terminal device during on-site operation, due to the limited professional skills of the on-site maintenance personnel and the lack of professional maintenance tools, it is usually difficult to determine the cause of the failure on site, and it needs to be dismantled and sent for repair, which is time-consuming, laborious, and inefficient. The faults in the fiel...
