Distribution room automatic identification tester and identification method thereof

Abstract

The invention relates to a distribution room automatic identification tester and an identification method thereof. The invention aims to provide the distribution room automatic identification tester and the identification method thereof which can increase the communication distance, and accurately identify distribution rooms which users belong to simultaneously. The technical scheme is that the distribution room automatic identification tester is characterized by comprising a master control end placed at a low voltage output end of a transformer and a plurality of servers positioned at power line user ends, wherein the mater control end and the servers are connected through coupled circuits and power lines respectively so as to achieve the coupling and separation of carrier signals. The distribution room automatic identification tester and the identification method thereof are applicable to automatic partition of the distribution rooms which users on the power utilization sides of the transformer belong to.

Description

Technical field [0001] The invention relates to an automatic station area identification tester and an identification method thereof, and is mainly suitable for the automatic division of a user's home station area on the power consumption side of a transformer. Background technique [0002] In view of the complicated wiring of some users in some stations, it is difficult to find out the transformers to which users belong under the condition of uninterrupted power supply, and it is impossible to calculate the line loss in the station area, and it is impossible to distinguish the occurrence of power theft, especially the current AIM / AMR systems in various countries. With extensive use, the identification of the user's station zone ownership problem is also imminent. The Chinese invention patent with the patent number 200810114907.5 discloses a station area identification device, which includes a start unit for injecting carrier signal into the power line, and a terminal unit for re...

Problems solved by technology

[0002] In view of the complex wiring of users in some station areas at present, it is difficult to find out the transformer to which the user belongs under the condition of continuous power supply, and it is impossible to realize the calculation of line loss in the station area, and it is impossible to distinguish the occurrence of power theft, especially the AIM / AMR systems in various countries. With extensive use, it is imminent to determine the user's station area attribution

The Chinese invention patent with the patent number of 200810114907.5 discloses a station area identification device, which includes a start-end unit for injecting a carrier signal into the power line, and a terminal unit for receiving the carrier signal and determining the station area to which the user belongs. The two pass through the power line Carrier signal transmission, because the power line carrier signal of the starting unit can pass through the transformer from other stations to transmit the signal to the terminal unit, that is, the terminal unit can receive signals from other starting units, resulting in identification failure

On the other hand, due to the interference of various equipment such as electrical appliances during power line carrier communication, coupled with the attenuation of the power line itself, the distance between point-to-point communication on the power line is limited
