Device and method for measuring household-meter relation without entering household

Abstract

The invention relates to the field of electric flux detection equipment and particularly discloses a device and a method for measuring the household-meter relation without entering a household. The device comprises a multi-frequency-point signal generation device, a multi-station wave-blocking device and a directional signal identification device. The multi-frequency-point signal generation deviceis connected to the wire outlet end of an electric energy meter and can feed an identification signal to the user direction. The multi-station wave-blocking device is connected to the wire inlet endof the electric energy meter, and is used for blocking the identification signal from passing through the wire inlet end of the electric energy meter. The directional signal identification device comprises a directional receiving antenna, and the directional receiving antenna can receive the identification signal directionally so as to confirm a user connected with the electric energy meter. According to the invention, the household-meter relation identification can be carried out without entering the household. Meanwhile, the advantages of fast identification speed, high efficiency, simple structure, low manufacturing cost and convenient usage are realized.

Description

technical field [0001] The invention relates to the field of electric communication detection equipment, in particular to a device and method for testing the relationship between household meters without entering the household. Background technique [0002] The household meter relationship refers to the corresponding relationship between each meter installed centrally and the actual residents of each household after the centralized installation of meter boxes for urban and urban residents. Because the wires and cables between the electric meter and the residents' homes are often embedded in the wall, they cannot be identified by direct observation; due to reasons such as construction and marking not strictly in accordance with the drawings, etc., there are often errors in the correspondence between the electric meter and the residents' homes or information on power files Incorrect; resulting in the inconsistency between the electricity bill paid by the user and the actual el...

Problems solved by technology

[0004] In case of line failure, the location of the failure cannot be found according to the error file information. If you check one by one, it will consume a lot of manpower and material resources, and may turn off the power by mistake, which will bring great inconvenience to users' life.

[0005] If it is necessary to correct multi-household and multi-storey wrong tables, it takes a lot of manpower and time according to the traditional manual operation method, and it needs to be opened one by one, and multiple people and multiple confirmations are required

[0006] At present, there are also some devices for household table relationship identification, but they all identify single households or need to enter the user's home for identification, which brings inconvenience to the user. At the same time, the recognition speed is greatly slowed down and the efficiency is low.

For example, the patent number is CN106019051A, and the invention patent titled "Electronic Energy Meter Non-House-to-House and Serial-to-Household Detection Equipment" uses the signal feed-in device and wave blocking device to realize the short-wave transmission on the power line of a certain electric energy meter user side, through The signal strength received by the short-wave antenna is used to judge the corresponding user of a certain electric energy meter, which realizes the method of single-form user’s non-entry test, but it needs to scan and detect the corresponding electric energy meter user door-to-door, and there are repeated actions in the operation, if To test 10 meters or even more, it is necessary to repeat the above operation 10 times or more, which wastes time and manpower; for example, the patent number is 201620628434.0, a utility model patent named "A Device for Identifying Electricity Meters for Users", which is available in Install a signal wave trap on the incoming line of the meter, plug in a signal generator in the socket of the user's home, and then detect the detection signal sent by the signal generator through the signal checker installed at the outgoing line of the electric meter

This detection process needs to enter the user's home, which brings inconvenience to the user, and needs to identify each user one by one. The operation is time-consuming and laborious, and many parts are required, and the manufacturing cost is high.
