Method for solving information acquisition of area to which electric meter belongs

Abstract

The invention relates to a method for solving information acquisition of an area to which an electric meter belongs. According to the method, a host machine is connected below a transformer or concentrator at the area, a subordinate machine is connected at one end of a measured meter, the host machine carries out encoding through adjusting a power frequency zero point position, and broadcasts and transmits a code sequence containing information of the area in turns at A / B / C three phases, while a receiving end subordinate machine receives and demodulates information transmitted by the host machine, and the information comprises an area number and a phase position; and the functions of the subordinate machine can be realized by a carrier wave electric meter through direct compatibility. The invention provides the method for solving the information acquisition of the area to which the electric meter belongs and is combined with a current area power line carrier collecting scheme, the method is free from influence of severe environment, strong noise and high attenuation of a power line channel, and safely and reliably solves the problem that which area the electric meter belongs to can not be accurately judged, powering off is not needed, and the required information can be obtained through the automatic judgment of the electric meter.

Description

technical field [0001] The invention relates to a method for solving the problem of obtaining information on the station area to which the electric meter belongs, and belongs to the technical field of power line communication. Background technique [0002] At present, there are various problems in the collection and copying areas in various parts of my country. Therefore, it is difficult to find out the transformer to which the user belongs when the power supply is uninterrupted. These problems include: (1) The wiring of users in the old station area is complicated and the information is incomplete; (2) The new station area is adjacent to each other, and there are often multiple transformers in the same power distribution room. Due to the close proximity, they are also the same group of high-voltage buses , it is easy to copy and receive ammeters that do not belong to the station area; (3) The carrier signal is partially coupled between different phases. Most new station are...

Problems solved by technology

[0009] In view of the above-mentioned shortcomings of the prior art, the present invention provides a method that can accurately solve the problem of obtaining the information of the station area to which the electric meter belongs, and combines with the existing power line carrier copying scheme of the station area, which can not be affected by the harsh environment of the power line channel, high noise and high The impact of attenuation can safely and reliably solve the problem that it is impossible to 100% determine the station area to which the meter belongs. There is no need to cut off the power, and the required information can be obtained by the automatic judgment of the meter
