Method and device for determining region of ammeter by detecting signal intensity

Abstract

The invention discloses a method and a device for determining a region of an ammeter by detecting signal intensity. According to the method, when a master station discovers that two concentrators collects the data transmitted by the same ammeter, the two concentrators are enabled to detect the intensity of a received signal transmitted by the ammeter, the ammeter can be determined to belong to a party with high receiving signal intensity, so that the crosstalk problem in an automatic meter reading system can be solved. The device comprises a signal collecting module, a concentrator data transmission module, a signal intensity detection module and a region determining module, wherein the signal collecting module is used for respectively collecting the data transmitted by the ammeter in each region for the corresponding concentrator; the concentrator data transmission module is used for transmitting the data of the ammeter, collected by each concentrator, to the master station; the signal intensity detection module is used for transmitting a command for enabling the two concentrators to respectively detect the intensity of the signal transmitted by the same ammeter when the two concentrators are discovered by the master station to collect the data transmitted by the same ammeter; the region determining module is used for judging that the same ammeter belongs to the region corresponding to the concentrator with high received signal intensity.

Description

technical field [0001] The invention relates to an automatic meter reading system, in particular to a method and a device for determining the station area to which the electric meter belongs in the automatic meter reading system. Background technique [0002] The automatic meter reading system of prior art such as figure 1 shown. Among them, the 220V terminals of each transformer (such as 10KV medium voltage) 110, 210 are connected to a concentrator 120, 220 to manage all the electric meters 130, 230 under it. This meter reading range is called a station area, and each electric meter in the station area Send the meter readings to the concentrator in the station area, and the concentrator uploads the collected data wirelessly (or in other ways) to the main station (ie, the data processing center, not shown). [0003] In addition, the control signal of the main station is also transmitted to each meter through the concentrator. [0004] During the actual operation of the sy...

Problems solved by technology

However, this method needs to set up special signal transmitters and detectors, resulting in increased costs

In addition, setting the frequency of each signal transmitter to send signals between 1000Hz and 40MHz and making them different from each other will also bring a lot of inconvenience to the actual operation
