TL;DR: In this article, a method for automatically searching an electric meter address below a collector is proposed, which can reduce maintenance work of an electric power information collecting system, reduce maintenance cost, and increase running effect of the collecting system.
Abstract: The invention discloses a method for automatically searching an electric meter address below a collector, comprising the following steps: 1, a concentrator sends a wildcard address to the collector and excites the collector to collect the data of all electric meters; 2, the collector sends the data collected in 1-3S back to the concentrator, and the concentrator analyzes the collected data, wherein the analysis process is that: (1) if no data is input, no electric meter is accessed; (2) if a complete data is received and no other data is followed, a single electric meter is accessed; (3) if the searched data is messy codes, error messages or correct message and other data is followed, a plurality of electric meters are accessed; 3, and when search shows that a plurality of electric metersare accessed, the wildcard address is replaced to repeat the step 1 and the step 2 till the address of the single electric meter is searched. The method can reduce maintenance work of an electric power information collecting system, reduces maintenance cost, and increases running effect of the collecting system.

TL;DR: In this paper, the authors proposed an electric charge meter reading payment method based on a two-dimensional code, which solves the problem that the existing electric charge payment needs a payment list and the charge needs to be paid in the bank, and is simple and practical.
Abstract: The invention relates to an electric charge meter-reading payment method based on a two-dimension code. The electric charge meter-reading payment method is characterized by comprising the following steps: step S01. collecting electric meter data by a remote electric charge meter reader in real time and sending the collected electric meter data to a remote electric-power electric charge management system; step S02. linking monthly power data of an ID (Identity Card) with internet-bank electric charge payment to generate a two-dimension code when the remote electric-power electric charge managing system calculates the electric charge every month according to the ID of a user; step S03. sending the two-dimension code to a remote electric charge meter reader of the corresponding ID to display; and step S04. scanning the two-dimension code by the user through a mobile phone to obtain power consumption data and register the internet-bank through the payment linkage to carry out mobile phone payment. The electric charge meter-reading payment method disclosed by the invention solves the trouble that the existing electric charge payment needs a payment list and the charge needs to be paid in the bank, and is simple and practical.

TL;DR: In this article, a method and a system for testing an electricity consumption information acquisition system, and a master station, is described, where the master station transmits a meter reading command to a concentrator, and the concentrator starts to locally automatically read a meter regularly, cyclically reads one or more electric meters within preset time to read a plurality of response data returned by the electric meters, and records a receiving state of the response data.
Abstract: The invention discloses a method and a system for testing an electricity consumption information acquisition system, and a master station. The method comprises the following steps that: the master station transmits a meter reading command to a concentrator; the concentrator starts to locally automatically read a meter regularly, cyclically reads one or more electric meters within preset time to read a plurality of response data returned by the electric meters, and records a receiving state of the response data; the master station transmits a command for reading all the response data from the concentrator; and the master station reads all the response data from the concentrator, and counts a success rate of meter reading according to the receiving states of all the response data, wherein under the condition that the response data are effective, the master station stores the response data and successfully reads a meter; and under the condition that the response data are ineffective or no response data is received, the master station fails to read the meter. By the method and the master station, the efficiency of regularly reading the electric meter data by the system within appointed time can be inspected conveniently and efficiently, and the reading instantaneity and the reliability of regular meter reading are improved.
