Problems solved by technology

[0004] However, when there are a large number of electric meters, manually entering and issuing the whitelist through the master station not only consumes a lot of labor costs, but is also prone to errors; in addition, the whitelist information depends on the master station to issue, resulting in a large loss of communication traffic and increasing communication costs. cost

Embodiment Construction

[0019] figure 1 It is a schematic flow chart of the method 100 for meter device communication provided by the embodiment of the present application. The method 100 can be applied to the meter reading system deployed by AMI, specifically, it can be used between the collector and the meter device In the meter reading system using PLC technology for communication. The metering device may be a smart electric meter, a smart water meter, etc. supporting PLC technology. The collector may be a data concentrator unit (Data Concentrator Unit, DCU for short).

[0020] In the embodiment of the present application, a smart electric meter supporting PLC technology (hereinafter referred to as electric meter) is taken as an example to illustrate the technical solution of the present application, but it is not limited thereto. The electric meter and the collector are connected through the power line, and the PLC protocol is used for communication, and the data transmission is carried out thr...

Abstract

The invention provides a method for communication of meter equipment. The method comprises the following steps that: a first collector receives on-line request information sent by first meter equipment, wherein the on-line request information includes the identification of the first meter equipment; and when the identification does not belong to the white list and the black list of the first collector, the identification of the first meter equipment is added into the white list of the first collector, and a first indication message including the identification is sent to a second collector, wherein the first indication message indicates that the second collector should add the identification of the first meter equipment into the black list of the second collector. Thus, the problem of crosstalk of access of PLC meter equipment is overcome.

Description

technical field [0001] The present application relates to the communication field, in particular to a method and a collector for communication of meter equipment. Background technique [0002] Power Line Communication (PLC) technology is a communication method that uses power distribution lines to transmit data. In a smart meter system based on Advanced Metering Infrastructure (AMI for short), PLC technology is widely used. The AMI master station collects data from the PLC meter through the collector, and the collector and the PLC meter are connected through power lines to communicate with each other. [0003] PLC meters are usually added to the smart meter system through an automatic discovery mechanism, that is, PLC meters are randomly connected to a collector. In this way, there may be crosstalk between multiple collectors deployed in the same station area, or multiple collectors deployed in different stations but with relatively close connections, that is, the PLC mete...
