Method for managing address of metering equipment, collection terminal and metering equipment

Abstract

Embodiments of the present invention provide a method for managing an address of a metering device, a collection terminal, and a metering device. The method includes: the collecting terminal sends a first signal to a target metering device, and sends a second signal to the remaining metering devices connected to the collecting terminal except the target metering device, the first signal instructs the target metering device to respond to the sending by the collecting terminal The second signal indicates that the other metering devices do not respond to the address protocol message; the collecting terminal broadcasts the address protocol message, and the address protocol message is used to query or set the physical address of the target metering device. In the method for managing the address of the metering device according to the embodiment of the present invention, the target metering device responds to the address protocol message broadcast by the acquisition terminal according to the first signal, so that the acquisition terminal can automatically set and query the physical address of the metering device, and solve the problem of manual configuration of the metering device. The problem of calculating the physical address of the device.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a method for managing addresses of metering devices, a collection terminal and metering devices. Background technique [0002] In the Advanced Metering Infrastructure (AMI) system, the collection terminal and the meter can be connected through the Recommended Standard (RS)-485 bus, and based on the International Electrotechnical Commission (International Electro technical Commission, IEC )62056 protocol to transmit data. Among them, the link layer protocol applicable to the RS-485 bus is the IEC62056-21 protocol. [0003] Since the RS-485 bus is a half-duplex shared medium, it is determined that as long as one meter sends data, other meters on the same bus cannot send data, and the data sent by this meter will be transmitted by all meters on this bus. meter received. Each meter on the same bus must have a unique physical address. The physical address ran...

Problems solved by technology

In this way, the collection terminal sends the first signal to the target meter device, and sends the second signal to other meter devices connected to the collection terminal except the target meter device, so that the target meter device can respond to the address protocol broadcast by the collection terminal At the same time, the remaining metering devices connected to the collection terminal do not respond to the address protocol message, so that the collection terminal can automatically query and set the physical address of the metering device, and solve the problem of manually configuring the physical address of the metering device
