What is the point table of 485 transmission?

485 meter is based on the single-phase electronic energy meter, adding RS-485 interface, suitable for the bottom of the RS-485 network mode of centralized reading, centralized control power management system, change the traditional meter reading or payment and the control mode of the meter, through the RS-485 network, convenient and accurate copy meter electricity, pre-payment and control of the meter on and off.

3, 485 meters using large-scale integrated circuits and advanced manufacturing technology, and the selection of well-known brands of long-life components, in accordance with GB\/T17215-2002 and GB\/T18460.3-2001 standard production, communication protocol in line with DL\/T645-1997 \"Multi-function electricity meter communication protocol\" power industry standards. The product has strong structure, excellent performance, high reliability, no adjustment and high overload capacity.


Hello, the 485 transmission point table refers to the point information table transmitted in the 485 bus, including the status of each control device, control commands and other information, used to achieve data communication and control between devices. Each point in the point table has a unique address through which read and write operations can be performed on the bus. Point tables are usually provided by system integrators or equipment manufacturers, and users can customize and configure them according to their own needs.


1. It is connected to each meter through the 485 line using the handle.

2. Then the concentrator collects the power value, current, voltage and other data of each meter through the 485 line.

3. Then the concentrator communicates through GPRS. Upload to the main station.

4. Then enter the intelligent energy consumption system through the server for data and cost calculation, customer information push, etc.
