Networking method<\/b> :<\/b><\/h3>\n

RS-485 and M-BUS:<\/p>\n

RS-485 is a four-wire system with positive and negative poles and two communication lines A and B. The lines must correspond. The working voltage of the water meter is 12-24V.<\/p>\n

M-BUS is a two-wire system with only positive and negative poles and no correspondence. The working voltage of the water meter is 24-36V.<\/p>\n

Wired architecture<\/b> :<\/b><\/h3>\n

System + acquisition equipment + wired communication water and electricity meter<\/p>\n

Main equipment<\/b> :<\/b><\/h3>\n

Intelligent meter reading management platform, concentrator, collector, wired communication (RS-485, M-BUS) water and electricity meter<\/p>\n

Configuration requirements<\/b> :<\/b><\/h3>\n

One concentrator can carry 20 collectors with a maximum distance of 1200m, and one collector can carry up to 128 (generally no more than 100) water meters or electricity meters with a maximum distance of 300m.<\/p>\n

Wired and wireless<\/b> :<\/b><\/h3>\n

What are the advantages of wired and wireless solutions?<\/p>\n

Wireless is more convenient. You only need to install the water and electricity meter and debug it online. No wiring is required. In a project, the wireless solution is simpler.<\/p>\n

The wired solution will be more stable in terms of communication in the future.<\/p>\n
