In recent years, the Internet of Things technology has developed rapidly, promoting the life of the public and improving efficiency. Compared with the previous manual meter reading system, the remote prepaid water meter has obvious advantages. It is no longer necessary to send people to read the meter from door to door, and the data accuracy is improved. So, what are the current installation schemes for remote prepaid water meters?
Water meter scheme I: centralized installation scheme of water meter
The water meter and the collector are connected with 485 lines. The collector and the water meter are placed in the well together. One collector can collect 256 water meters. The collector can be connected with 4G-LTE flow card or network cable. This scheme is suitable for centralized installation of water meters. For example, there are 20 water meters in a well that are relatively centralized. After 20 water meters are connected in parallel, the two outgoing lines are connected to the collector.
Scheme II of water meter: decentralized installation scheme of water meter
The water meter and the collector are connected wirelessly. The wireless distance is within 500 meters, and the water meter within 500 meters from the collector will automatically connect with the nearest water meter and transmit signal data. This scheme is suitable for the scattered installation of water meters. For example, each water meter is installed separately in the room, and one collector can collect hundreds of water meters. The collector uses 4G-LTE flow card or network cable for networking.
